Description

Domaine techniqueTechnical area

La présente invention se rapporte au domaine de l'horlogerie. Elle concerne, plus particulièrement, une pièce d'horlogerie comprenant un mécanisme de sonnerie.The present invention relates to the field of watchmaking. It relates, more particularly, a timepiece comprising a striking mechanism.

Etat de la techniqueState of the art

Des pièces d'horlogerie portables, telles que des montres de poche et des montres bracelets, peuvent être munies d'un mécanisme de sonnerie qui fournit un signal acoustique pour indiquer l'heure à la demande et/ou en passant (montres à répétition), ou à un moment prédéterminé par l'utilisateur (montres-réveils). À cet effet, elles comportent typiquement au moins un timbre en forme de fil ou de cloche, qui est frappé par un marteau afin d'émettre des sons audibles.Portable timepieces, such as pocket watches and wristwatches, can be equipped with a striking mechanism that provides an acoustic signal to indicate the time on demand and / or by the way (repeating watches) , or at a predetermined time by the user (clock-clocks). For this purpose, they typically include at least one wire or bell-shaped stamp, which is struck by a hammer to emit audible sounds.

Puisque les montres portables sont typiquement étanches afin d'éviter la pénétration d'humidité et de poussières vers leur intérieur, elles incorporent typiquement une membrane étanche agencée côté fond entre le mouvement et le fond, cette membrane assurant à la fois l'étanchéité ainsi que la transmission vers l'extérieur des sons produits par le ou les timbres. Cependant, cette transmission est limitée en ce qui concerne non seulement l'intensité sonore transmise, mais aussi au niveau de sa qualité.Since portable watches are typically sealed to prevent the ingress of moisture and dust to their interior, they typically incorporate a waterproof membrane arranged on the bottom side between the movement and the bottom, this membrane ensuring both the seal as well as the transmission to the outside of the sounds produced by the stamp (s). However, this transmission is limited as regards not only the transmitted loudness, but also in terms of its quality.

Diverses solutions ont été proposées afin de surmonter ce défaut.Various solutions have been proposed to overcome this defect.

Le document CH285202 décrit une pièce d'horlogerie à sonnerie dans laquelle la membrane est en contact avec le fond par l'intermédiaire d'un plot ou similaire, afin de transmettre des vibrations au fond. Ce dernier étant en contact avec le poignet du porteur ou, si la pièce est posée, avec la surface sur laquelle elle repose, ce contact amorti la vibration du fond. Le résultat de cet amortissement est que les vibrations du fond sont étouffées, ce qui diminue l'intensité sonore ainsi que la qualité du son.The document CH285202 describes a striking timepiece in which the membrane is in contact with the bottom via a pad or the like, in order to transmit vibrations to the bottom. The latter being in contact with the wearer's wrist or, if the piece is placed, with the surface on which it rests, this touch dampens the vibration of the bottom. The result of this damping is that the vibrations of the bottom are muffled, which decreases the loudness as well as the quality of the sound.

Le document EP3220210 dévoile une montre à sonnerie dans laquelle l'ensemble glace-lunette est agencé pour vibrer, et que l'interstice entre la lunette et la carrure est rendue étanche par l'intermédiaire d'un ou plusieurs joints agencés afin de favoriser la transmission de son. L'ensemble glace-lunette est relativement lourd, et donc sa fréquence naturelle de vibration est relativement basse. Ceci est loin d'être d'optimal pour la transmission du son, et l'agencement de joints latéraux est relativement fragile.The document EP3220210 reveals a striking watch in which the ice-glasses assembly is arranged to vibrate, and that the gap between the bezel and the middle part is sealed by means of one or more joints arranged in order to promote the transmission of sound . The ice-glasses assembly is relatively heavy, and therefore its natural vibration frequency is relatively low. This is far from optimal for sound transmission, and the arrangement of side seals is relatively fragile.

Le document CH712080 décrit une pièce d'horlogerie à sonnerie comprenant des parties creuses, comme par exemple des tubes ou des cavités, qui débouchent latéralement à l'extérieur de la carrure afin de transmettre des sons. Ces agencements sont complexes et encombrants, ce qui complique la construction de la carrure et occupe de l'espace à l'intérieur du boitier. Par ailleurs, l'étanchéité de la montre est également rendue plus difficile à assurer, et les cavités sont susceptibles d'accumuler de la poussière ainsi que des saletés.The document CH712080 describes a striking timepiece comprising hollow portions, such as tubes or cavities, which open laterally outside the middle to transmit sounds. These arrangements are complex and cumbersome, which complicates the construction of the middle part and takes up space inside the case. In addition, the waterproofness of the watch is also made more difficult to ensure, and the cavities are likely to accumulate dust and dirt.

Le document EP2367078 décrit une montre à sonnerie dans laquelle un support annulaire, qui porte la platine, est tenu en sandwich entre la carrure et le fond, la bordure de la membrane étant interposée entre le support et le fond. L'interaction entre le support annulaire et la membrane s'effectue donc à la périphérie de cette dernière, ce qui n'est pas optimal pour la transmission sonore et limite l'amplitude de vibration pouvant être atteinte par la membrane.The document EP2367078 describes a striking watch in which an annular support, which carries the plate, is sandwiched between the middle and the bottom, the edge of the membrane being interposed between the support and the bottom. The interaction between the annular support and the membrane is therefore performed at the periphery of the latter, which is not optimal for the sound transmission and limits the amplitude of vibration that can be reached by the membrane.

