Description

L'invention concerne une montre musicale ou à sonnerie, qui est munie d'un agencement à rayonnement acoustique. La montre comprend une boîte de montre, qui est constituée au moins d'une carrure et d'un fond fixé de manière amovible sur la carrure, et au moins une glace pour fermer ladite boîte. Un mouvement horloger à mécanisme musical ou à sonnerie peut être disposé dans un espace de la boîte de montre. L'agencement à rayonnement acoustique est adapté dans la boîte de montre.The invention relates to a musical watch or bell, which is provided with an acoustic radiation arrangement. The watch comprises a watch case, which is constituted at least of a middle and a bottom removably attached to the middle part, and at least one mirror for closing said box. A clockwork movement with a musical mechanism or ringing mechanism can be arranged in a space of the watch case. The acoustic radiation arrangement is adapted in the watch case.

Dans une montre, il peut être prévu un mécanisme de sonnerie pour générer un son ou une musique. Pour ce faire, le timbre de la montre à sonnerie ou le clavier de la montre musicale sont disposés généralement dans la boîte de montre. Ainsi les vibrations du timbre ou des lames du clavier sont transmises aux différentes pièces d'habillage. Ces pièces d'habillage sont par exemple la carrure, la lunette, la glace et le fond de la boîte de montre. Ces grandes pièces d'habillage se mettent à rayonner du son dans l'air sous l'effet des vibrations transmises. 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.In a watch, a striking mechanism may be provided for generating sound or music. To do this, the timbre of the bell watch or the keyboard of the musical watch are generally arranged in the watch case. Thus the vibrations of the timbre or the keyboard blades are transmitted to the different parts of dressing. These pieces of clothing are for example the middle part, the bezel, the ice and the bottom of the watch case. These large pieces of clothing begin to radiate sound in the air under the effect of transmitted vibrations. 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.

Comme pièce ou élément d'habillage additionnel, il peut encore être utilisé une ou plusieurs membranes disposées dans la boîte de montre. Ces membranes sont configurées de telle manière à améliorer le niveau acoustique du son ou de la musique générée. D'autres pièces d'habillage de la montre peuvent aussi être adaptées pour un bon rayonnement sonore notamment à basse fréquence. Cependant, il est difficile d'optimiser le rayonnement acoustique du fond de la boîte de montre, qui reste souvent une pièce d'habillage quasiment inactive acoustiquement.As part or additional element of dressing, it can still be used one or more membranes arranged in the watch case. These membranes are configured in such a way as to improve the acoustic level of the sound or music generated. Other parts of the watch can also be adapted for good sound radiation including low frequency. However, it is difficult to optimize the acoustic radiation from the bottom of the watch case, which often remains a piece of clothing almost inactive acoustically.

Il est à noter que, quand la montre est portée au poignet d'un utilisateur, la vibration de la surface inférieure du fond de la boîte de montre est amortie au contact du poignet. Dans ce cas, la seule solution pour créer un son ou une musique sortant du côté fond de la boîte de montre, consiste à utiliser des ouvertures latérales. Le rayonnement sortant des ouvertures latérales dans le fond reste néanmoins faible, car plusieurs parties entourant lesdites ouvertures sont rigides. De plus, dans le cas d'un fond muni d'une glace pour la vision du mouvement depuis dessous, de la saleté peut pénétrer par les ouvertures du fond et ainsi se déposer sur la surface intérieure de la glace de fond. Un manque d'étanchéité subsiste également avec un tel fond muni de la glace. Cela constitue des inconvénients.It should be noted that, when the watch is worn on the wrist of a user, the vibration of the bottom surface of the bottom of the watch case is dampened on contact with the wrist. In this case, the only solution for creating a sound or music coming out of the bottom side of the watch case is to use side openings. The radiation exiting the lateral openings in the bottom remains low, however, because several parts surrounding said openings are rigid. In addition, in the case of a bottom provided with an ice for the vision of the movement from below, dirt can penetrate through the openings of the bottom and thus be deposited on the inner surface of the bottom ice. A lack of waterproofness also remains with such a bottom provided with ice. This is a disadvantage.

