- the method of tuning a timbre consists of targeting a note at a given frequency and the other partials obtained are dependent on the target frequency. For example, for the tuning of the 5N gold timbre to the note Si, the length of the timbre is retouched to best approach the target frequency of 1975.5 Hz. Other frequencies are also generated when typing. These frequency modes will be different, for example depending in particular on the geometry and the material of the stamp.
- a rich sound is characterized by many modes in the audible frequency range while a poor sound will have fewer frequency modes in the audible frequency range and will appear more crystalline.
- a rich sound can therefore be very pleasing to the ear, but there will be a higher chance of having dissonances if several notes with a rich sound are played in succession.
- the method of mixing material would make it possible to avoid this kind of dissonance.
- a timbre, as defined below, in 5N gold tuned to generate the note Si at 1975.5 Hz may for example have a spectrum as shown in figure 5a .
- the height of the peaks is not representative.
- a timbre, as defined below, in 5N gold tuned to generate the Fa # note at 2960 Hz may for example have a spectrum as shown in figure 5b .
- the height of the peaks is not representative.
- a timbre, as defined below, made of steel tuned to generate the note Fa # at 2960 Hz may for example have a spectrum as shown in figure 5c .
- the height of the peaks is not representative.
- a steel gong could therefore be used to play successively the note B on a gold gong and F on a steel gong.
- This example gives a concrete vision of the use of this mixing method but is not limited to that.
- the acoustic analysis and the feeling of the human ear will be preponderant on the detection of dissonance. Indeed, in the example above, certain frequencies leading to dissonances cannot be heard by the ear. In other words, it is mainly the human ear that will detect these dissonances, which can be avoided by a mixture of the materials of the stamp.
- the size of the stamps can also avoid dissonance phenomena.
- stamp of square cross section of a first area for example 0.5 mm x 0.5 mm
- stamp of square cross section of a second area for example 0.65 mm x 0.65 mm
- stamp of square cross section on the first surface for example 0.5 mm x 0.5 mm
- stamp of square cross section on the second surface for example 0.65 mm x 0.65 mm connected to the same holder. stamp or two different stamp holders.

Description
L'invention concerne un ensemble d'au moins deux timbres reliés à au moins un porte-timbre pour un mécanisme de sonnerie d'une montre. Chaque timbre doit être conçu avec un matériau particulier pour tenir compte aussi de l'encombrement à disposition dans la boîte de montre tout en garantissant une génération d'un son riche lors de la frappe de chaque timbre.The invention relates to a set of at least two gongs connected to at least one gong holder for a striking mechanism of a watch. Each gong must be designed with a particular material to also take into account the space available in the watch case while ensuring that a rich sound is generated when each gong is struck.
Dans le domaine de l'horlogerie, un mouvement horloger peut être muni d'un mécanisme de sonnerie. Pour ce faire, au moins un timbre, qui est un fil métallique de forme circulaire par exemple en acier, peut être prévu. Généralement, ce fil métallique est disposé autour du mouvement, dans la boîte de montre. Ce timbre est fixé, par exemple par soudure ou brasure, à un porte-timbre, qui est lui-même solidaire de la platine ou de la carrure de la boîte de montre. La vibration du timbre est produite par l'impact généralement à proximité du porte-timbre d'au moins un marteau. Cette vibration est composée de plusieurs fréquences propres ou partiels, dont le nombre et l'intensité, en particulier dans le domaine audible entre 1 kHz et 20 kHz, dépendent de la géométrie du timbre et des propriétés physiques du matériau utilisé. Les partiels sont définis dans le cas où les fréquences supérieures à la fondamentale ne sont plus des multiples entiers de la fréquence la plus basse.In the field of watchmaking, a watch movement can be provided with a striking mechanism. To do this, at least one stamp, which is a metal wire of circular shape, for example made of steel, can be provided. Generally, this metal wire is placed around the movement, in the watch case. This stamp is fixed, for example by soldering or brazing, to a stamp holder, which is itself integral with the plate or the middle part of the watch case. The vibration of the gong is produced by the impact generally near the gong holder of at least one hammer. This vibration is made up of several natural or partial frequencies, the number and intensity of which, in particular in the audible range between 1 kHz and 20 kHz, depend on the geometry of the timbre and the physical properties of the material used. Partials are defined in the case where frequencies above the fundamental are no longer whole multiples of the lowest frequency.

