The way I understand it, cars or portable speakers only have one speaker so how do they play many different sounds at the same time?
In: Technology
When there are many sounds, they overlap and create a complex wave. (Even individual instruments/voices are usually complex, but even if you’re just using basic sine waves.)
You can’t hear the difference, because there really isn’t any, between all the separate sounds blending into the complex wave, and just playing the complex wave to begin with. So that’s what the speaker does.
