  • Patent number: 10397724
    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.

  • Publication number: 20170325019
    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.

  • Patent number: 7890312
    Abstract: A method is provided for predicting the performance of a loudspeaker port and optimizing port design. The method involves defining the geometries of a loudspeaker port, modeling the bi-directional fluid flow in the defined port utilizing a modeling method known as Computation Fluid Dynamics (“CFD”) and analyzing the flow model to determine whether the flow characteristic displayed in the model represent optimum flow characteristics for port performance. To optimize port design, the geometries of the port may be altered and modeled until the flow characteristic represents flow indicative of optimum port performance.
