Abstract

The disclosed mute is a mouthpiece provided with a diaphragm (1) limiting the passage of the volume of air and of the sound, in front of which a sound expansion chamber (2) is mounted wherein the energy is dispersed, letting only the low amplitude waves pass through the diaphragm (1). The air volume in said expansion chamber (2) makes the reed (4) vibrate more easily, particularly for the low-pitched notes. Furthermore, the adjustment of the air volume within said expansion chamber (2) provides for the accuracy of the tones. This mute may be provided with a sound compression channel (3) arranged before the expansion chamber (2), which favours the passage through the diaphragm (1) of high frequencies to the detriment of low frequencies, thereby facilitating the octave skip. The mute is provided with air discharge channels (5-10) which are independent of the sound circuit.

Description

Sourdine pour saxophones et autres instruments à anche simple Mute for saxophones and other simple reed instruments
DescriptionDescription
Cette invention mécanique se rapporte à la diminution du volume sonore, donc la diminution de l'amplitude du son, des instruments à bec, comme les saxophones, les clarinettes, etcThis mechanical invention relates to the decrease in sound volume, therefore the decrease in the amplitude of sound, of beak instruments, such as saxophones, clarinets, etc.
La diminution de l'amplitude sonore obtenue par les sourdines mécaniques disponibles qui sont montées à la fin de l'instrument, ne sont pas efficaces pour les instruments percés d'ouvertures d'où la majeure partie du volume sonore s'échappe Surtout les instruments puissants, comme les saxophones, sont gênants pour l'entourage Le seul moyen connu par l'inventeur pour diminuer sensiblement le volume sonore de ces instruments est le « modificateur d'amplitude et de fréquence pour instrument à vent » dont la demande de brevet, déposée à Berne en Suisse, porte le numéro 03546/95 Ce modificateur d'amplitude et de fréquence peut être employé comme sourdine quand la baisse de fréquence, résultant de l'absorption d'amplitude par le système d'assourdissement, est corrigée par un élargissement substantiel et par la réduction de la longueur de la colonne d'air Un dosage adéquat des éléments du modificateur permet de retrouver la justesse des tons Aucune autre forme de sourdine pour instrument à anche n'est connueThe reduction in the sound amplitude obtained by the available mechanical mutes which are mounted at the end of the instrument, are not effective for instruments pierced with openings from which the major part of the sound volume escapes. powerful, like the saxophones, are annoying for the entourage The only means known by the inventor to decrease appreciably the sound volume of these instruments is the “amplifier of amplitude and frequency for wind instrument” whose patent application, registered in Bern in Switzerland, carries the number 03546/95 This amplifier of amplitude and frequency can be used as mute when the decrease in frequency, resulting from the absorption of amplitude by the system of deactivation, is corrected by a substantial enlargement and reduction of the length of the air column Adequate dosage of the elements of the modifier makes it possible to regain the correctness of the tones No other form of so reed instrument urine is unknown
Cette invention est une embouchure qui se caractérise par un diaphragme (fig.1, 1), réduisant sensiblement le passage de l'air La diminution du volume sonore est obtenue en empêchant le musicien déjouer fort L'anche, génératrice du son ne peut vibrer sensiblement, car le diaphragme (fig 1 ; 1 ) ne permet qu'un faible débit d'air Devant ce diaphragme (fig 1; 1) le son se détend dans une chambre d'expansion sonore (fig 1, 2) qui â un triple but' premièrement, la vague sonore est dispersée, ce qui diminue l'amplitude du son II en résulte qu'une onde sonore à amplitude réduite passe par le diaphragme (fig 1, 1) Deuxièmement, le volume d'air dans cette chambre d'expansion (fig 1, 2), sert de coussin pneumatique L'excédent d'énergie sonore rebondit. Cela permet à l'anche de vibrer malgré le faible débit d'air, en particulier dans le registre des notes graves Troisièmement, l'ajustement du volume d'air dans cette chambre d'expansion (fig 1, 2) permet de retrouver les volumes d'air nécessaire dans l'ensemble de l'instrument pour garantir la justesse des tons Devant la chambre d'expansion (fig.1 , 2 ), un canal de compression (fig.1 , 3) est placé pour facilité le saut d'octave et pour mieux garder le timbre, permettant également de réduire encore plus le diamètre du diaphragme (fig.l, 1) et donc déjouer à un niveau sonore plus bas Ce canal de compression (fig 1, 3) est en fait un rétrécissement progressif du début du bec, nettement plus prononcé que celui que l'on trouve dans les becs usuels Ce canal de compression (fig 1, 3) dirige le son vers le diaphragme pour favoriser le passage des fréquences hautes, parce que les fréquences aiguës ne se dispersent pas aussi facilement