An actuator, including an electric drive for converting electrical signals into mechanical forces and/or deflections. The drive having at least one coil through which the current of the electrical signal can flow and having at least two magnets which can electromagnetically interact with the coil. The actuator being designed to excite a body which can be connected to the actuator, in particular a flat body, to vibrate, as a result of which the body can emit acoustic sound. The two magnets are arranged such that they form a substantially straight air gap between them, the coil being arranged in the air gap.
