Patent ID: 7553210

Claim:
An apparatus for calling game comprising: a mouthpiece body comprising an air intake port and an opposing air exhaust port with a central region disposed along an internal airflow axis between said air intake port and said air exhaust port; said air intake port being sized and configured to cooperate with a human mouth and to have air blown into said air intake port by exhalation from said human mouth; said air intake port and said air exhaust port being configured in an axial relationship so that air blown into said air intake port flows along said internal airflow axis to said air exhaust port; said central region further comprising a diaphragm disposed centrally along said internal airflow axis and configured to vibrate and generate sound when air is blown into said air intake port; said central region further comprising a sound chamber dome disposed on a first side of said diaphragm; and said mouthpiece body further comprising a pliable segment oriented so that a manual exterior manipulation of said pliable segment, in a direction generally perpendicular to said airflow axis and on an opposite side of said diaphragm with respect to said sound chamber dome, causes said pliable segment to engage said diaphragm and move said diaphragm toward said sound chamber dome.
