The resonator of instrument has been studied by equivalent circuit to show the effect of coupling motion between membrane and resonator tube. From the analysis of motion and waves on the string, an expression for frequency response of vibration of string is given. This response has direct relationship with the reflection coefficient at the bridge. The reflection coefficient has been measured by using impulse method. The frequency characteristics of sound by bowing are dependent on two kinds of motions on the string. A method to obtain the sound spectra for Jinghu and Erhu by playing seven notes is presented in this paper.展开更多
