Description:FIELD OF THE INVENTION

[0001] The present invention relates to a travel neck support device with noise reduction that is developed to enhance user comfort in varying environments by dynamically reducing noise, maintaining optimal body support for healthy posture, regulating temperature to improve rest quality and ensuring wellness and uninterrupted sleep during travel or in noisy surroundings.

BACKGROUND OF THE INVENTION

[0002] During travel or prolonged rest in noisy or changing environments, users face several challenges. Conventional cushions fail to provide consistent body support, leading to neck strain and discomfort. Earplugs or basic noise-reducing tools are ineffective against varying sound frequencies, leaving users exposed to disruptive noise. Similarly, simple masks only block light partially and cannot adapt dynamically, compromising sleep quality. Temperature variations also present a challenge, as ordinary products cannot actively regulate warmth or cooling, resulting in thermal discomfort. Furthermore, lack of integration, forcing users to rely on multiple accessories that address issues individually without offering a holistic approach. This creates inconvenience, reduced efficiency, and poor user satisfaction, ultimately leading to fatigue, disturbed sleep cycles, and limited restorative benefits.

[0003] Traditionally, users rely on multiple manual tools such as standard neck pillows, earplugs, eye masks, portable fans, hot packs and handheld massagers to achieve comfort during travel or rest. Each of these tools works in isolation and requires manual adjustment, making their use inconvenient and inefficient. For example, ordinary neck pillows provide limited support, forcing constant repositioning, while earplugs or simple headphones block sound poorly and be frequently adjusted to fit. Similarly, eye masks need to be manually secured and removed, creating discomfort, and manual cooling or heating packs lose effectiveness quickly, requiring user intervention. Handheld massagers or vibration tools demand additional effort to operate and cannot be used comfortably while resting, further disrupting relaxation. This reliance on inconsistent, manually managed tools creates difficulties in maintaining ergonomic support, effective noise management, stable temperature and overall comfort, ultimately reducing sleep quality and travel wellness.

The flexible compression part is arranged to wrap the sound filtering part, the compressibility of the flexible compression part can be well attached to external auditory canals of different sizes, the external auditory canals are not hurt by the flexible characteristic of the flexible compression part, and the user experience is better. Meanwhile, the rope body is connected with the two earplug heads, the situation that one earplug head is lost is not prone to occurring, and when the earplug head needs to be pulled out from the external auditory canal, the earplug head can be pulled out through the rope body.

[0005] US6409694B1 discloses a ventilated neck brace that provides support to the wearer's neck while providing improved ventilation and breathability. Most embodiments of the neck brace include an elongate member that defines a neck support, a transition section, and an elongate shoulder rest. Most configurations of the neck brace allow the wearer to adjust the width and length of the neck brace.

[0006] Conventionally, many devices have been developed to provide neck support, reduce noise, control light, regulate temperature, and offer relaxation during travel, but these devices lack integration, adaptability and automation. These existing devices function in isolation, require constant manual adjustment and fail to dynamically respond to changing environmental conditions or user needs. This results in discomfort, interrupted rest and reduced effectiveness.

[0007] In order to overcome the aforementioned drawbacks, there exists a need in the art to develop a device that requires to be capable of adapting to user posture, cancelling unwanted noise, shielding from light and providing relaxation features to enhance comfort, ensures uninterrupted rest, improves ergonomic alignment for promoting health, safety and overall well‑being during travel or extended resting periods.

[0008] An object of the present invention is to develop a device that is capable of enhancing user comfort during travel by dynamically managing noise cancellation with ergonomic support, thermal regulation and relaxation for ensuring safety, wellness and uninterrupted rest.

[0009] Another object of the present invention is to develop a device that is capable of minimizing disruptive environmental noise through adaptive cancellation techniques for creating a calm auditory environment that enhances relaxation, reduces travel fatigue and improves user focus without requiring external accessories or manual sound adjustments.

[0010] Another object of the present invention is to develop a device that is capable of providing an adaptive support means that automatically conforms to the user’s anatomy, ensuring optimal alignment, reducing muscular strain and preventing discomfort while maintaining long-term ergonomics for both adults and children under varying postural conditions.

[0011] Another object of the present invention is to develop a device that is capable of dynamically adjusting thermal balance to ensure consistent user comfort, minimize thermal stress and support individual’s sensitive to sudden temperature changes across diverse environmental conditions.

