This is a speaker i made from scratch useing scraps i found around my home. The goal of this project was to make a speaker for free out of scrap. The other thing was that i did not use a pre made speaker to make this.
I will show how to make it, so you can build your own :)
Heres a video of the sound of my speaker.
Step 1: Parts and Tools
card board tube
coated copper magnet wire (This must be atleast 8 ohms to protect your devices)
Step 2: Make the Speaker
Make a copper wire coil a little bit bigger than the diameter of your magnet.
Place the wire in the center of the bottom of the cup.
Step 3: Make the Speaker 2
Now build a bracket to hold the magnet. The magnet must be placed in the center of the wire coil.
To make the bracket make the paper clip straight. Then tale it io a peice of card board. Then flip it over and tape the magnet on the back side of the bracket.
Make shure you tape secureley because this part must resist the vibrations from the magnetisim when the speaker is on.
Step 4: Make the Speaker 3
Now tape the bracket to the bottom of the cup. Make shure the magnet is placed in the center of the coil.
Also make shure to secureley tape this on.
You now have a bare speaker with no way to connect to the music player.
Step 5: Make a Case
Now you have a ugly cup with card board on it. Now make it look a little better by adding a case! Because this is supposed to be a paper speaker i made the case out of cardboard and paper.
First make a front plate out of card board.
Trace the diameter of the top of the cup on to a peice of cardboard and then cut it out.
Step 6: Make a Case 2
Now make a support to make the cup level.
Made out of a card board tube and taped to the cup.
Step 7: Make a Case 3
Make a bottom panel.
Make shure you leave some room in the back for the wires.
Step 8: Make a Case 4
Now make a back pannel. Tape it so it will open like a door. Also cut a hole so the audio jack wires can come out.
Step 9: Solder Time
Solder the 2 coil wires to the audio jack wires. It does not matter which way they are connected.
Step 10: Make a Cover
Now cover the card board with paper so it would look nice.
Step 11: Enjoy Your Speaker
The speaker may require some fine tuneing of the coil to get some sound out of it. The volume of it will come from the streingth of the magnet and the coil.
The speaker quality is pretty good considering that its made of paper and hand made.
If all works well, Enjoy your speakers!!!
