World’s Smallest MEMS Micro-Loudspeaker Saves 80 Percent More Energy

STMicroelectronics along with the audio company USound has created the first MEMS (Micro ElectroMechnical Systems) micro-loudspeaker based on semiconductors. It’s the smallest loudspeaker in the world, but it can produce a powerful noise. MEMS makes it possible. The speakers are being presented at CES 2018 in Las Vegas. In the audio world, the electromechanical capabilities of MEMS have only been used to bu ...
