Description

Domaine techniqueTechnical area

La présente invention concerne un accordeur chromatique pour instruments de musique, mesurant la fréquence sonore produite par l'instrument à accorder, et affichant sur une montre des grandeurs caractérisant la justesse de l'accordage, par exemple une montre bracelet.The present invention relates to a chromatic tuner for musical instruments, measuring the sound frequency produced by the instrument to be tuned, and displaying on a watch magnitudes characterizing the accuracy of the tuning, for example a wristwatch.

Etat de la techniqueState of the art

Les instruments de musique nécessitent en général un accordage périodique, afin d'assurer la constance des sons qu'ils produisent. Pour ce faire, une technique courante consiste à employer un diapason, qui donne le LA, note de référence de la quatrième octave à 440 Hertz.Musical instruments usually require periodic tuning to ensure the consistency of the sounds they produce. To do this, a common technique is to use a tuning fork, which gives the LA, reference note of the fourth octave at 440 Hertz.

Afin de garantir de garantir l'exactitude de la justesse de la note indépendamment de paramètres altérant les caractéristiques d'un diapason, tels que l'humidité et la température, il existe désormais des accordeurs électroniques, dont la précision est plus fine pour déterminer la fréquence à associer à une note. Ces accordeurs contiennent d'une part un microphone, convertissant le signal acoustique en un signal électrique, et un dispositif d'affichage numérique indiquant la note la plus proche ainsi que la justesse par rapport à cette note en fonction du signal acoustique détecté et du signal électrique obtenu.In order to guarantee the correctness of the accuracy of the note independently of parameters altering the characteristics of a tuning fork, such as humidity and temperature, there are now electronic tuners, whose precision is finer to determine the frequency to associate with a note. These tuners contain on the one hand a microphone, converting the acoustic signal into an electrical signal, and a digital display device indicating the closest note and the accuracy of this note according to the detected acoustic signal and the signal. electric obtained.

Certains accordeurs sont calibrés sur une fréquence de référence fixe, typiquement 440Hz; d'autres peuvent toutefois être réglés sur une fréquence voisine afin d'adapter la sonorité de l'instrument à des conditions acoustiques particulières, comme par exemple des propriétés de résonance d'un bâtiment ou d'une salle de concert.Some tuners are calibrated on a fixed reference frequency, typically 440Hz; others can however be set to a neighboring frequency in order to adapt the sound of the instrument to particular acoustic conditions, such as the resonance properties of a building or a concert hall.

Un inconvénient des accordeurs chromatiques électroniques portables est qu'ils sont souvent relativement encombrants, et que le musicien risque ainsi de les oublier ou de les perdre. Par ailleurs, l'affichage numérique ne permet pas une lecture intuitive des indications fournies, notamment par rapport à la justesse de la note et les réglages, tant lors de l'opération de calibrage que lors de l'accordage lui-même.A disadvantage of portable electronic color tuners is that they are often relatively bulky, and the musician may forget them or lose them. Moreover, the digital display does not allow an intuitive reading of the indications provided, especially with respect to the accuracy of the note and the settings, both during the calibration operation and during the tuning itself.

On connaît par ailleurs, du document JP2153393 , une pièce d'horlogerie portable qui permet d'afficher des informations sur la fréquence d'une note. Ce document décrit les caracteristiques du préambule de la revendication 1. Cette solution est toutefois malcommode pour une lecture simultanée d'informations sur la hauteur des notes et leur justesse, car les aiguilles peuvent être quasiment superposées et concentrer toutes les informations utiles dans une zone restreinte du cadran.In addition, document JP2153393 , a portable timepiece that displays information about the frequency of a note. This document describes the features of the preamble of claim 1. However, this solution is inconvenient for simultaneous reading of information on the pitch of the notes and their accuracy, because the needles can be almost superimposed and concentrate all the useful information in a restricted area. of the dial.

Il existe donc un besoin pour un accordeur chromatique exempt de ces limitations de l'art antérieur.There is therefore a need for a chromatic tuner free of these limitations of the prior art.

Bref résumé de l'inventionBrief summary of the invention

Exemples de modes de réalisation de l'inventionExamples of embodiments of the invention

L'invention concerne une pièce d'horlogerie portable, typiquement une montre bracelet, mais par exemple également un pendentif, une montre à gousset, ou tout autre dispositif d'affichage de l'heure portatif, avec un accordeur chromatique intégré qui utilise une ou plusieurs aiguilles de la montre, d'ordinaire dédiées à l'affichage de l'heure courante. Une telle pièce d'horlogerie comprend par conséquent implicitement un mode accordage distinct du mode d'affichage usuel des heures, et dans lequel au moins une des aiguilles n'est plus utilisées à cette fin. L'accordeur comporte un module électronique pour le calcul de la valeur des fréquences sonores émises par l'instrument à accorder, et cette valeur ainsi que la justesse de cette fréquence par rapport à des notesThe invention relates to a portable timepiece, typically a wristwatch, but for example also a pendant, a gusset watch, or any other portable time display device, with an integrated chromatic tuner that uses one or more hands of the watch, usually dedicated to the display of the current time. Such a timepiece therefore implicitly comprises a tuning mode distinct from the usual display mode hours, and wherein at least one of the needles is no longer used for this purpose. The tuner comprises an electronic module for calculating the value of the sound frequencies emitted by the instrument to be tuned, and this value and the accuracy of this frequency with respect to notes

d'une gamme, par exemple la gamme tempérée (do, do#, ré, ré#, mi, fa, fa#, sol, sol#, la, la#, si, pour laquelle la fréquence de référence est celle du la à 440Hz) est affichée sur la pièce d'horlogerie. La notation anglo-saxonne pour la gamme tempérée fait correspondre aux notes "la" la valeur A, "si" la valeur B, "do" la valeur C, "ré" la valeur D, "mi" la valeur E, "fa" la valeur F et "sol" la valeur G, comme on le verra plus tard sur les dispositifs d'affichage selon des modes de réalisation préférentiels de l'invention. L'homme du métier comprendra qu'il est envisageable d'adapter l'accordeur intégré selon l'invention à n'importe quel type de gamme (naturelle, pythagoricienne) et n'importe quel système tonique.of a range, for example the temperate range (do, do #, re, re #, mi, fa, fa #, sol, sol #, la, the #, if, for which the reference frequency is that of the at 440Hz) is displayed on the timepiece. The Anglo-Saxon notation for the temperate range corresponds to the notes "la" the value A, "if" the value B, "do" the value C, "re" the value D, "mi" the value E, "fa "the value F and" ground "the value G, as will be seen later on the display devices according to preferred embodiments of the invention. Those skilled in the art will understand that it is conceivable to adapt the integrated tuner according to the invention to any type of range (natural, Pythagorean) and any tonic system.

