Abstract
The present invention is a portable air horn apparatus including: a housing; an air horn assembly for generating sound, the air horn being mounted in the housing and receiving air from a small tank. An internal pump fills a small inline tank by means of a one way valve, and a release button sends the air through a diaphragm through the air horn. The air supply of the inline tank is rechargeable by means of an internal hand operated pump, in order to maintain the necessary supply of air required to produce adequate sound.
