Description

La présente invention concerne un haut parleur destiné à être immergé dans l'eau de manière à y propager des sons.The present invention relates to a loudspeaker intended to be immersed in water so as to propagate sounds.

Dans ce domaine des haut parleurs sous-marins ont déjà été proposés en utilisant comme élément de diffusion du son, le quartz.In this field of underwater speakers have already been proposed using as a sound diffusion element, quartz.

Pour des problèmes d'étanchéité que l'on peut imaginer, les haut parleurs à membrane avaient toujours été exclus pour diffuser des sons dans l'eau, alors que le quartz présentait l'avantage de pouvoir être enrobé d'une matière plastique isolante, apportant certes les caractéristiques d'étanchéité recherchées, mais offrant en contrepartie une très mauvaise qualité de son.For sealing problems that can be imagined, the diaphragm loudspeakers had always been excluded to broadcast sounds in the water, while the quartz had the advantage of being able to be coated with an insulating plastic material, While providing the desired sealing characteristics, but offering in return a very poor sound quality.

En fait, les haut parleurs sous-marins à quartz ne restituent pas la bande passante en dessous de 400 Hz, c'est-à-dire les graves et les bas médiums. L'écoute de la musique dans l'eau étant extrêmement sensible, de nature psycho-sensorielle, fait qu'un signal vibro-tactile inexact est refusé et la réaction de tout individu est de sortir de l'eau.In fact, the quartz underwater speakers do not restore the bandwidth below 400 Hz, that is to say the low and low mediums. Listening to music in the water is extremely sensitive, of psycho-sensory nature, makes an inaccurate vibro-tactile signal is refused and the reaction of any individual is to get out of the water.

Ce type de haut parleur aquatique a déjà trouvé une application sportive dans la natation synchronisée puis, dans le but de se relaxer, il a été imaginé de transposer cette technique aux piscines, jacuzzis, baignoires, mais le problème restait entier et il était considéré que la voix parlée et une musique de qualité ne pouvaient être diffusées et entendues sous l'eau.This type of water speaker has already found a sporting application in synchronized swimming and, in order to relax, it was imagined to transfer this technique to swimming pools, Jacuzzis, bathtubs, but the problem remained whole and it was considered that the spoken voice and quality music could not be broadcast and heard underwater.

Selon une première phase de la démarche inventive, ce préjugé a été vaincu en estimant que la voix parlée et la musique de qualité pouvaient parfaitement être diffusées et entendues sous l'eau à condition d'utiliser une membrane.According to a first step of the inventive step, this prejudice was overcome by considering that the spoken voice and the quality music could be perfectly diffused and heard under the water provided to use a membrane.

Bien entendu, les membranes traditionnelles qui sont en carton tropicalisé supportant certes l'hygrométrie mais qui n'est en aucun cas immergeable, ne pouvaient être envisagées.Of course, the traditional membranes which are tropicalized cardboard certainly supporting the humidity but which is by no means immersible, could not be envisaged.

C'est en voulant vaincre ce second préjugé que l'invention a été réalisée, mais la solution devait consister à offrir premièrement une qualité acoustique haute fidélité, c'est-à-dire restituant la bande passante de la fréquence musicale en dessous de 400 Hz à savoir graves et bas médiums, et deuxièmement une étanchéité parfaite.It is by trying to overcome this second prejudice that the invention was made, but the solution was to offer firstly a high fidelity acoustic quality, that is to say, restoring the bandwidth of the musical frequency below 400 Hz namely serious and low midrange, and secondly a perfect seal.

FR 2633480 décrit un haut-parleur aquatique ayant une membrane circulaire en matière plastique, une chambre interne étanche et une coque en forme de cloche. EP 1063632 décrit un haut-parleur aquatique ayant une chambre étanche, un rebord périphérique et dont le montage de la membrane est obtenu par moulage.

La figure 4 est une vue en perspective, partiellement en coupe, d'un ensemble de haut parleur selon la figure 3, avec une enveloppe extérieure, selon un second mode de réalisation.The figure 4 is a perspective view, partly in section, of a loudspeaker assembly according to the figure 3 with an outer casing, according to a second embodiment.

La figure 5 est une vue latérale schématique d'un haut parleur muni d'une enveloppe selon le mode de réalisation de la figure 4.The figure 5 is a schematic side view of a loudspeaker provided with an envelope according to the embodiment of the figure 4 .

