Description

2905323 Agencement de haut-parleur dans une paroi de l'habitacle d'un2905323 Loudspeaker arrangement in a wall of the passenger compartment of a

véhicule automobile, notamment dans une porte L'invention concerne un agencement de haut-parleur dans une paroi de l'habitacle d'un véhicule automobile, et notamment dans une porte. Il est habituel de disposer un haut-parleur dans un panneau de garnissage d'une porte de véhicule automobile, comme connu par les documents FR 2 802 153 ou FR 2 752 263. Le panneau est fixé à la porte du véhicule, et le haut-parleur peut être incorporé dans une cavité formée dans le panneau lui servant de logement d'une part et jouant un rôle acoustique éventuel d'autre part. Un haut-parleur de véhicule automobile comprend classiquement un boîtier transformant l'énergie électrique en vibrations et une membrane acoustique, généralement conique, excitée par le boîtier et envoyant le son dans une direction privilégiée, coïncidant avec l'axe intérieur du cône de haut-parleur. Dans les modes de réalisation connus, la membrane acoustique du haut-parleur est dirigée vers l'intérieur de l'habitacle, et il est prévu dans le panneau d'habillage qui dissimule la haut-parleur au regard, des ouvertures sous forme de trous ou de grille devant la membrane pour que le son puisse être dirigé vers l'intérieur de l'habitacle. Cette solution connue présente des inconvénients dans la mesure où les trous ou les grilles nuisent à l'esthétique de l'habitacle. Le but de l'invention est de proposer un agencement de haut-parleur 25 qui remédie à ce problème tout en conciliant une bonne acoustique et un montage aisé. L'invention atteint son but grâce à un agencement de haut-parleur à boîtier et membrane acoustique dans une portion de paroi de l'habitacle d'un véhicule automobile, ladite portion de paroi comportant une cavité tournée 30 vers l'intérieur de l'habitacle, le haut-parleur étant fixé à l'avant de ladite cavité, caractérisé en ce que le haut-parleur est fixé avec sa membrane dirigée vers le fond de la cavité. Selon d'autres modes de réalisation, l'agencement présente une ou plusieurs des caractéristiques suivantes : 35 -il est prévu à l'avant de la cavité, une plaque d'habillage dont les bords 2905323 2 sont séparés des bords de la cavité par un espace, le haut-parleur étant disposé entre ladite cavité et ladite plaque d'habillage. -ladite plaque d'habillage est fixée, par exemple par des pattes de fixation, à la cavité. 5 -ladite plaque d'habillage comporte sur le côté tourné vers la cavité une concavité destinée à accueillir au moins partiellement le haut-parleur. -la plaque d'habillage est une plaque pleine. - le haut-parleur est fixé à la plaque d'habillage. -la cavité est de profondeur sensiblement uniforme, et peut avoir des 10 bords arrondis. - les bords de la cavité et de la plaque sont de même forme, par exemple rectangulaires ou circulaires. D'autres caractéristiques et avantages de l'invention apparaîtront à la lecture de la description suivante, en référence aux dessins annexés sur 15 lesquels : - la figure 1 représente en coupe horizontale l'agencement de haut-parleur conforme à l'invention dans une paroi verticale de véhicule. -la figure 2 représente en éclaté les différents constituants de l'agencement de la figure 1.  The invention relates to a loudspeaker arrangement in a wall of the passenger compartment of a motor vehicle, and in particular in a door. It is usual to have a loudspeaker in a trim panel of a motor vehicle door, as known from documents FR 2 802 153 or FR 2 752 263. The panel is attached to the vehicle door, and the top -parleur can be incorporated in a cavity formed in the panel serving as housing on the one hand and playing a possible acoustic role on the other. A motor vehicle loudspeaker conventionally comprises a housing transforming the electrical energy into vibrations and an acoustic membrane, generally conical, excited by the housing and sending the sound in a preferred direction, coinciding with the inner axis of the cone of loudspeaker. speaker. In the known embodiments, the acoustic membrane of the loudspeaker is directed towards the interior of the passenger compartment, and is provided in the covering panel which conceals the speaker from the view, openings in the form of holes. or grid in front of the membrane so that the sound can be directed towards the interior of the cabin. This known solution has disadvantages insofar as the holes or the grids detract from the aesthetics of the passenger compartment. The object of the invention is to provide a loudspeaker arrangement which overcomes this problem while reconciling good acoustics and easy assembly. The invention achieves its purpose by means of a speaker and acoustic diaphragm speaker arrangement in a wall portion of the passenger compartment of a motor vehicle, said wall portion having a cavity facing inwardly of the vehicle. cabin, the speaker being fixed to the front of said cavity, characterized in that the speaker is fixed with its membrane facing the bottom of the cavity. According to other embodiments, the arrangement has one or more of the following features: there is provided at the front of the cavity, a trim plate whose edges 2905323 2 are separated from the edges of the cavity by a space, the speaker being disposed between said cavity and said trim plate. the said dressing plate is fixed, for example by fixing lugs, to the cavity. 5 -ladite dressing plate has on the side facing the cavity a concavity intended to accommodate at least partially the speaker. the covering plate is a solid plate. - the loudspeaker is attached to the trim plate. the cavity is of substantially uniform depth, and may have rounded edges. - The edges of the cavity and the plate are of the same shape, for example rectangular or circular. Other characteristics and advantages of the invention will become apparent on reading the following description, with reference to the appended drawings, in which: FIG. 1 shows in horizontal section the loudspeaker arrangement according to the invention in a vertical wall of vehicle. FIG. 2 is an exploded view of the various constituents of the arrangement of FIG.

