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.
