HYDROACOUSTIC TRANSDUCER Russian patent published in 2009 - IPC G01S7/52

Abstract SU 1840705 A1

FIELD: physics, acoustics.

SUBSTANCE: hydroacoustic transducer comprises active piezoceramic section with radiation and rear cover plates, passive reinforcing rod and elements for fastening to power plate. Passive reinforcing rod is made as composite and is separated by support flange installed in its nodal plane and rigidly fixed to elements of fastening to power plate. At that ratio of length of rod part inverted to emitting cover plate to length of rod part inverted to rear cover plate, lies within the limits of 0.8 : 1.0.

EFFECT: higher electromechanical coupling factor and reduction of body vibrations effect at transducer operation.
