Product name : Silicon microphone 3722 Size 3.76 (mm) * 2.24 (mm) * 1.1 (mm) Directivity: omnidirectional
Meet ROHS standards
MEMS microphone is a compact microphone package in which MEMS chip, an acoustic sensor (acoustic transducer), an IC chip for signal processing are assembled. The MEMS chip is formed into a chip by forming a microstructure on a silicon wafer using the techniques of photolithography, etching, etc., applying semiconductor manufacturing technology. It is only several millimeters in size, and about three pieces of MEMS microphones are mounted in one smartphone. MEMS microphones are also used for a microphone with earphones for hands-free calls, headphones with noise canceling functions, and so on.
