摘要 仿真耳(IEC711 coupler)广泛地应用于手提电话、耳机等的电声性能测量;介绍了利用有限元方法来获得IEC711 coupler的频响仿真,从而可以给出比等效线路图方法(LPM)更为真实的分析。 Ear simulators (IEC711 coupler) are widely used in measuring the electro acoustic performance of mobile phones and earphones. The frequency response of IEC711 coupler using FEM is presented, and the result can be more realistic than that using LPM.
