  • In this paper a transformation net matrix is used to represent the characterastics of each vibrational part of a transducer, and the in herent relationship between mechnical quantities (velocity and force) and electrical quantites (voltage and current) is determined. Since matrix coefficients are the function of klk is wavenumber and l is the length of each part) after adjusting the length in proportion to frequency while keeping kl to be a constant the produced new transducer will reserve all the characterastics of the original reference transducer. Its changed performance parameters can be obtained by using a conversion proportional factor. Thus this paper offeres a convinient method and corresponding theoretical base for designing longitudinal vibration transducer. At the end a practical example using a general purpose design program is tested.
