Description

Ensemble de reproduction visuelle et sonore . Set of visual and sound reproduction.
L' invention concerne un ensemble de reproduction visuelle et sonore comportant une enceinte et un écran plat.The invention relates to a visual and sound reproduction assembly comprising an enclosure and a flat screen.
ARRIERE-PLAN DE L' INVENTIONBACKGROUND OF THE INVENTION
Les dispositifs de reproduction visuelle à écran plat présentent l'avantage d'être très compacts. Cependant, cette compacité limite en général la taille des haut-parleurs pouvant être intégrés dans le dispositif de reproduction visuelle, de sorte que la reproduction du son n'est pas optimale. En particulier, il est difficile de rendre correctement les basses fréquences.The flat screen video reproduction devices have the advantage of being very compact. However, this compactness generally limits the size of the speakers that can be integrated in the visual reproduction device, so that the sound reproduction is not optimal. In particular, it is difficult to correctly render low frequencies.
Pour palier cet inconvénient, il est connu d'utiliser un caisson de basse séparé formant enceinte, que l'on place en général sous le dispositif de reproduction visuelle. Cependant, ce caisson de basse est encombrant et nécessite des câblages longs et inesthétiques entre le dispositif de reproduction visuelle et le cais- son de basse.To overcome this drawback, it is known to use a separate subwoofer enclosure, which is usually placed under the visual reproduction device. However, this subwoofer is bulky and requires long and unsightly cabling between the visual reproducing device and the bass drum.
Il est connu du document EP 1 617 699 un pied recevant un écran plat, le pied portant une enceinte de sorte que l'enceinte s'étende derrière l'écran plat. De façon similaire, le document DE 29715306 décrit un pied portant une enceinte et sur lequel un écran plat est rapporté .It is known from EP 1 617 699 a foot receiving a flat screen, the foot carrying a speaker so that the enclosure extends behind the flat screen. Similarly, DE 29715306 discloses a foot with an enclosure and on which a flat screen is reported.
OBJET DE L'INVENTIONOBJECT OF THE INVENTION
L' invention vise à proposer un dispositif de reproduction visuelle et sonore particulièrement simple. BREVE DESCRIPTION DE L'INVENTIONThe aim of the invention is to propose a particularly simple visual and sound reproduction device. BRIEF DESCRIPTION OF THE INVENTION
Selon l'invention, on propose un ensemble de reproduction visuelle et sonore, comprenant :According to the invention, there is provided a set of visual and sound reproduction, comprising:
- un dispositif de reproduction visuelle comportant au moins un écran plat ; - un dispositif de reproduction sonore comprenant au moins une enceinte équipée d'au moins un transducteur électro-acoustique ;a visual reproduction device comprising at least one flat screen; - a sound reproduction device comprising at least one enclosure equipped with at least one electro-acoustic transducer;
Dans lequel le dispositif de reproduction visuelle et le dispositif de reproduction sonore comportent des moyens de leur solidarisation mutuelle de sorte que l'enceinte du dispositif de reproduction sonore s'étende directement derrière l'écran plat, caractérisé en ce que les moyens de solidarisation mutuelle comportent des éléments qui sont rapportés sur des organes d'accrochage équipant une face arrière du dispositif de reproduction visuelle et normalement destinés à accrocher le dispositif de reproduction visuelle à un mur ou à un support, lesdits éléments rapportés permettant la solidarisation d'au moins l'enceinte au dispositif de reproduction visuelle. Ainsi, on profite de l'espace derrière l'écran plat rendu libre par la compacité de l'écran plat pour y disposer l'enceinte du dispositif de reproduction sonore, qui est alors solidarisée à l'écran plat pour ne plus former qu'un ensemble unitaire. Le dispositif de repro- duction sonore est ainsi caché pour l'utilisateur et n'encombre plus l'espace environnant de l'écran plat. L' enceinte est alors disposée à proximité immédiate de l'écran plat, ce qui diminue considérablement la longueur des câbles de raccordement. Les fréquences basses visées se diffusent