发明名称 Game call with two-diaphragm sounder
摘要 A hand-operated game call having a two-diaphragm sound chamber, a collapsible generally tubular bellows extending from one end of the chamber with a weight on the end of the bellows and a hollow handle on the other end of the chamber. The call is held by the handle and moved to collapse the bellows thereby forcing air through the sound chamber to produce a sound simulating the call of a wild turkey. Different turkey calls may be simulated depending upon how the bellows is collapsed.
