When the vibrator 2 is connected to the connecting portion 101, the second conductive pin 204 abuts against the first conductive pin 102 to cause the vibration assembly 200 to vibrate. Both the first conductive pin 102 and the second conductive pin 204 are two and correspond to each other one by one. Specifically, the first conductive pin 102 and the second conductive pin 204 are made of a metal material. Preferably, the first conductive pin 102 and the second conductive pin 204 are made of copper. Among them, when the vibrator 2 is connected to the connecting portion 101 of the wearing member 1, the first conductive pin 102 and the second conductive pin 204 come into contact and conduct electricity (energize), and the vibration assembly 200 vibrates to achieve bone conduction. This embodiment provides a bone conduction device to solve the problem that in the existing bone conduction headphones, the vibrator is fixedly connected to the wearing ring, and one vibrator can only be paired with one wearing ring, resulting in poor adaptability. The main solution is to configure the connection mode between the wearing member 1 and the vibrator 2 as a detachable and fixed connection. Since the wearing member 1 has a connecting portion 101 and a first conductive pin 102 exposed on the connecting portion 101, the vibrator 2 is detachably and fixedly connected to the connecting portion 101 of the wearing member 1 and has a second conductive pin 204 that abuts against the first conductive pin 102 to energize and cause the vibration assembly 200 to vibrate when the vibrator 2 is connected to the connecting portion 101. Therefore, the same vibrator 2 can be paired with multiple wearing members 1 of different size models (therefore, the relative position between the vibrator 2 and the skull can be changed by replacing the wearing members 1 of different size models to find the best bone conduction position), with good adaptability. At the same time, the wearing member 1 and the vibrator 2 are electrically connected and disconnected during the disassembly and assembly process, making the pairing convenient.

[0032] In the embodiment of the present invention, a first magnetic member 103 is provided on the connecting portion 101, and a second magnetic member 205 magnetically coupled with the first magnetic member 103 is provided inside the housing 201.

[0040] Among them, in addition to adopting the above structure, the vibration assembly 200 can also adopt the structure of a coil and a permanent magnet. According to Faraday's law, when the coil is energized, the magnetic force generated interacts with the original magnetic field of the permanent magnet to repel or attract each other, causing the permanent magnet to vibrate.

[0041] In the embodiment of the present utility model, an elastic member 213 is provided on one side of the second guide pin 204 of the housing 201. One end of the elastic member 213 abuts against the central position of the piezoelectric vibration element 203.
