Description

L'invention concerne une montre à sonnerie, qui est munie d'une membrane acoustique. La montre comprend une boîte de montre constituée essentiellement d'une carrure et d'un fond fixé étanchement et de manière amovible sur la carrure. Une glace est disposée sur un côté opposé de la carrure pour fermer étanchement ladite boîte. Un mouvement horloger est maintenu à l'intérieur de la boîte de montre et muni d'un mécanisme de sonnerie susceptible d'être activé dans des périodes déterminées pour produire un son. Au moins une membrane acoustique est reliée à la boîte pour rayonner le son produit par le mécanisme de sonnerie vers l'extérieur de la boîte.The invention relates to a striking watch, which is provided with an acoustic membrane. The watch comprises a watch case consisting essentially of a middle and a bottom fixed and securely attached to the middle part. An ice cream is disposed on an opposite side of the middle to seal said box. A watch movement is maintained inside the watch case and provided with a striking mechanism that can be activated in specified periods of time to produce a sound. At least one acoustic membrane is connected to the box to radiate the sound produced by the striking mechanism to the outside of the box.

Dans le domaine de l'horlogerie, une architecture traditionnelle est utilisée pour réaliser des mouvements, qui peuvent également comprendre des mécanismes de sonnerie. Un tel mécanisme de sonnerie peut être activé dans des périodes bien déterminées pour signaler une alarme programmée ou des répétitions minutes. Pour une réalisation conventionnelle d'une montre à sonnerie, le mécanisme de sonnerie peut comprendre un timbre. Ce timbre est généralement un fil métallique de forme circulaire, qui entoure une partie du mouvement horloger dans une cage de montre. Ce timbre est fixé à un porte-timbre solidaire d'une platine de montre. La vibration du timbre est produite par l'impact d'au moins un marteau contre le timbre dans des périodes déterminées.In the field of watchmaking, a traditional architecture is used to perform movements, which may also include ringing mechanisms. Such a striking mechanism can be activated in well-defined periods to signal a programmed alarm or minute repetitions. For a conventional embodiment of a bell watch, the striking mechanism may comprise a stamp. This stamp is usually a circular wire, which surrounds part of the watch movement in a watch cage. This stamp is attached to a stamp holder attached to a watch plate. The vibration of the stamp is produced by the impact of at least one hammer against the stamp in certain periods.

Dans le cas d'une montre à sonnerie, telle qu'une montre musicale, le son est produit par les vibrations de lames d'un clavier. Les lames du clavier sont réalisées ensemble avec un talon du clavier, qui est monté sur la platine de montre. Pour la production d'une musique par exemple en des périodes de temps programmées, les lames du clavier sont levées puis relâchées par des goupilles solidaires d'un cylindre ou d'un disque en rotation. Chaque lame peut donc fléchir par l'action d'une goupille correspondante du cylindre ou du disque, et dès qu'elle est relâchée, elle oscille principalement à sa première fréquence propre. Le clavier musical est enfermé dans la boîte de montre. De ce fait, les vibrations générées par les lames activées, sont transmises aux pièces d'habillage de la montre.In the case of a ringing watch, such as a musical watch, the sound is produced by the blade vibrations of a keyboard. The keyboard blades are made together with a keyboard heel, which is mounted on the watch plate. For the production of a music for example in programmed time periods, the keyboard blades are lifted and released by pins integral with a cylinder or a rotating disc. Each blade can therefore flex by the action of a corresponding pin of the cylinder or disk, and as soon as it is released, it oscillates mainly at its first natural frequency. The musical keyboard is enclosed in the watch case. As a result, the vibrations generated by the activated blades are transmitted to the display parts of the watch.