Le document EP2942675 décrit une montre dans laquelle le talon qui porte le timbre coopère avec une membrane, des ouvertures latérales étant prévues dans le fond de la pièce. À nouveau, cet agencement n'est pas optimal au niveau de la transmission sonore.The document EP2942675 describes a watch in which the heel bearing the stamp cooperates with a membrane, lateral openings being provided in the bottom of the piece. Again, this arrangement is not optimal at the sound transmission.

Finalement, le document EP3009895 décrit une montre à sonnerie comprenant une glace de fond qui est suspendue par l'intermédiaire d'une pièce de support et de connexion, de telle sorte que ladite glace peut vibrer axialement. Une cavité est formée entre ladite pièce de support et de connexion et la lunette de fond, cette dernière comprenant des ouvertures latérales qui débouchent dans cette cavité. Il va sans dire qu'une glace de fond vibrante est inférieure à une membrane au niveau de la transmission sonore à cause de son inertie relativement importante, ce qui limite son amplitude et sa fréquence de vibration.Finally, the document EP3009895 discloses a bell watch comprising a bottom window which is suspended via a support and connection piece, so that said window can vibrate axially. A cavity is formed between said support and connection piece and the bottom bezel, the latter comprising lateral openings which open into this cavity. It goes without saying that ice cream Vibrating bottom is less than a membrane at the level of sound transmission because of its relatively high inertia, which limits its amplitude and frequency of vibration.

Le but de l'invention est par conséquent de proposer une pièce d'horlogerie dans laquelle les défauts susmentionnés sont au moins partiellement surmontés.The object of the invention is therefore to provide a timepiece in which the aforementioned defects are at least partially overcome.

Divulguation de l'inventionDisclosure of the invention

De façon plus précise, et selon un premier aspect, l'invention concerne une pièce d'horlogerie comprenant une boite de montre comportant une carrure et un fond monté sur ladite carrure, ainsi qu'un mouvement logé dans ladite boite de montre. Le mouvement comprend un bâti comme généralement connu.More specifically, and according to a first aspect, the invention relates to a timepiece comprising a watch case having a middle and a bottom mounted on said middle, and a movement housed in said watch case. The movement includes a frame as generally known.

La pièce d'horlogerie comprend également un mécanisme de sonnerie comprenant au moins un timbre logé dans ladite carrure, le mécanisme de sonnerie étant intégré au mouvement ou formant un module distinct du mouvement. Le timbre peut par exemple être porté par le bâti, par la carrure, ou par un autre élément solidaire de l'un ou l'autre de ces éléments.The timepiece also comprises a striking mechanism comprising at least one stamp housed in said middle part, the striking mechanism being integrated in the movement or forming a module distinct from the movement. The stamp may for example be carried by the frame, by the middle part, or by another element integral with one or the other of these elements.

Afin d'assurer l'étanchéité de la carrure côté fond ainsi que la transmission sonore entre l'intérieur et l'extérieur de la pièce d'horlogerie, une membrane est prévue entre ledit mécanisme de sonnerie et ledit fond.In order to ensure the sealing of the middle side and the sound transmission between the inside and outside of the timepiece, a membrane is provided between said striking mechanism and said bottom.

Selon cet aspect de l'invention, ladite membrane coopère directement ou indirectement avec un élément dudit bâti (tel qu'un pont, une platine ou un autre élément similaire) par l'intermédiaire d'un élément de transmission coopérant à la fois avec chacun de ces deux éléments. Cet élément de transmission peut être venu de matière dudit élément du bâti ou de ladite membrane, ou peut comporter une ou plusieurs pièces distinctes, sa coopération avec la membrane se trouvant à un point éloigné de la périphérie de cette dernière. De préférence, ledit point est éloigné de la périphérie de la membrane à raison d'au moins un sixième de sa largeur (c'est-à-dire d'au moins un tiers de son rayon pour une membrane circulaire, la largeur d'un cercle étant bien entendu son diamètre), de préférence d'au moins un quart de sa largeur. Encore de préférence, ce contact se trouve substantiellement au centre de ladite membrane, c'est-à-dire écarté dudit centre à raison d'au maximum 5% (ou même 2,5%) de ladite largeur.According to this aspect of the invention, said membrane cooperates directly or indirectly with an element of said frame (such as a bridge, a plate or other similar element) via a transmission element cooperating with both each of these two elements. This transmission element may be made of material from said frame member or said membrane, or may comprise one or more separate parts, its cooperation with the membrane being at a point remote from the periphery of the latter. Preferably, said point is remote from the periphery of the membrane by at least one-sixth of its width (i.e., at least one-third of its radius for a circular membrane, the width of a circle being of course its diameter), preferably from less than a quarter of its width. More preferably, this contact is substantially in the center of said membrane, that is to say spaced from said center at a maximum of 5% (or even 2.5%) of said width.

