MEMS loudspeakers for mobile communication devices

Prototyp of a MEMS-Actuatorship

In collaboration with partners from industry and science Fraunhofer ISIT is developing a new generation of miniaturized loudspeakers, which are fabricated using silicon technology. In contrast to conventional electrodynamic micro speakers the new chip speakers are based on powerful piezoelectric MEMS drives and feature high energy efficiency and extremely low fabrication tolerances. Fields of application are mobile communication devices like tablets, smartphones and headphones.
