Question

How speakers can make so many different sounds at once when they only have one membrane

In: Physics

Answer 1

Imagine the diaphragm of the speaker and how it moves long distance to make a bass sound. Now it moves much smaller distance to make a high pitched sound. What happens is as the diaphragm is moving long distance to make the bass sound it is simultaneously moving the small distance to make the high pitched sound.  It’s just not doing this movement around the resting location but vibrates back and forth around the current location of the bass sound travel point.

You can imagine the diaphragm moving in a two step forward one step back kind of thing.