L'invention a donc pour but de pallier les inconvénients de l'état de la technique en fournissant un ensemble de timbres pour un mécanisme de sonnerie d'une montre et susceptible de supprimer tout problème de dissonance lors de l'accordage des timbres ou lors de la succession de sons de timbres successivement frappés par au moins un marteau du mécanisme de sonnerie.The object of the invention is therefore to overcome the drawbacks of the state of the art by providing a set of gongs for a striking mechanism of a watch and capable of eliminating any problem of dissonance during the tuning of gongs or during gongs. of the estate of sounds of stamps successively struck by at least one hammer of the striking mechanism.
A cet effet, l'invention concerne un ensemble de timbres comprenant les caractéristiques définies dans la revendication indépendante 1.To this end, the invention relates to a set of stamps comprising the characteristics defined in
Des formes d'exécution particulières de l'ensemble de timbres sont définies dans les revendications dépendantes 2 à 17.Particular embodiments of the set of stamps are defined in
Un avantage de l'ensemble de timbres réside dans le fait qu'il comprend au moins deux timbres reliés à au moins un porte-timbre, et qui sont réalisés chacun avec un matériau différent. Chaque timbre est configuré pour générer une note particulière et la réalisation de ces timbres ou groupe de timbres dans des matériaux différents permet d'éviter toute dissonance notamment déjà lors de l'accordage des timbres. Dans le cas, d'un ensemble à quatre timbres, dont deux timbres peuvent être reliés chacun à leur propre porte-timbre, alors que les deux autres timbres peuvent être reliés à un même porte-timbre, l'emploi de matériaux différents permet de viser des notes précises pour obtenir une mélodie en supprimant toute dissonance notamment lors de l'accordage des timbres.An advantage of the set of stamps lies in the fact that it comprises at least two stamps connected to at least one stamp holder, and which are each made with a different material. Each timbre is configured to generate a particular note and the realization of these timbres or group of timbres in different materials makes it possible to avoid any dissonance, especially already during the tuning of the timbres. In the case of a set of four stamps, of which two stamps can each be connected to their own stamp holder, while the other two stamps can be linked to the same stamp holder, the use of different materials makes it possible to aim for precise notes to obtain a melody by eliminating any dissonance, especially when tuning timbres.
Avantageusement, chaque timbre relié à chaque porte-timbre respectif et un groupe d'au moins deux timbres reliés à un même porte-timbre peuvent être réalisés chacun sous forme monobloc. Par exemple, un premier timbre relié à un premier porte-timbre sont réalisés en une pièce sous forme monobloc, de même pour un second timbre relié à un second porte-timbre. Le groupe de deux timbres reliés à un même porte-timbre est aussi réalisé en une pièce sous forme monobloc. Ainsi, les porte-timbres peuvent être chacun sous forme d'une plaquette d'épaisseur équivalente à chaque timbre. Ils peuvent être vissés par exemple sur une platine de mouvement de montre facilement et sans trop d'encombrement. Ils peuvent aussi être vissés de préférence sur un rebord de la carrure de la boîte de montre pour réduire l'encombrement dans l'espace réduit de la boîte de montre.Advantageously, each stamp connected to each respective stamp holder and a group of at least two stamps connected to the same stamp holder can each be produced in one-piece form. For example, a first stamp connected to a first stamp holder are produced in one piece in monobloc form, the same for a second stamp connected to a second stamp holder. The group of two stamps connected to the same stamp holder is also produced as a single piece in monobloc form. Thus, the stamp holders can each be in the form of a plate of thickness equivalent to each stamp. They can be screwed for example on a watch movement plate easily and without too much space. They can also preferably be screwed onto a rim of the middle part of the watch case to reduce the bulk in the small space of the watch case.

Il est à noter qu'il peut aussi être prévu un ensemble à quatre timbres où chaque timbre est relié à son propre porte-timbre et où chaque timbre est réalisé dans un matériau différent de chaque autre timbre. De plus, il peut aussi être envisagé que chaque timbre relié à son propre porte-timbre ne forme qu'une pièce sous forme monobloc.It should be noted that a set of four stamps can also be provided where each stamp is connected to its own stamp holder and where each stamp is made of a material different from each other stamp. In addition, it can also be envisaged that each gong connected to its own gong holder forms only one piece in one-piece form.
La théorie de l'acoustique et le phénomène de dissonance sont expliqués ci-après pour bien comprendre la présente invention avec la réalisation des timbres dans des matériaux différents.The theory of acoustics and the phenomenon of dissonance are explained below to fully understand the present invention with the realization of the timbres in different materials.
