Le dispositif suivant l'invention permet de remédier à cet inconvénient. Il comporte en effet selon une première caractéristique un système mécanique permettant d'allumer un élément électroluminescent à l'aide d'une came pivotant autour de l'axe de l'élément de tension de la dite corde. De bloquer la came dans la position ainsi définie, en la solidarisant à l'axe de tension. L'élément électroluminescent ainsi activé signale au musicien l'état de tension de la corde. Toute variation de tension de la corde implique un mouvement de rotation à la came désactivant le contact alimentant l'élément lumineux. L'extinction de ce signal lumineux indique au The device according to the invention overcomes this drawback. According to a first characteristic, it in fact comprises a mechanical system making it possible to ignite an electroluminescent element by means of a cam pivoting about the axis of the tension element of said rope. To lock the cam in the position thus defined, securing it to the tension axis. The electroluminescent element thus activated signals to the musician the state of tension of the string. Any variation in the tension of the rope implies a rotational movement of the cam, deactivating the contact supplying the light element. The extinction of this light signal indicates to the
musicien le changement de l'état de tension de la dite corde. musician changing the tension state of the said string.
Selon un mode particulier de réalisation: - Un élément de reconnaissance vibratoire est aussi incorporé à l'ensemble de tension des cordes dans le corps. Cet appareil permet grâce à un élément de réglage spécifique la sélection According to a particular embodiment: - A vibration recognition element is also incorporated in the string tension assembly in the body. This device allows, thanks to a specific adjustment element, the selection
de la note correspondant à la corde. of the note corresponding to the string.
Un second élément de réglage spécifique permet la sélection de la fréquence vibratoire émise par la corde. La reconnaissance de la vibration émise par la corde lors de son réglage par l'appareil de reconnaissance vibratoire, déclenche l'allumage d'un second élément électroluminescent, qui indique au musicien l'état de réglage de la corde. Le second élément électroluminescent peut être couplé à un signal sonore temporisé. Le dispositif sonore temporisé s'active lors de la mise sous tension de l'élément électroluminescent. Le dispositif sonore temporisé étant surtout préconisé pour A second specific adjustment element allows the selection of the vibrating frequency emitted by the string. Recognition of the vibration emitted by the string when it is adjusted by the vibratory recognition device, triggers the ignition of a second electroluminescent element, which indicates to the musician the state of adjustment of the string. The second electroluminescent element can be coupled to a timed audible signal. The timed sound device activates when the electroluminescent element is switched on. The timed sound device is especially recommended for
l'utilisation de l'invention par les mal ou non voyants. the use of the invention by the blind or blind.
Le dessin annexé illustre l'invention: La figure A du dessin 1/1 représente le mode d'implantation de la dite invention. Le dessin représente l'implantation de l'invention sur le support de clé d'une guitare. L'invention n'est pas utilisée que dans cette application. Elle peut être adaptée à tous les instruments à cordes utilisant des clés de réglage pour la tension des dites cordes. La figure B du dessin 1/1 représente les différents éléments constitutifs de The appended drawing illustrates the invention: FIG. A of the drawing 1/1 represents the mode of implementation of the said invention. The drawing represents the implementation of the invention on the key holder of a guitar. The invention is not used only in this application. It can be adapted to all stringed instruments using adjustment keys for the tension of said strings. Figure B of the drawing 1/1 represents the various constituent elements of
l'invention.the invention.
En référence à ce dessin, le dispositif comporte un ensemble de tension (Rep.1) figure A dessin 1/1 fixé sur With reference to this drawing, the device comprises a tension assembly (Ref. 1) figure A drawing 1/1 fixed on
l'instrument (Rep.2).the instrument (Rep.2).
En référence à la figure B dessin 1/1, le dispositif ensemble de tension (Rep.1) comporte un compartiment contenant un système permettant la reconnaissance et le réglage des notes à obtenir. Un processeur " appareil de reconnaissance de fréquences vibratoires " (Rep.15) permet la reconnaissance des fréquences vibratoires ainsi que des notes. Ce compartiment comporte un microphone (Rep.13) qui capte les sons émis par la corde (17) de l'instrument (Rep.2). Ce microphone est relié à l'appareil de reconnaissance de fréquences vibratoires (15) équipé d'un mode de sélection de notes (Rep.12) et un mode de sélection de fréquences (Rep.14). L'appareil de reconnaissance de fréquences vibratoires (15) lorsqu'il reconnaît le son émis par la corde (17) suivant la présélection établie, envoie un signal électrique à un élément électroluminescent (11) qui indique au musicien que l'accord est réalisé. Un signal sonore temporisé émis simultanément à l'activation de la diode électroluminescente indique l'obtention du réglage de la corde. En référence au dessin 1/1 (figure B), le dispositif ensemble de tension (Rep.1) comporte une prise (10) permettant lors de l'accord de l'instrument de se brancher sur la sortie amplificateur de celui-ci. Ceci permet au musicien ou à l'accordeur de prendre directement le son sur les micros installés sur l'instrument de musique. Ceci permet un accord de l'instrument même dans un environnement bruyant générateur de sons parasitaires pouvant perturber l'accord de l'instrument. Le dispositif suivant l'invention est constitué d'une clé de réglage (16) munie d'une vis sans fin, transmettant un mouvement de rotation à un axe (Rep.8) perpendiculairement à l'axe de la vis sans fin. L'axe (Rep.8) est associé à un bouton de réglage ayant la forme d'une came à un bossage qui lors de sa rotation est indépendant de la rotation de l'axe perpendiculaire à la vis sans fin (Rep.8). La rotation de ce bouton came (Rep.7) permet à la came d'actionner un contact électrique(Rep.5)commandant l'allumage de la diode électroluminescente (9) indiquant la position de l'accord en Referring to Figure B drawing 1/1, the tensioning device (Rep.1) has a compartment containing a system for recognizing and adjusting the notes to be obtained. A processor "vibration frequency recognition device" (Ref.15) allows the recognition of vibration frequencies as well as notes. This compartment includes a microphone (Rep.13) which picks up the sounds emitted by the string (17) of the instrument (Rep.2). This microphone is connected to the vibratory frequency recognition device (15) equipped with a note selection mode (Rep.12) and a frequency selection mode (Rep.14). The vibratory frequency recognition device (15) when it recognizes the sound emitted by the string (17) according to the preset preset, sends an electrical signal to an electroluminescent element (11) which indicates to the musician that the chord is achieved . A timed acoustic signal emitted simultaneously with the activation of the light-emitting diode indicates that the rope has been adjusted. Referring to drawing 1/1 (Figure B), the tensioning device (Rep.1) has a socket (10) allowing the instrument to be connected to the amplifier's output. This allows the musician or tuner to take sound directly from the microphones installed on the musical instrument. This allows tuning of the instrument even in a noisy environment generating parasitic sounds that can disturb the tuning of the instrument. The device according to the invention consists of an adjustment key (16) provided with an endless screw, transmitting a rotational movement to an axis (Rep.8) perpendicular to the axis of the endless screw. The axis (Rep.8) is associated with an adjustment knob having the shape of a cam with a boss which during its rotation is independent of the rotation of the axis perpendicular to the worm (Rep.8) . The rotation of this cam button (Rep. 7) allows the cam to activate an electrical contact (Rep. 5) controlling the lighting of the light-emitting diode (9) indicating the position of the tuning in
