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 in automobiles.
BACKGROUND
State-of-the-art electronic horns such as an automotive horn are referred to as Dia 70 Disc Type Horn. The disc horn operation is based on the same principle as that of electric-bell. Accordingly, such horns include a housing assembly, a diaphragm assembly, a bobbin assembly, a resonator, etc. At least a conventional disc horn assembly for automobiles has been depicted in Figure 1.
As depicted in Figure 1, the housing assembly includes a sheet metal housing that encases a fixed iron core or fixed nucleus 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 terminal/connector through rivet and washer and the other end is 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 at least two metallic strip carrying contacts. One of the strips is a thin steel sheet also called spring, while the other is a comparatively thicker steel sheet also called support. The ends of the coil assembly 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, and the periphery of the diaphragm is rigidly held in the housing by crimping or closing. In operation, as supply from the DC source is switched ON, the current flows into the coil 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 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 coil assembly also returns to its original position, and thus contacts each other again. The circuit is again completed from 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 diaphragm with the moving iron core is set into a periodic motion.
The diaphragm assembly additionally comprises a round-sheet metal part called a resonator. During the movement of the moving iron core, the moving iron core 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 less lifecycle, non-durability, requiring 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 the equipment for vehicles. For example, the Original 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 state of art disc horns are based on the same principle as that of an electric bell and incorporate 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 facilitate the different requirements to optimize the space issues with a multi-purpose device.
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 contact breaker assembly, and last but not the least, a large number of mechanical parts. This is so since that conventional disc horn includes a "Contact Breaker assembly" which controls the switching of the horn.

In an example, the horn assembly 100 of Fig. 2 relates to an automotive horn. The horn 100 may be at least available in high pitch and low pitch variants. The horn 100 is multi-tone based and can be used for warning as well as alarming functions including Side stand warning alarm, Turn side lamp indication tone, Power on tone, and Keylock and unlock information tone.
Referring to Figure 2, the horn 100 includes at least one housing 11, at least one diaphragm 6, at least one fixed iron core 15, at least one coil assembly 9, and at least one controlling module 14. Housing 11 encases the fixed iron core 15 or alternatively referred to as a fixed nucleus 15 rigidly held to its bottom and aligned to its center axis. Housing 11 may be made of sheet metal, however, the housing may be made of any other material including plastic, without deviating from the scope of the present subject matter.

The switching of the power supply causes a change in magnetic fields generated in the coil assembly 9, and the change in the generated magnetic fields causes a change in the vibrating frequency of the diaphragm 6 to generate at least one of the plurality of tones.

In an embodiment, the at least one input signal and the output signal corresponds to at least one of the plurality of the tones.

The microcontroller 24 is adapted to generate 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 9, and 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.
In an embodiment, microcontroller 24 has the capability to detect the input signals up to 32K Hz.
An example of the power source 20 is a 12V DC battery. The regulated power supply supplied by the voltage regulator 25 is 5V.
In an embodiment, the input and output signals are 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

Figure 4 illustrates a pulse width modulation (PWM) applied for the operation of the horn 100 of Figure 2, in accordance with an embodiment of the present subject matter. More specifically, the controlling module 14 generates different kinds of the input PWM signal and output PWM signal as illustrated in Fig. 4. to generate different 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.

Figure 5 illustrates the front and back view of the controlling module 14 within the horn 100 of Fig. 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 of the electric power supply is generated and controlled by a controlling module assembly 21 having a controlling module 14 and a pin-connector 13 (also illustrated in Figure 7) with a pin mechanism and epoxy coating. More particularly, a 12V power supply is simultaneously supplied to a MOSFET 23 via coil assembly 9 and a voltage regulator 25. The 12V DC power supply is converted to a regulated 5V DC power from the voltage regulator 25 to provide the regulated power supply to the microcontroller 24. Then microcontroller 24 generates an output PWM signal that controls the switching of MOSFET 23. Such switching energizes/de-energizes bobbin assembly 9 at 12V.
In an embodiment, the pin-connector 13 acts as an interface for reconfiguring the microcontroller to enable the user-driven configuration of the horn assembly for the plurality of tones.
As supply from a DC power 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 14 by the virtue of the OFF state of the output PWM 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 14 controls the switching again due to the ON state of the output PWM signal, and the current supply is resumed ON. The current supply starts flowing again and magnetizes the fixed iron core 15. This process repeats again at around 450 cycles per second for high pitch horns/tones approximately and around 360 cycles per second for Low pitch horns/tones approximately. Accordingly, the diaphragm 6 with the moving iron core 7 is set into a periodic motion. Overall, the input and output PWM signals cause changes in the vibrating frequency of the diaphragm through the MOSFET (23) to generate at least one of the plurality of tones.
As the moving iron core 7 collides with the fixed iron core 15 during its movement to generate the tones, due to the movement of the diaphragm 6, the air between the diaphragm 6 and the resonator 2 is compressed and decompressed. Thus, resonator 2 amplifies the tones/sound generated by the collision of the moving iron core 7 with the fixed iron core 15.
Due to the unique coding, microcontroller 24 detects the input signal through the pin-connector 13 's pin (as later illustrated in Figs. 6 and 7). In an embodiment, the at least one input signal may be multiple or five different PWM (as illustrated in Figure 4) as per end-user requirements are generated. Similarly, in an embodiment, multiple PWMs or five different PWM leads to the generation of multiple or five different tones and continuous blowing of all multiple or five different tones/sound similar to a side stand warning alarm, a turn side lamp indication tone, a power-ON tone, and a key lock and unlock information tone. However, the horn 100 may also be construed to generate a single PWM for a single tone and thereby generate alarm function as per the user-defined configuration.
Further, the controlling module assembly 21 may further include a plurality of other components, e.g., 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 the microcontroller 24.
In an example, the reverse polarity protection diode is an avalanche diode or a Schottky diode.

More specifically, the circuit diagram represents the circuit diagram representation of the controlling module 14, the pin-connector 13, and the MOSFET 23, as identified in the preceding figures.

- Due to no contact breaker assembly, the residual accumulation due to wearing of mechanical contact breaker assembly, more heat generation due to arcing in contact breaker assembly, and last but not the least, a large number of mechanical parts is eliminated.
