Abstract:
A digital loudspeaker and a method for operating a digital loudspeaker are disclosed. In an embodiment a digital loudspeaker includes a substrate, a first stator fixed with respect to the substrate, a second stator fixed with respect to the substrate and spaced at a distance from the first stator, and a membrane between the first stator and the second stator. The membrane is displaceable between a first position in which the membrane mechanically contacts the first stator and a second position in which the membrane mechanically contacts the second stator. The first stator and the second stator are arranged to electrostatically move the membrane from a rest position spaced apart from the first position and the second position to the first position and the second position, respectively.