Il existe un demi-ton entre chaque note successive composant une gamme. On peut qualifier l'intervalle entre deux notes selon le nombre de demi-tons qu'il y a entre les deux notes. Par exemple un écart d'un demi-ton entre deux notes s'appelle une seconde mineure, par exemple entre le do et le do# ou encore entre le mi et le fa. Un écart de sept demi-tons entre deux notes s'appelle une quinte juste. Certains intervalles sont agréables à entendre, on dira qu'ils sont consonants. D'autres intervalles ne sont pas agréables à entendre, on dira qu'ils sont dissonants.There is a semitone between each successive note making up a scale. We can qualify the interval between two notes according to the number of semitones between the two notes. For example, a semitone difference between two notes is called a minor second, for example between C and C # or between E and F. A difference of seven semitones between two notes is called a perfect fifth. Certain intervals are pleasant to hear, we will say that they are consonant. Other intervals are not pleasant to hear, we will say that they are dissonant.
On classe habituellement les intervalles du plus consonant au plus dissonant dans l'ordre suivant : unisson, octave, quinte juste, quarte juste, tierce majeure, sixte majeure, tierce mineure, sixte mineure, septième mineure, seconde majeure, triton, septième majeure, puis seconde mineure.We usually classify the intervals from most consonant to most dissonant in the following order: unison, octave, perfect fifth, perfect fourth, major third, major sixth, minor third, minor sixth, minor seventh, major second, tritone, major seventh, then minor second.
Une note correspond à une fréquence fondamentale qui peut se déterminer par la formule suivante :
- fn : Fréquence de la note voulue,
- f0: Fréquence de la note de référence (le La3 à 440 Hz dans la gamme tempérée)
- n: Demi-ton au-dessus de la note
- fn : Frequency of the desired note,
- f 0: Frequency of the reference note (A3 at 440 Hz in the tempered range)
- n : Semitone above the note
Cela donne les fréquences suivantes en Hertz selon les différentes octaves :
Un exemple d'utilisation de la méthode de panachage est donné ci-après.An example of the use of the mixing method is given below.
Pour une montre à carillon, la recherche de notes précises est nécessaire pour construire une mélodie agréable à l'oreille. La méthode d'accordage d'un timbre consiste à viser une note à une fréquence donnée et les autres partiels obtenus sont dépendant de la fréquence visée. Par exemple, pour l'accordage du timbre en or 5N à la note Si, la longueur du timbre est retouchée pour s'approcher au mieux de la fréquence de 1975.5 Hz visée. D'autres fréquences sont également générées lors de la frappe. Ces modes fréquentiels seront différents par exemple selon notamment la géométrie, la matière du timbre.For a chime watch, the search for precise notes is necessary to build a melody pleasing to the ear. The method of tuning a timbre consists of targeting a note at a given frequency and the other partials obtained are dependent on the target frequency. For example, for the tuning of the 5N gold timbre to the note Si, the length of the timbre is retouched to best approach the target frequency of 1975.5 Hz. Other frequencies are also generated when typing. These frequency modes will be different, for example depending in particular on the geometry and the material of the stamp.
La succession de deux notes consécutives peut conduire à des dissonances si les différents partiels ne s'accordent pas. Par exemple, il est bien connu qu'une seconde mineure, c'est-à-dire un écart d'un demi-ton entre deux notes, est très dissonante. Un écart d'un demi-ton se retrouve par exemple entre la note "la" et la note "la#" ou entre la note "si" et la note "do". Cela signifie que deux notes séparées d'un demi-ton jouées en même temps ou successivement paraîtront dissonantes à l'oreille.The succession of two consecutive notes can lead to dissonances if the different partials do not agree. For example, it is well known that a minor second, that is, a semitone difference between two notes, is very dissonant. A semitone difference is found for example between the note "a" and the note "la #" or between the note "si" and the note "do". This means that two notes separated by a semitone played at the same time or in succession will sound dissonant to the ear.
Ensuite, un son riche se caractérise par de nombreux modes dans la gamme de fréquences audibles alors qu'un son pauvre aura moins de modes fréquentiels dans la gamme de fréquences audibles et paraîtra plus cristallin. Un son riche peut donc être très agréable à l'oreille, mais il y aura de plus fortes chances d'avoir des dissonances, si plusieurs notes avec un son riche sont jouées successivement. La méthode de panachage de matière permettrait d'éviter ce genre de dissonance.Then, a rich sound is characterized by many modes in the audible frequency range while a poor sound will have fewer frequency modes in the audible frequency range and will appear more crystalline. A rich sound can therefore be very pleasing to the ear, but there will be a higher chance of having dissonances if several notes with a rich sound are played in succession. The method of mixing material would make it possible to avoid this kind of dissonance.
