FIELD OF THE INVENTION
The present subject matter relates to an acoustic device and in particular to a compact-sized reconfigurable electronic horn for generating a plurality of tones as well as a buzzer of a plurality of patterns, for vehicles.
BACKGROUND
Conventional horns for vehicles are referred to as Dia 70 disc type electromechanical horns. The disc horn operation is based on the same principle as that of an electric bell. Accordingly, such horns include a housing assembly, diaphragm, bobbin assembly, resonator, etc. At least, a conventional disc horn assembly for a vehicle has been depicted in Figure 1.
As depicted in Figure 1, the housing assembly is a sheet metal housing which encases a fixed iron core rigidly held to its bottom and aligned to its center axis. Around the fixed iron core, a coil assembly is mounted. One end of the coil assembly is connected with a first terminal/connector through one or more rivets and washers whereas the other end of the coil assembly are connected with a second terminal/connector through a contact breaker (CB) assembly that is held offset from the center axis of the housing. The CB assembly mainly includes two metallic strip-carrying contacts. One of the strips is made of a thin steel sheet also called a spring, the other is a comparatively thicker steel sheet also called support. The ends are insulated from each other by an insulating tab except at the contacts on their ends. Normally, in idle conditions and also to an extent during the operation, these contacts of the CB assembly contact each other.
The diaphragm assembly includes a moving iron core fixed to a sheet metal diaphragm, the periphery of which is rigidly held in the housing by crimping or closing. In operation, as the supply from a DC source is switched ON, the current flows into the coil assembly resulting in an electromagnetic field in the fixed iron core. This causes the moving iron core to be pulled towards the fixed iron core. During its forward motion towards the fixed iron core, the moving iron core pushes the spring and in turn moves the contacts away

from each other thus breaking the electric circuit. This stops the current further and causes the magnetic flux to decrease.
Due to the elasticity of the material of the diaphragm, the diaphragm pulls back the moving iron core back to its equilibrium position. As the moving iron core moves back, the spring assembly also returns to its original position, and thus contacts each other again. The electric circuit is again completed from a broken state and current flow resumes within the circuit. The aforesaid make and break circuit-based operation repeats again, for example at around 450 cycles per second for high pitch horn, 400 cycles per second for Medium pitch, and around 360 cycles per second for Low pitch horns. This way, the diaphragm with the moving iron core is set into a periodic motion.
The diaphragm assembly additionally includes a round-sheet metal part called a resonator. During the movement of the moving iron core, it hits the fixed iron core, resulting in a vibration transferred to the resonator. The resonator comes in resonance and amplifies the sound through air columns existing between the resonator and the diaphragm.
However, the conventional horn assemblies are confronted with demerits such as low lifecycle, non-durability, requires periodic adjustments, and maybe exclusively used for horn function or in other words for loud sounds. The same at least posed challenges to the manufacturers of equipment for vehicles. For example, the Orignal Equipment Manufacturers (OEMs) are likely to have space issues in their vehicle as a separate acoustic device such as a beeper for providing alarm function (i.e., turn indicator and side stand warning) is required to be connected and placed separately in the vehicle. The conventional disc horn is based on the same principle as that of an electric bell and incorporates the only feature of acting as a "Warning device" with a defined life cycle of 100,000. Accordingly, there lies at least a need for an integrated solution to multiple requirements to optimize the space issues with a multi-purpose device. Also, the components internally mounted must have the ability to sustain temperatures up to 140°C.
Furthermore, the conventional horn assemblies are confronted with demerits such as residual accumulation due to wearing of mechanical contact breaker assembly, more heat generation due to arcing in the contact breaker assembly, and last but not the least, a large number of mechanical parts.

