ELI5: When we increase the volume, does the speaker produce more sound waves or it's the same amount and they only get longer/shorter?

If you look at a graph of the wave, it would be taller, but the shape stays the same\*. The horizontal length is how long the sound lasts. 

\*: Only if your amp and speaker are perfect. In reality, the shape can change a little as you turn up; this is called distortion.
