How do headphones work? (As in how does electricity get turned into sound)
In: Technology
I have a decent understanding of the principles of how speakers work, but the fact that they work as well as they do is still magical to me.
And it’s way more magical when you consider early recording, where it’s basically and anti-speaker (microphone) turning sound into electricity, which then gets written to a wax plate, which can then be mass reproduced using inexpensive vinyl blanks, which can then be played back at nearly the same fidelity as the original sound using a relatively inexpensive machine.
