Abstract

The process involves modifying a standard plastic box shaped container (1) of the type used to hold liquids, with an upper carrying handle (2). To hold the loudspeaker, a circular hole (4) is made in the front face of the container, and internal electrics, such as the battery and amplifier inserted, followed by the loudspeaker (5) in the front hole. A container with a ribbed front (8) is preferred for modification, as this allows free air passage to the container inside.

Description

La présente invention est relative à un procédé de fabrication d'une enceinte acoustique et, plus particulièrement, d'une enceinte acoustique portable. The present invention relates to a method for manufacturing an acoustic enclosure and, more particularly, a portable acoustic enclosure.

Dans tout ce qui va suivre l'expression "enceinte acoustique" comprendra tout ensemble comportant, au moins, un haut-parleur disposé dans un boîtier. In all that follows the expression "acoustic enclosure" will include any assembly comprising, at least, a loudspeaker arranged in a housing.

Dans la pratique, une enceinte acoustique comporte un boîtier rigide, métallique ou en bois et, si elle est portable, une poignée. In practice, an acoustic enclosure comprises a rigid, metallic or wooden case and, if it is portable, a handle.

L'expérience a montré que le boîtier, muni de sa poignée, constituait, au niveau du prix de revient de l'ensemble, un poste bien supérieur à celui consacré aux éléments électriques et électroniques. II est apparu aussi que ce poste était difficilement compressible selon les techniques actuelles. Experience has shown that the case, provided with its handle, constitutes, at the cost price of the assembly, a position much higher than that devoted to electrical and electronic elements. It also appeared that this station was difficult to compress using current techniques.

A cela s'ajoute le fait que le boîtier, de par sa conception, est lourd et difficilement portable pour des enceintes puissantes. Added to this is the fact that the housing, by design, is heavy and difficult to portable for powerful speakers.

L'ensemble des raisons ci-dessus a conduit les fabricants à concevoir des enceintes de faible puissance et très peu sophistiquées pour gagner tant sur le poids que sur le prix de revient. All of the above reasons have led manufacturers to design low-power and very unsophisticated loudspeakers to save both weight and cost.

Le procédé de l'invention, qui remédie à ces inconvénients, consiste à utiliser, pour réaliser le boîtier de l'enceinte, un conteneur prismatique en matière plastique du commerce tels que ceux utilisés pour le transport des liquides. The method of the invention, which overcomes these drawbacks, consists in using, to produce the enclosure of the enclosure, a prismatic container made of commercial plastic material such as those used for transporting liquids.

Outre le fait que le prix de revient d'un tel conteneur est extrêmement bas, les frais relatifs à sa transformation pour le rendre apte à sa nouvelle fonction sont quasiment nuls, le seul usinage important consistant à découper sur l'une de ses faces latérales une ouverture pour placer le haut-parleur. In addition to the fact that the cost price of such a container is extremely low, the costs relating to its transformation to make it suitable for its new function are almost zero, the only important machining consisting in cutting on one of its lateral faces. an opening to place the speaker.

II est à noter que l'ouverture précitée permet d'accéder facilement à l'intérieur pour permettre la fixation des différents interrupteurs ou connecteurs et la mise en place d'organes divers conférant à l'enceinte des caractéristiques élevées. It should be noted that the aforementioned opening allows easy access to the interior to allow the fixing of the various switches or connectors and the installation of various members giving the enclosure high characteristics.

La présente invention sera mieux comprise par la description qui va suivre faite en se référant au dessin annexé à titre d'exemple indicatif, seulement sur lequel
-la figure 1 est une vue en élévation d'un conteneur du commerce;
-la figure 2 est, à plus grande échelle, une vue en coupe effectuée selon la ligne Il-Il de la figure 1 montrant une enceinte réalisée selon le procédé de l'invention.
The present invention will be better understood from the description which follows, given with reference to the attached drawing by way of indicative example, only on which
FIG. 1 is an elevation view of a commercial container;
FIG. 2 is, on a larger scale, a sectional view taken along line II-II of FIG. 1 showing an enclosure produced according to the method of the invention.

En se reportant au dessin, on voit que le procédé de l'invention consiste à utiliser un conteneur 1, comportant une poignée 2 et un bouchon usuel 3. La forme générale du conteneur 1 est celle des jerricanes utilisés pour le transport des carburants, mais d'autres conteneurs de forme prismatique peuvent être utilisés. Referring to the drawing, it can be seen that the method of the invention consists in using a container 1, comprising a handle 2 and a usual plug 3. The general shape of the container 1 is that of the jerry cans used for transporting fuels, but other prismatic containers can be used.

