ELI5: How do speakers work? My brain just can't comprehend how all the sounds and frequencies at one single point in a song (drums, vocals, guitar, etc) can be created by one single vibration of a membrane. All at once!?

I really need an explain like I'm 5 here..

All sounds are waves in a material. The wave is formed by compressing and expanding the material at some rate. If 2 things try to expand and compress the same piece of material then they will interfere.

&nbsp;

Imagine someone is pushing and pulling on you. You will shake around. If a second person pushes and pulls on you then you will only shake in 1 pattern that is the result of both people pushing and pulling on you. So interference of sound waves results in a new sound wave. So if you record all the pieces of a band and all their sound waves, you can combine them into 1 new sound wave that when played back sounds like all the instruments playing together.
