Abstract

L’invention concerne un appuie-tête (1) de siège comportant un dispositif de reproduction sonore, l’appuie-tête (1) comportant une face avant (10) destinée à accueillir la tête d’un occupant, une face arrière (12) située du côté opposé à la face avant, et deux faces latérales (14, 16) joignant les face avant et arrière ; l’appui-tête comportant au moins une enceinte (20, 21) formant une cavité interne de l’appuie-tête, l’enceinte (20, 21) comportant une ouverture avant fermée par un haut-parleur (22, 23) disposé sur la face avant (10), l’enceinte comportant en outre au moins une ouverture arrière fermée par un élément acoustiquement résistif (24, 25) disposé sur une face de l’appuie-tête (1) autre que la face avant (10), l’élément acoustiquement résistif étant configuré pour conformer la directivité du haut-parleur (22, 23) de manière à augmenter le niveau sonore émis par le haut-parleur vers l’avant tout en diminuant le niveau sonore émis vers l’arrière.
