摘　　要：本文由无源体扬声器系统的声学类比线路出发,导出了该系统的声压频率响应函数,并用Rosenbrock算法,求出系统的基本参数,以达到所期望的性能。实验表明,计算曲线与实验曲线的吻合程度是令人满意的。In this paper we have derived the sound-pressure/ frequency response function from the acoustic analgous circuits of the passive-radiator loudspeaker system. We have also selected the basic parameters of the loudspeaker system using the Rosenbrock method to achieve some desired performance. It is demonstrated by experiments that the agreement between the calculated response curves and the measured curves is satisfactory.