Les pièces d'habillage de la montre sont par exemple la carrure, la lunette, la glace ou le fond de la boîte. Lorsqu'un son est produit soit par un timbre frappé par un marteau, soit par une ou plusieurs lames du clavier en vibration, ces pièces d'habillage sont capables de rayonner le son produit dans l'air. Dans une montre à sonnerie traditionnelle, le rendement acoustique, sur la base de la transduction vibro-acoustique complexe des pièces d'habillage, est faible. Pour améliorer et augmenter le niveau acoustique perçu par l'utilisateur de la montre à sonnerie, il doit être tenu compte de la matière, de la géométrie et des conditions aux limites desdites pièces d'habillage. Les configurations de ces pièces d'habillage sont aussi dépendantes de l'esthétique de la montre et des contraintes de fonctionnement, ce qui peut limiter les possibilités d'adaptation.The display parts of the watch are for example the middle part, the bezel, the ice or the bottom of the box. When a sound is produced either by a stamp struck by a hammer or by one or more blades of the vibrating keyboard, these pieces of clothing are able to radiate the sound produced in the air. In a traditional bell watch, the acoustic efficiency, based on the complex vibro-acoustic transduction of the trim pieces, is low. In order to improve and increase the sound level perceived by the user of the bell watch, the material, the geometry and the boundary conditions of said trim pieces must be taken into account. The configurations of these pieces of clothing are also dependent on the aesthetics of the watch and operating constraints, which may limit the possibilities of adaptation.

Il est connu dans la technique horlogère d'utiliser dans une montre notamment électronique, une membrane du type acoustique, qui est dédiée à la transduction vibro-acoustique. Pour activer une telle membrane dans une montre électronique, il est placé un élément piézoélectrique par exemple sur la membrane pour la faire vibrer. Pour que le rayonnement sonore de la membrane ne soit pas perdu dans la montre, qui doit être étanche, il peut être prévu un double fond de la boîte de montre, qui est ouvert vers l'extérieur. Dans ce cas, le fond de la boîte de montre présente une ou plusieurs ouvertures pour la transmission du son de la membrane en vibration.It is known in the art of horology to use in a particular electronic watch, a membrane of the acoustic type, which is dedicated to vibro-acoustic transduction. To activate such a membrane in an electronic watch, it is placed a piezoelectric element for example on the membrane to make it vibrate. So that the sound radiation of the membrane is not lost in the watch, which must be sealed, it can be provided a double bottom of the watch case, which is open to the outside. In this case, the bottom of the watch case has one or more openings for transmitting the sound of the vibrating membrane.

Avec une telle construction d'une montre électronique à membrane acoustique, il est rencontré souvent des problèmes d'étanchéité et de corrosion de ladite membrane. Cette membrane doit en principe avoir sa première fréquence propre de vibration, qui est le mode efficace de rayonnement, dans la bande de fréquence acoustique utile, alors que sa deuxième fréquence propre, qui est un mode peu efficace, doit être si possible en dehors de cette bande audible. Comme cette membrane est habituellement réalisée en acier, les première et seconde fréquences propres de vibration ne remplissent pas les conditions susmentionnées de façon optimale. De plus, un amortissement rapide est constaté, ce qui est un inconvénient.With such a construction of an electronic acoustic diaphragm watch, it is often encountered problems of sealing and corrosion of said membrane. This membrane should in principle have its first natural frequency of vibration, which is the effective mode of radiation, in the useful acoustic frequency band, while its second eigenfrequency, which is an inefficient mode, must be if possible outside of this audible band. As this membrane is usually made of steel, the first and second natural frequencies of vibration do not fulfill the aforementioned conditions optimally. In addition, a rapid depreciation is found, which is a disadvantage.

Dans une montre à sonnerie standard, qui est munie par exemple d'une membrane acoustique, cette membrane est prise en sandwich entre une partie de la carrure et le fond de la boîte de montre. Dans le cas d'une montre de luxe, le fond peut être réalisé dans un matériau précieux, tel que de l'or. Il peut se produire au contact de la membrane généralement en acier avec le fond en or, une différence de potentiel électro-chimique surtout dans un milieu humide. Cela est susceptible de favoriser la corrosion de ladite membrane au niveau du contact avec le fond en or, ce qui est un inconvénient.In a standard bell watch, which is provided for example with an acoustic membrane, this membrane is sandwiched between a portion of the middle part and the bottom of the watch case. In the case of a luxury watch, the bottom can be made of a precious material, such as gold. It can occur in contact with the membrane usually made of steel with the gold bottom, an electrochemical potential difference especially in a humid environment. This is likely to promote the corrosion of said membrane at the contact with the gold background, which is a drawback.

