FIELD: acoustics.
SUBSTANCE: invention relates to acoustics, in particular to electro-acoustic piezoelectric transducers. Electroacoustic piezoceramic transducer, comprising a body, coaxially sequentially fastened diffuser holder, diffuser and packages of two piezoceramic bimorphs with interbimorph binding nodes, the transducer is characterized in that between the top of the diffuser and the body, with the help of central fixing racks, two or more packages, each of them consisting of piezoceramic bimorphs connected along the periphery by binding nodes, are fixed, separated by a central fixing rack, electrically connected in such a way that when applying an alternating voltage of a predetermined frequency, piezoceramic bimorphs in packages bent in opposite directions, transferring mechanical vibrations to the top of the diffuser with amplitude, equal to the sum of the vectors + h of all piezoceramic bimorphs.
EFFECT: technical result is an increase in the acoustic pressure and an increase in the efficiency of the device.
