Description

Domaine techniqueTechnical area

L'invention concerne un mécanisme musical ou de sonnerie pour pièce d'horlogerie ou boîte à musique comprenant une source d'énergie délivrant un couple mécanique et des moyens de transmission de couple mécanique depuis ladite source d'énergie vers un mobile de génération de musique ou de sonnerie. L'invention concerne également une pièce d'horlogerie ou boîte à musique comprenant un tel mécanisme musical ou de sonnerie, ainsi qu'une utilisation d'un régulateur de mobile musical ou de sonnerie particulier dans un tel mécanisme. De façon plus particulière elle concerne le domaine de l'horlogerie, et plus particulièrement celui des pièces d'horlogerie comportant un mécanisme de sonnerie ou un mécanisme musical, telles que montres mécaniques à sonnerie, boîtes à musiques ou similaires.The invention relates to a musical or striking mechanism for a timepiece or music box comprising an energy source delivering a mechanical torque and means for transmitting a mechanical torque from said energy source to a mobile for generating music. or ringtone. The invention also relates to a timepiece or music box comprising such a musical or ringing mechanism, as well as a use of a particular musical mobile or ringing regulator in such a mechanism. More particularly, it relates to the field of watchmaking, and more particularly that of timepieces comprising a striking mechanism or a musical mechanism, such as mechanical striking watches, music boxes or the like.

Arrière-plan technologiqueTechnological background

Les montres mécaniques à sonnerie disposent généralement d'un régulateur de sonnerie dont le rôle est de neutraliser l'effet des fortes variations de couple lors de l'armage des dispositifs de création du son afin de réguler le tempo de la sonnerie. En effet, dans les montres à répétition ou dans celles qui sonnent au passage de l'heure, les marteaux de sonnerie doivent être armés avant la frappe sur les timbres, qui doit être la plus forte possible pour maximiser le niveau acoustique. Le couple d'armage est optimisé en fonction de ce que le barillet de sonnerie peut fournir. Or, un tel barillet de sonnerie ne peut pas fournir de couple constant. La variation du tempo de la frappe étant étroitement liée à la courbe de désarmage du ressort de barillet, dans bien des cas, la sonnerie ou la musique ralentit à la fin de la fonction, ce qui est désagréable pour l'utilisateur. C'est pourquoi un régulateur de sonnerie est utilisé en parallèle de l'armage des marteaux, qui permet de stabiliser la vitesse de désarmage du barillet et d'ainsi obtenir une frappe d'amplitude et de tempo constants. Un tel régulateur est souvent constitué d'une inertie en rotation dont la dissipation de l'énergie est généralement faite soit par variation d'inertie, soit par friction, soit par des courants de Foucault, soit par une combinaison de différentes méthodes. Un tel régulateur de sonnerie est par exemple décrit dans la demande de brevet EP 2 487 547 A1 . Il existe également des systèmes à ancre pour effectuer une telle fonction de régulateur de sonnerie.Mechanical striking watches generally have a striking regulator, the role of which is to neutralize the effect of strong variations in torque during the arming of the sound creation devices in order to regulate the tempo of the striking. In fact, in repeater watches or in those which strike when the hour passes, the striking hammers must be cocked before striking the gongs, which must be as loud as possible to maximize the acoustic level. The winding torque is optimized depending on what the striking barrel can deliver. However, such a striking barrel cannot provide a constant torque. The variation in the tempo of the strike being closely related to the disarming curve of the barrel spring, in many cases the bell or the music slows down at the end of the stroke. function, which is unpleasant for the user. This is why a strike regulator is used in parallel with the winding of the hammers, which makes it possible to stabilize the speed of disarming of the barrel and thus to obtain a strike of constant amplitude and tempo. Such a regulator often consists of a rotating inertia, the energy of which is generally dissipated either by variation of inertia, or by friction, or by eddy currents, or by a combination of different methods. Such a ringing regulator is for example described in the patent application EP 2 487 547 A1 . There are also anchor systems to perform such a ring regulator function.

