Description:SYSTEM FOR CONTROLLING VOLUME IN AUDIO DEVICE
TECHNICAL FIELD
[0001] The Present disclosure relates to a system and a method for controlling volume in an audio device.
BACKGROUND 5
[0002] Generally, a rider of a vehicle has his/her device such as mobile phone and a headphone paired so that he/she can receive calls or listen to songs or any audio file while riding the vehicle. If the rider is travelling on highway with a low volume, the rider tends to increase the sound by pressing the volume adjust button. On the other hand, if the rider is travelling with a high 10 volume in the city area, the rider tends to reduce his device volume to address the crowd or to hear any voice coming from the surrounding environment. Whenever the rider wants to adjust the volume of the device, the rider has to manually increase or decrease volume through volume adjust buttons provided in the mobile phone. Such manual adjustment of volume may affect 15 rider’s concentration during riding of the vehicle which may cause an accident. Also, the overall auditory experience of the rider is affected, since the rider has to manually adjust the volume of the device based on surrounding noise which is undesirable.
[0003] Generally, in motorcycles, engine noise can be substantial, making it 20 difficult for riders or drivers to hear audio from communication devices or entertainment systems clearly. This problem becomes more pronounced at higher speeds where engine noise tends to increase. Traditional systems may not adequately compensate for these fluctuations in engine noise, leading to an unsatisfactory auditory experience. 25
[0004] Conventionally technical challenges is the interference caused by engine noise with audio output. Engine noise can vary greatly depending on factors such as engine speed, vehicle type, and environmental conditions. This variability makes it difficult to maintain consistent audio quality, leading to reduced clarity and comprehension for communication systems and 30

entertainment devices. Vehicles operate in dynamic environments where conditions such as speed, road surface, and wind can change rapidly. Conventional audio systems often lack the adaptability to adjust audio output in real-time according to these changing conditions. As a result, users may experience discomfort or distraction due to sudden changes in audio volume 5 or clarity. [0005] Generally maintaining clear communication and entertainment options is essential for user safety and comfort, especially in scenarios where riders or drivers rely on audio cues or communication with passengers or other vehicles. Any degradation in audio quality due to engine noise 10 interference can compromise safety by reducing situational awareness or causing distractions. Providing an optimal user experience entails ensuring that audio output remains consistent and comfortable across various driving conditions. This includes addressing challenges such as adjusting audio volume appropriately at different engine speeds to compensate for changes in 15 ambient noise levels without causing discomfort or distraction to the user. Effective integration with existing vehicle systems, such as instrument clusters and communication devices, is crucial for seamless operation and user accessibility. Ensuring compatibility and interoperability with these systems while delivering the desired audio enhancements presents a technical 20 challenge that needs to be addressed. Implementing real-time adjustments to audio output based on engine speed requires efficient processing and communication between various components within the vehicle's ecosystem. Achieving smooth transitions and accurate volume adjustments without introducing delays or glitches is a technical challenge that needed to be 25 overcome.
[0006] In conventional system the users manually adjust the volume of their audio devices based on perceived changes in engine noise. While this method allows for some control over audio output, it is subjective and may not always be timely or accurate. Users may forget to adjust the volume, leading to 30 periods of discomfort or reduced clarity. Additionally, manual adjustment can be distracting, especially during critical moments of driving or riding.
4
[0007] Conventionally ANC systems use microphones and speakers to generate anti-noise signals that cancel out engine noise. While effective for reducing steady-state low-frequency noise, ANC systems may struggle to adapt to rapidly changing noise environments, such as those encountered in vehicles. They may also be less effective at cancelling out higher frequency 5 noise or sudden transient sounds, leading to incomplete noise reduction.
[0008] Traditionally some audio systems implement fixed volume thresholds based on vehicle speed. For example, the volume may increase above a certain speed threshold to compensate for engine noise. However, this approach lacks adaptability to individual preferences and environmental 10 conditions. It may result in audio output that is either too loud or too quiet for the user's comfort, especially in varying driving conditions.
