Abstract

Enceinte acoustique ultra-plate à vibrations réduites Enceinte acoustique (100) comprenant un premier haut-parleur (26), un deuxième haut-parleur (28), un troisième haut-parleur (30) et un quatrième haut-parleur (32) structurellement analogues et définissant quatre axes centraux (D1, D2, D3, D4) parallèles à une même direction d’orientation (Z), les quatre haut-parleurs étant destinés à émettre un même signal sonore. Le premier haut-parleur et le troisième haut-parleur sont tournés dans un même sens et situés à un même niveau dans la direction d’orientation, et le deuxième haut-parleur et le quatrième haut-parleur sont tournés en sens opposé et situés à un même niveau selon la direction d’orientation. Les axes centraux définissent un parallélogramme (ABCD) en projection dans la direction d’orientation. Le premier haut-parleur et le deuxième haut-parleur présentent en fonctionnement un chevauchement (R’) dans la direction d’orientation. Figure pour l'abrégé : Figure 5
