This cup is followed by a zone with minimum cross-sectional area (22) formed preferably by a cylindrical section and followed by a divergent cone (14). The tail (4) of the mouth piece has an external conical surface (5) nested in a convergent inlet cone (26) of the instrument. Said inlet cone forms together with the outlet cone (14) of the mouth piece a chamber (31) wherein the sound is developed. This chamber is followed by a second cylindrical section (29).

Description

EMBOUCHURE POUR UN INSTRUMENT A VENT DE LA FAMILLE DES CUIVRES, ET INSTRUMENT POURVU D'UNE TELLE EMBOUCHUREMOUTHPIECE FOR A WIND INSTRUMENT OF THE BRASS FAMILY, AND INSTRUMENT PROVIDED WITH SUCH A MOUTHPIECE
La présente invention concerne une embouchure pour un instrument à vent de la famille des cuivres, comportant un conduit axial présentant consécutivement une cuvette d'entrée, une zone à section minimale et un cône de sortie s'evasant à partir de la zone à section minimale.The present invention relates to a mouthpiece for a wind instrument of the brass family, comprising an axial duct having consecutively an inlet bowl, a zone with minimum section and an outlet cone flaring from the zone with minimum section .
L'invention concerne également un instrument à vent de la famille des cuivres, comportant une telle embouchure et un tuyau d'entrée dans lequel est emboîtée une queue de l'embouchure, ladite queue contenant le cône de sortie du conduit axial de l'embouchure, et le tuyau d'entrée comportant intérieurement un tronçon convergent s'étendant au-delà de la queue de l'embouchure jusqu'à un tronçon à section réduite, de façon à former une chambre dont la section transversale augmente puis diminue progressivement entre la zone à section minimale de l'embouchure et le tronçon à section réduite du tuyau d'entrée.The invention also relates to a wind instrument of the brass family, comprising such a mouthpiece and an inlet pipe in which is fitted a tail of the mouthpiece, said tail containing the outlet cone of the axial duct of the mouthpiece , and the inlet pipe internally comprising a convergent section extending beyond the tail of the mouth to a section of reduced section, so as to form a chamber whose cross section increases and then gradually decreases between the minimum section area of the mouthpiece and the reduced section section of the inlet pipe.
Les embouchures pour cuivres ont une section minimale qui est précédée d'une cuvette ayant généralement une forme conique ou hémisphérique. Les brevets allemands N° 252 225 et 18 561, ainsi que la demande de brevet allemand N° 3 0 4 509, décrivent de telles embouchures à cuvette dont le profil présente une courbure à variation continue. Au-delà de cette section minimale, le conduit sonore se présente sous la forme d'un cône inversé, c'est-à-dire s'evasant par rapport au sens d'écoulement de l'air, à l'intérieur d'une queue cylindrique destinée à être emboîtée dans le tuyau d'entrée de l'instrument. Avec cette forme d'embouchure classique, la production de sons aigus avec une bonne qualité sonore est assez difficile, en particulier avec les instruments qui demandent beaucoup de souffle, comme les trompes de chasse.The mouthpieces for brass instruments have a minimum section which is preceded by a bowl generally having a conical or hemispherical shape. German Patent Nos. 252,225 and 18,561, as well as German Patent Application No. 3,040,509, describe such cup mouthpieces whose profile has a continuously varying curvature. Beyond this minimum section, the sound duct is in the form of an inverted cone, that is to say widening with respect to the direction of flow of the air, inside of a cylindrical shank intended to be fitted into the inlet pipe of the instrument. With this classic form of mouthpiece, producing high tones with good sound quality is quite difficult, especially with instruments that require a lot of breath, such as the hunting horns.
La présente invention a pour but de perfectionner une telle embouchure, d'une manière permettant d'améliorer la production des sons. Un but particulier de l'invention est de permettre de diminuer l'effort physique de l'exécutant grâce à une configuration judicieuse de l'embouchure et de l'entrée de l'instrument. A cet effet, la présente invention concerne une embouchure du type indiqué plus haut, caractérisée en ce que la cuvette d'entrée comporte deux zones coniques raccordées l'une à l'autre et ayant des angles de conicité différents, à savoir une première zone ayant un premier angle de conicité relativement faible et une seconde zone ayant un second angle de conicité sensiblement plus grand que le premier.The present invention aims to improve such a mouthpiece, in a way to improve the production of sounds. A particular object of the invention is to allow the physical effort of the performer to be reduced by virtue of a judicious configuration of the mouthpiece and of the entry of the instrument. To this end, the present invention relates to a mouthpiece of the type indicated above, characterized in that the inlet bowl has two conical zones connected to one another and having different angles of conicity, namely a first zone having a relatively small first conical angle and a second region having a second conical angle substantially larger than the first.
