直板机的听感与MIC和RECEIVER的腔体有很大关系,特别是MIC的,有谁总结过吗?

φ13Receiver:    声孔总面积约3mm2   前腔高度0.2mm-0.8mm  泄漏孔总面积约5mm2  内腔体积约4cm3。    φ15Receiver:    声孔总面积约3.5mm2  前腔高度0.2mm-0.8mm  泄漏孔总面积约5mm2 内腔体积约5cm3。

从供应商处获得的信息,设计音腔时可以咨询一下相应的供应商,他们一般会给有一些建议[br]<p align=right><font color=red>+5 RD币</font></p>

1.影响手机音乐效果因数:腔体,喇叭,音源,IC芯片;
音腔结构:前后音腔,出音孔
  要使音乐效果较好,最好同时设有前音腔和后音腔,二者一定不能互通,音腔密封性还要好,且前音腔要窄,后音腔要宽,这样才能充分表现高低音的效果.

2.SPEAKER设计要求:
1>出现破音--->音腔太薄(厚度),应选择尽可能大的尺寸;
2>塑胶壳上开数个出音孔时,各出音孔的面积总和应不小于SPEAKER有效发声面积的20%为好;
3>出音孔位置不要开在发音区域的中心位置;
出音孔尽量开在边缘,利于声音在音腔内扩散;
3>勿开细长状出音孔,以水滴状为最好;
4>音量太小的原因分析:
     SPEAKER功率太小-->最好>0.5W
     SPEAKER直径太小-->最好>15MM
     SPEAKER本体厚度-->不低于3.3MM
5>其它:
   出音孔直径或宽度应控制在1.5mm~2.5mm以内,绝对避免狭长缝作为出音孔;
   声腔设计深度0.8mm~1.0mm,较佳取值1.0mm;
   前音腔体积过小易”嘶叫”;
   声压级越高,SPEAKER声音越宽;