Le même principe est appliqué dans les montres musicales, où la frappe des timbres par des marteaux est remplacée par les lames d'un clavier qu'on arme à l'aide de goupilles en déplacement. Dans les boîtes à musique, ce régulateur prend souvent la forme d'ailettes tournant dans l'air à haute vitesse, pour minimiser les nuisances sonores.The same principle is applied in musical watches, where the striking of gongs by hammers is replaced by the blades of a keyboard which are armed with moving pins. In music boxes, this regulator often takes the form of fins rotating in the air at high speed, to minimize noise pollution.

Si de tels systèmes de régulation de mobiles de génération de musique ou de sonnerie remplissent relativement bien la fonction de régulation, l'intégralité de l'énergie dissipée dans le régulateur est cependant perdue. En outre, de tels systèmes de régulation sont assez bruyants en général.Although such systems for regulating music or ringing mobiles fulfill the regulation function relatively well, all of the energy dissipated in the regulator is however lost. In addition, such control systems are quite noisy in general.

Il existe donc un besoin de pouvoir disposer d'un mécanisme musical ou de sonnerie pour pièce d'horlogerie ou boîte à musique, permettant de récupérer tout ou partie de l'énergie dissipée dans le régulateur afin de disposer d'une source d'énergie rechargeable dans la pièce d'horlogerie ou dans la boîte à musique, tout en assurant une régulation optimale et discrète du mobile de génération de musique ou de sonnerie.There is therefore a need to be able to have a musical or ringing mechanism for a timepiece or music box, making it possible to recover all or part of the energy dissipated in the regulator in order to have an energy source. rechargeable in the timepiece or in the music box, while ensuring optimal and discreet regulation of the mobile generating music or ringing.

Résumé de l'inventionSummary of the invention

A cet effet, l'invention concerne un mécanisme musical ou de sonnerie pour pièce d'horlogerie ou boîte à musique, et qui comprend les caractéristiques mentionnées dans la revendication indépendante 1.To this end, the invention relates to a musical or striking mechanism for a timepiece or music box, and which comprises the characteristics mentioned in independent claim 1.

Des formes particulières du mécanisme musical ou de sonnerie sont définies dans les revendications dépendantes 2 à 10.Particular forms of the musical or ringing mechanism are defined in dependent claims 2 to 10.

Grâce à la présence d'un régulateur de mobile comprenant une génératrice électrique, dont un rotor est relié mécaniquement à la source d'énergie délivrant le couple mécanique, et un circuit électronique de régulation de la vitesse de rotation de la génératrice, l'énergie dissipée dans le régulateur est avantageusement récupérée sous forme d'énergie électrique. En effet, la tension alternative fournie par la génératrice électrique permet d'obtenir une source d'énergie électrique rechargeable au sein du mécanisme. L'énergie électrique fournie par une telle source d'énergie électrique peut ensuite, par exemple, permettre de charger un accumulateur électrique ou un condensateur, afin d'être avantageusement réutilisée par un composant électrique, tel qu'une diode électroluminescente pour illuminer des éléments de la pièce d'horlogerie, tels que des timbres, des marteaux ou des aiguilles par exemple. L'énergie électrique peut également, en variante, être réutilisée par un composant de génération de son ou de vibrations au sein du mécanisme. En outre, un tel régulateur fournit une régulation du couple mécanique délivré par la source d'énergie par freinage par la génératrice, qui est elle-même freinée électriquement par le circuit électronique, ce qui offre une régulation du mobile à la fois précise et silencieuse.Thanks to the presence of a mobile regulator comprising an electric generator, a rotor of which is mechanically connected to the energy source delivering the mechanical torque, and an electronic circuit for regulating the speed of rotation of the generator, the energy dissipated in the regulator is advantageously recovered in the form of electrical energy. In fact, the alternating voltage supplied by the electric generator makes it possible to obtain a source of rechargeable electric energy within the mechanism. The electrical energy supplied by such a source of electrical energy can then, for example, make it possible to charge an electrical accumulator or a capacitor, in order to be advantageously reused by an electrical component, such as a light-emitting diode to illuminate elements. of the timepiece, such as stamps, hammers or hands for example. The electrical energy can also, alternatively, be reused by a sound or vibration generating component within the mechanism.

