HOW TO MAKE A SPEAKER IN HINDI :
1
Find copper wire, packing tape, and a strong magnet. While there is a lot of calibrating that goes into high end speakers, the basic technology is actually pretty simple. An electrical current is run through a wire that is attached to a magnet. This current makes the magnet vibrate, and those vibrations are picked up by our ears as sound.[1]
To hear the sound well you should also get a small plastic tupperware or cup. This will amplify the sound much like yelling into a cone amplifies your voice.
