Abstract
The present invention provides a bone conduction microphone including a housing and a circuit board connected with the housing. The circuit board has an acoustic channel. The microphone further includes a vibration assembly forming a first conduction cavity and a second conduction cavity. The vibration assembly includes a vibration member and a frame. The frame, the vibration member and the circuit board form a first conduction cavity. The frame, the vibration member and the circuit board form a second conduction cavity. The vibration of the vibration member is conducted to one side of the vibration diaphragm, and is also conducted to the other side of the vibration diaphragm. Compared with the related art, the bone conduction microphone of the present invention can effectively improve the sensitivity and the signal to noise ratio.