Description détaillée de l'inventionDetailed description of the invention

L'invention concerne le domaine de l'horlogerie, et plus particulièrement celui des boîtes à musique ou des pièces d'horlogerie comportant un mécanisme musical ou de sonnerie. L'invention sera plus précisément décrite pour l'application préférée d'une pièce d'horlogerie comprenant un mécanisme de sonnerie. Néanmoins, l'invention est applicable à la régulation de tout mobile de génération de musique ou de sonnerie. A cet égard, on désignera dans la suite de l'exposé sous le terme générique « pièce d'horlogerie » une pièce d'horlogerie ou une boîte à musique, et sous le terme « mécanisme de sonnerie » un mécanisme musical ou de sonnerie.The invention relates to the field of watchmaking, and more particularly that of music boxes or timepieces comprising a musical or striking mechanism. The invention will be described more precisely for the preferred application of a timepiece comprising a striking mechanism. Nevertheless, the invention is applicable to the regulation of any mobile generating music or ringing. In this regard, in the remainder of the description, the generic term “timepiece” will denote a timepiece or a music box, and the term “striking mechanism” will denote a musical or striking mechanism.

Dans cette description d'une utilisation préférée de l'invention illustrée sur les figures 1 à 3, l'invention concerne un mécanisme de sonnerie 1 comprenant un régulateur 2 de mobile de sonnerie 4, pour une pièce d'horlogerie (non représentée sur les figures pour des raisons de clarté). La pièce d'horlogerie est typiquement une montre mécanique à sonnerie, telle que par exemple une montre à répétition. Dans cette utilisation préférée de l'invention illustrée sur les figures 1 à 3, le mobile de sonnerie 4 est un marteau de percussion qui est configuré pour venir frapper sur un timbre 5 du mécanisme de sonnerie 1. En variante non représentée, le mobile peut être un ou plusieurs levier(s), ou encore une ou plusieurs goupille(s) en déplacement qui viennent frapper sur les lames d'un clavier dans le cas d'une montre musicale. En variante encore, le timbre 5 peut être remplacé par un ou plusieurs résonateur(s), gong(s), ou cloche(s), ou encore par une caisse de résonance dans le cas d'une boîte à musique.In this description of a preferred use of the invention illustrated on figures 1 to 3 , the invention relates to a striking mechanism 1 comprising a regulator 2 for a striking mobile 4, for a timepiece (not shown in the figures for reasons of clarity). The timepiece is typically a mechanical striking watch, such as for example a repeater watch. In this preferred use of the invention illustrated on figures 1 to 3 , the ringing mobile 4 is a percussion hammer which is configured to strike a gong 5 of the striking mechanism 1. In a variant not shown, the mobile can be one or more lever (s), or one or more moving pin (s) which strike the blades of a keyboard in the case of a musical watch. As a further variant, the gong 5 can be replaced by one or more resonator (s), gong (s), or bell (s), or even by a resonance box in the case of a music box.

