Description

EMBOUCHURE POUR INSTRUMENT DE MUSIQUE A VENT La présente invention concerne une embouchure pour instrument de musique à vent, notamment pour trompette, cornet, bugle, cor, trombone, tuba, ainsi que tous les instruments en cuivre. The present invention relates to a mouthpiece for a wind musical instrument, in particular for trumpet, cornet, bugle, horn, trombone, tuba, as well as all copper instruments.
Les embouchures de ce genre d' instruments sont usuellement constituées en matériau métallique ou en alliages de matériaux métalliques.The mouthpieces of this type of instrument are usually made of metallic material or alloys of metallic materials.
Elles ont l'avantage d'être très stables et résistantes à la déformation mais présentent par ailleurs des inconvénients importants.They have the advantage of being very stable and resistant to deformation but also have significant drawbacks.
Tout d'abord, elles sont froides au toucher, étant donné que la chaleur corporelle est rapidement évacuée ou dissipée par conduction thermique. Il en résulte, pour le musicien jouant dans des locaux froids ou à l'extérieur, un refroidissement des lèvres qui est gênant et désagréable.First, they are cool to the touch, since body heat is quickly dissipated or dissipated by thermal conduction. This results, for the musician playing in cold rooms or outside, a cooling of the lips which is annoying and unpleasant.
Ensuite, des dommages peuvent être causés aux parties ou pièces métalliques de la denture du musicien, par electrolyse due aux sels ou complexes métalliques transmis à la salive par l'embouchure.Then, damage can be caused to the metal parts or pieces of the musician's teeth, by electrolysis due to the salts or metal complexes transmitted to the saliva by the mouthpiece.
Pour remédier à ces inconvénients, le brevet français N° 2 069 273 décrit une embouchure constituée en bois de densité moyenne, imprégné ou imbibé au moins partiellement avec une substance organique polymérisée.To remedy these drawbacks, French Patent No. 2,069,273 describes a mouthpiece made of medium density wood, impregnated or at least partially soaked with an organic polymerized substance.
L'imprégnation, qui est rendue possible grâce à la densité moyenne des bois employés (notamment érable, bouleau, poirier, aulne ou tilleul) , vise à limiter le gonflement du bois sous l'effet de l'humidité. Une imprégnation complète du bois est préférée pour l'obtention d'une très bonne stabilité de forme, correspondant au mieux à toutes les exigences ou conditions qui sont imposées à une embouchure.The impregnation, which is made possible thanks to the average density of the woods used (in particular maple, birch, pear, alder or linden), aims to limit the swelling of the wood under the effect of humidity. Complete impregnation of the wood is preferred in order to obtain very good shape stability, which best corresponds to all the requirements or conditions which are imposed on a mouthpiece.
De telles embouchures se ressentent comme tièdes au toucher en raison de la mauvaise conductibilité thermique de leur matériau constitutif et ne dégagent aucune substance toxique pour les dents du musicien.Such mouthpieces feel lukewarm to the touch due to poor conductivity thermal of their constituent material and do not release any substance toxic to the teeth of the musician.
Elles présentent en revanche l'inconvénient important de ne produire qu'une nuance de sonorité spécifique, guère avantageuse, quelle que soit l'essence de bois employée, étant donné que la matière synthétique qui les recouvre limite les possibilités de vibration du bois à une gamme de fréquences très restreinte. Il s'agit en fait d'une embouchure essentiellement en matière synthétique, dans laquelle le bois ne sert que de support à la matière synthétique. En pratique, ces embouchures ne sont pas employées et ce sont les embouchures métalliques précitées, avec les inconvénients qu'elles impliquent, qui sont couramment utilisées. La présente invention vise à remédier à l'ensemble de ces inconvénients.On the other hand, they have the significant disadvantage of producing only a nuance of specific sound, hardly advantageous, whatever the species of wood used, since the synthetic material which covers them limits the possibilities of vibration of the wood to a very limited frequency range. It is in fact a mouthpiece essentially made of synthetic material, in which the wood only serves as a support for the synthetic material. In practice, these mouthpieces are not used and it is the aforementioned metal mouthpieces, with the drawbacks which they imply, which are commonly used. The present invention aims to remedy all of these drawbacks.
A cette fin, l'embouchure qu'elle concerne est caractérisée en ce qu'elle est constituée en bois brut de densité supérieure à 0,75 et est assemblée à un tube métallique de raccordement à l'instrument.To this end, the mouthpiece it relates to is characterized in that it is made of raw wood with a density greater than 0.75 and is assembled to a metal tube for connection to the instrument.