[0018] These and other features, aspects, and advantages of the present invention will become better understood with regard to the following description, appended claims, and accompanying drawings where:
Figure 1 illustrates an isometric view of a travel neck support device with noise reduction.

DETAILED DESCRIPTION OF THE INVENTION

[0019] The present invention relates to a travel neck support device with noise reduction that is capable of suppressing unwanted sounds and providing ergonomic support with soothing therapeutic effects to enhance relaxation, improve circulation and also offer automatic eye shielding from light for improving sleep quality, simplifying travel fatigue management and enhancing in-transit rest quality.

[0020] Referring to Figure 1, an isometric view of a travel neck support device with noise reduction is illustrated, comprising a pillow structure 101, a plurality of microphones 102 embedded around the pillow structure 101, a retractable headphone 103 housed with the pillow structure 101, a camera 104 mounted on the structure 101, a plurality of vibration motors 105 embedded along the sides and back of the pillow structure 101 and a pair of eye-covering members 106 connected to one or more elongated support member 107 that are housed within a concealed compartment 108 of the pillow structure 101.

[0021] The device disclosed herein comprises of a pillow structure 101 configured to provide ergonomic support to a user’s neck by focusing on proper spinal alignment and targeted comfort. The pillow structure 101 is characterized by a contoured form, including a recessed central cavity where the head naturally fits, flanked by gently raised side that support the neck and maintain the cervical curve. This design ensures the neck is neither tilted too high nor allowed to sink too low, preventing strain on vertebral joints and surrounding muscles. The material use includes but not limited to memory foam or latex for adaptive contouring, microfiber or cotton for softness and breathable mesh or cooling gel layers for ventilation. These materials combine to ensure durability, comfort, temperature regulation and precise ergonomic neck support that stabilizes the cervical spine during sleep, reducing risks of stiffness and facilitating healthier rest cycles.

[0022] An input means is installed on the pillow structure 101 to facilitate the user to provide input commands for control of operations. The input means mentioned herein includes but not limited to a user-interface that is wirelessly linked with the pillow structure 101, a physical switch embedded on the pillow structure 101 and voice command capability.

[0023] In a preferred embodiment of the present invention, the user access the user interface installed within the computing unit to facilitate user by providing operative commands for control of operations. The user interacts with the interface through a touch screen, keyboard or other input methods available on the computing unit. The computing unit mentioned herein includes, but is not limited to smartphone, tablet or laptop that comprises a processor that receives data from a controller of the device, stores, processes and retrieves the output in order to display on the computing unit.

[0024] A wireless communication module for establishing a wireless connection between the controller and a computing unit is inbuilt within the controller. The communication module used herein includes, but not limited to Wi-Fi (Wireless Fidelity) module, Bluetooth module, GSM (Global System for Mobile Communication) module. The communication module used herein is preferably a Wi-Fi module that is a hardware component that enables the controller to connect wirelessly with the computing unit. The Wi-Fi module works by utilizing radio waves to transmit and receive data over short distances. The core functionality relies on the IEEE 802.11 standards, which define the protocols for wireless local area networking (WLAN). Once connected, the module allows the controller to send and receive data through data packets.

[0025] In another embodiment of the present invention, a physical switch is integrated into the pillow structure 101 to provide a straightforward, tangible means to activate the device, facilitating users who prefer immediate adjustments. The physical switch works as a simple yet reliable control arrangement, consisting of three core components: an actuator button, a conductive contacts and a connection to the pillow’s controller. When the user presses the actuator, the applied force moves an internal spring arrangement that momentarily bridges two conductive contacts beneath. This completes an electrical circuit, sending a low voltage signal directly to the controller. Depending on the programmed, the duration or sequence of presses (single, double, or long press) translates into specific operational commands such as toggling power, switching temperature levels or cycling through massage patterns.

[0026] In yet another embodiment of the present invention, the user is able to provide voice commands regarding operative commands for control of operations. A microphone is used herein for providing voice command, which is connected to an internal voice recognition module that continuously listens for commands. The microphone works by converting sound waves into electrical signals. When a sound is made, creates vibrations in the air, which are perceived as sound waves. The microphone has a diaphragm of thin membrane, attached to a small coil of wire, behind this coil a strong permanent magnet that creates a magnetic field. When sound waves reach the microphone, they cause the diaphragm to vibrate. These vibrations move the attached coil back and forth within the magnetic field, generating an electrical current that mirrors the pattern of the sound wave. The resulting electrical signal is a representation of the original sound and transmitted to the controller to processes the user's command and interprets the command for control of operations.

