Video: Make a simple speaker

@ Mist8k Andy Elliott, a guy with a YouTube account, shared the wonderful "Do It Yourself" experience by self-searching to make a simple music speaker from quite popular materials in life. Of course, we can't ask for a great sound from this speaker, but somehow the feeling of creating something is really interesting right?

All that is needed for the speaker is just a magnet, a copper coil, a tape, a plastic cup and some crocodile clips (gator clips). Place the copper coil fixed on the bottom of the cup with the wire attached to the crocodile clip and then hooked to one end of the 3.5mm jack connected to an iPod. in the middle of the copper coil is the location of the magnet and . you have finished the job.

Elliott explains the principle of the speaker operation: "The current transmitted from the jack will be magnetized (magnetized) by the copper coil similar to an electromagnet. When combined with a neodymium magnet, roll The wire will cause the air to vibrate and create sound waves ".
