A Beautiful Speaker

Speakers work through electromagnetism, where a current flowing through a copper wire produces an electrical field that interacts with a true magnet, causing the wire to vibrate and produce sound. I'm gonna teach you how to make one through SCIENCE!

Gather the following

- Magnet Wire

- Powerful (Neodymium) magnet

- Audio jack

- Paper plates

OPTIONAL

- Amplifier and Power Source

You will want to wrap some printer paper around the magnet to serve as a base for the coil (as shown). You do not want it to be too tightly wrapped, so give it a little bit of breathing room.

Begin wrapping your magnet wire tightly around one end of your cylindrical paper. Do so for about 50 turns, but more does not hurt. Make sure to do the loops fairly tight around the cylinder, and keep them close together unlike what it shown in the image.

Hot glue (or tape) the cylinder directly to the bottom of one paper plate. This will serve as a the actual vibrating piece of the speaker. Putting some glue onto the coil to keep it in place is not a bad idea.

Place whatever container you desire to use as the home for your speaker onto the paper plate and draw a circle that lines up with the lip of the container. Here I am using a coffee can painted with blue and white stripes, but yours can be any shape or size.

Now cut out aforementioned circle so that your speaker will fit properly on it's container. Be sure to leave a little bit of overlap so that you can adjust the placement as needed.

Attach your audio jack to the magnet wire coil, with the following configuration:

-Ground and Right on one wire

-Left on the other wire

Be sure to use a lighter to burn off the enamel either while it is connected to the audio jack or before. This will enable the current to flow.

Wire your speaker directly into an amplifier so that you can control the level of sound and it's quality. Explaining how to complete this step in depth would require a whole new Instructable, so use one of the many guides out there.

Place fully wired coil plate on top of the magnet, and hook it up to a laptop/phone to test. The plate should vibrate and produce a sound. If not, check your wire and placement of magnet inside of the paper cylinder.

Place now functioning speaker into any container that suits your fancy. I chose a box container for mine.
