摘　　要：本文从封闭式扬声器系统的声学类比电路出发,推导了该系统的声辐射特性,并采用了变量轮换法这一多维最优化技术实现了封闭式扬声器系统的最优化设计。结果表明,计算曲线与实测曲线能很好的吻合。In this paper we present a new design method of adopting the optimum technique to select the parameters of the loudspeaker system. Based on the acoustic analogous circuits of the closed-box loudspeaker system, the mathematical model is established and the sound-pressure frequency response is derived. Thus the optimum designs of the lousspeaker system are computed by the use of one of the multiple-dimension optimum techniques. It is demonstrated by experiments that the mathematical model is correct, that the optimum technique is suitable, and that the agreement between the calcuated response curve and the measured curves is satisfactory.
