ABSTRACT:
A game caller is shown including a diaphragm assembly that is vibrated in opposite directions by rapid bursts of air from a bellows. The only opening in the bellows is tubular and it is attached to one end of an elongated tubular housing where an end cap holds the diaphragm assembly onto the housing. The free end of the tubular housing permanently carries a cone-shaped megaphone forming a sound amplifier. A tubular cloth case has one end secured to the outer surface of the housing and the other end has a sewed pocket containing a drawstring. The case is utilized as a container for the bellows in a collapsed state for transporting the game caller. To prevent inadvertant operation, the closed end of the bellows may have an exhaust opening that is to be blocked during operation of the caller.