La figure 6 est une vue de dessus d'un haut parleur selon la figure 5.The figure 6 is a top view of a speaker according to the figure 5 .

Un haut parleur est traditionnellement constitué par un élément 2 de diffusion du son qui est associé à une bobine 3 se composant d'un support isolant 4 et d'un bobinage électrique 5, elle-même en liaison avec un aimant périphérique 6, de manière à obtenir la transformation d'une tension électrique en une fréquence musicale.A loudspeaker is traditionally constituted by a sound diffusion element 2 which is associated with a coil 3 consisting of an insulating support 4 and an electric winding 5, itself in connection with a peripheral magnet 6, so that to obtain the transformation of an electrical voltage into a musical frequency.

Selon l'invention, l'élément 2 de diffusion du son est une membrane 2 constituée par une paroi plane circulaire en matière plastique, d'épaisseur prédéterminée, apte à produire le son en association avec la bobine 3 et avec une coque 7 en forme de cloche, également en matière plastique, associée d'une part à la membrane 2 par son bord périphérique inférieur ouvert 8, et d'autre part à l'aimant 6 se logeant au moins partiellement dans une ouverture correspondante 9 ménagée sur le dos 7a de la coque 7, ces éléments constituant un ensemble définissant entre eux une chambre interne étanche 10 à l'intérieur de laquelle est disposée la bobine électrique 3 en liaison étroite avec la membrane 2 et avec l'aimant 6.According to the invention, the sound diffusion element 2 is a membrane 2 constituted by a circular flat wall made of plastic, of predetermined thickness, capable of producing the sound in association with the coil 3 and with a shell 7 in the form of bell, also made of plastic, associated on the one hand with the membrane 2 by its open lower peripheral edge 8, and on the other hand with the magnet 6 accommodating at least partially in a corresponding opening 9 formed on the back 7a of the shell 7, these elements constituting an assembly defining between them an internal sealed chamber 10 inside which is disposed the electric coil 3 in close connection with the membrane 2 and with the magnet 6.

Comme le montrent bien les figures 1 ou 4, selon des modes de réalisation différents, l'ensemble étanche constitué par la membrane 2, la coque 7 et l'aimant 6 comporte dans sa partie dorsale 7a, opposée à la membrane 2, une enveloppe 11, 12 assurant une étanchéité supplémentaire et dont la forme est telle à permettre l'obtention d'une directivité optimum du son.As the figures 1 or 4 , according to different embodiments, the sealed assembly constituted by the membrane 2, the shell 7 and the magnet 6 comprises in its dorsal portion 7a, opposite the membrane 2, an envelope 11, 12 providing additional sealing and whose shape is such as to obtain an optimum directivity of the sound.

Plus particulièrement, selon l'exemple de réalisation des figures 1 et 2, l'enveloppe externe 11 est obtenue par un surmoulage de forme globalement cylindrique ou en forme d'ampoule électrique et comporte des moyens de fixation 13 disposés de manière telle à permettre le montage dudit haut parleur en lieu et place d'un projecteur de lumière subaquatique, en remplacement de son ampoule.More particularly, according to the exemplary embodiment of Figures 1 and 2 the outer casing 11 is obtained by overmoulding of generally cylindrical shape or in the form of an electric bulb and comprises fastening means 13 arranged so as to allow the mounting of said speaker instead of a light projector underwater, replacing his bulb.

Selon le second exemple de réalisation représenté sur les figures 4, 5 et 6, l'enveloppe externe 12 est obtenue par un surmoulage en forme de coquille saint jacques, pour présenter un plan d'ouverture P dans lequel est apte à s'inscrire la membrane plane 2, tout en autorisant un surmoulage d'épaisseur variable, faible e vers l'avant, relativement plus épais E vers l'arrière, de façon à obtenir une directivité optimum du son.According to the second exemplary embodiment shown figures 4 , 5 and 6 , the outer casing 12 is obtained by overmoulding in the shape of scallop shells, to present an aperture plane P in which is able to register the plane membrane 2, while allowing overmoulding of variable thickness, low e forward, relatively thicker E backwards, so as to obtain optimum directivity of the sound.

