"AT&S is a technology partner of USound. Development of the MEMS micro-speaker would not have been possible without innovations in materials, silicon integration and packaging. Thanks to state-of-the-art packaging solutions, the MEMS loudspeaker itself, its drive circuits (application-specific integrated circuits, ASIC) and passive elements can be integrated into a tiny component with an extremely small form factor."
