The novelty radios have the same type speaker and the poor tone proves it.
BTW, can you post the schematic. It seems interesting. Schematics are the universal language.
Sure, can take a shot of it later tonight. It's really nothing amazing though, in concept it is strikingly similar to the Westinghouse 99A I just got yesterday (although implementation is slightly different!

The fun for me was getting my 9 year old daughter to help.. she had fun with the colour codes and reading all the tiny numbers on the components.

That speaker may be swapped out.. I have a too far gone USSR built portable radio with a similar size speaker, and I think it will provide far better tone.

There is a video on youtube where someone makes a sticky-note into a speaker by placing foil coils 'wound' in opposite directions on opposite sides of the paper connected in series by punching a hole through the center. It sounded bad IIRC, but it did work.
