The German Fraunhofer Institutes for Digital Media Technology IDMT and Silicon Technology ISIT caused a stir at the Jahrestagung für Akustik DAGA (the annual conference of the German society for acoustics) in Munich from March 19 to 22, 2018. They presented the first integrated MEMS-based micro speakers to industry representatives and experts. The MEMS speakers will be used in future mobile communication devices, headphones, and hearing aids. With an area of just 4x4 millimeters, they cover the complete frequency range from 20 Hz to 20 kHz as a one-way system and achieve a sound pressure level of 110 dB for in-ear applications.
