Abstract

Dans cette trompette à pistons linéaires ou rotatifs, notamment trompette en si bémol, ut, ré ou mi bémol, le bas de la potence d'accord (11) comporte un élargissement conique et le tube inférieur (13) de la coulisse d'accord coulisse à l'extérieur du tube (6) solidaire du jeu de piston, lequel tube solidaire (6) est raccourci par rapport à l'extrémité amont du tube inférieur (13) de la coulisse (5) en position de butée, le reste de la perce étant sensiblement cylindrique et de même diamètre (D). Si l'on divise la potence d'accord en six sections de longueur d'axe (15) égale, l'élargissement conique commence dans la cinquième section (ef), l'extrémité amont du tube (6) solidaire du jeu des pistons est située juste au-delà d'une septième section de même longueur d'axe (15) que les autres.In this trumpet with linear or rotary pistons, in particular trumpet in B flat, C, D or E flat, the bottom of the tuning stem (11) has a conical widening and the lower tube (13) of the tuning slide slide outside the tube (6) integral with the piston set, which integral tube (6) is shortened relative to the upstream end of the lower tube (13) of the slide (5) in the stop position, the rest of the bore being substantially cylindrical and of the same diameter (D). If the tuning stem is divided into six sections of equal axis length (15), the conical widening begins in the fifth section (ef), the upstream end of the tube (6) secured to the set of pistons is located just beyond a seventh section of the same axis length (15) as the others.

Description

L'invention concerne les trompettes d'orchestre à pistons linéaires ou rotatifs.The invention relates to orchestral trumpets with linear or rotary pistons.

Le problème de la justesse de ces instruments fait depuis longtemps l'objet de recherches permanentes et on pourra se reporter à ce sujet à l'ouvrage "Musical Acoustics : Piano and Wind Instruments" par Earle L. KENT paru en 1977 chez DOWDEN, HUTCHINSON & ROSS, INC., STROUDSBURG, Pennsylvania, U.S.A. et également aux brevets des Etats-Unis n° 3.507.181 et 2.987.950.The problem of the accuracy of these instruments has been the subject of permanent research for a long time and we can refer to this subject in the work "Musical Acoustics: Piano and Wind Instruments" by Earle L. KENT published in 1977 by DOWDEN, HUTCHINSON & ROSS, INC., STROUDSBURG, Pennsylvania, USA and also in U.S. Patents Nos. 3,507,181 and 2,987,950.

De façon plus particulière, il a été constaté que toutes les trompettes de construction classique du type des trompettes en si bémol, ut, ré, ou mi bémol, présentent le défaut caractéristique d'avoir un groupe de trois notes trop basses (ré 4, ré dièse 4, mi 4 pour la trompette en ut), ce dont se plaignent les trompettistes.More specifically, it has been found that all the trumpets of conventional construction of the type of trumpets in B flat, C, D, or E flat, have the characteristic defect of having a group of three notes that are too low (D 4, D sharp 4, E 4 for the trumpet in C), which the trumpeters complain about.

La généralité de ce défaut a conduit certains à affirmer que ces notes sont "fausses par nature",tandis que d'autres, comme KENT dans son brevet des Etats-Unis n° 2.987.950 propose des palliatifs relativement compliqués.The generality of this defect has led some to assert that these notes are "false by nature", while others, such as KENT in its US Patent No. 2,987,950 offers relatively complicated workarounds.

Le but de l'invention est de proposer une trompette, notamment une trompette en si-bémol, ut, ré ou mi-bémol, ne présentant pas le défaut constaté, tout en conservant, pour l'essentiel, les caractéristiques d'une trompette classique.The object of the invention is to provide a trumpet, in particular a trumpet in B-flat, C, D or E-flat, not exhibiting the defect observed, while essentially retaining the characteristics of a trumpet classic.

Ce but est atteint par le fait que le bas de la potence d'accord de la trompette comporte un élargissement conique et que le tube inférieur de la coulisse d'accord coulisse à l'extérieur du tube solidaire du jeu de piston, au lieu de coulisser à l'intérieur, comme cela se fait jusqu'ici. D'autre part,le tube solidaire du jeu de piston est raccourci par rapport à sa longueur classique, c'est-à-dire qu'il est raccourci par rapport à l'extrémité amont du tube inférieur de la coulisse en position de butée.This object is achieved by the fact that the bottom of the trumpet's tuning stem has a conical widening and that the lower tube of the tuning slide slides outside the tube secured to the piston set, instead of slide inside, as has been done so far. On the other hand, the tube integral with the piston set is shortened by compared to its conventional length, that is to say that it is shortened relative to the upstream end of the lower tube of the slide in the stop position.

