品质因数(以下简称 Q 值),是反映扬声器低频特性的一个重要参数,它的计算方法有好几种,其中利用阻抗曲线来求解的方法比较简单,而被广泛采用。一般公式为;式中:Q:扬声器的等效品质因数;,f_0:扬声器的共振频率,Z_(max):共振频率点上的阻抗模值 Quality factor (hereinafter referred to as Q value) is an important parameter to reflect the low frequency characteristics of loudspeakers. There are several methods for calculating the low frequency characteristics of loudspeakers. Among them, the method of using impedance curves is relatively simple and widely used. The general formula is: Where: Q: The equivalent quality factor of the loudspeaker, f_0: The resonance frequency of the loudspeaker, Z_max: The impedance modulus at the resonance frequency
