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

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.

imagine the air being the surface of a pond. toss one pebble into the pond, you get a single wave radiating from the source. if you are standing in the pond the wave will hit your leg at some point. or a leaf floating in the pond would move up and down with the wave, same as how your ear drum moves when a sound pressure wave gets to it.

now toss two rocks in, one after another, the second one landing in a different spot. what you see now on the water is a pair of waves, with them crashing into each other and interfering. when the waves are both up at the same time, the water is higher at that point. same when they’re both lower. when on wave is up and the other slightly down, the water will be somewhere in between. your leaf will move with the wave combination just like your ears will hear the sound combination.

a speaker can play back multiple waves stacked on top of each other, just like the leaf movement is two or more waves pushing it up and down.