Dans une montre musicale ou à sonnerie, le rendement acoustique, sur la base de la transduction vibro-acoustique complexe des pièces d'habillage, est généralement faible. Pour améliorer et augmenter le niveau acoustique perçu par l'utilisateur de la montre à sonnerie ou musicale, il doit être tenu compte de la matière, de la géométrie et des conditions aux limites des 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.In a musical watch or bell, the acoustic output, based on the complex vibro-acoustic transduction of the trim pieces, is generally low. To improve and increase the acoustic level perceived by the user of the bell or musical watch, the material, geometry and boundary conditions of the 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.

Le contenu fréquentiel du son d'une montre à sonnerie ou musicale doit être riche dans un intervalle de fréquences entre 1 kHz et 6 kHz. Les pièces d'habillage traditionnelles ne permettent pas un rayonnement efficace dans cette bande de fréquences. Comme décrit ci-devant pour pouvoir améliorer encore le rendement vibro-acoustique du mécanisme de sonnerie, une ou plusieurs membranes peuvent être placées dans la boîte de montre. Les membranes peuvent être facilement dimensionnées et configurées pour un rayonnement efficace de la ou des notes générées dans la boîte de montre. Les fréquences des notes générées doivent être proches des modes propres de vibration des membranes pour qu'elles entrent en résonance.The frequency content of the sound of a bell or musical watch must be rich in a frequency range between 1 kHz and 6 kHz. Traditional trim parts do not allow effective radiation in this frequency band. As described above to further improve the vibro-acoustic performance of the striking mechanism, one or more membranes can be placed in the watch case. The membranes can be easily sized and configured for effective radiation of the generated note (s) in the watch case. The frequencies of the generated notes must be close to the natural modes of vibration of the membranes so that they come into resonance.

Les contraintes relatives à l'agencement de membranes acoustiques comme pièce d'habillage, sont généralement en contraste avec les règles de constructions mécaniques permettant de garantir l'étanchéité, ainsi que la résistance mécanique de la montre aux chocs et aux pressions extérieures importantes. Le fond normalement ajouré de la montre à sonnerie ou musicale impose encore que la liaison entre la ou les membranes et le reste du mouvement reste étanche. De plus, une membrane, qui possède une raideur trop faible, ne peut pas garantir une résistance suffisante à une pression externe sans risquer de détériorer le mouvement, ce qui constituent des inconvénients.The constraints relating to the arrangement of acoustic membranes as a covering part, are generally in contrast with the rules of mechanical construction to ensure the seal, as well as the mechanical strength of the watch to shocks and significant external pressures. The normally perforated bottom of the bell or musical watch still imposes that the connection between the membrane (s) and the rest of the movement remains watertight. In addition, a membrane, which has a stiffness too low, can not guarantee sufficient resistance to external pressure without the risk of damaging the movement, which is a drawback.

L'invention a donc pour but de pallier les inconvénients de l'état de la technique susmentionné en fournissant une montre musicale ou à sonnerie, qui est munie d'un agencement à rayonnement acoustique, qui permet d'améliorer le rendement acoustique sur une large bande de fréquences et à garantir également l'étanchéité et la tenue sous une pression externe élevée de la boîte de montre.The invention therefore aims to overcome the disadvantages of the state of the art mentioned above by providing a musical watch or bell, which is provided with an acoustic radiation arrangement, which improves the acoustic performance over a wide range. frequency band and to also guarantee tightness and withstand under high external pressure of the watch case.

A cet effet, l'invention concerne une montre musicale ou à sonnerie, qui est munie d'un agencement à rayonnement acoustique comprenant les caractéristiques définies dans les revendications indépendantes 1 et 2.For this purpose, the invention relates to a musical or striking watch, which is provided with an acoustic radiation arrangement comprising the features defined in the independent claims 1 and 2.

Des formes particulières de la montre musicale ou à sonnerie, qui est munie d'un agencement à rayonnement acoustique, sont définies dans les revendications dépendantes 3 à 18.Particular shapes of the musical or striking watch, which is provided with an acoustic radiation arrangement, are defined in the dependent claims 3 to 18.

Un avantage de la montre musicale ou à sonnerie réside dans le fait qu'avec l'agencement à rayonnement acoustique, il est possible d'intégrer une cavité dans la boîte de montre également avec une glace de fond sans risque de saletés. Un couplage vibro-acoustique efficace est ainsi obtenu entre la cavité et un élément vibrant notamment radialement dans la boîte de montre et de préférence dans le fond.An advantage of the musical or striking watch lies in the fact that with the acoustic radiation arrangement, it is possible to integrate a cavity in the watch case also with a background ice without risk of dirt. An effective vibro-acoustic coupling is thus obtained between the cavity and a vibrating element, especially radially in the watch case and preferably in the bottom.

