标题: 哪位高人能给科普一下SILYNX C4OPS 这个东西 [打印本页] 作者: blackhawk1985 时间: 2013-4-23 21:02 标题: 哪位高人能给科普一下SILYNX C4OPS 这个东西 看了一些资料,也去了官网,官网介绍说是有降噪和辨别声音方向的功能,但是感觉这个C4OPS就是个多路信号传输器,没明白是怎么起到降噪和拾音功能的,耳机貌似也只是个耳塞啊?
下面是官网的资料,望高人指点:

看过了,只讲了与对讲机的兼容性,没有它耳机降噪拾音的测试,我就想搞明白它一个小耳塞怎么降噪拾音的作者: jason-lee 时间: 2013-5-3 19:14
原理极其简单,把传统耳机上的"拾音降噪"组件做到那个硕大的PTT一起了而已,耳机只是一个声音传输终端,包含的只是声音采集和发送功能,对声音进行处理的工作交给和PTT在一起的那些部件去完成了。作者: blackhawk1985 时间: 2013-5-5 22:04
不知这东西能不能当手机的耳机用呢?有点浪费哈哈作者: jason-lee 时间: 2013-5-5 23:29
