Definitions
- the invention relates to the field of sound diffusion and is more particularly related to an acoustic device comprising one or more speakers and / or a subwoofer.
- Acoustic devices which comprise in particular a subwoofer.
- This box usually contains a speaker and associated electronics. These different components must occupy a relatively small space because the volume of free air in the box determines the performance of the latter. This requires having a box of relatively large dimensions relative to its content.
- the acoustic device further usually includes auxiliary speakers, a power supply and audio linkages.
- the invention aims to optimize the size of an acoustic device, in particular to facilitate its transport.
- an acoustic device comprising at least one box divided into at least one so-called “technical” compartment containing at least one loudspeaker, and a secondary compartment separated from the technical compartment by at least one acoustically transparent wall.
- the secondary compartment is arranged to be able to store at least one accessory, and is provided with an opening and means for closing said opening so that the secondary compartment, when empty, is acoustically useful, characterized in that the acoustically transparent wall has at least one curtain acoustically transparent and a game of baffles.
- the storage of at least one accessory in the secondary compartment when not used for acoustic purposes, therefore reduces the overall size of the acoustic device and facilitate its transport by limiting the number of separate elements to carry.
- the acoustically transparent wall opposes the introduction into the compartment of external elements - dirt, particles - while the secondary compartment is open.
- the closure means of the opening comprise a cover and means for clamping said cover relative to the secondary compartment.
- the box can selectively adopt two distinct configurations: one in which the technical compartment and the secondary compartment are attached to each other to cooperate acoustically and another in which the technical compartment and the compartment secondary are detached from each other.
- the secondary compartment is arranged so that the technical compartment closes the opening of the secondary compartment.
- the auxiliary loudspeaker is provided with a wireless receiver and cooperates with a wireless transmitter disposed in the technical compartment.
- the box is provided with a vent 50 in the form of a passage through the box 2, one end 51 is in the technical part 20 and the other end 52 is open on the outside of the box.
- This vent 50 is typical of the so-called "bass-reflex" subwoofers, that is to say which recover the sound waves emitted inside the box to restore them in phase with the sound emitted at the front of the box in the frequency range around the resonance frequency of the bass-reflex system. Note that in operation, since the two compartments 20 and 30 must form a sealed enclosure, the air must pass through no path other than that defined by the vent.
- the secondary compartment 30 is arranged to serve, when it does not cooperate acoustically with the technical compartment 20, storage area for accessories generally designated 10.
- These accessories 10 are here auxiliary acoustic speakers 11, a power supply 12 arranged for cooperate with the power source 23, and audio linkage elements 13 to cooperate with the auxiliary loudspeakers 11 or other additional acoustic device.
- the auxiliary loudspeakers 11 form right and left satellites of a 2.1 audio system.
- the auxiliary loudspeakers 11 may be wireless and then include a wireless receiver 14 cooperating with a wireless transmitter 24 disposed in the technical compartment 20, thereby making unnecessary the use of dedicated audio link elements.
- the box comprises an opening 31, shown in dotted line, for accessing the interior of the secondary compartment 30 and to deposit or remove the accessories.
- closure means 32 consist of a cover 32.1 cooperating with clamping means 32.2, here a single screw 32.5 through the cover 32.1 through a hole 32.4 and screwing into a dedicated thread 33 of the secondary compartment 30. Since the closure must be sealed, a seal 32.3 is used between the cover 32.1 and an outer face 34 of the compartment 30.
- the box further comprises an acoustically transparent wall (visually transparent or not) referenced 3 allowing both acoustic cooperation between the technical compartment 20 and the secondary compartment 30, letting the sound waves pass substantially as if there were no wall, when the device 1 is in operation, and to prevent the passage of any dust in the technical compartment 20 or just access in the technical compartment by a user when the secondary compartment is open.
- an acoustically transparent wall visually transparent or not referenced 3 allowing both acoustic cooperation between the technical compartment 20 and the secondary compartment 30, letting the sound waves pass substantially as if there were no wall, when the device 1 is in operation, and to prevent the passage of any dust in the technical compartment 20 or just access in the technical compartment by a user when the secondary compartment is open.
- the acoustically transparent wall 3 allows the acoustic cooperation between the technical compartment 20 and the secondary compartment 30 by allowing the passage from one to the other of an air flow F, but also prevents the passage of any dust P.
- it may comprise at least one acoustically transparent curtain 4 fixed on one side 25 of the technical compartment 20 in addition to a set of baffles 5 disposed in the technical compartment 20. This set of baffles 5 must be arranged so as to let a sufficient air flow F so that the assembly is acoustically transparent.
- This acoustically transparent wall 3 can adopt different configurations.