Le contact direct ou indirect entre, par exemple, une platine ou un pont et la membrane assure une excellente transmission de son vers la membrane (et donc vers l'extérieur) lors de l'actionnement du timbre par le biais d'un marteau ou d'autres moyens ad hoc. Non seulement l'intensité, mais aussi la qualité sonore perçue par l'utilisateur, sont augmentées, sans atténuation due à un contact entre par exemple le fond et le poignet de l'utilisateur.The direct or indirect contact between, for example, a plate or a bridge and the membrane ensures excellent transmission of sound to the membrane (and therefore to the outside) when actuating the stamp by means of a hammer or other ad hoc means. Not only the intensity, but also the sound quality perceived by the user, are increased, without attenuation due to contact between for example the bottom and the wrist of the user.

Avantageusement, ledit élément de transmission est un plot qui est solidaire d'un élément de bâti ou de la membrane.Advantageously, said transmission element is a stud which is integral with a frame element or the membrane.

Avantageusement, ledit élément dudit bâti est un pont de transmission de son, qui peut être solidaire des autres éléments du bâti et peut par exemple servir pour transmettre des vibrations du bâti autour d'autres composants du mouvement.Advantageously, said element of said frame is a sound transmission bridge, which may be integral with the other elements of the frame and may for example be used to transmit vibrations of the frame around other components of the movement.

Avantageusement, ledit pont de transmission de son définit, conjointement avec une platine que comporte ledit bâti, un volume logeant un mécanisme horloger tel qu'un système de remontage automatique, ledit mécanisme de sonnerie ou tout autre mécanisme horloger.Advantageously, said sound transmission bridge defines, together with a plate that includes said frame, a volume housing a clock mechanism such as an automatic winding system, said striking mechanism or any other clock mechanism.

Avantageusement, ledit plot est directement solidaire d'une platine que comporte ledit bâti, ou de la membrane.Advantageously, said pad is directly integral with a plate that includes said frame, or the membrane.

Avantageusement, une gouttière est prévue à l'intérieur de la carrure, notamment s'étendant au moins en partie à la périphérie intérieure de la carrure, cette gouttière étant ouverte en direction du fond. Elle peut, en outre, se trouver au moins partiellement autour ou au-dessus dudit mouvement. Cette gouttière agit comme caisse de résonance, ce qui améliore d'autant plus les propriétés sonores de l'agencement.Advantageously, a gutter is provided inside the middle part, in particular extending at least in part to the inner periphery of the middle part, this gutter being open towards the bottom. It can, moreover, be at least partially around or above said movement. This gutter acts as a sound box, which improves all the more the sound properties of the arrangement.

Avantageusement, ladite gouttière est interposée entre ledit pont de transmission de son et un autre élément dudit bâti auquel elle est solidarisée, comme par exemple une platine. Ce faisant, la gouttière est exposée à un maximum de vibrations transmises par le timbre qui peut être solidaire de la gouttière et en contact permanent uniquement avec cette dernière.Advantageously, said channel is interposed between said sound transmission bridge and another element of said frame to which it is secured, such as a plate. In doing so, the gutter is exposed to a maximum of vibrations transmitted by the stamp which can be integral with the gutter and in permanent contact only with the latter.

Avantageusement ladite membrane est précontrainte par ledit élément de transmission, ce qui maximise la transmission de son entre l'élément de transmission et la membrane.Advantageously, said membrane is prestressed by said transmission element, which maximizes the transmission of sound between the transmission element and the membrane.

Selon un deuxième aspect, l'invention concerne une pièce d'horlogerie comprenant une boite de montre qui comprend une carrure et un fond solidaire de ladite carrure, un mouvement logé dans ladite boite de montre comprenant un bâti, un mécanisme de sonnerie comprenant au moins un timbre logé dans ladite carrure ainsi qu'une membrane agencée pour la transmission du son.According to a second aspect, the invention relates to a timepiece comprising a watch case which comprises a middle part and a base integral with said middle part, a movement housed in said watch case comprising a frame, a striking mechanism comprising at least a stamp housed in said middle and a membrane arranged for the transmission of sound.

Selon cet aspect de l'invention, la carrure est percée latéralement d'une ouverture traversante, ladite membrane est agencée dans ou sur une paroi latérale de ladite carrure, et ledit timbre est fixé à ladite membrane.According to this aspect of the invention, the middle part is pierced laterally with a through opening, said membrane is arranged in or on a side wall of said middle part, and said stamp is fixed to said membrane.

Par ces moyens, un maximum de vibrations sont transmises directement à la membrane, qui est libre d'osciller sans empêchement. L'intensité et la qualité sonores sont ainsi améliorées. Le fait que la membrane soit agencée sur la paroi latérale de la carrure au lieu de l'être sur sa face inférieure empêche le poignet du porteur d'étouffer le son.By these means, a maximum of vibrations are transmitted directly to the membrane, which is free to oscillate without impediment. The intensity and the sound quality are thus improved. The fact that the membrane is arranged on the side wall of the middle part instead of being on its lower face prevents the wearer's wrist from muffling the sound.

Avantageusement, ladite membrane est fixée à ladite carrure par l'intermédiaire d'une bride.Advantageously, said membrane is attached to said middle through a flange.

Avantageusement, ledit timbre est porté par un porte-timbre qui est fixé à ladite membrane.Advantageously, said stamp is carried by a stamp holder which is fixed to said membrane.

