Description

INSTRUMENT DE MUSIQUE A CORDES ET TABLE  MUSICAL INSTRUMENT WITH STRINGS AND TABLE
D' HARMONIE  HARMONY
ARRIERE-PLAN TECHNOLOGIQUE DE L'INVENTION BACKGROUND OF THE INVENTION
On connaît des instruments de musique à cordes comportant une table d'harmonie, telle que la guitare, le violon ou le piano. La table d'harmonie est reliée aux cordes par l'intermédiaire d'un transducteur, du type chevalet ou tout autre dispositif équivalent, et se trouve ainsi excitée lorsque l'on fait vibrer les cordes. La table d'harmonie rayonne alors dans l'air ambiant pour produire un son en correspondance avec la vibration des cordes .  Stringed musical instruments with a soundboard such as guitar, violin or piano are known. The soundboard is connected to the strings through a transducer, bridge type or any other equivalent device, and is thus excited when vibrating the strings. The soundboard then radiates in the ambient air to produce a sound in correspondence with the vibration of the strings.
Diverses tentatives ont été effectuées pour amélio¬ rer des tels instruments. Dans le document US7288706, il a été proposé d'utiliser plusieurs tables d'harmonies, chacune d'entre elles étant excitées par une partie des cordes. Ainsi, chaque table d'harmonie est optimisée pour amplifier les vibrations des cordes associées. Cependant, il se peut que l'attaque des cordes conduise à la vibration simultanée de plusieurs tables d'harmonie. Les tables d'harmonie ainsi sollicitées peuvent émettre des ondes sonores qui interfèrent les unes avec les autres de sorte à atténuer l'émission de son dans certaines gammes de fréquences. Dans le document DE 843 050, il a également été proposé que la table d' harmonie soit séparée en deux zones au moyen d'une fente. Les deux zones peuvent présenter des comportements vibratoires distincts si elles sont associées à des moyens de rigidification différentiels, comme par exemple des frontières externes non symétriques ou des renforts non symétriques. Toutefois, le transducteur de la guitare est en deux parties indé- pendantes, chaque partie étant associée à l'une seule des zones de sorte que l'attaque d'une corde ne fait vibrer que la zone correspondante de la table d'harmonie. Various attempts have been made to Amelio ¬ rer of such instruments. In US7288706, it has been proposed to use several tables of harmonies, each of them being excited by a part of the strings. Thus, each soundboard is optimized to amplify the vibrations of the associated strings. However, it is possible that the attack of the strings leads to the simultaneous vibration of several soundboards. The soundboards thus solicited can emit sound waves that interfere with each other so as to attenuate the sound emission in certain frequency ranges. In DE 843 050 it has also been proposed that the soundboard be split into two areas by means of a slot. The two zones may exhibit distinct vibration behaviors if they are associated with differential stiffening means, such as non-symmetrical external boundaries or unsymmetrical reinforcements. However, the guitar transducer has two independent parts. pendent, each part being associated with only one of the zones so that the attack of a string vibrates only the corresponding zone of the soundboard.
OBJET DE L' INVENTION  OBJECT OF THE INVENTION
L' invention a pour objet de proposer un instrument, de musique à cordes et table d'harmonie présentant une émission de son homogène sur une gamme de fréquence donnée. The object of the invention is to propose an instrument for string music and soundboard having a homogeneous sound emission over a given frequency range.
BREVE DESCRIPTION DE L'INVENTION  BRIEF DESCRIPTION OF THE INVENTION
En vue de la réalisation de ce but, on propose un instrument de musique à cordes et table d'harmonie, dans lequel la table d' harmonie est excitée par les cordes au moyen d'un transducteur et est associée à des moyens de rigidification différentiels définissant sur la table d'harmonie au moins deux zones présentant des comportements vibratoires complémentaires, les deux zones étant séparées au moyen d'une fente s' étendant selon une fron¬ tière commune aux deux zones. Selon l'invention, le transducteur s'étend à cheval sur la fente pour être relié aux deux zones de la table d'harmonie, de sorte que les deux zones sont excitées simultanément lorsque l'une des cordes est attaquée. In order to achieve this goal, a string and soundboard musical instrument is proposed, in which the soundboard is excited by the strings by means of a transducer and is associated with differential stiffening means. defining on the soundboard at least two zones having complementary vibratory behavior, the two zones being separated by a slot extending in a fron ¬ RESPECT common to the two zones. According to the invention, the transducer extends astride the slot to be connected to the two areas of the soundboard, so that the two zones are excited simultaneously when one of the strings is attacked.
