Abstract
An electroacoustic transducer, in particular a transmitting transducer for sonar systems, is disclosed, comprising two end caps that are arranged at a fixed distance from each other, multiple bars which are braced between the two end caps and the ends of which are attached to the end caps next to each other in the peripheral direction, and an elastic shell that externally encloses the bars. In order to significantly reduce the weight of the transducer and simplify production, composite modules are attached to the bars so as to excite vibrations. Each composite module has electrode structures that include spaced-apart electrodes and are arranged on at least two film layers made of insulating material, and spaced-apart piezoceramic fibers which are arranged between the film layers and are contacted by the electrodes on opposite longitudinal sides.
