High-Performance Digital Voice Vibration Sensor

V2S200D: A First-of-its-Kind Digital Voice Vibration Sensor

A high bandwidth, low-power specialized vibration sensor to improve voice call quality in noisy environments

More than ever, consumers use audio devices, such as True Wireless Stereo (TWS) earbuds, for voice communications and calling on the move, often in loud public environments. Outdoors and wind noise, in particular, can severely degrade voice call clarity. V2S200D is designed to selectively pick up the speaker’s voice while suppressing all the other sounds, allowing for a comfortable and frustration-free voice call experience.

In addition to enhancing voice call quality, voice activity detection, imposter rejection, and personalization are some of the other use cases made possible by this sensor.

V2S200D, with its small size, high Signal-to-Noise ratio (SNR), and low power, offers an ideal solution to OEMs/ODMs looking to enhance the user experience of their products while working with significant Industrial Design (ID) and battery life constraints. In addition, upon integration into the system, it emulates a digital mic with Pulse Density Modulation (PDM) interface, which makes hardware and software development hassle-free.


SNR / 64.5 dB(A)
3.30 mm x 2.30 mm x 0.93 mm
Current: As low as 290uA




64.5dB Signal-to-Noise Ratio (SNR) in a small footprint 
High SNR & B/W for clear voice pick-up in loud/windy conditions
Low power consumption for always-on usage
50dB acoustic isolation in a noisy environment (bars, airports, windy outdoor spaces) 
Ease of integration from PDM interface; Stereo mode supported
