How to make headphones
2 500ml-plastic bottles
2 1-liter milk cartons
The type with plastic film that covers up to the top.
Do not use the bottleswith this kind of half shrink label.
2 Magnets with spacer
Diameter of 20 mm or less
4 aluminum foil tape strips
2 20-meter copper wire rolls
(diameter of 0.2 mm)
4 sleeve joints
※Double-sided tape (If necessary)
Headband made from milk cartons
You can make one-of-a-kind original headphones by decorating them with materials such as yarn.
Headphones made from plastic bottles
By wrapping them with copper wire in a coil, they will vibrate and produce sound.
Decide where you want to cut the bottle by placing a rubber band around it, and then draw a line with a pen and cut the plastic bottle with scissors or plastic bottle scissors (do this for both bottles).
plastic bottle body
Draw a line with a pen
* It will be easier to cut if you draw the line in advance.
Line denoting the finished headphone shape
Remove the film (from both bottles).
Cut the plastic bottles along the line for the actual headphone shape.
Once you cut the plastic bottles and remove the film, smooth the edges by cutting them in straight lines (both bottles).
* If the edge is rough, the film may rip later or the edge may cause injury.
Replace the film on the plastic bottle (both bottles).
Shrink the film with the heater (or a hair dryer) (both bottles).
* Wear a glove so you do not burn yourself.
* If you cannot do it yourself, please ask an adult to do it for you.
Double stick tape
Wrap the copper wire around the plastic bottle (both bottles).
Apply a piece of double-sided tape on the neck of the plastic bottle so that the copper wire will not slip.
Leave the first 10cm of the copper wire and start wrapping.
It will be easy to wrap the copper wire if one person holds the bobbin with a screwdriver through the hole of the bobbin while the other person wraps the wire around the neck of the bottle.
Secure the copper wire using a piece of vinyl tape or a sticker.
Once you finish wrapping the wire, leave the last 10 cm of wire while securing the wire with a piece of tape or a sticker (both bottles).
Roughen 3 cm on the ends of the copper wire (the first and last part of wire) with sandpaper.
First, run the copper wire through the sleeve joint.
Twist together the rough part of the copper wire and the tip of the audio cable.
Roughened copper wire
Wrap the aluminum foil tape strip around the twisted part.
Aluminum foil tape strip
Pull the twisted section into the sleeve joint.
Tightly crimp the sleeve joint using the crimping pliers.
* If you cannot do it, ask an adult for help.
When you finish one side, connect the audio cable to the other side as well.
Did you make it?
You can hear the sound soon!
Attach the magnet to the plasticbottle cap.
* The shape and size of the cap will differ depending on the type of plastic bottle.
* Attach the magnets so that the same magnetic poles are facing each other from the left and right sides.
* The magnets provided in the kit have stickers on the same magnetic poles so that they are easy to identify.
Handle the magnets with care because they are extremely powerful!
Apply the stencil sticker onto the milk carton.
* Use the folding lines on the milk carton.
Using scissors, cut along the lines on the sticker.
* Solid lines indicate a cut and dotted lines indicate a fold.
Once the carton is cut properly, you can take the stickers off.
Fold in half and secure with a stapler and/or double stick tape.
Headphone holder section
* When using a stapler, pay attention to the direction of the staples.
Now, create an adjustment band using the second milk carton.
Match the size to your own head and attach the headphone holders to the headband.
Carefully bend the adjustment band so that it fits the shape of your head.
Adjust the headband to match the position of your ears and secure the headphones to the headphone holders by attaching the cap.
Decorate your personal headphones by wrapping the headband with yarn and ribbons, and attaching beads.
Your original headphones are now complete!
