| Abstract: | In this paper,the overall frequency equation of the sandwich transducer is restudied using the equivalent circuit of the transducer,and the matrix expression for the overall fre- uency equation is derived,which proves to be useful,in the design of this type of transducers. By means of this equation,we discussed the relationship between the electroacoustical efficie- ncy and the geometric parameters of this type of transducers.The discussions mentioned above provide a theoretical basis for the rational designs of sandwich transducers. |