La figure 1 illustre les éléments logiques et fonctionnels du dispositif électronique 100 utilisé dans le cadre d'une variante préférentielle de l'invention. Selon cette variante, le dispositif électronique 100 comporte tout d'abord un capteur de signal acoustique 101, c'est-à-dire un microphone, qui capte donc les ondes acoustiques du milieu extérieur. Le signal électroacoustique 10 reçu est ensuite transmis à des moyens de traitement du signal 102, qui transforment le signal électroacoustique 10 du microphone en un train d'impulsions 108, dont les changements d'états sont provoqués par des changements de signe du signal électroacoustique 10 du microphone. Le train d'impulsions 108 est donc un signal binaire, par opposition au signal électroacoustique 10 qui est un signal analogique.The figure 1 illustrates the logical and functional elements of the electronic device 100 used in the context of a preferred embodiment of the invention. According to this variant, the electronic device 100 firstly comprises an acoustic signal sensor 101, that is to say a microphone, which thus captures the acoustic waves of the external medium. The received electroacoustic signal 10 is then transmitted to signal processing means 102, which transforms the electroacoustic signal 10 of the microphone into a pulse train 108, whose changes of state are caused by sign changes of the electroacoustic signal 10. microphone. The pulse train 108 is therefore a binary signal, as opposed to the electroacoustic signal 10 which is an analog signal.

Les moyens de traitement du signal 102 se composent d'un filtre 1021, qui élimine des composantes de fréquence en dehors d'une bande-passante de signal déterminée. Le signal 10 est ensuite transmis à un amplificateur 1022 et à un comparateur 1023, comme par exemple un comparateur à hystérèse de type Trigger de Schmitt.The signal processing means 102 consist of a filter 1021, which eliminates frequency components outside a determined signal bandwidth. The signal 10 is then transmitted to an amplifier 1022 and a comparator 1023, such as for example a hysteresis comparator of the Schmitt Trigger type.

Le train d'impulsions 108 est transmis à une des interfaces d'entrée/sortie d'un microcontrôleur 103, dont l'ensemble est référencé par le numéro 115 dans un souci de simplification. Le microcontrôleur 103 dispose par ailleurs d'au moins une sortie pour délivrer un courant d'alimentation 106 des moyens de traitement du signal 102, d'une batterie 107, d'un oscillateur à quartz 104, typiquement de 32KHz et dont la fréquence est compensée en température, puis corrigée périodiquement par inhibition. Le microcontrôleur 103 intègre également un oscillateur RC 105 de préférence de 4 MHz, ce qui permet de commuter l'horloge du processeur 113 du microcontrôleur 103 sur une fréquence plus rapide lorsque de longs calculs ou des mesures rapides doivent être effectuées, principalement durant l'activation de la fonction accordeur.The pulse train 108 is transmitted to one of the input / output interfaces of a microcontroller 103, the whole of which is referenced by the number 115 for the sake of simplification. The microcontroller 103 also has at least one output for delivering a supply current 106 of the signal processing means 102, a battery 107, a crystal oscillator 104, typically 32KHz and whose frequency is temperature compensated and periodically corrected by inhibition. The microcontroller 103 also incorporates an RC oscillator 105 preferably of 4 MHz, which makes it possible to switch the clock of the processor 113 of the microcontroller 103 to a faster frequency when long calculations or rapid measurements have to be made, mainly during the activation of the tuner function.

Comme illustré sur la figure 1, le dispositif électronique 100 comprend par ailleurs des moyens d'interface utilisateur 112, consistant par exemple, selon les variantes préférentielles de l'invention illustrées notamment par les figures 3 et 4, en des boutons poussoirs (référencés 16, 17, 18 sur ces figures). Ces moyens d'interface utilisateur 112 peuvent toutefois également consister en une tige couronne (référencée par exemple sur les figures 5 à 7 par le chiffre 9), ou encore une glace tactile, cette dernière variante n'étant toutefois pas illustrée. Ces moyens d'interface utilisateur 112 permettent d'interagir avec l'utilisateur notamment pour requérir un changement de mode, effectuer des réglages et valider ces réglages, comme on le verra plus tard. Ils interagissent sur une interface d'entrée/sortie 115 du microcontrôleur 103.As illustrated on the figure 1 the electronic device 100 further comprises user interface means 112, consisting for example of the preferred embodiments of the invention illustrated in particular by the Figures 3 and 4 , push buttons (referenced 16, 17, 18 in these figures). These user interface means 112 may however also consist of a crown rod (referenced for example on the Figures 5 to 7 by the number 9), or a touch screen, the latter variant is however not illustrated. These user interface means 112 make it possible to interact with the user in particular to request a change of mode, to make adjustments and to validate these adjustments, as will be seen later. They interact on an input / output interface 115 of the microcontroller 103.

Le dispositif électronique 100 comprend par ailleurs, selon le mode de réalisation préférentiel illustré par la figure 1, un module moteur 114 composé d'au moins un moteur bidirectionnel, associé à des moyens d'affichage analogique 111. Les moyens d'affichage analogique 111 comprennent au moins une aiguille indépendante permettant d'afficher des informations sur le signal reçu, l'aiguille étant soit celle des heures 3 soit celle des minutes 2, comme on le verra sur les figures 3 à 7 qui illustrent différents dispositifs d'affichage selon divers modes de réalisation de l'invention.The electronic device 100 furthermore comprises, according to the preferred embodiment illustrated by the figure 1 , a motor module 114 composed of at least one bi-directional motor, associated with analog display means 111. The analog display means 111 comprise at least one independent needle for displaying information on the received signal, the needle being either hours 3 or minutes 2, as will be seen on the Figures 3 to 7 which illustrate different display devices according to various embodiments of the invention.

La pièce d'horlogerie 1 avec accordeur chromatique intégré selon l'invention englobe des systèmes d'affichage totalement analogiques, ou hybrides avec affichage partiellement numérique.Timepiece 1 with integrated chromatic tuner according to the invention includes fully analog display systems, or hybrid with partially digital display.

Selon le premier système d'affichage, le module moteur 114 du dispositif électronique 100 agit indépendamment sur les deux aiguilles des heures 3 et des minutes 2 de la pièce d'horlogerie 1 afin de donner respectivement une information sur la note identifiée pour le signal électroacoustique 10, et une information sur la précision par rapport à cette note.According to the first display system, the motor module 114 of the electronic device 100 acts independently on the two hands of the hours 3 and minutes 2 of the timepiece 1 to respectively give information on the note identified for the electroacoustic signal 10, and information on the accuracy with respect to this note.

La figure 2 illustre le processus 20 d'identification des notes et de leur justesse selon une variante préférentielle de l'accordeur chromatique de l'invention.The figure 2 illustrates the process of identifying notes and their correctness according to a preferred variant of the chromatic tuner of the invention.

