Abstract

The device has front loudspeakers (2), and rear loud speakers (3) inclined toward top. The front and rear loud speakers are arranged such that sound produced by the loudspeaker simultaneously is spread toward opposite stereo axes. The sound produced by the rear loudspeakers is reflected toward front of the device by a vertical wall (8) i.e. LCD screen, placed behind the rear loudspeakers. The rear loudspeakers are oriented toward rear according to an angle ranging between 25 and 70 degrees with respect to horizontal direction. The rear loudspeakers are provided above the front loudspeakers.

Description

La présente invention concerne un dispositif monobloc et stéréophonique d'enceinte acoustique amplifiée.The present invention relates to a monobloc device and stereophonic amplified acoustic speaker.

Il existe sur le marché audio de nombreuses sortes d'enceintes acoustiques et de systèmes stéréophoniques mais on peut distinguer schématiquement à l'intérieur de ce marché deux grandes familles de produits : les enceintes acoustiques de sol, d'une part, dédiées en premier lieu aux installations haute fidélité ou dites de « home cinéma » et, d'autre part, les enceintes acoustiques conçues pour être posées sur une table ou sur une bibliothèque, généralement moins coûteuses et moins performantes mais dont l'usage s'est beaucoup développé récemment, notamment dans le cadre de l'amélioration de la qualité sonore des fichiers stockés sur ordinateurs.There are many kinds of loudspeakers and stereophonic systems on the audio market, but two large product families can be distinguished schematically within this market: the acoustic loudspeakers on the one hand, dedicated in the first place high-fidelity or so-called "home theater" installations and, on the other hand, loudspeakers designed to be placed on a table or a bookcase, which are generally less expensive and less efficient, but whose use has developed considerably recently , particularly in the context of improving the sound quality of files stored on computers.

Ce type d'enceintes acoustiques est souvent disposé de façon aléatoire sur des supports horizontaux, tels que les plans de travail, en particulier les tables ou bureaux, en fonction de la place et de la surface disponibles concernées. Ces enceintes sont ainsi situées plus ou moins en face de l'auditeur et préférablement, si celui-ci est placé au centre de celles-ci, de manière à ce qu'elles puissent délivrer un effet stéréophonique. La faible taille en hauteur de celles ci, l'absence de recul suffisant de l'auditeur, les réflexions induites par tout plan horizontal qui est situé à proximité ainsi que l'écartement des enceintes, choisi ou obligatoire, et trop souvent inapproprié, sont autant de freins à une écoute de qualité.This type of loudspeaker is often randomly placed on horizontal supports, such as worktops, especially tables or desks, depending on the available space and available space. These speakers are thus located more or less in front of the listener and preferably, if it is placed in the center of them, so that they can deliver a stereophonic effect. The small height in height of these, the lack of sufficient distance of the listener, the reflections induced by any horizontal plane which is located nearby as well as the spacing of the enclosures, chosen or obligatory, and too often inappropriate, are many brakes to quality listening.

Afin de pallier cet inconvénient, il est possible d'avoir recours à la catégorie des enceintes acoustiques de sol, disposées alors de chaque coté du plan de travail, tel que table ou bureau, concerné. Toutefois, dans le cadre d'une utilisation stéréophonique à partir d'un lieu d'écoute situé au devant d'un tel plan de travail et d'une position assise de l'auditeur qui se situerait idéalement au milieu dudit plan de travail, on dispose d'un angle d'écoute très réduit par rapport aux dits haut-parleurs ; ceux-ci sont en effet disposés alors presque à angle droit et souvent en contrebas de part et d'autre des oreilles de l'auditeur, qui n'est plus en mesure ainsi de percevoir de façon satisfaisante ni l'effet stéréophonique ni la totalité du spectre médium aigu, compte tenu de la forte atténuation provenant de l'angle d'écoute réduit dont il dispose. De plus, l'implantation de ce type d'enceinte raccordée à ses différents équipements interdit dans la pratique à ce plan de travail horizontal toute espèce de mobilité.To overcome this drawback, it is possible to use the category of floor acoustic speakers, then arranged on each side of the worktop, such as table or desk, concerned. However, in the context of a stereophonic use from a listening place located in front of such a work plan and a sitting position of the listener which would be located ideally in the middle of said work plan, there is a very small listening angle compared to said speakers; these are indeed arranged then almost at right angles and often below both ears of the listener, which is no longer able to perceive satisfactorily either the stereophonic effect or the totality of the acute mid-spectrum, given the high attenuation resulting from the reduced listening angle at its disposal. In addition, the implementation of this type of enclosure connected to its various equipment prohibits in practice this horizontal work plan any kind of mobility.

