Figure 2 s The present invention relates to an electro-acoustic guitar resulting from the improvement and integration of the components of the patented instrument under the reference 83I2I28
I1 is characterized by a conceptual simplification of the body associated with a modular structure concerning three optional or removable equipment +++ A molded, compensated and adjustable key (4) +++ A traniductive bridge (5) structured along the front face of 1 instrument +++ An electronic system composed of an MC control module and a UB 6 electronic unit and placed in two boxes integrated into the internal structure (3)
The aesthetics and functionalism, the adaptation to injection molding and ultra-fast multiphase adhesives, make it a very efficient instrument in terms of quality / price.
Figure I shows the formal development of the object of this invention compared to the two market references +++ The model  of traditional invoice +++ The model B according to the Maman patent, molded with a curved bottom +++ The C HYPERFORKEL model presenting innovations in terms of the key (4), the internal structure (3), the organization of the electronic system associated with the new ohevalet-transducer (5) and functionalism (compound curvature CP, support for the right arm (AP), support plate (10).)
Figure 3 shows the structure of the second generation instrument according to patent n83I2128 (struotural assembly section As), with some improvements and adaptations for a very high-end invoice by Luthiers, with regard to the upper plate (3) and the counter-splint (section 1C)
Figure 4 represents the third generation structure. The internal structure (3) carries the reinforcement of the handle (6), the adjustment system (7) + (9) and integrates the end of the manohe, the electronic boxes (8) and the counter-fishplate whose section SA shows the special profile, the diction SB shows in section the composition at arm. The reinforcement (6), made from glass-polyester or carbon-epoxy pultruded laminate, is housed in the location located in the upper part of the internal structure (3). This situation makes it possible to withstand the bending-pressure pressures due to the tension of the strings.

Le système de réglage du manche (7)+(9) réalisé en acier inoxydable ou en titane permet de oorriger les déformations du manche . Ainsi réalisé ce dernier est trés rigide , procure un excellent sustain au son , la continuité structurale avec la caisse de résonance est intégralement assurée
La figure 5 montre la conception de la contre-éclisse (3) dont le profil est constitué de plots d'adhésion (3b) indépendants dans un mouvement de rotation autour d'un axe perpendiculaire à la table d'harmonie grâoe aux interstices (3a) .Ces plots d'adhésion permettent de coller la structure interne sur la table d'harmonie (2) en suivant exactement le profil de celle-ci .Le corps moulé (I) est collé sur une surface continue perpendiculaire à celle des plots tandis que un rebord (3c) assure la jonction esthétique entre la table d'harmonie et celui-ci
La figure 6 montre la liaison de la table d'harmonie et du corps qui est ainsi simplifiée et améliorée par rapport au système proposé par le brevet US NO 4213370 par exemple .Le raccord (3d) élastique permet une déformation longitudinale de la contre éclisse lors de l'assemblage pour rattraper les défauts de profil éventuels
Les boitiers (8) sont intégrés à la structure interne (3) , ils possèdent un rebord (8a) inférieur à l'épaisseur du corps (I); celui-ci étant élastique, peut s'enclencher sur oe rebord et suivre parfaitement le profil imposé par l'ensemble (2)+(3)+(6) au moment du montage
Les figures (7) , (8) , (9) et (IO) montrent un exemple de structuration interne correspondant à un moulage par injection . Sur la figure 7 apparaissent les trois zones Za , Zb et Zc correspondant au réglage de la touche avec les deux rainures permettant son alignement et les emplace ment s des vie de fixation
La figure 11 présente une caractéristique fondamentale et nouvelle de la touche (4) . Celle-ci est moulée en une seule pièce avec le sillet .Les vis (II) permettent de régler la hauteur des cordes graves ou bien aigus dans la sone Zc.On peut ainsi régler le jeu J entre les cordes et les frettes moulées (4a). Les vis (I2) permettent de fixer la touche sur le manche
La figure I2 définit trois zones distinotes t