Selon ce mode de réalisation préférentiel, l'oscillateur RC 105 est tout d'abord calibré dans une étape 201, car la fréquence de celui-ci varie dans le temps en fonction de la tension d'alimentation et de la température. La calibration consiste à compter le nombre de coups d'horloge de l'oscillateur RC 105 dans une fenêtre de temps fixée par la période d'un signal dérivé de l'horloge de base 104 compensée en température. La calibration est effectuée périodiquement, par exemple aux secondes 3 et 33, afin d'assurer une stabilité de la mesure de fréquence du signal acoustique. De la calibration de l'oscillateur résulte le facteur de correction 25 pour compenser les fréquences déterminées lors du processus d'identification des notes.According to this preferred embodiment, the RC oscillator 105 is first calibrated in a step 201, because the frequency thereof varies over time as a function of the supply voltage and the temperature. The calibration consists in counting the number of clock strokes of the oscillator RC 105 in a time window set by the period of a signal derived from the base clock 104 compensated in temperature. Calibration is carried out periodically, for example at seconds 3 and 33, in order to ensure stability of the frequency measurement of the acoustic signal. Oscillator calibration results in the correction factor to compensate for the frequencies determined during the note identification process.

L'étape 202 consiste en l'exécution, par le microcontrôleur 103, non représenté sur la figure 2, d'un processus de mesure du signal binaire 108 obtenu en sortie des moyens de traitement du signal électroacoustique 102, en comptant le temps entre chaque flanc montant de ce signal 102 et en mémorisant successivement chaque période du signal 22 dans la mémoire de données 109. Les périodes acquises par le microcontrôleur forment la série 231, qui est ensuite comparée à un seuil, initialement défini par exemple par la valeur maximale de la série 231, lors de l'étape 2031. Les indices des échantillons dont la valeur est supérieure au seuil forment ensuite la série réduite 232, entre lesquels on calcule la durée entre chaque élément lors de l'étape 2032. Ces durées forment la série 233, qui est triée lors de l'étape 2033 dans l'ordre croissant pour former la série 234.Step 202 consists of the execution, by the microcontroller 103, not represented on the figure 2 of a process for measuring the binary signal 108 obtained at the output of the electroacoustic signal processing means 102, by counting the time between each rising edge of this signal 102 and successively memorizing each period of the signal 22 in the data memory 109 The periods acquired by the microcontroller form the series 231, which is then compared with a threshold, initially defined for example by the maximum value of the series 231, during step 2031. The indices of the samples whose value is greater than threshold then form the reduced series 232, between which the duration between each element is calculated during step 2032. These durations form the series 233, which is sorted during step 2033 in ascending order to form the series 234 .

L'étape d'identification 204 de la période fondamentale du signal électroacoustique 10 est ensuite déterminée en cherchant une relation périodique entre les éléments de la série 234. Le processus part du plus petit élément de la série puis cherche des multiples de cet élément en parcourant la série dans l'ordre croissant. Chaque élément de la série est divisé par des nombres entiers croissants jusqu'à approcher de l'élément le plus petit. Dès qu'un élément de la série avoisine un multiple de cet élément le plus petit, alors cet élément est considéré comme étant la période fondamentale du signal ; si par contre aucun multiple n'est trouvé le processus est réitéré avec l'élément suivant de la série jusqu'à trouver une relation périodique dans la série. L'étape 2041 consiste à vérifier qu'une période fondamentale a bien été identifiée, si tel est le cas le résultat 24 est soumis au facteur de correction 25 pour livrer la période mesurée 26, sinon le seuil utilisé à l'étape 2031 est comparée à la moitié de la valeur du seuil initial, lors de l'étape 2034 puis décrémenté d'une valeur prédéfinie, par exemple 10, à l'étape 2035 pour déterminer le nouveau seuil à utiliser lors d'une nouvelle itération du processus d'extraction de la fréquence fondamentale 203, qui va ainsi répéter toutes les étapes précédentes à partir de la 2031 avec le nouveau seuil. Dans le cas où le seuil devrait être inférieur à la moitié du seuil initial après l'étape 2034, le processus d'identification de la fréquence fondamentale 203 est terminé à l'étape 206, et aucune fréquence n'a été identifiée. Le processus d'extraction de la fréquence fondamentale 203 est donc en échec à l'étape 206.The identification step 204 of the fundamental period of the electroacoustic signal 10 is then determined by searching for a periodic relation between the elements of the series 234. The process starts from the smallest element of the series and then searches for multiples of this element while traversing the series in ascending order. Each element of the series is divided by increasing whole numbers until approaching the smallest element. As soon as an element of the series approaches a multiple of this smallest element, then this element is considered to be the fundamental period of the signal; if on the other hand no multiple is found the process is reiterated with the next element of the series until finding a periodic relation in the series. Step 2041 is to verify that a fundamental period has been identified, if so the result 24 is subject to the correction factor 25 to deliver the measured period 26, otherwise the threshold used in step 2031 is compared at half the value of the initial threshold, during step 2034 and then decremented by a predefined value, for example 10, at step 2035 to determine the new threshold to be used during a new iteration of the process of extraction of the fundamental frequency 203, which will thus repeat all the previous steps from 2031 with the new threshold. In the case where the threshold should be less than half the initial threshold after step 2034, the process of identifying the fundamental frequency 203 is completed in step 206, and no frequency has been identified. The process of extracting the fundamental frequency 203 is therefore failing at step 206.

Une fois que la période identifiée 24 du signal est délivrée par le processus 203, puis la correction effectuée par multiplication avec le facteur de correction 25 (comme illustré sur la figure 2 à l'aide du symbole multiplicatif encerclé, désignant cette étape de multiplication), la période mesurée 26 est comparée, à l'étape 207, à des valeurs de périodes correspondant à des notes musicales, qui sont sauvegardées dans la mémoire 109. Cette table 21 de valeurs de notes musicales permet de déterminer, par comparaison, la note la plus proche 11 de manière discrète. Selon une variante préférentielle, l'affichage des résultats d'analyse de la fréquence du signal acoustique se fait au moins partiellement de manière discrète, puisque le résultat affiché doit correspondre à une des périodes sauvegardées dans la table des périodes 21 correspondant à des notes musicales. Il est toutefois possible également selon l'invention d'afficher la fréquence intrinsèque 19 dudit signal électroacoustique reçu 10 de manière continue, par exemple par l'aiguille des minutes 2 en regard d'une échelle de notes 6, comme on le verra sur la base du mode de réalisation illustré par la figure 5.Once the identified period 24 of the signal is delivered by the process 203, then the correction performed by multiplication with the correction factor 25 (as shown in FIG. figure 2 with the help of the circled multiplication symbol, designating this multiplication step), the measured period 26 is compared, at the step 207, with values of periods corresponding to musical notes, which are saved in the memory 109. This table 21 values of musical notes makes it possible to determine, by comparison, the nearest note 11 in a discrete manner. According to a preferred variant, the display of the analysis results of the frequency of the acoustic signal is done at least partially in a discrete manner, since the displayed result must correspond to one of the periods saved in the table of the periods corresponding to musical notes . However, it is also possible according to the invention to display the intrinsic frequency 19 of said electroacoustic signal received continuously, for example by the minute hand 2 opposite a scale of notes 6, as will be seen on the basis of the embodiment illustrated by the figure 5 .