de façon omnidirectionnelle, de sorte que la disposition de l'enceinte derrière l'écran plat ne gêne pas la diffusion de sons de telles fréquences vers le spectateur se tenant face à l'écran plat. En outre, l'enceinte est rapportée directement sur le dispositif de reproduction visuelle, contrairement aux dispositifs connus dans lesquels l'enceinte est portée par le pied qui reçoit le dispositif de reproduction visuelle. A cet effet, les organes d'accrochage du dispo- sitif de reproduction visuelle sont détournés de leur fonction première qui est de permettre la solidarisation du dispositif de reproduction visuelle à un mur ou à un support (par exemple le pied des documents EP 1 617 699 ou DE 29715306) , et reçoivent maintenant des éléments qui permettent la solidarisation directe de l'enceinte au dispositif de reproduction visuelle.In which the visual reproduction device and the sound reproducing device comprise means for mutually interconnecting them so that the enclosure of the sound reproducing device extends directly behind the flat screen, characterized in that the means of mutual solidarity. comprise elements which are attached to fastening elements fitted to a rear face of the visual reproduction device and normally intended to hang the visual reproduction device on a wall or a support, said elements allowing the joining of at least one speaker to the visual reproduction device. Thus, we take advantage of the space behind the flat screen made free by the compactness of the flat screen to dispose the speaker of the sound reproduction device, which is then secured to the flat screen to form more than a unitary set. The sound reproducing device is thus hidden for the user and no longer clutter the surrounding space of the flat screen. The enclosure is then placed in the immediate vicinity of the flat screen, which considerably reduces the length of the connection cables. The target low frequencies are omnidirectionally distributed, so that the arrangement of the speaker behind the flat screen does not interfere with the broadcasting of sounds of such frequencies to the viewer standing in front of the flat screen. In addition, the enclosure is reported directly on the visual reproduction device, unlike known devices in which the enclosure is carried by the foot that receives the visual reproduction device. For this purpose, the attachment members of the visual reproduction device are diverted from their first function which is to allow the attachment of the visual reproduction device to a wall or a support (for example the foot of documents EP 1 617 699 or DE 29715306), and now receive elements that allow the direct attachment of the enclosure to the visual reproduction device.
Selon un mode particulier de réalisation, les éléments rapportés comportent de patères formant ensemble un berceau sur lequel l'enceinte est reçue. BREVE DESCRIPTION DES DESSINSAccording to a particular embodiment, the reported elements comprise hooks together forming a cradle on which the enclosure is received. BRIEF DESCRIPTION OF THE DRAWINGS

DESCRIPTION DETAILLEE DE L'INVENTION En référence à la figure 1, et conformément à un premier mode particulier de réalisation de l'invention, l'ensemble de reproduction visuelle et sonore comporte un dispositif de reproduction visuelle sous la forme d'un téléviseur à écran plat 1. De façon classique, le téléviseur 1 est équipé en face arrière d' inserts taraudés 2 pour permettre son éventuelle fixation à un mur. Selon l'invention, on équipe le téléviseur 1 de patères 3 qui sont fixées à la face arrière de celui-ci au moyen de vis 4 reçues dans les inserts 2. Les patères 3 forment ainsi un berceau adapté à recevoir un dispositif de reproduction sonore 5.DETAILED DESCRIPTION OF THE INVENTION Referring to FIG. 1, and according to a first particular embodiment of the invention, the visual and sound reproduction assembly includes a visual reproduction device in the form of a screen television. flat 1. Conventionally, the TV 1 is equipped on the rear face with threaded inserts 2 to allow its possible attachment to a wall. According to the invention, the TV 1 is equipped with hooks 3 which are fixed to the rear face thereof by means of screws 4 The hooks 3 thus form a cradle adapted to receive a sound reproduction device 5.
