Abstract:
1. A waveguide, comprising: a sound input portion having an input aperture configured to receive a sound signal from a sound source; a sound output portion spaced apart from the sound input portion, wherein a minimum distance between the sound input portion and sound output portion defines a depth of the waveguide; a plurality of isolated sound paths extending between the sound input portion and sound output portion and having substantially equal path lengths, each isolated sound path formed within a housing of the waveguide and configured to receive the sound signal from the input aperture such that the sound signal is divided into a plurality of sound signals, wherein each isolated sound path has a path with eater than the depth of the waveguide; and a plurality of plugs, wherein each plug divides an output of one of the isolated sound paths into a plurality of output sound paths and defines a plurality of output apertures of the waveguide, and wherein each output sound path is characterized by a reduced width relative to the output of the isolated sound path, the plurality of output apertures configured to output a combined sound signal based, at least in part, on the plurality of sound signals.
