Inline microphone

  1. Mar 29, 2015 #1
    In a standard set of headphones, the inline microphone only has two leads, ground and hot. I took a multi-meter to the microphone input of one of my devices and there was 1.7V DC waiting.

    So I'm wondering how such a microphone operates (just that type of mic in general). I searched online for a diagram, but no success. Does it vary the 1.7V DC that's fed into it?

    Also, what output voltage are those inline mics usually at?

    Thanks
