Receiver声腔设计 Speaker声腔结构设计Receiver声腔设计
主要指手机内部所构成的声腔或者泄漏孔对Receiver的性能或者声音产生的影响，如下图所示，声孔、前腔、内腔、泄漏孔等等都会对手机的整机音质表现产生影响，首先要用RubberRing，即环形橡胶垫把Receiver与手机外壳密封起来，使声音不会漏到手机内腔，然后就是声孔、前腔、内...

仍然有胶…… 还好，用镊子挑断热熔胶拉成的丝
完整分开了：
那块透明塑料又是用热熔胶固定的，显得太low了。原型这么弄弄就罢了，产品里面能做得大方点么？
取下来，下面又有螺丝孔了。
但是我拧下螺丝还是没有能继续拆下去。后面是声腔，就只有speaker在里面了，不拆也罢。
回头再看麦克风，4mm直径的ECM. 热熔胶是为了固定麦克。
