标题：手机声腔的模拟软件 -MICRO-CAP大家知道吗？
我所知道的声学模拟软件都是针对大口径的SPEAKER,有没有对小口径SPEAKER和所装配的腔体的模拟呢? 当然不是简单的出音孔大小,前后音腔的大小模拟的那么简单. 比如出音孔的形状,出音孔的位置,SPEAKER侧面出音对声音的影响,还有就是MIC声孔的位置,形状,通道等等对声音响应,响度,失真的影响
PHILIPS就是使用这个软件，但是只对频响和响度有仿真，其实这是用电力声的类比模拟出来的响应曲线和响度值。
熟悉这个软件的人可以多多交流！
有这么好的软件?
太好了!
有呀！ansys就可以，就是使用比较麻烦。
这些都挺贵的啊!
最好有免费的
,
而且比较复杂,不易操作.
贴一张micro-cap仿真曲线给大家看看，希望能起到抛砖引玉的作用
不好意思啊，不知道怎样才能贴上图

想知道这个软件设置详细的东西，哪位高手帮帮我：
1.speaker音圈作为电路的负载，音腔和音圈振膜等效成电元件，SPEAKER单体的参数需要输入系统吗？如F0，SPL等
2.测试信号是怎样模拟的？还有仿真嘴和耦合腔的参数是怎样计算进去的？
先说这两个吧。
先看一下等效电路的原理吧:

SPK的TS参数等需输入进去,F0 SPL等是计算(仿真)出来的.
仿真嘴和耦合腔的参数作为声负载直接并入等效电路中.
测试信号取20-20K的正弦扫频信号就可.
商业软件,哪里能共享?
似乎跟PSPICE差不多,也不是专为电声器件设计的.
