    摘要: A method of manufacturing high power sandwich type ultrasonic transducers and, more particularly, a new method of tuning high power sandwich type ultrasonic transducers without the need for a trimming process. A method in accordance with the present invention includes the steps of assembling a sandwich type ultrasonic transducer, measuring the resonant frequency of the ultrasonic transducer, and selecting from a plurality of tuning elements, whereby a dimension or material property of a selected tuning element alters the measured resonant frequency of the ultrasonic transducer to a desired resonant frequency after the tuning element is attached to the ultrasonic transducer.