[0027] At least one imaging unit is integrated with the pillow structure 101 to detect the dimensions of the user’s neck in order to provide highly customized support. The imaging unit includes a camera 104 operatively coupled with an infrared (IR) sensor and an ultrasonic sensor to determine neck dimensions. The camera 104 receives activation signal from the controller, to detect neck dimensions. The camera 104 comprises of an image capturing module including a set of lenses that captures multiple high-resolution images of the user’ neck to determine dimension, then the captured images are stored within memory of the imaging unit in form of an optical data. The imaging unit incorporates a processor that is fed with an artificial intelligence protocol which operates by following a set of predefined instructions to process optical data and perform tasks autonomously. Initially, captured images are collected and input into a database, which then employs protocol to analyze and interpret the optical data. The processor of the imaging unit via the artificial intelligence protocol processes the optical data and extracts the required data from the captured images. The extracted data is further converted into digital pulses and bits and transmits to the controller for analysis.

[0028] The infrared (IR) sensor disclosed above enhance the precision of neck measurement by detecting distance, shape and contour. The infrared (IR) sensor by using an emitter diode to generate a focused beam of infrared light directed toward the user’s neck, while optical filters restrict unwanted wavelengths to ensure beam purity. A collimating lens aligns and narrows the beam, maintaining accuracy over short distances. Once the emitted beam reflects off the neck surface, passes back through a receiving lens that concentrates the returning light onto a photodetector. The photodetector converts this reflected light into electrical signals correspond to surface distance and geometry. These signals are routed through an amplifier and signal processor, where noise is minimized and wave patterns are analyzed for depth mapping. Finally, the processed data is relayed to the controller to determine precise distance, shape and contour recognition.

[0029] The ultrasonic sensor disclosed above emits high frequency sound waves through a transmitter; the sound waves propagating through air until contacting the surface of the user’s neck. Upon striking the surface, the sound waves are reflected back as echoes and received by a receiver integrated within the ultrasonic sensor. The ultrasonic sensor determines a time interval between transmission and reception of the sound waves and by utilizing the speed of sound in air, calculates a distance between the pillow structure 101 and the neck surface with high accuracy. The calculated distance data is transmitted to the controller to integrate the ultrasonic distance data with the visual data obtained from the camera 104. Synchronization and cross validation of the data from the camera 104 and the ultrasonic sensor for enhance reliability in accurately detecting the dimension, shape and contour of the user’s neck.

[0030] At least one inflatable chamber is embedded within the pillow structure 101 to dynamically conform to the user’s neck dimensions and provide tailored ergonomic support. The inflatable chamber is equipped with a pump and pressure sensors that regulate airflow in and out of the chamber by continuously monitoring internal pressure, providing accurate feedback to ensure precise and consistent inflation. Once the neck profile is determined by analysing neck’s dimensions, the controller processes this data against pre-defined ergonomic pressure profiles stored in a database and actuates the pump to either inflate or deflate the chamber to achieve the optimal level of firmness and contouring. The pump consists of a miniature electric motor that drives a diaphragm housed within the pump casing. When the motor rotates and moves the diaphragm back and forth, creating alternating low-pressure and high-pressure zones. This motion draws ambient air into the pump through an inlet equipped with a one way valve, ensuring air only flows in. As the diaphragm compresses, the air is forced out through an outlet valve into the inflatable chamber, steadily increasing internal pressure, enabling consistent chamber inflation. The controller is configured to adapt to different user categories by analyzing pressure profiles defined for specific ergonomic and safety requirements. In a first profile, the chamber inflates to a softer pressure level tailored for children, ensuring gentle cushioning and safe cervical support without imposing excessive force on the developing structure 101. In a second profile, the chamber inflates to a firmer pressure level suitable for adults, providing stable and reinforced support necessary to maintain spinal alignment under greater body weight and pressure conditions.

