METHOD OF RADIATION OF ACOUSTIC WAVES AND DEVICE FOR ITS IMPLEMENTATION Russian patent published in 1996 - IPC

FIELD: ultrasonic and pulse equipment. SUBSTANCE: method is intended for radiation of acoustic waves into liquid or gas medium, specifically, for local acoustic action at small distances. Radiation of acoustic waves occurs thanks to piston action carried out by excitation of elastic waves with vertical polarization 3 in walls 1 of channel 2. For increased radiation efficiency thickness of walls 1 of channel 2 should not exceed length of excited elastic wave and surface of contact of oscillation exciter with elastic element has bevel. EFFECT: increased radiation efficiency. 4 cl, 5 dwg
