Can you amplify and power a telephone keypad?

I have an old telephone keypad that I want to amplify, but I believe it needs a power source to do so? I've already used the telephone to make a microphone. I'm not looking for suggestions regarding making "songs" with the keypad, I can do that. I want to know how to amplify the keypad sounds.

It's a tone-dialler? I guess you just need an amplifier?
