How can a single speaker cone vibrating reproduce the sound of all the individual instruments of an entire orchestra at once?

I imagine the cellos causing the speaker to vibrate, then I imagine adding in the violins, and then the percussion, and then the woodwind etc. and how their vibrations would all interact with each other. How can this all be reproduced accurately on one speaker cone?

Riding a sine wave on a sine wave. 

Say you had a high freq sound wave going steady, and then you played a low wave at the same time. You would actually be able to observe that as the low wave caused the cone to move back and forth slowly, it would at the same time be vibrating quickly along the low freq wave.

Move your hand up and down. Hold it still and shake it. Now shake it while moving it up and down. High freqs and low freqs work together like that.