Grâce à l'agencement à rayonnement acoustique, il est observé une optimisation du son produit notamment par la glace du fond, lorsque la montre n'est pas portée au poignet. De plus, il est constaté une optimisation du son émis par la cavité du fond par les ouvertures latérales et ceci même quand la montre est portée au poignet.Thanks to the arrangement with acoustic radiation, it is observed an optimization of the sound produced in particular by the bottom ice, when the watch is not worn on the wrist. In addition, it is found an optimization of the sound emitted by the bottom cavity through the side openings and this even when the watch is worn on the wrist.

Une augmentation de la durée du son est encore observée avec l'agencement à rayonnement acoustique. Le facteur de qualité acoustique est augmenté par le couplage entre la pièce de support et connexion et la glace de fond avec les degrés de liberté mécaniques. De plus, une partie du bruit généré par le mécanisme est diminué grâce au phénomène d'anti-résonance créé par le couplage vibro-acoustique entre la cavité et la pièce de support et connexion.An increase in the duration of the sound is still observed with the acoustic radiation arrangement. The acoustic quality factor is increased by the coupling between the support and connection piece and the background ice with mechanical degrees of freedom. In addition, a part of the noise generated by the mechanism is reduced by the anti-resonance phenomenon created by the vibro-acoustic coupling between the cavity and the support and connection piece.

Avec la pièce de support et connexion de l'agencement, une étanchéité est assurée et ceci avec la pièce cachée par l'habillage ou lunette du fond. La montre avec l'agencement à rayonnement acoustique peut supporter des pressions élevées, par exemple de l'ordre de 3 bars.With the support piece and connection of the arrangement, a seal is provided and this with the hidden part by the dressing or bezel of the bottom. The watch with the acoustic radiation arrangement can withstand high pressures, for example of the order of 3 bars.

Avec une glace de fond, il est possible de rendre visible le mouvement mécanique même en présence d'une cavité de résonance. Aucune saleté, qui peut entrer dans les ouvertures de la cavité, ne peut se déposer sur la surface interne de la glace du fond. La pièce de support et connexion protège ainsi la glace de la saleté tout en garantissant une bonne étanchéité des composants disposés dans la boîte de montre.With a background glass, it is possible to make visible the mechanical movement even in the presence of a resonance cavity. No dirt, which may enter the openings of the cavity, can be deposited on the inner surface of the bottom ice. The support and connection piece thus protects the ice from dirt while ensuring a good seal of the components arranged in the watch case.

Dans la description suivante, il est fait référence principalement à l'agencement à rayonnement acoustique d'une montre musicale ou à sonnerie, qui est disposé du côté dos de la montre. Cependant il est à noter qu'un tel agencement à rayonnement acoustique peut être prévu également du côté avant de la montre, c'est-à-dire du côté de vision de l'heure affichée comme expliqué ci-après.In the following description, reference is made mainly to the acoustic radiation arrangement of a musical watch or bell, which is arranged on the back side of the watch. However, it should be noted that such an arrangement with acoustic radiation can also be provided on the front side of the watch, that is to say on the viewing side of the time displayed as explained below.

La figure 1 représente une coupe transversale d'une montre musicale ou à sonnerie 1. Cette montre comprend une boîte de montre, qui est constituée principalement d'une carrure 7 et d'un fond 2, et au moins une glace de devant 16 au-dessus d'un cadran de montre pour fermer la boîte de montre. De préférence, la glace de devant 16 est fixée à une lunette 17, qui est reliée étanchement à l'embouchure supérieure de la carrure 7. Un mouvement horloger 10 à mécanisme musical ou à sonnerie est placé dans un espace suffisant dans la boîte de montre. La montre comprend encore un agencement à rayonnement acoustique, qui peut être réalisé dans le fond 2 de la boîte de montre comme expliqué ci-après.The figure 1 represents a cross-section of a musical watch or bell 1. This watch includes a watch case, which consists mainly of a middle 7 and a bottom 2, and at least one front glass 16 above a watch dial to close the watch case. Preferably, the front lens 16 is attached to a bezel 17, which is connected sealingly to the upper mouth of the caseband 7. A watchmaker movement 10 with a musical mechanism or striking is placed in a sufficient space in the watch case . The watch further comprises an acoustic radiation arrangement, which can be realized in the bottom 2 of the watch case as explained below.

