Abstract
Disclosed herein are system, apparatus, article of manufacture, method and/or computer program product embodiments, and/or combinations and sub-combinations thereof, for a sound source with an array of slit shaped waveguide exits. An example embodiment of the sound source includes one or more drivers configured to receive an audio signal current and to generate pressurized air. The sound source further includes one or more chambers coupled to the one or more drivers and configured to direct the pressurized air from the one or more drivers. The sound source further includes an array of two or more slit shaped exits coupled to the one or more chambers and configured to receive the pressurized air from the one or more chambers and to emit sound waves. The directivity of the sound waves is controlled.
Claims20
A sound source, comprising:
- a driver configured to receive an audio signal current and to generate pressurized air;
- a plurality of chambers coupled to the driver and configured to direct the pressurized air from the driver;
- and
- a plurality of arrays of two or more slit shaped exits coupled to the plurality of chambers and configured to receive the pressurized air from the plurality of chambers and to emit sound waves,
- wherein a first array of the plurality of arrays of two or more slit shaped exits is coupled to a first chamber of the plurality of chambers and a second array of the plurality of arrays of two or more slit shaped exits is coupled to a second chamber of the plurality of chambers, and
- wherein a directivity of the sound waves is controlled based at least on a multimedia content associated with the audio signal current, an environment of the sound source, or a feedback from a user of the sound source.
A display device, comprising:
- a sound source, comprising:
- a driver configured to receive an audio signal current and to generate pressurized air;
- a plurality of chambers coupled to the driver and configured to direct the pressurized air from the driver;
- and
- a plurality of arrays of two or more slit shaped exits coupled to the plurality of chambers and configured to receive the pressurized air from the plurality of chambers and to emit sound waves, wherein a first array of the plurality of arrays of two or more slit shaped exits is coupled to a first chamber of the plurality of chambers and a second array of the plurality of arrays of two or more slit shaped exits is coupled to a second chamber of the plurality of chambers;
- and
- a controller configured to control directivity of the sound waves.
A display device, comprising:
- a sound source, comprising:
- a driver configured to receive an audio signal current and to generate pressurized air;
- a plurality of chambers coupled to the driver and configured to direct the pressurized air from the driver;
- and
- a plurality of arrays of two or more slit shaped exits coupled to the plurality of chambers and configured to receive the pressurized air from the plurality of chambers and to emit sound waves,
- wherein a first array of the plurality of arrays of two or more slit shaped exits is coupled to a first chamber of the plurality of chambers and a second array of the plurality of arrays of two or more slit shaped exits is coupled to a second chamber of the plurality of chambers, and
- wherein the first array of the plurality of arrays of two or more slit shaped exits comprises a matrix array of two or more slit shaped exits that are arranged in a square matrix arrangement;
- and
- a controller configured to control directivity of the sound waves based at least on a multimedia content associated with the audio signal current, an environment of the sound source, or a feedback from a user of the sound source.