Zb oorrespond à la fixation de la touche , par l'intermédiaire de quatre vis . Zc correspond au réglage du sillet .Za correspond à la compensation de la position des frettes (4a) par rapport au noeud de vibration de la note fondamentale jouée . En effet si on considère la hauteur du sillet R Dorrespondant au diapason D et les points SI sFQ ,B3 E4 correspondant successivement aux distances 3D/2 , D/2 , et D/4 lorsque le musicien appuie sur la corde (I3) pour jouer une note ç on remarque que la distance séparant le milieu de la corde vibrante li de la touche (4) reste constante alors qu'elle devrait décroitre proportionnellement à la longueur utile de celle-ci en raison de l'amplitude décroissante des ventres de vibration
I1 convient donc de compenser cette distance en relevant la zone Za de la touche par l'intermédiaire de la vis (lia) principalement pour les cordes aiguës , le même réglage pouvant se faire pour les cordes graves mais celui-ci nsest pas justifié en raison de la rareté d'utilisation des sonorités graves dans cette zone de la touche
La figure (I3) montre un exemple de conception d'une telle touche avec son sillet (4c) , ses vis de fixation (12) et ses vis de réglage (11) et (lia)
La figure 14 montre l'emplacement des rainures (4b) guidant les cordes et assurant un jeu minimal Jb
La figure I5 montre les nervures de positionnement (4e) et un logement (4d) permettant de placer un profilé composite augmentant l'élasticité de la touche
La figure I6 montre comment obtenir un profil techniquement efficace des barrettes moulées (4a) . Les touches des guitares "BONV' présentent un profil moulé suivant la figure I7 .Ce profil présente une nette amélioration du point de vue ergonomique . Cependant il s'avère lourd au toucher et manque de précision en ce qui concerne le positionnement dynamique des doigts sur les frettes .Afin d'obtenir un profil plus performant les barrettes sont réalisées par un plan en dépouille (4a) et l'espace séparant celles-ci est constitué de deux zones X (4g) plane et (4f) courbe ( circulaire , parabolique ou hyperbolique ) . Ainsi la sensation kinésique entre les doigts des musiciens et la touche est plus précise ,plus agréable et plus efficace que sur une succession de gradins
Une autre modification fondamentale concerne le chevalet-transduoteur(5).
The handle adjustment system (7) + (9) made of stainless steel or titanium allows to correct the deformations of the handle. Thus realized the latter is very rigid, provides excellent sustain to the sound, structural continuity with the sound box is fully ensured
FIG. 5 shows the design of the counter-fishplate (3), the profile of which is made up of independent adhesion pads (3b) in a rotational movement around an axis perpendicular to the soundboard thanks to the interstices (3a These adhesion pads allow the internal structure to be bonded to the soundboard (2) by exactly following its profile. The molded body (I) is bonded to a continuous surface perpendicular to that of the pads while that a rim (3c) ensures the aesthetic junction between the soundboard and the latter
Figure 6 shows the connection of the soundboard and the body which is thus simplified and improved compared to the system proposed by US patent NO 4213370 for example. The elastic connection (3d) allows a longitudinal deformation of the back plate during of the assembly to make up for any profile defects
The boxes (8) are integrated into the internal structure (3), they have a flange (8a) less than the thickness of the body (I); the latter being elastic, can snap onto the edge and perfectly follow the profile imposed by the assembly (2) + (3) + (6) at the time of assembly
Figures (7), (8), (9) and (IO) show an example of internal structure corresponding to an injection molding. In Figure 7 appear the three zones Za, Zb and Zc corresponding to the adjustment of the key with the two grooves allowing its alignment and the locations of the fixing lives
FIG. 11 presents a fundamental and new characteristic of the key (4). This is molded in one piece with the nut. The screws (II) allow you to adjust the height of the bass or treble strings in the Zc sone. You can thus adjust the clearance J between the strings and the molded frets (4a ). The screws (I2) allow to fix the key on the handle
Figure I2 defines three distinguished areas t