Le dispositif, objet de la présente invention, a pour objectif de pallier ces différents inconvénients et est muni de haut-parleurs de façade (2) et de haut-parleurs arrières (3), ces derniers étant inclinés vers le haut, lesdits haut-parleurs de façade (2) et arrières (3) étant disposés de telle sorte que les sons produits sont simultanément diffusés vers deux axes stéréophoniques opposés.The device, object of the present invention, aims to overcome these disadvantages and is provided with front speakers (2) and rear speakers (3), the latter being inclined upwards, said high-speakers front (2) and rear (3) speakers being arranged so that the produced sounds are simultaneously broadcast to two opposite stereophonic axes.

Selon un mode préférentiel de réalisation, les haut-parleurs (3) sont orientés vers l'arrière et vers le haut selon un angle variant préférentiellement, mais ce n'est pas obligatoire, entre 25° et 70° par rapport au plan horizontal d'écoute.According to a preferred embodiment, the loudspeakers (3) are oriented rearwardly and upwardly at a preferentially varying angle, but this is not mandatory, between 25 ° and 70 ° relative to the horizontal plane of 'listening.

Ledit angle peut aussi éventuellement être réglable en fonction des caractéristiques du local d'écoute et de la position d'écoute de l'auditeur en hauteur (angle grand pour une position assise et angle petit pour une position debout qui varie respectivement de 90° à 45° et de 45° à 0°).Said angle can also possibly be adjustable according to the characteristics of the listening room and the listening position of the listener in height (large angle for a sitting position and small angle for a standing position which varies respectively from 90 ° to 45 ° and 45 ° to 0 °).

D'autres caractéristiques du dispositif selon la présente invention ressortiront mieux à la lecture de la description qui va suivre en faisant référence aux figures suivantes :

  • la Figure 1 est une vue en coupe transversale du dispositif selon l'invention ;
  • la Figure 2 est une vue en plan du même dispositif où sont représentées schématiquement les zones optimales d'écoute représentées sur un plan horizontal ;
  • la Figure 3 illustre une vue en coupe transversale d'un autre mode de réalisation du dispositif selon l'invention ;
  • la Figure 4 est une vue en coupe transversale d'une variante du dispositif illustré à la Figure 3.
Other features of the device according to the present invention will become more apparent on reading the description which follows, with reference to the following figures:
  • the Figure 1 is a cross-sectional view of the device according to the invention;
  • the Figure 2 is a plan view of the same device which schematically shows the optimal listening areas represented on a horizontal plane;
  • the Figure 3 illustrates a cross-sectional view of another embodiment of the device according to the invention;
  • the Figure 4 is a cross-sectional view of a variant of the device illustrated in FIG. Figure 3 .

Le dispositif selon l'invention, référence étant faite à la Figure 1 et à la Figure 2 est constitué d'un meuble ou plan de travail, en particulier une table ou un bureau, qui regroupe un système acoustique monobloc (1) doté de haut parleurs en façade (2), orientés de manière classique vers des auditeurs placés à distance de ceux-ci. Lesdits haut-parleurs (2) sont reliés, mais ce n'est pas obligatoire, par au moins un haut parleur de graves. Par ailleurs, des haut-parleurs stéréophoniques complémentaires (3) sont placés en arrière de façon symétriquement opposée aux dits haut-parleurs (2) et de telle manière que lesdits haut-parleurs (3) puissent diffuser le son de façon inclinée vers le haut et dans la direction opposée de celle des haut-parleurs de façade (2). Afin d'optimiser les effets de réflexion, l'angle d'inclinaison desdits haut- parleurs (3) pourra être variable de façon à former préférentiellement un angle incident variant entre 25° et 70° par rapport à l'horizontale. Le dispositif, afin d'obtenir un effet de réflexion optimal, sera préférablement placé à proximité de, ou avantageusement contre, un mur standard, ou une paroi verticale, (8) ce qui permettra de rediffuser les fréquences élevées. Le support des dits haut-parleurs arrières (3) pourra par ailleurs être indifféremment fixe ou au contraire réglable afin d'obtenir un angle variable.The device according to the invention, reference being made to the Figure 1 and at the Figure 2 consists of a piece of furniture or worktop, in particular a table or a desk, which groups together a one-piece acoustic system (1) with front speakers (2), oriented conventionally towards listeners placed at a distance from those -this. Said speakers (2) are connected, but it is not mandatory, by at least one subwoofer. Furthermore, complementary stereophonic loudspeakers (3) are placed behind symmetrically opposite said loudspeakers (2) and in such a way that said loudspeakers (3) can diffuse sound upwardly in an inclined manner. and in the opposite direction of that of the front loudspeakers (2). In order to optimize the reflection effects, the inclination angle of said loudspeakers (3) may be variable so as to preferentially form an incident angle varying between 25 ° and 70 ° relative to the horizontal. The device, in order to obtain an optimal reflection effect, will preferably be placed near, or advantageously against, a standard wall, or a vertical wall, (8) which will make it possible to redistribute the high frequencies. The support of said rear speakers (3) may also be indifferently fixed or on the contrary adjustable to obtain a variable angle.

