Description
La présente invention concerne un dispositif permettant l'amplification du son d'une guitare acoustique à cordes nylon ou métal, ou de tout autre instrument acoustique à cordes pincées ou frottées muni d'une caisse de résonnance, la particularité étant que le haut-parleur, le préampli, l'amplificateur et son alimentation ainsi qu'un système de réverbération numérique sont placés à l'intérieur du corps de l'instrument. The present invention relates to a device for amplifying the sound of an acoustic guitar with nylon or metal strings, or any other acoustic instrument with plucked or rubbed string provided with a sound box, the particularity being that the loudspeaker , the preamp, the amplifier and its power supply as well as a digital reverberation system are placed inside the body of the instrument.
L'amplification des guitares acoustiques est lo traditionnellement obtenue grace à un amplificateur extérieur à l'instrument. Ceci a pour conséquences plusieurs inconvénients l'obligation du transport d'un amplificateur en plus de la guitare (ce qui pose souvent un problème technique), l'obligation de relier la guitare à cet amplificateur par un cable assez peu ls pratique et disgracieux, enfin le fait que le son sortant de l'amplificateur et le son naturel de l'instrument ne viennent pas du même point dans l'espace. The amplification of acoustic guitars is lo traditionally obtained through an amplifier outside the instrument. This has the consequence of several inconveniences the obligation of carrying an amplifier in addition to the guitar (which often poses a technical problem), the obligation to connect the guitar to this amplifier by a cable somewhat impractical and unsightly, finally, the fact that the sound coming out of the amplifier and the natural sound of the instrument do not come from the same point in space.
Le dispositif selon cette invention permet de se libérer de ces contraintes. II comporte en effet selon une première 20 caractéristique un orifice situé dans l'éclisse basse de la guitare, au niveau duquel est fixée à l'intérieur de la guitare une minienceinte acoustique équipée d'un petit haut-parleur tourné vers l'extérieur. Invisible de l'extérieur, cette mini-enceinte est positionnée vers le 25 bas pour que le son amplifié ne soit pas dirigé directement vers l'instrumentiste, et ainsi se mélange au son acoustique de l'instrument avant d'arriver au musicien, bénéficiant de plus d'une diffusion dans la pièce avant d'arriver aux oreilles du musicien et des auditeurs. 30 L'emplacement de l'ouverture dans l'éclisse basse de la guitare permet également une certaine discrétion quant à l'esthétique de l'instrument. Une petite grille d'un aspect proche de la tonalité du bois de l'éclisse protège le haut-parleur. Le son de la guitare est capté par un micro piezzo situé dans le 35 chevalet, relié à un système préampli-amplificateur miniaturisé, également placé à l'intérieur de la caisse de la guitare. Cette amplification n'est pas prévue pour rivaliser en puissance avec les systèmes extérieurs existant, et rte doit pas ou peu dépasser la sonorité naturelle de l'instrument. The device according to this invention makes it possible to free oneself from these constraints. It comprises in fact according to a first characteristic 20 an orifice located in the lower splint of the guitar, at which is fixed to the inside of the guitar a minience acoustic equipped with a small speaker turned outward. Invisible from the outside, this mini-speaker is positioned towards the bottom so that the amplified sound is not directed directly to the instrumentalist, and thus mixes with the acoustic sound of the instrument before arriving at the musician, benefiting more of a diffusion in the room before reaching the ears of the musician and the listeners. The location of the opening in the bass splint of the guitar also allows some discretion as to the aesthetics of the instrument. A small grille with a look close to the wood tone of the splint protects the speaker. The sound of the guitar is picked up by a piezo microphone located in the bridge, connected to a miniaturized preamp-amplifier system, also placed inside the guitar body. This amplification is not intended to rival power with existing external systems, and must not exceed or exceed the natural sound of the instrument.
De plus, ce système interne inclut une réverbération numérique réglable donnant au son amplifié l'acoustique d'une pièce de plus ou moins grande dimension. La sonorité du jeu en direct est alors proche du son obtenu sur une platine de salon diffusant un enregistrement de guitare, et donne une amplitude supplémentaire à l'instrument en situation de récital. In addition, this internal system includes an adjustable digital reverb giving amplified sound the acoustics of a room of greater or lesser size. The sound of the live game is then close to the sound obtained on a living room deck broadcasting a guitar recording, and gives an additional amplitude to the instrument in a recital situation.
Le but de cette invention est de donner un soutien et un prolongement au son naturel de l'instrument, lui conférant une lo ampleur inégalée même par d'excellents instruments, tout en gardant un mélange harmonieux entre le son naturel de l'instrument et cette amplification modérée. La philosophie générale du système est d'obtenir au final une sensation de pur son acoustique. The purpose of this invention is to give support and extension to the natural sound of the instrument, giving it a breadth unparalleled even by excellent instruments, while keeping a harmonious blend between the natural sound of the instrument and this instrument. moderate amplification. The overall philosophy of the system is to ultimately get a feeling of pure acoustic sound.
15 Il est prévu selon le même principe une option à deux haut-parleurs pour un résultat stéréo, un deuxième micro type col de cygne étant alors placé au niveau de la rosace à l'intérieur de l'instrument. Le deuxième haut-parleur est alors placé de l'autre côté de l'éclisse basse de la guitare. Dans ce cas, la guitare est 20 équipée d'une réverbération numérique stéréo, pour donner plus d'espace au résultat sonore. According to the same principle, a two-speaker option is provided for a stereo result, a second gooseneck microphone then being placed at the rosette inside the instrument. The second speaker is then placed on the other side of the guitar's lower splint. In this case, the guitar is equipped with a stereo digital reverb, to give more space to the sound result.
Un accès facile par ouverture d'une trappe découpée dans l'éclisse haute permet l'accès à une batterie rechargeable alimentant le système. Les commandes volume, tonalité et 25 réglage de la réverb sont également placées sur l'éclisse haute de la guitare. Easy access by opening a hatch cut in the upper splint allows access to a rechargeable battery supplying the system. The volume, tone and reverb tuning controls are also placed on the high barbell of the guitar.
Selon des modes particuliers de réalisation et en fonction de choix esthétiques ou sonores différents, on pourra pratiquer les ouvertures à d'autres endroits de la caisse de l'instrument, pour 30 une diffusion du son amplifié et réverbéré dans d'autres directions. According to particular embodiments and according to different aesthetic or sound choices, it will be possible to practice the openings in other places of the instrument body, for an amplified sound diffusion and reverberated in other directions.
Ce dispositif concerne les guitares acoustiques, mais peut être adapté à tout autre instrument acoustique à cordes pincées ou frottées, muni d'une caisse de résonnance, comme par exemple 35 le luth et le oud. 2978286 Les dessins annexés illustrent l'invention This device relates to acoustic guitars, but can be adapted to any other acoustic instrument with plucked or rubbed strings, provided with a sound box, such as for example the lute and the oud.
