Description

HAUT PARLEUR AQUATIQUE A MEMBRANE MEMBRANE AQUATIC SPEAKER
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 for being immersed in water so as to propagate sounds therein.
Dans ce domaine des haut parleurs sous-marins ont déj à été proposés en utilisant comme élément de diffusion du son, le quartz .In this area of the 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 touj ours 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. 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.For problems of watertightness that one could imagine, the membrane loudspeakers had always been excluded to diffuse sounds in the water, whereas the quartz had the advantage of being able to be wrapped in an insulating plastic material , while providing the desired sealing characteristics, but offering in return a very poor sound quality. In fact, the quartz underwater speakers do not reproduce the bandwidth below 400 Hz, that is to say the low and low mediums. Listening to music in the water is extremely sensitive, psycho - sensory in nature, that 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- appϋ-ea-tion- ^por-fei-ve- dans la- natatiûEL 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. 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 .This type of water loudspeaker has already found an appetizer for synchronized swimming and then, in order to relax, it has been imagined to transpose this technique to swimming pools, jacuzzis , baths, but the problem remained unresolved and it was considered that the spoken voice and quality music could not be broadcast and heard underwater. According to a first phase of the inventive step, this prejudice was overcome by considering that the spoken voice and the quality music could perfectly be 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 . 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 .Of course, the traditional membranes which are tropicalized cardboard certainly supporting the hygrometry but which is in no way immersible, could not be envisaged. It is in attempting to overcome this second prejudice that the invention was realized, but the solution had to consist in first offering 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.
A cet effet, l' invention concerne un haut parleur aquatique du type constitué par un élément de diffusion du son qui est associé à une bobine se composant d' un support isolant et d' un bobinage électrique, elle-même en liaison avec un aimant périphérique, de manière à obtenir la transformation d' une tension électrique en une fréquence musicale, caractérisé en ce que l' élément de diffusion du son est une membrane constituée par une paroi plane circulaire en matière plastique, d' épaisseur prédéterminée, apte à produire le son en association avec la bobine et à le diriger grâce à une coque en forme de cloche, également en matière plastique, associée d' une part à la membrane par son bord périphérique inférieur ouvert, et d' autre part à l' aimant se logeant au moins partiellement dans une ouverture correspondante ménagée sur le dos de la coque, ces éléments constituant un ensemble définissant entre eux une chambre interne étanche à l' intérieur de laquelle est disposée la bobine électrique en liaison étroite avec la membrane et avec l' aimant.To this end, the invention relates to a water speaker of the type constituted by a sound diffusion element which is associated with a coil consisting of an insulating support and an electric winding, itself in connection with a magnet. peripheral, so as to obtain the transformation of an electrical voltage into a musical frequency, characterized in that the sound diffusion element is a membrane constituted by a circular plastic plane wall, of predetermined thickness, capable of producing the sound in association with the coil and to direct it by means of a bell - shaped shell, also made of plastic, associated on the one hand with the membrane by its open lower peripheral edge, and on the other hand with the magnet. lodging at less partially in a corresponding opening formed on the back of the shell, these elements constituting an assembly defining between them a sealed internal chamber inside which is disposed the electrical coil in close connection with the membrane and with the magnet.
La présente invention concerne également les caractéristiques qui ressortiront au cours de la description qui va suivre, et qui devront être considérées isolément ou selon toutes leurs combinaisons techniques possibles .The present invention also relates to the features which will emerge during the following description, which should be considered in isolation or in all their possible technical combinations.

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 ternes be-r-ds périphériques respecti.fs., 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. 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.According to another characteristic of the invention, which is particularly visible in FIG. 3, the shell 7 is associated with the membrane 2, close to the peripheral devices respectively, via a external peripheral lip 14 issuing from the membrane 2 and obtained with it during the same molding operation of a plastic material, said lip 14 forming a cleat against the inner peripheral side wall of which the interlocking wall is supported by outer side of its lower peripheral edge 8 of the shell 7. Moreover, the external fixation and the axial retention of the membrane 2 with respect to the shell 7 are carried out via 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 membraneIn order to perfect the tightness, the 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 .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 lower peripheral zone of the assembly formed by the cleat. 14, the base 8 of the shell 7 and the screws.
