In this instructable, I will be introducing DIY headphones. The purpose of this DIY is to apply physics knowledge into a real world DIY. For instance, headphones are a perfect example of sound waves. Sound Waves have many components, period, frequency, hertz.

Step 1: STEP 1: Gather Materials

Materials:

  • 28 AWG copper wire
  • 2 neodymium magnets
  • Sand paper
  • Aux cord/ plug
  • Alligator clips (optional)
  • Plastic cups (2)
  • Phone
  • Gluestick
  • Tape
  • Sticky Notes
  • Electrical tape

Step 2: Step 2: Wrapping Coils!

The items you will need to complete this task will be the copper wire, glue stick, and tape.

  • Grab around 3 feet of copper wire
  • grab your glue stick and apply tape around keeping the adhesive side up
  • Leave around 2 inches off so you can be able sand in the later steps
  • wrap the coil on the adhesive side, then wrap as many times, but don't go over 50!
  • Once that process is finished you should be able to slide off the tape with the coils wrapped.

Step 3: STEP 3: Sanding

For this step you will need your wrapped coils and sand paper.

  • Before you start sanding, make sure you have at least 2 inches sticking out
  • Grab your sand paper and start sanding the edges
  • Keep sanding until all the red color strips are off and only copper is revealed

Step 4: Step 4: Assembling the Speaker Part 1

For this portion, you will need: One plastic up, 2 neodymium magnets, voice coil, and electrical tape.

  • Grab the plastic cup
  • With a ton of force, pull apart the two magnets
  • Place one magnet on the inside and the other on the bottom of the cup
  • With the cups bottom part facing up, place the voice coil on top so it's around the magnet
  • Use 2 strips of electrical tape to secure
  • Make sure that each ends of the coil are sticking up and out
  • cross tape to be more secure.

Step 5: Step 4: Assembling the Speaker Pt 2

For this step we will continue on using the cup with all the components on it, but we are adding the aux plug.

  • With the cup & voice coil attached on it, grab the ends that are sanded
  • Grab your aux plug
  • Grab one end and insert into one of the holes in the aux plug
  • repeat the same thing for the end

Step 6: Step 6: Groovy Tune Time

Your speaker should be all set by now: you will need the completed speaker and an audio source.

  • Grab the aux plug in and insert it into your phone
  • play some groovy tunes
  • you may have to move your phone to hear something
