Description

Technical Field

[0001] The present invention relates to the field of bone conduction, in particular to a bone conduction speaker and a testing method thereof. Background Art

[0002] Bone conduction speakers can convert electrical signals into mechanical vibration signals, and transmit the vibration signals to the cochlea through human tissue and bones, allowing the user to hear the sound. Compared with air conduction speakers that produce sound through the diaphragm driving the air to vibrate, bone conduction speakers usually use testing equipment to test the vibration components of the speaker during the production process to ensure the quality of the speaker.

[0003] At present, when the test device used in the production of bone conduction speakers is working, the vibration component of the speaker is fixed on the test device through a clamping structure for testing. During the test process, the vibration component needs to be replaced frequently, and then the new vibration component is fixed on the test device. Since this process is manually operated, the clamping structure needs to be repeatedly operated during replacement, which is a relatively cumbersome process. In addition, the test device stops working during the replacement process and continues testing after the replacement, which has low work efficiency. Summary of the invention

[0013] Beneficial effects of the present invention: (1) When the present invention is in use, the vibration component to be tested is pressed against the vibration sensor through the squeezing mechanism, and then the test work is carried out.
