ABSTRACT:
An electro-acoustic transducer has a transducer plate having a piezo-electric layer attached thereto. The electro-acoustic transucer is clamped between bearing members at an annular edge region which is free of the piezo-electric layer. The piezo-electric layer is provided with electrodes which extend into the annular free region of the transducer plate. At least one of the bearing members has electrically conductive zones which press directly or indirectly against the electrodes and which press against electrical plug elements on a housing for the transducer.
