- Enables a drastic improvement of voice quality in earbuds, AR glasses and True Wireless Stereo (TWS)
BOSTON – (March 28, 2022) – Vesper, a global MEMS supplier of the most advanced piezoelectric sensors, today continues to redefine the intelligent edge with the launch of the VA1210, Vesper’s 2nd generation analog piezoelectric smart voice accelerometer. The VA1210 offers higher sensitivity (+17 dB) and higher (+6 dB) SNR than the 1st generation VA1200 in voice pickup. Additionally, new intelligent features of Wake-on-Voice (WoV) and hardware voice activity detection (HVAD) are introduced into the VA1210.
With WoV, the VA1210 can continuously monitor the TWS wearer for voice activity via bone conduction while consuming a scant 10 µA of current thanks to Vesper’s patented ZeroPower SensingTM (ZPS) technology. The VA1210 can accurately detect voice activity and only power on the system processor when voice is present. This gives TWS and other system designers the opportunity to dramatically cut average power consumption.
Like the 1st generation VA1200 the VA1210 retains the superb immunity to ambient sounds, and only picks up the user’s voice. In addition to being used as a bone conduction mic, the VA1210 is a superb low noise, high bandwidth, low power accelerometer for detecting vibration in IoT, Automotive and industrial applications. Our ZPS engine can be programmed to ideally suit the desired use case. Examples of applications include, large area touch sensing, machine monitoring, leak detection and many others.
The VA1210 comes in the same tiny package (2.90×2.76×0.9mm3) as the VA1200. The VA1210 has differential analog output allowing more robust hardware designs. It is reflow solder compatible with no sensitivity degradation.
“The VA1210 provides the ideal trade-off between performance, power consumption and cost. The ZeroPower SensingTM engine allows hardware designers to improve the system efficiency and drastically reduces software development time. With the proliferation of TWS, AR/VR and IoT devices we expect to see a lot of adoption of VA1210 in the market,” said Senior Director of Marketing Roberto Condorelli.
Target applications for the VA1210 include: Earbuds, TWS (True Wireless Stereo), VR (Virtual Reality), AR (Augmented Reality), Smart-frames and Smart-glasses, industrial, automotive and IoT devices.
VA1210’s disruptive features in the TWS application: High-Fidelity VPU, Automute™, Tap Detection, Voice Authentication.
