Vesper Introduces Analog Piezoelectric Voice Accelerometer for True Wireless Earbuds

Vesper introduced the VA1200, which the company calls the world’s first analog piezoelectric voice accelerometer (a.k.a. bone conduction sensor). This low-power vibration sensor can be used in true wireless earbud designs to pick up the wearer’s own voice through bone conduction. Using the VA1200 in conjunction with a standard microphone and a sensor fusion solution, the application can achieve superior background and wind noise reduction. Vesper calls this combination OnePlusOne.

SAR Insight & Consulting Forecasts Technology and Market Potential for MEMS Speakers

MEMS microspeakers and earphone drivers could threaten incumbent audio technologies by 2025 as consumers desire smaller and less power-hungry devices. Four billion devices with seven billion speakers were shipped during 2020, it has been estimated, across multiple sectors, including automotive, mobile phones, home AV, and many others. MEMS speakers could revolutionize the audio industry, thanks to their small form factor and low power capabilities, according to market analyst SAR Insight & Consulting.