L'invention a donc pour but de pallier aux inconvénients de l'état de la technique en fournissant une montre à sonnerie, qui est munie d'une membrane acoustique, pour obtenir un bon rendement acoustique lors du fonctionnement d'un mécanisme de sonnerie dans la boîte de montre.The invention therefore aims to overcome the drawbacks of the state of the art by providing a bell watch, which is provided with an acoustic membrane, to obtain a good acoustic performance during operation of a striking mechanism in the watch box.

A cet effet, l'invention concerne une montre à sonnerie comprenant les caractéristiques définies dans les revendications indépendantes 1 et 2.For this purpose, the invention relates to a striking watch comprising the features defined in the independent claims 1 and 2.

Des formes d'exécution particulières de la montre à sonnerie sont définies dans les revendications dépendantes 3 à 14.Particular embodiments of the striking watch are defined in the dependent claims 3 to 14.

Un avantage de la montre à sonnerie selon la présente invention, réside dans le fait que la membrane acoustique dans la boîte de montre est réalisée dans un métal amorphe ou verre métallique. Dans ces conditions, lorsque le mécanisme de sonnerie produit un son ou une succession de notes de musique, la membrane acoustique est susceptible de vibrer avec une première fréquence propre située dans la bande acoustique utile entre 1 et 4 kHz. La seconde fréquence propre de vibration, qui est généralement inefficace en termes de rayonnement sonore, est avantageusement située au-dessus de 4 kHz avec cette membrane en métal amorphe. De ce fait, elle n'affecte pas le rayonnement sonore de la membrane à sa première fréquence propre. Ce sont les propriétés physiques, telles que la masse volumique et le module d'Young du métal amorphe, qui permettent d'obtenir ces fréquences propres voulues. Grâce à une telle membrane en métal amorphe, un amortissement très faible est constaté, ce qui procure un très bon rendement sonore.An advantage of the striking watch according to the present invention lies in the fact that the acoustic membrane in the watch case is made of an amorphous metal or metallic glass. Under these conditions, when the striking mechanism produces a sound or a succession of musical notes, the acoustic membrane is likely to vibrate with a first natural frequency located in the acoustic band useful between 1 and 4 kHz. The second natural frequency of vibration, which is generally ineffective in terms of sound radiation, is advantageously located above 4 kHz with this amorphous metal membrane. As a result, it does not affect the sound radiation of the membrane at its first natural frequency. It is the physical properties, such as the density and the Young's modulus of the amorphous metal, which make it possible to obtain these desired natural frequencies. With such an amorphous metal membrane, a very low damping is found, which provides a very good sound output.

Avantageusement, cette membrane acoustique est pincée étanchement sur sa bordure entre une pièce de liaison liée à la platine de montre et le fond de la boîte de montre, ce qui constitue un double fond. Une ou plusieurs ouvertures sont prévues à travers le fond pour le rayonnement sonore de la membrane acoustique. Avec une telle membrane en métal amorphe inoxydable, il n'y a en principe pas de différence de potentiel électro-chimique entre la membrane en contact avec le fond de la boîte, même si le fond est en or. Aucune corrosion n'est donc constatée même dans un milieu humide. De plus, l'usinage d'une telle membrane en métal amorphe est moins cher que l'usinage d'une membrane en acier ou en titane. Cela permet de réaliser également des pièces ayant des formes complexes, ce qui peut apporter un aspect de haute technologie à la montre à sonnerie.Advantageously, this acoustic membrane is pinched sealingly on its edge between a connecting piece connected to the watch plate and the bottom of the watch case, which constitutes a double bottom. One or more openings are provided through the bottom for the sound radiation of the acoustic membrane. With such a stainless amorphous metal membrane, there is in principle no electrochemical potential difference between the membrane in contact with the bottom of the box, even if the bottom is gold. No corrosion is therefore observed even in a humid environment. In addition, the machining of such an amorphous metal membrane is less expensive than the machining of a steel or titanium membrane. This also allows for pieces with complex shapes, which can bring a high-tech aspect to the bell watch.

Les buts, avantages et caractéristiques de la montre à sonnerie apparaîtront mieux dans la description suivante sur la base d'au moins une forme d'exécution non limitative illustrée par le dessin sur lequel :
la figure 1 représente de manière simplifiée une coupe partielle d'une montre à sonnerie munie d'une membrane acoustique selon l'invention.
The purposes, advantages and characteristics of the ring watch will appear better in the following description on the basis of at least one non-limiting embodiment illustrated by the drawing in which:
the figure 1 represents in simplified manner a partial section of a bell-shaped watch provided with an acoustic membrane according to the invention.