- the acoustically transparent wall 3 may, in a variant that does not fall within the scope of the invention, include the same acoustically transparent curtain 4 but this time in addition to a grid 6 replacing the wall 25 of the technical compartment 20 and making it unnecessary to use a baffle game.
- the grid 6 can be acoustically transparent only if the orifices constituting it represent at least 50% of its total surface area.
- the technical and secondary compartments 30 can be detached from one another, forming a box 2 'in two parts, the junction zone being at the level of the acoustically wall transparent 3 of the technical compartment 20 always so that the interior of said technical compartment 20 remains protected from any dust.
- This detached configuration may be convenient, for example, for transport.
- the two compartments (20; 30) when the two compartments (20; 30) are attached, it is the technical compartment 20 that serves as a means of closing an opening 31 'of the secondary compartment 30 by which the accessory or accessories 10 are accessible and which therefore adopts a provision substantially different from that previously described.
- the two compartments (20; 30) forming the caisson 2 again can cooperate acoustically as soon as the acoustic device 1 is in operation.
- Assembling means (not visible in the figure) adapted to hold the two compartments together are used and comprise, for example, clamping and / or screwing means.
- a seal at the junction between the two compartments must be ensured.
- a joint will be considered between the faces in contact at the junction between the two compartments (20; 30).
- the vent 50 may be multiple or adopt a number of different arrangements and geometries depending on the desired acoustic response.
- a closed subwoofer that is to say without vent, is also possible according to the invention.
- sealing means means grouping any type of hatch, sliding or pivoting.
- the clamping means too can vary. In particular, we will consider the multiplication of screwing, the use of systems by clipping or magnetic closures.
- the acoustically transparent wall may adopt other shapes or configurations.
- the acoustically transparent curtain 4 and / or the set of baffles 5 and / or the grid 6 can be fixed on the side of the secondary compartment 30.
- the use of an acoustically transparent curtain alone is also possible as long as it allows a passage of sufficient airflow F and prevents that of the dust P and access in general inside the technical compartment 20.

Description
L'invention concerne le domaine de la diffusion sonore et est plus particulièrement relative à un dispositif acoustique comportant une ou plusieurs enceintes et/ou un caisson de basses.The invention relates to the field of sound diffusion and is more particularly related to an acoustic device comprising one or more speakers and / or a subwoofer.
On connaît des dispositifs acoustiques comportant notamment un caisson de basses. Ce caisson contient généralement un haut-parleur et une électronique associée. Ces différents composants doivent occuper un encombrement relativement faible car le volume d'air libre dans le caisson conditionne les performances de ce dernier. Ceci impose d'avoir un caisson de dimensions relativement importantes par rapport à son contenu.Acoustic devices are known which comprise in particular a subwoofer. This box usually contains a speaker and associated electronics. These different components must occupy a relatively small space because the volume of free air in the box determines the performance of the latter. This requires having a box of relatively large dimensions relative to its content.
Le dispositif acoustique comporte en outre habituellement des enceintes auxiliaires, un bloc d'alimentation et des éléments de liaison audio.The acoustic device further usually includes auxiliary speakers, a power supply and audio linkages.
Pour résumer, un tel dispositif acoustique est encombrant et son transport malcommode.To summarize, such an acoustic device is bulky and inconvenient transport.

L'invention a pour but l'optimisation de l'encombrement d'un dispositif acoustique, notamment pour faciliter son transport.The invention aims to optimize the size of an acoustic device, in particular to facilitate its transport.
A cet effet, on propose, selon l'invention, un dispositif acoustique comportant au moins un caisson divisé en au moins un compartiment dit « technique » contenant au moins un haut-parleur, et un compartiment secondaire séparé du compartiment technique par au moins une paroi acoustiquement transparente. Le compartiment secondaire est agencé pour pouvoir stocker au moins un accessoire, et est pourvu d'une ouverture ainsi que des moyens d'obturation de ladite ouverture pour que le compartiment secondaire, lorsqu'il est vide, soit acoustiquement utile, caractérisé en ce que la paroi acoustiquement transparente comporte au moins un voilage acoustiquement transparent et un jeu de chicanes. Le stockage d'au moins un accessoire dans le compartiment secondaire, lorsqu'il n'est pas utilisé à but acoustique, permet donc de diminuer l'encombrement général du dispositif acoustique et de faciliter son transport en limitant le nombre d'éléments séparés à transporter. La paroi acoustiquement transparente s'oppose à l'introduction dans le compartiment d'éléments extérieurs - saletés, particules - pendant que le compartiment secondaire est ouvert.For this purpose, according to the invention, an acoustic device is proposed comprising at least one box divided into at least one so-called "technical" compartment containing at least one loudspeaker, and a secondary compartment separated from the technical compartment by at least one acoustically transparent wall. The secondary compartment is arranged to be able to store at least one accessory, and is provided with an opening and means for closing said opening so that the secondary compartment, when empty, is acoustically useful, characterized in that the acoustically transparent wall has at least one curtain acoustically transparent and a game of baffles. The storage of at least one accessory in the secondary compartment, when not used for acoustic purposes, therefore reduces the overall size of the acoustic device and facilitate its transport by limiting the number of separate elements to carry. The acoustically transparent wall opposes the introduction into the compartment of external elements - dirt, particles - while the secondary compartment is open.