Une fois la note la plus proche 11 identifiée, il reste encore à déterminer la justesse de la période identifiée par rapport à cette note. Cette étape 205 consiste à déterminer l'écart fréquentiel 12 relatif entre la note 11 et le signal reçu 10, que l'on peut de préférence calculer comme suit:

  • Si la fréquence du signal acoustique est inférieure à celle de la note 11 la plus proche, l'écart fréquentiel 12 est égal à la fréquence de la note 11, moins la fréquence correspondant à la période mesurée 26, c'est-à-dire son inverse (la fréquence étant égale, par définition, à l'inverse d'une période), le tout divisé par l'écart fréquentiel entre la note 11 et sa note immédiatement inférieure, c'est-à-dire dans la gamme tempérée d'un demi-ton inférieur. Le tout est ensuite multiplié par 100 pour obtenir un pourcentage. Pour des raisons de simplification et de lisibilité du schéma de la figure 2, la fréquence intrinsèque du signal 19, égale donc à l'inverse de la période mesurée 26, n'y a pas été illustrée.
  • Le même raisonnement s'applique lorsque la fréquence du signal acoustique est supérieure à celle de la note 11 la plus proche, auquel cas l'écart fréquentiel 12 se mesure comme la différence entre celle du signal acoustique et la note la plus proche, le tout divisé par la différence entre la fréquence de la note immédiatement supérieure, c'est-à-dire dans la gamme tempérée d'un demi-ton supérieur, et de la note 11 la plus proche.
Once the closest note 11 has been identified, the correctness of the period identified in relation to this note remains to be determined. This step 205 consists in determining the relative frequency difference 12 between the note 11 and the received signal 10, which can preferably be calculated as follows:
  • If the frequency of the acoustic signal is lower than that of the nearest note 11, the frequency difference 12 is equal to the frequency of the note 11, minus the frequency corresponding to the measured period 26, that is to say its inverse (the frequency being, by definition, the inverse of a period), all divided by the frequency difference between the note 11 and its note immediately below, that is to say in the temperate range of a lower semitone. The whole thing is then multiplied by 100 to get a percentage. For reasons for simplification and legibility of the scheme of the figure 2 , the intrinsic frequency of the signal 19, therefore equal to the inverse of the measured period 26, has not been illustrated.
  • The same reasoning applies when the frequency of the acoustic signal is higher than that of the nearest note 11, in which case the frequency difference 12 is measured as the difference between that of the acoustic signal and the nearest note, the whole divided by the difference between the frequency of the next higher note, that is, the temperate range of a higher semitone, and the nearest note 11.

Selon ce calcul de la justesse de la note pour la gamme tempérée, l'homme du métier pourra constater que la précision est indiquée par rapport à l'écart fréquentiel d'un demi-ton, puisque l'écart entre les différentes notes identifiables est toujours d'un demi-ton. Elle s'étend par conséquent du quart de ton inférieur au quart de ton supérieure. Cette précision est de préférence indiquée par un pourcentage compris entre -50 et +50%.According to this calculation of the accuracy of the score for the tempered range, the skilled person will be able to note that the precision is indicated with respect to the frequency difference of one semitone, since the difference between the different identifiable notes is always a semitone. It therefore extends from a quarter of a tone lower than a quarter of a tone higher. This accuracy is preferably indicated by a percentage between -50 and + 50%.

La figure 3 illustre un mode de réalisation préférentiel d'une pièce d'horlogerie 1 selon l'invention, pourvue de moyens uniquement analogiques pour l'affichage d'informations sur le signal électroacoustique 10 reçu par le microphone de l'accordeur chromatique intégré. La pièce d'horlogerie est ici une montre bracelet pourvue d'une aiguille des minutes 2 et des heures 3, qui constituent les moyens d'affichage analogiques 111 mentionnés précédemment et illustrés sur la figure 1. La montre est également pourvue d'une lunette 5 et d'un cadran 4, en bordure duquel se trouve une échelle des notes 6, constituée par les notes Ab, A, Bb, B,C,Db,D,Eb,E,F,Gb et G qui constituent les 12 notes de la gamme tempérée, une pour chaque demi-ton. Le mode d'affichage choisi selon cette variante est choisi en bémol, il est toutefois possible également d'envisager l'affichage de toutes les notes en mode dièse (#), auquel cas l'échelle 6 se lirait G#, A, A#, B, C, C#, D, D#, E, F, F#, G. On pourra constater que l'échelle des notes 6 comprend un indicateur vierge 61, qui indique qu'aucune note n'a pu être identifiée. Cet indicateur 61 sera ainsi utilisé lorsque l'étape 206, illustrée à la figure 2, aura été effectuée; il peut par ailleurs se trouver sur un endroit du cadran 4, ou de la lunette 5, indépendant de celui utilisé pour l'échelle des notes 6.The figure 3 illustrates a preferred embodiment of a timepiece 1 according to the invention, provided with only analog means for displaying information on the electroacoustic signal 10 received by the microphone of the integrated chromatic tuner. The timepiece is here a wristwatch provided with a minute hand 2 and hours 3, which constitute the analog display means 111 mentioned above and illustrated on the figure 1 . The watch is also provided with a bezel 5 and a dial 4, at the edge of which is a scale of notes 6, consisting of the notes Ab, A, Bb, B, C, Db, D, Eb, E, F, Gb and G which make up the 12 notes of the temperate scale, one for each semitone. The display mode chosen according to this variant is chosen in flat, it is possible however also to consider the display of all the notes in hash (#), in which case the scale 6 would read G #, A, A #, B, C, C #, D, D #, E, F, F #, G. It can be seen that the scale of the notes 6 includes a blank flag 61, which indicates that no notes could be identified. This indicator 61 will thus be used when step 206, illustrated in FIG. figure 2 , will have been done; it can also be on a position of the dial 4, or the telescope 5, independent of the one used for the scale of the notes 6.

