Step 1: Step 1:ASSEMBLING , SANDING

To begin the process of making our headphones, we must create 2 voice coils. A voice coil, is a coil of copper wire generally between 50-60 coils made of the 28 American Wire Gauge with 11 cm left on both ends of the coil. Coil it on a highlighter. I used 50-60 coils because I found that the lyrics were clearer in the music when you use between 50 and 60 coils.

You have to coil the gauge wire so that when it becomes a temporary magnet and goes around the permanent magnet, the current is flowing counter clockwise, that’s what causes it and the permanent magnet to attract and repel each other, When this happens the voice coil vibrates and sound is created. That is why you must coil the voice coil.

Slip the voice coil off of the highlighter. Make sure to hold it together to prevent it from uncoiling. Use the extra 4 cm on the ends and loop it around the coil to prevent it from springing up and uncoiling.

Tape it so it won't uncoil. Your voice coil should look like this.

Sand about 5 cm on the ends of the voice coil, so that it may connect and be soldered to the aux cord and the terminals.

REPEAT THE VOICE COIL PROCESS TWICE

Step 2: MAGNET POSITIONING & DIAPHRAGM ASSEMBLY

Next take the base/diaphragm of your headphones, or what you want to have on your ears, in this tutorial, I used two plastic cups, one for each ear.

I chose 6 magnets because they made the audio louder which was what I needed.

Use 3 neodymium magnets per cup, put two on the bottom inside of the cup and

Center the magnets in the center of the surface because that way when you put the voice coil you made around the magnet it will attract and repel each other because the force is going in all directions.
Put the voice coil you made around the magnet.

Puncture two holes next to the magnet. Make them across from each other.

Put the ends of the voice coil into the holes. Pull the wires from the outside so the the voice coil is tight against the inside bottom of the cup.

Use tape and secure the voice coil to the bottom of the inside of the cup and magnet to prevent it from detaching. .

Connect the ends of the copper wires to the aux cords, put one end in the hole of the aux cord and wrap it around the terminal.

Put the other end through the hole but wrap it around the wire

Step 3: PLUG & PLAY

The moment you’ve all been waiting for! Plugin your aux cord into your audio device and play any audio of your choice!

And magic (actually physics)! There are your DIY headphones!

Step 4: Troubleshooting

ISSUE 1

Sound isn’t playing at all, what should I do?

It is possible that your wires are touching causing disruptions/no sounds playing, make sure they aren’t touching.

ISSUE 2

I can hear the music but not the lyrics.

Make sure that the voice coil is surrounding the magnet and not on top of the magnet. The reason why the coil shouldn’t be on top of the magnet is because it won’t vibrate and no sound will be made. However, if you put it around the magnet, it will attract and repel the magnet causing vibrations, and furthermore causing sound!

ISSUE 3

There’s a static noise.

Solutions Plug in your aux cord correctly Straighten out your wires/ make sure that they aren’t crunched up.
