Abstract SU 1840749 A1

FIELD: physics, communication.

SUBSTANCE: wide-band transducer comprises active element made of piezoelectric cells set, passive rear and emitting cover plates, reinforcing element and matching element. Matching element is also made as active from set of piezoelectric cells, and active element is equipped by transitional cover plate. Matching element is installed between transitional and emitting cover plates and is electrically connected to active element. Reinforcing element is made as separate for active and matching elements.

EFFECT: provision of specified irregularity of transducer frequency characteristic in working range of frequencies and possibility of its adjustment.
