MEMS MICROPHONE

A MEMS microphone includes a substrate, a base, a capacitance system, and at least one cantilever structure. The substrate includes a back cavity, the base is disposed on one side of the substrate, and the capacitance system is disposed on the base. The capacitance system includes at least one back plate assembly, at least one first vibration diaphragm, and at least one second vibration diaphragm. The at least one first vibration diaphragm includes a first sub-vibration diaphragm, and the at least one second vibration diaphragm includes a second sub-vibration diaphragm. The sub-vibration diaphragm and the second sub-vibration diaphragm form a cantilever beam structure on the base, which increase compliance of the at least one first vibration diaphragm and the at least one second vibration diaphragm and reduce tension of the at least one first vibration diaphragm and the at least one second vibration diaphragm, thereby improving sensitivity of the microphones.
