SonicEdge: Electrostatic MEMS Speakers SonicEdge is an Israeli-Danish MEMS speaker company developing ultrasonic amplitude modulation-based MEMS speakers for consumer devices. Founded in 2019, it focuses on replacing traditional voice coil speakers with silicon-chip solutions for applications such as TWS earbuds and AR/VR headsets. Many MEMS speaker companies are using piezoelectric transduction, but Sonic Edge has opted for an all-silicon electrostatic approach. IDTechEx spoke to Sonic Edge to discuss its product offering and core technology in depth. SonicEdge: Electrostatic MEMS Speakers