Comme visible sur la figure 3 le mécanisme de sonnerie 1 comprend, outre le régulateur 2, une source d'énergie 6 délivrant un couple mécanique, et des moyens de transmission de couple mécanique depuis la source d'énergie 6 vers le mobile de sonnerie 4 (ces derniers n'étant pas représentés sur les figures pour des raisons de clarté). De préférence, le mécanisme de sonnerie 1 comprend également au moins un composant électrique 10 relié au régulateur 2. Dans l'exemple de réalisation particulier illustré sur les figures 1 et 2, le mécanisme 1 comprend trois composants 10 de stockage d'énergie électrique, en l'occurrence des condensateurs céramique. L'énergie stockée dans ces condensateurs peut par exemple être réutilisée par des composants lumineux au sein de la pièce d'horlogerie afin d'effectuer une illumination synchronisée. En variante ou en complément, le(s) composant(s) électrique(s) 10 peu(ven)t être un accumulateur, et/ou un composant lumineux, tel qu'une diode électroluminescente, et/ou un composant électrique de génération de son ou de vibrations au sein du mécanisme 1. Lorsque le composant électrique 10 est un composant électrique de génération de son, ce dernier est par exemple un haut-parleur associé à un amplificateur.As visible on the figure 3 the striking mechanism 1 comprises, in addition to the regulator 2, an energy source 6 delivering a mechanical torque, and mechanical torque transmission means from the energy source 6 to the striking mobile 4 (the latter not being not shown in the figures for reasons of clarity). Preferably, the striking mechanism 1 also comprises at least one electrical component 10 connected to the regulator 2. In the particular embodiment illustrated in the FIGS. figures 1 and 2 , the mechanism 1 comprises three components 10 for storing electrical energy, in this case ceramic capacitors. The energy stored in these capacitors can for example be reused by light components within the timepiece in order to effect synchronized illumination. As a variant or in addition, the electrical component (s) 10 can be an accumulator, and / or a luminous component, such as a light-emitting diode, and / or an electrical generation component. of sound or vibrations within the mechanism 1. When the electrical component 10 is an electrical component for generating sound, the latter is for example a loudspeaker associated with an amplifier.

Dans l'exemple de réalisation particulier illustré sur les figures 1 à 3, la source d'énergie 6 est un barillet de sonnerie reçu dans un emplacement 12 du mécanisme 1 (le barillet de sonnerie 6 n'étant pas représenté sur les figures 1 et 2 pour des raisons de clarté). Le barillet de sonnerie 6 est typiquement un barillet à ressort, qui peut être armé en un seul geste par un utilisateur de la pièce d'horlogerie. Un tel barillet à ressort délivre en général un couple mécanique qui varie en fonction du désarmage du ressort. En variante non représentée, la source d'énergie 6 peut être un barillet du mouvement horloger mécanique de la pièce d'horlogerie, dont une partie de l'énergie emmagasinée est récupérée pour le mécanisme musical ou de sonnerie 1.In the particular embodiment illustrated on the figures 1 to 3 , the energy source 6 is a striking barrel received in a location 12 of the mechanism 1 (the striking barrel 6 not being shown in the figures 1 and 2 for clarity). Striking barrel 6 is typically a spring barrel, which can be cocked in a single gesture by a user of the timepiece. Such a spring barrel generally delivers a mechanical torque which varies according to the unwinding of the spring. In a variant not shown, the energy source 6 can be a barrel of the mechanical watch movement of the timepiece, part of the stored energy of which is recovered for the musical or striking mechanism 1.

Le régulateur 2 de mobile 4 est destiné à réguler le tempo de la sonnerie, ou de la mélodie selon le cas, du mécanisme 1. Dans l'exemple de réalisation particulier illustré sur les figures 1 à 3, le régulateur 2 de mobile 4 est destiné à réguler le tempo de la sonnerie du mécanisme de sonnerie 1. Plus précisément, le régulateur 2 est configuré pour réguler, autour d'une valeur de vitesse de consigne, la vitesse de pivotement du mobile 4 autour d'un axe de pivotement. Pour ce faire, le régulateur 2 comporte des moyens 14 de freinage du mobile 4 (qui seront décrits par la suite) configurés pour ramener la vitesse de pivotement du mobile 4 à la vitesse de consigne.The regulator 2 of mobile 4 is intended to regulate the tempo of the ringing, or of the melody as the case may be, of the mechanism 1. In the particular embodiment illustrated on the figures 1 to 3 , the regulator 2 of mobile 4 is intended to regulate the tempo of the ringing of the striking mechanism 1. More precisely, the regulator 2 is configured to regulate, around a set speed value, the pivoting speed of the mobile 4 around a pivot axis. To do this, the regulator 2 comprises means 14 for braking the mobile 4 (which will be described later) configured to bring the pivoting speed of the mobile 4 to the set speed.