20 Les figures montrent une paroi d'habitacle de véhicule, ici sous forme d'une porte 1 dont la face intérieure, du côté de l'habitacle 3, est recouverte d'un panneau d'habillage 2, fixé sur la porte par des moyens de fixations 4 ou par encastrement ou emboîtement de manière classique. Le panneau 2 est globalement plan et comporte, selon l'invention, une cavité 5, ici sensiblement rectangulaire et de profondeur uniforme. Les côtés de la cavité se raccordent au fond plat selon un arrondi et se raccordent au plan du panneau 2 selon des bords sensiblement rectangulaires 6. Devant la cavité 5, donc du côté de l'habitacle 3, est fixée une plaque d'habillage 7 par des pattes de fixation 8 reliées au fond de la cavité 5. La plaque d'habillage 7 a sensiblement la forme extérieure de la cavité 5 : les bords 9 de la plaque 7 courent parallèlement aux bords 6 de la cavité, en laissant un espace E entre eux. La plaque 7 est partiellement convexe vers l'habitacle 3 et donc concave vers la cavité 5 de manière à agrandir l'espace disponible entre le fond de la cavité 5 et l'arrière de la plaque 7. On y loge le haut-parleur 10, dont le boîtier 11 est fixé par des pattes ou des vis 13 à la 3 2905323 plaque 7, et dont la membrane conique 12 s'ouvre à l'opposé de l'habitacle 3, vers le fond de la cavité 5. On n'a pas représenté les fils de connexion permettant le fonctionnement du boîtier 11. De la sorte, les ondes sonores S émises par la membrane 12 et dirigées 5 vers l'arrière sont réfléchies sur le fond de la cavité 5, formant caisse de résonance avec la plaque 7, et s'échappent principalement par l'espace E laissé entre les bords 9 de la plaque 7 et les bords 6 de la cavité 5. Ainsi le haut-parleur 10 est sensiblement invisible à l'oeil depuis l'intérieur de l'habitacle mais le son parvient dans l'habitacle, doté d'un effet 10 spatial dû aux réflexions arrière. Les caractéristiques sonores du son produit peuvent être choisies dans une large mesure en fonction des paramètres constructifs que sont la taille et la forme de la cavité et de la plaque ainsi que les matériaux les constituant (plastique, bois, etc.).The figures show a vehicle interior wall, here in the form of a door 1 whose interior face, on the side of the passenger compartment 3, is covered with a covering panel 2 fixed to the door by fixing means 4 or by embedding or interlocking in a conventional manner. The panel 2 is generally planar and comprises, according to the invention, a cavity 5, here substantially rectangular and of uniform depth. The sides of the cavity are connected to the flat bottom in a rounded manner and are connected to the plane of the panel 2 according to substantially rectangular edges 6. In front of the cavity 5, therefore on the side of the passenger compartment 3, is fixed a covering plate 7 by fixing lugs 8 connected to the bottom of the cavity 5. The covering plate 7 has substantially the outer shape of the cavity 5: the edges 9 of the plate 7 run parallel to the edges 6 of the cavity, leaving a space E between them. The plate 7 is partially convex toward the passenger compartment 3 and thus concave towards the cavity 5 so as to enlarge the space available between the bottom of the cavity 5 and the rear of the plate 7. The speaker 10 is housed therein , whose housing 11 is fixed by tabs or screws 13 to the plate 290 7, and whose conical membrane 12 opens opposite the passenger compartment 3, towards the bottom of the cavity 5. No The connection wires for the operation of the housing 11 are not shown. In this way, the sound waves S emitted by the membrane 12 and directed towards the rear are reflected on the bottom of the cavity 5 forming a sound box with the plate 7, and escape mainly by the space E left between the edges 9 of the plate 7 and the edges 6 of the cavity 5. Thus the speaker 10 is substantially invisible to the eye from the inside of the cabin but the sound arrives in the cabin, endowed with a spatial effect due to the rear reflections. The sound characteristics of the sound produced can be chosen to a large extent according to the constructive parameters such as the size and shape of the cavity and the plate and the materials constituting them (plastic, wood, etc.).

15 Un tel agencement est simple à mettre en oeuvre et permet d'intégrer le haut-parleur de manière invisible dans la porte. L'esthétique de l'habillage dépend des produits et des formes retenues. Une forme de plaque 7, telle que représentée, avec sa proéminence douce formée du côté de l'habitacle avec double courbure, réunit des qualités esthétiques et la possibilité de loger le 20 haut-parleur du côté opposé formant un creux. Quoique l'invention ait été décrite en référence aux panneaux de garnissage des portes d'un véhicule, elle s'applique à d'autres emplacements de haut-parleur sur une paroi de l'habitacle, qu'il s'agisse d'un panneau d'habillage de la carrosserie ou de la planche de bord ou de la plage arrière du 25 véhicule.Such an arrangement is simple to implement and makes it possible to integrate the loudspeaker invisibly into the door. The aesthetics of the dressing depends on the products and forms chosen. A plate shape 7, as shown, with its gentle prominence formed on the side of the passenger compartment with double curvature, combines aesthetic qualities and the possibility of housing the speaker on the opposite side forming a recess. Although the invention has been described with reference to the door trim panels of a vehicle, it applies to other speaker locations on a wall of the passenger compartment, whether it is a trim panel of the body or dashboard or the rear deck of the vehicle.
