We are making DIY headphones

So, for the school project this is for, we've gotta explain why all this works. So, here's why.The 3 main components in all speakers are a voice coil, magnets, and diaphragm. The voice cool is that coil of wire from earlier. When you run electricity through a coil of wire, like this one, it becomes an electromagnet. Since it's a magnet, it's attracted to the magnet attached to the cup, and moves. This behavior can be exploited to make the voice coil vibrate against the cup, or "diaphragm." The cup acts to amplify the vibration to something you can actually hear (since, Y'know, vibrations in air are sound). In our plastic cup speaker, the diaphragm also serves as the basket, which is just another way to say it holds the flippin' thing together, though really, it's the hot glue that's doing that in my our example. Oddly enough, if we added more magnets to our speaker, it didn't become louder. Try it yourself, see what you get. Experiment! If this instructable was unclear and you don't take a speaker away from it, take the above paragraph and use that knowledge yourself to try and build one in a way you can understand. Beat us at our own game, will ya? Make a better speaker than we did, and brag about it. We'll have got you a speaker, and that's good enough for us.

Step 1: Step 1

Cut a 3 meter length of 28 gauge copper wire.

Step 2: Step 2

Wrap tape sticky side out around a gluestick.

Step 3: Step 3

Picture of Step 3

Coil the wire around the glue stick 40 times tightly, leaving about 4 inches of wire at each end

Step 4: Step 4

Affix 1 neodymium magnet to the bottom (outside) of each cup, using hot glue.

Step 5: Step 5

Take the tape and wire off of the glue stick. Cut the tape so that there is a minimum of excess tape on the ends of the coils.

Step 6: Step 6

Attach the coil of wire over the neodymium magnet. Make sure it is attached firmly.

Step 7: Step 7

Sand inch of each end of the copper wire so that the bare wire is exposed.

Step 8: Step 8

Repeat this process.

Step 9: Step 9

Picture of Step 9

Attach the ends of the wires on the speaker to the wires on the aux cable/plug/whatever.

Step 10: Step 10

Picture of Step 10

Plug the aux cable/plug/whatever into a device with a 3.5mm jack, and rock out (or something)

Step 11: Step 11

Add style. You can do this however you like.

Very cool project! How long did it take you to make?

For us, it took 3 days due to process and error. It can take up to hour.