Dans la description suivante, toutes les parties de la montre à sonnerie, qui sont bien connues d'un homme du métier dans ce domaine technique, ne sont décrites que de manière simplifiée.In the following description, all parts of the striking watch, which are well known to those skilled in the art, are only described in a simplified manner.

La figure 1 représente donc une coupe partielle simplifiée d'une montre à sonnerie 1 à membrane acoustique 10. La montre comprend une boîte de montre, qui est composée essentiellement d'une carrure 4, sur laquelle est fixée étanchement d'un côté une lunette 3 et d'un côté opposé un fond 5. Le fond 5 est monté par des moyens connus et de manière amovible sur la carrure 4 avec une garniture d'étanchéité 9. Une glace de montre 2 est fixée notamment à la lunette 3 pour fermer étanchement la boîte de montre. Un cadran 13 est maintenu en bordure sur la carrure et disposé au-dessous de la glace de montre 2. Dans le cas d'une montre mécanique à sonnerie 1, des aiguilles d'indication de l'heure, qui ne sont pas représentées, sont prévues sur le cadran, qui porte généralement des index horaires en périphérie.The figure 1 thus represents a simplified partial section of a ring-type watch 1 with an acoustic membrane 10. The watch comprises a watch case, which is essentially composed of a caseband 4, on which is fixed on one side a case 3 and a case. A bottom 5 is mounted by known means and removably on the middle part 4 with a seal 9. A watch glass 2 is fixed in particular to the bezel 3 to close the box tightly. of watch. A dial 13 is held at the edge on the middle part and placed beneath the watch glass 2. In the case of a mechanical bell watch 1, time indication hands, which are not shown, are provided on the dial, which usually carries hourly indices on the periphery.

La montre à sonnerie 1 comprend également un mouvement horloger 20, qui est généralement monté sur une platine 14. Une pièce de bordure 12 est fixée à la platine 14, ce qui définit une cage de montre. Habituellement aussi bien la platine 14 que la pièce de bordure sont réalisées dans un matériau métallique.The striking watch 1 also comprises a watch movement 20, which is generally mounted on a plate 14. An edge piece 12 is fixed to the plate 14, which defines a watch cage. Usually both the plate 14 and the edge piece are made of a metallic material.

Le mouvement horloger comprend un mécanisme de sonnerie, non représenté. Ce mécanisme de sonnerie peut comprendre au moins un timbre monté sur un porte-timbre solidaire de la platine 14, et au moins un marteau monté rotatif sur la platine pour venir frapper ledit timbre dans des périodes déterminées. Le timbre généralement de forme circulaire entoure les diverses parties du mouvement horloger. Un tel mécanisme de sonnerie est prévu pour signaler une alarme programmée ou des répétitions minutes.The watch movement comprises a striking mechanism, not shown. This striking mechanism may comprise at least one stamp mounted on a stamp holder secured to the plate 14, and at least one hammer rotatably mounted on the plate to strike said stamp in specified periods. The generally circular stamp surrounds the various parts of the watch movement. Such a striking mechanism is provided to signal a programmed alarm or minute repetitions.

Dans une forme d'exécution plus élaborée d'une montre musicale, le mécanisme de sonnerie peut comprendre un clavier avec un ensemble de lames reliées à un talon, qui est fixé sur la platine 14. Le son ou la succession de notes de musique sont produits par les vibrations de lames du clavier. Chaque lame est configurée pour la production d'une note particulière. Pour produire une musique par exemple dans des périodes programmées, les lames du clavier sont levées puis relâchées par des goupilles solidaires d'un cylindre ou d'un disque en rotation sur la platine 14. Chaque lame activée oscille principalement à sa première fréquence propre. Les vibrations générées par les lames activées, sont transmises aux pièces d'habillage de la montre, qui doivent permettre de rayonner acoustiquement le son produit par chaque lame en vibration.In a more elaborate embodiment of a musical watch, the striking mechanism may comprise a keyboard with a set of blades connected to a heel, which is attached to the deck 14. The sound or succession of musical notes are produced by keyboard blade vibrations. Each blade is configured to produce a particular note. To produce music for example in programmed periods, the keyboard blades are lifted and released by pins secured to a cylinder or disk rotating on the plate 14. Each activated blade oscillates mainly at its first natural frequency. The vibrations generated by the activated blades are transmitted to the watch's trim pieces, which must make it possible to radiate acoustically the sound produced by each vibrating blade.

