Description

La présente invention concerne le domaine général de l'isolation des microphones de prise de son. La présente invention décrit plus particulièrement un dispositif de protection anti-vent et anti-vibratoire.The present invention relates to the general field of sound pickup microphone isolation. The present invention more particularly describes a device for protecting against wind and vibration.

Un microphone est un objet habituellement composé d'un ou plusieurs capteurs acoustiques, d'un dispositif de transduction, d'une éventuelle prise électrique véhiculant le signal utile, d'un éventuel enregistreur de ce signal, d'un éventuel transmetteur haute fréquence et d'un corps formant l'objet. Par nature, un microphone est sensible aux flux d'air environnants et aux vibrations éventuelles transmises par son support. De très nombreux microphones d'usage courant sont constitués de deux parties : une partie avant composée de ports acoustiques et une partie arrière composée de l'électronique.A microphone is an object usually composed of one or more acoustic sensors, a transducing device, a possible electrical socket carrying the useful signal, a possible recorder of this signal, a possible high frequency transmitter and of a body forming the object. By nature, a microphone is sensitive to surrounding air flows and any vibrations transmitted by its support. A large number of commonly used microphones consist of two parts: a front part composed of acoustic ports and a rear part made up of electronics.

Certains dispositifs de protection anti-vibratoire sont par exemple décrits dans les documents anciens US1653109 , US3155780 , US4396807 ou, plus récemment depuis l'apparition de techniques nouvelles, décrits dans les documents FR2893213 (Revendications 1 à 6) ou US8121333 . Tous ces dispositifs se fondent sur l'application du grand principe de réduction de la transmission vibratoire basé sur l'effet d'inertie d'une masse fixée par un ou plusieurs ressorts à un support vibrant. Le microphone, considéré inerte et rigide en approximation basse fréquence, joue donc le rôle de la masse. Les ressorts peuvent être ainsi nommés "isolateurs" et seuls ceux possédants deux extrémités sont concernés par le présent exposé et par les revendications. Lesdits isolateurs sont donc insérés entre le microphone d'un côté et le support vibrant de l'autre. Ces dispositifs, souvent nommés "suspensions de microphone", peuvent être associés à une protection anti-vent complémentaire telle une mousse ou une cage autour des ports acoustiques du microphone, ladite protection étant rigidement liée au microphone dans sa partie avant. Dans le cas où la protection est une cage, ou assimilée, celle-ci peut être constituée ou recouverte de matières poreuses diverses. Voir par exemple les documents DE19934260 et US2014211974 .Some anti-vibratory protection devices are for example described in the old documents US1653109 , US3155780 , US4396807 or, more recently since the appearance of new techniques, described in the documents FR2893213 (Claims 1 to 6) or US8121333 . All these devices are based on the application of the great principle of reducing the vibratory transmission based on the inertia effect of a mass fixed by one or more springs to a vibrating support. The microphone, considered inert and rigid in low frequency approximation, therefore plays the role of mass. The springs may be so-called "insulators" and only those possessing two ends are concerned by the present disclosure and by the claims. Said insulators are inserted between the microphone on one side and the vibrating support on the other. These devices, often called "microphone suspensions", may be associated with a complementary wind shield such as a foam or a cage around the acoustic ports of the microphone, said protection being rigidly connected to the microphone in its front part. In the case where the protection is a cage, or assimilated, it may be constituted or covered with various porous materials. See for example documents DE19934260 and US2014211974 .

Le document US20060227991 montre l'exemple d'un dispositif qui revendique une certaine combinaison mécanique entre une protection anti-vent et une protection anti-vibratoire. Cependant, de même que les dispositifs cités ci-dessus, le matériau poreux protège exclusivement la partie avant du microphone, alors que la suspension se situe complètement à l'arrière.The document US20060227991 shows the example of a device that claims a certain mechanical combination between a windshield and an anti-vibration protection. However, as with the devices mentioned above, the porous material exclusively protects the front part of the microphone, while the suspension is completely at the back.

Pour être le plus efficace possible, une suspension de microphone doit notamment pouvoir s'étendre sur la plus grande longueur possible du corps du microphone. De même, pour être le plus efficace possible, une protection anti-vent doit pouvoir entourer les ports acoustiques le plus largement possible dans toutes les directions. Pour bon nombre de microphones, notamment de taille réduite, ce besoin conflictuel d'espace entraine souvent un compromis dégradé entre les efficacités de protection anti-vent et anti-vibratoire.To be as effective as possible, a microphone suspension must in particular be able to extend over the largest possible length of the body of the microphone. Similarly, to be as effective as possible, a wind shield must be able to surround the acoustic ports as widely as possible in all directions. For many microphones, especially of small size, this conflicting need for space often leads to a compromised compromise between the effectiveness of protection against wind and vibration.

