Hi All-

My friend has a voice changer toy with a pretty weak speaker, and he's looking to boost the volume. Is there a way to do this electronically through more power or changing resistance, or would the best bet be to install a larger speaker? And, if I do install a larger speaker, how do I know how much power to use for both the board and the speaker? Sorry for the question, but this is my first foray into audio and electronics. Many thanks to all!

This may be what you need:

The way you have it in your schematic isn't the same as how you have it wired up!

The LM386 chip is designed for this, its very easy to use requiring only a few easy to find components -
