Intro: How to Make a Speaker.
This instructable will teach you how to make a homemade speaker.
Step 1: Gather Materials
You will need:
-enamel coated wire (you can get it from radio shack)
-a beaker or small cylinder to wrap the wire around
-plastic tub (we used an 18 1/2" x 10" x 3")
-black/red stereo wires
-magnet (the bigger the magnet the better)
Step 2: Wrap Wire
Wrap the wire around the beaker/cylinder 20x, leaving about three inches of wire on each side as shown.
Step 3: Assemble
Take the coiled wire off the beaker making sure to keep it tight.
Then, tape the coil onto the plastic tub (resonator), covering the coil and not the wires that are hanging out.
Step 4: Scrape
Scrape the enamel off of the excess wire as shown.
Step 5: Hook Em Up.
Hook up the enamel coated wire to the wires of the stereo.
Step 6: Magnet
Place the magnet under the stereo making sure to line up the coiled wire with the magnet.
