Analog MEMS Microphone Unit Which Supports High Sound Pressure Input Has Been Developed

Hosiden has developed an analog MEMS microphone unit which has accomplished low distortion even when high sound pressure is applied.
Thinking out the differences in the inner structures and acoustic characteristics of devices, we have lined up two variations: top sound hole type and reverse sound hole type. A wide variety of demands are expected for this product as a microphone unit used in smart phones, portable game machines, digital cameras, automotive devices; etc.

Typical Application
  • Mobile phones, smart phones, PCs, game machines, digital cameras/ video cameras, in-car equipments; etc.