De préférence, le conteneur 1 est du genre de ceux réalisés en une matière plastique moulée, élastiquement déformable. Preferably, the container 1 is of the kind made of a molded plastic material, elastically deformable.

Pour transformer le conteneur 1, il suffit de découper sur l'une de ses faces 1 a une ouverture circulaire 4 permettant l'introduction d'un haut-parleur usuel 5 dont la collerette 6 prend appui et est fixée contre ladite face la, par exemple à l'aide de vis non représentées. To transform the container 1, it suffices to cut on one of its faces 1 has a circular opening 4 allowing the introduction of a conventional loudspeaker 5 whose flange 6 is supported and is fixed against said face 1a, by example using screws not shown.

Préalablement à la fixation du haut-parleur, on procède à la mise en place des interrupteurs et des connecteurs nécessaires au fonctionnement de l'enceinte. Ceux-ci sont d'un type usuel, peuvent être placés en tout endroit sans poser de problème et, par conséquent, n'ont pas été représentés. Before fixing the loudspeaker, the switches and connectors necessary for the operation of the enclosure are installed. These are of the usual type, can be placed anywhere without causing problems and, therefore, have not been shown.

De même, on procède à la mise en place de la source d'énergie autonome 7, éventuellement à celle d'un amplificateur (non représenté) et on effectue les raccordements électriques internes.  Likewise, the autonomous power source 7 is put in place, possibly that of an amplifier (not shown) and internal electrical connections are made.

Compte tenu que le boîtier de l'enceinte est très léger, la source d'énergie autonome 7 peut être constituée par une batterie rechargeable qui confère à l'enceinte une autonomie bien supérieure à celle obtenue avec les piles placées dans les enceintes connues à ce jour. Given that the enclosure of the enclosure is very light, the autonomous energy source 7 can be constituted by a rechargeable battery which gives the enclosure an autonomy much greater than that obtained with the batteries placed in the enclosures known to this day.

II est à noter que par le procédé de l'invention il est possible, tout en restant inférieur aux enceintes existantes tant en ce qui concerne le prix de revient que le poids, d'utiliser plusieurs hautparleurs, un sur chacune des faces du boîtier et, ainsi, de diffuser les sons, pratiquement, tout autour de l'enceinte, ce qui confère à ladite enceinte une caractéristique très importante lorsque cette dernière est utilisée lors d'un spectacle de rue par exemple. It should be noted that by the method of the invention it is possible, while remaining lower than the existing enclosures both with regard to the cost price and the weight, to use several speakers, one on each of the faces of the housing and , thus, to diffuse the sounds, practically, all around the enclosure, which gives said enclosure a very important characteristic when the latter is used during a street performance for example.

Comme on le sait, les enceintes acoustiques doivent présenter des évents pour permettre à l'air, contenu dans celles-ci et comprimé sous l'effet des vibrations, de sortir et d'entrer librement. As is known, the loudspeakers must have vents to allow the air, contained in them and compressed under the effect of vibrations, to exit and enter freely.

La réalisation de tels évents sur des enceintes connues nécessite des usinages qui augmentent le prix de revient du boîtier. The production of such vents on known enclosures requires machining operations which increase the cost price of the housing.

Selon l'invention, on utilise l'orifice de vidange usuel du conteneur pour constituer l'évent. II suffit pour cela de dévisser le bouchon 3. Sur certains conteneurs, il est prévu une prise d'air pour faciliter leur remplissage et leur vidange. Cette prise d'air peut aussi être utilisée à cet effet. According to the invention, the usual emptying orifice of the container is used to constitute the vent. It suffices to unscrew the cap 3. For some containers, there is an air intake to facilitate their filling and emptying. This air intake can also be used for this purpose.

Comme cela ressort de la figure 1, certains conteneurs sont pourvus de nervures de raidissement, celles-ci, venues de moulage se présentant, vues de l'extérieur sous la forme de rainures 8. As can be seen in FIG. 1, some containers are provided with stiffening ribs, these, coming from molding occurring, seen from the outside in the form of grooves 8.

Selon l'invention, ces rainures sont utilisées pour former, en combinaison avec la collerette du haut-parleur, les évents précités. Pour cela, il suffit que l'ouverture 4 coupe transversalement l'une des rainures 8 (fiv.1).  According to the invention, these grooves are used to form, in combination with the collar of the loudspeaker, the aforementioned vents. For this, it suffices that the opening 4 transversely cuts one of the grooves 8 (fiv.1).