Zb corresponds to the fixing of the button, by means of four screws. Zc corresponds to the setting of the nut. Za corresponds to the compensation of the position of the frets (4a) relative to the vibration node of the fundamental note played. Indeed if we consider the height of the nut R Corresponding to the tuning fork D and the points SI sFQ, B3 E4 corresponding successively to the distances 3D / 2, D / 2, and D / 4 when the musician presses on the string (I3) to play a note ç we note that the distance separating the middle of the vibrating cord li of the key (4) remains constant whereas it should decrease in proportion to the useful length of this one because of the decreasing amplitude of the vibration bellies
It is therefore advisable to compensate for this distance by raising the zone Za of the key via the screw (IIa) mainly for the treble strings, the same adjustment being able to be made for the bass strings but this is not justified because the rarity of using bass tones in this area of the button
Figure (I3) shows an example of the design of such a key with its nut (4c), its fixing screws (12) and its adjustment screws (11) and (lia)
Figure 14 shows the location of the grooves (4b) guiding the strings and ensuring minimal play Jb
Figure I5 shows the positioning ribs (4e) and a housing (4d) for placing a composite profile increasing the elasticity of the key
Figure 16 shows how to obtain a technically efficient profile of the molded bars (4a). The keys of the "BONV 'guitars have a molded profile according to figure I7. This profile presents a clear improvement from an ergonomic point of view. However, it turns out to be heavy to the touch and lacks precision with regard to the dynamic positioning of the fingers on The frets. In order to obtain a more efficient profile, the bars are produced by a draft plane (4a) and the space separating them consists of two flat X (4g) and curved (4f) zones (circular, parabolic or hyperbolic). So the kinesic feeling between the musicians' fingers and the key is more precise, more pleasant and more effective than on a succession of steps
Another fundamental modification concerns the bridge-transducer (5).

La figure I8 montre un chevalet de conception traditionnelle - collé sur la table d'h3rsonie . Le transducteur est constitué par des pastilles piezo-électriques (19) - les vibrations des cordes (I3) sont transmises par le sillet (50). Du fait de l'étroitesse de la rainure de positionnement ,la convection électrique (20) est particulièrement difficile à réaliser . De plus le sillet tend b basouler dans son logement et le transducteur fonctionne dans de mauvaises conditions
La figure (I9) montre un chevalet conçu selon l'invention .Celui-ci est démontable et fixé sur la table d'harmonie par des vis (I4) . I1 est supporté par une cale (I6) d'épaisseur variable . L'accrochage des cordes se fait par l'intermédiaire d'une plaque métallique (I5) qui permet en plus la mise à la masse afin d'éliminer les parasites induits par l'élec- tricité statique ( effet de main ) . Une nouveauté structurale concerne le système de transmission des vibrations mécaniques des cordes vers le transducteur (I7) par l'intermédiaire de plots individuels (5c) déformables dans la zone (5a) .La transmission des signaux électriques se fait par un branchement (I7a) .
Figure I8 shows a easel of traditional design - glued to the hsoncraft table. The transducer is made up of piezoelectric pads (19) - the vibrations of the strings (I3) are transmitted by the saddle (50). Due to the narrowness of the positioning groove, electrical convection (20) is particularly difficult to achieve. In addition, the nut tends to roll in its housing and the transducer works in poor conditions
The figure (I9) shows an easel designed according to the invention. It is removable and fixed on the soundboard by screws (I4). I1 is supported by a shim (I6) of variable thickness. The strings are hooked via a metal plate (I5) which also allows grounding to eliminate parasites induced by static electricity (hand effect). A structural novelty concerns the system for transmitting mechanical vibrations from the strings to the transducer (I7) by means of individual studs (5c) which can be deformed in the area (5a). The transmission of electrical signals is via a connection (I7a) .

