中文摘要:
      文章论述了运用遗传算法优化设计两分频扬声器分频网络的方法。使用实测的扬声器阻抗、频响数据,模拟扬声器接入分频网络后扬声器系统的响应,并运用遗传算法对系统响应进行优化设计。文中给出的实例表明,设计结果和实测的曲线是一致的。
英文摘要:
      In this article,a method to design two way loudspeaker crossover networks by genetic algorithms is described. The measured sound pressure frequency response and the impedance frequency response of the woofer and the tweeter are used to simulate the response of the system when the loudspeakers are connected to crossover. The component values of the crossover are selected by genetic algorithms such that some responses are optimun. A design example shows that the calculated and measured frequency response are accordant.
