I would use a speaker that fits that size pipe, then an audio source. That would be most flexible depending on your need for the frequency of the sound. Kind of like the Bose Wave radio.

Thinking of a starter pistol. Banging on the side of the pipe is not good enough. Need a loud pop that I can do over and over. Whatever makes the noise need to be small. Not sure if there is a small loudspeaker that could produce an impulse sharp and loud enough. Do they still make cap pistols? Not sure if toy caps would be loud enough or not.
