Abstract: A simplified combination animal call has a casing divided into identical upper and lower half sections held together by a securing elastic band. Symmetrical channels of different widths spaced longitudinally along half sections provide airways through the casing whose openings act interchangeably as mouthpiece openings along one side of the casing and sound-emitting bells on the opposite side. Air blown through any such airway vibrates a second elastic band which spans each airway to produce an animal-like sound. Multiple airways of different widths make available several different pitch ranges at once. Changing either the size or tension of the vibratory elastic band changes the pitch that is available at each slot. Finally, the pitch produced may be dynamically varied either by changing the tension on the vibratory elastic or by compressing the mouthpiece side of the casing while the device is in use.

Abstract: A combination deer-predator call has a casing divided into upper and lower half sections held together by end caps. A pair of hinged flaps at opposite sides of the upper section form movable mouthpiece portions which define with adjacent lower casing portions mouthpiece openings which lead into an interior air space of the casing. Air blown through either opening passes across one of two elastic bands each stretched between an end portion of the casing and a corresponding slide positioner to produce an animal-like sound. The pitch of the sound produced by each band is varied by moving the associated slide positioner along a positioning slot in the casing to different retention slots. Each flap, when pressed inwardly, clamps its associated band in one of several variable stretched positions as determined by its slide positioner to produce a clear sound of the selected pitch. When released, the flaps enable the tension in the operative portions of the bands to be changed by the slide positioner.