The present invention relates to a compact-sized reasonable electronic horn for a vehicle, for generating a plurality of tone, such as a Dia 70mm Disc E-horn. The electronic horn of the present subject matter is configured to be implemented with a single side two layers controlling module, as described in a later part of the present disclosure.
An example of the horn of the present subject matter may be a Dia 70mm Disc E-horn with an internal controlling module that is configured to generate the plurality of tones as well as buzzer of a plurality of patterns with respect to the input signals from a vehicle control module, without the need of make and break contacts.
In an embodiment, the controlling module is based on a Printed Circuit Board (PCB). Similarly, in an embodiment, the generated signal is a Pulse Width Modulation (PWM) signal. The different signals' frequencies with different bands cause changes in the vibrating frequency of a diaphragm through a power MOSFET and thereby leads to the generation of the plurality of tones.
Such generation of the plurality of tones from a single horn at least adduces a unique feature that provides the horn as a compact-sized multi-application device (i.e., honking, beeping, etc.).

The controlling module includes a feature of calibration through Graphical User Interface. Further, the controlling module is disposed within the housing and is adapted for a dia. 70mm Horn. Further, the components of the horn of the present subject matter are made of one or more material that withstands a temperature up to 140°C.
The electronic horn is configurable by the presence of a specific microcontroller coding facility in the controlling module underlying the horn assembly. At least due to such unique coding and the microcontroller being configurable, a plurality of tone is rendered. Coding with the microcontroller is done in a way that the horn's Electronic Control Unit (ECU) can communicate with the vehicle's ECU through hardware inputs and can detect a plurality of inputs. As apart of a Graphical User Interface to achieve such configuration of the microcontroller, a unique pin-connector is provided as an interface together with a software-enabled application to control the Graphic User Interface during programming. This at least enables the user-driven configuration of the electronic horn as a part of customization to generate better tones by coding. The configuration may be done externally without dismantling the horn assembly.
As a part of obtaining a multi-application device, the horn may be configured/programmed to be used for side-stand warning alarm, turn side lamp indication tone, Power ON tone & key-lock, and unlock information tone. Besides this, the horn does not require any other type of adjustment during its life cycle.
As a part of obtaining a high thermal durability product, the parts internally mounted can sustain temperature up to 140°C. Besides this, the components of the horn can sustain a sinusoidal vibrational load of up to lOg.
Embodiments of the present invention will be described below in detail with reference to the accompanying drawings.

In an example, the hom 100 of Figure 2, includes an internal controlling module 10. More particularly, the present subject matter relates to "Disc E-horn with a plurality of alarming functions with an internal controlling module" in Dia. 70mm for vehicles. The hom 100 may be at least available in high tone, medium tone, and low tone variants. The hom 100 is configured to be used for warning as well as alarming functions including a side stand warning alarm, turn side lamp indication tone, power on tone, a keylock, and unlock information tone.
Figure 3 illustrates a block diagram of an electrical connection of a controlling module of a hom 100 of Fig. 2, in accordance with an embodiment of the present subject matter. As depicted in Figure 3, the controlling module 10 includes a voltage regulator 25, a microcontroller 24, and a MOSFET 23. The voltage regulator 25 is connected to the power source 20 and adapted to convert the unregulated power supply of the power source 20 to a

