Hi all!
In this tutorial, I'll be showing you how to make a high definition speaker for only a few dollars.
For this you will need:
- Paper Plate
- Aluminum Foil
- A Shiny Penny
- An unwanted CD or DVD
- A Head Phone Jack With Exposed Wire

Ok, so first off get your paper plate and place the DVD or CD in the middle then tape it.
Next take hold of your aluminum foil and wrap up your paper plate around the convex side. Make sure there are no gaps for air to escape.
By now, you should be left with something like this:

After you've done this, place your shiny penny on the centre of the foil (it is important that your penny is shiny as it will result in little or no sound from your speaker). Now use your tape to hold the penny in place.
This is the tricky part. Get your headphone jack with exposed wire and place both wires on top of the penny. Then, hold the wires and the penny down with some tape. Be careful not to tear the foil in this process.

Now you're ready! To test it out, plug the jack into your PC, stereo or mp3 player etc and listen to the great sounds.
Thanks for reading
