How are headphones with single drivers able to make sounds that are “multiple sounds at the same time?´´

Question

So from what I know, the drivers vibrate at a given wavelength and that makes a sound. That makes sense to me of how you can create voice for example. But how does multiple instruments + voice in one driver work? You hear all them seperately but at the same time?

To me this sounds like a monitor pixel making more than 1 pixel at once.

Answer 1

The reverse question is: how are your ears able to perceive more than one sound at the time? It is also a singular diaphragm, the ear drum, vibrating, but yet somehow it accomplishes the feat. Answer: it is fundamental property of sound that they can be summed together and both generated and perceived at once.
