When you push on air, it moves and pushes on the air in
front of it but with some delay in the transfer. That's
what causes the speed of sound. The push propegates outward
from this bit of air to the bit in front of it and that's a
wave. Same when you pull on it.

Does that help?

Sorta. From what you're saying. the *origin* of each individual wave can
take place at any point within the throw of the diaphragm. Is that correct?