[0009] Traditional methods like Passive methods such as adding insulation materials to the vehicle's interior or using noise-reducing helmets aim to attenuate engine noise reaching the user's ears. While effective to some 15 extent, passive sound insulation may add weight to the vehicle, reduce interior space, and be less effective at higher speeds or with high-frequency noise. Additionally, it does not address the need for dynamic adjustments to audio output based on real-time conditions.
[00010] Conventionally some audio systems apply fixed equalization 20 settings to compensate for engine noise. For example, boosting certain frequencies associated with speech or music to enhance clarity. However, fixed equalization settings may not be suitable for all users or driving conditions. They may also introduce distortion or unnatural sound quality, especially when applied indiscriminately across different audio sources. 25
[00011] Volume compression techniques aim to reduce the dynamic range of audio signals, effectively reducing the difference in volume between quiet and loud passages. While this can help maintain overall consistency in audio output, it may also reduce the perceived clarity and impact of audio signals, particularly in music or speech with varying dynamics. 30
[00012] Thus, there is a need in the art for a system which can address at least the aforementioned problems.
5
[00013] Further limitations and disadvantages of conventional and traditional approaches will become apparent to one of skill in the art, through comparison of described systems with some aspects of the present disclosure, as set forth in the remainder of the present application and with reference to the drawings. 5

[00035] The present disclosure generally relates to an audio device and particularly relates to a system for controlling volume in the audio device. In the ensuing exemplary embodiments, the vehicle 200 is a motorcycle. However, it is contemplated that the disclosure in the present disclosure may 25 be applied to any automobile like a scooter or any other saddle type vehicle capable of accommodating the present subject matter without defeating the scope of the present disclosure.
[00036] In an embodiment, the vehicle may be a two-wheeled vehicle, a three-wheeled vehicle, a four-wheeled vehicle, or a multi-wheeled vehicle. 30 The vehicle may be powered by an internal combustion engine or an electric
9
motor through one or more batteries or a hybrid-electric motor as per requirement. It should be understood that the scope of present disclosure is not limited to the illustrated two-wheeled vehicle having the internal combustion engine. [00037] Figure 1 illustrates a block diagram of the system 100 for controlling 5 audio in the audio device, in accordance with an embodiment of the present disclosure. The system 100 comprises a control unit 102 which is communicatively coupled to a communication device 104 of a rider of a vehicle 200 (shown in figure 2). In an embodiment, the communication device 104 is communicatively coupled to the control unit 102 via wireless 10 communication. In an embodiment, the control unit 102 is one of a vehicle control unit or a dedicated control unit. In another embodiment, the control unit 102 is a Speed Dependent Volume Control (SDVC) unit 106 of the communication device 104. In an embodiment, the SDVC is a technique to control volume of an audio device 114. The SDVC is a feature incorporated 15 in the communication device 104. In an embodiment, the communication device 104 is at least one of a mobile phone, a tablet or an electronic device which is used for communication by the rider of the vehicle 200.
