Abstract
A sound transducer, including a diaphragm and at least one piezoactuator, which is situated in an operative connection to the diaphragm, the oscillation direction of the piezoactuator being situated at least generally perpendicularly in relation to the oscillation direction of the diaphragm, at least one lever element being situated between the diaphragm and the piezoactuator, which connects the diaphragm to the piezoactuator and is designed to convert oscillations of the piezoactuator into oscillations of the diaphragm and vice versa, and a clamp connection being formed between the at least one lever element, and the piezoactuator. The clamp connection is formed between an end face of the piezoactuator situated in the oscillation direction of the piezoactuator and the at least one lever element, and the piezoactuator is situated under an axial pre-tension force extending in the oscillation direction of the piezoactuator by the at least one lever element.
