A new-style, piezocomposite cymbal transducer is presented in this paper. The single cymbal element is packaged in an ultra-high frequency (UHF) connector and sealed with epoxy, plugged by a coaxial-cable, which is more portable and miniature compared with conventional ones. Several kinds of cap heights are designed and the theory model of class V flextensional transducer is used to study their performance based on the cavity depth and caps thickness. The effect of dimensional changes on fundamental resonant frequencies has been investigated by finite element analysis. It is found that the cymbal transducer exhibits large displacement amplification, fast response time and high effective coupling factor through theoretical calculation, which are coincident with measurements. The results show that this design would have more potential application of low frequency and high energy transmission.