Comme cela est visible à la figure 2, le disposi- tif de reproduction sonore 5 comporte un caisson ayant la forme générale d'un parallélépipède allongé. Le caisson définit ici deux enceintes de basse 6 accolées par leurs petites faces. Chacune des enceintes de basse 6 est équipée de deux haut-parleurs de basse 7, et comporte un évent équipé d'une tuyère 8 (plus particulièrement visible à la figure 1) . Les haut-parleurs 7 sont ici installés sur une face du dispositif de reproduction sonore 5 opposée à celle qui s'étend en regard du téléviseur (celui-ci est figuré en pointillés sur la figure 2) . Un obs- tacle, ici une simple tôle métallique 9, s'étend en regard des haut-parleurs 7 à très petite distance de la paroi en regard du caisson, de l'ordre de quelques millimètres (sur la figure 2, cette distance a été exagérée relativement aux dimensions du caisson, pour plus de clar- té) . L'obstacle 9 définit avec la membrane du haut- parleur un volume d'air ouvert sur l'extérieur par une ouverture périphérique de faible hauteur h définie par la distance entre l'obstacle 9 et le rebord périphérique du haut-parleur (ou la paroi du caisson, si ledit rebord ne saille pas de la paroi) . Les mouvements convectifs de l'air poussé par la membrane du haut-parleur sont ainsi contrariés, particulièrement aux grandes excursions des bobines des haut-parleurs de basse 7 créant des mouvements convectifs macroscopiques de l'air. La résistance opposée au passage de l'air par cette petite ouverture périphérique, du fait des frottements visqueux internes à l'air au passage de l'ouverture périphérique 15, crée une charge aérodynamique du haut-parleur augmentant avec le déplacement de la membrane du haut-parleur. Il convient donc de disposer l'obstacle à une distance de la paroi de l'enceinte qui soit suffisante pour permettre un mouvement aisé de la membrane aux petites puissances, mais pas trop grande pour réguler les excursions importantes aux hautes puissances, et ainsi éviter les excursions qui conduiraient à l'affolement du haut-parleur. Cette charge aérodynamique par obstacle, très simple et peu coûteuse à mettre en œuvre, permet d'éviter l'utilisation d'un contrôle actif des haut-parleurs particulièrement délicat à mettre au point. Le caisson porte en outre, aux extrémités des enceintes de basse 6, deux haut-parleurs médium-aigus 10 qui rayonnent latéralement vers l'extérieur. Or le son rayonné par ces haut-parleurs est beaucoup plus directionnel que le son émis au moyen des enceintes de basse 6. Il convient donc de renvoyer le son vers une zone en face du téléviseur, ou se tiennent habituellement les téléspectateurs. A cet effet, des réflecteurs 11, formés ici par des extrémités recourbées de la tôle métallique 9 qui sert à charger les haut-parleurs de basse 7, s'étendent pour définir avec la paroi arrière du téléviseur 1 des guides acoustiques 12 qui guident le son rayonné par les haut-parleurs 10 vers le téléspectateur. Des essais d'écoute ont permis de constater que les réflecteurs 11 induisent un effet de spatialisation marqué entre le son provenant du haut-parleur 10 gauche et le son provenant du haut-parleur 10 droit, permettant des effets sonores intéressants.As can be seen in FIG. 2, the sound reproducing device 5 comprises a box having the general shape of an elongate parallelepiped. The box here defines two bass speakers 6 contiguous by their small faces. Each of the bass speakers 6 is equipped with two bass speakers 7, and has a vent equipped with a nozzle 8 (more particularly visible in Figure 1). The speakers 7 are here installed on one side of the sound reproduction device 5 opposite to that which extends opposite the television (it is shown in dashed lines in Figure 2). An obstacle, in this case a simple metal sheet 9, extends opposite the loudspeakers 7 at a very short distance from the wall facing the box, of the order of a few millimeters (in FIG. been exaggerated with regard to the dimensions of the box, for more clarity). The obstacle 9 defines with the membrane of the loudspeaker a volume of air open to the outside by a peripheral opening of low height h defined by the distance between the obstacle 9 and the peripheral rim of the speaker (or the wall of the box, if said flange does not protrude from the wall). The convective movements of the air pushed by the speaker's membrane are thus thwarted, particularly at large excursions of the coils of the bass speakers 7 creating macroscopic convective motions of the air. The resistance opposed to the passage of air through this small peripheral opening, because of the viscous friction internal to the air at the passage of the peripheral opening 15, creates an aerodynamic load of the loudspeaker increasing with the displacement of the membrane of the loud speaker. It is therefore advisable to arrange the obstacle at a distance from the wall of the enclosure is sufficient to allow easy movement of the membrane to small powers, but not too large to regulate important excursions at high power, and thus avoid excursions that would lead to panic loudspeaker. This aerodynamic obstacle load, very simple and inexpensive to implement, avoids the use of active control of the speakers particularly difficult to develop. The box further carries, at the ends of the bass speakers 6, two midrange speakers 10 which radiate laterally outwardly. But the sound radiated by these speakers is much more directional than the sound emitted by the bass speakers 6. It should therefore return the sound to an area in front of the TV, or are usually held viewers. For this purpose, reflectors 11, formed here by curved ends of the metal sheet 9 which serves to charge the bass speakers 7, extend to define with the rear wall of the TV 1 acoustic guides 12 which guide the its radiated by the speakers 10 to the viewer. Hearing tests have shown that the reflectors 11 induce a marked spatialization effect between the sound coming from the left speaker and the sound coming from the right speaker, allowing interesting sound effects.