Par exemple, on peut prendre un matériau comme l'or, qui est connu pour générer des sons riches. Un timbre, comme défini ci-après, en or 5N accordé pour générer la note Si à 1975.5 Hz peut par exemple avoir un spectre comme représenté à la
Si l'on considère les modes fréquentiels intéressants pour la construction d'une mélodie entre 1000Hz et 10000Hz, on remarque que pour la succession par exemple des notes Si et Fa en or 5N, il y a 4 modes qui sont dissonants. Lors d'une mélodie, un amortissement faible des notes peut être recherché. Dans ce cas, générer successivement les notes Si et Fa sur deux timbres en or 5N pourront générer 4 secondes mineures (cf. tableau ci-dessous), ce qui est dissonant.
Ainsi, dans cet exemple, si l'on joue successivement deux notes, Si et Fa#, le panachage de matières des deux timbres en or 5N et acier permet d'éviter les dissonances que l'on génère avec deux timbres en or.Thus, in this example, if two notes are played successively, B and F #, the mixture of materials of the two 5N gold and steel stamps makes it possible to avoid the dissonances that are generated with two gold stamps.
Cet exemple donne une vision concrète de l'utilisation de cette méthode de panachage mais ne se limite pas à cela. L'analyse acoustique et le ressenti de l'oreille humaine seront prépondérants sur la détection de dissonance. En effet, dans l'exemple ci-dessus, certaines fréquences menant à des dissonances ne s'entendent pas à l'oreille. En d'autres mots, c'est principalement l'oreille humaine qui détectera ces dissonances, que l'on pourra éviter grâce à un panachage des matières de timbre.This example gives a concrete vision of the use of this mixing method but is not limited to that. The acoustic analysis and the feeling of the human ear will be preponderant on the detection of dissonance. Indeed, in the example above, certain frequencies leading to dissonances cannot be heard by the ear. In other words, it is mainly the human ear that will detect these dissonances, which can be avoided by a mixture of the materials of the stamp.
En plus du panachage de matière, il est envisageable de panacher aussi la dimension des timbres pour éviter également des phénomènes de dissonances. Par exemple, il est possible de jouer sur la forme et la dimension des sections des timbres. Il est possible d'assembler un timbre de section transversale ronde et un timbre de section transversale carrée. Il est possible aussi d'avoir un timbre de section transversale ronde et un timbre de section transversale carrée reliés à un même porte-timbre ou à deux porte-timbres différents. Il est possible aussi d'assembler un timbre de section transversale ronde à un timbre de section transversale ronde de diamètre différent, ou d'avoir les timbres de section transversale ronde reliés à un même porte-timbre ou à deux porte-timbres différents. Il est possible aussi d'assembler un timbre de section transversale carrée d'une première surface, par exemple 0.5 mm x 0.5 mm avec un timbre de section transversale carrée d'une seconde surface, par exemple 0.65 mm x 0.65 mm. Il est possible encore d'avoir un timbre de section transversale carrée à la première surface, par exemple 0.5 mm x 0.5 mm et un timbre de section transversale carrée à la seconde surface, par exemple 0.65 mm x 0.65 mm reliés à un même porte-timbre ou à deux porte-timbres différents.In addition to the mixing of material, it is also possible to envisage mixing the size of the stamps to also avoid dissonance phenomena. For example, it is possible to play with the shape and size of the sections of the stamps. It is possible to assemble a stamp of round cross section and a stamp of square cross section. It is also possible to have a stamp of round cross section and a stamp of square cross section connected to the same stamp holder or to two different stamp holders. It is also possible to assemble a stamp of round cross section to a stamp of round cross section of different diameter, or to have the stamps of round cross section connected to the same stamp holder or to two different stamp holders. It is also possible to assemble a stamp of square cross section of a first area, for example 0.5 mm x 0.5 mm with a stamp of square cross section of a second area, for example 0.65 mm x 0.65 mm. It is also possible to have a stamp of square cross section on the first surface, for example 0.5 mm x 0.5 mm and a stamp of square cross section on the second surface, for example 0.65 mm x 0.65 mm connected to the same holder. stamp or two different stamp holders.
Bien entendu d'autres valeurs dimensionnelles des timbres peuvent être appliquées en fonction de la dimension de la montre équipée du mécanisme de sonnerie.Of course, other dimensional values of the gongs can be applied depending on the size of the watch equipped with the striking mechanism.
A partir de la description qui vient d'être faite, plusieurs variantes de l'ensemble de timbres pour un mécanisme de sonnerie d'une montre peuvent être conçues par l'homme du métier sans sortir du cadre de l'invention définie par les revendications.From the description which has just been given, several variants of the set of gongs for a striking mechanism of a watch can be designed by those skilled in the art without departing from the scope of the invention defined by the claims. .
