HYDROACOUSTIC TRANSDUCER Russian patent published in 2015 - IPC H04R17/00 

FIELD: physics, acoustics.

SUBSTANCE: invention relates to hydroacoustics, particularly, to compact rod-like reinforced piezoelectric transducers to be operated with multielement antennas of hydroacoustic transceiving systems, for example, for sea underwater weapons. Claimed device comprises rod-like unit of piezoelectric elements, rear and face straps, bearing bulky fastening support element connected with the latter. Note here that face strap is connected by rod element extending with clearance inside rear strap cylindrical part. Said rear strap is connected by resilient spring conical circular element. Viscoelastic elements of acoustically soft materials are fitted in clearances above and below said resilient spring conical circular element.

EFFECT: efficient radiation, reduced effects of hydrostatic pressure at piezoelectric unit of elements and sensitivity to vibrations in reception mode.
