    Abstract: One embodiment provides a speaker device comprising a first housing including a first top surface comprising a first opening, a first recessed mounting surface spaced below the first opening, and a first recessed sidewall extending upwardly from the first recessed mounting surface to the first opening to form a first waveguide. The speaker device further comprises a first upward-facing driver mounted into the first recessed mounting surface. The first waveguide shapes propagation of acoustic energy generated by the first upward-facing driver to project the acoustic energy out of the speaker device in an upwardly inclined direction.

    Abstract: One embodiment provides a method that includes optimizing a shape for a port tube of a speaker device by varying a portion of multiple initial port tube design parameters and iteratively repeating an execution of a simulation computing process that simulates shear measure until the execution of the simulation computing process minimizes the simulated shear measure and outputs a final port tube design for an improved port tube having an optimized central portion and an optimized flare shape of at least one flared exit based on multiple final port tube design parameters for an improved shape for the port tube that maximally delays an onset of turbulence and flow separation for improved low frequency output for the speaker device. The improved port tube is generated using the multiple final port tube design parameters.

    Abstract: One embodiment provides a method comprising determining an actual elevation of a sound source. The actual elevation is indicative of a first location at which the sound source is physically located relative to a first listening reference point. The method further comprises determining a desired elevation for a portion of an audio signal. The desired elevation is indicative of a second location at which the portion of the audio signal is perceived to be physically located relative to the first listening reference point. The desired elevation is different from the actual elevation. The method further comprises, based on the actual elevation, the desired elevation and the first listening reference point, modifying the audio signal, such that the portion of the audio signal is perceived to be physically located at the desired elevation during reproduction of the audio signal via the sound source.