regulated power supply. In an embodiment, the power source may include but is not limited to a battery and the power of the battery is 12V DC. Microcontroller 24 is connected to the voltage regulator 25 at one end, for receiving the regulated power supply, and the vehicle control module 28 at another end, for receiving the input signal from the vehicle control module 28. The MOSFET 23 is connected to the coil assembly 12 at one end and the microcontroller 24 at another end, and adapted to simultaneously receive the unregulated power supply from the power source 20 via the coil assembly 12 and the regulated power supply from the voltage regulator 25. In an embodiment, the unregulated power supply is 5V DC, however, a different unregulated power supply may be used without deviating from the scope of the present subject matter.
The microcontroller 24 is adapted to generate the at least one output signal based on the at least one input signal, for controlling the switching of MOSFET (23) which in turn controls the switching of the power supply to the coil assembly 12. The at least one output signal causes a change in the vibrating frequency of the diaphragm through the MOSFET 23 to generate the at least one of the plurality of tones and/or the buzzer of the plurality of patterns.
Referring to figure 2, the horn 100 includes a sheet metal housing 13 which encases a fixed iron core 15 or alternatively referred to as fixed nucleus 15 rigidly coupled to its bottom and aligned to its center axis. Around the fixed iron core 15, a coil assembly 12 or a bobbin assembly 12 having a spool and coil, is mounted and receives electricity via a connector assembly having a connector 14, and Allen Bolt 8 to produce a magnetic field. The magnetic field thus produced attracts the moving iron core 7 fixed to the diaphragm 6 in such a manner that the electrical supply being supplied to the bobbin assembly 12 is controlled by the controlling module 10 and thereby the electric current flow and generate the magnetic field. The magnetic field ceases and resumes in accordance with the controlling module 10's generated signals. In an embodiment, the generated signal is Pulse Width Modulation (PWM) signals.
It will be understood by those skilled in the art that various changes in form and detail may be made therein without departing from the scope of the invention. For example, the present invention or at least one technical feature of the present invention may be

implemented using any combination of computer programming software, firmware, or hardware.
In an embodiment, the controlling module 10 is designed on a printed circuit board, however, in another embodiment, the controlling module 11 may be designed in a different way, without deviating from the scope of the present subject matter.
The memory may include any non-transitory computer-readable medium known in the art including, for example, volatile memory, such as static random access memory (SRAM) and dynamic random access memory (DRAM), and/or non-volatile memory, such as read-only memory (ROM), erasable programmable (ROM), flash memories, hard disks, optical disks, and magnetic tapes.
The modules, amongst other things, include routines, programs, objects, components, data structures, etc., which perform particular tasks or implement data types. The modules may also be implemented as, signal processors, state machines, logic circuitries, and/or any other device or component that manipulate signals based on operational instructions.
Further, the modules can be implemented in hardware, instructions executed by a processing unit, or by a combination thereof. The processing unit can comprise a computer, a processor, a state machine, a logic array, or any other suitable devices capable of processing instructions. The processing unit can be a general-purpose processor which executes instructions to cause the general-purpose processor to perform the required tasks or, the processing unit can be dedicated to performing the required functions. In another embodiment of the present disclosure, the modules may be machine-readable instructions software that, when executed by a processor/processing unit, perform any of the described functionalities.
Figure 4 illustrates an input and output signal applied for the operation of horn 100 of Figure 2, in accordance with an embodiment of the present subject matter. More specifically, the controlling module 10 generates different kinds of inputs and output signals as represented by Fig. 4. to generate a plurality of tones or frequencies corresponding to Side

stand warning alarm, Turn side lamp indication tone, Power on tone, keylock, and unlock information tone with a life cycle of 1,000,000.
Further, Microcontroller 24 has the capability to detect input signals up to 32K Hz. Table 2 shows the various input signals to generate the plurality of tones.

Figure 5 illustrates a front and back view of the controlling module 10 within a horn 100 of Figure 2, in accordance with an embodiment of the present subject matter. In operation and in continuation to the description of preceding Fig. 3, the switching is generated and controlled by a controlling module assembly 21 having a controlling module 10 and a pin-connector 14 with pin mechanism and epoxy coating.
More particularly, the 12V power supply is simultaneously supplied to the MOSFET 23 via the coil assembly 9 and the voltage regulator 25. The 12V DC power supply is converted to a regulated 5V DC power supply by the voltage regulator 25 to provide the regulated power to the microcontroller 24. Microcontroller 24 generates an output signal (i.e., output Pulse Width Modulation signal) that controls the switching of the MOSFET 23. Such switching energizes/de-energizes the bobbin assembly 12 at 12V.
As supply from the DC source or battery is switched ON, the current flows through a copper coil of the coil assembly 9 which magnetizes the fixed iron core 15. This causes the moving iron core 7 fixed on the diaphragm 6 to be pulled towards the fixed iron core 15. As the current supply becomes OFF through controlled switching of the controlling module 10 by virtue of the OFF state of the output signal waveform, the fixed iron core 15 is

