摘　　要：针对手机音频入网时对听筒音量和音质的要求,说明了音频入网时采用的仿真耳的耳型差异,分析了手机听筒选型和听筒音腔设计的3种方案,编写了软件进行仿真。通过软件仿真和实际测量,验证了方案的合理性,将通话时使用者的主观感受与入网要求值对应起来。In order to meet the acoustic requirement on receiving direction of mobile phone, the differences of simulator ears are discussed. Several solutions of receiver choice and mechanical design are analyzed. A software is given to simulate the acoustic performance of different mechanical designs on different simulator ears. Measurement and simulation show that mechanical designs are good for both subjective and objective acoustic performance of mobile ohone.