Comme visible sur la figure 3, le régulateur 2 est constitué d'un système comprenant une génératrice électrique 16 et un circuit électronique 18 de régulation de la vitesse de rotation de la génératrice 16. La génératrice 16 est par exemple reliée au circuit électronique 18 via un circuit redresseur 19.As visible on the figure 3 , the regulator 2 consists of a system comprising an electric generator 16 and an electronic circuit 18 for regulating the speed of rotation of the generator 16. The generator 16 is for example connected to the electronic circuit 18 via a rectifier circuit 19.

Comme illustré sur la figure 3, la génératrice électrique 16 comporte un rotor 20 et un stator 22. Le rotor 20 est relié à la source d'énergie 6 délivrant le couple mécanique, via une chaîne cinématique non visible sur les figures (rouages et/ou train d'engrenages). Le stator 22 est par exemple formé d'un ensemble de bobines 24 reliées en série (une seule bobine 24 étant représentée sur la figure 3 pour des raisons de clarté). Les bobines 24 sont avantageusement des bobines sans fer, ce qui permet d'éviter tout couple de positionnement de départ. De préférence, la génératrice électrique 16 est une microgénératrice électro-dynamique. Lorsque le mécanisme 1 comporte un ou plusieurs composant(s) électrique(s) 10, ce dernier ou ces derniers peuvent être reliés directement ou indirectement à la génératrice électrique. Lorsqu'un des composants 10 au moins est un composant de stockage d'énergie électrique, l'énergie électrique accumulée dans ce composant peut notamment servir à alimenter le circuit électronique 18 lorsque la source d'énergie 6 ne délivre pas de couple mécanique.As shown on the figure 3 , the electric generator 16 comprises a rotor 20 and a stator 22. The rotor 20 is connected to the energy source 6 delivering the mechanical torque, via a kinematic chain not visible in the figures (cogs and / or gear train) . The stator 22 is for example formed of a set of coils 24 connected in series (a single coil 24 being shown in the figure. figure 3 for clarity). The coils 24 are advantageously coils without iron, which makes it possible to avoid any initial positioning torque. Preferably, the electric generator 16 is an electro-dynamic microgenerator. When the mechanism 1 comprises one or more electrical component (s) 10, the latter or these can be connected directly or indirectly to the generator electric. When at least one of the components 10 is an electrical energy storage component, the electrical energy accumulated in this component can in particular be used to power the electronic circuit 18 when the energy source 6 does not deliver a mechanical torque.

De préférence, le circuit électronique 18 est un circuit oscillateur. Dans l'exemple de réalisation particulier illustré sur les figures 1 à 3, le circuit électronique 18 comprend un circuit intégré 26 d'asservissement à technologie à semi-conducteur d'oxyde de métal complémentaire CMOS (de l'anglais Complementary Metal Oxide Semiconductor). Selon cet exemple de réalisation particulier, et comme illustré sur la figure 3, le circuit électronique 18 comprend également un quartz 28, qui est relié au circuit intégré 26 et qui fournit une fréquence de référence. En variante non représentée, le circuit électronique 18 comprend un circuit résistance inductance capacité configuré pour fournir une fréquence de référence.Preferably, the electronic circuit 18 is an oscillator circuit. In the particular embodiment illustrated on the figures 1 to 3 , the electronic circuit 18 comprises a servo integrated circuit 26 with complementary metal oxide semiconductor technology CMOS (standing for Complementary Metal Oxide Semiconductor). According to this particular embodiment, and as illustrated in figure 3 , the electronic circuit 18 also comprises a quartz 28, which is connected to the integrated circuit 26 and which provides a reference frequency. In a variant not shown, the electronic circuit 18 comprises a resistance-inductance-capacitance circuit configured to provide a reference frequency.

