How to make a speaker out of household materials. This is still a work in progress and I will add more photos soon.

Supplies

These are the materials I used

28 AWG Enameled Copper Wire

10x10 mm neodymium magnet

Cheap car amplifier, or Pam8406

Soldering iron and solder

Paper

Step 1:

Cut a circle out of paper with a compass. Fold paper into cone shape. Cut small strip of paper and tape around magnet. Hot glue magnet and paper to paper cone.

Step 2:

Wrap lots of wire around paper cylinder(around 15 times),and hot glue to paper, leaving 2-3 inches on each end. Melt off the enamel from both ends of the wire

Step 3:

I just connected the ends of the speaker coil to the wires of the amplifier, but you can also solder it to a pam8403 board if you want. With the car amplifier, you get bluetooth and a screen, but if you don't need that, an amplifier board works fine
