ECM chip

Product Description

MEMS Microphone is a product developed for the purpose of replacing the existing ECM.
And maintain the high prices compared to the ECM. However, it is a great advantage to maintain a stable characteristic. So spurring the MEMS development in RFsemi.

Features

  • Enhanced acoustic performance and stable structure using array diaphragm
  • High sensitivity using tiny & thin-film diaphragm
  • High SNR figure using high sensitivity and low noise features
  • Narrow range of sensitivity fluctuation
  • Suitable for mass-production by automatic assembly of SMD Module

Product Features

Applications

  • Smartphone
  • Laptop
  • Headset / Earphone
  • Digital Camera
  • AI speaker
