Abstract
With regard to the mathematical treatment of piezoelectric transducer, the conventional framework using Mason´s equivalent circuit and a new method termed ´complex series dynamics´ are compared from the viewpoint of energy in the transducer. In the latter method, precise evaluation of resonance intensity and frequency can be performed. In addition, conventional and new frameworks to treat a shift of acoustic speed are outlined.
