Abstract
The transducer is formed of at least two metallic blocks (3) with at least one layer 3 of piezo-electric material sandwiched between these metallic blocks, the faces of the layer or layers being metal sprayed to conduct the voltage. One metallic block has at least one projecting element reaching to the opposite metallic block and being connected with the opposite block by means of a binder. Stresses are generated between the layers of piezo-electric material and the metallic blocks originate in the piezo-ceramic material. The faces of contact between the metallic blocks can be either slanted or perpendicular relative to the layers of piezo-electric material. The projecting elements can be made either as dowels or as collars. Oscillations in the transducer are excited by a voltage applied to the transducer terminals.
