MEMS-Lautsprecher - ein Paradigmenwechsel

With the increasing demand for headphone-related audio reproduction, the requirements for the loudspeakers (transducers) have also increased. They should become smaller, lighter and cheaper, while requiring as little energy as possible to produce great sound. In addition to the two primarily used loudspeakers, namely the electrodynamic and balanced armature (especially hearing aids), so-called MEMS loudspeakers are being increasingly considered. Although history shows that MEMS loudspeaker concepts already existed in the 1990s, it was not until 2018/2019 that convincing demonstrators or finished products were equipped with them. Three current MEMS loudspeaker concepts are presented to demonstrate the great potential of this technology for the challenges mentioned above
