| 摘要 |
This invention relates to an ultrasonic generator apparatus for generating and transmitting enhanced ultrasonic wave energy of a predetermined frequency to a liquid confined in a container which contains a resonance enhancing disc. Such electroacoustic transducer apparatus or generators are utilized in ultrasonic cleaning equipment. The apparatus are mounted to the side or the underside of the liquid container or mounted in a sealed enclosure which is immersed in a liquid in a container made of metal, plastic or glass. Generators are used in single or plurality of to energize the liquid with sonic energy which in turn transformed into cavitations. In the present invention, the insertion of a resonance enhancing disc between the base of the generator and the piezo electric material provides an increase in intensity of the resonant frequency signals, diminishing periodical shift in frequency and stabilizing piezo electric material temperature.
