Knowles Corporation, a global provider of advanced micro-acoustic microphones and speakers, audio solutions, and high-performance capacitors and RF products, has released its first-of-a-kind Digital Voice Vibration Sensor, V2S200D. The sensor, designed to improve voice call quality in noisy environments, works alongside microphones to selectively pick up the speaker’s voice while suppressing all other sounds. This is achieved through blending low-band voice signals from the V2S200D with high-band voice signals using today’s True Wireless Stereo (TWS) microphones.
As consumers increasingly use audio devices like TWS earbuds for voice communication on the move, ambient noises common in public places present challenges for achieving high-quality communication with traditional noise suppression techniques. The V2S200D sensor is designed to solve these challenges and deliver a consistent, reliable, and frustration-free voice call experience in such environments. The sensor also enables other use cases such as voice activity detection, imposter rejection, and personalization.
V2S200D offers an ideal solution to Original Equipment Manufacturers (OEMs) and Original Design Manufacturers (ODMs) looking to enhance the user experience of their products while working with significant Industrial Design (ID) and battery life constraints. Its small size, high signal-to-noise ratio (SNR), and low power make it a suitable option for OEMs/ODMs. It also emulates a digital mic with Pulse Density Modulation (PDM) interface, which makes hardware integration and software development hassle-free.
Saket Thukral, Senior Director of Product Line Management for microphones at Knowles, said, “Frictionless communication from anywhere using Bluetooth headsets has become a basic expectation from consumers. We are excited to offer our customers an easy-to-use, high-performance solution to meet this expectation and help them delight consumers.”
V2S200D is sampling with lead customers and is expected to be in mass production later this year. According to Peter Cooney, Founder and Research Director of SAR Insight, “The unique solution provides remarkable performance, with low power, in a tiny package — the sweet spot for many applications in today’s market.”
