contact microphone

基本解釋

Throat microphone is highly immune to environmental noise because of its close contact with the throat skin.
喉部送話器直接感受聲門處皮膚的振動(dòng)，不經(jīng)過空氣傳導(dǎo)，因而具有很強(qiáng)的抗環(huán)境噪聲干擾的能力。
This is their second effort to make contact with the men. Yesterday a microphone was lowered down to a separate hole, but that also turned up nothing.
這是他們第二次嘗試和礦工聯(lián)系，昨天一個(gè)邁克風(fēng)放在另一個(gè)洞里，但也沒有結(jié)果。
