摘要
本文根据测试传声器的等效类比图和各声学元件的典型的和估算的参数,利用计算机进行辅助分析,找到了影响传声器低频相位特性的主要因素。并验证了B/K提出的附加声学结构后相位特性的变化,为声强探头的相位控制提供了依据。
According to the equivalent analogous circuit of microphone and the typical or estimated parameters of each acoustical element, the main factors affecting the phase characteristics of microphone at low frequencies are found by means of CAA. And, by additional acoustical structure proposed by B/K, the variations of phase characteristics have been verified, the basis for the phase control of the probe is given.
