Abstract
An actuator, including an electric drive for converting electrical signals into mechanical deflections, the drive having a coil through which the current of the electrical signal can flow, and having a permanent magnet which can be in electromagnetic interaction with the coil, the actuator furthermore has a housing and a flat body, the flat body being able to be mechanically deflected and/or mechanically excited into vibration by the electric drive and, in the process, being able to radiate acoustic sound signals, wherein the flat body is connected integrally to at least part of the housing and at least part of the drive is connected to the flat body.