Selon le mode de réalisation illustré par la figure 3, on peut constater que l'échelle des notes 6 est disposée en regard de l'aiguille des minutes 2, en périphérie du cadran 4, sur le demi-cadran inférieur correspondant aux heures 3 à 9. Le fait d'utiliser la plus grande des aiguilles 2 pour déterminer la note la plus proche 11 permet une lecture rapide et intuitive du résultat, tandis que l'aiguille des heures 3 est ici utilisée pour donner l'écart fréquentiel 12 entre la note et le signal électroacoustique 10 reçu. Le dispositif d'affichage comprend un indicateur de la justesse des notes 7, constitué ici par des graduations en regard desquelles l'aiguille des heures 3 est positionnée dans le mode accordage de la montre. L'indicateur permet de visualiser une tonalité allant du quart de ton inférieur au quart de ton supérieur à la note la plus proche 11, et permet également une lecture intuitive de cette justesse grâce à la correspondance de la taille de l'aiguille des heures 3 qui bouge en regard des graduations, qui s'étendent de préférence dans le demi-cadran supérieur de la montre, de neuf heures à trois heures, afin de ne pas superposer d'informations par rapport à celles données sur la hauteur de la note. Les informations sur la hauteur de la note la plus proche 11 et la justesse de la note sont ainsi totalement disjoints.According to the embodiment illustrated by the figure 3 it can be seen that the scale of the notes 6 is arranged opposite the minute hand 2, at the periphery of the dial 4, on the lower half-dial corresponding to the hours 3 to 9. The fact of using the largest needles 2 to determine the closest note 11 allows a quick and intuitive reading of the result, while the hour hand 3 is used here to give the frequency differential 12 between the note and the received electroacoustic signal. The display device comprises an indicator of the correctness of the notes 7, constituted here by the graduations opposite which the hour hand 3 is positioned in the tuning mode of the watch. The indicator makes it possible to display a tone ranging from a quarter-tone lower to a quarter-tone higher than the nearest note 11, and also allows an intuitive reading of this accuracy by matching the size of the hour hand. which moves next to the graduations, which extend preferably in the upper half-dial of the watch, from nine o'clock to three o'clock, so as not to superpose information with respect to those given on the height of the note. Information on the pitch of the nearest note 11 and the accuracy of the note are thus totally disjoint.

On pourra constater que l'indication de la justesse par l'aiguille des heures se fait de préférence sur un arc de cercle dont la valeur angulaire est de préférence légèrement inférieure à 180 degrés, de préférence aux alentours de 120 degrés comme illustré sur la figure 3. Par ailleurs, les valeurs des pourcentages d'écart maximaux à plus ou moins 50% sont indiquées à l'intérieur de l'arc de cercle formé par les graduations qui forment l'indicateur 7. Il est également possible de réaliser l'indicateur 7 sous forme d'une échelle de couleurs variant autour du vert correspondant à une note juste, et dont les bords sont rouges pour indiquer que la sonorité est fausse. Il est possible également de réaliser cet indicateur graduel de couleur sous forme d'un arc de cercle dont une extrémité est fine, et l'autre épaisse, à la manière d'un sourcil. L'extrémité pointue correspondrait dans ce cas de préférence à une note trop basse, et l'extrémité épaisse du sourcil correspondrait à une note trop aigüe.It can be seen that the indication of the accuracy by the hour hand is preferably done on an arc whose angular value is preferably slightly less than 180 degrees, preferably around 120 degrees as illustrated in FIG. figure 3 . Moreover, the values of the percentages of maximum deviation at plus or minus 50% are indicated inside the arc of circle formed by the graduations which form the indicator 7. It is also possible to realize the indicator 7 in the form of a color scale varying around the green corresponding to a right note, and whose edges are red to indicate that the sound is false. It is also possible to realize this gradual indicator of color in the form of a circular arc whose one end is fine, and the other thick, in the manner of an eyebrow. In this case, the pointed end would correspond to a note too low, and the thick end of the eyebrow would correspond to a note too acute.

Afin de faciliter encore la lecture de la justesse de la note, le mode de réalisation de la figure 3 illustre de plus une zone cible 8 par rapport à la fréquence de la note 11 la plus proche. Cette zone cible 8, indiquée par exemple par une graduation très épaisse d'une couleur différente, par exemple verte pour indiquer intuitivement la justesse, est de préférence centrée par rapport au cadran 4 et indique que la fréquence du signal acoustique se trouve dans une plage de valeurs suffisamment proche de la note désirée, par exemple moins de 3%, pour ne plus justifier d'un accord supplémentaire. Cette zone cible se trouve de préférence au milieu des graduations de l'indicateur 7 de justesse de la note, mais pourrait aussi se trouver en dehors de l'arc de cercle formé par les graduations.In order to make it even easier to read the correctness of the note, the embodiment of the figure 3 further illustrates a target zone 8 with respect to the frequency of the nearest note 11. This target zone 8, indicated for example by a very thick graduation of a different color, for example green to indicate intuitively the accuracy, is preferably centered with respect to the dial 4 and indicates that the frequency of the acoustic signal is in a range values sufficiently close to the desired note, for example less than 3%, to no longer justify an additional agreement. This target zone is preferably in the middle of the graduations of the indicator 7 of the accuracy of the note, but could also be outside the arc formed by the graduations.

Le mode de réalisation de la figure 3 montre par ailleurs trois boutons poussoirs: le premier 16 étant utilisé pour incrémenter des valeurs et le deuxième pour décrémenter des valeurs, comme par exemple des valeurs de calibrage 14, comme on le verra plus en détail à l'aide de la figure 6. Le dernier bouton poussoir 18 illustré sur la figure 3 est de préférence utilisé pour le changement de mode, notamment pour l'entrée dans le mode accordage qui peut par exemple être activé par une pression prolongée de plus de deux secondes, afin d'éviter tout déclenchement intempestif du mode de calibrage, d'une part parce qu'il utilise les aiguilles et donc ne permet pas de visualiser l'heure simultanément, et d'autre part parce que ce mode est gourmant en énergie car on doit y alimenter le microphone et le microcontrôleur 103 doit y effectuer de nombreux calculs mettant fortement à contribution son horloge de base ou unité centrale (CPU) 104. Ce bouton peut par ailleurs être utilisé de préférence pour valider des réglages, comme par exemple les valeurs retenues pour la calibration. On pourra imaginer que l'entrée dans le mode accordage pourra être validée par le positionnement des deux aiguilles des minutes et des heures, de manière superposée, à midi sur le cadran 4 de la montre.The embodiment of the figure 3 also shows three push buttons: the first 16 being used to increment values and the second to decrement values, such as for example calibration values 14, as will be seen in more detail using the figure 6 . The last push button 18 shown on the figure 3 is preferably used for the change of mode, in particular for entering the tuning mode which can for example be activated by a prolonged pressure of more than two seconds, in order to avoid any untimely tripping of the calibration mode, of a part because it uses the needles and therefore does not allow to view the time simultaneously, and secondly because this mode is energy-hungry because it must feed the microphone and the microcontroller 103 must perform many calculations It makes a lot of use of its basic clock or central processing unit (CPU) 104. This button can also be used preferably to validate settings, such as the values used for calibration. We can imagine that the entry in the tuning mode can be validated by the positioning of the two hands minutes and hours, superimposed at noon on the dial 4 of the watch.