[00038] Further, the vehicle 200 includes an instrument cluster 112 disposed in the vehicle 200. The instrument cluster 112 is communicatively coupled to 20 the control unit 102. In an embodiment, the instrument is also communicatively coupled to the communication device 104. The instrument cluster 112 is adapted to display data related to the vehicle 200. Further, the vehicle 200 includes an engine control unit (ECU). The engine control unit (ECU) is responsible for monitoring and regulating various aspects of the 25 vehicle's engine operation, with a primary focus on determining engine speed, controlling fuel injection timing, adjusting ignition timing, and managing other parameters crucial for optimal engine performance and efficiency. Further, the vehicle 200 includes an engine speed sensor 110 which is communicatively coupled to the control unit 102 through the engine control 30 unit 108. The engine speed sensor 110 is configured to detect the speed of the engine and communicate the engine speed to the control unit 102. In an
10
embodiment the engine speed sensor 110 monitors the crankshaft's rotational speed. The engine speed sensor 110 may be positioned in proximity to the crankshaft or flywheel. The engine speed sensor 110 may include a Magnetic Inductive Sensor, a hall effect sensor, or an optical sensor. The control unit 102 is configured to receive the engine speed from the engine speed sensor 5 110 disposed in the vehicle 200. [00039] Further, the audio device 114 is communicatively coupled to the control unit 102. In an embodiment, the audio device 114 can be the communication device 104 and/or a wearable audio device (not shown) such as a wireless or wired earphone, a wireless or wired headphone etc. The 10 control unit 102 is configured to receive a volume level of the audio device 114.Once the control unit 102 receives the volume level of the audio device114, the control unit 102 is configured to determine an engine speed rangecorresponding to the volume level. Further, the control unit 102 is configuredto adjust the volume level of the audio in the audio device 114 corresponding 15 to the Engine speed, when the engine speed deviates from the determined speed range. In an embodiment, the control unit 102 is configured to adjust the volume level of the audio by increasing the volume level in the audio device 114, when the engine speed increases from the predetermined speed range corresponding to the previous volume level of the audio. In an 20 embodiment, the control unit 102 gradually increases the volume level of the audio to the corresponding volume range of the new predetermined engine speed range.
[00040] In another embodiment, the control unit 102 is configured to adjust the volume level of the audio by decreasing the volume level in the audio 25 device 114, when the engine speed decreases from the predetermined speed range corresponding to the previous volume level of the audio. In an embodiment, the control unit 102 gradually decreases the volume level of the audio to the corresponding volume range of the new predetermined engine speed range. In an embodiment, the increase, or the decrease in the volume 30 level in the audio device 114 is displayed on the instrument cluster 112.
11
[00041] In an embodiment, the control unit 102 is configured to adjust the volume level of the audio in the audio device 114 corresponding to the engine speed at a gradual rate with a buffer of a preset time duration. In an exemplary embodiment, the volume changes gradually from 10 to 5 when it is decreasing or from 5 to 10 when it is increasing. The volume gradually reduces from 10 5 to 9, 9 to 8, 8 to 7, 7 to 6 and then 6 to 5. In a non-limiting example, the gradual variation of the volume occurs within a time period of 2 seconds. Such a configuration of the system mitigates sudden volume drop in the audio device 114, which may feel problematic to the rider and also may distract the rider during riding of the vehicle 200. In an embodiment, the rider may 10 modify the rate of volume reduction and the time required for volume reduction as per requirement.

[00043] Figure 3 illustrates a method flow diagram of a method for 5 controlling audio in an audio device, in accordance with an embodiment of the present disclosure. The control unit 102 is communicatively coupled to the communication device 104 and the engine speed sensor 110. At step 302, the control unit 102 receives the engine speed from the engine speed sensor 110 disposed in the vehicle 200. In an embodiment, the control unit 102 is 10 one of the vehicle control units, the dedicated control unit, and the Speed Dependent Volume Control (SDVC) unit 106 of the communication device 104.In an embodiment, the communication device 104 is at least one of themobile phone, the tablet or the electronic device which is used forcommunication by the rider of the vehicle 200. The control unit 102 is 15 configured to receive the engine speed from the sensor 110 disposed in the vehicle 200. At step 304, the control unit 102 receives the volume level of the audio device 114. In an embodiment, the audio device 114 is at least one of a communication device 104 and a wearable audio device. Once the control unit 102 receives the volume level of the audio device 114, at step 306, the 20 control unit 102 determines an engine speed range corresponding to the volume level. Further, at step 308, the control unit 102 adjusts, the volume level of the audio in the audio device 114 corresponding to the engine speed, when the engine speed deviates from the determined speed range. In an embodiment, as explained above, the control unit 102 adjust the volume level 25 of the audio in the audio device 114 corresponding to the engine speed at a gradual rate with a buffer of a preset time duration. In another embodiment, the control unit 102 adjust the volume level of the audio by increasing the volume level in the audio device 114, when the engine speed being greater than the determined speed range. In an alternate embodiment, the control unit 30 102 adjust the volume level of the audio by decreasing the volume level in the audio device 114, when the engine speed being lesser than the determined
14
speed range. In an embodiment, the communication device 104 is communicatively coupled to the instrument cluster 112 of the vehicle. The instrument cluster 112 is adapted to display data related to the vehicle 200. In an embodiment, the increase, or the decrease in the volume level in the audio device 114 and the speed of the vehicle 200 is displayed on the instrument 5 cluster 112. [00044] Figures 4A, 4B and 4C are flow diagrams of the method depicting controlling audio in an audio device, in accordance with an exemplary embodiment of the present disclosure.
