Abstract
A device for transmitting ultrasonic energy to a liquid or pasty medium, comprising an alternating current generator ( ) intended to operate in a frequency range of 1 to 100 kHz, a magnetostrictive or piezoelectric transceiver ( ) capable of producing under the generator output AC voltage longitudinal high frequency mechanical vibrations, a waveguide ( ) in the form of a cylindrical rod capable of being stimulated by said transceiver for generating longitudinal harmonic vibrations, and a cavity resonator ( ) acoustically coupled with the waveguide and in a tubular form for converting said longitudinal harmonic vibrations into transversal vibrations relative to the longitudinal axis ( ), the wave power of which can be injected into the medium to be submitted to sonicating. Said cavity resonator ( ) is designed in such a way the resonance requirement is met both for the longitudinal and transversal self-vibrations of its envelope ( ).
