Abstract

The assembly has a low audio frequency reproducing system i.e. caisson (1), placed in a space unique and distinct from a space containing loud-speakers that produce medium or high frequencies. The loudspeakers are placed at a top part of the assembly and wirelessly connected to the system and to a flat screen (3). The loud-speakers are situated on left and right pieces (2, 2') to be separated from both sides of the assembly. The pieces are rotated around their longitudinal axes according to a limited angular variation corresponding to a portion of circle.

Description

La présente invention concerne un dispositif monobloc et haute fidélité d'enceinte acoustique stéréophonique. Deux sortes d'enceintes acoustiques sont en vente sur le marché de la haute fidélité. La configuration la plus courante et la plus traditionnelle est celle des enceintes acoustiques regroupant dans un seul volume l'ensemble des haut parleurs grave, medium et aigu. Ce type de disposition conduit à avoir recours pour un effet stéréophonique à deux enceintes identiques en les plaçant face à l'auditeur et à une certaine distance l'une de l'autre. Ces enceintes, lorsqu'elles sont capables de délivrer fidèlement la plus grande partie du registre grave sont encombrantes et, même sous forme de colonnes, difficiles à intégrer. The present invention relates to a monobloc device and high fidelity stereophonic acoustic speaker. Two kinds of loudspeakers are on sale in the high fidelity market. The most common and most traditional configuration is that of speakers enclosing in a single volume all the speakers bass, mid and treble. This type of arrangement leads to use for a stereophonic effect to two identical speakers by placing them in front of the listener and at a certain distance from one another. These speakers, when they are able to faithfully deliver most of the bass register are cumbersome and, even in the form of columns, difficult to integrate.

Il existe par ailleurs, afin de palier cet inconvénient majeur, des systèmes comprenant des haut parleurs dissociés selon deux parties distinctes permettant de reproduire chacune d'une part le registre médium et aigu et, d'autre part le registre grave. Les fréquences graves jusqu'à 100 Hz n'étant pas directives, on utilise ainsi un ou deux caissons compacts placés près du sol et parfois amplifiés, qui sont chargés de reproduire ce registre. Ces caissons sont raccordés par des fils à un amplificateur et relayés également par fil afm de reproduire la partie supérieure du spectre sonore à deux paires de haut parleurs, voire plus pour les installations dites 5.1 pour le home cinéma . Ces deux types de solutions présentent donc chacune des inconvénients que la présente invention entend pouvoir pallier. L'ensemble, objet de la présente invention est constitué selon la Figure 1 qui représente juste pour l'exemple un caisson sans son piétement, et qui constitue un système acoustique unique (1) destiné à la reproduction des fréquences graves. Celui-ci est relié dans le même compartiment à des haut parleurs médiums aigus intégrés dans des modules escamotables. Comme représenté selon la figure 2, le coulissement des deux parties gauche droite (2) et (2') supportant les haut parleurs medium aigus permet, soit de replier ceux-ci totalement dans le meuble selon la Figure 1, soit au contraire de les écarter afin d'optimiser l'effet stéréophonique selon la Figure 2, tout en gardant ceux-ci en contact mécanique avec le système principal (1). Le fait qu'ils soient solidaires entre eux, mais cela n'est pas obligatoire, permet par ailleurs leur pivotement possible simultané dans le sens vertical, afin d'adapter la reproduction sonore stéréophonique en fonction du recul et de la position d'écoute de l'auditeur. Les avantages ainsi obtenus sont multiples : On dispose d'un seul volume de taille suffisante pour la reproduction optimisée des fréquences graves tout en divisant les coûts de fabrication par deux ainsi que l'encombrement correspondant par rapport à deux enceintes acoustiques traditionnelles. L'ensemble stéréophonique constitué de cette manière est pré câblé et ne nécessite ni fils de raccordement disgracieux, ni schémas de raccordement complexes des différents haut parleurs entre eux. 2 There is also, in order to overcome this major drawback, systems comprising dissociated speakers in two distinct parts for reproducing each on the one hand the midrange and treble and the other serious register. The low frequencies up to 100 Hz are not directives, so we use one or two compact boxes placed near the ground and sometimes amplified, which are responsible for reproducing this register. These boxes are connected by wires to an amplifier and relayed also by wire to reproduce the upper part of the sound spectrum to two pairs of speakers, or more for so-called 5.1 installations for the home theater. These two types of solutions therefore each have disadvantages that the present invention intends to overcome. The assembly, object of the present invention is constituted according to Figure 1 which is just for the example a box without its base, and which is a single acoustic system (1) for the reproduction of low frequencies. It is connected in the same compartment with high midrange speakers integrated in retractable modules. As shown in FIG. 2, the sliding of the two left-right parts (2) and (2 ') supporting the medium-high loudspeakers makes it possible either to fold these completely into the furniture according to FIG. 1, or to the contrary of the remove to optimize the stereophonic effect according to Figure 2, while keeping them in mechanical contact with the main system (1). The fact that they are integral with each other, but this is not mandatory, also allows their possible simultaneous pivoting in the vertical direction, in order to adapt the stereophonic sound reproduction according to the recoil and the listening position of the listener. The advantages thus obtained are multiple: There is only one volume of sufficient size for the optimized reproduction of low frequencies while dividing the manufacturing costs by two as well as the corresponding size compared to two traditional acoustic speakers. The stereophonic assembly constituted in this way is pre-wired and does not require unsightly connection wires or complex connection diagrams of the different speakers between them. 2

Le réglage, le raccordement et le positionnement des haut parleurs, par ailleurs, peut être optimisé une fois pour toutes et on dispose en outre d'un volume central dans lequel peuvent venir se grouper et se raccorder simultanément, de façon cohérente et simple, différents produits multimédia: amplificateur, ordinateur, écran (3), lecteur vidéo ou sonore. Le tout, compact et monobloc, est pour certaines version transportable le cas échéant. Pour des installations dites de type 5.1 ou plus, il peut en outre et de manière efficace au plan acoustique, grâce au positionnement en hauteur des haut parleurs medium aigus, être facile de mettre en oeuvre, toujours sans fils apparents et grâce à une liaison radio éventuelle et sans fil pour constituer les canaux arrières sonores face à un écran TV ou de vidéo projection. The adjustment, the connection and the positioning of the loudspeakers, moreover, can be optimized once and for all and one also has a central volume in which can be grouped and connected simultaneously, in a coherent and simple way, different multimedia products: amplifier, computer, screen (3), video or sound player. All, compact and monobloc, is for some transportable version if necessary. For so-called type 5.1 or higher installations, it can also be acoustically efficient, thanks to the height positioning of the medium high speakers, be easy to implement, still without visible wires and thanks to a radio link possible and wireless to form the rear sound channels facing a TV screen or video projection.
