摘　　要：给出了推导通用公式的一种新方法,简要论述了如何利用阻抗曲线求解扬声器参数,粗略分析了阻抗曲线的对称性和Q值产生偏差的原因,提出了减小偏差的建议,明确了Q与γ1,Δf之间的关系,精确算出了额定阻抗及对应频率。A new method to derive a general formula is described. How to use the impedance curve to compute parameters of loudspeakers is briefly discussed, and the symmetry of impedance curves and the cause for the deviation of Q is roughly analyzed, a proposal to reduce deviation is given. The relationship between Q and γ1 ,△f, is specifically defined, and rated impedances and their corresponding frequency are accurately calculated.