que les fréquences graves Pour palier au surplus d'air que l'instrumentiste ne peut faire passer par l'instrument de façon normale, un ou plusieurs canaux d'évacuation d'air (fig 2, 5 et 6) sont prévus en dehors du circuit sonore Les (ou la) prises d'air (fig.2, 7 et 8) se situent dans la partie du bec qui se tient dans la bouche Le ou les canaux d'évacuation d'air (fig.2, 5 et 6) se terminent par des l'orifices de sortie d'air (fig.2, 9 et 10) se trouvant sur la partie du bec qui reste en dehors de la boucheThis invention is a mouthpiece which is characterized by a diaphragm (fig. 1, 1), appreciably reducing the passage of air The reduction in sound volume is obtained by preventing the musician from playing loudly The reed, generator of sound cannot vibrate noticeably, because the diaphragm (fig 1; 1) allows only a low air flow Before this diaphragm (fig 1; 1) the sound relaxes in a room sound expansion (fig 1, 2) which has a triple purpose 'firstly, the sound wave is dispersed, which reduces the amplitude of the sound II results that a sound wave at reduced amplitude passes through the diaphragm (fig 1 , 1) Second, the volume of air in this expansion chamber (fig 1, 2) serves as a pneumatic cushion. The excess sound energy rebounds. This allows the reed to vibrate despite the low air flow, especially in the register of low notes Third, adjusting the air volume in this expansion chamber (fig 1, 2) allows to find the air volumes required throughout the instrument to guarantee the correctness of the tones In front of the expansion chamber (fig. 1, 2), a compression channel (fig. 1, 3) is placed to facilitate jumping octave and to better keep the timbre, also allowing to further reduce the diameter of the diaphragm (fig.l, 1) and therefore foil at a lower sound level This compression channel (fig 1, 3) is actually a progressive narrowing of the beginning of the beak, much more pronounced than that found in the usual beaks This compression channel (fig 1, 3) directs the sound towards the diaphragm to favor the passage of high frequencies, because the high frequencies do not disperse as easily as low frequencies To overcome in excess of air that the instrumentalist cannot pass through the instrument in a normal way, one or more air evacuation channels (fig 2, 5 and 6) are provided outside the sound circuit Les (or the ) air intakes (fig. 2, 7 and 8) are located in the part of the spout which is held in the mouth The air outlet channel (s) (fig. 2, 5 and 6) end in the air outlet holes (fig. 2, 9 and 10) located on the part of the spout which remains outside the mouth
Cette sourdine se différencie du modificateur d'amplitude et de fréquence pour instruments à vent mentionné plus haut, par le fait que son principe de fonctionnement est totalement différent En effet cette invention-ci empêche l'instrumentiste de générer un volume sonore élevé en réduisant le passage de l'air, tandis que le modificateur d'amplitude et de fréquence diminue un son généré normalement au niveau du bec, par absorption à un stade ultérieur. En outre cette invention-ci est placée dans le bec, qui est la cavité où le son se forme, tandis que les éléments du modificateur d'amplitude et de fréquence se monte dans le bocal ou le barillet qui, ensemble avec le corps de l'instrument, forme la partie d'amplification sonore de l'instrumentThis mute differs from the amplitude and frequency modifier for wind instruments mentioned above, by the fact that its operating principle is totally different. Indeed, this invention prevents the instrumentalist from generating a high sound volume by reducing the passage of air, while the amplitude and frequency modifier decreases a sound normally generated at the beak, by absorption at a later stage. Furthermore this invention is placed in the spout, which is the cavity where the sound is formed, while the amplitude and frequency modifier elements are mounted in the jar or the barrel which, together with the body of the instrument, forms the sound amplification part of the instrument
Cette invention à l'avantage de permettre au musicien déjouer sur les clefs de son instrument d'origine à un niveau sonore moins dérangeant. En outre une partie du volume d'air de la chambre d'expansion permet de tenir un petit microphone sans altérer la justesse des tons. Cette invention a l'avantage que le diamètre du ou des canaux d'évacuation d'air peuvent être réglés (pré-réglés ou réglables) pour obtenir des débits d'air différent, sans devoir changer l'ouverture du bec au niveau de l'anche.This invention has the advantage of allowing the musician to foil the keys of his original instrument at a less disturbing sound level. In addition, part of the volume of air in the expansion chamber makes it possible to hold a small microphone without altering the accuracy of the tones. This invention has the advantage that the diameter of the exhaust air channel (s) can be adjusted (pre-adjusted or adjustable) to obtain different air flows, without having to change the opening of the nozzle at the level of the 'reed.
