主题：[原创]大家谈谈助听器受话器吧

材料,设计,测量等等,都可以谈谈!

1.The acoustic load consists of a BTE tube (8 mm x 1 mm ID + 28 mm x 1.5 mm ID
+ 25 mm x 2 mm ID + 18 mm x 3 mm ID) into a 2 cc coupler.

2.The acoustic load consists of ITE tubing 10 x 1 mm (or 5 x 1.4 mm) and a 2cc volume.

3.Receivers are usually specified on a 2cc coupler with BTE tubing or ITE tubing. Today there
are better representations of the human ear such as the B&K 4157 (IEC-711). In practice the
tubing may also be different. For example, in an ITE configuration the tube may be shorter
and wider than the 10 x 1 mm used for specifications.

楼主对受话器了解吗？想学习一下。

看这个曲线应该是声扬或者楼氏的动铁式受话器啊！

助听器用的受话器大部分是动铁式受话器.

动圈式可以用吗?为什么可以或不可以?

助听器用的基本是动铁的，效率高，灵敏度高!
动圈的一般是指带有助听设备辅助功能的受话器，加强通讯设备和助听器之间的兼容性！