Comme il peut être vu plus précisément sur les figures 2 et 3, cet agencement à rayonnement acoustique comprend une pièce de support et connexion 5, qui est fixée dans le fond 2 de la boîte. Cette pièce de support et connexion 5 est disposée entre une lunette de fond 12 et une glace de fond 6. La pièce de support et connexion est composée de deux parties rigides 5a, 5b, qui sont maintenues respectivement en contact d'une paroi intérieure de la lunette de fond 12 et d'une surface latérale ou de bordure de la glace de fond 6.As it can be seen more precisely on figures 2 and 3 this acoustic radiation arrangement comprises a support and connection piece 5, which is fixed in the bottom 2 of the box. This piece of support and connection 5 is disposed between a bottom window 12 and a bottom window 6. The support and connection piece is composed of two rigid parts 5a, 5b, which are respectively held in contact with a wall interior of the bottom window 12 and a side surface or border of the bottom window 6.

Ces première et seconde parties rigides 5a et 5b peuvent être de préférence collées d'une part à une paroi intérieure de la lunette de fond 12 et d'autre part à la glace de fond 6. La première partie rigide 5a peut aussi être fixée à la paroi intérieure de la lunette de fond 12 par simple frottement ou être vissée. Par contre la glace 6 n'est pas collée à l'ouverture de fond de la lunette de fond 12 de manière à permettre une vibration de la glace 6 dans un mode de vibration de type piston. La pièce de support et connexion 5 est ainsi fixée à la lunette de fond 12 et à la glace 6 tout en garantissant une bonne étanchéité de l'intérieur de la boîte de montre.These first and second rigid portions 5a and 5b may preferably be bonded on the one hand to an inner wall of the bottom window 12 and on the other hand to the bottom window 6. The first rigid part 5a may also be attached to the inner wall of the bottom bezel 12 by simple friction or be screwed. By against the ice 6 is not glued to the bottom opening of the bottom window 12 so as to allow a vibration of the ice 6 in a piston type vibration mode. The support and connection piece 5 is thus fixed to the bottom window 12 and to the window 6 while ensuring a good seal of the inside of the watch case.

La pièce de support et connexion 5 comprend encore une partie intermédiaire 5c, qui est de préférence flexible et de très faible épaisseur. Cette partie intermédiaire 5c relie les deux parties rigides 5a et 5b. De préférence les parties 5a, 5b, 5c ne forment qu'une seule pièce monobloc réalisée dans un même matériau. Cependant il peut aussi être envisagé que les parties 5a, 5b et 5c sont réalisées séparément et assemblées par la suite pour former la pièce de support et connexion 5. Cette partie intermédiaire flexible 5c permet la vibration de la glace de fond à basses fréquences, si la montre musicale ou à sonnerie n'est pas portée au poignet d'un utilisateur.The support and connection piece 5 further comprises an intermediate portion 5c, which is preferably flexible and very thin. This intermediate portion 5c connects the two rigid parts 5a and 5b. Preferably the parts 5a, 5b, 5c form a single piece made of the same material. However it can also be envisaged that the parts 5a, 5b and 5c are made separately and subsequently assembled to form the support part and connection 5. This flexible intermediate portion 5c allows the vibration of the bottom ice at low frequencies, if the musical or striking watch is not worn on the wrist of a user.