Sur la Figure 2, pour une plus grande clarté de la démonstration et du schéma concernés il sera admis par hypothèse que la qualité de la perception d'un son haute fidélité stéréophonique commence à s'atténuer sensiblement de manière générale dans les fréquences élevées et sur un plan latéral au-delà de 30° par rapport à l'axe des haut-parleurs. Et cela même s'il est établi que le phénomène est en réalité progressif de 0 à 90° et que la perception de ce phénomène dépend de différents facteurs comme la configuration des murs et l'aménagement du local d'écoute ou la directivité intrinsèque des haut parleurs medium/aigus concernés. On peut constater ici que cette même zone d'écoute optimale est répertoriée en (4) dans la Figure 1 et (4') dans la Figure 2 ; contrairement à la zone (4) de la Figure 1, la zone (4') de la Figure 2 est située à une certaine distance du meuble (1), compte tenu des contraintes latérales liées à l'effet stéréophonique. Comme on le constate d'après la même Figure 2, l'action complémentaire des haut-parleurs (3) qui sont orientés vers un mur, dans le but de diffuser un son réfléchi, représenté ici à 30° sur le schéma (Figure 2), permet à l'auditeur de s'approcher sans inconvénient au plus près du meuble ou du bureau, en position (5), et ce, à l'intérieur de la portion définie par l'espace (7'). Ledit espace élargi lui permet de se mouvoir comme en position (6) à distance du meuble, de façon plus libre, mais tout en restant à l'intérieur de ladite zone (7') d'écoute optimale.On the Figure 2 for the sake of clarity of the demonstration and the scheme concerned, it will be assumed that the quality of the perception of stereophonic high fidelity sound begins to diminish noticeably in general at high frequencies and at a lateral more than 30 ° with respect to the axis of the loudspeakers. And this, even if it is established that the phenomenon is actually progressive from 0 to 90 ° and that the perception of this phenomenon depends on various factors such as the configuration of the walls and the layout of the listening room or the intrinsic directivity of the rooms. medium / high speakers concerned. It can be seen here that this same optimal listening area is listed in (4) in the Figure 1 and (4 ') in the Figure 2 ; unlike zone (4) of the Figure 1 , the zone (4 ') of the Figure 2 is located at a distance from the cabinet (1), given the lateral constraints related to the stereophonic effect. As can be seen from the same Figure 2 , the complementary action of the speakers (3) which are directed towards a wall, in order to diffuse a reflected sound, represented here at 30 ° in the diagram ( Figure 2 ), allows the listener to approach without inconvenience closer to the furniture or the office, in position (5), and this, inside the portion defined by the space (7 '). Said enlarged space allows it to move as in position (6) away from the furniture, more freely, but while remaining within said optimal listening area (7 ').

Le dispositif tel qu'ainsi défini permet de diriger selon plusieurs cas de figure le son vers l'auditeur lorsque celui-ci est situé hors du champ de la zone d'écoute qualitativement souhaitée (4) ou (4') des haut-parleurs de façade (2).The device as defined in this way makes it possible, in several cases, to direct the sound towards the listener when it is located outside the field of the qualitatively desired listening area (4) or (4 ') of the loudspeakers. facade (2).

En effet, dans toutes les hypothèses où les oreilles de l'auditeur se trouveront, soit pour une position assise de celui-ci à un bureau (position globalement référencée 5) ou devant un écran, soit pour une position debout dans une zone à proximité d'un meuble quelconque ou d'un bureau équipé de ces haut-parleurs arrières (position globalement référencée 6), les haut-parleurs (3) qui utilisent la réflexion murale ou celle d'un écran vertical seront en mesure de prendre le relais dans la zone (7) et (7') là où les haut-parleurs (2) auront cessé d'être efficaces.Indeed, in all cases where the ears of the listener will be, either for a sitting position of it to a desk (position referenced globally 5) or in front of a screen, or for standing in a nearby area of any piece of furniture or of an office equipped with these rear loudspeakers (position generally referenced 6), the loudspeakers (3) which use the reflection of wall or that of a vertical screen will be able to take the relay in the zone (7) and (7 ') where the loudspeakers (2) have ceased to be effective.