Sur la figure 3, on constate que le caisson du dispositif de reproduction sonore 5 est entièrement caché derrière le téléviseur 1. Seuls dépassent sur les côtés du téléviseur 1 les réflecteurs 11, donnant à l'ensemble une esthétique particulièrement intéressante. L'ensemble de reproduction visuelle et sonore ainsi constitué forme un ensemble autonome, ne reposant que sur le pied du té- léviseur. Selon un deuxième mode particulier de réalisation illustré à la figure 4, on équipe le téléviseur 1 d'une barre 20 qui est fixée à la face arrière du téléviseur 1 au moyen de pattes de fixation 21 vissées dans les in- serts du téléviseur 1. Sur la barre 20 est rapportée un caisson de basse 22 équipé de crochets 23 pour son accrochage à la barre 20. Le caisson de basse 22 forme une enceinte unique équipée d'un haut-parleur de, basse 25 débouchant sur une paroi opposée au téléviseur 1. L'enceinte comporte un évent 26.In Figure 3, we see that the housing of the sound reproduction device 5 is completely hidden behind the TV 1. Only beyond the sides of the TV 1 reflectors 11, giving the whole aesthetic particularly interesting. The set of visual and sound reproduction thus formed forms an autonomous unit, resting only on the foot of the television. According to a second particular embodiment illustrated in FIG. 4, the television set 1 is equipped with a bar 20 which is fixed to the rear face of the television set 1 by means of fixing lugs 21 screwed into the inserts of the television set 1. On the bar 20 is reported a subwoofer 22 equipped with hooks 23 for attachment to the bar 20. The subwoofer 22 forms a single speaker equipped with a speaker of low 25 opening on a wall opposite the TV 1. The enclosure has a vent 26.
Le caisson de basse 22 est également équipé de pieds en matériau élastomère 24 pour son appui contre la face arrière du téléviseur 1. Les pieds 24 contribuent à amortir les éventuelles vibrations engendrées par le caisson de basse 22.The subwoofer 22 is also equipped with feet of elastomeric material 24 for its support against the rear face of the television 1. The feet 24 help dampen any vibrations generated by the subwoofer 22.
Selon un aspect particulier de l'invention, la barre 20 dépasse de part et d'autre du téléviseur 1 pour recevoir deux caissons auxiliaires 27 sur lesquels des haut-parleurs medium-aigus sont montés pour rayonner di- rectement vers une zone en face de l'écran plat où se tient le téléspectateur. Les caissons auxiliaires 27 sont équipés de fixations 28 à la barre 20 permettant l'orientation angulaire des caissons auxiliaires 27.According to a particular aspect of the invention, the bar 20 protrudes from both sides of the television 1 to receive two auxiliary boxes 27 on which medium-high speakers are mounted to radiate directly to an area in front of the flat screen where the viewer stands. The auxiliary caissons 27 are equipped with fasteners 28 to the bar 20 allowing the angular orientation of the auxiliary caissons 27.
Comme cela est visible à la figure 5, le caisson de basse 22 s'étend derrière le téléviseur 1 et est entièrement caché par ce dernier. Seuls sont visibles les caissons auxiliaires 27 de part et d'autre du téléviseur 1.As shown in Figure 5, the subwoofer 22 extends behind the TV 1 and is completely hidden by the latter. Only the auxiliary boxes 27 are visible on either side of the television 1.
L'invention n'est pas limitée à ce qui vient d'être décrit, mais bien au contraire englobe toute variante entrant dans le cadre défini par les revendications .The invention is not limited to what has just been described, but on the contrary encompasses any variant within the scope defined by the claims.
En particulier, il convient, le cas échéant, de prévoir tout moyen d'amortissement, par exemple intégré dans les moyens de solidarisation mutuelle, propre à iso- 1er le dispositif de reproduction visuelle des éventuelles vibrations engendrées par le dispositif de reproduction sonore. In particular, it is appropriate, where appropriate, to provide any damping means, for example integrated in the means of mutual solidarity, specific to iso- 1st the device for visual reproduction of any vibrations generated by the sound reproduction device.
