STMicroelectronics To Manufacture USound's Patented Thin-Film Piezo-Electric MEMS Micro-Speaker Technology
STMicroelectronics and Austrian company USound GmbH announced their collaboration on the industrialization and production of the world's first miniature piezoelectric MEMS (Micro-Electro-Mechanical Systems) actuators for smart audio systems in portable devices. The patented micro-speaker technology from USound aims to replace commonly used balanced-armature and electrodynamic receivers for handsets with a small piezo-MEMS actuator.
