Bone-Conduction MEMS Microphone

Bone-Conduction MEMS Microphone

Product Overview

The WBC252-01GD Bone-Conduction MEMS Microphone is a compact, high-performance microphone designed for next-generation wearable, industrial, and communication devices. With a 73 dB Signal-to-Noise Ratio (SNR) and ultra-low power consumption, it provides exceptional voice clarity even in loud or windy environments.

The microphone can emulate a PDM-interface digital microphone, allowing OEM/ODM developers to integrate it easily into their existing hardware and firmware architectures without additional complexity. Its miniature size also helps resolve industrial-design constraints and extend battery life in small consumer electronics.