La lunette de fond 12 comprend encore plusieurs ouvertures latérales 3 pour le passage d'au moins un son généré par le mécanisme musical ou à sonnerie. Ces ouvertures latérales 3 sont de préférence orientées dans le plan de la montre. Il peut être prévu par exemple entre 2 et 8 ouvertures comme montré à la figure 2, qui sont régulièrement réparties ou espacées sur le pourtour de la lunette de fond 12. Une cavité 4 est définie entre la pièce de support et connexion 5 et les ouvertures 3 de la lunette de fond 12, qui définissent des conduites vers l'extérieur de ladite cavité acoustique. Comme la pièce de support et connexion 5 est de préférence réalisée sous la forme de bague, la cavité annulaire 4 est définie sur tout le pourtour de la pièce de support et connexion 5 en regard d'une surface intérieure de la lunette de fond 12.The bottom window 12 further comprises several lateral openings 3 for the passage of at least one sound generated by the musical mechanism or ringing. These lateral openings 3 are preferably oriented in the plane of the watch. It can be provided for example between 2 and 8 openings as shown in FIG. figure 2 , which are regularly distributed or spaced around the periphery of the bottom window 12. A cavity 4 is defined between the support and connection piece 5 and the openings 3 of the bottom window 12, which define outward lines of said acoustic cavity. Since the support and connection piece 5 is preferably made in the form of a ring, the annular cavity 4 is defined all around the support piece and connection 5 facing an inner surface of the bottom window 12.

Dans une variante de réalisation, la lunette de fond 12 peut comprendre plusieurs ouvertures latérales 3 disposées sur un secteur de la lunette de fond. Ce secteur peut être de dimension inférieure ou égale à la moitié de la lunette de fond 12. Dans le cas d'une lunette de fond de forme circulaire, le secteur angulaire s'étend sur une portion de la lunette de fond inférieure ou égale à 180°. Les ouvertures latérales 3 de la lunette de fond 12 peuvent être orientées perpendiculairement à la partie intermédiaire flexible 5c, si cette partie intermédiaire est dans le plan avec la première partie rigide 5a, ou à la glace de fond 6.In an alternative embodiment, the bottom window 12 may include a plurality of lateral openings 3 disposed on a sector of the bottom window. This sector may be smaller than or equal to half of the bottom window 12. In the case of a circular bottom bezel, the angular sector extends over a portion of the bottom bezel less than or equal to 180 °. The lateral openings 3 of the bottom telescope 12 can be oriented perpendicularly to the flexible intermediate part 5c, if this intermediate part is in the plane with the first rigid part 5a, or to the base plate 6.

Il est encore à noter que l'épaisseur de la partie intermédiaire 5c dépend de la matière utilisée pour la pièce de support et connexion 5. Dans le cas d'une pièce de support et connexion 5 réalisée en or rouge et pour une fréquence de résonance du premier mode propre à environ 7'000 Hz, l'épaisseur de la partie intermédiaire flexible 5c peut être comprise entre 0.1 et 0.3 mm et de préférence de l'ordre de 0.14 mm. Cette pièce de support et connexion 5 peut aussi être réalisée en or jaune ou gris, en platine ou en verre métallique. Plus la partie flexible 5c est fine et plus la fréquence du premier mode propre est basse. Le diamètre de la pièce de support et connexion 5 peut être compris généralement entre 20 et 40 mm et correspond à peu près au diamètre intérieur de la lunette de fond 12.It should also be noted that the thickness of the intermediate portion 5c depends on the material used for the support and connection piece 5. In the case of a support piece and connection 5 made in red gold and for a resonance frequency of the first clean mode at about 7'000 Hz, the thickness of the flexible intermediate portion 5c may be between 0.1 and 0.3 mm and preferably of the order of 0.14 mm. This piece of support and connection 5 can also be made of yellow or gray gold, platinum or metal glass. The more the flexible part 5c is fine, the lower the frequency of the first clean mode. The diameter of the support and connection piece 5 may be generally between 20 and 40 mm and corresponds approximately to the inside diameter of the bottom window 12.

Comme montré plus en détail à la figure 3, la partie intermédiaire 5c est disposée dans un même plan que la première partie rigide 5a, et également parallèle à la glace de fond 6. La première partie rigide 5a est fixée sur un bord intérieur et une paroi intérieure de la lunette de fond 12 et en partie dans une portion supérieure des ouvertures cylindriques 3. Par contre, la partie intermédiaire 5c est reliée à une portion perpendiculaire de la seconde partie rigide 5b. Ainsi, la pièce de support et connexion 5 assure un couplage vibro-acoustique entre la cavité acoustique 4 et la partie intermédiaire flexible 5c en tant que membrane vibrante en forme de couronne circulaire.As shown in more detail in figure 3 the intermediate part 5c is arranged in the same plane as the first rigid part 5a, and also parallel to the bottom plate 6. The first rigid part 5a is fixed on an inner edge and an inner wall of the bottom window 12 and partly in an upper portion of the cylindrical openings 3. On the other hand, the intermediate portion 5c is connected to a perpendicular portion of the second rigid portion 5b. Thus, the support piece and connection 5 provides a vibro-acoustic coupling between the acoustic cavity 4 and the part flexible intermediate 5c as a vibrating membrane in the shape of a circular crown.

