Abstract
A MEMS microphone includes a substrate having a back cavity, a vibration diaphragm system, and a housing. The vibration diaphragm system includes at least two sub-vibration diaphragm assemblies, a slit is formed between adjacent two of the at least two sub-vibration diaphragm assemblies, one end, distal from the housing, of each of the at least two sub-vibration diaphragm assemblies is fixed to a cross beam assembly, and first gaps are formed between the at least two sub-vibration diaphragm assemblies and inner sides of the housing, so that the at least two sub-vibration diaphragm assemblies form a cantilever beam structure, which increases compliance of the vibration diaphragm system and further improves sensitivity of microphones.