De préférence, les moyens d'obturation de l'ouverture comportent un couvercle et des moyens de bridage dudit couvercle par rapport au compartiment secondaire.Preferably, the closure means of the opening comprise a cover and means for clamping said cover relative to the secondary compartment.
En variante ou en addition, le caisson peut sélectivement adopter deux configurations distinctes : l'une dans laquelle le compartiment technique et le compartiment secondaire sont attachés l'un à l'autre pour coopérer acoustiquement et une autre dans laquelle le compartiment technique et le compartiment secondaire sont détachés l'un de l'autre.Alternatively or in addition, the box can selectively adopt two distinct configurations: one in which the technical compartment and the secondary compartment are attached to each other to cooperate acoustically and another in which the technical compartment and the compartment secondary are detached from each other.
Avantageusement alors, le compartiment secondaire est agencé de manière que le compartiment technique obture l'ouverture du compartiment secondaire.Advantageously then, the secondary compartment is arranged so that the technical compartment closes the opening of the secondary compartment.
De préférence, ledit au moins accessoire comprend au moins un élément du groupe d'éléments suivant :
- une enceinte acoustique auxiliaire ;
- un bloc d'alimentation électrique ;
- un élément de liaison audio.
- an auxiliary loudspeaker;
- a power supply unit;
- an audio link element.
En variante, l'enceinte acoustique auxiliaire est pourvue d'un récepteur sans fil et coopère avec un émetteur sans fil disposé dans le compartiment technique.Alternatively, the auxiliary loudspeaker is provided with a wireless receiver and cooperates with a wireless transmitter disposed in the technical compartment.
L'invention sera mieux comprise à la lecture de la description qui suit d'un mode de réalisation particulier non limitatif de l'invention.The invention will be better understood on reading the following description of a particular non-limiting embodiment of the invention.

- un compartiment dit « technique » 20 contenant un haut-
parleur 21, des composants électroniques 22 associés et un organe d'alimentation 23, - un compartiment secondaire 30 qui lorsqu'il est vide, est acoustiquement utile, c'est-à-dire qu'il forme avec le compartiment technique 20 une enceinte étanche à l'air et coopère donc acoustiquement avec ledit compartiment technique, lorsque le dispositif acoustique 1 est en fonctionnement. Ceci veut dire notamment que le volume du compartiment secondaire est déterminé en fonction des performances acoustiques souhaitées pour le caisson.
- a so-called "technical"
compartment 20 containing aloudspeaker 21, associatedelectronic components 22 and apower supply member 23, - a
secondary compartment 30 which when empty is acoustically useful, that is to say that it forms with thetechnical compartment 20 an airtight enclosure and therefore cooperates acoustically with said technical compartment, when the device acoustic 1 is in operation. This means in particular that the volume of the secondary compartment is determined according to the desired acoustic performance for the box.
Le caisson est pourvu d'un évent 50, sous forme d'un passage traversant le caisson 2, dont une extrémité 51 se trouve dans la partie technique 20 et dont l'autre extrémité 52 est ouverte sur l'extérieur du caisson. Cet évent 50 est typique des caissons de basses dits « bass-reflex », c'est-à-dire qui récupèrent les ondes sonores émises à l'intérieur du caisson pour les restituer en phase avec le son émis à l'avant du caisson dans la gamme de fréquence autour de la fréquence de résonance du système bass-reflex. On notera qu'en fonctionnement, étant donné que les deux compartiments 20 et 30 doivent former une enceinte étanche, l'air ne doit passer par aucun autre chemin que celui défini par l'évent.The box is provided with a
Selon l'invention, le compartiment secondaire 30 est agencé pour servir, lorsqu'il ne coopère pas acoustiquement avec le compartiment technique 20, de zone de stockage pour des accessoires généralement désignés en 10. Ces accessoires 10 sont ici des enceintes acoustiques auxiliaires 11, un bloc d'alimentation 12 agencé pour coopérer avec la source d'alimentation 23, et des éléments de liaison audio 13 pour coopérer avec les enceintes acoustiques auxiliaires 11 ou tout autre dispositif acoustique supplémentaire. Les enceintes acoustiques auxiliaires 11 forment des satellites droit et gauche d'un système audio 2.1. On notera que les enceintes acoustiques auxiliaires 11 peuvent être sans fil et alors comporter un récepteur sans fil 14 coopérant avec un émetteur sans fil 24 disposé dans le compartiment technique 20, rendant de ce fait inutile l'utilisation d'éléments de liaison audio dédiés.According to the invention, the
