How do speakers produce multiple sounds at the same time.

Question

I have never really fully understood how a speaker vibrating air molecules which then in turn vibrate the membrane in your ear works. How can a speaker make multiple sounds at the exact same time if its based on movement of a physical object?

If you’re interested, how do people know how to “add sounds”, there’s a special idea in maths for handling that (and much more, like multiplying polynomials!). It’s called “Fourier Transformation” and it’s really interesting!