La figure 20 montre l'action mécanique des cordes (I3) sur le transducteur (I7) . Celui-ci peut comporter une languette d'accrochage facilitant son interchangeabilité . Une pièce d'usure (I8) peut être interposée sur les plots (5c) . La table d'harmonie (2) est renforcée par une plaque (2a) autorisant la fixation du chevalet par vissage . Un contacteur (17b) est disposé sur la plaque-support pour venir en correspondance avec les contacts (I7a) du transducteur
La figure 2I montre un exemple de réalisation d'un transducteur capable de siintégrer au chevalet afin de constituer un tout fonctionnel .Les signaux électriques sont générés par six éléments de film piézo-électrique de 40 microns d'épaisseur environ , repère (I9) .Ces signaux sont collectés par un circuit (20) .Ce dernier est réalisé par deux oonstituants distincts t une plaque de circuit imprimé (22) comportant les contacts (I7a) recouvert de vernis isolant sauf dans les régions (23)
+++ une plaque (21) constituée de lames conductrices transversales alternées aves des lames isolantes (2nô) assure le couplage des faces supérieures des éléments piezo-éleotriques (I9) aveo les zones non isolées (23) .Ce type de connection est couramment utilisé en électronique
La figure 22 montre le principe d'assemblage du corps de l'instrument de troisième génération s
PHASE I t Un plan P sert de référence ; sur la table d'harmonie (2) disposée à plat est collé le barrage (2a)g le renfort (6) est lui aussi disposé et orienté sur P
PHASE 2 s La structure interne (3) avec la oontre-éclisse et les boitiers électroniques 1 est pressée et collée sur la table d'harmonie en oême temps que le renfort (6) .Des gabarits de profil pissés latéralement assurent la bonne disposition de la contre-éclisse
PHASE 3 s Le système de réglage (7)+(9) est disposé dans la rainure correspondante de la structure interne (3).
Figure 20 shows the mechanical action of the strings (I3) on the transducer (I7). This may include a hooking tab facilitating its interchangeability. A wearing part (I8) can be interposed on the studs (5c). The soundboard (2) is reinforced by a plate (2a) allowing the bridge to be fixed by screwing. A contactor (17b) is arranged on the support plate to come into correspondence with the contacts (I7a) of the transducer
FIG. 2I shows an exemplary embodiment of a transducer capable of integrating into the bridge in order to constitute a functional whole. The electrical signals are generated by six elements of piezoelectric film of approximately 40 microns thick, reference (I9). These signals are collected by a circuit (20), which is produced by two separate components: a printed circuit board (22) comprising the contacts (I7a) covered with insulating varnish except in the regions (23).
+++ a plate (21) made up of alternating transverse conductive strips with insulating strips (2nô) ensures the coupling of the upper faces of the piezoelectric elements (I9) with the non-insulated areas (23). This type of connection is commonly used in electronics
Figure 22 shows the principle of assembly of the body of the third generation instrument s
PHASE I t A plane P serves as a reference; on the soundboard (2) placed flat is stuck the barrier (2a) g the reinforcement (6) is also arranged and oriented on P
PHASE 2 s The internal structure (3) with the counter-splice and the electronic boxes 1 is pressed and glued to the soundboard at the same time as the reinforcement (6). Side-pissed profile templates ensure the correct arrangement of backstop
PHASE 3 s The adjustment system (7) + (9) is arranged in the corresponding groove of the internal structure (3).

PHASE 4 : Aprés enduction avec un adhésif, le corps (I) , moulé sous épaisseur constante et déformable , est appliqué sur le sous-ensemble précédent
En utilisant des adhésifs multiphases ultra-rapides le montage du corps peut être automatisé et assuré en quelques dizaines de secondes . Celui-ci peut alors outre traité en finition puis équipé de ses accessoires
La fabrication et le montage sont plus rapides et plus rationnels
A l'inverse des guitares acoustiques de facture traditionnelle auquelles on surajoute un micro et un préamplificateur , la guitare électro-acoustique intégrale forme un tout structural avec le transducteur et le système électronique
PHASE 4: After coating with an adhesive, the body (I), molded under constant and deformable thickness, is applied to the previous sub-assembly
By using ultra-fast multiphase adhesives, the mounting of the body can be automated and ensured in a few tens of seconds. This can then be further processed and then equipped with its accessories
Manufacturing and assembly are faster and more efficient
Unlike traditional acoustic guitars to which we add a microphone and a preamplifier, the integral electro-acoustic guitar forms a structural whole with the transducer and the electronic system.
