The bone conduction vibrator mechanism 300 is configured to receive the amplified electrical signals and convert the amplified electrical signals into vibration signals. The bone conduction vibrator mechanism 300 transmits the vibration signals to the mastoid process of the human body. The mastoid process transmits the vibration signals through the skull to the inner ear, where the vibration signals are ultimately converted into nerve stimulation in the cochlea and recognized by the human body.

[0038] The signal amplification mechanism 200 and the bone conduction vibrator mechanism 300 of this bone conduction device are designed and installed independently, which makes the structure and assembly process of the bone conduction device relatively simple, has good maintainability, and is very convenient for cleaning and maintenance of the headband 400. The signal amplification mechanism 200 and the bone conduction vibrator mechanism 300 are connected by the first connector 120 and are significantly farther apart than the integrated design, which effectively prevents vibration feedback howling.

[0039] In some examples, such as Figures 1 to 3 , Figure 8 and Figure 9 As shown, the signal amplification mechanism 200 includes: a housing 210, which has a sound receiving hole 213; a microphone 220, which is located inside the housing 210 and is correspondingly arranged with the sound receiving hole 213, and is configured to receive sound signals from the outside 210 through the sound receiving hole 213 and convert the sound signals into electrical signals; a power supply 230 and a control unit 240, which are both located inside the housing 210, and are electrically connected to the microphone 220 and the power supply 230, and are configured to receive electrical signals and amplify the electrical signals; and a waterproof and breathable membrane, which is located at the sound receiving hole 213 and is configured to prevent water from entering the interior of the housing 210 through the sound receiving hole 213.

[0040] In some embodiments, such as Figures 1 to 3 , Figure 8 andFigure 9 As shown, the signal amplification mechanism 200 further comprises a switch button 214, and the housing 210 is provided with a switch hole, and the switch button 214 is sealingly arranged in the switch hole.

[0041] In some examples, as shown in Figures 1 to 3 , Figures 5 to 7 As shown, the bone conduction vibrator mechanism 300 comprises a base, the base has an accommodating cavity with an open end, and the inner circumferential surface of the accommodating cavity is provided with an annular support surface 311 facing one side of the opening of the accommodating cavity; a support sheet assembly 380, the support sheet assembly 380 is arranged in the accommodating cavity and abuts on the support surface 311; a flexible sealing cover 330, the flexible sealing cover 330 is sealingly arranged at the opening of the accommodating cavity and abuts on the support sheet assembly 380; a vibration unit 340, the vibration unit 340 is located in the accommodating cavity and on the side of the support sheet assembly 380 away from the flexible sealing cover 330, and the vibration unit 340 is arranged to receive an amplified electrical signal and convert the amplified electrical signal into a vibration signal; a conductive sheet 350, the conductive sheet 350 is located on the side of the flexible sealing cover 330 away from the support sheet assembly 380, and the conductive sheet 350 is arranged to vibrate according to the vibration signal; and a second connecting piece 360, the second connecting piece 360 is arranged through the support sheet assembly 380 and the flexible sealing cover 330 and fixedly connects the vibration unit 340 and the conductive sheet 350, the vibration unit 340 and the conductive sheet 350 are hard connected through the second connecting piece 360, and the flexible sealing cover 330 supports the conductive sheet 350 and the support sheet assembly 380, so that the vibration loss of the vibration unit 340 to the conductive sheet 350 is small and the efficiency is high. When the vibration unit 340 vibrates, the conductive sheet 350 is driven to vibrate together through the second connecting piece 360, and the flexible sealing cover 330 deforms correspondingly under the vibration extrusion of the conductive sheet 350. The conductive sheet 350 contacts the scalp at the mastoid process of the human body, and the vibration signal is transmitted to the mastoid process of the human body, the mastoid process transmits the vibration signal to the inner ear through the skull, and finally the vibration signal is converted into nerve stimulation in the cochlea and recognized by the human body. It can be that the flexible sealing cover 330 is a silica gel sealing cover.

[0044] In some embodiments, a sealing waterproof structure is arranged between the conductive sheet 350 and the flexible sealing cover 330. It can be that the conductive sheet 350 and the flexible sealing cover 330 are sealed by means of glue (the sealing waterproof structure includes a glue connecting layer formed by the glue), so as to avoid water from entering the avoiding hole 370 on the flexible sealing cover 330 through the gap between the conductive sheet 350 and the flexible sealing cover 330, and then entering the inside of the bone conduction vibrator mechanism 300 from the avoiding hole 370 on the flexible sealing cover 330, thereby causing the electrical components (including the vibration unit 340) in the inside of the bone conduction vibrator mechanism 300 to be damaged by water.

[0045] In some embodiments, as shown in Figure 6 As shown, the support sheet assembly 380 comprises a support sheet 381 and a buffer sleeve 382 sleeved on the periphery of the support sheet 381, the buffer sleeve 382 abuts against the support surface 311 and is spaced apart from the flexible sealing cover 330, the middle part of the flexible sealing cover 330 is provided with a convex bump 331 protruding towards the support sheet 381, the convex bump 331 abuts against one side surface of the support sheet 381, and the vibration unit 340 abuts against the other side surface of the support sheet 381. In this scheme, the conductive sheet 350 and the vibration unit 340 do not move relatively when the conductive sheet 350 and the vibration unit 340 vibrate in the axial direction of the avoiding hole 370. The avoiding hole 370 on the flexible sealing cover 330 is located on the convex bump 331.

It can be that the vibration unit 340 is electrically connected with the third connecting terminal 321 through a lead wire, and the control unit 240 is electrically connected with the first connecting terminal 211 through a lead wire.

The third magnetic attachment 322 can include two third magnets, the fourth magnetic attachment 132 can include two fourth magnets, and the two third magnets attracted to the two fourth magnets can have opposite magnetic properties at one end, thereby preventing mistakes and avoiding misalignment of the two third connection terminals 321 and the two fourth connection terminals 131 due to incorrect positioning of the bone conduction vibrator mechanism 300 on the second mounting seat 130.

[0049] In some embodiments, as shown in Figure 9 The signal amplification mechanism 200 is also provided with a first magnetic shielding member 250, which is located on the side of the first magnetic attachment 212 away from the second magnetic attachment 112.