La montre à sonnerie 1 comprend essentiellement une membrane acoustique 10 pour améliorer le rendement acoustique du son produit par le mécanisme de sonnerie. Cette membrane acoustique est réalisée dans un métal amorphe ou verre métallique, qui peut être un matériau inoxydable. L'épaisseur de cette membrane peut être inférieure ou égale à 1 mm. Dans cette forme d'exécution, la membrane acoustique 10 est en forme de cuvette en une pièce, dont le bord supérieur est monté de manière étanche par une garniture annulaire 8 sur un rebord annulaire intérieur du fond 5 de la boîte. Le diamètre de cette cuvette, qui peut être équivalent au diamètre de la glace 2 de montre, peut se situer entre 20 et 40 mm. Un support 11 de forme annulaire supporte d'un côté la platine 14 avec la pièce de bordure 12 et s'appuie sur le bord supérieur de la membrane 10 acoustique. Au moment de la fixation de la carrure 4 sur le fond 5 de la boîte de montre, le support 11 et le bord périphérique de la membrane acoustique 10 sont pincés entre la carrure 4 et le rebord du fond 5.The striking watch 1 essentially comprises an acoustic membrane 10 for improving the acoustic performance of the sound produced by the striking mechanism. This acoustic membrane is made of an amorphous metal or metallic glass, which may be a stainless material. The thickness of this membrane may be less than or equal to 1 mm. In this embodiment, the acoustic membrane 10 is cup-shaped in one piece, the upper edge of which is sealingly mounted by an annular gasket 8 on an inner annular flange of the bottom 5 of the box. The diameter of this bowl, which may be equivalent to the diameter of the watch ice 2, may be between 20 and 40 mm. An annular support 11 supports the plate 14 on one side with the edge piece 12 and bears on the upper edge of the acoustic membrane. At the time of attachment of the caseband 4 on the bottom 5 of the watch case, the support 11 and the peripheral edge of the acoustic membrane 10 are clamped between the caseband 4 and the rim of the bottom 5.

La partie centrale de la membrane acoustique n'est pas en contact avec le support 11 et la surface intérieure du fond 5. De ce fait, un espace suffisant 7 dans la boîte est prévu pour que la membrane acoustique puisse librement vibrer et rayonner acoustiquement. L'ensemble de la membrane acoustique 10 et du fond 5 constitue ainsi un double fond. Une ou plusieurs ouvertures 6 sont également prévues latéralement à travers le fond 5 pour permettre à la membrane acoustique de rayonner le son produit par le mécanisme de sonnerie vers l'extérieur.The central part of the acoustic membrane is not in contact with the support 11 and the inner surface of the bottom 5. As a result, a sufficient space 7 in the box is provided so that the acoustic membrane can freely vibrate and radiate acoustically. The entire acoustic membrane 10 and the bottom 5 thus constitutes a double bottom. One or more openings 6 are also provided laterally through the bottom 5 for allow the acoustic membrane to radiate the sound produced by the striking mechanism to the outside.

