MEMS microspeakers for the future of the mobile internet

The microspeakers for wireless in-ear headphones from Arioso Systems GmbH, a spin-off of the Fraunhofer Institute for Photonic Microsystems IPMS, are up to ten times smaller than conventional microspeakers and are made entirely from silicon. Currently at the prototype stage, the energy-efficient micro-electromechanical system (MEMS) speakers may in future play a role in expanding the range of functions offered by miniaturized headphones—such as instant translations and health monitoring features. This is made possible by an innovative sound transducer principle that dispenses with the membrane, the central element of a conventional speaker.
