Abstract

A micromechanical functional apparatus, particularly a loudspeaker apparatus, includes a substrate having a top and an underside and at least one circuit chip mounted on the underside in a first cavity. The apparatus further includes a micromechanical functional arrangement, particularly a loudspeaker arrangement, having a plurality of micromechanical loudspeakers mounted on the top in a second cavity. A covering device is mounted above the micromechanical functional arrangement on the top. An appropriate method is implemented to manufacture the micromechanical functional apparatus.