Grâce à cette forme, la cuvette d'entrée maintient les lèvres dans une position où elles sont libres, mais bien centrées en face de l'orifice formé par la zone à section minimale, et elle permet de concentrer favorablement vers cette zone l'air envoyé par la bouche du musicien. Dans une forme de réalisation particulièrement avantageuse, la zone à section minimale a une forme cylindrique dont la longueur est d'au moins deux fois le diamètre.Thanks to this shape, the inlet bowl keeps the lips in a position where they are free, but well centered opposite the orifice formed by the zone with minimum section, and it allows the air to be favorably concentrated towards this zone. sent by the musician's mouth. In a particularly advantageous embodiment, the zone with minimum cross section has a cylindrical shape whose length is at least twice the diameter.
Suivant un autre aspect, la présente invention concerne un instrument à vent du genre indiqué plus haut, caractérisé en ce que la zone à section minimale de l'embouchure a une forme cylindrique et en ce que ledit tronçon à section réduite du tuyau d'entrée a une forme cylindrique et est suivi d'un tronçon conique divergent, de sorte que ladite chambre se trouve entre deux tronçons cylindriques de conduit.According to another aspect, the present invention relates to a wind instrument of the type indicated above, characterized in that the zone with minimum cross-section of the mouthpiece has a cylindrical shape and in that said section with reduced cross-section of the inlet pipe has a cylindrical shape and is followed by a divergent conical section, so that said chamber is between two cylindrical sections of conduit.
Ledit tronçon convergent peut avantageusement avoir une longueur approximativement égale à celle du cône divergent de sortie de l'embouchure, et/ou un angle de conicité approximativement égal à celui dudit cône divergent de sortie de l'embouchure.Said converging section may advantageously have a length approximately equal to that of the divergent cone leaving the mouth, and / or a conical angle approximately equal to that of said divergent cone leaving the mouth.
De préférence, la queue de l'embouchure a une surface extérieure conique agencée pour s'ajuster, dans le tuyau d'entrée, sur une surface intérieure conique qui définit ledit tronçon convergent au-delà de la queue de l'embouchure.Preferably, the tail of the mouth has a conical outer surface arranged to fit, in the inlet pipe, on a conical inner surface which defines said converging section beyond the tail of the mouth.
La présente invention sera mieux comprise à l'aide de la description suivante de quelques exemples de réalisation d'une embouchure d'une trompe de chasse selon l'invention, en référence aux dessins annexés, dans lesquels : la figure 1 est une vue en coupe longitudinale d'une première forme d'une embouchure pour trompe de chasse,The present invention will be better understood with the aid of the following description of some exemplary embodiments of a mouthpiece of a hunting horn according to the invention, with reference to the appended drawings, in which: FIG. 1 is a view in longitudinal section of a first form of a mouthpiece for a hunting horn,
la figure 2 est une vue en coupe longitudinale d'une deuxième forme d'une embouchure pour trompe de chasse,FIG. 2 is a view in longitudinal section of a second form of a mouthpiece for a hunting horn,
la figure 3 est une vue en coupe longitudinale d'une entrée d'une trompe de chasse équipée d'une embouchure selon la figure 1 etFIG. 3 is a view in longitudinal section of an inlet of a hunting horn equipped with a mouthpiece according to FIG. 1 and
- la figure 4 représente la même trompe de chasse, équipée d'une embouchure selon la figure 2.FIG. 4 represents the same hunting horn, equipped with a mouthpiece according to FIG. 2.
