Abstract: Disclosed is an acoustic device comprising an enclosed housing defining an inner volume and having a front and a back; an acoustic port penetrating the front of the enclosed housing; a first and second sense structure attached to the inside of the housing and defining a gap between the first and second sense structures; a front volume defined by the portion of the inner volume between the first sense structure and the front of the housing; a back volume defined by the portion of the inner volume between the second sense structure and the back of the housing; and at least one vent in the first sense structure operatively connecting the front volume and the gap, wherein the acoustic device has a cutoff frequency above approximately 100 Hz.

Abstract: A speaker. The speaker includes a housing, a first electrode, a second electrode, and a diaphragm. The housing has a first end, the first end which includes an acoustic aperture. The first electrode is positioned in the housing a first distance from the first end, and is biased to a first voltage. The second electrode is positioned in the housing a second distance, which is greater than the first distance, from the first end. The second electrode is biased to a second voltage. The diaphragm is positioned in the housing between the first electrode and the second electrode, and is biased to a third voltage. The speaker includes a valve. The valve opens when the diaphragm is moving away from the first end and closes when the diaphragm is stationary or moving toward the first end. When the valve is closed, the diaphragm forms an air-tight seal between the first end and the second electrode.
