Adding speakers to a toy
I want to add speakers to a toy but I have no idea where to start. I assume I need speakers of course but how do I figure out which is which? And if it's possible at all.
I want to add 2 speakers that will make the toy sounds more audible. I am not sure of the following though:
(a) What kind of speaker to use
(b) I assume I need to add a separate power supply for the new speakers, but how do I connect it to the toy
