Abstract
An adjustable tone game call apparatus has a housing with an internal air passage through which air may be blown. A reed is positioned in the housing along the passage and is configured to vibrate and generate sound upon passage of air through the air passage. An adjustment member on the housing rotates or translates to vary pressure applied to the reed, thereby adjusting the tone or pitch produced by the reed due to the pressure changing the effective length of a diaphragm of the reed. Thus, by using the adjustable tone game call, a hunter may produce a variety of pitches and tones to mimic various types of game animals and predators.
Claims20
An adjustable tone game call apparatus, comprising:
- a housing having an internal air passage, the internal air passage having an entrance opening and an exit opening;
- a reed positioned in the internal air passage between the entrance opening and the exit opening, the reed comprising a frame and a diaphragm, the diaphragm having an effective length, wherein passage of air through the internal air passage induces vibration of the diaphragm across the effective length;
- an adjustment member rotatably engaged with the housing, the adjustment member being configured to adjust pressure against the frame according to a rotated position of the adjustment member relative to the housing, wherein the adjustment of pressure against the frame adjusts the effective length of the diaphragm.
A method for producing sound with an adjustable tone game call apparatus, the method comprising:
- providing an adjustable tone game call apparatus, comprising:
- a housing having an air inlet and an air outlet, the air inlet and outlet connected by a passage through the housing;
- a reed positioned in the passage;
- an adjustable member configured to rotate relative to the housing;
- inducing airflow through the passage to produce a first tone via vibration of the reed;
- rotating the adjustable member relative to the housing, wherein rotation of the adjustable member changes pressure applied to the reed;
- inducing airflow through the passage to produce a second tone via vibration of the reed, the second tone having a higher or lower pitch relative to the first tone.
A game call apparatus, comprising:
- a housing having an internal air passage, the internal air passage having an entrance opening and an exit opening;
- a reed positioned in the internal air passage between the entrance opening and the exit opening, the reed comprising a frame and a diaphragm, the diaphragm having an effective length, wherein passage of air through the internal air passage induces vibration of the diaphragm across the effective length;
- an adjustment member engaged with the housing and translatable relative to the housing, the adjustment member being configured to adjust pressure against the frame according to a translated position of the adjustment member relative to the housing, wherein the pressure against the frame adjusts the effective length of the diaphragm.
