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.
