Abstract

A microelectromechanical loudspeaker. The loudspeaker includes a substrate, a housing arranged on the substrate, and a cavity delimited by the housing and the substrate. The loudspeaker includes a translation device, which is arranged in the cavity so as to be movable and deflectable in a specified movement direction parallel to the substrate surface and includes an arrangement of a plurality of movable fin structures, which are arranged next to one another in the movement direction and divide the cavity into a plurality of portions fluidically separated from one another, and a support structure connecting the movable fin structures to one another, and a drive device designed to deflect the translation device in the movement direction, including a plurality of drive units each including least one actuator electrode mechanically connected to the translation device and at least one stator electrode mechanically connected to the housing and/or the substrate.
