High amplitude loudspeaker

摘要

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.

1. A speaker, comprising:
a housing having a first end, the first end having an acoustic aperture; a first electrode positioned in the housing a first distance from the first end, the first electrode biased to a first voltage; a second electrode positioned in the housing a second distance from the first end, the second distance greater than the first distance, the second electrode biased to a second voltage; and a diaphragm positioned in the housing between the first electrode and the second electrode, the diaphragm biased to a third voltage and including a valve, the valve is open when the diaphragm is moving in a first direction and closed when the diaphragm is moving in a second direction opposite the first direction.