Le circuit intégré 26 présente une borne d'entrée 29 reliée à l'ensemble de bobines 24 de la génératrice 16 et permettant de récupérer un signal analogique 31 en provenance de cette dernière. Sans que cela ne soit limitatif dans le cadre de la présente invention, le circuit intégré 26 comprend par exemple une chaîne de divisions (incluant une logique de programmation d'inhibition), un comparateur à hystérèse de mise sous forme logique du signal analogique 31, un compteur réversible, ainsi qu'une logique de décision (de tels éléments n'étant pas représentés sur la figure 3 pour des raisons de clarté). Le circuit intégré comprend également un transistor 30, typiquement un transistor à effet de champ à grille isolée et à semiconducteur d'oxyde de métal MOS (de l'anglais Metal Oxide Semiconductor).The integrated circuit 26 has an input terminal 29 connected to the set of coils 24 of the generator 16 and making it possible to recover an analog signal 31 coming from the latter. Without this being limiting in the context of the present invention, the integrated circuit 26 comprises, for example, a chain of divisions (including inhibition programming logic), a hysteresis comparator for logical formatting of the analog signal 31, a reversible counter, as well as a decision logic (such elements not being represented on the figure 3 for clarity). The integrated circuit also comprises a transistor 30, typically an insulated gate field effect transistor with MOS metal oxide semiconductor (standing for Metal Oxide Semiconductor).

Le comparateur à hystérèse est relié à la borne d'entrée 29. La chaîne de divisions est connectée entre le quartz 28 et une entrée positive du compteur réversible. L'autre entrée du compteur réversible, qui est une entrée négative, est reliée à la sortie du comparateur à hystérèse. La logique de décision est connectée en sortie du compteur réversible, et présente une sortie de commande du transistor 30.The hysteresis comparator is connected to input terminal 29. The chain of divisions is connected between quartz 28 and a positive input of the reversible counter. The other input of the reversible counter, which is a negative input, is connected to the output of the hysteresis comparator. The logic decision is connected to the output of the reversible counter, and has a control output of transistor 30.

Le compteur réversible effectue la différence entre les deux signaux de type impulsionnel en provenance du quartz 28 d'une part, et de la génératrice 16 d'autre part, ainsi que l'intégration des impulsions au cours du temps. Le compteur réversible indique en outre l'avance ou le retard de la position angulaire du rotor 20 de la génératrice 16 par rapport à sa position angulaire idéale (donnée par le quartz 28) et la logique de décision qui suit le compteur décide de la consigne à établir. Cette logique de décision agit en fait en fonction de la valeur du compteur réversible (positive ou négative) et commande le transistor 30.The reversible counter performs the difference between the two pulse type signals coming from the quartz 28 on the one hand, and from the generator 16 on the other hand, as well as the integration of the pulses over time. The reversible counter also indicates the advance or the delay of the angular position of the rotor 20 of the generator 16 with respect to its ideal angular position (given by the quartz 28) and the decision logic which follows the counter decides on the setpoint. to establish. This decision logic acts in fact according to the value of the reversible counter (positive or negative) and controls the transistor 30.

Le transistor 30 est relié au stator 22 de la génératrice électrique 16. Plus précisément, comme illustré sur la figure 3, le transistor 30 est connecté en parallèle des bobines 24 via ses deux électrodes de drain et source. Le transistor 30 constitue les moyens de freinage 14, qui sont des moyens de freinage configurés pour freiner électriquement la rotation du rotor 20 de la génératrice 16.The transistor 30 is connected to the stator 22 of the electric generator 16. More precisely, as illustrated in the figure. figure 3 , the transistor 30 is connected in parallel with the coils 24 via its two drain and source electrodes. The transistor 30 constitutes the braking means 14, which are braking means configured to electrically brake the rotation of the rotor 20 of the generator 16.

