Definitions
- the invention relates to a shutter for facilitating the emission of predetermined notes from a transverse flute or the like.
- a shutter for facilitating the emission of predetermined notes from a transverse flute or the like.
- the object of the invention is to propose a shutter which facilitates the emission of said notes. This object is achieved by the fact that, according to the invention, there is at least one auxiliary resonator in the obturator opening out onto the air column and produced in the form of a chamber whose length is specifically granted to facilitate '' issuance of at least one predetermined note from the instrument.
- the length of the chamber is granted so that its natural frequency is a binary logarithm of the frequency of the fundamental of the predetermined note.
- the specific resonator is tuned to a sensitive harmonic (one of the upper octaves) of the fundamental of the note in question.
- the room is advantageously designed in the form of a room of variable length which is adjusted for tuning.
- This adjustment can be fixed by one means or another depending on the adjustment means if one wishes an immutable agreement; it can be left free if you want to be able to change it later, if only to adapt it to the different tuning forks in use.
- the specific resonator (s) consist of one or more concentric chambers, advantageously of adjustable length.
- the shutter is honeycombed with holes constituting the specific resonators.
- the shutter comprises an internal piston sliding in an adjustable manner in an annular piston, the front end of which has a choice of a planar shape, a convex flared shape, a concave flared shape, a stepped flared shape , a diverging frustoconical form, or a converging frustoconical form.
- Figure 1 shows a transverse flute 12 with its mouth 13 and, to the left of the mouth hole, a cavity traditionally closed by a cork stopper 14 clamped between two metal plates 15 mounted on a threaded rod 16 whose end 17 screws into a knurled button 18.
- the cork stopper 14 To be waterproof, the cork stopper 14 must be forced into this conical part of the mouth.
- the coefficient of friction of the plug 14 being greater than the torque delivered by the knurled button 18, the system does not work in the direction of elongation of the cavity (action of screwing the button). The system does not work in the other direction either (unscrewing action), because in this case the button is released without modifying in any way the volume of the cavity in question.
- the invention proposes to replace this fixed plug with a system of one or more specific resonators.
- the conventional plug is replaced by a plug made up of one or more concentric pistons sliding in one another and thus forming concentric chambers of adjustable length.
- a plug made up of one or more concentric pistons sliding in one another and thus forming concentric chambers of adjustable length.
- a surface 25 with two or more sides makes it possible to rotate the assembly to adjust the position thereof while a vernier of the “Palmer” type produced on this surface pinpoint its position.
- the central piston 20 slides in the annular piston 19 (a seal 26 being provided).
- a micrometric thread 27 cooperates with the rod of the annular piston 19 for adjusting the relative position of the two pistons: a button 28 provided with a "Palmer” type vernier allows fine adjustment.
- the shutter of the invention comprises a main shutter 29 mounted with a seal 30 in the end of the flute body in a fixed position or, preferably adjustable by means of a device not shown.
- the main shutter 29 is honeycombed with holes 31, cylindrical (fig. 7), hexagonal (fig. 8) or others, only one of which has been shown in FIG. 6.
- the bottom of each hole consists of a piston 32 adjustable allowing to tune the length 1 of the hole on a specific frequency improving the emission of a predetermined note.
- each of these holes 31 is carefully tuned to a sensitive harmonic of the fundamental frequencies of the flute.
- each note thus has its own resonator 31.
- this system makes it possible, by slightly varying the length of the resonators 31, to individually tune the timbre and the octave ratios of each note of the flute within certain limits.
- the length of the resonators 31 can be fixed, in this case the instrument is constructed in a single tuning fork. One can even then make the plug 29 in molded plastic, the holes 31 being molded to a precalculated length.
- This embodiment gives compared to the previous a greater fixity of the notes, which will make it particularly appreciated by beginner students. Confirmed artists may prefer the first embodiment which allows greater personalization of the instrument.
- FIG. 6 illustrates a variant of FIG. 2, in which an internal piston 120 can slide inside an annular piston 119, which itself can be mounted sliding or not (as shown in FIG. 6).
- the originality of this variant resides in the convex flared shape given to the front end of the annular piston 119, analogous to a trumpet horn. Thanks to the movable piston 120 adjustable by the knurled knob 128 the length of the chamber on a harmonic of the fundamental note of the flute; experience shows that the emission of both this fundamental note and other notes is facilitated. Everything happens as if, for a given note other than the fundamental note, the air column found itself the right length of chord by taking "support" on the area of the flared part corresponding to the right length of room.
