摘要
Recently, it has become important, with the development of electroacoustic devices, to provide a systematic analysis of the electrical circuit, the electromechanical transducer part and sound field, taking their interactions into consideration. This paper presents a numerical method of computation for the electrical circuit, transducer part and sound field, in which the entire system is represented by an electrical equivalent circuit. A formulation is made of the wave propagation and circuit element characteristics of Bergeron's method, with the time-axis analyzed by the node equation.