[00045] At step 402, the ignition key is ON by the rider of the vehicle 200. 10 At step 404, after the ignition key is ON, the communication device 104 is communicatively coupled to the instrument cluster 112. In an embodiment the communication device 104 is at least one of the mobile phone, the tablet and the electronic device which is used for communication by the rider of the vehicle 200. At step 406, once the communication device 104 is 15 communicatively coupled to the instrument cluster 112, the control unit 102, checks the status of the SDVC unit 106 of the communication device 104 at the application setting of the communication device 104. If the SDVC unit 106 is disabled, at step 408, the control unit 102 displays a message “SDVC is Disabled” on the instrument cluster 112 of the vehicle 200. If the SDVC 20 unit 106 is enabled, at step 410, the control unit 102 displays a message “SDVC is Enabled” on the instrument cluster 112 of the vehicle 200. In another embodiment when the control unit 102 is an SDVC unit 106. In such case, as per the setting chosen by the rider, at step 410, the SDVC unit 106 of the communication device 104 is configured to displays “SDVC is Enabled” 25 on the instrument cluster 112 of the vehicle 200 if the rider has enabled the SDVC unit 106. If the rider has disabled the SDVC unit 106, at step 408, then the communication device 104 is configured to displays “SDVC is Enabled” on the instrument cluster 112 of the vehicle 200.
[00046] At step 402, the ignition key is turned ON by the rider of the vehicle 30 200.At step 412, after the ignition key is ON, the control unit 102 receives
15
the engine speed from the engine speed sensor 110 disposed in the vehicle 200.At step 414, the control unit 102 checks for an error in the Engine controlunit 108 before using the data received from the Engine control unit 108 toeliminate the possibility of wrong data being received from the Engine controlunit 108. If the error is detected in the Engine control unit 108 by the control5 unit 102, then at step 416, the control unit 102 will display a message “enginespeed sensor error” on the instrument cluster 112 of the vehicle 200. If theerror is not detected in the Engine control unit 108 by the control unit 102,then at step 418, the control unit 102 will display the engine speed on theinstrument cluster 112 of the vehicle 200. 10 [00047] Once the engine speed is determined by the control unit 102 from the sensor 110 and the status of SDVC unit 108 is received by the control unit 102, at step 420, the control unit 102 access the Speed-volume mapping table stored in the SDVC unit 108. At step 422, if the engine speed is between X1 and X2, and if the volume level of the audio in the audio device 114 is 15 between Y1 and Y2, the control unit 103 maintains the same volume level as per the speed volume mapping table. At step 424, if the engine speed decrease from X1 i.e., from the predetermined speed range, at step 426, the control unit 102 gradually decrease the volume level of the audio to the corresponding volume range of the new predetermined engine speed range. At step 428, 20 when the engine speed increases from X2, i.e., from the predetermined speed range, at step 430, the control unit 102 gradually increases the volume level of the audio to the corresponding volume range of the new predetermined engine speed range. The updated volume level of the audio in the audio device 114 is displayed on the instrument cluster 112 of the vehicle 200. 25
