Abstract
The energy method for analyzing piezoelectric electro-acoustic transducers, described in the previous paper [B. S. Aronov, J. Acoust. Soc. Am. 117, 210–220 (2005)] is used here in application to transducers operating in the receive mode. Changes to the equivalent circuit of a transducer are introduced, arising from the action of the sound field considered as the external source of energy. The application of the energy method is demonstrated by an example of the circular flexural plate transducer. The validity of the single degree of freedom approximation for calculating the transducer parameters is considered, and estimation is made of inaccuracies arising from the simplifying assumptions regarding the mode of transducer vibration. The acceptable tolerance levels for accuracy in the calculation of the transducer parameters are also discussed.
