Abstract
A vibratable diaphragm (1) having passive tightened single layers of isotropic or anisotropic layers with active function elements (4) formed as a multilayer bond, is held in a holder (2). The diaphragm accepts deformation energy for different stable equilibrium positions, the change in which causes sound.