La figure 4 illustre un cadran d'une pièce d'horlogerie 1 selon un exemple illustratif ne faisant pas partie de l'invention, par exemple une montre bracelet, qui est pourvue de moyens d'affichage hybrides, c'est-à-dire à la fois numériques et analogiques. Selon cet exemple, les moyens d'affichage analogiques 111 sont toujours constitués par les aiguilles des heures 2 et des minutes 3, mais cette fois-ci ces moyens analogiques 111 ne sont plus utilisés que pour indiquer la justesse des notes, c'est-à-dire l'écart fréquentiel 12 par rapport à la note la plus proche, tandis que la hauteur de la note la plus proche 11 est affichée numériquement sur un écran LCD, qui constitue les moyens d'affichage numérique 116. Ces moyens d'affichage numérique 116 indiquent, selon la figure 4, que la note Eb a été identifiée; les aiguilles 2 et 3 sont superposées et pointent sur la valeur -44% des graduations d'un indicateur 7 situé dans la demi-partie supérieure du cadran 4. Une zone cible 8 est située au milieu des graduations de l'indicateur, similairement à au mode de réalisation analogique de la figure 3. Les moyens d'affichage numérique 116 permettent d'afficher l'information de justesse de manière redondante, ici sur la gauche de la note 11 indiquée. L'écran LCD se substitue ainsi non seulement à l'échelle des notes 6 de la variante totalement analogique précédemment décrite, mais permet par ailleurs d'indiquer simultanément des informations supplémentaires, voire redondantes, sur le signal électroacoustique 10 reçu par le capteur de signal 101.The figure 4 illustrates a dial of a timepiece 1 according to an illustrative example not forming part of the invention, for example a wristwatch, which is provided with hybrid display means, that is to say at once digital and analog. According to this example, the analog display means 111 are always constituted by the hands of hours 2 and minutes 3, but this time these analog means 111 are only used to indicate the accuracy of the notes, that is, ie the frequency difference 12 relative to the nearest note, while the height of the nearest note 11 is displayed digitally on an LCD screen, which constitutes the digital display means 116. These means of digital display 116 indicate, according to the figure 4 , that the note Eb has been identified; the needles 2 and 3 are superimposed and point to the value -44% of the graduations of an indicator 7 located in the upper half of the dial 4. A target zone 8 is located in the middle of the graduations of the indicator, similarly to to the analog embodiment of the figure 3 . The digital display means 116 make it possible to display the accuracy information redundantly, here on the left of the note 11 indicated. The LCD screen thus replaces not only the scale of the notes 6 of the totally analog variant described above, but also makes it possible to simultaneously indicate additional or even redundant information on the electroacoustic signal received by the signal sensor. 101.

Selon une variante non représentée, l'information supplémentaire indiquée par les moyens d'affichage numérique 116 pourrait être le pitch, c'est à dire la fréquence de référence utilisée pour la mesure fréquentielle des notes, lorsque celle-ci peut être réglée sur une fréquence autre que la fréquence usuelle du LA à 440Hz. De préférence, ces moyens se situent dans la partie basse du cadran 4 et en dessous des aiguilles 2 et 3 lorsqu'elles sont utilisées en mode accordage pour indiquer la justesse de la note 11 la plus proche.According to a variant not shown, the additional information indicated by the digital display means 116 could be the pitch, that is to say the reference frequency used for the frequency measurement of the notes, when this can be set on a frequency other than the usual LA frequency at 440Hz. Preferably, these means are located in the lower part of the dial 4 and below the needles 2 and 3 when used in tuning mode to indicate the accuracy of the note 11 closest.

La figure 5 illustre un mode de réalisation similaire à celui de la figure 3, c'est-à-dire selon lequel l'affichage est totalement analogique, effectué par les moyens 111 constitués par l'aiguille des minutes 2 et des heures 3. Selon ce mode de réalisation toutefois, la fréquence intrinsèque 19 du signal acoustique est affichée de manière continue par l'aiguille des minutes 2, en regard d'une échelle des notes, sans qu'une comparaison ait été effectuée lors du processus d'identification de la note 20 pour déterminer la note la plus proche 11. Ainsi, cette aiguille 2 peut pointer sur n'importe quelle valeur et pas seulement les valeurs discrètes des notes indiquées sur l'échelle 6 en bordure du cadran. Selon cette variante, l'aiguille des minutes 3 consiste en quelle sorte en un « zoom » de celle des minutes 2, pour laquelle aucune valeur discrète n'a été identifiée. La lecture est ainsi plus intuitive, d'une part, puisque l'aiguille des minutes contient déjà intrinsèquement une information de justesse, en plus de l'information sur la note 11 la plus proche, et d'autre part elle permet d'économiser des étapes de traitement dans le processus d'identification de la note, puisque la discrétisation de la valeur n'est plus nécessaire. Comme pour la variante de la figure 3, les indicateurs 7, zone cible 8, échelle des notes sont situés de manière identique sur le cadran; il serait toutefois possible d'inverser la position des graduations 7 et de l'échelle des notes, ou encore d'utiliser une plus grande portion angulaire du cadran, par exemple 270 degrés ou plus, voire la totalité du cadran pour répartir l'échelle des notes 6 afin de mieux lire directement la première information intrinsèque sur la valeur de la fréquence du signal 10, grâce à la plus grande portion angulaire disponible pour l'affichage de chaque demi-ton. Les différents boutons 16,17, et 18 et leur fonction ne sont pas décrits pour cette figure car ils sont en tous points identiques à ceux illustrés par la figure 3.The figure 5 illustrates an embodiment similar to that of the figure 3 that is to say, in which the display is totally analog, performed by the means 111 constituted by the minute hand 2 and hours 3. According to this embodiment, however, the intrinsic frequency 19 of the acoustic signal is continuously displayed by the minute hand 2, next to a scale of the notes, without a comparison being made during the identification process of the note 20 to determine the closest note 11. Thus, this needle 2 can point to any value and not only the discrete values of the notes indicated on the scale 6 at the edge of the dial. According to this variant, the minute hand 3 consists of what sort of a "zoom" of that of minutes 2, for which no discrete value has been identified. The reading is thus more intuitive, on the one hand, since the minute hand already contains intrinsically accurate information, in addition to the information on the note 11 closest, and secondly it saves processing steps in the process of identifying the note, since the discretization of the value is no longer necessary. As for the variant of figure 3 , indicators 7, target zone 8, scale notes are located identically on the dial; it would however be possible to invert the position of the graduations 7 and the scale of the notes, or to use a larger angular portion of the dial, for example 270 degrees or more, or even the entire dial to spread the scale notes 6 to better directly read the first intrinsic information on the value of the frequency of the signal 10, thanks to the largest angular portion available for the display of each semitone. The various buttons 16, 17, and 18 and their function are not described for this figure because they are in all respects identical to those illustrated by the figure 3 .

Une variante, ne faisant pas partie de l'invention, plus sommaire pour l'affichage de la fréquence intrinsèque 19 du signal 10 pourrait par ailleurs prévoir que les deux aiguilles des heures 3 et des minutes 2 sont superposées lors de l'affichage de la fréquence détectée et pointent toutes deux sur une valeur lue sur l'échelle des notes 6. Cette variante requiert toutefois que la justesse doit être appréciée par l'utilisateur sans l'aide d'aucun autre indicateur 7.A variant, not part of the invention, more summary for the display of the intrinsic frequency 19 of the signal 10 could moreover provide that the two hands of the hours 3 and minutes 2 are superimposed during the display of the frequency detected and both point to a value read from the scale of notes 6. However, this variant requires that the accuracy must be appreciated by the user without the aid of any other indicator 7.