Cette invention est décrite ci-après à l'aide d'un exemple de sourdine pour saxophone, et à l'aide de références aux dessins annexés, dans lesquels:This invention is described below using an example of a mute for saxophone, and using references to the accompanying drawings, in which:
La figure 1 est une vue en coupe longitudinale de l'invention, à angle droit de l'ancheFigure 1 is a longitudinal sectional view of the invention, at right angles to the reed
La figure 2 est une vue en coupe longitudinale de l'invention suivant le plan AA' montré sur la figure 1 .FIG. 2 is a view in longitudinal section of the invention along the plane AA 'shown in FIG. 1.
La figure 1 montre le bec muni de son anche et de sa ligature (fig.1 ; 4). Le débit d'air est limité par le diaphragme (fig.1, 1). Le volume d'air dans la chambre d'expansion (fig l; 2) ensemble avec le volume d'air dans le canal de compression (fig.1; 3) permet de générer des sons malgré le faible diamètre du diaphragme (fig l; 1). La chambre d'expansion (fig. l; 2) est longue et fine pour garantir un retour lent des ondes, ce qui permet de générer facilement les notes graves. Le canal de compression sonore (fig.1; 3) dirige les ondes aiguës vers le diaphragme (fig.1; 1) pour faciliter le saut d'octave et garder le timbre. Les canaux d'évacuation d'air ne sont pas visibles sur la figure 1.Figure 1 shows the beak with its reed and its ligature (fig. 1; 4). The air flow is limited by the diaphragm (fig. 1, 1). The volume of air in the expansion chamber (fig l; 2) together with the volume of air in the compression channel (fig. 1; 3) makes it possible to generate sounds despite the small diameter of the diaphragm (fig l ; 1). The expansion chamber (fig. L; 2) is long and thin for guarantee a slow return of the waves, which makes it possible to easily generate the low notes. The sound compression channel (fig. 1; 3) directs the high waves towards the diaphragm (fig. 1; 1) to facilitate the octave jump and keep the timbre. The exhaust air channels are not visible in Figure 1.
La figure 2 montre le bec sur lequel sont dessinés deux canaux d'évacuation d'air (fig.2; 5 et 6) indépendants des conduits sonore, et dont les prises d'air (fig.2; 7 et 8) se situent sur les bords du bec à un niveau qui se tient à l'intérieur de la bouche du musicien, et dont les l'orifice de sortie d'air (fig.2; 9 et 10) se situent à un niveau du bec qui reste à l'extérieur de la bouche. Le surplus d'air peut donc être évacué par ces deux canaux (fig.2; 5 et 6) . Figure 2 shows the spout on which are drawn two air exhaust channels (fig. 2; 5 and 6) independent of the sound ducts, and whose air intakes (fig. 2; 7 and 8) are located on the edges of the beak at a level which is inside the musician's mouth, and whose air outlet orifice (fig. 2; 9 and 10) are located at a level of the beak which remains outside the mouth. The excess air can therefore be evacuated by these two channels (fig. 2; 5 and 6).

