Abstract

New electroacoustic unit for the efficient generation of high sonic and ultrasonic intensities in gas media and in interphases (gas-solid, gas-liquid). Said unit is comprised of an electromechanical transducer system of which the radiating element is a plate (3) having a discontinuous profile and an electronic device for the controlled generation of the electric power signal. The unit is capable of generating acoustic fields of very high intensity with a predetermined configuration. Particularly it is capable of generating with a same transducer system two distinct configurations of the acoustic field. Prototypes for generating directional and focused fields have been developed.
