Abstract (en)
[origin: EP0327486A2] The object of the present patent application is a new type of radiator for sonic and/or ultrasonic frequencies consisting basically of a plate which has discontinuous profiles on both surfaces and which vibrates flexurally on excitation by a vibrator that may be piezoelectric, magnetostrictive, etc. in nature. The dual discontinuous profiles enable regulation of the amplitude and phase of the energy radiated, thereby achieving a high concentration of energy around a predetermined point.
