Abstract

a. Enceinte à moteurs de haut-parleurs multiples. b. Enceinte caractérisée en ce qu'elle se compose d'un moyen définissant une cavité formée avec un ensemble correspondant d'ouvertures de moteurs recevant chacun un moteur correspondant d'un haut-parleur ainsi que des accessoires acoustiques, le moyen définissant la cavité ayant au moins une masse d'ouverture pour recevoir un moyen donnant une masse acoustique pour que la résonance avec les accessoires acoustiques à la fréquence de résonnance prédéterminée masse-accessoires se trouve dans la plage des basses fréquences audio, et un moyen pour réduire le coefficient Q du circuit résonnant formé par le moyen définissant la cavité.at. Multiple speaker motor enclosure. b. Enclosure characterized in that it consists of a means defining a cavity formed with a corresponding set of motor openings each receiving a corresponding motor of a loudspeaker as well as acoustic accessories, the means defining the cavity having at least minus an aperture mass for receiving an acoustic mass-providing means so that the resonance with the acoustic props at the predetermined resonant mass-prop frequency is in the low audio frequency range, and a means for reducing the Q coefficient of the resonant circuit formed by the means defining the cavity.
