Equivalent Circuit Analysis for Tonpilz Piezoelectric Transducer
Summary :
Tonpilz piezoelectric transducers are one style of transducers for high-power sound generation. However, the transducers have mainly been designed by the trial-and-error method. The object of this paper is to precisely estimate the transducer performances beforehand by a equivalent circuit analysis. The precise electro-mechano-acoustical equivalent circuit is derived for the transducer, including housing, an acoustic rubber layer and a bolt, and its transmission matrix is presented. To improve the calculation accuracy, the effects of adhesive layers in a piezoelectric ceramic stack part and compressive stress by bolting them together are included into the electrical and mechanical equivalent constants for the ceramic stack. Also, to accurately evaluate any errors between theoretical values and measured values, transducer performances are expressed as absolute values by MKS units. Then, based on this analysis, a Tonpilz transducer has been built. Transmitting and receiving voltage sensitivities for the transducer, as well as the respective resonant frequencies, mechanical quality factors and free admittance loci in air and in water, have been measured. As a result, a good agreement between theoretical values and experimental results has been achieved.
