FIELD: acoustics.
SUBSTANCE: invention relates to acoustics. Acoustic piezoceramic transducer has a cylindrical housing in which there is a membrane around the circumference, having a flat and central convex part, in the base of which a bimorph piezoelectric unit with two piezoceramic disks connected by supply conductors, above the convex part of the membrane is fixed. Acoustic reflective screen with circular acoustic holes above flat part of membrane is fixed on housing by holders. At the same time reflecting acoustic screen is located above annular acoustic holes located on lateral sides of housing and above flat and convex parts of membrane, on outer side of acoustic reflective shield there is convex coordinator of acoustic oscillations.
EFFECT: technical result is increased acoustic pressure, efficiency, increased reliability and service life, increased strength of housing.
