METHOD OF EXCITING HYDROACOUSTIC WAVEGUIDE CONVERTER AND DEVICE THEREFOR Russian patent published in 2015 - IPC H04R17/00 H04R1/44 B06B1/06 

FIELD: physics.

SUBSTANCE: excitation of a waveguide converter includes a process of converting electrical energy into the energy of a leaky wave propagating in an elastic waveguide. Wave excitation is carried out with a rod-shaped piezoelectric bundle, inversely placed inside a hollow gas-filled cylindrical waveguide, and inversion of the front of the longitudinal wave in space is provided by reflection thereof from the external unloaded surface of the matching cover plate.

EFFECT: providing a directed acoustic field with a low level of reverse radiation, operation in a wider frequency band while maintaining reversibility, high sensitivity and radiated power, considerable reduction of weight and size.