[0031] Additionally, the chamber incorporates a protective pressure profile in which automatically deflates upon detection of excessive pressure exerted on the user’s neck, as determined through real time feedback from the integrated pressure sensors that work by converting air pressure within the chamber into an electrical signal. At core is a diaphragm element that flexes or deforms in response to changes in air pressure. This movement is transmitted to a piezoresistive element mounted on the diaphragm, which alters electrical resistance as the diaphragm flexes. The change in resistance is then converted into a proportional voltage signal by a Wheatstone bridge circuit, ensuring sensitivity and accuracy. This raw signal is next amplified by a signal conditioning unit, which filters noise and stabilizes the output for reliable performance. The conditioned signal is then transmitted to the controller, which interprets the pressure in real time, ensuring precise control during automatic deflation to prevent over inflation, restrict undue compression and eliminate the risk of circulatory or muscular strain, for ensuring both safety and long term comfort.

[0032] The microphones 102 are embedded at different locations on the pillow structure 101, to capture ambient sounds from multiple directions with clarity and precision. The microphone 102 function as an acoustic transducer, converting surrounding sound waves into electrical signals. By positioning the microphones 102 in a distributed array, to achieve directional sensitivity, enabling to distinguish the environmental noise. The multi directional arrangement enhances sound accuracy by reducing blind spots and balancing inputs across different positions.

[0033] A digital signal processing (DSP) unit is operatively coupled to the microphones 102 functions as a dynamic noise mitigation and management, to enhance the user’s environment by cancelling disruptive ambient sounds. When the plurality of microphones 102 captures sound signals from multiple directions, these acoustic signals are first converted into electrical representations and forwarded to the DSP unit for processing. Within the DSP, at least one adaptive filter selected from a feedforward filter, a feedback filter or a hybrid combining both is employed to analyze the incoming sound in terms of frequency, phase and waveform characteristics. Based on this analysis, the adaptive filter generates an inverse sound signal, which, when output through dedicated mini-transducers integrated in the pillow, overlaps with the original noise waveforms and cancels them using the principle of destructive interference. This provides the foundation for real-time active noise cancellation. Simultaneously, a controller within the DSP continuously monitors the intensity and spectral distribution of the captured noise and dynamically adjusts the inverse sound/cancellation levels to maintain optimal silence, even as the surrounding noise environment changes.

[0034] To further enhance accuracy and minimize residual sound leakage, the DSP unit utilizes a real-time adaptive noise cancellation protocol, which is configured as LMS (Least Mean Square), NLMS (Normalized LMS), RLS (Recursive Least Square), Kalman filter or a combination thereof. These iteratively adapt filter coefficients, constantly refining the inverse signal to match even subtle variations in ambient noise with extremely high precision. For example, LMS and NLMS protocols adjust signal cancellation efficiently for consistent noise patterns like snoring, while RLS and Kalman filters provide faster convergence and superior accuracy under rapidly changing or more complex noise conditions. This multi-layered processing ensures that both low-frequency disturbances and higher-frequency interruptions are effectively suppressed. The synchronization of microphones 102, adaptive filters, dynamic controllers and real-time adaptive noise cancellation protocol allows the DSP unit to maintain an acoustically optimized environment for the user.

[0035] A retractable headphone 103 is housed within the pillow structure 101 to deliver personalized noise cancellation while ensuring ease of use for ensuring both comfort and acoustic precision for the user. The user accesses the headphone 103 manually by hand, gently pulling from housing within the pillow structure 101 and placing in the ear for active use. This is supported by a spring retraction assembly installed into the pillow structure 101, consisting of a compact coiled spring and guiding channels that ensure smooth extension when the earphone is pulled out the spool rotates, unwinding the spring and storing energy within coils. The guiding track ensures the cable or earphone moves smoothly without tangling and provides effortless retraction once released after use. During extension, a locking unit embedded within the earphones engages, maintaining the headphone 103 in an extended and stable position to prevent accidental withdrawal during wear. The locking unit consists of a latch, a notched retention area and a release arrangement. When the headphone 103 is pulled outward, the latch, usually spring loaded, slides into the notched retention area along housing or cable guide of the headphone 103, creating a secure hold that resists the pullback force of the retraction spring. This ensures that the earphones remain stable while in use without unintended withdrawal. The latch stays engaged until the user applies a deliberate action, such as pressing or slightly twisting the release arrangement, which shifts the latch out of the notch. Once disengaged, the spring retraction assembly to withdraw the headphone 103 back into the pillow structure 101, keeping neatly stored, tangle free and protected. The retractable headphone 103 configured to receive the inverse sound signal generated by the DSP unit, the headphone 103 emits corresponding anti-noise to effectively cancel out unwanted ambient sounds, delivering a quiet and calming environment. The retractable headphone 103 is integrated with ear-cushion seal, which is specifically adapted to balance internal ear pressure with external cabin pressure. This is particularly useful in environments such as aircraft or high-altitude travel, where sudden changes in external pressure cause discomfort; the ear-cushion seal dynamically adjusts internal chamber to equalize pressure and maintain a natural, comfortable feel for the eardrum.

