SPEAKER CHIP USES ULTRASOUND TO CRACK VOLUME LIMITS

Summary from the TLDR newsletter

xMEMS is a five-year-old startup that specializes in making speakers from microelectromechanical systems (MEMS) silicon-and-piezoelectric chips. Its designs have many advantages over other miniature speakers. A new technology designed by the company uses ultrasonic modulation and demodulation to create pressure and generate sound. This article covers MEMS systems and explains how xMEMS' ultrasound system works.
