A waveguide () comprising a shell () having an inlet opening () intended to receive acoustic energy and an outlet opening () for emitting acoustic energy; and a phase plug () located into the shell () so as to define therebetween a pathway (W) for the acoustic energy from the inlet opening () to the outlet opening (). The acoustic pathway (W) has a longitudinal extension direction (D) between the openings () and the directions of all longitudinal splines (S, S, S, S, S, S) of the pathway (W) are perpendicular to the inlet opening () at the inlet opening () on one ideal longitudinal surface.

Isophasic waveguide for a loudspeaker

Audio loudspeakercan be arranged in various vertical arrays, such asor. Each loudspeakerincludes a generally trapezoidal-shaped housingcomposed of two forwardly projecting lobe sections. A pair of low-frequency cone transducersare housed in the lobe sections. A vertically arranged setof high-frequency compression drivers are positioned centrally in the housing to project in the forward direction. Three mid-frequency cone transducersare vertically arranged along opposite sides of the high frequency drivers. Each of the low-, mid-, and high-frequency transducers are individually powered and controlled by a separate DSP channel.

Method and system for large scale audio system

Audio loudspeakercan be arranged in various vertical arrays, such as. Each loudspeakeris identical in construction and includes a housinggenerally in the shape of a rectangular cuboid. A pair of ultra low-frequency transducersare positioned in the housing. Each of the ultra low-frequency transducers is individually powered and controlled by a separate DSP channel, thereby to directionally steer the transducer output.

The horn structure () is composed of a vertical array of horn pairs (A-G) arranged in stacked relationship to each other. The horns (L andR) of each pair have entrance openings (L andR) at the same elevation and disposed side-by-side to each other. The mouths (L andR) of the horn pairs are in directional alignment with each other and stacked vertically on top of each other.

Acoustic horn manifold

The acoustic horn manifold () is composed of a vertical array of horn pairs (A-G) arranged in stacked relationship to each other. The horns (L andR) of each pair have entrance openings (L andR) on first common planeand at the same elevation and disposed side-by-side to each other. The mouths (L andR) of the horn pairs are in directional alignment with each other and stacked vertically on top of each other. The mouths may be laterally offset somewhat from each other and/or may extend forwardly from respective horn entrances at different distances from each other.