Il est encore possible de prévoir que la partie intermédiaire 5c peut être disposée dans un même plan que la seconde partie rigide 5b et sensiblement perpendiculaire à la première partie rigide 5a de la pièce de support et connexion 5 ou de la glace de fond 6. Il peut aussi être prévu une première portion de la partie intermédiaire 5c, qui est disposée dans un même plan que la première partie rigide 5a et une seconde portion, qui est disposée dans un même plan que la seconde partie rigide 5b.It is also possible to provide that the intermediate portion 5c may be disposed in the same plane as the second rigid portion 5b and substantially perpendicular to the first rigid portion 5a of the support and connecting piece 5 or the bottom ice 6. It may also be provided a first portion of the intermediate portion 5c, which is disposed in the same plane as the first rigid portion 5a and a second portion, which is disposed in the same plane as the second rigid portion 5b.

La lunette de fond 12 comprend encore une bordure de fixation 12a pour sa fixation à la partie basse de la carrure 7 comme montré à la figure 1. Une fois la lunette de fond 12 fixée par sa bordure de fixation 12a à la partie basse de la carrure 7, la première partie rigide 5a de la pièce de support et connexion 5 est en contact direct avec la carrure 7. La vibration de la carrure 7 met ainsi directement en vibration la pièce de support et connexion 5 grâce à sa partie intermédiaire flexible 5c. Cela permet de maximiser le transfert vibratoire entre un générateur de vibration du mécanisme musical ou à sonnerie et un élément rayonnant, qui peut être la glace de fond 6 et/ou la cavité acoustique 4.The bottom bezel 12 further comprises a fastening edge 12a for attachment to the lower part of the caseband 7 as shown in FIG. figure 1 . Once the bottom bezel 12 fixed by its fastening edge 12a to the lower part of the middle part 7, the first rigid part 5a of the support and connection piece 5 is in direct contact with the middle part 7. The vibration of the middle part 7 thus directly vibrates the support part and connection 5 with its flexible intermediate portion 5c. This makes it possible to maximize the vibratory transfer between a vibration generator of the musical or striking mechanism and a radiating element, which may be the base ice 6 and / or the acoustic cavity 4.

Il est encore à noter que la vibration axiale et radiale de la pièce de support et connexion 5 produit deux effets. Un premier effet est la mise en vibration de la glace de fond 6 selon des modes de vibration de type piston sans déformation de ladite glace de fond. Un second effet est la modulation du volume de la cavité acoustique 4, dont une des parois est la partie intermédiaire flexible 5c, qui active un mode de résonance de ladite cavité 4. Ce mode de résonance de la cavité peut être actif acoustiquement avec un rayonnement vers l'extérieur de la montre par les ouvertures 3, ou inactif acoustiquement en jouant un rôle d'amortisseur en fonction de la fréquence de la vibration.It should also be noted that the axial and radial vibration of the support and connection piece 5 produces two effects. A first effect is the vibration of the bottom ice 6 according to piston-type vibration modes without deformation of said bottom ice. A second effect is the modulation of the volume of the acoustic cavity 4, one of whose walls is the flexible intermediate part 5c, which activates a resonance mode of said cavity 4. This mode of resonance of the cavity can be acoustically active with a radiation towards the outside of the watch through the openings 3, or acoustically inactive by acting as a shock absorber as a function of the frequency of the vibration.