Finalement, on note que les propriétés sonores d'une membrane en verre métallique, c'est-à-dire en alliage de métal substantiellement amorphe, sont très bonnes, et donc ce matériau peut être utilisé pour la membrane dans chacun des aspects de l'invention. Alternativement, d'autres matériaux sont possibles, tels que du laiton, de l'acier, du nickel, ou similaire.Finally, it is noted that the sound properties of a metal glass membrane, that is to say a substantially amorphous metal alloy, are very good, and therefore this material can be used for the membrane in each of the aspects of the membrane. 'invention. Alternatively, other materials are possible, such as brass, steel, nickel, or the like.

Modes de réalisation de l'inventionEmbodiments of the invention

La figure 1 illustre une pièce d'horlogerie 1 selon le premier aspect de l'invention.The figure 1 illustrates a timepiece 1 according to the first aspect of the invention.

Cette pièce d'horlogerie 1 comporte une boite de montre composée d'une carrure 3, d'une glace 5 portée par une lunette 7 ainsi qu'un fond 9. Ce dernier est muni d'une pluralité d'ouvertures 13 discrètes distribuées autour du pourtour du fond 9, ces dernières constituant des conduits sonores pour le passage de sons émanant de l'intérieur de la boite comme généralement connu.This timepiece 1 comprises a watch case composed of a middle part 3, an ice cream 5 carried by a bezel 7 and a bottom 9. The latter is provided with a plurality of discrete openings 13 distributed around around the bottom 9, the latter constituting sound conduits for the passage of sounds emanating from the inside of the box as generally known.

Côté cadran, l'étanchéité de la boite est assurée de manière classique avec des joints d'étanchéité 11; coté fond, puisque ce dernier est muni d'ouvertures 13, l'étanchéité est assurée par une membrane 15 qui est fixée sur la face inférieure de la carrure 3 par des moyens ad hoc, et qui est agencée pour favoriser la transmission sonore. Dans le mode de réalisation illustré, la membrane 15 est tenue en sandwich entre le fond 9 et un pré-fond 10 qui est fixé sur la carrure 3 par l'intermédiaire de vis 14 ou par coopération entre un filetage et un taraudage que comportent le pré-fond 10 et la carrure 3, de manière classique. Alternativement, le fond 9 peut être monté directement sur la carrure 3. L'étanchéité entre la membrane 15 et le pré-fond 10 est assurée par un autre joint d'étanchéité 11 périphérique, tenu également en sandwich entre ces deux éléments, et le pré-fond 10 est rendu étanche à la carrure 3 par un moyen ad hoc tel qu'un joint d'étanchéité classique 12.Side dial, the sealing of the box is provided in a conventional manner with seals 11; side bottom, since the latter is provided with openings 13, the seal is provided by a membrane 15 which is fixed on the underside of the middle part 3 by ad hoc means, and which is arranged to promote the sound transmission. In the illustrated embodiment, the membrane 15 is sandwiched between the bottom 9 and a pre-bottom 10 which is fixed to the middle part 3 by means of screws 14 or by cooperation between a thread and a tapping that comprise the pre-background 10 and the middle part 3, in a conventional manner. Alternatively, the bottom 9 can be mounted directly on the middle part 3. The seal between the membrane 15 and the pre-base 10 is provided by another peripheral seal 11, also sandwiched between these two elements, and the pre-bottom 10 is rendered waterproof to the middle 3 by an ad hoc means such as a conventional seal 12.

La membrane 15 peut présenter une section d'épaisseur uniforme, ou peut présenter des parties plus épaisses ou plus minces 15a servant à modifier les propriétés élastiques de la membrane 15 afin d'optimiser la transmission sonore. La membrane 15 peut avantageusement être fabriquée en verre métallique, qui présente des propriétés mécaniques et sonores intéressantes, mais d'autres matériaux tels que du métal conventionnel (comme le laiton ou l'acier), du polymère (comme l'Aramide ou le Gore-Tex) ou similaire sont également utilisables. Considérée dans son plan, la membrane 15 peut être par exemple circulaire, ovale, carrée, rectangulaire, ou similaire.The membrane 15 may have a section of uniform thickness, or may have thicker or thinner portions 15a for modifying the elastic properties of the membrane 15 to optimize sound transmission. The membrane 15 may advantageously be made of metal glass, which has interesting mechanical and sonic properties, but other materials such as conventional metal (such as brass or steel), polymer (such as Aramid or Gore -Tex) or similar are also usable. Regarded in its plane, the membrane 15 may be for example circular, oval, square, rectangular, or the like.

À l'intérieur de la boite est logé, de manière classique, un mouvement horloger 17 comprenant un mécanisme de sonnerie quelconque, qui peut être un mécanisme à répétition, un mécanisme de réveil ou tout autre mécanisme similaire. L'ensemble des composants mobiles que comporte le mouvement est soutenu par un bâti comportant une platine 19 ainsi que des ponts 21 de façon connue. Il est également possible que le mécanisme de sonnerie ne soit pas intégré au mouvement, en étant prévu en tant que module distinct logé dans la carrure 3.Inside the box is housed, in a conventional manner, a watch movement 17 comprising any striking mechanism, which may be a repetitive mechanism, an alarm mechanism or any other similar mechanism. The set of moving components that comprises the movement is supported by a frame comprising a plate 19 and bridges 21 in a known manner. It is also possible that the striking mechanism is not integrated in the movement, being provided as a separate module housed in the caseband 3.

