MEMS Microphone

3S has successfully pioneered in the development of MEMS microphone by applying different advanced techniques such as CMOS processed microphone diaphragm with outstanding acoustic characteristics that is sustainable to both high temperature and humidity. These unique features allowed 3S MEMS microphones easily adopted with fully automated SMT line, including reflow process. 

3S offers its MEMS microphone in both Digital and Analog versions to facilitate different application usages found on the market today. Being as one of the world's tiniest MEMS microphone derived from an unique single-chip design, it offers system designers with more creative flexibilities as well as enormous space-saving advantages. The MEMS microphone from 3S already passed various rigorous acoustic tests as credentials for product quality and reliability assurance.