L'embouchure 1 représentée à la figure 1 a une forme générale classique comprenant un calice 2 destiné à recevoir les lèvres de l'exécutant, une collerette médiane 3 formant un arrêt, et une queue 4 destinée à être emboîtée dans un tuyau d'entrée d'un instrument tel qu'une trompe de chasse ou tout autre instrument de la famille des cuivres. Alors que les embouchures classiques ont habituellement une queue cylindrique, la queue 4 a une surface extérieure 5 de forme conique convergente, c'est-à-dire que son diamètre est plus petit à l'extrémité libre 6 de la queue qu'au voisinage de la collerette 3.The mouth 1 shown in Figure 1 has a general conventional shape comprising a cup 2 intended to receive the lips of the performer, a central collar 3 forming a stop, and a tail 4 intended to be fitted into an inlet pipe an instrument such as a hunting horn or any other instrument of the brass family. While conventional mouthpieces usually have a cylindrical tail, the tail 4 has an outer surface 5 of converging conical shape, that is to say that its diameter is smaller at the free end 6 of the tail than in the vicinity of the collar 3.
Le calice 2 contient une cuvette d'entrée 7 s'étendant entre un bord d'entrée arrondi 8 et une zone 10 où la section transversale intérieure de l'embouchure est minimale, à proximité de l'emplacement de la collerette 3. La cuvette 7 est délimitée latéralement par deux surfaces coniques 1 1 et 12. La première surface conique 1 1 est relativement courte et elle a une faible conicité, son angle total d'ouverture étant de préférence inférieur à 10°. La seconde surface conique 12 a un angle d'ouverture nettement plus grand, généralement supérieur à 40°. Une brève zone arrondie 13 est prévue pour raccorder les surf aces 1 1 et 12.The chalice 2 contains an inlet bowl 7 extending between a rounded inlet edge 8 and a zone 10 where the internal cross section of the mouth is minimal, near the location of the collar 3. The bowl 7 is delimited laterally by two conical surfaces 1 1 and 12. The first conical surface 1 1 is relatively short and has a small conicity, its total opening angle is preferably less than 10 °. The second conical surface 12 has a significantly larger opening angle, generally greater than 40 °. A short rounded zone 13 is provided for connecting the surf aces 11 and 12.
De même, la zone à section minimale 10 a un profil longitudinal arrondi, afin d'éviter une arête vive. Cette zone 10 est suivie d'un cône divergent 14 qui s'étend jusqu'à l'extrémité 6 de l'embouchure, où l 'épaisseur de la paroi est relativement mince.Similarly, the minimum cross-sectional area 10 has a rounded longitudinal profile, in order to avoid a sharp edge. This zone 10 is followed by a divergent cone 14 which extends to the end 6 of the mouth, where the thickness of the wall is relatively thin.
Cette f orme du conduit axial de l'embouchure, et en particulier de la cuvette 7, s'avère particulièrement favorable pour permettre au sonneur de jouer les notes aiguës, difficiles à obtenir avec les embouchures commercialisées actuellement. On pense que ce résultat est dû à un eff et de ventouse obtenu par la forme en double cône de la cuvette 7 dont la première surface conique 11 forme une sorte de rebord autour des lèvres du sonneur. D'autre part, cette embouchure permet une réduction sensible de l'effort physique du sonneur. La forme convergente/diver¬ gente de part et d'autre de la zone à section minimale 10 joue probablement un rôle dans ce phénomène.This form of the axial duct of the mouthpiece, and in particular of the bowl 7, proves to be particularly favorable for enabling the bell ringer to play the high notes, difficult to obtain with the mouthpieces currently marketed. It is believed that this result is due to an effect and suction obtained by the double cone shape of the bowl 7 whose first conical surface 11 forms a kind of rim around the lips of the bell ringer. On the other hand, this mouthpiece allows a significant reduction in the physical effort of the ringer. The convergent / divergent shape on either side of the minimum cross-sectional area 10 probably plays a role in this phenomenon.