Le mécanisme de sonnerie comporte un timbre 23 en forme de fil qui s'étend le long d'une cavité autour d'au moins une partie du mouvement 17 et est destiné à être frappé par un marteau (non illustré). Le timbre 23 est monté sur une gouttière 31 (voir ci-dessous) par l'intermédiaire d'un porte-timbre (non illustré) qui est fixé à cette gouttière 31, par exemple par l'intermédiaire de vis. Le porte-timbre peut être une pièce rapportée sur la gouttière, ou peut être venu de matière avec cette dernière. Alternativement, le porte-timbre peut être fixé directement au bâti ou à la carrure 3, ou indirectement par l'intermédiaire d'une pièce quelconque. Par ailleurs, le timbre 23 peut encore alternativement être en forme de cloche agencée d'une manière appropriée. Dans le cas d'un timbre en fil, ce dernier peut présenter n'importe quelle forme de section, par exemple circulaire, ovale, carrée, rectangulaire, en forme de « U », ou similaire. Sa section peut être constante ou peut varier le long du timbre.The striking mechanism comprises a wire-shaped patch 23 which extends along a cavity around at least a portion of the movement 17 and is intended to be struck by a hammer (not shown). The stamp 23 is mounted on a gutter 31 (see below) via a stamp holder (not shown) which is fixed to this channel 31, for example by means of screws. The stamp holder may be a patch on the gutter, or may be integral with the gutter. Alternatively, the stamp holder can be fixed directly to the frame or the middle part 3, or indirectly via any part. Moreover, the stamp 23 may alternatively be bell-shaped arranged in a suitable manner. In the case of a wire stamp, the latter may have any shape of section, for example circular, oval, square, rectangular, in "U" shape, or the like. Its section may be constant or may vary along the timbre.

Le bâti comporte en outre un pont de transmission de son 25, qui est monté sur la platine 19 par l'intermédiaire d'une pluralité de vis 27. Le pont 25 peut présenter une forme de lame pliée, ou alternativement peut être en forme de coupole ou de bol, plein ou ajouré. Le pont 25 est en contact avec le centre de la membrane 15, par l'intermédiaire d'un élément de transmission 29 sous forme de plot qui est venu de matière avec le pont 25 et qui applique une précontrainte à la membrane 15. Cette précontrainte étant indiquée schématiquement par l'intermédiaire du chevauchement entre ces deux éléments, qui est dû aux limitations du logiciel de dessin ne permettant pas de modéliser la forme résultante de la membrane 15. Alternativement, le plot 29 peut être venu de matière avec la membrane 15, ou peut être un élément rapporté soit sur la membrane 15, soit sur le pont 25. En tout cas, le plot 29 coopère à la fois avec la membrane 15 et le pont 25.The frame further comprises a sound transmission bridge 25, which is mounted on the plate 19 by means of a plurality of screws 27. The bridge 25 may have a folded blade shape, or alternatively may be in the form of cupola or bowl, full or openwork. The bridge 25 is in contact with the center of the membrane 15, via a transmission element 29 in the form of a pad which is integral with the bridge 25 and which applies a prestress to the membrane 15. This prestressing being indicated diagrammatically by means of the overlap between these two elements, which is due to the limitations of the drawing software not making it possible to model the resultant shape of the membrane 15. Alternatively, the stud 29 may be integral with the membrane 15 , or may be an element attached to either the membrane 15 or the bridge 25. In any case, the stud 29 cooperates with both the membrane 15 and the bridge 25.

Puisque le timbre 23 est monté solidaire du bâti, directement ou par l'intermédiaire d'une gouttière 31 (si présente), lorsqu'il vibre suite à l'impact d'un marteau, le pont de transmission de son 25 vibre également, et transmet cette vibration à la membrane. Le pont 25 contribue au déplacement d'un volume d'air plus grand de ce qui est typiquement le cas, ce qui augmente l'intensité ainsi que la qualité sonore. Par ailleurs, puisque la vibration est transmise à la membrane 15 par un contact intime par le biais du plot 29, l'amplitude de vibration de cette dernière est augmentée, ce qui contribue également à une transmission sonore augmentée. On note par ailleurs que le plot 29 peut être décentré par rapport à la membrane 15, et que plusieurs plots 29 peuvent être prévus. Le contact entre le plot 29 et la membrane 15 est ainsi éloigné de la périphérie de cette dernière, et n'est donc pas à sa périphérie. Plus précisément, la distance entre le pourtour de la membrane et ce point de contact est de préférence au moins un sixième de la largeur (c'est-à-dire du diamètre dans le cas d'une membrane circulaire) de cette dernière, encore de préférence au moins un quart de sa largeur / de son diamètre.Since the patch 23 is mounted integral with the frame, directly or via a gutter 31 (if present), when it vibrates following the impact of a hammer, the sound transmission bridge also vibrates, and transmits this vibration to the membrane. The bridge 25 contributes to the displacement of a larger volume of air than is typically the case, which increases the intensity as well as the sound quality. Moreover, since the vibration is transmitted to the membrane 15 by intimate contact through the stud 29, the vibration amplitude of the latter is increased, which also contributes to an increased sound transmission. Note also that the pad 29 may be off-center with respect to the membrane 15, and that several pads 29 may be provided. The contact between the stud 29 and the membrane 15 is thus remote from the periphery of the latter, and is therefore not at its periphery. More specifically, the distance between the periphery of the membrane and this point of contact is preferably at least one sixth of the width (that is to say the diameter in the case of a circular membrane) of the latter, again preferably at least a quarter of its width / diameter.