Ainsi, la table d'harmonie est rigidifiée de sorte à présenter au moins deux zones, toutes deux excitées simultanément, dont le comportement vibratoire est complémentaire. Pour une même excitation, celle des zones qui présentera un creux de réponse, et donc qui ne pourra émettre qu'un son étouffé ou amoindri, sera aidée par l'autre zone, qui au contraire présentera un plein de réponse, de sorte que cette autre zone émettra un son qui compensera la faiblesse du son émis par la première zone. Contrairement à une guitare de l'art antérieur telle que celle illustrée dans le document DE 843 050, les différentes zones de la table d'harmonie sont excitées simultanément. Il est ainsi possible de profiter pleinement des comportements vibratoires complémentaires des deux zones. Dans le document DE 843 050, l'excitation d'une zone de la table d'harmonie par la moitié du transducteur peut entraîner indirectement l'excitation de la deuxième zone mais alors le son émis par cette deuxième zone sera très atténué par rapport à celui émis par la première zone. Thus, the soundboard is stiffened so as to have at least two zones, both excited simultaneously, whose vibratory behavior is complementary. For the same excitation, that of the zones which will present a hollow of answer, and thus which will be able to emit only a muffled or reduced sound, will be helped by the other zone, which on the contrary will present a full of answer, so that this another zone will emit a sound that will compensate for the weakness of the sound emitted by the first zone. Unlike a guitar of the prior art such as that illustrated in DE 843 050, the different areas of the soundboard are excited simultaneously. It is thus possible to take full advantage of the complementary vibratory behaviors of the two zones. In the document DE 843 050, the excitation of a zone of the sounding board by the half of the transducer can indirectly cause the excitation of the second zone but then the sound emitted by this second zone will be very attenuated compared to the one emitted by the first zone.
Dans l'invention, le son de l'instrument de musique est ressenti comme étant plus plein sur une gamme de fréquence élargie.  In the invention, the sound of the musical instrument is felt to be fuller over an enlarged frequency range.
A titre d'illustration, des simulations ont été réalisées pour comparer les qualités acoustiques d'une guitare de l'art antérieur et d'une guitare selon l'invention. La figure 4 illustre une simulation montrant l'impédance globale d'une guitare selon l'invention (courbe A) et d'une guitare classique (courbe B) , c'est- à-dire d'une guitare sans fente à une table d'harmonie, en fonction de la fréquence. Il est clairement visible sur cette figure que le rayonnement est plus uniforme pour la plage de fréquences concernée pour la guitare selon l'invention que pour la guitare classique.  As an illustration, simulations have been made to compare the acoustic qualities of a guitar of the prior art and a guitar according to the invention. FIG. 4 illustrates a simulation showing the overall impedance of a guitar according to the invention (curve A) and of a classical guitar (curve B), that is to say from a guitar without a slot to a table harmony, depending on the frequency. It is clearly visible in this figure that the radiation is more uniform for the frequency range concerned for the guitar according to the invention than for the classical guitar.
Il conviendra de faire coïncider, autant que faire se peut des pleins de réponse fréquentielle de l' une des zones à des creux de réponse fréquentielle de l'autre zone et réciproquement.  As far as possible, the full frequency response of one of the zones should coincide with frequency response valleys of the other zone and vice versa.
BREVE DESCRIPTION DES DESSINS La figure 4 a déjà été évoquée et illustre une simulation montrant l'impédance de deux guitares en fonction de la fréquence. BRIEF DESCRIPTION OF THE DRAWINGS Figure 4 has already been mentioned and illustrates a simulation showing the impedance of two guitars as a function of frequency.
L' invention sera mieux comprise à la lumière de la description qui suit d'un exemple de réalisation non limitatif de l'invention, en référence aux figures suivantes :  The invention will be better understood in the light of the following description of a nonlimiting exemplary embodiment of the invention, with reference to the following figures:

La figure 2 est une vue de la face interne de la table d'harmonie, munie de son barrage ;  Figure 2 is a view of the inner face of the soundboard, with its dam;
la figure 3 est un graphe montrant l'impédance de chacune des zones de la table d'harmonie de la guitare de la figure 1 en fonction de la fréquence.  Figure 3 is a graph showing the impedance of each of the areas of the soundboard of the guitar of Figure 1 as a function of frequency.
DESCRIPTION DETAILLEE D'UN MODE DE REALISATION DE L' INVENTION  DETAILED DESCRIPTION OF AN EMBODIMENT OF THE INVENTION
L' invention est ici illustrée en application à une guitare. Il est bien évident que l'invention s'applique à tout instrument à cordes excitant, via un transducteur, une table d'harmonie, comme un violon ou un piano.  The invention is here illustrated in application to a guitar. It is obvious that the invention applies to any exciting string instrument, via a transducer, a soundboard, such as a violin or a piano.
