Loudspeaker enclosure element for forming vertical line array systems adjustable horizontal and vertical directivity

摘要

A sound reinforcement system is disclosed for the reproduction of wide-range high-power sound, which comprises several loudspeaker enclosures, each containing at least one driver (32) or loudspeaker with an emission throat (33), a duct (34) with parallel or inclined walls between the emission throat of the driver or loudspeaker and a diffraction slot (35), and a wave guide that continues from the diffraction throat onwards, consisting in divergent walls (36), of which the inclination of at least one can be varied. Each loudspeaker enclosure element (31) is equipped with mechanical parts on each side, for its connection to other identical enclosure elements, positioned vertically one above another and horizontally alongside one another, for a variation of the inclination of each enclosure element on the vertical plane, regulation of the wave guide aperture on the horizontal plan and regulation of vertical and horizontal sound dispersion.
