Making a dynamic microphone

ku5o · 25th January 2006, 05:21 PM

Hello,

I've searched around and am wondering if someone can help me create this:

I am a school teacher and want to show my kids the current that a diaphragm creates in a dynamic microphone.

I have never created one and was hoping someone could give me a basic material list to demonstrate this. I don't need to record the sound or anything, just want the voltage detected from the coil and magnet.

Thanks for the help!

HI Ku5o

Why not to use a little speaker from a old radio. A speaker make a useful microphone , if fidelity is not a issue.

Regards.

hi ku5o

i have a bunch of spare dynamic microphone guts if you want
all you have to do is solder a pair of wires to it and hook it up to milivoltmeter
the needle will move as you speak to it
