Abstract
A game call having a mouthpiece with an internal latex diaphragm and secured to said mouthpiece is a diaphragm plunger which is operable by pressing an artificial tongue-like pliable section into contacting with the diaphragm, thereby changing the pitch of the sound produced.
Claims27
A game call comprising:
- a mouthpiece body having an air inlet end and an air outlet end and an air flow axis along the mouthpiece body between the air inlet end and the air outlet end;
- a diaphragm disposed within the mouthpiece body between the air inlet end and the air outlet end and adapted to vibrate and generate sound when air is blown into the inlet end;
- a pliable segment extending parallel with the air flow axis and spaced from and opposing the diaphragm so that manipulation of the pliable segment causes the pliable segment to contact the diaphragm to change the sound;
- and
- an opening in a central portion of the mouthpiece body, the opening exposing a portion of the pliable segment to provide access to the pliable segment for manipulation of the pliable segment.

A game call comprising:
- a tube having a mouthpiece end and an air outlet end and an air flow axis along the tube between the mouthpiece end and the air outlet end;
- a diaphragm unit comprising a U-shaped frame and a diaphragm spanning across the frame, the diaphragm unit being detachably mounted within the tube between the mouthpiece end and the air outlet end and adapted to vibrate and generate sound when air is blown into the mouthpiece end;
- a pliable segment extending parallel with the air flow axis and spaced from and opposing the diaphragm so that manipulation of the pliable segment causes the pliable segment to contact the diaphragm;
- an opening in a central portion of the tube, the pliable segment disposed within the opening thereby providing access to the pliable segment to allow for manipulation of the pliable segment;
- and
- a sound chamber structure disposed on a side of the diaphragm opposite the pliable segment.

A game call comprising:
- a tube having a mouthpiece end and an air outlet end and an air flow axis along a length of the tube;
- a diaphragm unit comprising a U-shaped frame and a diaphragm spanning across the frame, the diaphragm unit being detachably mounted within the tube between the mouthpiece end and the air outlet end and adapted to vibrate and generate sound when air is blown into the mouthpiece end;
- a pliable segment extending parallel with the air flow axis and spaced from and opposing the diaphragm so that manipulation of the pliable segment causes the pliable segment to contact the diaphragm;
- an opening in a central portion of the tube, the opening exposing a portion of the pliable segment;
- a sound chamber structure disposed on a side of the diaphragm opposite the pliable segment;
- and
- a plunger adapted to depress the portion of the pliable segment into the opening when the plunger is manipulated by a human digit.
