Let's walk and talk, there's a place nearby I work at that sells some great food that I think you'll like.

Soundwaves, right? Sound isn't just a thing like that on its own, it's a kind of energy that moves in waves; that's why it vibrates stuff once it's loud or deep enough.
Because it's an energy, you can convert it into other kinds of energy, too. Like heat, or electricity.

That's how more advanced audio tech works. You've got little wires that can carry electricity and something that can convert the vibrations from sound into electricity to send through the wires.
Like a needle in a gramophone, but instead of going to a diaphragm to send out a horn, it goes into a wire to send somewhere else.

You following so far?

[This must sound great to listen to, considering she's always singing.]
