Arrière-plan de l'inventionBackground of the invention

Une bonne émission sonore est toujours un problème difficile à résoudre pour une montre musicale, dans la mesure où les organes rayonnants ne doivent pas gêner l'utilisateur de la montre, ni nuire à l'étanchéité de la montre, et où il faut amortir le moins possible pour faire rayonner la vibration des timbres, gongs, claviers, cloches ou similaires, de façon bien audible par l'utilisateur, avec un son non altéré par des vibrations parasites générées par d'autres constituants de la montre, tels que le mécanisme d'activation de la sonnerie ou du jeu musical, et/ou le mécanisme de régulation de la sonnerie ou du jeu musical, et/ou le mouvement d'horlogerie, ou autre.Good sound emission is always a difficult problem to solve for a musical watch, insofar as the radiating elements must not disturb the user of the watch, nor harm the water resistance of the watch, and where it is necessary to dampen the less possible to radiate the vibration of gongs, gongs, keyboards, bells or similar, in a way that is clearly audible to the user, with a sound not altered by parasitic vibrations generated by other components of the watch, such as the mechanism for activating the ringtone or the musical game, and/or the mechanism for regulating the ringtone or the musical game, and/or the clockwork movement, or other.

Description détaillée des modes de réalisation préférésDetailed description of the preferred embodiments

L'invention concerne une boîte de montre musicale 100 comportant au moins un ensemble couvercle 1. Cet ensemble couvercle 1 comporte, d'une part une lunette 2, et d'autre part au moins une glace 3 ou un fond 5.The invention relates to a musical watch case 100 comprising at least one cover assembly 1. This cover assembly 1 comprises, on the one hand a bezel 2, and on the other hand at least one glass 3 or a base 5.

On comprend que la boîte 100 peut comporter un ensemble couvercle 1 supérieur avec une lunette 2 et une glace 3, tel qu'illustré par l'ensemble des figures, ou peut comporter un ensemble couvercle 1 inférieur avec une lunette 2 et un fond 5, ou encore à la fois un ensemble couvercle 1 supérieur avec une lunette 2 et une glace 3, et un ensemble couvercle 1 inférieur avec une lunette 2 et un fond 5.We understand that the box 100 may include an upper lid assembly 1 with a bezel 2 and a glass 3, as illustrated by all the figures, or may include a lower lid assembly 1 with a bezel 2 and a bottom 5, or both an upper cover assembly 1 with a bezel 2 and a glass 3, and a lower cover assembly 1 with a bezel 2 and a bottom 5.

Par « montre musicale » on entend une montre qui comporte un mécanisme de sonnerie et/ou un mécanisme de réveil ou d'alarme et/ou un mécanisme de boîte à musique.By “musical watch” we mean a watch which includes a striking mechanism and/or an alarm or alarm mechanism and/or a music box mechanism.

La boîte 100 comporte encore un cercle d'encageage 4, agencé pour porter un mouvement et/ou un mécanisme, et une carrure 10.The box 100 also includes a casing circle 4, arranged to carry a movement and/or a mechanism, and a middle part 10.

Cette carrure 10 comporte une première surface 11 pour la réception en appui de l'ensemble couvercle 1, et une surface médiane 14 pour la réception en appui du cercle d'encageage 4.This middle part 10 comprises a first surface 11 for receiving the cover assembly 1 in support, and a middle surface 14 for receiving the caging circle 4 in support.

Cette carrure 10, ou bien constitue un fond de la boîte 100, ou bien comporte une deuxième surface 15 pour la réception en appui d'un ensemble couvercle inférieure comportant une lunette 2 et un fond 5, ou pour la réception directe d'un fond 5. Quand l'ensemble couvercle 1 qui est en appui sur la première surface 11 comporte une lunette 2 et un fond 5, la deuxième surface 15 peut naturellement êtreadaptée à la réception d'une glace 3, ou d'un autre ensemble couvercle 1 comportant une lunette 2 et une glace 3.This middle part 10, either constitutes a bottom of the box 100, or comprises a second surface 15 for receiving in support of a lower cover assembly comprising a bezel 2 and a bottom 5, or for directly receiving a bottom 5. When the cover assembly 1 which is supported on the first surface 11 comprises a bezel 2 and a bottom 5, the second surface 15 can naturally be adapted to receive a glass 3, or another cover assembly 1 comprising a bezel 2 and a glass 3.