Le document GB2184916 montre l'exemple d'une grande cage anti-vent entourant complètement le microphone dans sa totalité, à des fins d'efficacité anti-vent renforcée. La cage, considérée rigide et poreuse, est éventuellement recouverte de matières diverses également poreuses, telles que du tissu ou de la fausse fourrure. Le microphone est donc totalement entouré par une cavité, à l'exception de sa propre structure porteuse constituée par un dispositif anti-vibratoire entièrement inclus dans la cavité. Le microphone est suspendu de façon flexible relativement au support, mais la cage elle-même est fixée rigidement audit support. Cette rigidité de fixation entraîne une sensibilité vibratoire importante de la cage et transmet indirectement les vibrations du support au microphone par voie acoustique.The document GB2184916 shows the example of a large windscreen completely surrounding the microphone in its entirety, for purposes of enhanced windproof efficiency. The cage, considered rigid and porous, is possibly covered with various materials also porous, such as fabric or faux fur. The microphone is thus completely surrounded by a cavity, except for its own supporting structure constituted by an anti-vibration device entirely included in the cavity. The microphone is flexibly suspended relative to the support, but the cage itself is rigidly attached to said support. This rigidity of attachment causes a significant vibratory sensitivity of the cage and indirectly transmits the vibrations of the support to the microphone acoustically.

Les documents FR2893213 et GB2529069 présentent deux variantes de combinaisons entre un dispositif anti-vibratoire pour microphone et un dispositif anti-vibratoire pour cage anti-vent associée. Pour chacune de ces deux variantes, le microphone et les deux dispositifs sont entièrement inclus dans la cavité. Ces deux variantes ont un inconvénient : il est très difficile d'en réaliser des versions de taille réduite, notamment du fait de la flexibilité relative entre le microphone et la cage pouvant entraîner une augmentation notable du risque de bruits divers.The documents FR2893213 and GB2529069 present two variants of combinations between a microphone anti-vibratory device and an anti-vibratory device for associated windscreen cage. For each of these two variants, the microphone and the two devices are fully included in the cavity. These two variants have a disadvantage: it is very difficult to make versions of reduced size, especially because the relative flexibility between the microphone and the cage that can significantly increase the risk of various noises.

Le dispositif selon l'invention permet de remédier aux différents inconvénients décrits ci-dessus, notamment lorsque les microphones sont de taille réduite ou lorsque la partie arrière du microphone est petite comparativement à sa partie avant.The device according to the invention overcomes the various disadvantages described above, especially when the microphones are reduced in size or when the rear part of the microphone is small compared to its front part.

Selon son mode principal de réalisation, le dispositif comporte d'une part une cage rigide formant une cavité complète autour du microphone, sans précision particulière sur la nature de la fixation du microphone dans la cage, ladite cage étant constituée ou recouverte de matériaux poreux. Il est à noter que le descriptif desdits matériaux ne fait pas partie de la présente invention. D'autre part, le dispositif comporte un ou plusieurs isolateurs fixés d'un côté à la cage et de l'autre au support. Chaque isolateur, globalement filaire et courbe, possédant deux extrémités, est constitué d'un ou plusieurs matériaux à effet ressort. Le dispositif selon l'invention est particulièrement caractérisé par le fait que les isolateurs sont fixés à l'extérieur la cage.According to its main embodiment, the device comprises firstly a rigid cage forming a complete cavity around the microphone, without particular details on the nature of the fixation of the microphone in the cage, said cage being constituted or covered with porous materials. It should be noted that the description of said materials is not part of the present invention. On the other hand, the device comprises one or more insulators attached on one side to the cage and the other to the support. Each insulator, generally wired and curved, having two ends, consists of one or more spring-effect materials. The device according to the invention is particularly characterized by the fact that the insulators are attached to the outside of the cage.

  • The Figure 2 represents a variant of the device according to claim 2.
  • The Figures 3 and 4 represent variants of the device according to claims 3, 4 and 5.

Toutes les Figures font apparaître les détails des revendications 7 et 10.All figures show the details of claims 7 and 10.

