Applications of the Method for Transducer Transient Suppression to Various Transducer Types

Abstract

Recently, a new method for suppressing the transient pressure radiation ordinarily produced by a projector in response to drive turn on and turnoff has been described J. C. Piquette, 'Method for transducer transient suppression I. Theory,' J. Acoust. Soc. Am. 92, 1203-1213 (1992) and 'II. Experiment,' J. acoust. Soc. Am. 92, 12141221 (1992). The experiments described in the earlier reports involved application of the method primarily to piezoelectric spherical transducers, although one preliminary application to an array of piezoelectric tubes was also considered. The present work involved the application of the method to a variety of transducer types to which the method had not been applied previously. These types are (1) flexural disk, (2) Helmholtz resonator, (3) moving coil, (4) inductor-tuned Tonpilz, and (5) a dual transducer array of piezoelectric squares and disks. A high degree of transient suppression was observed in all units that were tested. Equivalent circuits useful for designing the transient-suppressing drive are also provided.
