Abstract

A string is held between a bracket and a tensioner key on a chassis plate. A propeller blade is mounted on a shaft running in bearings in a support fixed to the chassis. A dc motor with a voltage controlled variable speed controller drives the propeller shaft so that the blades strike the string and another string parallel to it and supported on a rigid plate. This is supported by a flexible arm fixed to the chassis. This plate can move between stops. Microphones are located close to the strings to pick-up their sounds as the blades strike the strings. The notes are varied by contacting the strings with the index finger placed on the string adjacent to the bracket.

Description

INSTRUMENTS DE MUSTQUE ELECTRIQUE DE PERCUSSION. ELECTRICAL PERCUSSION INSTRUMENTS.

POLYPHONIQUE. POLYPHONIC.


b) La présente invention concerne les instruments de musique électriques nécessitant l'emploi d'un amplificateur guitare. Bien que ce soit un instrument de per- cussion, sa famille la plus proche est la guitare.
b) The present invention relates to electric musical instruments requiring the use of a guitar amplifier. Although it is a percussion instrument, its closest family is the guitar.

c) Cette invention est entièrement originale, en dehors du système de la corde amplifiée par micro emprunté à la guitare électrique. c) This invention is entirely original, apart from the system of the microphone amplified string borrowed from the electric guitar.

d) L'invention repose sur le principe d'une hélice à deux pales flexibles dont l'une est plus courte que l'autre. d) The invention is based on the principle of a propeller with two flexible blades, one of which is shorter than the other.

L'arbre à hélice est parallèle à une ou plusieurs cordes montées fixes ou sur supports mobiles. Ces cordes sont à une distance minimale supérieure au rayon x' de l'hélice. Lorsqu'on rapproche une corde à une distance plus petite que x' et plus grande que x, la pale du rayon x' entre en contact avec la corde : donc, pour un tour complet de l'hélice, un seul contact. The propeller shaft is parallel to one or more ropes mounted fixed or on movable supports. These strings are at a minimum distance greater than the radius x 'of the propeller. When a rope is brought closer to a distance smaller than x 'and larger than x, the blade of radius x' comes into contact with the rope: therefore, for a complete turn of the propeller, only one contact.

Lorsqu'on rapproche cette même corde à une distance plus petite que x, la pale du rayon x entre en contact avec la corde et pour un tour complet de l'hélice, les deux pales entrent en contact. When this same rope is brought closer to a distance smaller than x, the blade of the x-ray comes into contact with the rope and for a complete turn of the propeller, the two blades come into contact.

Donc, en déplaçant une corde plus ou moins, de manière à ce qu'elle entre en con tact ou non avec la pale du rayon x ou celle du rayon x', on obtient à volonté aucun ou un ou deux contacts avec plus ou moins de fonce (selon le déplacement plus ou moins important que l'on fait faine à la corde pour entrer en contact avec les pales)
La corde est étouffée par de la mousse et du feutre à son extrémité opposée à l'hélice, et sa vibration à chaque contact est captée par un micro (micro à bobinage pour corde en fer). Le son obtenu après amplification est un son de percussion semblable au tabla, darbouka, tome de batterie, etc... suivant la tension de la corde ou sa grosseur.So, by moving a string more or less, so that it comes into contact or not with the blade of the x-ray or that of the x-ray, we obtain at will no or one or two contacts with more or less darkens (depending on the more or less significant displacement that the rope is made to come into contact with the blades)
The rope is smothered by foam and felt at its end opposite the propeller, and its vibration at each contact is picked up by a microphone (winding microphone for iron rope). The sound obtained after amplification is a percussion sound similar to tabla, darbouka, drum tome, etc ... depending on the tension of the string or its size.

e) Le dessin annexé 1/3 est le schéma de l'invention à 2 cordes hélice à 2 pales. Les dessins 2/3 : Fig 1 est le schéma de l'hélice ou de face pour comprendre la différence des rayons ; Fig 2, dessin vue de face d'un percuteur de corde pouvant remplacer l'hélice. Le dessin 3/3 représente les manoeuvres d'utilisation. e) The attached drawing 1/3 is the diagram of the invention with 2 strings, propeller with 2 blades. Drawings 2/3: Fig 1 is the diagram of the propeller or from the front to understand the difference in radii; Fig 2, front view drawing of a rope striker which can replace the propeller. Drawing 3/3 shows the maneuvers of use.