Avec l'agencement à rayonnement acoustique dans le fond 2, les modes réels de vibration et les modes acoustiques, qui sont les ondes de pression, ne coïncident pas avec les modes individuels de la pièce de support et connexion 5 et de la glace de fond 6. Les modes réels de vibration et les modes acoustiques ne coïncident également pas avec les modes purement acoustiques de la cavité 4. Les modes couplés ayant une contribution principale de vibration interviennent comme des modes d'amortissement du son, alors que les modes ayant une contribution principale de modulation de pression acoustique interviennent comme des modes de rayonnement amplifié.With the acoustic radiation arrangement in the bottom 2, the actual modes of vibration and the acoustic modes, which are the waves of pressure, do not coincide with the individual modes of the support and connection piece 5 and the background glass 6. The actual modes of vibration and the acoustic modes also do not coincide with the purely acoustic modes of the cavity 4. The modes Coupled with a main vibration contribution occur as sound damping modes, while modes having a main contribution of sound pressure modulation intervene as amplified radiation modes.

Dans la figure 4, il est représenté une comparaison des réponses vibratoires fréquentielles d'un fond standard et d'un fond à couplage vibro-acoustique avec l'agencement à rayonnement acoustique. Cet agencement à rayonnement acoustique est optimisé comme décrit ci-dessus en référence aux figures 1 à 3. La pièce de support et connexion 5 de l'agencement à rayonnement acoustique peut être réalisée en or rouge.In the figure 4 a comparison of the frequency vibratory responses of a standard background and a vibro-acoustically coupled background with the acoustic radiation arrangement is shown. This acoustic radiation arrangement is optimized as described above with reference to Figures 1 to 3 . The support and connection piece 5 of the acoustic radiation arrangement can be made of red gold.

Dans le cas d'un fond standard selon la courbe b, l'accélération axiale de la glace de fond présente uniquement deux résonances. La fréquence de la première résonance est à 8 kHz. Par contre dans le cas du fond à couplage vibro-acoustique de l'invention selon la courbe a, la fréquence de la première résonance est réduite d'environ 1 kHz pour se situer à 7 kHz. Le facteur de qualité est augmenté avec une largeur de pic réduite, ce qui correspond à une augmentation significative de la durée de la vibration, et donc du son généré. Selon la courbe a du fond à couplage vibro-acoustique de l'invention, il y a encore une anti-résonance, c'est-à-dire un minimum local, qui est introduite à environ 15 kHz. Cela permet d'avoir la suppression des composantes du bruit du mécanisme, qui sont présentes dans cet intervalle de fréquences.In the case of a standard bottom according to the curve b, the axial acceleration of the bottom ice has only two resonances. The frequency of the first resonance is at 8 kHz. On the other hand, in the case of the vibroacoustic coupling back of the invention according to curve a, the frequency of the first resonance is reduced by approximately 1 kHz to be at 7 kHz. The quality factor is increased with a reduced peak width, which corresponds to a significant increase in the duration of the vibration, and therefore the sound generated. According to the curve a of the vibro-acoustic coupling of the invention, there is still an anti-resonance, that is to say a local minimum, which is introduced at about 15 kHz. This allows the removal of the noise components of the mechanism, which are present in this frequency range.

Il est à noter que grâce à l'agencement à rayonnement acoustique représenté aux figures 1 à 3, la saleté, qui peut entrer à travers les ouvertures latérales 3 de la cavité 4, ne peut pas se déposer sur la surface interne de la glace de fond 6. La pièce de support et connexion 5 protège complètement la glace de fond de toute saleté venant de l'extérieur et garantit l'étanchéité de l'intérieur de la boîte de montre.It should be noted that thanks to the acoustic radiation arrangement shown in Figures 1 to 3 , the dirt, which can enter through the side openings 3 of the cavity 4, can not be deposited on the inner surface of the bottom window 6. The support piece and connection 5 protects completely the bottom ice of any dirt coming from the outside and guarantees the tightness of the inside of the box of watch.

Avec la glace de fond 6, il est possible de rendre visible le mouvement 10 dans la boîte de montre. Cette propriété est généralement difficile à obtenir pour un fond actif et optimisé acoustiquement avec une cavité de résonance.With the background glass 6, it is possible to make the movement 10 visible in the watch case. This property is generally difficult to obtain for an active background and acoustically optimized with a resonance cavity.

Selon une variante de réalisation, les ouvertures latérales 3 de la cavité acoustique 4 peuvent être partiellement fermées par des membranes à petits trous. Les petits trous de ces membranes permettent le passage de l'air tout en protégeant l'intérieur de la cavité de l'accumulation de saleté.According to an alternative embodiment, the lateral openings 3 of the acoustic cavity 4 may be partially closed by membranes with small holes. The small holes of these membranes allow the passage of air while protecting the interior of the cavity from the accumulation of dirt.