- FIGS. 7 to 10 show different shapes which can be given to the front part of the piston 119: a convex flared shape stepped in FIG. 7, a concave flared shape in FIG. 9, a divergent frustoconical shape in FIG. 8, a converging frustoconical shape in FIG. 10.
- a convex flared shape stepped in FIG. 7 a concave flared shape in FIG. 9, a divergent frustoconical shape in FIG. 8, a converging frustoconical shape in FIG. 10.

Abstract
Description
L'invention concerne un obturateur permettant de faciliter l'émission de notes prédéterminées d'une flûte traversière ou instrument analogue. On sait que dans la plupart des instruments à vent, il existe certaines notes difficiles, parce que leur émission est incertaine tant du point de vue de l'attaque que de la stabilité. C'est par exemple le cas de certaines notes basses de la flûte traversière.The invention relates to a shutter for facilitating the emission of predetermined notes from a transverse flute or the like. We know that in most wind instruments, there are certain difficult notes, because their emission is uncertain both from the point of view of attack and of stability. This is for example the case of certain low notes of the transverse flute.
Il a été proposé, dans le document DE-B-59465, de remédier à certains inconvénients de la flûte traversière en modifiant complètement le principe de base: on adapte au corps de la flûte un bec en T avec embouchure dans l'axe de la flûte, de manière à transformer celle-ci en flûte droite. Un tel instrument qui heurte complètement les habitudes des musiciens n'a jamais été développé sur le plan pratique.It has been proposed, in document DE-B-59465, to remedy certain drawbacks of the transverse flute by completely modifying the basic principle: a T-shaped spout with mouthpiece in the axis of the flute, so as to transform it into a straight flute. Such an instrument which completely offends the habits of musicians has never been developed in practical terms.
Selon une proposition du document FR-A-2 239 929 on a pensé améliorer la justesse des notes hautes d'une flûte traversière en adoptant une nouvelle forme d'obturateur. Cette forme nouvelle, si tant est qu'elle s'est avérée efficace pour le but proposée, n'a évidemment aucun rapport avec le problème envisagé par la présente invention, qui est, non celui de la justesse, mais celui de l'attaque et de la stabilité des notes, particulièrement de certaines notes basses.According to a proposal from document FR-A-2 239 929, it was thought to improve the accuracy of the high notes of a transverse flute by adopting a new form of shutter. This new form, if it has proved effective for the proposed purpose, obviously has no relation to the problem envisaged by the present invention, which is, not that of accuracy, but that of attack and the stability of the notes, particularly certain low notes.
Le but de l'invention est de proposer un obturateur qui facilite l'émission desdites notes. Ce but est atteint du fait que, selon l'invention, on dispose dans l'obturateur au moins un résonateur auxiliaire débouchant sur la colonne d'air et réalisé sous forme d'une chambre dont on accorde la longueur de façon spécifique pour faciliter l'émission d'au moins une note prédéterminée de l'instrument.The object of the invention is to propose a shutter which facilitates the emission of said notes. This object is achieved by the fact that, according to the invention, there is at least one auxiliary resonator in the obturator opening out onto the air column and produced in the form of a chamber whose length is specifically granted to facilitate '' issuance of at least one predetermined note from the instrument.
Avantageusement, on accorde la longueur de la chambre de manière que sa fréquence propre soit un logarithme binaire de la fréquence du fondamental de la note prédéterminée. Autrement dit, le résonnateur spécifique est accordé sur un harmonique sensible (une des octaves supérieures) du fondamental de la note en question.Advantageously, the length of the chamber is granted so that its natural frequency is a binary logarithm of the frequency of the fundamental of the predetermined note. In other words, the specific resonator is tuned to a sensitive harmonic (one of the upper octaves) of the fundamental of the note in question.
Pour ce faire, la chambre est avantageusement conçue sous forme d'une chambre de longueur variable qu'on règle pour l'accord. Ce réglage peut être figé par un moyen ou un autre dépendant du moyen de réglage si l'on désire un accord immuable; il peut être laissé libre si l'on veut pouvoir le changer ultérieurement, ne serait-ce que pour l'adapter aux différents diapasons en usage.To do this, the room is advantageously designed in the form of a room of variable length which is adjusted for tuning. This adjustment can be fixed by one means or another depending on the adjustment means if one wishes an immutable agreement; it can be left free if you want to be able to change it later, if only to adapt it to the different tuning forks in use.
