Well, he asked about the old-fashioned electromagnetic gong, which has a contact on the armature that opens the circuit every time the clapper strikes the gong, so it should work equally well on AC or DC.
I once wired a normally-closed relay contact in series with its coil, just to see if it would work, and it functioned as a buzzer just fine.