Plus particulièrement, la boîte 100 comporte un fond 5 qui est transparent.More particularly, the box 100 has a bottom 5 which is transparent.

La boîte 100 comporte au moins un organe résonant, notamment un timbre 6 solidaire de la carrure 10, c'est-à-dire rapporté et fixé sur la carrure 10, ou encore monobloc avec la carrure 10, et qui comporte une partie résonante qui est distincte des parois de la carrure 10. L'organe résonant peut prendre d'autres formes qu'un timbre, sans modifier l'essence de l'invention. Par « timbre » 6 on entend ainsi tout organe résonant usuel en horlogerie : timbre, gong, clavier, cloche, ou similaire.The box 100 comprises at least one resonant member, in particular a gong 6 integral with the middle part 10, that is to say attached and fixed on the middle part 10, or else in one piece with the middle part 10, and which comprises a resonant part which is distinct from the walls of the middle part 10. The resonant member can take forms other than a gong, without modifying the essence of the invention. By “timbre” 6 we therefore mean any resonant organ usual in watchmaking: gong, gong, keyboard, bell, or the like.

La carrure 10 porte l'ensemble couvercle 1 par au moins une patte 7, que comporte la lunette 2 ou la carrure 10, et qui est agencée pour permettre la vibration et le rayonnement de l'ensemble couvercle 1 à des fréquences comprises entre 4 kHz et 6 kHz.The middle part 10 carries the cover assembly 1 by at least one tab 7, which includes the bezel 2 or the middle part 10, and which is arranged to allow the vibration and radiation of the cover assembly 1 at frequencies between 4 kHz and 6 kHz.

Plus particulièrement encore, toutes les pattes 7 de la boîte 100 sont à l'extérieur de la carrure 10, vers la périphérie de la boîte 100, du côté opposé à la chambre intérieure 17 par rapport à la carrure 10.In a variant, the middle part 10 comprises at least one substantially annular peripheral wall 16 defining an interior chamber 17 extending around the casing circle 4 arranged to support a watch movement and/or a watch mechanism, and in the case 100 has tabs 7 outside the middle part 10, towards the periphery of the box 100, on the side opposite the interior chamber 17 relative to the middle part 10. Even more particularly, all the tabs 7 of the box 100 are outside the middle part 10, towards the periphery of the box 100, on the side opposite the interior chamber 17 with respect to the middle part 10.

Selon un mode de réalisation particulier, la boîte comporte une pluralité de telles pattes 7 comportant chacune, entre la carrure 10 et la lunette 2, une lame fine médiane 74 élastique sensiblement rectiligne, et les directions de toutes les lames fines médianes 74 élastiques sensiblement rectilignes sont de même inclinaison par rapport à un même axe de référence central.According to a particular embodiment, the box comprises a plurality of such tabs 7 each comprising, between the middle part 10 and the bezel 2, a thin median elastic blade 74 substantially rectilinear, and the directions of all the thin median elastic blades 74 substantially rectilinear are of the same inclination relative to the same central reference axis.

Selon un mode de réalisation particulier, toutes les lames fines médianes 74 élastiques sensiblement rectilignes sont disposées sur une même surface de révolution autour du même axe de référence central.According to a particular embodiment, all the thin, substantially rectilinear elastic middle blades 74 are arranged on the same surface of revolution around the same central reference axis.

Dans une variante particulière, cette surface de révolution est un cône.In a particular variant, this surface of revolution is a cone.

Dans une autre variante particulière, cette surface de révolution est un cylindre.In another particular variant, this surface of revolution is a cylinder.

