Abstract
One of the main objects of the present invention is to provide a bone conduction microphone with simplified structure and easier manufacturing process. To achieve the above-mentioned objects, the present invention provides a bone conduction microphone, including: a housing; a circuit board opposite to the housing; and a vibration assembly locating between the housing and the circuit board. The vibration assembly includes a vibration membrane made of high temperature resistant dustproof breathable material, a weight fixed to the vibration membrane, and a first cavity formed between the vibration membrane and the circuit board. The bone conduction microphone further includes a pressure assembly locating between the vibration assembly and the circuit board for detecting a pressure change generated in the first cavity and converting the pressure change into an electrical signal.
