MEMS MIC

Silicon microphones have the advantages of small size, concentrated sensitivity, high signal-to-noise ratio, low power consumption, low distortion, stable performance, high reliability, omnidirectional, etc. They have complete specifications and are divided into two categories: digital microphones and analog microphones. They are widely used in mobile phones, cameras, Bluetooth headsets, on-board Bluetooth and other electronic devices.


>Analog microphone has super mini size package products (SA2718 series)

>Analog microphone has superior RF interference suppression function and high SNR performance

>Piezoelectric microphone has good IPX8 waterproof performance

>Piezoelectric microphone has superior RF interference suppression function and high SNR performance

>Digital microphone with ultra-low standby power consumption

>Digital microphone with high sensitivity and high signal-to-noise ratio
