Speakers exploit the interaction of magnetic fields to create sound waves. This video explains the process and describes how to construct a simple speaker.
Sometimes it appears so incredible to me that how some very simple ideas/techniques work in real world so easily (in this case just a plastic cup, a permanent magnet and a copper coil - things that are quite 'primitive' - would create the desired output). Refining the implementation details would of course make it the "cutting edge", but underneath it is so simple!
You sir are simply unbelievable! you have taught me what my highly qualified teachers couldn't! by the way if you care to reply what music were you playing at 3:25! name please!
If I had a GOOD inspiring teacher like you in my childhood my things today could be a way better
