Microelectromechanical loudspeaker with a large-area force field

A microelectromechanical loudspeaker, comprising:

• a substrate with a substrate surface;
• a housing arranged on the substrate;
• a cavity delimited by the housing and the substrate;
• 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;
• a drive device configured to deflect the translation device in the movement direction, the drive device including a plurality of drive units including a plurality of actuator electrodes, wherein each of the plurality of drive units includes at least one actuator electrode of the actuator electrodes, mechanically connected to the translation device, and each of the plurality of drive units includes at least one stator electrode mechanically connected to the housing and/or the substrate, wherein the at least one actuator electrode and the at least one stator electrode assigned to each of the drive units are configured to, when they are subjected to different electrical potentials, generate an electrostatic force that accelerates the translation device in the movement direction;
• wherein at least some of the actuator electrodes are arranged on the support structure.