La guitare illustrée à la figure 1 comprend de façon connue en soi une caisse de résonance 1 fermée dans sa partie postérieure par une table d' harmonie 2 sur laquelle est rapporté un chevalet 3. Des cordes sont tendues entre l'extrémité d'un manche 5 solidaire de la caisse 1 et le chevalet 3. Les cordes n'ont pas été représentées ici, pour plus de clarté. L'attaque d'une ou plusieurs cordes provoque la vibration de celles-ci, cette vibration étant transmise via le chevalet 3 à la table d'harmonie 2 qui se met elle-même à vibrer et ainsi rayonner dans l'air ambiant. Comme cela est visible à la figure 2, la table d'harmonie 2 est rigidifiée par un barrage 6 fait de cotes 7 (seules certaines d'entre elles sont référencées) collées sur la face interne de la table d'harmonie. Selon l'invention, le barrage 6 est conçu pour définir sur ]a table d'harmonie deux zones 2A et 2B qui présentent des comportements vibratoires distincts mais complémentaires, comme cela sera explicité plus loin. En pratique ici, les deux zones 2A, 2B s'étendent chacune entre le bord périphérique de la table d' harmonie 2 et un axe de symétrie central X. On constate immédiatement que le barrage 6 a une configuration dissymétrique, conférant à chacune des deux zones 2A, 2B, un comportement vibratoire singulier. The guitar illustrated in FIG. 1 comprises, in a manner known per se, a sound box 1 closed in its posterior part by a soundboard 2 on which is attached a bridge 3. Ropes are stretched between the end of a neck 5 integral with the body 1 and the bridge 3. The strings have not been shown here for clarity. The attack of one or more strings causes the vibration thereof, this vibration being transmitted via the bridge 3 to the soundboard 2 which itself starts to vibrate and thus radiate in the ambient air. As can be seen in FIG. 2, the soundboard 2 is stiffened by a dam 6 made of dimensions 7 (only some of them are referenced) glued to the internal face of the soundboard. According to the invention, the dam 6 is designed to define on the soundboard two zones 2A and 2B which have distinct but complementary vibratory behaviors, as will be explained below. In practice here, the two zones 2A, 2B each extend between the peripheral edge of the soundboard 2 and a central axis of symmetry X. It is immediately apparent that the dam 6 has an asymmetrical configuration, conferring on each of the two zones 2A, 2B, singular vibratory behavior.
Ici, une fente 8 a été pratiquée dans la table d'harmonie 2 le long de la frontière entre les deux zones 2A,2B, en l'occurrence l'axe de symétrie X. La fente s'étend ici depuis l'ouïe jusqu'à proximité du bord de la table d'harmonie. Chacune des zones 2A,2B présente un bord libre qui est raidi par un raidisseur rapporté ( 9A et 9B respectivement) .  Here, a slot 8 has been made in the soundboard 2 along the border between the two zones 2A, 2B, in this case the axis of symmetry X. The slot extends here from the hearing up to 'close to the edge of the soundboard. Each of the zones 2A, 2B has a free edge which is stiffened by an attached stiffener (9A and 9B respectively).
On remarquera que les deux zones sont excitées simultanément lors de l'attaque des cordes, puisque le chevalet 3 s'étend sur les deux zones 2A, 2B pour transmettre à celles-ci les vibrations des cordes. Les zones 2A et 2B rayonnent donc simultanément.  It will be noted that the two zones are excited simultaneously during the attack of the strings, since the bridge 3 extends over the two zones 2A, 2B to transmit to them the vibrations of the strings. Zones 2A and 2B thus radiate simultaneously.
On remarquera également que la table d' harmonie ne comporte plus d'ouïe ou de rosace, la fente 8 en tenant lieu .  It will also be noted that the soundboard no longer has a hearing or rosette, the slot 8 taking the place of it.
Selon l'invention, les zones 2A et 2B sont dotées d'un comportement vibratoire complémentaire de sorte que, au moins dans une plage de fréquences donnée, un creux de réponse fréquentielle de l'une des zones corresponde un plein de réponse de réponse fréquentielle . Ceci peut être visualisé sur le graphe de la figure 3 qui montre le principe de l'accord fréquentiel des deux zones. Aux creux de l'une des courbes correspond un plein de l'autre, par exemple dans les intervalles II, 12 ou 13 où, de façon alternative, la réponse en impédance de l'une des zones vient compenser celle de l'autre des zones . According to the invention, the zones 2A and 2B are provided with a complementary vibratory behavior so that, at least in a given frequency range, a trough of Frequency response of one of the areas corresponds to a full frequency response response. This can be visualized on the graph of Figure 3 which shows the principle of the frequency agreement of the two zones. In the hollows of one of the curves corresponds a full of the other, for example in the intervals II, 12 or 13 where, alternatively, the impedance response of one of the zones compensates for that of the other of the areas.