demagnetized. Due to the elasticity of the material of the diaphragm 6, the diaphragm 6 pulls back the moving iron core 7 back to its equilibrium position. As the moving iron core 7 moves back, the controlling module 10 controls the switching again, due to the ON state of the output signal waveform, and the current supply is resumed ON. The current flow starts flowing again and magnetizes the fixed iron core 15. This process repeats again at around 450 cycles per second for high pitch/tone horns approximately and around 360 cycles per second for low pitch/tone horns approximately. Accordingly, the diaphragm 6 with the moving iron core 7 is set into a periodic motion. Overall, the different output signals waveform cause changes in the vibrating frequency of the diaphragm through the MOSFET 23 and thereby leads to the production of the plurality of tones.
Further and as a part of the production of acoustics, the moving iron core 7 collides with the fixed iron core 15 during its movement. Due to the movement of the diaphragm 6, the air between the diaphragm and the resonator 2 is compressed and decompressed. The resonator 2 amplifies the sound/tone generated by the collision of the moving iron core 7 with the fixed iron core 15.
Due to unique coding in microcontroller 24, microcontroller 24 detects input signal through the pin-connector 14's pin (as later illustrated in Figures 6 and 7). The input signal may be multiple or five different Pulse Width Modulation signals (as shown in figure 4) as per end-user requirement. The multiple or five different PWM signals lead to a generation of multi or five different tones and continuous blowing of all multi or five different tones/sound similar to a side stand warning alarm, Turn side lamp indication tone, Power on tone, keylock, and unlock information tone.
However, the horn 100 may also be configured to generate a single input signal (i.e., PWM signal) for a single tone and thereby generate an alarm function as per the application of the end-user.
Further, the controlling module assembly 21 includes miscellaneous other components such as a Transient-voltage-suppression (TVS) diode for surge voltage protection due to the coil assembly 9, a reverse polarity protection diode, and a Voltage sensing circuit for over and under-voltage protection through a microcontroller 24. An

example of the reverse polarity protection diode includes, but not limited to, Avalanche diode/ Schottky diode.

More specifically, the circuit diagram represents the circuit diagram representation of components as identified in the preceding figures.

to an aspect, the horn 100 generates a warning sound along with a basic alarm function. In an example, the requirements that were met are a Side stand warning alarm, Turn side lamp indication tone, Power on tone, Keylock, and unlock information tone with a life cycle of 1,000,000.
Figure 8 illustrates a method 800 for generating a plurality of tone as well as buzzer of a plurality of patterns for a vehicle, in accordance with an embodiment of the present subject matter. The plurality of tones, as well as a buzzer of a plurality of patterns, is generated from a compact-sized reconfigurable horn 100 having a housing 13, at least one diaphragm 6, at least one fixed iron core 15, and at least one coil assembly 12. At block 802, the method includes converting, by a voltage regulator 25, an unregulated power supply from a power source 20 to a regulated power supply.

At block 806, the method further includes receiving, by the microcontroller 24, at least one input signal from a vehicle control module 28. At block 810, the method further includes simultaneously receiving, by a MOSFET 23, the unregulated power supply from the power source 20 via the coil assembly 12 and the regulated power supply from the voltage regulator 25. At block 812, the method further includes generating, by the microcontroller 24, at least one output signal based on at least one input signal. At block 814, the method further includes controlling, by the microcontroller 24, the switching of the power supply to the coil assembly 12 through the switching of MOSFET 23. At block 816, the method further includes changing the vibrating frequency of the diaphragm 6 through the switching of the MOSFET 23 to generate at least one of the plurality of tones as well as the buzzer of a plurality of patterns.

• The present invention facilitates calibration through Graphical User Interface.
• The screwing Process is used.
• A complete circular controlling module (i.e., PCB as illustrated in Fig. 5).
