Bone conduction microphone

A bone conduction microphone, comprising:

• a laminated structure formed by a vibration unit and an acoustic transducer unit;
• a base structure configured to carry the laminated structure, at least one side of the laminated structure being physically connected to the base structure, wherein
• the base structure vibrates based on an external vibration signal,
• the vibration unit is deformed in response to the vibration of the base structure, and
• the acoustic transducer unit generates an electrical signal based on the deformation of the vibration unit, wherein:
• the vibration unit includes a suspended film structure, the acoustic transducer unit includes a first electrode layer, a piezoelectric layer, and a second electrode layer that are arranged in sequence from top to bottom, the suspended film structure is connected with the base structure through a peripheral side of the suspended film structure, and the acoustic transducer unit is arranged on an upper surface or a lower surface of the suspended film structure.
