I am designing a fairly small (25 x 25 x 25 mm) robot, and I want to
have some sound output. A simple click or buzz or beep will do quite nicely.
The smallest device I've been able to find is a cell phone speaker that's
8x8x4 mm in size. Anyone know of something smaller that's actually
available? Thanks!

I think cellphone speaker can fit very well in you robot. You can make
small power amplifier and place 4-5 pieces speakers surrounding your
robot. The simplest is just put a loud beeper, very loud indeed.

You can take a piece of bimorph piezo material and make it 1 X 1x .001 mm if you want.
It would need driven by a signal, and the smaller it is the less LF energy
its going to have.
