STMicroelectronics and Austrian company USound GmbH announced their collaboration on the industrialization and production of the world’s first miniature piezoelectric MEMS 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.
Manufactured using STMicroelectronics’s industry-leading thin-film piezoelectric (TFP) technology, these actuators will improve scalability and cost while assuring lower power consumption and heat dissipation in hearables and smartphones devices, without compromising audio quality.
USound and STMicroelectronics anticipate the piezoelectric MEMS actuator will move into production in Q3 of this year and will be shipping in consumer products by the end of the year.
