UNIFIED WAVEFRONT FULL-RANGE WAVEGUIDE FOR A LOUDSPEAKER

A loudspeaker may include a full-range waveguide for creating a unified wavefront. The waveguide for use with a loudspeaker includes a plurality of entrances positioned at a first axial end of the waveguide and aligned along a first plane, each entrance configured to overlay a highfrequency transducer, a mouth disposed at a second axial end of the waveguide opposite the plurality of entrances, a contoured surface extending between the entrances and the mouth defining a cavity of the waveguide, the contoured surface defined by at least a first pair of walls positioned opposite one another, at least one integrator disposed between adjacent entrances and extending transversely between the first pair of walls, each integrator tapering towards the mouth to form a pointed edge along the direction of extension of the integrator, wherein each integrator has a pair of integrator surfaces angled with respect to one another, wherein each integrator surface including a solid portion and a perforated portion, and wherein the solid portion of each integrator surface is disposed adjacent the first pair of walls, wherein the solid portion and the perforated portion are separated by a straight line extending between the first pair of walls to form two trapezoidal regions, at least one acoustic opening disposed in each of the first pair of walls between a pair of integrators, the at least one acoustic opening overlaying at least a portion of a radiating surface of the at least one lower frequency transducer, and a contoured surface including at least one slot along the first pair of walls to receive the at least one integrator.
