CYLINDRICAL ELECTROACOUSTICAL TRANSDUCER UTILIZING BENDING VIBRATIONS Russian patent published in 2008 - IPC G01S7/52 B06B1/06 

Abstract SU 1840658 A2

FIELD: piezoelectrics.

SUBSTANCE: piezoelectric cylindrical transducer according to inventor's certificate #1840660, in which sections located in the section area along the cylinder generators, the radial vibration velocity of which is equal to zero, are made of a (piezoelectrically) passive material (e.g., a metal), the mechanical properties of which are close to those of the active material.

EFFECT: increase in acoustic mechanical efficiency of transducer without changing its specific sensitivity.