6) Telle qu'elle est représentée l'invention stérophonique est constituée d'un plateau général 4 sur lequel une corde 1 est tendue entre le chevalet 15 et la clé type guitare 10. 6) As shown, the stereo invention consists of a general plate 4 on which a string 1 is stretched between the bridge 15 and the guitar type key 10.

L'hélice 5-6 est montée sur l'arbre 17 reposant sur des coussins ou roulements. The propeller 5-6 is mounted on the shaft 17 resting on cushions or bearings.

Les roulements sont montés fixes sur le support 12 solidaire du plateau 14 ; un moteur 7 à courant continu et à vitesse variable, par variateur, électronique de tension, entraine l'arbre. The bearings are fixedly mounted on the support 12 integral with the plate 14; a variable speed direct current motor 7, by variator, voltage electronics, drives the shaft.

La deuxième corde est montée symétriquement (pour la synchronisation) parallèlement et à une distance minima supérieure à x'. Elle est fixée sur une plaquette rigide 18 et tendue entre le chevalet 15 et la clé type guitare 10. Cette plaquette est reliée au plateau principal 14 par un support flexible qui ne permet que le déplacement vers la vis de butée 4 et son retour sur la vis de butée 3 ; la vis de butée 3 étant réglée, bien sûr à une distance minima supérieure à x' et la vis 4 règlée, elle, en fonction de l'intensité de contact ou percussion désirée avec les pales 5-6.  The second rope is mounted symmetrically (for synchronization) parallel and at a minimum distance greater than x '. It is fixed on a rigid plate 18 and stretched between the bridge 15 and the guitar type key 10. This plate is connected to the main plate 14 by a flexible support which only allows movement towards the stop screw 4 and its return to the stop screw 3; the stop screw 3 being adjusted, of course at a minimum distance greater than x 'and the screw 4 adjusted, for its part, depending on the desired contact or percussion intensity with the blades 5-6.

La manoeuvre de la plaquette 18 peut s'effectuer manuellement directement en appuyant dessus. On peut aussi rapporter une pièce 19 solidaire à la plaquette et décalant le point d'appui vers la corde du bas facilitant la technique du jeu. On peut aussi la déplacer électromagnétiquement avec contact électrique sur le plateau (dans la région 20 - Planche 1/3). The maneuver of the plate 18 can be carried out manually directly by pressing it. It is also possible to bring a piece 19 integral with the plate and shifting the fulcrum towards the bottom string facilitating the technique of the game. It can also be moved electromagnetically with electrical contact on the board (in region 20 - Plate 1 / 3).

La manoeuvre pour établir le contact avec la corde 1 consiste à soulever le corde avec le gras de l'index le plus près possible du chevalet ; on peut varier sa tension avec la main gauche et établin en même temps le contact de la corde 2 avec l'index de cette main gauche en appuyant sur l'emplacement 20 (PL.3/3). The maneuver to establish contact with the string 1 consists in lifting the string with the fat of the index finger as close as possible to the bridge; its tension can be varied with the left hand and at the same time establishing contact of the cord 2 with the index finger of this left hand by pressing on location 20 (PL.3 / 3).

Les micros 8 sont montés au plus près des cordes en fonction du déplacement de celle-ci. Ils sont fixés sur le support 16 et solidaires du plateau par l'intermédiaire des plaques de mousse 11, le tout fixé par collage. Les plaques de mousse permettent d'isoler les micros des vibrations mécaniques du moteur et de sa transmission. The microphones 8 are mounted as close as possible to the strings as a function of the displacement thereof. They are fixed on the support 16 and secured to the plate by means of the foam plates 11, the whole fixed by gluing. The foam plates isolate the microphones from the mechanical vibrations of the engine and its transmission.

Le signal des 2 micros peut être récupéré séparment donc stéréophonique ou mixé en signal monophonique. The signal from the 2 microphones can be recovered separately stereophonically or mixed as a monophonic signal.

9) L'invention prend sa place dans les instruments de musique électrique. Il peut être utilisé dans tout orchestre ou en instrument soliste.  9) The invention takes its place in electric musical instruments. It can be used in any orchestra or as a solo instrument.
