| 摘 要： | In this paper, the dynamic properties of the main sounder (the sounding muscle (SMc) and the sounding membrane (SM)) and the generating mechanism of amplitude-modulation pulse train (AMPT) are given. The acting process of SMc is a quasi-simple harmonic contraction vibration. The amplitudes of soundless and sounding contracting motion are about 17.2 /μm and 29.4/μm, respectively, and the efficiency of dynamic sounding is about 17％, The unsounded motion of SM is a quasi-simple harmonic vibration, and the amplitude is about 7.81/μm. The sounding motion of SM is a complex vibration, and the amplitude is about 12.66 μm. In each syllable of the song, AMPT_(1,2,3) are separately produced by driving vibrations (V_1,2,3)) of three long ribs in the upper half of SM, and the peaks of V_(1,2,3) lead the first pulse of high amplitude in AMPT_(1,2,3) by 0.156 ms, respectively. The membrane structure in the lower half of SM is mainly to transmit contracting movement of SMc.
