FIELD: acoustics.
SUBSTANCE: invention relates to acoustics, particularly to a piezoelectric electroacoustical transducers. Electroacoustical transducer comprises an alternating voltage generator, a cylindrical body coaxially disposed therein, a circular bimorph with two piezoelements, fastened with a convex membrane above it and a common flat annular holder, is equipped, over the convex membrane, with an acoustic reflective screen with peripheral nodes to coaxially fasten the transducer to the cylindrical body.
EFFECT: technical result is increased acoustic pressure by 2, narrowing of acoustic oscillation emission pattern, increased efficiency, increased action range.