Cette disposition permet un rayonnement plus uniforme dans toute la plage de fréquences concernée, et donne à l'instrument un son plus plein, plus homogène. On pourra par exemple régler les comportements vibratoires des deux zones de sorte que l'une réponde mieux pour les fréquences basses, et l'autre réponde mieux pour les fréquences aiguës.  This arrangement allows a more uniform radiation throughout the frequency range concerned, and gives the instrument a fuller, more homogeneous sound. For example, the vibratory behavior of the two zones may be adjusted so that one responds better to the low frequencies, and the other responds better to the high frequencies.
On appréciera que ce comportement diffère sensiblement de la simple vibration d'une table d'harmonie selon des modes antisymétriques pour certaines fréquences. En effet, dans ce cas, des portions de la table d'harmonie sont animées de battements en opposition de phase. Dans ces modes, seuls ceux présentant une symétrie impaire rayonnent une onde acoustique en champ lointain. Cependant, ces mêmes portions sont susceptibles de battre en phase dans des vibrations à symétrie paire, et dans ce cas, aucun son n'est rayonné en champ lointain. Au contraire, dans l'invention, on tente de concevoir les deux zones de sorte que, si l'une d'elle ne vibre pas ou peu pour certaines fréquences, l'autre prenne le relais et vibre pour compenser l'absence de production sonore de la première zone. Bien entendu, on évitera que les deux zo- nés rayonnent en opposition de phase pour une fréquence donnée . It will be appreciated that this behavior differs substantially from the simple vibration of a soundboard in antisymmetric modes for certain frequencies. Indeed, in this case, portions of the soundboard are animated beats in phase opposition. In these modes, only those with odd symmetry radiate an acoustic wave in the far field. However, these same portions are likely to beat in phase in even symmetry vibrations, and in this case, no sound is radiated in the far field. On the contrary, in the invention, we try to design the two areas so that, if one of them does not vibrate or little for some frequencies, the other takes over and vibrates to compensate for the lack of production sound of the first zone. Of course, it will be avoided that the two radiate in opposition of phase for a given frequency.
De préférence, la table d'harmonie 2 et le barrage 6 sont agencés pour installer dans la table d'harmonie, après tension des cordes, un état de contraintes statiques proche d'un état critique de flambement, de sorte que la table d'harmonie soit dans une configuration d'équilibre à la limite du flambement. Cette configuration favorise l'apparition de vibrations non-linéaires de la table d'harmonie, permettant un enrichissement du spectre sonore et donnant lieu à une dynamique plus vivante .  Preferably, the soundboard 2 and the dam 6 are arranged to install in the soundboard, after tension of the strings, a state of static stresses close to a critical state of buckling, so that the table of harmony in an equilibrium configuration at the limit of the buckling. This configuration promotes the appearance of non-linear vibrations of the soundboard, allowing an enrichment of the sound spectrum and giving rise to a more dynamic dynamic.
L'invention n'est pas limitée à ce qui vient d'être décrit, mais englobe au contraire toute variante entrant dans le cadre défini par les revendications.  The invention is not limited to what has just been described, but on the contrary covers any variant within the scope defined by the claims.
En particulier, bien qu'ici, les deux zones 2A, 2B sont de formes superposables mais sont rendues dissymétriques du point de vue de leur réponse fréquentielle par l'utilisation d'un barrage dissymétrique, toute autre disposition pourra être utilisée pour définir sur la table d'harmonie deux zones de comportement fréquentiels distincts. Par exemple, on pourra jouer sur les formes des zones pour en rendre l'une plus rigide que l'autre, on pourra prévoir des barrages adaptés optimisant leurs réponses fréquentielles , on pourra également jouer sur l'épaisseur de la table dans chacune des zones, c'est-à- dire en pratique utiliser des moyens de rigidification différentiels pour régler les comportements vibratoires des deux zones.  In particular, although here, the two zones 2A, 2B are of superimposable shapes but are rendered dissymmetrical from the point of view of their frequential response by the use of an asymmetrical dam, any other disposition can be used to define on the soundboard two distinct frequency behavior zones. For example, we can play on the shapes of the areas to make one more rigid than the other, we can provide adapted dams optimizing their frequency responses, we can also play on the thickness of the table in each of the zones that is to say in practice use differential stiffening means to adjust the vibratory behavior of the two zones.
Enfin, bien que l'on ait indiqué que l'on divisait la table d'harmonie en deux zones, on pourra bien sûr di- viser la table d' harmonie en plus de deux zones à comportements vibratoires complémentaires . Finally, although it has been said that we divide the soundboard into two zones, we can of course di- target the soundboard in addition to two zones with complementary vibratory behaviors.