La figure 6 illustre, en tant que exemple ne faisant pas partie de l'invention, un accordeur chromatique intégré à une montre selon lequel la position angulaire des notes 11 sur l'échelle des notes 6, cette fois-ci disposée sur la lunette 5 et non pas sur le cadran, coïncide avec celle des heures. La répartition angulaire est de 360 degrés pour toutes les notes, soit 30 degré par demi-ton. Ainsi cette variante peut être utilisée tant dans le cadre de l'affichage de la note la plus proche 11, conformément aux modes de réalisation illustrés par les figures 1 à 4, mais aussi avantageusement dans le cadre de la méthode d'affichage continu de la figure 5, grâce à l'espace angulaire agrandi pour chaque demi-ton. Par ailleurs, l'affichage coïncidant entre les notes de l'échelle des notes et celle des heures permet de substituer l'information des heures par des notes, sans perdre pour autant le caractère intuitif de lecture en mode normal, tandis que le mode accordage ne requiert aucune information supplémentaire devant être placée ailleurs sur le cadran. Selon cette solution, on pourra remarquer que les boutons ont été remplacés par une couronne 9 afin d'effectuer les réglages et les changements de mode.The figure 6 illustrates, as an example not forming part of the invention, a chromatic tuner integrated with a watch according to which the angular position of the notes 11 on the scale of the notes 6, this time arranged on the telescope 5 and not on the dial, coincides with that of hours. The angular distribution is 360 degrees for all notes, or 30 degrees per semitone. Thus this variant can be used both in the context of the display of the closest note 11, in accordance with the embodiments illustrated by the Figures 1 to 4 , but also advantageously as part of the continuous display method of the figure 5 , thanks to the enlarged angular space for each semitone. Moreover, the display coinciding between the notes of the scale of the notes and that of the hours makes it possible to substitute the information of the hours by notes, without losing however the intuitive character of reading in normal mode, while the tuning mode does not require any additional information to be placed elsewhere on the dial. According to this solution, it will be noted that the buttons have been replaced by a ring 9 in order to make adjustments and changes of mode.

Une différence importante entre l'exemple de la figure 6 avec les autres modes illustrés consiste en le fait que l'aiguille des minutes 2, qui peut du reste être superposée à celle des heures 3, permet de visualiser une valeur de calibrage 14, qui peut s'étendre de préférence entre 435 et 445 Hz, par exemple en fonction des préférences de l'utilisateur selon le contexte acoustique et les effets sonores voulus. La fréquence de référence 13 est calibrée par défaut à 440 Hz, qui constitue sa valeur nominale, et peut être de préférence être ajustée à la baisse ou à la hausse par pas de 1 Hz. On peut toutefois également prévoir que la couronne 9 permet un réglage continu des valeurs de calibrage 14. Ces manipulations sur les valeurs de calibrage 14 ont un impact sur le calcul des fréquences intrinsèques 19 du signal électroacoustique 10.An important difference between the example of the figure 6 with the other illustrated modes consists in the fact that the minute hand 2, which can be superimposed on that of the hours 3, makes it possible to display a calibration value 14, which can preferably range between 435 and 445 Hz , for example according to the preferences of the user according to the acoustic context and the desired sound effects. The reference frequency 13 is calibrated by default at 440 Hz, which constitutes its value nominal, and can preferably be adjusted downward or upward in steps of 1 Hz. However, it is also possible that the ring 9 allows a continuous adjustment of the calibration values 14. These manipulations on the calibration values 14 have an impact on the calculation of the intrinsic frequencies 19 of the electroacoustic signal 10.

La valeur de calibrage est affichée sur une échelle de valeurs de calibrage 15, disposée en regard d'une des aiguilles 2 ou 3, de préférence l'aiguille des minutes 2, de préférence sur la moitié inférieure du cadran, afin de laisser de la place disponible pour un indicateur 7 de justesse des notes, similairement aux variantes précédentes décrites.The calibration value is displayed on a scale of calibration values 15 placed opposite one of the needles 2 or 3, preferably the minute hand 2, preferably on the lower half of the dial, in order to leave the space available for an indicator 7 of the accuracy of the notes, similar to the previous variants described.

Bien que l'exemple de la figure 6 utilise une couronne 9 pour régler la valeur de calibrage 4, il est possible d'envisager utiliser des boutons poussoirs 16 et 17, comme sur la figure 3, afin d'incrémenter et décrémenter les valeurs de calibrage 14.Although the example of the figure 6 uses a ring 9 to set the calibration value 4, it is possible to consider using push buttons 16 and 17, as on the figure 3 , in order to increment and decrement the calibration values 14.

Lesfigures 7a à 7d illustrent d'autres possibilités de mode d'affichage, qui ont toutes en commun de disposer l'échelle des notes sur la lunette 5 d'une montre, ainsi que d'utiliser une couronne 9. Par ailleurs, toutes ces solutions utilisent l'aiguille des minutes 2, et non l'aiguille des heures contrairement aux variantes précédemment décrites, pour l'affichage de la justesse des notes. L'aiguille des minutes 2 indique l'écart fréquentiel 12 en regard d'un indicateur 7 constitué par des graduations sur un arc de cercle sur la demi-partie supérieure du cadran, de préférence centré à midi et s'étendant sur un angle compris de préférence entre 120 et 180 degrés.Figures 7a to 7d illustrate other display mode possibilities, all of which have in common to arrange the scale of the notes on the bezel 5 of a watch, as well as to use a crown 9. Moreover, all these solutions use the minute hand 2, not the hour hand contrary to the previously described variants, for displaying the accuracy of the notes. The minute hand 2 indicates the frequency difference 12 opposite an indicator 7 constituted by graduations on an arc of circle on the upper half of the dial, preferably centered at noon and extending on an angle included preferably between 120 and 180 degrees.

L'exemple illustratif de la figure 7a reprend la même échelle des notes 6 que celle illustrée par la figure 6, représentant les notes en mode mixte bémol/dièse sur l'intégralité du pourtour de la lunette 5. Il s'agit d'un mode d'affichage totalement analogique, conformément au mode de réalisation de la figure 3. Similairement la figure 7b concerne également un exemple illustratif selon lequel l'affichage est totalement analogique, les aiguilles des minutes 2 et des heures ayant les même fonctions que pour la figure 7a, mais le mode d'affichage des notes sur l'échelle des notes 6 est simplement dual par rapport au dièse et au bémol, c'est à dire que toutes les notes sont affichées, lorsqu'un choix est possible, à la fois en tant que dièse de la note inférieure ou bémol de la note supérieure.The illustrative example of the figure 7a resumes the same scale of notes 6 as illustrated by the figure 6 , representing the notes in mixed mode flat / sharp on the entire circumference of the telescope 5. This is a completely analog display mode, in accordance with the embodiment of the figure 3 . Similarly, figure 7b also relates to an illustrative example according to which the display is totally analog, the hands of minutes 2 and hours having the same functions as for the figure 7a but the way notes are displayed on the 6 note scale is simply dual compared to sharp and flat, ie all notes are displayed, when a choice is possible, both as a sharp of the lower note or flat of the upper note.

