释义

Ribbon microphone

中文百科

铝带式麦克风

铝带式麦克风构造
美国哥伦比亚广播公司(CBS)使用的RCA 44系列铝带式麦克风

铝带式麦克风(Ribbon Microphone)是一种运用电磁感应原理的动态式麦克风,在磁铁两极间放入通常是铝或杜拉铝质料的带状金属薄膜,此薄膜受声音震动时,因电磁感应而生信号。

由于英文的Ribbon一词平时最常见的字义是丝带,因此也常被译成丝带式麦克风,其实原文这里的Ribbon并不是指丝带,而只是代表带状物。

Principle of operation

A ribbon microphone, also known as a ribbon velocity microphone, is a type of microphone that uses a thin aluminum, duraluminum or nanofilm of electrically conductive ribbon placed between the poles of a magnet to produce a voltage by electromagnetic induction. Ribbon microphones are typically bidirectional, meaning that they pick up sounds equally well from either side of the microphone.
