Everyone once taught that speakers were confusing and complicated. But did you know that you can make your very own speaker at home out of household items. Today I am going to show you how to make a paper plate speaker for cheap.
Step 1: Tools and Parts
The tools and parts you need are:
Two paper plates
Pencil or pen
Step 2: Cutting Paper
Start by marking the magnet 1/5 of an inch from the bottom of the paper and using a ruler make a line and cut the strip out. Now tape the strip of paper to the magnet and roll the strip on the magnet. Mark another line exactly the size of the magnet. Roll the second strip of paper onto the magnet and tape it.
Step 3: Voice Coil
The voice coil is the most important part in a speaker. I made mine using magnet wire that I salvaged from a motor. Start by taping the magnet wire to the paper roll and start wrapping the wire on to the magnet. When you are done wrapping the wire on to the magnet, tape the coil for it to not move around. Remove the second roll of paper with the coil and remove the first roll of paper that was taped to the magnet. Now your done with your voice coil.
Step 4: Assembling the Speaker
Now mark the centers or your plates by drawing a X on the plate. Then Hot Glue the coil and magnet in the centers of the plates.
Step 5: Suspensions for the Speaker
Take your business card and cut it in half. Fold both in half. Then hold each side in half again. Hot Glue the suspensions evenly on both sides on both plates. See pictures for more detail.
Step 6: Finishing and Testing
The last step is to burn or sand the protective coating off the wires and hook it up to your amp. Have fun and jam to your favorite song on your new paper speaker. Your family and friends will be amazed at what you built and you can explain how it works
