V2S200D vibration sensor selectively picks up the speaker’s voice and suppresses ambient sounds

Knowles Corporation (NYSE: KN), a market leader and global provider of advanced micro-acoustic microphones and speakers, audio solutions, and high-performance capacitors and RF products, releases the first-of-its-kind Digital Voice Vibration Sensor, V2S200D. Working in conjunction with traditional microphones, V2S200D—a high bandwidth, low-power specialized vibration sensor—improves voice call quality in noisy environments by picking up the speaker’s voice and rejecting ambient sounds, company leaders say.

According to the company, V2S200D is designed to help solve the challenges of voice call clarity in noisy environments and selectively pick up the speaker’s voice while suppressing all other sounds.

“Frictionless communication from anywhere using Bluetooth headsets has become a basic expectation from consumers. We are more on-the-go than ever, and the new ‘work-from-anywhere’ culture means dialing into conference calls from cafes, trains, and lounges,” commented Senior Director of Product Line Management for microphones at Knowles, Saket Thukral. “We are excited to offer our customers an easy-to-use, high-performance solution to meet this expectation and help them delight consumers.”

“Bone conduction sensors are fast becoming an essential feature in TWS designs to improve voice pick-up in noisy environments.” said Peter Cooney, founder and research director of SAR Insight. “Until now, solutions in the market have tended to deliver less-than-ideal performance or have been challenging to integrate due to their size, robustness, high power consumption, or some other significant trade-off. I had a chance to experience the new Knowles V2S200D sensor at CES 2023. The unique solution provides remarkable performance, with low power, in a tiny package—the sweet spot for many applications in today’s market.”

V2S200D is sampling with lead customers and is expected to be in mass production later this year.