Concerne : Sourdine pour saxophones et autres instruments à anche simpleApplies to: Mute for saxophones and other simple reed instruments
Le musicien utilisant une embouchure normale, peut jouer moins fort en réduisant la pression de l'air produite par les poumons. En faisant cela, il réduit le débit de l'air et par conséquent, aussi la vitesse de l'air, ainsi que l'énergie disponible à l'anche pour vibrer Différence de pression, vitesse de l'air, débit de l'air et énergie libérée sont intrinsèquement liésThe musician, using a normal mouthpiece, can play less loudly by reducing the pressure of the air produced by the lungs. By doing this, it reduces the air flow and therefore also the air speed, as well as the energy available to the reed to vibrate Pressure difference, air speed, air flow air and released energy are intrinsically linked
Suivant cette invention, c'est le diaphragme (fig.1;1) qui freine le passage de l'air, de telle sorte que le débit d'air agissant sur l'extrémité de l'anche (fig. î;4) est diminué Par conséquent, pour une même ouverture, moins d'énergie est disponible à l'anche (fig.1;4) pour vibrerAccording to this invention, it is the diaphragm (fig. 1; 1) which slows down the passage of air, so that the air flow acting on the end of the reed (fig. 1; 4) is reduced Consequently, for the same opening, less energy is available to the reed (fig. 1; 4) to vibrate
L'approche scientifique du phénomène pneumatique qui est la base de cette invention, peut s'expliquer comme suit.The scientific approach to the pneumatic phenomenon which is the basis of this invention can be explained as follows.
La pression de l'air produite par le musicien dans la bouche, se détend partiellement à l'extrémité de l'anche (fig.1;4) et partiellement au niveau du diaphragme (fig.1 ,1) Car en freinant le passage de l'air, le diaphragme (fig.1,1) agit comme un réducteur de pression, gardant une pression intermédiaire dans la cavité entre l'ouverture située à l'extrémité de l'anche (fig.1,4) et le diaphragme (fig.1,1). L'anche (fig.1 ;4) est donc soumise à une différence de pression moindre et par conséquent le débit d'air ainsi que la vitesse de l'air, est diminuée comparée à une embouchure normale, pour une même pression pneumatique dans la boucheThe air pressure produced by the musician in the mouth, partially relaxes at the end of the reed (fig. 1; 4) and partially at the diaphragm (fig. 1, 1) Because by slowing the passage air, the diaphragm (fig.1,1) acts as a pressure reducer, keeping an intermediate pressure in the cavity between the opening located at the end of the reed (fig.1,4) and the diaphragm (fig.1,1). The reed (fig. 1; 4) is therefore subjected to a lesser pressure difference and consequently the air flow rate as well as the air speed, is reduced compared to a normal mouthpiece, for the same pneumatic pressure in the mouth
Suivant cette invention, le diaphragme (fig.1,1) n'a aucune fonction d'absorption ou d'assourdissement sonore. Il est préférable de fabriquer le diaphragme (fig.1,1 ) en un matériau dur pour justement éviter toute interférence acoustique indésirable par le diaphragme (fig 1,1)According to this invention, the diaphragm (fig.1,1) has no sound absorption or muffling function. It is preferable to make the diaphragm (fig.1,1) from a hard material to precisely avoid any unwanted acoustic interference by the diaphragm (fig 1,1)
Cette invention se différencie de l'invention de Christian Debecq (Belgique 889500A déposée en janvier 82) par le fait que ce au moins un diaphragme (fig.1,1) est un réducteur de débit pneumatique et non pas un système d'assourdissement sonore L'invention de Christian Debecq, quand à elle, se situe purement dans le domaine acoustique, qui tente d'assourdir un son normalement généré, par absorption ultérieure du son ou par modification de l'effet vibratoire de la colonne d'air de l'instrumentThis invention differs from the invention of Christian Debecq (Belgium 889500A filed in January 82) by the fact that this at least one diaphragm (fig.1,1) is a pneumatic flow reducer and not a sound deafening system As for Christian Debecq's invention, it is purely in the acoustic domain, which attempts to mute a sound normally generated, by subsequent absorption of sound or by modification of the vibratory effect of the air column of the 'instrument
Le titre de cette invention se justifie par le résultat obtenu et non pas par son mode de fonctionnement The title of this invention is justified by the result obtained and not by its mode of operation
