im sure most of you have small stereo speakers laying around the house that are broken or just useless to you. but a cool thing about speakers and microphones is that they are practically the same thing. in this simple instructable i will show you how to use ANY speaker as a mic.
*note: headphones work too*
Materials needed:
XLR cable
1xDecent sized speaker

Step 1: Strip Your XLR Cable

the first thing you need to do is strip your XLR cable. inside the cable you should find a positive wire, a negative wire, and a ground (the only wire that doesnt have rubber around it. this wire will not be used"
<p>Good job! Definitely easy for scavengers. I'm assuming you can connect it to a standard audio jack as well. Have you tested the quality though? Is it better to use this or buy a microphone? I like the concept though.</p>
<p>i watched a video where they used one of these in a guitar as opposed to having a pickup; here is the link https://youtu.be/vVQPE5c1XLA?t=5m52s skip to 8:10 to hear the quality</p>
<p>What I want to know is what do you hook the other end of the xlr cable to to make it so you can either listen or record the sound from the newly made mic? how would I do that?</p>
<p>you connect it to any xlr input on an amp or something. you could buy and adapter. or you could just wire the speaker to a standard output jack and use it with a normal instrument cable</p>