[0036] The headphone 103 also comprises an acoustic damping layer, positioned within the earphone’s body to reduce sound leakage. This ensures that generated anti-noise or audio signals remain confined within the ear canal, improving noise cancellation effectiveness while preventing sound spill-over that disturb others nearby. The controller is operatively coupled with both the ear-cushion seal and the acoustic damping layer, orchestrating real-time adjustments to pressure levels and acoustic properties based on environmental conditions and noise profiles. For example, the controller increase damping during louder external conditions to maximize isolation, or fine-tune the cushion’s pressure balance when detecting fluctuations in cabin air pressure. This real-time adaptability ensures both safety and comfort by reducing stress on the eardrum, while also preserving high-fidelity noise cancellation performance. This provides protection against ambient disturbances combined with stable ergonomic performance for restful and undisturbed use in diverse environments.

[0037] A sound filtering module is integrated within the pillow structure 101 to regulate the auditory experience by controlling how sounds reach the user, adapting dynamically to both head orientation and environmental conditions. When the user turns their head to one side, the module, operatively coupled with orientation information from the pillow, selectively permits sound from that side to pass through the headphone 103, ensuring important audio signals such as a conversation partner’s voice or an alert remain clear and intelligible. During this process, the module adjusts volume levels and tonal balance to optimize clarity, compensating for muffled frequencies or reduced spatial awareness caused by the pillow’s physical contact. Simultaneously, the module applies active noise cancellation protocols to suppress ambient sounds originating from other directions, ensuring that surrounding disturbances such as snoring, traffic or general background noise are neutralized through inverse sound wave emission. By combining sound permeability in one direction with noise suppression in others, the sound filtering module creates a controlled acoustic bubble tailored to the user’s real-time environment. This dual operation maintains situational awareness where necessary while safeguarding uninterrupted rest, effectively merging comfort, safety and performance into a single adaptive audio management.

[0038] The pillow structure 101 features an AI-focused listening mode developed to enhance communication and improve selective hearing in noisy environments. In this mode, the array of microphones 102 embedded around the pillow structure 101 not only captures surrounding sounds but also assists in selecting the appropriate operating mode based on the acoustic context, helping to decide whether to maintain AI-focused listening, switch to a general ambient-awareness mode, multilingual communication or engage noise suppression by dynamically adapting to the user’s situation, whether resting in a quiet room, conversing in a lively setting or filtering out disruptive night time noises. Through advanced AI-driven signal processing protocols that identify and isolate the target speaker’s voice from background noise. The mode distinguishes the voice by recognizing unique acoustic patterns such as vocal pitch, direction of origin, and speech consistency, allowing to separate the desired signal even in the presence of overlapping sounds like chatter, snoring, or environmental disturbances. Once the desired voice is isolated, amplified and adjusted in real time for clarity through dynamic equalization, ensuring speech frequencies are emphasized while unwanted background sounds are suppressed. The processed and enhanced voice signal is then transmitted to the retractable headphone 103, providing the user with clear, intelligible audio while minimizing distraction from other ambient noise sources.

[0039] The device also features a multilingual communication mode, developed to act as real-time language bridge for the user. In this mode, the microphones 102 capture speech spoken in a foreign language, ensuring clarity even in noisy environments through directional filtering and background suppression. The captured voice data is then transmitted to an AI translation module, which processes the input, identifies the language, and translates into the user’s preferred language almost instantly. The translated output is delivered back to the user through the retractable headphone 103, enabling smooth and natural comprehension without the need for external devices. To extend communication further, the mode also processes the user’s spoken response: their voice input is captured, translated by the AI module into the foreign listener’s language, and optionally displayed visually on the interface or transmitted for playback, depending on the setup. This mode transforms the device into a personal communication assistant, enhancing accessibility, travel convenience and social interaction in cross-cultural environments.