Le pont de transmission de son 25 peut être directement monté sur la platine 19 ou sur un pont 21, mais une gouttière 31 peut avantageusement être interposée entre le rebord du pont de transmission de son 25 et le bâti.The sound transmission bridge 25 may be directly mounted on the plate 19 or on a bridge 21, but a channel 31 may advantageously be interposed between the rim of the sound transmission bridge 25 and the frame.

Cette gouttière 31 s'étend au moins partiellement autour du pourtour intérieur de la carrure 3 et est donc au moins partiellement annulaire, et présente un profil en « U », dont le fond est tenu en sandwich entre le rebord du pont 25 et la platine, les parois s'étendant de part et d'autre de la partie adjacente du pont 25. La gouttière 31 sert comme caisse de résonance, dont les dimensions peuvent être adaptées aux propriétés sonores (notamment au niveau de sa fréquence de résonance) du timbre 23. Bien entendu, la gouttière 31 peut s'étendre à l'intérieur du pourtour de la carrure 3 et ainsi former un anneau fermé.This channel 31 extends at least partially around the inner periphery of the middle part 3 and is therefore at least partially annular, and has a "U" profile, the bottom of which is sandwiched between the edge of the bridge 25 and the plate , the walls extending on either side of the adjacent portion of the bridge 25. The gutter 31 serves as a sound box, whose dimensions can be adapted to the sound properties (especially at its resonance frequency) of the stamp 23. Of course, the channel 31 may extend inside the perimeter of the middle part 3 and thus form a closed ring.

On note par ailleurs que le fond de la gouttière 31 est séparé de la platine 19 par des rondelles 33 qui entourent chacune une vis 27 correspondante. Les rondelles 33 peuvent être des pièces distinctes, ou peuvent être venues de matière soit avec la platine, soit avec la gouttière. Ce faisant, la gouttière et le pont de transmission 25 peuvent vibrer plus librement, et de l'air peut pénétrer dans l'espace constitué entre la platine 19 et la gouttière 31, ce qui améliore également les propriétés sonores de l'ensemble. On note que l'utilisation de trois points de fixation entre la gouttière 31 et la platine 19 a donnée d'excellents résultats. Pour le surplus, on note en outre qu'il n'est pas obligatoire de fixer le pont 25 à la gouttière 31 par l'intermédiaire de vis ou similaire ; la précontrainte de la membrane 15 peut suffire pour maintenir le pont 25 en place, le cas échéant.Note also that the bottom of the channel 31 is separated from the plate 19 by washers 33 which each surround a screw 27 corresponding. The washers 33 may be separate pieces, or may be of material either with the plate or with the gutter. In doing so, the gutter and the transmission bridge 25 can vibrate more freely, and air can enter the space formed between the plate 19 and the channel 31, which also improves the sound properties of the assembly. It is noted that the use of three fixing points between the trough 31 and the plate 19 gave excellent results. For the rest, it is further noted that it is not mandatory to fix the bridge 25 to the gutter 31 by means of screws or the like; prestressing the membrane 15 may be sufficient to hold the bridge 25 in place, if necessary.

Cependant, la gouttière 31 et/ou les rondelles 33 peuvent être facultatives. En l'absence de la gouttière 31, la caisse de résonance est formée par la carrure 3, le mouvement 17 ainsi que le pont de transmission de son 25.However, the gutter 31 and / or the washers 33 may be optional. In the absence of the gutter 31, the sound box is formed by the middle part 3, the movement 17 as well as the sound transmission bridge 25.

On note par ailleurs que cette construction est compatible avec un mouvement 17 à remontage automatique, un système de masse oscillante 35 étant disposé entre le pont de transmission de son 25 et la platine 19. Ce système de masse oscillante 35 peut être de n'importe quel genre, et n'est illustré que schématiquement en lien avec l'espace qu'il occupe. Le pont 25 permet donc de transmettre des vibrations venant d'autres éléments du bâti autour de ce mécanisme 35 vers la membrane 15.It should also be noted that this construction is compatible with a self-winding movement 17, an oscillating weight system 35 being disposed between the sound transmission bridge 25 and the plate 19. This oscillating mass system 35 can be of any size. what kind, and is illustrated only schematically in relation to the space it occupies. The bridge 25 Thus, it is possible to transmit vibrations coming from other elements of the frame around this mechanism 35 towards the membrane 15.

La figure 2 illustre un deuxième mode de réalisation d'une pièce d'horlogerie 1 selon le premier aspect de l'invention. Sur cette figure, seuls les signes de référence mentionnés explicitement ont été reproduits sur la figure, les autres éléments restant substantiellement inchangés par rapport à la figure 1.The figure 2 illustrates a second embodiment of a timepiece 1 according to the first aspect of the invention. In this figure, only the reference signs mentioned explicitly have been reproduced in the figure, the other elements remaining substantially unchanged from the figure 1 .

