Hi.
Am looking for a small speaker, less than 40mm diameter, with a built-in class C or D amplifier powered by lithium cell voltage.

Cell phones/tablets can be loud! in hands-free mode; run on 4V, would work. Knowles makes one with integral amplifier but for earphone use. Do you know of any manufacturer that may have such ?

There are a lot of gadgets, toys and novelties that you can plug into a phone and have a small powered speaker built in. If you just need one piece for a quick project, I'd probably just hack one of those.