Dans un premier exemple préféré de réalisation, le ou les résonateurs spécifiques sont constitués par une ou plusieurs chambes concentriques, avantageusement de longueur réglable.In a first preferred embodiment, the specific resonator (s) consist of one or more concentric chambers, advantageously of adjustable length.
Dans un second exemple préféré de réalisation, l'obturateur est alvéolé de trous constituant les résonateurs spécifiques. Dans une autre présentation de l'instrument, l'obturateur comporte un piston intérieur coulissant de manière réglable dans un piston annulaire dont l'extrémité frontale présente au choix une forme plane, une forme évasée convexe, une forme évasée concave, une forme évasée étagée, une forme tronconique divergente, ou une forme tronconique convergente.In a second preferred embodiment, the shutter is honeycombed with holes constituting the specific resonators. In another presentation of the instrument, the shutter comprises an internal piston sliding in an adjustable manner in an annular piston, the front end of which has a choice of a planar shape, a convex flared shape, a concave flared shape, a stepped flared shape , a diverging frustoconical form, or a converging frustoconical form.
L'invention sera mieux comprise grâce à la description qui va suivre, faite en référence aux dessins annexés sur lesquels:

- - les figures 7 à 10 montrent des variantes de forme du piston annulaire de la figure 6.
- FIG. 1 represents in longitudinal section a transverse flute with a conventional stopper,
- FIG. 2 represents a first embodiment of a flute shutter according to the invention,
- FIG. 3 represents a second embodiment of a flute shutter according to the invention,
- FIGS. 4 and 5 show from the front two variants of the second embodiment of the shutter of FIG. 3,

La figure 1 montre une flûte traversière 12 avec son embouchure 13 et, à gauche du trou d'embouchure, une cavité obturée traditionnellement par un bouchon de liège 14 serré entre deux plaques de métal 15 montées sur une tige filetée 16 dont l'extrémité 17 se visse dans un bouton moleté 18.Figure 1 shows a
Pour être étanche, le bouchon de liège 14 doit être enfoncé à force dans cette partie conique de l'embouchure.To be waterproof, the
Le coefficient de frottement du bouchon 14 étant supérieur au couple que délivre le bouton moleté 18, le système ne fonctionne pas dans le sens de l'allongement de la cavité (action de visser le bouton). Le système ne fonctionne pas dans l'autre sens non plus (action de dévisser), car dans ce cas le bouton se libère sans modifier en quoi que ce soit le volume de la cavité en question.The coefficient of friction of the
L'invention propose de remplacer ce bouchon fixe par un système de un ou plusieurs résonateurs spécifiques.The invention proposes to replace this fixed plug with a system of one or more specific resonators.
Selon un premier mode de réalisation, montré en figure 2, le bouchon classique est remplacé par un bouchon constitué d'un ou plusieurs pistons concentriques coulissant les uns dans les autres et formant ainsi des chambres concentriques de longueur réglable. Sur la figure 2, il n'est représenté que deux pistons concentriques 19 et 20. Le piston annulaire 19, muni d'une étanchéité 21 par joints toriques ou à quatre lobes, peut coulisser dans l'extrémité 22 du corps de flûte, sa position étant réglable grâce à un filetage micrométrique 23 coopérant avec une collerette terminale 24. Une surface 25 à deux ou plusieurs pans permet de tourner l'assemblage pour en régler la position tandis qu'un vernier du type «Palmer» réalisé sur cette surface permet d'en repérer avec précision la position.According to a first embodiment, shown in FIG. 2, the conventional plug is replaced by a plug made up of one or more concentric pistons sliding in one another and thus forming concentric chambers of adjustable length. In FIG. 2, only two
Le piston central 20 coulisse dans le piston annulaire 19 (une étanchéité 26 étant prévue). Un filetage micrométrique 27 coopère avec la tige du piston annulaire 19 pour régler la position relative des deux pistons: un bouton 28 muni d'un vernier type «Palmer» permet un réglage fin.The
L'émission des notes graves traditionnellement difficiles sur la flûte est grandement améliorée tout en laissant à l'artiste un «champ de liberté» dans le domaine des fréquences lui permettant un grande souplesse d'interprétation.The emission of traditionally difficult low notes on the flute is greatly improved while leaving the artist a "field of freedom" in the frequency domain allowing him great flexibility of interpretation.
