[0043] Bone conduction hearing aids include electronic components such as bone resonators, main control boards, and power supplies. In related technologies, when the main control board is electrically connected to components such as power supplies and bone resonators, soldering is usually used. This method of connection is complex, inconvenient for later maintenance and replacement of individual parts, and the soldering method is prone to cold solder joints, affecting the reliability of the connection between various parts.

[0044] To solve the above technical problems, refer to Figures 1 to 4As shown, this invention proposes a bone conduction hearing aid 100, which includes a housing 10. Inside the housing 10 are a main control board 20, a microphone 30, a bone resonator 40, and a battery 80. The microphone 30 collects sound and converts the sound signal into an electrical signal. The bone resonator 40 includes a first bone resonator 41 and a second bone resonator 43, and is used to convert the electrical signal into a vibration signal. The battery 80 supplies power to the main control board 20, the microphone 30, and the bone resonator 40.

[0045] The first bone resonator 41 is electrically connected to the main control board 20 via a plug-in connection, the second bone resonator 43 is electrically connected to the main control board 20 via a plug-in connection, the microphone 30 is electrically connected to the main control board 20 via a plug-in connection, and the battery 80 is electrically connected to the main control board 20 via a plug-in connection.

[0046] Understandably, the housing 10 has an internal installation space where the main control board 20, microphone 30, bone conduction device 40, and electrical components are installed and fixed. The main control board 20 can integrate multiple modules, such as a volume control module, a microphone module, and a processing module. The main board can perform functions such as adjusting and controlling the volume, collecting and processing sound signals, and converting sound signals into vibration signals. The microphone 30 is used to collect sound and convert sound signals into electrical signals. The microphone 30 can be covered with vibration-damping silicone to prevent noise from the microphone 30 vibrating. The bone conduction device 40 includes a first bone conduction device 41 and a second bone conduction device 43, which can be installed at the ears respectively. The bone conduction device 40 can convert sound signals into vibration signals. By converting sound signals into mechanical vibrations of different frequencies, sound waves are transmitted through the skull. The sound waves are transmitted directly to the auditory nerve through the bone, which can help people with hearing impairments hear again. Battery 80 can be a lithium battery 80, which has a charging function and can be equipped with a charging port, which helps to extend its service life. Battery 80 can power components such as main control board 20, microphone 30 and bone vibrator 40.

[0047] Reference Figure 2 As shown, the main control board 20 can be equipped with multiple sockets and plugs, the first bone resonator 41 and the second bone resonator 43 can also be equipped with multiple plugs and sockets, the microphone 30 can be equipped with at least one plug and socket, and the battery 80 can be equipped with at least one plug. The first bone resonator 41 can be connected to the main control board 20 by plugging in, the second bone resonator 43 can be connected to the main control board 20 by plugging in, the microphone 30 can be electrically connected to the main control board 20 by plugging in, and the battery 80 can be electrically connected to the main control board 20 by plugging in. The plug-in connection method facilitates the installation and assembly of various components and also facilitates future maintenance and replacement of components.

[0048] In one embodiment of this application, reference is made to Figure 2 and Figure 3 As shown, the bone conduction hearing aid 100 also includes a first adapter plate 51 and a second adapter plate 53. The first adapter plate 51 is electrically connected to the main control board 20, and the first bone resonator 41 is plugged into the first adapter plate 51 to be electrically connected to the first adapter plate 51 by plugging. The second adapter plate 53 is electrically connected to the main control board 20, and the second bone resonator 43 is plugged into the second adapter plate 53 to be electrically connected to the second adapter plate 53 by plugging.