Pour réaliser l'agencement à rayonnement acoustique présenté aux figures 1 à 3 dans le fond 2 de la boîte de montre, les matériaux envisagés sont de préférence des matériaux métalliques ou des verres métalliques. Il peut s'agir de l'or gris, jaune ou rouge pour la lunette de fond 12, de l'or gris, jaune ou rouge, du platine et des verres métalliques pour la pièce de support et connexion 5.To achieve the acoustic radiation arrangement presented to Figures 1 to 3 in the bottom 2 of the watch case, the materials envisaged are preferably metallic materials or metallic glasses. It may be gray, yellow or red gold for the base telescope 12, gray, yellow or red gold, platinum and metallic glasses for the support and connection piece 5.

L'agencement à rayonnement acoustique peut aussi être réalisé du côté de la glace 16 de la montre 1 représentée à la figure 1. Dans ce cas, la pièce de support et connexion est reliée entre la partie supérieure de la carrure 7 ou la lunette 17 et la glace de devant 16. Des ouvertures latérales peuvent encore être prévues entre la carrure 7 ou la lunette 17 et la pièce de support et connexion 5. Une cavité annulaire 4 est formée entre la pièce de support et connexion et les ouvertures de la carrure 7 ou la lunette 17. Une première partie rigide 5a peut être fixée à une paroi intérieure de la carrure ou de la lunette, alors qu'une seconde partie rigide 5b peut être fixée à une surface latérale ou de bordure de la glace 16. La partie intermédiaire 5c peut être configurée et disposée par rapport aux parties rigides 5a et 5b comme précisé en référence aux figures 1 à 3.The acoustic radiation arrangement can also be made on the ice side 16 of the watch 1 shown in FIG. figure 1 . In this case, the support and connection piece is connected between the upper part of the middle part 7 or the bezel 17 and the front glass 16. Lateral openings may also be provided between the caseband 7 or the bezel 17 and the piece of support and connection 5. An annular cavity 4 is formed between the support and connection piece and the openings of the middle part 7 or the bezel 17. A first rigid part 5a can be fixed to an inner wall of the middle part or the bezel, while a second rigid portion 5b can be attached to a side or edge surface of the lens 16. The intermediate portion 5c can be configured and arranged with respect to the rigid portions 5a and 5b as specified with reference to the Figures 1 to 3 .

Il est encore à noter que les ouvertures latérales 3 de la carrure 7 ou de la lunette 17 peuvent aussi être réparties sur un secteur de la carrure 7 ou de la lunette 17. Ce secteur peut être de dimension inférieure ou égale à la moitié du pourtour de la carrure 7 ou de la lunette 17. Les ouvertures latérales 3 de la carrure 7 ou de la lunette 17 peuvent être orientées perpendiculairement à la glace 16.It should also be noted that the lateral openings 3 of the middle part 7 or the bezel 17 can also be distributed over a sector of the middle part 7 or of the telescope 17. This sector may be smaller than or equal to half the circumference of the caseband 7 or the bezel 17. The lateral openings 3 of the caseband 7 or the bezel 17 may be oriented perpendicularly to the ice 16.

A partir de la description qui vient d'être faite, plusieurs variantes de réalisation d'une montre musicale ou à sonnerie ou musicale ayant un agencement à rayonnement acoustique peuvent être conçues par l'homme du métier sans sortir du cadre de l'invention définie par les revendications. Il peut être prévu un agencement à rayonnement acoustique du côté du fond de la boîte de montre et du côté de la glace avant de la montre. Les ouvertures latérales peuvent être de différentes dimensions et de forme différente de la forme cylindrique. La partie intermédiaire flexible, qui est annulaire peut présenter une ondulation. La pièce de support et connexion peut être obtenue par moulage ou emboutissage d'une préforme. Il peut encore être prévu une ou plusieurs membranes acoustiques entre le mécanisme musical ou à sonnerie et l'agencement à rayonnement acoustique.From the description that has just been given, several variants of a musical watch or ringtone or musical having an acoustic radiation arrangement can be designed by the skilled person without departing from the scope of the invention defined by the claims. An acoustic radiation arrangement may be provided on the bottom side of the watch case and the front ice side of the watch.
