Abstract:
1. A game call apparatus, comprising: a housing; a sounding board coupled to the housing, the sounding board defining a main air channel; a reed coupled to the sounding board adjacent the main air channel to produce sounds when air passes through the main air channel; a pressure point structure disposed in the housing, the pressure point structure engaging the reed at a reed contact location, the pressure point structure urging the reed toward the sounding board at the reed contact location, the pressure point structure being movable relative to the reed, as air is forced across the reed to change a free end length of said reed which is free for sound producing vibrations; and a rigid cylindrical member configured with a spiraled groove portion therein, so that rotation of said rigid cylindrical member results in relative longitudinal movement with respect to said housing, which longitudinal movement simultaneously allows for some variability of said free end length and limits a range of variability of said free end length.