Selon une autre caractéristique de l'invention, particulièrement bien visible sur la figure 3, la coque 7 est associée à la membrane 2, à proximité de leurs bords périfériques respectifs, par l'intermédiaire d'une lèvre périphérique externe 14 issue de la membrane 2 et obtenue avec celle-ci au cours d'une même opération de moulage d'une matière plastique, ladite lèvre 14 formant un taquet contre la paroi latérale périphérique interne duquel vient en appui par emboîtement la paroi latérale externe de son bord périphérique inférieur 8 de la coque 7.According to another characteristic of the invention, particularly clearly visible on the figure 3 , the shell 7 is associated with the membrane 2, near their respective perimeter edges, via an outer peripheral lip 14 coming from the membrane 2 and obtained with it during the same molding operation a plastic material, said lip 14 forming a cleat against the inner peripheral side wall of which abuts by pressing the outer side wall of its lower peripheral edge 8 of the shell 7.

Par ailleurs, la fixation externe et la retenue axiale de la membrane 2 par rapport à la coque 7 sont réalisées par l'intermédiaire d'un nombre prédéterminé de vis (non représentées) traversant dans une direction radiale le taquet périphérique 14 de la membrane 2 puis le bord périphérique inférieur 8 de la coque 7.Moreover, the external fixation and the axial retention of the membrane 2 with respect to the shell 7 are made by means of a predetermined number of screws (not shown) traversing in a radial direction the peripheral cleat 14 of the membrane 2 then the lower peripheral edge 8 of the shell 7.

De manière à parfaire l'étanchéité, la membrane 2 définit dans son plan P', au-delà de son taquet périphérique 14, un rebord 15, également périphérique, destiné à retenir un produit d'étanchéité lors de son application sur la zone périphérique inférieure de l'ensemble, constituée par le taquet 14, la base 8 de la coque 7 et les vis.In order to perfect the seal, the membrane 2 defines in its plane P ', beyond its peripheral cleat 14, a flange 15, also peripheral, intended to retain a sealant when it is applied to the peripheral zone bottom of the assembly, constituted by the cleat 14, the base 8 of the shell 7 and the screws.

Selon une autre caractéristique de l'invention, la membrane 2 comporte sur sa face interne une zone formant une cuvette 16 délimitée par deux lèvres concentriques, l'une interne 17 étant destinée à l'emboîtement par l'extérieur du support isolant 4 de la bobine 3, avec un serrage prédéfini, l'autre externe 18, définissant avec la première 17 la cuvette 16 destinée à constituer un réservoir de colle dans laquelle sera immergée l'extrémité périphérique du support: 4 de la bobine 3, celle-ci ayant également été enduite de colle, préalablement à son emboîtement, de manière à obtenir une liaison indissociable avec la membrane 2.According to another characteristic of the invention, the membrane 2 comprises on its inner face a zone forming a bowl 16 delimited by two concentric lips, the inner one 17 being intended for interlocking by the outside of the insulating support 4 of the coil 3, with a predefined clamping, the other external 18, defining with the first 17 the bowl 16 intended to form a glue tank in which the peripheral end of the support 4 of the coil 3, the latter being immersed, has also been coated with glue, prior to its nesting, so as to obtain an inseparable connection with the membrane 2.

Les essais ont démontré que d'excellents résultats ont été obtenus avec une membrane 2 en matière plastique, d'une épaisseur comprise entre 2 et 4 mm.The tests have shown that excellent results have been obtained with a membrane 2 made of plastic, having a thickness of between 2 and 4 mm.

En ce qui concerne les matières utilisées, la membrane 2 pourra être réalisée en un plastique polyuréthane armé fibres de verre, alors que la coque 7 pourra par exemple être réalisée en polypropylène chargé.Regarding the materials used, the membrane 2 may be made of a polyurethane plastic reinforced with glass fibers, while the shell 7 may for example be made of filled polypropylene.

L'enveloppe quant à elle est réalisée à partir d'une résine silicone.The envelope as for it is made from a silicone resin.

Ces différents matériaux sont insensibles à l'eau chlorée.These different materials are insensitive to chlorinated water.

Selon une variante de réalisation non représentée, la membrane 2 et la coque 7 sont obtenues de manière monobloc, au cours d'une même opération de moulage.According to an alternative embodiment not shown, the membrane 2 and the shell 7 are obtained in a single piece, during a single molding operation.
