发明名称 Diaphragm-type game caller
摘要 A game caller has a size and a wafer-like shape for support against the roof of a user's mouth and includes two diaphragms that are supported in spaced apart relation by a frame in one embodiment and two frames in a different embodiment. A further embodiment provides that a frame is divided into portions for holding and spacing the diaphragms. Each diaphragm is tensioned and held to present an exposed edge portion which is caused to vibrate by impingement with exhausted pulmonary air from the user. A casing engages the exposed parts of the frame and extends outwardly therefrom to hold the assembly together as a unit.