Lors du fonctionnement du mécanisme de sonnerie, le son produit par ledit mécanisme de sonnerie est transmis directement à la membrane acoustique pour la faire vibrer. Une transmission de vibration à la membrane acoustique est également fournie en bordure de la membrane acoustique par les pièces de liaison 11, 12 et 14. Comme la membrane acoustique est faite en métal amorphe, elle est susceptible de vibrer à une première fréquence propre située dans la bande acoustique utile entre 1 et 4 kHz. La seconde fréquence propre de vibration est par contre située au-dessus de 4 kHz. Ces fréquences propres voulues de vibration sonore de la membrane en métal amorphe sont dépendantes des propriétés physiques, telles que la masse volumique et le module d'Young. De plus avec une telle membrane en métal amorphe, il est constaté un amortissement très faible ce qui procure un très bon rendement sonore et une augmentation du niveau sonore perçu de cette membrane acoustique.During operation of the striking mechanism, the sound produced by said striking mechanism is transmitted directly to the acoustic membrane to vibrate. A vibration transmission to the acoustic membrane is also provided at the edge of the acoustic membrane by the connecting pieces 11, 12 and 14. Since the acoustic membrane is made of amorphous metal, it is able to vibrate at a first natural frequency located in the useful acoustic band between 1 and 4 kHz. The second natural frequency of vibration is on the other hand located above 4 kHz. These desired natural frequencies of sound vibration of the amorphous metal membrane are dependent on physical properties, such as density and Young's modulus. Moreover with such an amorphous metal membrane, there is a very low damping which provides a very good sound performance and an increase in the perceived sound level of this acoustic membrane.

Il est à noter que cette membrane acoustique en métal amorphe ou verre métallique peut être fabriquée moins cher qu'une membrane traditionnelle en acier ou en titane. Elle peut être par exemple fabriquée à partir de l'état fondu du métal amorphe, suivi d'une trempe rapide. Grâce au fait que cette membrane en métal amorphe est inoxydable, elle peut être montée sur un fond par exemple en métal précieux, tel que l'or. Aucune différence de potentiel électro-chimique n'est ainsi constatée même dans un milieu humide, ce qui fait qu'aucune corrosion ne survient au contact de la membrane 10 et du fond 5.It should be noted that this acoustic membrane of amorphous metal or metallic glass can be manufactured cheaper than a traditional membrane made of steel or titanium. It may for example be manufactured from the molten state of the amorphous metal, followed by rapid quenching. Due to the fact that this amorphous metal membrane is stainless, it can be mounted on a background for example of precious metal, such as gold. No difference in electrochemical potential is thus observed even in a humid environment, so that no corrosion occurs in contact with the membrane 10 and the bottom 5.

L'avantage d'utiliser une membrane en métal amorphe vient du fait que lors de sa fabrication, les atomes, qui composent ledit métal amorphe, ne s'arrangent pas selon une structure particulière, ce qui est différent d'une structure cristalline. Le métal amorphe se différencie par une limite d'élasticité plus élevée par exemple deux fois plus élevée que celle d'un matériau cristallin traditionnel. La membrane acoustique réalisée avec le métal amorphe peut ainsi subir une plus forte contrainte avant d'arriver à sa limite d'élasticité. Ceci conduit également à avoir un amortissement plus faible de la membrane en vibration.The advantage of using an amorphous metal membrane comes from the fact that during its manufacture, the atoms, which make up said amorphous metal, do not arrange in a particular structure, which is different from a crystalline structure. The amorphous metal differs by a higher yield strength, for example twice as high as that of a traditional crystalline material. The acoustic membrane made with the The amorphous metal can thus undergo a greater stress before reaching its elastic limit. This also leads to having a lower damping of the membrane in vibration.

Ce verre métallique ou métal amorphe peut être par exemple un alliage métallique à base de titane, zirconium et béryllium. Ainsi à titre d'exemple plus spécifique, l'alliage de métal amorphe peut comprendre 41% de zirconium, 14% de titane, 12% de cuivre, 10% de nickel et 23% de béryllium. Le module d'Young de cet alliage vaut 105 GPa et la limite d'élasticité vaut 1.9 GPa. L'alliage de métal amorphe peut également être constitué de 57.5 % de platine, de 14.7% de cuivre, de 5.3% de nickel et de 22.5% de phosphore. Le module d'Young de vaut dans ce cas 98 GPa et la limite d'élasticité vaut 1.4 GPa.This metal glass or amorphous metal may be for example a metal alloy based on titanium, zirconium and beryllium. Thus, by way of a more specific example, the amorphous metal alloy may comprise 41% of zirconium, 14% of titanium, 12% of copper, 10% of nickel and 23% of beryllium. The Young's modulus of this alloy is 105 GPa and the elastic limit is 1.9 GPa. The amorphous metal alloy may also consist of 57.5% platinum, 14.7% copper, 5.3% nickel and 22.5% phosphorus. The Young's modulus is in this case 98 GPa and the elastic limit is 1.4 GPa.