Dans une autre variante encore, toutes les lames fines médianes 74 élastiques sensiblement rectilignes sont disposées dans un même plan ou parallèlement à un même plan.In yet another variant, all the substantially rectilinear elastic middle thin blades 74 are arranged in the same plane or parallel to the same plane.

Selon une caractéristique particulière, la carrure 10 comporte, autour d'une paroi périphérique 16 sensiblement annulaire définissant une chambre intérieure 17 s'étendant autour du cercle d'encageage 4, et autour de toutes les pattes 7 que comporte la boîte 100, un anneau résonateur 8, qui est rapporté sur la carrure 10 ou qui forme une lèvre de la carrure 10. Cet anneau résonateur 8 est en tout point distant de la lunette 2 et des pattes 7, et forme avec la paroi périphérique 16 une cavité rayonnante extérieure 18. Plus particulièrement, l'anneau résonateur 8 est d'une épaisseur inférieure à celle de chaque patte 7, et est en alliage d'or et/ou de platine et/ou de titane.According to a particular characteristic, the middle part 10 comprises, around a substantially annular peripheral wall 16 defining an interior chamber 17 extending around the caging circle 4, and around all the lugs 7 which the box 100 comprises, a ring resonator 8, which is attached to the middle part 10 or which forms a lip of the middle part 10. This resonator ring 8 is at every point distant from the bezel 2 and the lugs 7, and forms with the peripheral wall 16 an exterior radiating cavity 18 More particularly, the resonator ring 8 is of a thickness less than that of each leg 7, and is made of gold and/or platinum and/or titanium alloy.

De façon avantageuse et particulière, au moins un des constituants métalliques de la boîte 100, et plus particulièrement l'ensemble des constituants métalliques de la boîte 100, à l'exception des glaces et joints d'étanchéité, est réalisé dans un matériau permettant d'obtenir une fréquence critique de rayonnement inférieure ou égale à celle obtenue avec une exécution en alliage d'or ou en or. Plus particulièrement, la carrure 10, la lunette 2, et le fond 5 quand la boîte 100 comporte un fond 5 métallique, sont réalisés dans le même alliage. Plus particulièrement encore, cet alliage est un alliage de titane, convenant bien aux contraintes mécaniques et aux contraintes d'étanchéité usuelles à au moins 5 bar, et dont le pouvoir rayonnant est supérieur à celui de l'or, ce choix permettant d'obtenir une fréquence propre dans la fourchette recherchée de 4 kHz à 6 kHz. Dans une variante particulière, cet alliage est du « titane grade 5 », comportant 90% de titane, 6% d'aluminium, et 4% de vanadium; dans une autre variante cet alliage est un alliage précieux de titane, et notamment de titane et d'or, selon l'une des demandes de brevet PCT/EP2015/080211 et PCT/EP2015/080270 au nom de Montres Breguet SA. Plus particulièrement on choisit un alliage titrable.Advantageously and particularly, at least one of the metallic constituents of the box 100, and more particularly all of the metallic constituents of the box 100, with the exception of the glasses and seals, is made of a material allowing obtain a critical frequency of radiation less than or equal to that obtained with an execution in gold alloy or gold. More particularly, the middle part 10, the bezel 2, and the back 5 when the box 100 has a metal back 5, are made of the same alloy. Even more particularly, this alloy is a titanium alloy, well suited to mechanical stresses and usual sealing stresses at at least 5 bar, and whose radiating power is greater than that of gold, this choice making it possible to obtain a natural frequency in the desired range of 4 kHz to 6 kHz. In a particular variant, this alloy is “grade 5 titanium”, comprising 90% titanium, 6% aluminum, and 4% vanadium; in another variant this alloy is a precious alloy of titanium, and in particular of titanium and gold, according to one of the patent applications PCT/EP2015/080211 And PCT/EP2015/080270 on behalf of Montres Breguet SA. More particularly, we choose a titratable alloy.