L'embouchure 21 illustrée par la figure 2 présente un grand nombre de caractéristiques similaires à celles de l'embouchure 1, c'est pourquoi on a utilisé les mêmes numéros de référence pour les éléments semblables. La seule différence essentielle est que la zone à section minimale est formée par un tronçon cylindrique 22 reliant la seconde surface conique 12 au cône divergent 14. Ce tronçon cylindrique 22 a de préférence une longueur de l'ordre de 4 à 5 fois son diamètre. Cette forme permet d'obtenir de meilleures harmoniques dans les sons, en même temps qu'une amplification des sons et une facilité dans la précision de l'obtention des notes.The mouthpiece 21 illustrated in FIG. 2 has a large number of characteristics similar to those of the mouthpiece 1, this is why the same reference numbers have been used for similar elements. The only essential difference is that the minimum cross-sectional area is formed by a cylindrical section 22 connecting the second conical surface 12 to the divergent cone 14. This cylindrical section 22 preferably has a length of the order of 4 to 5 times its diameter. This form makes it possible to obtain better harmonics in the sounds, at the same time as an amplification of the sounds and an ease in the precision of obtaining the notes.
Les figures 3 et 4 montrent un tuyau d'entrée 24 d'une même trompe de chasse, équipée respectivement de l'embouchure 1 et de l'embouchure 21. L'extrémité du tuyau 24 qui reçoit l'embouchure est un fourreau renforcé extérieurement par une bague 25 et contenant un tronçon de conduit convergent 26 ayant une surface intérieure conique convergente 27 qui s'étend entre l'extrémité libre 28 du tuyau et une zone à section rétrécieFigures 3 and 4 show an inlet pipe 24 of the same hunting horn, equipped respectively with the mouth 1 and the mouth 21. The end of the pipe 24 which receives the mouth is an externally reinforced sheath by a ring 25 and containing a section of converging conduit 26 having a converging conical inner surface 27 which extends between the free end 28 of the pipe and an area of narrowed section
29 au-delà de laquelle le conduit intérieur du tuyau s'évase de nouveau sous la forme d'un cône divergent 30. La surface conique convergente 27 a la même conicité que la surface extérieure 5 de la queue 4 de l'embouchure, pour permettre l'emb'oîtement de celle-ci. Toutefois, l'embouchure ne s'emboîte que sur une certaine longueur de la surface29 beyond which the inner conduit of the pipe flares again in the form of a divergent cone 30. The converging conical surface 27 has the same conicity as the outer surface 5 of the tail 4 of the mouth, for allow nesting thereof. However, the mouthpiece only fits over a certain length of the surface
27 dont à peu près la moitié reste non couverte entre l'extrémité 6 de l'embouchure et la zone 29 à section réduite. On a ainsi une sorte de chambre 31 formée par les surfaces coniques opposées 14 et 27 entre les zones de plus petite section 10 ou 22 et 29. Les surfaces coniques 14 et 27 peuvent avoir approximativement le même angle de conicité et/ou la même longueur. Ainsi, le profil longitudinal de la chambre 31 apparaît comme un losange dont on aurait coupé les pointes. Au point de vue acoustique, cette chambre assure une certaine rétention de l'air et une amplification du son à la sortie de l'embouchure, ce qui permet une réduction remarquable de l'effort physique du sonneur et, par là même, une amélioration de la qualité des sons qu'il peut produire. La meilleure efficacité est obtenue avec la forme de la figure 4, où la chambre 31 est précédée et suivie des tronçons cylindriques 22 et 29.27, about half of which remains uncovered between the end 6 of the mouth and zone 29 with reduced section. There is thus a sort of chamber 31 formed by the opposite conical surfaces 14 and 27 between the zones of smaller section 10 or 22 and 29. The conical surfaces 14 and 27 can have approximately the same angle of conicity and / or the same length . Thus, the longitudinal profile of the chamber 31 appears as a rhombus whose tips have been cut. From an acoustic point of view, this chamber ensures a certain retention of air and an amplification of the sound at the outlet of the mouth, which allows a remarkable reduction of the physical effort of the ringer and, by that same, an improvement. the quality of the sounds it can produce. The best efficiency is obtained with the shape of FIG. 4, where the chamber 31 is preceded and followed by the cylindrical sections 22 and 29.
La présente invention n'est pas limitée aux exemples de réalisation décrits ci-dessus, mais elle s'étend à toutes modifications ou variantes évidentes pour un homme de l'art. Elle s'applique également à tout autre instrument de la famille des cuivres comportant ce genre d'embouchure, par exemple la trompette, le clairon, les trombones, etc. The present invention is not limited to the embodiments described above, but it extends to all modifications or variants obvious to a person skilled in the art. It also applies to any other instrument of the brass family including this kind of mouthpiece, for example the trumpet, the bugle, the trombones, etc.