[0049] Understandably, to facilitate a more rational layout between components, an adapter board can be used to achieve electrical connections between them. The adapter board can be equipped with multiple sockets and plugs; two adapter boards can be installed, one for each of the two earpieces. A socket can be installed on the first bone vibrator 41, which can be plugged into the plug of the first adapter board 51 for electrical connection. The connection method between the second bone vibrator 43 and the second adapter board 53 is the same as that between the first bone vibrator 41 and the first adapter board 51, and will not be repeated here. It should be noted that both the first adapter board 51 and the second adapter board 53 can be PCB boards, and the PCB boards can be electroplated with circuitry, thereby enabling electrical connections between the sockets and plugs. By using the adapter board to electrically connect the components, wiring can be saved, the wiring layout is simpler, and installation is easier.

[0050] In one embodiment of this application, reference is made to Figure 2 As shown, the first adapter board 51 is also connected to a microphone 60, which is electrically connected to the first adapter board 51 via a plug-in connection. Understandably, the hearing aid of this application can also have a voice call function. The first adapter board 51 is provided with a microphone 60 socket, and the microphone 60 is plugged into this socket to achieve an electrical connection. The main control board 20 can be equipped with a Bluetooth module, which can connect to a mobile phone via Bluetooth to achieve the voice call function in conjunction with the microphone 60.

[0051] In one embodiment of this application, reference is made to Figures 1 to 3 As shown, the outer casing 10 includes a first casing 11, a second casing 13, and a rear hanger 15. The main control board 20, the first bone vibrator 41, and the first adapter plate 51 are disposed inside the first casing 11; the second bone vibrator 43 and the second adapter plate 53 are disposed inside the second casing 13; one end of the rear hanger 15 is connected to the first casing 11, and the other end of the rear hanger 15 is connected to the second casing 13.

[0052] Understandably, the first housing 11 is located on the right ear side, the second housing 13 is located on the left ear side, and the back hook 15 hangs behind the neck. The first housing 11 and the second housing 13 are respectively snapped onto both ends of the back hook 15. The first housing 11 and the second housing 13 are similar in shape and size, and are symmetrically arranged. Both the first housing 11 and the second housing 13 have installation space inside. The first bone vibrator 41, the main control board 20, and the first adapter plate 51 are located inside the first housing 11. Multiple screw seats can be provided inside the first housing 11. Through holes can be provided on the main control board 20 and the first adapter plate 51. The main control board 20 and the first adapter plate 51 can be fixedly connected to the first housing 11 by screws. The second bone vibrator 43 and the second adapter plate 53 are installed inside the second housing 13. The connection method of the second bone vibrator 43 and the second adapter plate 53 is the same as the connection method in the first housing 11, and will not be described again here.

[0053] In one embodiment of this application, reference is made to Figures 2 to 4 As shown, the bone conduction hearing aid 100 also includes a first signal line 71 and a second signal line 73. One end of the first signal line 71 is plugged into the main control board 20, and the other end of the first signal line 71 is plugged into the first adapter board 51, so that the first adapter board 51 is electrically connected to the main control board 20. One end of the second signal line 73 is plugged into the main control board 20, and the other end of the second signal line 73 is plugged into the second adapter board 53, so that the second adapter board 53 is electrically connected to the main control board 20.

[0054] Understandably, both the first signal line 71 and the second signal line 73 can be a bundle of multiple cables forming a single transmission line. Both have plugs at both ends. One end of the first signal line 71 is plugged into the first adapter board 51, and the other end is plugged into the main control board 20, electrically connecting the main control board 20 and the first adapter board 51. This allows the sound signal to be converted into a vibration signal and transmitted to the first bone resonator 41, and also transmits the signal collected by the microphone 60 to the main control board 20. One end of the second signal line 73 is plugged into the main control board 20, and the other end is plugged into the second adapter board 53, electrically connecting the second adapter board 53 and the main control board 20. This allows the sound signal to be converted into a vibration signal and transmitted to the second bone resonator 43.

[0055] In one embodiment of this application, the second signal line 73 is threaded through the rear hanger 15. It is understood that the rear hanger 15 is hollow, allowing the second signal line 73 to be threaded through it, thus protecting the circuit.