Dans cette variante, le pont de transmission 25 est de taille relativement réduite et comprend un plateau 25a qui prend place contre la platine 19 et est fixé sur cette dernière ainsi qu'un plot 25b s'étendant depuis le plateau 25a en direction de la membrane 15. Le plateau 25a comporte également une partie creuse 25c servant à conférer de la place pour une partie de la minuterie 37.In this variant, the transmission bridge 25 is relatively small in size and comprises a plate 25a which seats against the plate 19 and is fixed on the latter and a pad 25b extending from the plate 25a towards the membrane The tray 25a also has a hollow portion 25c for providing space for a portion of the timer 37.

Ce plot 25b coopère avec la membrane 15 par l'intermédiaire d'un élément de liaison 39 qui, ensemble avec le plot 25b, font office d'élément de transmission. Dans la variante illustrée, ce dernier est sous forme de tube posé sur ledit plot 25b, mais peut également présenter une forme pleine. Par ailleurs, il est également possible que le plot 25b soit plus long et entre en contact direct avec la membrane 15 et/ou que le plateau 25a soit supprimé. Le plot 25b peut être centré ou décentré par rapport au mouvement 17 et/ou à la membrane 15, comme également mentionné ci-dessus dans le cadre de la figure 1. Dans encore une autre variante, l'élément de liaison 39 peut être en contact direct avec la platine 19 ou un pont quelconque, et peut également éventuellement être venu de matière avec la membrane 15. Par exemple, l'élément de liaison 39 peut être un pilier solidaire de, ou venu de matière avec, la membrane 15 ou un élément quelconque du bâti.This stud 25b cooperates with the membrane 15 via a connecting element 39 which, together with the stud 25b, act as a transmission element. In the illustrated variant, the latter is in the form of a tube placed on said stud 25b, but may also have a solid shape. Furthermore, it is also possible that the pad 25b is longer and comes into direct contact with the membrane 15 and / or that the plate 25a is removed. The pad 25b may be centered or off-center with respect to the movement 17 and / or the membrane 15, as also mentioned above in connection with the figure 1 . In yet another variant, the connecting element 39 may be in direct contact with the plate 19 or any bridge, and may also possibly be integral with the membrane 15. For example, the connecting element 39 may be a pillar integral with or integral with the membrane 15 or any element of the frame.

Cette construction est particulièrement avantageuse lorsqu'aucun système de remontage automatique 35 n'est présent, ou si, comme dans la pièce illustrée sur la figure 2, ce dernier présente une ouverture centrale au travers de laquelle le plot 25b peut traverser.This construction is particularly advantageous when no automatic winding system 35 is present, or if, as in the part illustrated on the figure 2 , the latter has a central opening through which the stud 25b can pass.

Les figures 3a à 3c illustrent une partie d'un mode de réalisation d'une pièce d'horlogerie 1 selon le deuxième aspect de l'invention. Dans ce mode de réalisation, la membrane 15 se situe sur la paroi latérale extérieure d'une carrure 3 qui fait partie de la boîte de montre de la pièce d'horlogerie 1. Les autres éléments de la pièce d'horlogerie se trouvant à l'intérieur de la boite de montre (mouvement, mécanisme de sonnerie etc.) ainsi que les autres éléments de l'habillage (fond, lunette, glace) n'ont pas été représentés sur ces figures, et peuvent être identiques à ceux des figures 1 et 2. Il va sans dire que la paroi latérale extérieure de la carrure est celle qui ne porte ni le verre, ni le fond et qui s'étend perpendiculairement au plan du mouvement et donc à celle de la pièce d'horlogerie.The Figures 3a to 3c illustrate a part of an embodiment of a timepiece 1 according to the second aspect of the invention. In this embodiment, the membrane 15 is located on the outer side wall of a middle part 3 which is part of the watch case of the timepiece 1. The other elements of the timepiece located in the the inside of the watch case (movement, striking mechanism, etc.) as well as the other elements of the covering (bottom, bezel, ice) have not been represented in these figures, and may be identical to those of the figures 1 and 2 . It goes without saying that the outer side wall of the middle part is one that carries neither the glass nor the bottom and extends perpendicularly to the plane of movement and therefore to that of the timepiece.

La membrane 15 couvre et rend étanche une ouverture 3a pratiquée dans ladite paroi latérale, l'ouverture s'étendant au travers de l'ensemble de l'épaisseur de la carrure. Elle est fixée à la carrure 3 par une bride 43 qui comporte une ouverture 43a ; la membrane 15 est alors prise en sandwich entre la bride 43 et la carrure 3, et sa partie centrale peut vibrer librement. La bride 43 est rendue solidaire de la carrure par l'intermédiaire d'une paire de vis 45 ou d'autres moyens appropriés, mais elle peut alternativement être soudée, brasée, collée ou similaire, et/ou la membrane 15 peut être également soudée, brasée, collée ou similaire en place. Dans ce dernier cas, la bride 43 est facultative. Il est également possible de prévoir un joint d'étanchéité entre la membrane 15 et la carrure 3 en cas de besoin, et il est également possible que la membrane 15 fasse office de joint d'étanchéité.The membrane 15 covers and seals an opening 3a formed in said side wall, the opening extending through the entire thickness of the middle part. It is fixed to the middle part 3 by a flange 43 which has an opening 43a; the membrane 15 is then sandwiched between the flange 43 and the middle part 3, and its central part can vibrate freely. The flange 43 is secured to the middle part by means of a pair of screws 45 or other suitable means, but may alternatively be welded, brazed, glued or the like, and / or the membrane 15 may also be welded brazed, glued or the like in place. In the latter case, the flange 43 is optional. It is also possible to provide a seal between the membrane 15 and the middle part 3 if necessary, and it is also possible that the membrane 15 act as a seal.

