手机音频设计1、二个SP最小间距： 立体声是由不同的声道馈给不同的SP于不同的音频信号，使每个SP发出不同的声音，使人有声音是由不同的声源从各个位置传到人耳当中的感觉，产生空间立体概念。以2个扬声器为例，首先要满足等边三角形原理，即La=Lb=LC事实上手机中La<<Lb、 LC相当于两个重叠点声源，因此手机当中不可能达到传统意义上的立体声效果。只能尽量使LA大，尽量提高SP立体声效果。（就是三星的乐趣CDMA1××619，他自己也只是宣称具备虚拟三维环绕立体声）我自己感觉他是在声频信号处理方面下的文章。2、2个SP的选用与匹配 一、若选用高、低音SP：电路具有分频功率能，同时微型电声元器件，高低音SP也很难达到通用音箱的效果，因此建议用一样的SP。 二、SP串、并联问题：串、并联阻抗成倍数变化，对电路的功率、电流产生很大影响。 三、相位问题：两个SP相位必须相同，SP须注明正负极（单个SP无所谓相位相同）；否则两个相位不同的声波会发生干涉，可能会叠加成与输入声波相差很远的声波信号。 四、屏蔽问题：要求SP一致性非常好，频响曲线相差不能超过2dB，否则声音声音较大的那个会把另一个屏蔽扣掉，人根本听不到声音较低的SP发出的声音；两个同样的SP叠加，响度会增加3dB。3、单个SP腔体设计：腔体d×h，受手机体积限制，d×h距理论最佳小很多，d，h越大声音效果会越好。4、两个SP 摆放高度差问题：手机当中的这个差值，相对声波波长与声波的传输速度来说，影响很小，可以不用考虑。手机实现的立体声，与传统意义上的立体声实现的途径估计应该不同，手机当中可能更倾向于在电路中对声频信号进行处理，达到一种虚拟的立体声环绕效果。