Bien que présentant moins de richesse au niveau des résonateurs spécifiques mais toujours une très grande variété de timbres, on peut concevoir un piston annulaire fixe, et seulement le piston central mobile.Although having less richness at the level of the specific resonators but still a very wide variety of timbres, one can design a fixed annular piston, and only the mobile central piston.
Au contraire, on peut aussi prévoir plus de deux pistons concentriques.On the contrary, it is also possible to provide more than two concentric pistons.
Selon un autre mode de réalisation représenté fig. 3 à 5, l'obturateur de l'invention comporte un obturateur principal 29 monté avec une étanchéité 30 dans l'extrémité du corps de flûte en position fixe ou, de préférence réglable au moyen d'un dispositif non représenté. L'obturateur principal 29 est alvéolé de trous 31, cylindriques (fig. 7), hexagonaux (fig. 8) ou autres, dont un seul a été représenté sur la figure 6. Le fond de chaque trou est constitué d'un piston 32 réglable permettant d'accorder la longueur 1 du trou sur une fréquence spécifique améliorant l'émission d'une note prédéterminée.According to another embodiment shown in fig. 3 to 5, the shutter of the invention comprises a
Autrement dit, la fréquence de chacun de ces trous 31 est soigneusement accordée sur un harmonique sensible des fréquences fondamentales de la flûte.In other words, the frequency of each of these
Au lieu d'un seul résonateur ayant une fonction globale, chaque note a ainsi «son» résonateur propre 31.Instead of a single resonator with a global function, each note thus has its
Par ailleurs, ce système permet en variant légèrement la longueur des résonateurs 31 d'accorder à l'intérieur de certaines limites individuellement le timbre et les rapports d'octave de chaque note de la flûte.Furthermore, this system makes it possible, by slightly varying the length of the
Pour des instruments d'étude, bon marché, la longueur des résonateurs 31 peut être fixe, dans ce cas l'instrument est construit dans un seul diapason. L'on peut même alors réaliser le bouchon 29 en plastique moulé, les trous 31 étant moulés à une longueur précalculée.For inexpensive study instruments, the length of the
Ce mode de réalisation donne par rapport au précédent une fixité des notes plus grande, qui le fera particulièrement apprécier des élèves débutants. Les artistes confirmés pourront préférer le premier mode de réalisation qui permet une plus grande personalisation de l'instrument.This embodiment gives compared to the previous a greater fixity of the notes, which will make it particularly appreciated by beginner students. Confirmed artists may prefer the first embodiment which allows greater personalization of the instrument.
La figure 6 illustre une variante de la figure 2, dans laquelle un piston intérieur 120 peut coulisser à l'intérieur d'un piston annulaire 119, qui lui- même peut être monté coulissant ou non (comme représenté sur la figure 6). L'originalité de cette variante réside dans la forme évasée convexe donnée à l'extrémité frontale du piston annulaire 119, analogue à un pavillon de trompette. On accorde, grâce au piston mobile 120 réglable par le bouton moleté 128 la longueur de la chambre sur un harmonique de la note fondamentale de la flûte; l'expérience montre que l'émission, tant de cette note fondamentale, que des autres notes, se trouve facilitée. Tout se passe comme si, pour une note donnée autre que la note fondamentale, la colonne d'air trouvait d'elle-même la bonne longueur d'accord en prennant «appui» sur la zone de la partie évasée correspondant à la bonne longueur de chambre.FIG. 6 illustrates a variant of FIG. 2, in which an
Les figures 7 à 10 montrent différentes formes qui peuvent être données à la partie frontale du piston 119: une forme évasée convexe étagée en fig. 7, une forme évasée concave en fig. 9, une forme tronconique divergente en fig. 8, une forme tronconique convergente en fig. 10. Chacune de ces formes, avec sa propre spécificité au niveau notamment du timbre, conduit à une amélioration de l'émission des sons de la flûte.FIGS. 7 to 10 show different shapes which can be given to the front part of the piston 119: a convex flared shape stepped in FIG. 7, a concave flared shape in FIG. 9, a divergent frustoconical shape in FIG. 8, a converging frustoconical shape in FIG. 10. Each of these forms, with its own specificity, particularly in terms of timbre, leads to an improvement in the emission of the sounds of the flute.