Dans ce mode de réalisation, le timbre 23 est en forme de fil présentant une section quelconque (comme mentionné ci-dessus), et est porté par un porte-timbre 41 qui est fixé directement ou indirectement à la membrane 15. Dans la variante illustrée, une vis 47 est utilisée pour attacher le porte-timbre 41 au centre de la membrane 15, une entretoise 49 tubulaire servant à déterminer la séparation entre le porte-timbre 41 et la membrane 15. Alternativement, le porte-timbre 41 peut s'étendre en direction de la membrane 15 afin de coopérer directement avec ce dernier. Un joint d'étanchéité ad hoc peut être prévu entre la membrane 15 et la vis 47 afin de rendre cet ensemble étanche, en cas de besoin. Par ailleurs, une gouttière présentant un profil en « U » peut être fixée entre le porte-timbre 41 et la membrane 15, le fond du profil en « U » de la gouttière étant en contact direct ou indirect avec la membrane 15. Dans un tel cas, la gouttière est ouverte vers l'intérieur ou l'extérieur de la carrure 3, et sert à faire vibrer un volume d'air plus important.In this embodiment, the patch 23 is in the form of a wire having any cross-section (as mentioned above), and is carried by a stamp holder 41 which is fixed directly or indirectly to the membrane 15. In the illustrated variant a screw 47 is used to attach the stamp holder 41 to the center of the diaphragm 15, a tubular spacer 49 for determining the separation between the stamp holder 41 and the diaphragm 15. Alternatively, the stamp holder 41 may be extend towards the membrane 15 to cooperate directly with the latter. An appropriate seal may be provided between the membrane 15 and the screw 47 to make this assembly waterproof, if necessary. Furthermore, a channel having a "U" profile can be fixed between the stamp holder 41 and the membrane 15, the bottom of the "U" profile of the channel being in direct or indirect contact with the membrane 15. In a such case, the gutter is open towards the inside or outside of the middle part 3, and serves to vibrate a larger volume of air.

Par ces moyens, les vibrations du timbre 23 suite à une frappe reçue de la part d'un marteau (non illustré) sont transmises directement et mécaniquement à la membrane 15, qui se situe à un endroit sur la paroi extérieure de la carrure qui est dégagé de tout contact du poignet du porteur. L'intensité de la transmission sonore est ainsi améliorée.By these means, the vibrations of the stamp 23 following a strike received from a hammer (not shown) are transmitted directly and mechanically to the membrane 15, which is located at a location on the outer wall of the middle part which is free from contact with the wrist of the wearer. The intensity of the sound transmission is thus improved.

Les figures 4a et 4b illustrent une variante du mode de réalisation des figures 3a à 3c, qui diffère de ce dernier en ce que la membrane 15 n'est pas posée directement sur la surface de la paroi extérieure de la carrure 3, mais est encastrée par rapport à cette dernière.The Figures 4a and 4b illustrate a variant of the embodiment of Figures 3a to 3c , which differs from the latter in that the membrane 15 is not placed directly on the surface of the outer wall of the middle part 3, but is recessed relative thereto.

À cet effet, la carrure 3 comporte un rebord renfoncé 3b qui entoure l'ouverture 3a et qui définit un épaulement sur lequel la membrane 15 est posée. Dans la variante illustrée, la forme du rebord 3b et de la bride 43 a été choisie de telle sorte qu'au moins une partie de l'épaisseur de la bride 43 est rabattue par rapport à la surface de la paroi latérale de la carrure 3. Il est également possible que la bride 43 puisse être entièrement rabattue par rapport à la surface de la carrure 43, ou que sa surface puisse se trouver dans le prolongement de cette dernière. Il est également possible que la profondeur du rebord 3b corresponde à l'épaisseur de la membrane 15, de telle sorte que la membrane 15 se trouve dans le prolongement de la surface de la carrure 3. Cette dernière option est notamment intéressante dans le cas où la membrane 15 est soudée sur la carrure 3, ou si la membrane 15 est venue de matière avec la carrure 3.For this purpose, the middle part 3 comprises a recessed flange 3b which surrounds the opening 3a and which defines a shoulder on which the membrane 15 is placed. In the variant shown, the shape of the flange 3b and the flange 43 has been chosen so that at least a portion of the thickness of the flange 43 is folded relative to the surface of the side wall of the middle part 3 It is also possible for the flange 43 to be fully folded with respect to the surface of the middle part 43, or that its surface may be in line with the latter. It is also possible that the depth of the rim 3b corresponds to the thickness of the membrane 15, so that the membrane 15 is in the extension of the surface of the middle part 3. This last option is particularly interesting in the case where the membrane 15 is welded to the caseband 3, or if the membrane 15 is integral with the caseband 3.

Bien que l'invention ait été décrite ci-dessus en lien avec des modes de réalisation spécifiques, des variantes supplémentaires sont également envisageables sans sortir de la portée de l'invention comme définie par les revendications.Although the invention has been described above in connection with specific embodiments, additional variants are also can be envisaged without departing from the scope of the invention as defined by the claims.
