how do car horns work, anyway
@Felthry It seems to be an electrical buzzer sort of thing, like a loudspeaker with a diaphragm and such, but can really only make the one sound.
@VoxSomniator Huh, really? I would have thought it'd be cheaper to have an air horn
@Felthry Big trucks use compressed air horns! They already have compressors for the airbrakes, so I guess it *is* cheaper there.
like, is it compressed air? I'm quite sure it's not a conventional loudspeaker