Le circuit électronique 18 est ainsi configuré pour réguler, autour d'une vitesse de consigne, la vitesse de rotation de la génératrice 16, et pour ainsi freiner le mobile 4 de sorte à réguler sa vitesse de pivotement autour de l'axe de pivotement. La vitesse de consigne est par exemple égale à 7 tours par seconde, sans que cela ne soit limitatif dans le cadre de la présente invention. Ainsi, quel que soit le couple mécanique délivré par la source d'énergie 6, la génératrice électrique 16 tourne à vitesse constante ou quasi constante. Pour ce faire, la fréquence du signal en provenance de la génératrice 16 (qui est proportionnelle à la vitesse de rotation de cette dernière) est comparée à un sous-multiple de la fréquence de référence (fournie par le quartz 28 dans l'exemple de réalisation de la figure 3). Au besoin, la génératrice 16 est alors freinée électriquement par les moyens de freinage 14 que constitue le transistor 30, de manière à être asservie à la fréquence de référence fournie par le quartz 28. Pour ce faire le transistor 30, qui est piloté par la logique de décision du circuit intégré 26, court-circuite l'ensemble des bobines 24 du stator 22 pendant une fraction de la période de la tension alternative fournie par la génératrice 16. Le transistor 30 agit alors comme un moyen de freinage intermittent et impulsionnel du rotor 20 de la génératrice 16.The electronic circuit 18 is thus configured to regulate, around a set speed, the speed of rotation of the generator 16, and thus to brake the mobile 4 so as to regulate its pivot speed around the pivot axis. The setpoint speed is for example equal to 7 revolutions per second, without this being limiting in the context of the present invention. Thus, whatever the mechanical torque delivered by the energy source 6, the electric generator 16 rotates at constant or almost constant speed. To do this, the frequency of the signal coming from the generator 16 (which is proportional to the speed of rotation of the latter) is compared to a sub-multiple of the reference frequency (supplied by the quartz 28 in the example of realization of the figure 3 ). If necessary, the generator 16 is then electrically braked by the braking means 14 formed by the transistor 30, so as to be slaved to the reference frequency supplied. by the quartz 28. To do this, the transistor 30, which is driven by the decision logic of the integrated circuit 26, short-circuits all of the coils 24 of the stator 22 during a fraction of the period of the alternating voltage supplied by the generator 16. The transistor 30 then acts as an intermittent and pulsed braking means of the rotor 20 of the generator 16.

En fonctionnement, lorsque le rotor 20 de la génératrice 16 est mû sous l'effet d'un couple fourni par le ressort du barillet 6, une tension alternative induite apparaît aux bornes de l'ensemble de bobines 24 du stator 22. La tension alternative induite est alors utilisée pour deux fonctions : en premier lieu cette tension est redressée via le circuit redresseur 19 et permet d'alimenter le circuit intégré 26, et en second lieu cette tension permet de fournir une source d'énergie électrique disponible pour la pièce d'horlogerie. Cette source d'énergie électrique rechargeable permet alors, par exemple, d'alimenter le ou les composant(s) électrique(s) 10. L'énergie électrique accumulée peut ensuite être avantageusement réutilisée par un composant électrique, tel qu'une diode électroluminescente pour illuminer des éléments de la pièce d'horlogerie, tels que des timbres, des marteaux ou des aiguilles par exemple, ou encore par un composant de génération de son ou de vibrations au sein du mécanisme.In operation, when the rotor 20 of the generator 16 is moved under the effect of a torque supplied by the spring of the barrel 6, an induced alternating voltage appears at the terminals of the set of coils 24 of the stator 22. The alternating voltage induced is then used for two functions: firstly this voltage is rectified via the rectifier circuit 19 and makes it possible to supply the integrated circuit 26, and secondly this voltage makes it possible to provide a source of electrical energy available for the part d watchmaking. This rechargeable electrical energy source then makes it possible, for example, to supply the electrical component (s) 10. The accumulated electrical energy can then be advantageously reused by an electrical component, such as a light emitting diode. to illuminate elements of the timepiece, such as gongs, hammers or hands for example, or even by a component for generating sound or vibrations within the mechanism.
