Abstract
The effect of end cap and PZT materials on the acoustic performance of Cymbal transducer was attempted. Generally there are three frequency bands of interest for identification of the objects in shallow and deep water environments. These are from 1 kHz to 10 kHz; 10 kHz to 100 kHz and 100 kHz to 1 MHz. Currently there is an interest in the lower frequency band and that can be addressed by using cymbal transducers. Cymbal is class V flextensional transducer, it consists of cylindrical ceramic disk sandwiched between two cymbal shaped metal caps with hollow cavities. Cymbals are used as both sound projectors and receivers. Finite Element Analysis (FEA) ATILA code was used to analyze the performance of sound projector and receiver. Three typical ceramic disks and materials used as driving elements and end caps respectively were included in this study.