En dehors de l'élargissement conique conforme à l'invention et de l'extrémité amont du tube inférieur de la coulisse d'accord, la perce est sensiblement cylindrique et de même diamètre depuis le tube supérieur de la coulisse d'accord jusqu'au départ du coude du pavillon.Apart from the conical widening according to the invention and the upstream end of the lower tube of the tuning slide, the bore is substantially cylindrical and of the same diameter from the upper tube of the tuning slide to departure from the elbow of the pavilion.

Les effets de la modification proposée s'expliquent de la façon suivante. On sait, dans la mise au point acous.tique des instruments à vent, qu'augmenter le diamètre d'un tube sur un ventre de vitesse équivaut à modifier l'impédance du tube sur cette longueur d'ondes et la fréquence monte.The effects of the proposed change are explained as follows. It is known, in the acoustic development of wind instruments, that increasing the diameter of a tube on a belly of speed is equivalent to modifying the impedance of the tube on this wavelength and the frequency increases.

Inversement, la note baisse si on augmente le diamètre sur un ventre de pression.Conversely, the note drops if the diameter is increased on a pressure belly.

Or, le calcul fait par le Demandeur des longueurs d'ondes effectives à l'intérieur d'une trompette en ut (les résultats se transposent immédiatement sur les trompettes en si bémol, ré ou mi bémol) donne la présence de ventres de vitesse pour les notes mi 4, ré dièse 4, et ré 4 au bas de la potence de la coulisse d'accord, espacés d'environ 16 mm à partir de la cheminée de clé d'eau (si elle existe) vers les pistons.However, the calculation made by the Applicant of the effective wavelengths inside a trumpet in C (the results are immediately transposed on the trumpets in B flat, D or E flat) gives the presence of velocity bellies for the notes E 4, D sharp 4, and D 4 at the bottom of the stem of the tuning slide, spaced approximately 16 mm from the water key chimney (if it exists) towards the pistons.

A cet endroit, dans le montage traditionnel, le tube inférieur solidaire de la potence d'accord coulisse à l'intérieur du tube inférieur solidaire du jeu de piston.At this point, in the traditional assembly, the lower tube secured to the tuning bracket slides inside the lower tube secured to the piston set.

Dans le montage conforme à l'invention, le tube inférieur de la coulisse d'accord coulisse à l'extérieur du tube solidaire du jeu de pistons.In the assembly according to the invention, the lower tube of the tuning slide slides outside the tube secured to the set of pistons.

Cette conception originale permet d'élargir la perce au niveau de ventres de vitesse particuliers .. des notes à réhausser, et a un effet extrêmement surprenant et positif sur la courbe de justesse de l'instrument: en effet, alors qu'on aurait pu craindre que l'élargissement réalisé ne fût bénéfique qu'aux seules notes à réhausser, et nuisible à la justesse d'autres notes dont des ventres de vitesse ou de pression sont également situés dans la zone corrigée, il s'avère que beaucoup d'autres notes légèrement fausses dans un instrument classique sont rétablies à leur juste valeur.This original design widens the bore at the level of specific speed bellies. notes to be raised, and has an extremely surprising and positive effect on the accuracy curve of the instrument: indeed, when one might have feared that the enlargement achieved would be beneficial only to the notes to be raised, and detrimental to the accuracy of other notes whose velocity or pressure bellies are also located in the corrected area, it turns out that many other slightly false notes in a classical instrument are restored to their fair value.

L'invention est d'autant plus appréciable que les études menées jusque là concluaient généralement à l'impossibilité de rien changer à la perce de la trompette (cf. le brevet américain précité 2.987.950). 'The invention is all the more appreciable since the studies carried out so far generally concluded that it was impossible to change anything with the piercing of the trumpet (cf. the aforementioned American patent 2,987,950). ''

Les caractéristiques et avantages de l'invention seront mieux compris à la lecture de la description suivante faite en référence aux dessins annexés sur lesquels :

  • - la figure 1 représente en perspective une trompette traditionnelle ;
  • - la figure 2 représente en coupe la coulisse d'accord d'une trompette traditionnelle ;
  • - la figure 3 représente en coupe la coulisse d'accord d'une trompette conforme à l'invention ;
  • - la figure 4 représente sur un même graphique les courbes de justesse respective d'une trompette en ut traditionnelle et d'une trompette en ut conforme à l'invention.
The characteristics and advantages of the invention will be better understood on reading the following description made with reference to the accompanying drawings in which:
  • - Figure 1 shows in perspective a traditional trumpet;
  • - Figure 2 shows in section the tuning slide of a traditional trumpet;
  • - Figure 3 shows in section the tuning slide of a trumpet according to the invention;
  • - Figure 4 shows on the same graph the respective accuracy curves of a traditional C trumpet and a C trumpet according to the invention.

