How to make a speaker out of a plastic cup, lego, wire and a magnet
Hack together a speaker out of stuff you have laying around. It’s crude but it works and it is an interesting little experiment/project.
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:
# List of materials 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.