La figure 7c concerne un exmple illustratif d'un mode d'affichage hybride ne faisant pas partie de l'invention, qui utilise un affichage numérique pour les notes les plus proches 11 du signal acoustique; la lunette 5 peut ainsi comporter à nouveau les chiffres des heures en lieu des places des notes des variantes des figures 7a et 7b. Les moyens d'affichage numérique 116 sont de préférence un écran LCD situé sur la partie inférieure du cadran.The Figure 7c an exemplary example of a hybrid display mode not forming part of the invention, which uses a digital display for the closest notes 11 of the acoustic signal; the telescope 5 can thus again include the hour digits instead of the places of the notes of the variants of the Figures 7a and 7b . The digital display means 116 are preferably an LCD screen located on the lower part of the dial.

La figure 7d concerne à nouveau un mode de réalisation à affichage analogique selon l'invention, dont la différence avec les solutions des figures 7a et 7b concerne la disposition des notes sur la lunette, l'échelle des notes 6 étant située sur la partie inférieure de la lunette 5, entre 3 heures pour la note Ab (A bémol) et 8h30 pour la note G. L'échelle des notes 6 n'est ainsi pas centrée étant donné que les douze demi-tons associés aux notes se suivent sans qu'aucune indication ne soit prévue si aucune fréquence ne peut être déterminée lors du processus d'identification de la note 20.The figure 7d again relates to an embodiment with an analogue display according to the invention, the difference with the solutions of the Figures 7a and 7b the arrangement of the notes on the telescope, the scale of the notes 6 being located on the lower part of the telescope 5, between 3 hours for the note Ab (A flat) and 8:30 for the note G. The scale of the notes 6 is thus not centered since the twelve semitones associated with the notes follow one another without any indication being provided if no frequency can be determined during the identification process of the note.

La figure 8 illustre un exemple illustratif qui permet d'afficher la justesse de la note en utilisant la lecture de la position relative des aiguilles des heures 3 par rapport à celle des minutes 2, dispensant ainsi d'un indicateur 7 de justesse dédié. Selon cet exemple, la note la plus proche 11 est affichée par l'aiguille des minutes 2 qui pointe sur une note de l'échelle des notes 6, répartie ici sur l'ensemble du secteur angulaire de la lunette 5. La justesse de la note est ensuite affichée par l'aiguille des heures 3, qui se positionne dans un secteur angulaire d'une amplitude de 30 degrés autour de l'aiguille des minutes 2. La déviance maximale pour l'aiguille des heures 3 est de 15 degrés de part et d'autre de celle des minutes 2 ; cette déviance correspond en effet selon cette variante à un quart de ton, puisque chaque demi-ton occupe un espace angulaire de 30 degrés. La justesse d'une note est ainsi confirmée par la superposition des deux aiguilles 2,3 sur l'une des notes de l'échelle 6, ici sur le LA à une heure sur le cadran 4.The figure 8 illustrates an illustrative example that displays the accuracy of the note using the reading of the relative position of the hours of hands 3 relative to that of minutes 2, thus dispensing with a dedicated accuracy indicator 7. According to this example, the closest note 11 is displayed by the minute hand 2 which points to a note of the scale of the notes 6, distributed here over the whole of the angular sector of the telescope 5. The accuracy of the note is then displayed by the hour hand 3, which is positioned in an angular sector of an amplitude of 30 degrees around the minute hand 2. The maximum deviance for the hour hand 3 is 15 degrees of on both sides of minutes 2; this deviation corresponds in effect according to this variant to a quarter of a tone, since each semitone occupies an angular space of 30 degrees. The accuracy of a note is thus confirmed by the superposition of the two hands 2,3 on one of the notes of the scale 6, here on the LA at one o'clock on the dial 4.

Etant donné l'espace angulaire réduit pour indiquer la justesse de la note, on pourra utiliser des formes particulières ou des couleurs particulières, par exemple vert pour les aiguilles affichant la note et celle indiquant la justesse, indifféremment du fait qu'il s'agisse de celles des heures 3 ou des minutes 2 (la fonction de chacune pouvant être inversée), et les superposer de telle sorte que la couleur indiquant la justesse, par exemple du rouge, soit cachée par celle, par exemple du vert, indiquant la note lorsque les fréquences concordent. En ce qui concerne la forme, on pourra privilégier par exemple une aiguille creuse, de préférence l'aiguille des minutes 2, plus grande que celle des heures 3, l'aiguille des heures 3 venant alors se loger dans la creusure 71 de l'aiguille des minutes 2 lorsque les fréquences concordent. Cet exemple illustratif présente l'avantage de ne pas charger le cadran 4 par des informations sur la justesse, libérant ainsi de la place pour d'autres types d'informations; il présente toutefois l'inconvénient d'un coût plus élevé d'usinage de l'aiguille creuse, qui est plus difficile à réaliser qu'une aiguille standard.Given the reduced angular space to indicate the accuracy of the note, it will be possible to use particular shapes or particular colors, for example green for the needles displaying the note and the one indicating the accuracy, regardless of whether it concerns those of the hours 3 or minutes 2 (the function of each can be reversed), and superimpose them so that the color indicating the correctness, for example red, is hidden by that, for example green, indicating the note when the frequencies match. Regarding the shape, it may be preferred for example a hollow needle, preferably the minute hand 2, greater than that of the hours 3, the hour hand 3 then being housed in the recess 71 of the minute hand 2 when the frequencies match. This illustrative example has the advantage of not loading the dial 4 with information on correctness, thus freeing up space for other types of information; however, it has the disadvantage of a higher cost of machining the hollow needle, which is more difficult to achieve than a standard needle.

L'exemple de la figure 8 est illustrée avec une couronne 9 pour les changements de mode. On comprendra toutefois que cette solution est tout à fait envisageable avec des boutons poussoirs conformément aux modes de réalisation des figures 3 et 5.The example of figure 8 is illustrated with a crown 9 for mode changes. However, it will be understood that this solution is quite possible with pushbuttons in accordance with the embodiments of FIGS. figures 3 and 5 .

Plus généralement, les différents modes de réalisation décrits ci-dessus sont donnés à titre d'exemple et ne doivent en aucun cas être interprétés de façon limitative. Il est par exemple envisageable de combiner des caractéristiques afférentes aux différents modes de réalisation décrits, ou encore en ajouter d'autres, connues de l'homme du métier, sans sortir du cadre de l'invention tel que défini par les revendications.
