ELI5: How is sound recorded?

I do have somewhat of an understanding of how the ear perceives sound, and how speakers work. But I am just lost on understanding how something can record the exact sound it receives. Please help..

Sound is just waves in the air. Inside a microphone is a membrane that vibrates back and forth with the waves. Attached to this membrane is a coil of wires, this coil of wires moves back and forth across a magnet as it moves back and for with the membrane (and therefore, with the waves.) The coil of wire moving back and forth across the magnet generates an electric current in the wire, precisely the same pattern as the pattern of waves.


Does that help? Any questions?
