1. An audio assembly comprising:
an elongated body that has a first end and a second end opposite the first end;
a diaphragm within the elongated body that extends from a first location that is proximate to the first end to a second location that is proximate to the second end and is configured to pivot about a pivot location that is proximate the second end;
a transducer within the elongated body and positioned proximate to the first end, the transducer configured to cause the diaphragm to pivot about the pivot location such that the diaphragm generates a positive acoustic pressure wave from a first surface of the diaphragm and a negative acoustic pressure wave from a second surface of the diaphragm, and for a given amount of displacement of the transducer, a portion of the diaphragm that is proximate to the transducer displaces more than a portion of the diaphragm that is proximate to the pivot location; and
a plurality of vent assemblies along one or more surfaces of the elongated body, the plurality of vent assemblies configured to vent the positive acoustic pressure wave and the negative acoustic pressure wave.
