Abstract

A horn for connection to a pressurized fluid container for sounding multiple tones has a horn body defining a sound chamber and at least one tone altering aperture extending through the horn body into the sound chamber, a sound producing mechanism located within the horn body adjacent the sound chamber, and a trigger assembly for actuating the pressurized fluid container for release of pressurized fluid to flow through the sound producing mechanism into the sound chamber to produce a sound. The horn, when the trigger mechanism is actuated, produces sound having a first tone when the tone altering aperture is unobstructed and a second tone when the aperture is obstructed.
