(FR) HAUT-PARLEUR, DISPOSITIF INTEGRANT UN HAUT-PARLEUR, ET ENCEINTE POUR HAUT-PARLEUR
Abstract
(EN)
An apparatus (1) including a loudspeaker unit (10) comprising a housing (11) having walls (20, 28, 29) which enclose a continuous space (17), of which a first wall (20) has an opening (25) and at its outer side (20a), which is remote from the space, has a mounting surface (23) around the opening. The loudspeaker (30) is mounted on the mounting surface in such a way that it is situated outside the space and closes the opening. The mounting surface (23) is situated in a chamber (21) formed by a projecting portion of the first wall (20), which portion projects towards the space (17). The chamber is dimensioned in such a manner that at least a substantial part of the loudspeaker (30) is situated in the chamber.
(FR)
La présente invention concerne un dispositif (1) comprenant un haut-parleur et se composant d'une enceinte (11) présentant des parois (20, 28, 29) délimitant un espace continu (17). La première des parois (20) présente une ouverture (25), et sur sa face externe (20a) la plus éloignée dudit espace, une surface de fixation (23) entourant l'ouverture. Le haut-parleur (30) est fixé sur la surface de fixation de sorte qu'il soit situé à l'extérieur de l'espace et ferme l'ouverture. La surface de fixation (23) est située dans une chambre (21) formée par la partie saillante de première paroi (20), cette partie faisant saillie en direction dudit espace (17). Les dimensions de la chambre sont conçues de façon que la chambre puisse accueillir au moins une partie importante du haut-parleur (30).