La trompette traditionnelle 1 de la figure 1 comprend à la suite l'embouchure 2, la branche d'embouchure 3 s'élargissant coniquement jusqu'au départ 4 de la perce. Celle-ci reste cylindrique tout le long de la coulisse d'accord 5, du tube 6 solidaire du jeu de pistons 7, jusqu'au départ 8 du coude du pavillon.The traditional trumpet 1 in FIG. 1 further comprises the mouth 2, the mouth branch 3 widening conically until the start 4 of the bore. The latter remains cylindrical all along the tuning slide 5, of the tube 6 secured to the set of pistons 7, until the start 8 of the bell bend.

Les figures 2 et 3 comparent les coulisses d'accord 5 d'une trompette en ut classique (fig. 2) et selon l'invention (fig. 3). Naturellement, ce qui est dit pour la trompette en ut sera à transposer pour les trompettes d'une autre tonalité.Figures 2 and 3 compare the tuning slides 5 of a classical C trumpet (Fig. 2) and according to the invention (Fig. 3). Naturally, what is said for the trumpet in C will be transposed for the trumpets of another tone.

Dans le montage traditionnel, le tube supérieur 9 de la coulisse d'accord 5, relié par une virole 10 à la potence d'accord 11 coulisse à l'intérieur du tube 12 terminant la branche d'embouchure 3, et le tube inférieur 13 de la coulisse d'accord 5, relié par une virole 14 à la potence d'accord 11, coulisse à l'intérieur du tube 6 solidaire du jeu de piston.In the traditional assembly, the upper tube 9 of the tuning slide 5, connected by a ferrule 10 to the tuning bracket 11 slides inside the tube 12 terminating the mouth branch 3, and the lower tube 13 of the tuning slide 5, connected by a ferrule 14 to the tuning bracket 11, slides inside the tube 6 secured to the piston set.

Les calculs de longueurs d'onde montrent que, si l'on divise la potence 11 en six intervalles égaux (ab, bc, cd, de, ef, fg) comptés sur l'axe central 15 de la potence, d'amont en aval, à partir de la division a correspondant au départ de courbure de la potence jusqu'à la division g correspondant à la fin de la courbure de la potence, les ventres de vitesse du mi 4 et du ré dièse sont sensiblement dans les sections droites correspondant aux divisions f et g. Le ventre du ré 4 se trouve dans une section droite correspondant à une division supplémentaire h, de même intervalle que les précédentes, située au-delà de la potence d'accord. La division f (le ventre du mi 4) tombe généralement sur la cheminée 16 de clé d'eau 17,quand elle est présente ( la clé d'eau est visible sur la fig. 1, et la cheminée de clé d'eau n'a été représentée que sur la fig. 3). La perce, dont le diamètre nominal D est défini en 4, est cylindrique et uniforme tout le long de la coulisse d'accord.The wavelength calculations show that, if the stem 11 is divided into six equal intervals (ab, bc, cd, de, ef, fg) counted on the central axis 15 of the stem, from upstream to downstream, from division a corresponding to the start of curvature of the stem to division g corresponding to the end of the curvature of the stem, the velocity bellies of E 4 and D sharp are substantially in the straight sections corresponding to divisions f and g. The belly of the re 4 is in a cross section corresponding to an additional division h, with the same interval as the previous ones, located beyond the tuning stem. The division f (the belly of mi 4) generally falls on the chimney 16 of water key 17, when it is present (the water key is visible in fig. 1, and the chimney of water key n 'has been shown only in Fig. 3). The bore, whose nominal diameter D is defined in 4, is cylindrical and uniform all along the tuning slide.

Selon l'invention, on élargit coniquement le bas de la potence 11 de façon à englober les ventres de vitesse situés en f, g, et h. L'élargissement conique commence donc à partir de la cinquième section ou intervalle ef jusqu'à l'extrémité g de la potence, qui se raccorde par la virole 14 au tube inférieur 13 de la coulisse d'accord 5, lequel coulisse cette fois-ci à l'extérieur du tube 6 solidaire du jeu de piston, dont le diamètre intérieur est pris égal au diamètre nominal D de la perce, toujours défini en 4.According to the invention, the bottom of the stem 11 is conically widened so as to encompass the speed bellies situated at f, g, and h. Conical enlargement therefore begins from the fifth section or inter valle ef to the end g of the bracket, which is connected by the ferrule 14 to the lower tube 13 of the tuning slide 5, which slides this time outside the tube 6 secured to the piston set , whose internal diameter is taken equal to the nominal diameter D of the bore, always defined in 4.

