There are many ways to make a speaker for almost any device and almost any materials at hand. We will not describe everything, especially since one article is not enough for this. We will restrict ourselves to two rather simple ways.
Instructions
Step 1
First, choose a nail, think about the approximate height of the speaker. Cut the nail so that it is slightly less than the projected speaker height. Grind the cut side of the nail with a sharpening stone or file. When the surface is smooth and free of burrs, wrap insulated copper wire around this part of the nail with a head. But before that, you need to do the following: take two paper clips, break them with a hammer on the anvil until they are as thin as foil. One of these clips will be the base. Now take a nail and glue it to the base paper clip.
Step 2
Now take a magnetic tube that is slightly taller than the coil nail. This nail must go into it. Glue this tube to the base and cover it with a lid from another button-clip and glue it. Such a speaker will work decently, without squeaks, groans and extraneous sounds.
Step 3
Here's a way to make speakers out of coffee cups and old headphones. These speakers are perfect for use with an MP3 player.
Step 4
Take a cardboard cup, old headphones, and duct tape. Mark the center at the bottom of the back of the cup and make a hole in it. Place the earphone over the hole and trace around it with a pencil. We need to make a slightly smaller hole.
Step 5
Now insert the earphone into this hole and glue it with tape or any other adhesive tape. Look inside and check that there are no foreign pieces of cardboard and that the earphone is in good contact with the bottom. Otherwise, your sound will rattle. That's all, the speaker is ready. Do the same for the second speaker. Although the speakers are comic in appearance, at full volume they are capable of producing sound with a force of up to 10-15 decibels.
