Abstract
An air horn and method of using such a horn is rechargeable by a conventional air pump for use when the air, acting as a propellant, is depleted from its container connected to the horn. The device may be connected to a bicycle or may be used, for example, on a boat. The device is sounded by depressing an activator or an actuator which releases air into a membrane of the horn to vibrate a diaphragm. When air is depleted from the container, an adapter having an inlet valve connected thereto permits connection of a conventional pump or a built-in pump for refilling.