La possibilité de vibration du bois brut, non limitée par un quelconque revêtement, permet l'obtention de sonorités particulières, riches et agréables, dont la nuance peut être choisie en fonction de l'essence de bois utilisée pour constituer l'embouchure. Ainsi, le musicien peut choisir une sonorité appropriée aux oeuvres jouées, au moyen d'embouchures interchangeables réalisées en différentes essences de bois. Le remplacement d'une embouchure par une autre peut être envisagé au cours d'une même représentation, dans la mesure où l'artiste doit jouer des oeuvres ayant des rythmes et des sonorités différents.The possibility of vibration of the raw wood, not limited by any coating, makes it possible to obtain particular, rich and pleasant tones, the shade of which can be chosen according to the species of wood used to form the mouthpiece. Thus, the musician can choose a sound appropriate to the works played, by means of interchangeable mouthpieces made of different wood species. The replacement of one mouthpiece by another can be envisaged during the same performance, insofar as the artist must play works with different rhythms and sounds.
La densité du bois employé et les essences spécifiquement sélectionnées pour constituer ces embouchures influent sur l'obtention des sonorités précitées et permettent également d'éviter le phénomène de gonflement du bois sous l'effet de l'humidité.The density of the wood used and the species specifically selected to constitute these mouths influence the obtaining of the tones. mentioned above and also make it possible to avoid the phenomenon of swelling of the wood under the effect of humidity.
Avantageusement, les essences de bois qui sont sélectionnées pour constituer les embouchures selon 1 ' invention sont les suivantes :Advantageously, the species of wood which are selected to constitute the mouthpieces according to the invention are the following:
- bois de rose (dalbergia) , pour l'obtention d'une nuance de son dite "rondeur riche" ;- rosewood (dalbergia), to obtain a nuance of its so-called "rich roundness";
- bois de violette (dalbergia nigra) , pour l'obtention d'une nuance de son dite "généreuse et distinguée" ;- violet wood (dalbergia nigra), to obtain a nuance of its so-called "generous and distinguished";
- bois d'ébène (grassiflora) , pour l'obtention d'une nuance de son dite "puissante/élégante" ;- ebony (grassiflora), to obtain a nuance of its so-called "powerful / elegant";
- buis (buxus) , pour l'obtention d'une nuance de son dite "douce" ; - coco-bolo (dalbergia) , pour l'obtention d'une nuance de son dite "majestueuse" ;- boxwood (buxus), to obtain a shade of so-called "soft" sound; - coconut-bolo (dalbergia), to obtain a nuance of its so-called "majestic";
- ziricote (Mexique), pour l'obtention d'une nuance de son dite "noble" ;- ziricote (Mexico), to obtain a nuance of its so-called "noble";
- olivier (olea europea) , pour l'obtention d'une nuance de son dite "brillante".- olive tree (olea europea), to obtain a nuance of its so-called "brilliant".
Pour sa bonne compréhension, l'invention va être à nouveau décrite ci-après, en référence au dessin schématique annexé représentant, à titre d'exemples non limitatifs, deux formes de réalisation préférées de l'embouchure qu'elle concerne.For a good understanding, the invention will be described again below, with reference to the appended schematic drawing representing, by way of nonlimiting examples, two preferred embodiments of the mouth it relates to.
Dans ce dessin, la figure 1 est une vue d'une embouchure et de son tube de raccordement à l'instrument, selon une première forme de réalisation, en coupe longitudinale et à l'état démonté ; la figure 2 est une vue similaire à la figure 1 de ces deux éléments, mais à l'état monté et la figure 3 est une vue d'une embouchure et de son tube de raccordement à l'instrument, assemblés l'un à l'autre, selon une deuxième forme de réalisation. Les figures représentent des embouchures 1 pour instrument de musique à vent, notamment pour trompette, cor, trombone ou tuba, avec leur tube 2 de raccordement à 1 ' instrument. Les embouchures 1 sont réalisées en bois brut de densité supérieure à 0,75, tandis que les tubes 2 sont réalisés en métal.In this drawing, Figure 1 is a view of a mouthpiece and its connection tube to the instrument, according to a first embodiment, in longitudinal section and in the disassembled state; Figure 2 is a view similar to Figure 1 of these two elements, but in the assembled state and Figure 3 is a view of a mouthpiece and its connection tube to the instrument, assembled one to the other, according to a second embodiment. The figures represent mouthpieces 1 for wind musical instrument, in particular for trumpet, horn, trombone or tuba, with their tube 2 for connection to one instrument. The mouthpieces 1 are made of raw wood with a density greater than 0.75, while the tubes 2 are made of metal.
La possibilité de vibration du bois brut, non limitée par un quelconque revêtement du bois, permet l'obtention de sonorités particulières, riches et agréables, dont la nuance varie en fonction de l'essence de bois utilisée pour constituer l'embouchure 1. Ainsi, le musicien peut choisir une sonorité appropriée aux oeuvres jouées, au moyen d'embouchures 1 réalisées en différentes essences de bois.The possibility of vibration of the raw wood, not limited by any coating of the wood, makes it possible to obtain particular, rich and pleasant tones, the shade of which varies according to the species of wood used to form the mouthpiece 1. Thus , the musician can choose a sound appropriate to the works played, by means of mouthpieces 1 made of different wood species.
