Abstract

The invention relates to a sound transducer for producing sound vibrations, which can be inserted in an ear and can be used in particular for an implantable hearing aid. The sound transducer has at least one carrier layer and at least one piezoelectric layer, as a result of which a deflection via a bimorph principle is achieved, or a deflection can be detected by picking up a voltage.