[0040] The wireless communication module is also developed to interface with a vehicle announcement means to ensure that important information reaches the user without disrupting comfort or rest. When the user is present in the vehicle, the module connects to the on-board announcement means via standard wireless protocols such as Bluetooth, Wi-Fi, or other vehicle-compatible signals, creating a direct communication link. Once connected, the module employs a voice recognition protocol to filter through all broadcast announcements, distinguishing those specifically relevant to the user such as seat number, stop location, emergency instructions, or personalized service updates from general nonessential messages. This selective filtering prevents the user from being overwhelmed by constant announcements while still guaranteeing that critical or user-specific information is not missed. After processing and isolating the relevant announcement, the module transmits the clear, filtered audio directly to the headphone 103, ensuring that the user hears the message in a private, distraction-free manner without disturbing nearby passengers. This enhances convenience, comfort and safety during travel.

[0041] A barometric pressure sensor is arranged within the pillow structure 101 to continuously monitor atmospheric pressure levels in the user’s environment, ensuring both comfort and safety, particularly during travel in aircrafts, high-altitude terrains or sealed cabin spaces. The barometric pressure sensor works by using a flexible diaphragm sealed over a reference chamber, which deforms in response to external air pressure changes. This deformation applies force to an attached strain element normally a piezoresistive that alters electrical characteristics based on the diaphragm’s movement. These variations are routed into a Wheatstone bridge or capacitive detection circuit, converting the displacement into an analog electrical signal proportional to pressure. The signal then passes through an amplifier and signal conditioning stage, where stabilized, filtered and adjusted for ambient variations, then transmitted to the controller to determine sudden variations in pressure such as in rapid altitude changes or cabin depressurization, generates an alert that delivered to the user via the retractable headphone 103 or on input means. This functional alert ensures the user is quickly aware of pressure anomalies, allowing timely corrective action (such as adjusting posture or pressure balance in the ear-cushion seal).

[0042] A temperature regulation unit is integrated with the pillow structure 101 to provide individualized thermal comfort by heating or cooling the pillow surface according to the user’s preference. The temperature regulation unit comprises a Peltier module for ensuring even distribution of warmth or cooling across the contact area and operatively coupled to a temperature sensor for monitoring the surface temperature of the pillow in real time. The temperature sensor captures infrared radiation emitted by pillow surface. The sensor comprises a thermopile with an integrated lens or filter adapted to collect and focus the infrared radiation onto a sensing element. The thermopile is operable to absorb the infrared radiation and generate a voltage signal through the Seebeck effect, the voltage being proportional to the ambient temperature.

[0043] The generated analog voltage signal is amplified and converted into a corresponding digital signal by an analog-to-digital converter (ADC), the digital signal being transmitted to the controller, which cross-references this data with the user’s pre-set preferences such as cooling for hot environments or gentle heating for colder conditions and dynamically regulates the electrical current passing through the Peltier module. The Peltier module is configured to operate on a thermoelectric effect and comprises pairs of semiconductor materials arranged between two ceramic plates. Upon application of a direct current (DC) electrical signal, electrons and holes are configured to move through the semiconductors for transferring heat from one side of the module to the other and producing a temperature differential such that one side becomes cold to absorb heat and the opposite side becomes hot to dissipate heat. A heat sink is coupled to the hot side and is configured to dissipate excess heat to maintain stable operation. A gel layer is arranged in thermal communication with the Peltier module, the Peltier module being further configured to transfer thermal energy to or from the gel layer for regulating the surface temperature of the pillow structure 101. In cooling mode, the Peltier module is configured to draw heat from the gel layer and dissipate the heat externally and in heating mode, the Peltier module is configured to add heat to the gel layer to increase the surface temperature. The gel layer is adapted to distribute the transferred thermal energy evenly across a skin-contact area, for ensuring rapid localized thermal adjustment, reducing thermal discomfort and preventing temperature-related physiological triggers.

