1_Wizard
I don't. I know the sound is either acoustic, using hollow wood or plastic, or electric amplifier and and a speaker.

So can you explain the difference beweeen the types 
1_Wizard
Well, the modern acoustic has three types, classical guitar which is nylon string, the steel string acoustic and the archtop guitar.

How about the .other types?

The tone for an acoustic guitar is made by the vibration of the strings, and the hollow body amplifies it, and that acts as a resonating chamber.
