Title (EN) SOUND REPRODUCTION SYSTEM
(FR) SYSTÈME DE RESTITUTION SONORE
Abstract:
(EN) The invention relates to an assembly consisting of a motor vehicle and at least one sound reproduction system, comprising: at least one enclosure (22A) comprising at least one sound diffusion loudspeaker (28) that can emit sound waves; and at least one tubular sound diffusion line (23) comprising a wall (30) defining an internal conduit (31) for propagation of the sound waves emitted, the conduit (31) leading to a first end (32) of the sound diffusion line (23) to which the sound diffusion loudspeaker (28) is connected. The sound diffusion line (23) comprises at least three diffusion points (36) arranged throughout the wall (30), which are substantially aligned along the sound diffusion line (23), each diffusion point (36) being suitable for redirecting a portion of the sound waves propagated in the conduit (31) in order to respectively form a diffused sound wave.
(FR) L'invention concerne un ensemble comprenant un véhicule automobile et au moins un système de restitution sonore comprenant : - au moins une enceinte (22A) comprenant au moins un haut-parleur diffusif (28), apte à émettre des ondes sonores, et - au moins une ligne de diffusion sonore (23) tubulaire comprenant une paroi (30) définissant un conduit (31) interne de propagation des ondes sonores émises, le conduit (31) débouchant à une première extrémité (32) de la ligne de diffusion sonore (23) à laquelle est connecté le haut-parleur diffusif (28). La ligne de diffusion sonore (23) comprend au moins trois points de diffusion (36) disposés à travers la paroi (30), sensiblement alignés le long de la ligne de diffusion sonore (23), chaque point de diffusion (36) étant adapté pour rediriger une partie des ondes sonores propagées dans le conduit (31) pour former respectivement une onde sonore diffusée.