Les avantages ainsi obtenus sont multiples : on dispose, dans un système unique et monobloc, de la possibilité de diffuser un son dont le rendu sera parfaitement calibré à l'avance, non aléatoire ainsi qu'homogène quel que soit le point d'écoute, que l'on soit assis devant le bureau, l'écran ou le meuble concerné, debout à faible distance de ceux-ci ou au contraire à distance éloignée. Par ailleurs, la réflexion latérale des mêmes fréquences médium et aigues sur les parois verticales concernées permettra d'améliorer dans la plupart des cas l'effet stéréophonique obtenu. L'ensemble, enfin, qui est de conception simple facile à utiliser, ne nécessite aucun réglage ni calibrage particulier.The advantages thus obtained are multiple: in a single, monobloc system, the possibility of broadcasting a sound whose rendering will be perfectly calibrated in advance, non-random as well as homogeneous whatever the point of listening, is available. whether one is sitting in front of the desk, the screen or the piece of furniture concerned, standing a short distance from them or, on the other hand, far away. Moreover, the lateral reflection of the same medium and high frequencies on the vertical walls concerned will make it possible to improve in most cases the stereophonic effect obtained. The assembly, finally, which is simple in design easy to use, requires no adjustment or special calibration.

Des variantes de cette configuration, non représentées dans les Figures 1 et 2, pourront être envisagées. Soit, afin d'élargir la bande passante en disposant vers l'arrière des tweeters à coté des haut-parleurs (3), également orientés vers le haut ou selon un angle réglable, ou aussi éventuellement selon un angle d'inclinaison différent de celui desdits haut-parleurs de médium (3). Par ailleurs, afin de permettre une adaptation plus pointue du système au type de surface murale ainsi que du degré d'absorption du local d'écoute, on pourra disposer des réglages électroniques permettant d'atténuer ou de configurer l'intensité du signal sonore ainsi que la courbe de réponse du système et desdits haut-parleurs (3). Des systèmes de remise en phase des zones de haut-parleurs avant (de façade) (2) et arrière (3) pourront, enfin, être disposés en fonction des différentes configurations d'écoute possibles.Variations of this configuration, not shown in the Figures 1 and 2 , may be considered. Either, in order to widen the bandwidth by arranging tweeters to the rear of the speakers (3), also oriented upwards or at an adjustable angle, or possibly also at a different inclination angle from that said midrange speakers (3). Moreover, in order to allow a more precise adaptation of the system to the type of wall surface and the degree of absorption of the listening room, it will be possible to have electronic adjustments for attenuating or configuring the intensity of the sound signal and than the response curve of the system and said loudspeakers (3). Re-phase systems of the front (front) (2) and rear (3) loudspeaker zones may finally be arranged according to the different possible listening configurations.

Un décalage des haut-parleurs arrière (3) par rapport aux haut-parleurs avant (2), ces derniers étant en retrait vers le centre du meuble alors que les haut-parleurs arrière (3) seraient placés davantage vers l'extérieur permettra par ailleurs dans certaines conditions de privilégier une écoute du meuble à plus grande distance de celui-ci en augmentant à ce niveau l'effet stéréophonique.An offset of the rear speakers (3) from the front speakers (2), the latter being recessed towards the center of the cabinet while the rear loudspeakers (3) are placed more outwards, will allow for elsewhere in certain conditions to favor a listening of the furniture to greater distance of this one by increasing at this level the stereophonic effect.

Dans les Figures 1 et 2, afin d'obtenir un effet de réflexion optimal, le dispositif selon l'invention est placé préférentiellement à proximité de, ou avantageusement contre, un mur standard, ou une paroi verticale (8).In the Figures 1 and 2 , in order to obtain an optimal reflection effect, the device according to the invention is preferably placed close to, or advantageously against, a standard wall, or a vertical wall (8).

Selon un mode particulier de réalisation de l'invention, ladite paroi verticale consiste en un écran (8'), par exemple un écran LCD, de télévision, sonore ou d'ordinateur ; c'est ce qui est illustré à la Figure 3 ou à la Figure 4.According to a particular embodiment of the invention, said vertical wall consists of a screen (8 '), for example an LCD, television, sound or computer screen; this is illustrated in the Figure 3 or at Figure 4 .

Dans la Figure 3, les haut-parleurs arrière (3) présentent comme précédemment un angle par rapport au plan horizontal, entre 25 et 70°, de telle sorte que le son qui en émane se réfléchisse contre l'écran (8').In the Figure 3 , the rear loudspeakers (3) have as previously an angle relative to the horizontal plane, between 25 and 70 °, so that the sound that emanates reflects against the screen (8 ').

La Figure 4 présente une variante de réalisation du dispositif illustré à la Figure 3 ; dans le but de gagner de la place, réduisant ainsi la profondeur de l'ensemble monobloc (1), les haut-parleurs avant (2) sont placés sous les haut-parleurs arrière (3), alors que dans les Figures 1 à 3, les haut-parleurs avant (2) et arrière (3) se situent sensiblement au même niveau.The Figure 4 presents an alternative embodiment of the device illustrated in FIG. Figure 3 ; in order to save space, thus reducing the depth of the monoblock assembly (1), the front speakers (2) are placed under the rear speakers (3), while in the Figures 1 to 3 , the front (2) and rear (3) speakers are at approximately the same level.
