Add an audio input to a megaphone

This instructable shows how to add an audio input to your megaphone. It's super easy and make your megaphone way more useful.

Why add an audio input?
Megaphones are good for getting noisy at protests. And there's no shortage of reasons to get with your friends and organize a protest: a growing economic crisis, systematic exploitation of animals and the earth, climbing unemployment, massive student debt, wars and occupations, and so on. Megaphones are great, but you're limited to amplifying only what you can put into a microphone. What about music? Ms Emma Goldman said something like, "if I can't dance, I don't want a part of your revolution."

So with a few minutes of work you can add a new dimension to your protests and critical mass bike rides. You can blast music.

What you'll need:
+ a megaphone (got mine for $10 at harbor frieght)
+ an old pair of earphones (old broken pair)
+ soldering iron and solder
+ electrical tape
+ scissors or knife

Short version:
In this project you'll snip your megaphone's mic wires, snip your earphones, and then solder your earphone jack onto the mic wires.

Step 1 Open up your Megaphone

We're going to patch a second wire onto the microphone input, so you're going to need to get into the part of your megaphone where the microphone connects. On my megaphone, I had to take out two screws on the panel above the batteries. Inside you'll find two wires coming from the microphone, usually one red and one black.

hey drewsaysgoveg,

hahahaha this is such an awesome project to annoy people with your singing XD. Have you had any problems so far? I'm planning on doing this for a X'mas present for my mum (whos tone deaf) that loves singing XD.

the only problem was that I ripped out the cord once. I was biking around with it and I dropped my mp3 player. The force of it pulled out the audio cord. I just had to re-attach it the same way. Worked fine.
