Physics seems to tell me that pressure will be proportional to force,
and force is what accelerates the diaphgram. Therefore, shouldn't
the pressure and the diaphgram's instantaneous acceleration be
proportional? If so, then the diaphragm's velocity is the
integral of the pressure over time.

You seem to be ignoring the restoring force, since the diaphragm is
restrained
and not free to move in response to the pressure exerted.

Hmm, I am starting to learn that all this stuff is way more complicated
than I thought it was. Thought I understood it, but apparently only in
a very shallow sense.

How big is the restoring force compared to the force due to pressure?
I'm assuming significantly smaller, so that ignoring it can still give
you a workable first-order approximation. Or is that not true?

It is the sum of all forces resisting the movement of the diaphragm: it would
depend on the tension applied to the diaphragm in the case of a condensor
element and the stiffness of the suspension for a dynamic element. In the case
of the condensor element, displacement is very small whereas with a dynamic
element, there is more significant movement. This would imply that the
restoring force is large for a condensor element and smaller for a dynamic
transducer.