Le caisson comprend une ouverture 31, représentée en pointillée, permettant d'accéder à l'intérieur du compartiment secondaire 30 et d'y déposer ou d'en retirer les accessoires.The box comprises an
L'ouverture 31 doit pouvoir être obturée de manière étanche pour que le compartiment secondaire 30 soit acoustiquement utile lorsqu'il est vide. A cet effet, on utilise des moyens d'obturation 32 constitués d'un couvercle 32.1 coopérant avec des moyens de bridage 32.2, ici une simple vis 32.5 traversant le couvercle 32.1 par un trou 32.4 et se vissant dans un taraudage dédié 33 du compartiment secondaire 30. L'obturation devant être étanche, on utilise un joint 32.3 disposé entre le couvercle 32.1 et une face externe 34 du compartiment 30.The opening 31 must be sealable so that the
Le caisson comprend en outre une paroi acoustiquement transparente (visuellement transparente ou non) référencée 3 permettant à la fois une coopération acoustique entre le compartiment technique 20 et le compartiment secondaire 30, en laissant passer les ondes sonores sensiblement comme s'il n'y avait pas de paroi, lorsque le dispositif 1 est en fonctionnement, et d'empêcher le passage d'éventuelles poussières dans le compartiment technique 20 ou tout simplement l'accès audit compartiment technique par un utilisateur lorsque le compartiment secondaire est ouvert.The box further comprises an acoustically transparent wall (visually transparent or not) referenced 3 allowing both acoustic cooperation between the

Avantageusement alors, lorsque les deux compartiments (20; 30) sont attachés, c'est le compartiment technique 20 qui sert de moyen d'obturation d'une ouverture 31' du compartiment secondaire 30 par laquelle le ou les accessoires 10 sont accessibles et qui adopte donc une disposition sensiblement différente de celle précédemment décrite. Ainsi, lorsque le compartiment secondaire 30 est vide et qu'il est attaché au compartiment technique 20, les deux compartiments (20 ; 30) formant de nouveau le caisson 2 peuvent coopérer acoustiquement dès que le dispositif acoustique 1 est en fonctionnement. Des moyens d'assemblage (non-visibles sur la figure) adaptés pour maintenir assemblés les deux compartiments sont utilisés et comprennent par exemple des moyens de bridage et/ou de vissage. Bien sûr, une étanchéité au niveau de la jonction entre les deux compartiments doit être assurée. On pensera notamment à un joint disposé entre les faces en contact à la jonction entre les deux compartiments (20 ; 30).Advantageously then, when the two compartments (20; 30) are attached, it is the
Bien entendu, l'invention n'est pas limitée aux modes de réalisation décrits mais englobe toute variante entrant dans le champ de l'invention telle que définie par les revendications.Of course, the invention is not limited to the embodiments described but encompasses any variant within the scope of the invention as defined by the claims.
L'évent 50 peut être multiple ou adopter nombre de dispositions et géométries différentes en fonction de la réponse acoustique souhaitée.The
En variante, un caisson de basses clos, c'est-à-dire sans évent, est également possible selon l'invention.Alternatively, a closed subwoofer, that is to say without vent, is also possible according to the invention.
D'autres moyens d'obturation peuvent être utilisés, moyens regroupant n'importe quel type de trappe, coulissante ou pivotante. Les moyens de bridage eux aussi peuvent varier. On pensera notamment à la multiplication des vissages, à l'utilisation de systèmes par clipage ou de fermetures magnétiques.Other sealing means may be used, means grouping any type of hatch, sliding or pivoting. The clamping means too can vary. In particular, we will consider the multiplication of screwing, the use of systems by clipping or magnetic closures.
La paroi acoustiquement transparente peut adopter d'autres formes ou configurations. Notamment, le voilage acoustiquement transparent 4 et/ou le jeu de chicanes 5 et/ou la grille 6 peuvent être fixés du côté du compartiment secondaire 30. Il ne fait aucun doute que dans une variante qui n'entre pas dans le champ de l'invention, l'utilisation d'un voilage acoustiquement transparent seul est lui aussi possible tant que ce dernier permet un passage de flux d'air F suffisant et empêche celui de la poussière P ainsi que l'accès en général à l'intérieur du compartiment technique 20.The acoustically transparent wall may adopt other shapes or configurations. In particular, the acoustically
De même, on peut utiliser avec le voilage acoustiquement transparent 4, à la fois la grille 6 et le jeu de chicanes 5.Similarly, it is possible to use, with the acoustically
