Knowles V2S200D Digital Voice Vibration Sensor

Knowles V2S200D Digital Voice Vibration Sensor is a high bandwidth, low-power specialized vibration sensor that improves voice call quality in noisy environments. This high-performance sensor is engineered to selectively pick up the speaker’s voice while suppressing other sounds, creating a comfortable and frustration-free voice call experience. The V2S200D provides a high 64.5dB(A) signal-to-noise ratio (SNR) in a compact package (3.30mm x 2.30mm x 0.93mm). The module features voice activity detection, imposter rejection, and 50dB acoustic isolation in noisy environments. Knowles V2S200D Digital Voice Vibration Sensor offers a solution to OEMs/ODMs wanting to enhance the user experience of their products while accommodating the significant constraints of industrial design and battery life. Upon integration into the system, the V2S200D emulates a digital mic with a pulse density modulation (PDM) interface for hassle-free hardware and software development.
