PUI Audio VMM-1627L-R Bone Conduction MEMS Microphone is designed to enhance the hearing experience under challenging environments over standard microphones. This Micro-Electromechanical System (MEMS) microphone works by sensing the vibration signals precisely and reliably transmitted through bone and hence do not pick up the surrounding noise. The VMM-1627L-R bone conduction MEMS microphone features a compact size, -29±2dBV/g sensitivity, 73dB (A) S/N ratio, 5kHz peak frequency, and 300kΩ impedance. The compact size of the microphone allows it to fit easily and provide design flexibility in various types of applications. This microphone is ideal for wearables, smart voice systems, medical/health monitoring, industrial, automotive, and military applications.
