Abstract: A directivity pattern control (DPC) waveguide for a speaker is disclosed. The DPC waveguide comprises a body and first, second, and third drivers secured to the body. The body comprises a substantially planar portion having a planar surface, a waveguide portion having a waveguide surface contiguous with the flat surface, a first driver aperture at least substantially formed by the planar portion, a second driver aperture at least substantially formed by the planar portion, and a third driver aperture formed by the waveguide portion. The first driver propagates sound toward the first driver aperture, the second driver propagates sound toward the second driver aperture, and the third driver propagates sound toward the third driver aperture. The third driver is in a plane along an axis different than a plane for the first driver and the second driver. Also disclosed is a speaker including the DPC waveguide.

Abstract: A speaker having a continuous waveguide on one side of the speaker. The speaker includes a plurality of drivers that are superimposed to project sound into the continuous waveguide. The continuous waveguide is acoustically continuous in multiple dimensions.