[0056] In one embodiment of this application, reference is made to Figure 3 and Figure 4As shown, the microphone 30 is disposed inside the second housing 13. The end of the second signal line 73 away from the main control board 20 has two connectors. One connector is plugged into the microphone 30 to make the microphone 30 electrically connected to the main control board 20. The other connector is plugged into the second adapter board 53 to make the second adapter board 53 electrically connected to the main control board 20.

[0057] Understandably, the microphone 30 can be housed within the second housing 13. A socket can be installed on the microphone 30, and one end of the second signal line 73 can be plugged into the microphone 30 to establish an electrical connection between the microphone 30 and the main control board 20. This allows the sound information collected by the microphone 30 to be transmitted to the main control board 20, processed by the processing module, converted into a vibration signal, and then transmitted to the bone resonator 40. The end of the second signal line 73 furthest from the main control board 20 can have two connectors: one connector plugged into the microphone 30, and the other connector plugged into the second adapter board 53. The end of the second signal line 73 used for connection to the main control board 20 can be integrated into a single plug or have two separate plugs.

[0058] It should be explained that the microphone 30 can also be plugged into the second adapter board 53 to achieve an electrical connection between the microphone 30 and the second adapter board 53. Since the second adapter board 53 and the main control board 20 are plugged into each other, an electrical connection between the microphone 30 and the main control board 20 can be achieved. However, this connection method involves more wiring, which will cause signal attenuation and affect the transmission quality. On the other hand, the battery 80 is located inside the second housing 13, and the microphone 30 is installed on the side of the battery 80 away from the second bone resonator 43. When the microphone 30 is plugged into the second adapter board 53, a signal line will pass through the battery 80. The current signal generated by the battery 80 will interfere with the sound signal of the microphone 30 and affect the performance of the hearing aid.

[0059] In one embodiment of this application, reference is made to Figure 3 As shown, the battery 80 is disposed inside the second housing 13; the bone conduction hearing aid 100 also includes a third signal line 75, one end of which is connected to the battery 80 and the other end is inserted into the second adapter plate 53 so that the battery 80 is electrically connected to the second adapter plate 53.

[0060] Understandably, one end of the third signal line 75 can be soldered to the battery 80, and the other end can be equipped with a plug that can be plugged into the socket of the second adapter board 53 to realize the electrical connection between the battery 80 and the second adapter board 53. The current supplied by the battery 80 can be transmitted to the main control board 20 through the second adapter board 53 and the second signal line 73, and then transmitted to the first adapter board 51 through the first signal line 71 to realize the power supply to the main control board 20, the first bone resonator 41, the second bone resonator 43, the microphone 30 and other components.

[0061] In one embodiment of this application, one end of the third signal line 75 connected to the battery 80 is soldered to the battery 80. The end of the third signal line 75 connected to the battery 80 can be soldered to the battery 80. When the battery 80 is damaged, both the battery 80 and the third signal line 75 are replaced simultaneously.

[0062] In one embodiment of this application, reference is made to Figure 2 As shown, a charging interface 21 is provided on the main control board 20;

[0063] And / or, the main control board 20 is equipped with volume control buttons 23;

[0064] And / or, a power button (not shown) is provided on the main control board 20;

[0065] And / or, the main control board 20 is also equipped with LED indicator lights (not shown).

[0066] Understandably, a charging interface 21 can be provided on the main control board 20 for charging the battery 80.

[0067] Optionally, a volume control button 23 can be set on the main control board 20, which can adjust the volume by adjusting the vibration frequency and amplitude of the bone vibrator 40.

[0068] Optionally, the main control board 20 is provided with a power button (not shown) for turning the bone conduction hearing aid 100 on or off.

[0069] Optionally, the main control board 20 is also equipped with an LED indicator (not shown), which can be used to determine the battery level, Bluetooth connection status, etc., based on the color or flashing frequency of the LED indicator (not shown).

[0070] The above description is merely a preferred embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural transformations made using the contents of the present invention's specification and drawings under the inventive concept of the present invention, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present invention.
