Single-chip MEMS Microphone

3S is the first company in Taiwan to successfully design and mass produce MEMS microphones chips. The single-chip MEMS microphone adapts a dedicated CMOS process to fabricate a microphone diaphragm and a pre-amplifier circuits in a single die. The product features excellent uniformity and coherency in acoustics characteristics such as sensitivity and phase distributions, and it also features a smallest microphone package size in the world. It is mainly used in active noise canceling headphones, Bluetooth headsets, and notebooks.

3S offers both analog output type and digital output type single chip MEMS microphones which can be easily adapted by smart phones, smart speakers, notebooks, Bluetooth headsets, TVs,… etc.suitable for all kinds of electronic products such as smart phones, smart speakers, notebooks, Bluetooth headsets, TVs,… etc. All types of MEMS microphones have passed various acoustic characteristics and reliability tests. The products have excellent acoustic characteristics and reliable quality. 3S is one of the few companies in the world that offers a full range of MEMS microphones.
