Title (EN) MULTI-DRIVER ACOUSTIC HORN FOR HORIZONTAL BEAM CONTROL
(FR) PAVILLON ACOUSTIQUE À MULTIPLES MOTEURS POUR UNE COMMANDE DE FAISCEAU HORIZONTALE
Abstract:
(EN) A loudspeaker array has a cabinet in which is formed a continuously open circumferential horn for controlling sound produced by a number of transducers which are positioned in the cabinet, at a throat of the horn. The continuously open circumferential horn may 1) improve the power efficiency of the transducers without unwanted aliasing effects in audible frequency ranges and 2) provide vertical control for sound emitted by the transducers by flaring.
(FR) L’invention concerne un réseau de haut-parleurs qui a une enceinte dans laquelle est formé un pavillon circonférentiel ouvert de manière continue pour commander un son produit par un nombre de transducteurs qui sont positionnés dans l’enceinte, au niveau d’une gorge du pavillon. Le pavillon circonférentiel ouvert de manière continue peut 1) améliorer le rendement énergétique des transducteurs sans effets de crénelage indésirables dans des plages de fréquences audibles et 2) fournir une commande verticale pour un son émis par les transducteurs par élargissement.