[0044] A massaging unit is integrated with the pillow structure 101 configured to enhance comfort and relaxation by delivering rhythmic vibration cycles. The massaging unit consists of a plurality of vibration motors 105 embedded along the sides and back portions of the pillow structure 101, targeting areas most closely aligned with the user’s neck, shoulders and upper spine to generate rhythmic vibration patterns for relieving muscle tension. The user access the input means to provide command for initiation of massaging, upon which the controller actuates the plurality of vibration motors 105 to produce rhythmic oscillation patterns that help ease muscle strain. The vibration motors 105 consist of a rotary shaft fitted with an off-center weight. As the motor 105 rotates, the uneven distribution of the weight generates vibrations, which are transferred to the pillow structure 101 and perceived by the user.

[0045] These vibrations help soothe muscle tension, stimulate circulation, relieve stiffness and enhance overall comfort. The controller is operatively coupled with the motors to regulate vibration intensity, duration and pattern sequence. The controller processes either direct user commands or pre-configured therapeutic modes stored within the database, ensuring massage cycles are tailored to user preferences or specific wellness outcomes. For instance, the controller alternate between wave-like rolling patterns for calming relaxation or steady pulsed rhythms for targeted tension relief, ensuring even distribution of vibrations, preventing discomfort caused by concentrated pressure while delivering therapeutic comfort.

[0046] An automated eye mask is integrated with the pillow structure 101 to function as a comfort and wellness feature that deploys only when needed, ensuring both functionality and aesthetic integration. The automated eye mask includes a pair of eye-covering members 106 connected to one or more elongated support member 107 that are pivotally coupled and housed within a concealed compartment 108 of the pillow structure 101. The user access the input means to provide command for deploying the automated eye mask, then the controller actuates the one or more elongated support member 107 to articulate smoothly, enabling precise extension from the concealed compartment 108 and positioning of the eye-covering members 106 from their stowed location to over the user’s eyes.

[0047] The elongated support member 107 consists of nested tubular sections that slide within each other, connected to a pneumatic unit. Which includes an air compressor, a cylinder with a piston and solenoid valve. The air compressor generates compressed air, which passes through a solenoid valve and enters into the air cylinder. The air pressure inside the cylinder causes the piston to push the rods outward, causing multiple nested tubular sections to extend, for deploying the eye-covering members 106 from their stored position to align over the user’s eyes. Simultaneously, the controller actuates a pivot joint installed between the support members 107 to enable multi-directional articulation of the eye-covering member 106, allowing precise movement in various directions for accurate alignment of the eye-covering members 106 over the user’s eyes. The pivot joint consists of a spherical ball enclosed within a socket and driven by multiple small electric motors, positioned orthogonally around the joint.

[0048] Each motor is linked to the socket via gear drive, allowing to apply torque to tilt or rotate the ball along specific axes. When the motor is activated by the controller, drives the gear drive to push or pull against the ball’s surface, causing the ball to pivot or rotate within the socket to provide directional flexibility to the member 106, permitting precise adjustment for proper alignment of the eye-covering members 106 over the user’s eye to cover to block external light, for creating an optimal sleep environment that promotes rest and relaxation. When use is complete or the user issues a stowing command, the same support member 107 operate in reverse, guiding the eye-covering members 106 back into the concealed compartment 108 and preserves the ergonomic contour of the pillow structure 101 and avoiding any disturbance during normal head or neck use.

[0049] The present invention also provides a method for enhancing user comfort and reducing noise during travel comprising multiple steps. First, ambient sounds are acquired by plurality of microphones 102 embedded in the pillow structure 101 and routed to the DSP unit, where at least one adaptive filter processes the data to generate an inverse noise cancellation signal. This signal is transmitted through the retractable headphone 103, effectively suppressing unwanted external noise and creating a calmer environment for rest. Simultaneously, neck pressure is monitored using embedded pressure sensors, allowing inflatable chambers within the pillow structure 101 to either automatically inflated or deflated under controller regulation for a personalized ergonomic fit. The barometric sensor detects sudden cabin pressure variations, prompting to generate alerts through haptic feedback or the user interface, ensuring user awareness and safety. Thermal comfort is maintained by the Peltier element, which selectively heats or cools the pillow surface in response to user commands. For added relaxation, vibration motors embedded within the structure 101 deliver soothing massage cycles, while the automated eye mask extended to shield the eyes from surrounding light. Lastly, the wireless communication unit and an AI-based translation module transmit filtered announcements and real-time translations through the headphones 103, providing relevant information while maintaining uninterrupted comfort.
