Never seen one so I can't say for sure, but it's doubtful you'd have much luck trying to hack it. My best guess is that it's a high frequency oscillator driving a piezo element. Even if it does have a conventional amplifier circuit in it, the piezo wouldn't reproduce the frequencies you'd want it to.

It might have some use as a triggered audio player. Looks like a large built in speaker. I'll bet with slight modification you could wire an audio plug to have it play the audio off a cheap player whenever someone approaches. The price is about what HD charges for a light sensor.
Regardless of the hack...I could use one of these to shoo off skeeters when I'm prop building outside in the evenings. 5,000 sq ft range?....hmmm.