En référence à ces dessins, le microphone (1) ne fait pas partie de l'invention, mais sa représentation est nécessaire à la compréhension du dispositif.With reference to these drawings, the microphone (1) does not form part of the invention, but its representation is necessary for the understanding of the device.

Dans son mode principal de réalisation, le dispositif comporte : une cage (2) considérée rigide au sens des vibrations en approximation basse fréquence ; une cavité (3) entourant complètement le microphone (1) ; un ou plusieurs isolateurs (4) et un support (5). Le support (5) est un élément qui subit directement les vibrations dont le microphone doit être protégé. Les isolateurs (4), situés à l'extérieur de la cage (2), constituent l'interface d'isolation vibratoire entre le support (5) et ladite cage (2). La cage (2), constituée ou recouverte de matériaux poreux, assure la protection anti-vent du microphone (1). Le mode de fixation du microphone dans la cage n'est pas précisé ; il peut donc être quelconque. La taille et la forme de la cage (2) doivent être choisies selon la physionomie du microphone (1) et du degré désiré de protection anti-vent, sachant que l'efficacité croît avec l'augmentation de volume de la cavité (3).In its main embodiment, the device comprises: a cage (2) considered rigid in the sense of vibrations in low frequency approximation; a cavity (3) completely surrounding the microphone (1); one or more insulators (4) and a support (5). The support (5) is an element that directly undergoes the vibrations whose microphone must be protected. Insulators (4), located outside the cage (2), constitute the vibratory isolation interface between the support (5) and said cage (2). The cage (2), made of or covered with porous materials, provides the wind protection of the microphone (1). The method of fixing the microphone in the cage is not specified; it can therefore be any. The size and shape of the cage (2) must be chosen according to the appearance of the microphone (1) and the desired degree of wind protection, knowing that the efficiency increases with the increase in volume of the cavity (3) .

Selon le mode de réalisation décrit à la Figure 2, le microphone (1) est rigidement fixé à la cage par une structure interne (6). Cette structure garantit ainsi la constitution d'un assemblage rigide et massique formé par la cage (2), le microphone (1) et la structure (6). Les formes affinées de cette structure (6) doivent être choisies pour que l'effet de cavité, notamment nécessaire à la qualité de protection anti-vent, soit respecté.According to the embodiment described in Figure 2 the microphone (1) is rigidly fixed to the cage by an internal structure (6). This structure thus guarantees the constitution of a rigid and mass assembly formed by the cage (2), the microphone (1) and the structure (6). The refined shapes of this structure (6) must be chosen so that the cavity effect, particularly necessary for the quality of wind protection, is respected.

Selon le mode de réalisation représenté à la Figure 3, le microphone (1) est rendu amovible par couplage rigide à un élément profilé creux (7), tel un tube, ledit élément étant rigidement fixé à la cage (2). La Figure 3 montre le cas où le microphone (1) sort par l'arrière de la cage (2), dans la mesure où les ports acoustiques (1b) sont considérés à l'avant. Dans ce cas, la partie arrière (la) du microphone (1) ne possède pas de ports acoustiques (1b). C'est donc cette partie arrière (la) qui est couplée rigidement à l'élément (7).According to the embodiment shown in Figure 3 , the microphone (1) is made removable by rigid coupling to a hollow section member (7), such as a tube, said member being rigidly fixed to the cage (2). The Figure 3 shows the case where the microphone (1) comes out of the back of the cage (2), since the acoustic ports (1b) are considered at the front. In this case, the rear part (la) of the microphone (1) does not have acoustic ports (1b). It is therefore this rear part (la) which is rigidly coupled to the element (7).

Selon le mode de réalisation représenté à la Figure 4, le microphone (1) sort par l'avant, par opposition au mode représenté à la Figure 3. A titre indicatif, la Figure 4 présente une possible séparation de la cage (2), non revendiquée, impliquant la formation des parties (2a) et (2b). Cette séparation est d'ailleurs possible dans tous les modes de réalisation.According to the embodiment shown in Figure 4 , the microphone (1) comes out from the front, as opposed to the mode shown in Figure 3 . As an indication, the Figure 4 presents a possible separation of the cage (2), unclaimed, involving the formation of the parts (2a) and (2b). This separation is also possible in all embodiments.

Par souci de clarté et de simplification, les isolateurs (4) sont représentés selon les revendications 7 et 10 dans toutes les Figures.For the sake of clarity and simplification, the insulators (4) are shown in claims 7 and 10 in all the figures.