Afin que le tuyau à l'endroit du ventre de vitesse situé en h (le ré 4) ait son diamètre augmenté, le tube solidaire 6 est raccourci par rapport à l'extrémité amont du tube inférieur 13 de la coulisse en position de butée (position des figures 2 ou 3). Autrement dit, l'élargissement conique de la perce commence à peu près au milieu de l'intervalle ef, se poursuit jusqu'en §, après quoi la perce reste cylindrique sur l'intervalle gh et sur à peu près la moitié de l'intervalle suivant (non représenté), avant de revenir au diamètre nominal D.So that the pipe at the speed belly located in h (the re 4) has its increased diameter, the integral tube 6 is shortened relative to the upstream end of the lower tube 13 of the slide in the stop position ( position of figures 2 or 3). In other words, the conical widening of the bore begins approximately in the middle of the interval ef, continues until § , after which the bore remains cylindrical over the interval gh and over approximately half of the next interval (not shown), before returning to nominal diameter D.

Sur une trompette en ut, l'écartement des divisions est d'environ 16 mm. Aussi, pour une trompette en ut, possédant en plus une cheminée 16 de clé d'eau 17, on peut retenir qu'on commence l'élargissement conique à environ 8mm au-dessus de la cheminée 16 et qu'on raccourcit le tube 6 solidaire du jeu de piston d'environ 10 mm.On a trumpet in C, the spacing of the divisions is approximately 16 mm. Also, for a trumpet in C, having in addition a chimney 16 of water key 17, it can be remembered that the conical widening begins about 8mm above the chimney 16 and that the tube 6 is shortened secured to the piston clearance of approximately 10 mm.

La figure 7 est un graphique portant en abscisses les notes N, écrites selon la notation anglo- saxonne pour plus de commodité (A = la, B * si, etc.)avec le chiffrage français des octaves ; en ordonnée est portée la déviation S par rapport à la note juste (réglée sur le diapason à 442 Hz), ladite déviation étant exprimée en Savarts (c'est-à-dire en 1/25èmes de demi-ton).FIG. 7 is a graph on the abscissa the notes N, written according to the Anglo-Saxon notation for convenience (A = la, B * si, etc.) with the French coding of the octaves; on the ordinate is the deviation S relative to the right note (adjusted on the tuning fork at 442 Hz), said deviation being expressed in Savarts (that is to say in 1 / 25ths of a semitone).

La courbe en pointillés est établie pour une trompette classique. On y remarque un certain nombre de notes fausses, et notamment les notes ré 4, ré dièse 4 et mi 4 ( ou D4 , D dièse 4 et E 4) qui sont trop basses.The dotted curve is established for a classical trumpet. We note there a certain number of false notes, and in particular the notes re 4, d sharp 4 and mi 4 (or D 4 , D sharp 4 and E 4) which are too low.

La courbe en traits pleins montre la courbe de justesse de la même trompette après modification conforme à l'invention. On remarque que non seulement les trois notes ré 4, ré dièse 4 et mi 4 sont revenues au diapason, mais que d'autres notes également, soit trop basses, soit trop hautes auparavant, sont recalées sur le diapason. Sur ce graphique établi à dessein sans rectification de justesse de la part du musicien, les notes fa dièse 2, sol 2, do dièse 3 et ré 3 restent trop hautes, mais elles sont rectifiées, en jeu normal,par les coulisses mobiles des premier et troisième pistons munies traditionnellement d'anneaux (tel que 18, fig.l) ou de systèmes à bascule prévus à cet effet et dont l'utilisation fait partie du jeu normal de l'instrument.The curve in solid lines shows the accuracy curve of the same trumpet after modification in accordance with the invention. We note that not only the three notes re 4, d sharp 4 and mi 4 returned to the tuning fork, but that other notes also, either too low or too high before, are readjusted on the tuning fork. On this graph drawn up on purpose without correcting on the part of the musician, the notes F sharp 2, G 2, C sharp 3 and D 3 remain too high, but they are corrected, in normal play, by the moving slides of the first and third pistons traditionally provided with rings (such as 18, fig.l) or rocker systems provided for this purpose and the use of which is part of the normal play of the instrument.

Ainsi l'invention permet de remédier à un défaut général de construction des trompettes.Thus, the invention makes it possible to remedy a general defect in the construction of the trumpets.