La densité du bois employé et les essences spécifiquement sélectionnées pour constituer ces embouchures 1 influent sur l'obtention des sonorités obtenues et permettent également de limiter le phénomène de gonflement du bois sous l'effet de l'humidité. Les embouchures 1 sont avantageusement réalisées dans les essences de bois suivantes :The density of the wood used and the species specifically selected to constitute these mouths 1 influence the obtaining of the tones obtained and also make it possible to limit the phenomenon of swelling of the wood under the effect of humidity. The mouthpieces 1 are advantageously made from the following types of wood:
- bois de rose (dalbergia), pour l'obtention d'une nuance de son dite "rondeur riche" ; - bois de violette (dalbergia nigra) , pour l'obtention d'une nuance de son dite "généreuse et distinguée" ;- rosewood (dalbergia), to obtain a nuance of its so-called "rich roundness"; - violet wood (dalbergia nigra), to obtain a nuance of its so-called "generous and distinguished";
- bois d'ébène (grassiflora) , pour l'obtention d'une nuance de son dite "puissante/élégante" ; - buis (buxus) , pour l'obtention d'une nuance de son dite "douce" ;- ebony (grassiflora), to obtain a nuance of its so-called "powerful / elegant"; - boxwood (buxus), to obtain a shade of so-called "soft" sound;
- coco-bolo (dalbergia), pour l'obtention d'une nuance de son dite "majestueuse" ;- coconut-bolo (dalbergia), to obtain a nuance of its so-called "majestic";
- ziricote (Mexique) , pour l'obtention d'une nuance de son dite "noble" ; - olivier (olea europea) , pour l'obtention d'une nuance de son dite "brillante".- ziricote (Mexico), to obtain a nuance of its so-called "noble"; - olive tree (olea europea), to obtain a nuance of its so-called "brilliant".
Dans la forme de réalisation de l'invention représentée aux figures 1 et 2, l'embouchure 1 comprend, du côté opposé à la cuvette 5, un alésage coaxial au conduit 6 qui la traverse, dans lequel est engagée une douille taraudée 3, fixée par collage à l'embouchure 1 et pouvant être vissée sur l'extrémité filetée 2a du tube 2.In the embodiment of the invention shown in Figures 1 and 2, the mouth 1 comprises, on the side opposite to the bowl 5, a bore coaxial with the conduit 6 which passes through it, in which is engaged a threaded socket 3, fixed by bonding to the mouth 1 and can be screwed onto the threaded end 2a of the tube 2.
L'embouchure 1 est ainsi rendue aisément amovible par rapport au tube 2, de telle sorte qu'elle peut être facilement et rapidement interchangée en fonction de l'oeuvre à jouer et du son que le musicien désire obtenir.The mouthpiece 1 is thus made easily removable with respect to the tube 2, so that it can be easily and quickly interchanged depending on the work to be played and the sound that the musician wishes to obtain.
Avantageusement, la longueur de la partie filetée 2a du tube 2 est égale à celle de la douille 3 de manière à assurer une continuité des conduits 6 traversant l'embouchure 1 et 7 traversant le tube 2.Advantageously, the length of the threaded part 2a of the tube 2 is equal to that of the sleeve 3 so as to ensure continuity of the conduits 6 passing through the mouth 1 and 7 passing through the tube 2.
Dans la forme de réalisation représentée à la figure 3, l'embouchure 1 comprend un prolongement tubulaire 4 sur lequel est emmanchée une douille filetée 3 destinée à être vissée dans l'ouverture taraudée du tubeIn the embodiment shown in Figure 3, the mouth 1 includes a tubular extension 4 on which is fitted a threaded sleeve 3 intended to be screwed into the threaded opening of the tube
2.2.
Il va de soi que l'invention n'est pas limitée aux deux formes de réalisation représentées au dessin à titre d'exemples, mais qu'elle en embrasse au contraire toutes les variantes de réalisation.It goes without saying that the invention is not limited to the two embodiments shown in the drawing by way of examples, but on the contrary embraces all the variant embodiments thereof.
Ainsi, l'embouchure peut n'être pas démontable par rapport à son tube de raccordement. Dans ce cas, c'est l'ensemble embouchure 1-tube 2 qui doit être interchangé pour modifier le son obtenu par l'instrument. Thus, the mouthpiece may not be removable from its connection tube. In this case, it is the 1-tube 2 mouthpiece assembly which must be interchanged to modify the sound obtained by the instrument.
