How To Make a Speaker

A homemade speaker using a plastic cup, business card, wire, magnet and some Lego blocks. I built this speaker from scratch; I was surprised of the quality of the sound. Updated!

It doesn't look like a high-tech speaker but it works well. I didn't expect a high quality of the sound from this made-from-scratch speaker but it performs very well, better than I expected.

A speaker is just a magnet, a coil, frame and a cone or any material that can make the air vibrate. Here is the bill of materials that I used to build this speaker:

1 Magnet (neodymium magnet works great)

1 Business card

Wire 32 or 34 AWG (you may use 30AWG)

Paper bond

Tape

Glue

Scissors

Ballpoint pen

Lego bricks or wood.

Ruler.
