Description

DESCRIPCIÓNDESCRIPTION

Dispositivo resonador para guitarra y otros instrumentos musicales de cuerda.Resonator device for guitar and other string musical instruments.

Sector de la técnicaTechnical sector

La presente invención se refiere a un dispositivo resonador para guitarra o instrumentos musicales de cuerda que se aloja dentro de éstos y que multiplica el efecto resonador que de por sí produce el instrumento musical. Es un dispositivo resonador dentro de una cavidad resonadora que es el propio cuerpo del instrumento musical.The present invention relates to a resonator device for guitar or string musical instruments that is housed within them and that multiplies the resonator effect that the musical instrument itself produces. It is a resonator device within a resonator cavity that is the body of the musical instrument itself.

Estado de la técnicaState of the art

Son numerosos los dispositivos resonadores colocados internamente en guitarras e instrumentos de cuerda para producir un mayor volumen sonoro. La mayoría de ellos se suelen colocar debajo del puente y suelen ser metálicos como los que tienen las guitarras resonadoras o dobro. El tornavoz presente en las guitarras de Antonio de Torres es otro ejemplo de resonador que pretende aumentar el volumen sonoro del instrumento.There are numerous resonator devices placed internally on guitars and string instruments to produce a greater sound volume. Most of them are usually placed under the bridge and are usually metallic like those with the resonator or dobro guitars. The tornavoz present in the guitars of Antonio de Torres is another example of a resonator that aims to increase the sound volume of the instrument.

No obstante ninguno de estos resonadores ha sido lo suficientemente efectivo para ser incorporado de manera masiva a las guitarras e instrumentos musicales, exceptuando las guitarras resonadoras o dobro que se han convertido en un instrumento específico con unas características sonoras distintas y que han mantenido este tipo de resonador interno.However, none of these resonators has been sufficiently effective to be incorporated in a massive way to guitars and musical instruments, except for the resonator or dobro guitars that have become a specific instrument with different sound characteristics and that have maintained this type of internal resonator

El dispositivo aquí presentado pretende mejorar las deficiencias que presentan los dispositivos resonadores y añade características nuevas como aperturas en la caja del instrumento en zonas no aplicadas antes, una división del cuerpo de instrumento en dos zonas separadas e intercomunicadas por diversas aperturas y unos elementos suplementarios que aumentan la resonancia de ciertas frecuencias que al sumarse producen un aumento en la intensidad del sonido.The device presented here aims to improve the deficiencies of the resonator devices and adds new features such as openings in the instrument case in areas not previously applied, a division of the instrument body into two separate and intercommunicated areas by various openings and additional elements that they increase the resonance of certain frequencies that when added produce an increase in the intensity of the sound.

Descripción detallada de la invenciónDetailed description of the invention

La invención que aquí se presenta consta de una tapa interna que divide transversalmente la guitarra o instrumento musical en dos partes: la parte inferior en la que se encuentra el puente del instrumento y la parte superior del mismo donde se encuentran los demás elementos que comprenden el dispositivo resonador. Esta pared tiene unos orificios que comunican la parte inferior del instrumento con la superior.The invention presented here consists of an internal lid that transversely divides the guitar or musical instrument into two parts: the lower part in which the bridge of the instrument is located and the upper part of it where the other elements that comprise the resonator device This wall has holes that connect the bottom of the instrument with the top.

Es decir, se produce el sonido en la parte inferior del instrumento al poner el puente en movimiento la tapa del instrumento al transmitirle la vibración de las cuerdas. La pared separadora canaliza el sonido producido en la parte inferior convenientemente por esas aperturas para que pase de una manera controlada a la parte superior. En la parte superior se encuentran unas cajas acabadas en arista con aperturas que crean diversas reflexiones al circular ese sonido que procede de la parte inferior. Una apertura en el fondo del instrumento en la parte superior del instrumento contribuye a una circulación del sonido que está reflexionando continuamente y que sale por la boca de la guitarra o instrumento musical notablemente amplificado.That is, the sound is produced in the lower part of the instrument when the bridge of the instrument is set in motion when the vibration of the strings is transmitted. The separating wall channels the sound produced in the lower part conveniently through these openings so that it passes in a controlled manner to the upper part. In the upper part there are some boxes finished at the edge with openings that create different reflections when circulating that sound that comes from the bottom. An opening at the bottom of the instrument at the top of the instrument contributes to a circulation of sound that is continually reflecting and that comes out of the mouth of the guitar or musical instrument remarkably amplified.

Breve descripción de los dibujosBrief description of the drawings

Para la mejor comprensión de cuanto queda descrito en la presente memoria, se acompañan unos dibujos en los que, tan sólo a título de ejemplo, se representa un caso práctico de realización de un dispositivo resonador para guitarra y otros instrumentos musicales de cuerda. For the best understanding of what is described herein, some drawings are attached in which, just by way of example, a practical case of performing a resonator device for guitar and other string musical instruments is represented.

En dichos dibujos la figura 1 es una vista posterior del Interior del Instrumento en su parte superior, desprovisto de la tapa del fondo, en la que se aprecian los distintos elementos que componen la invención. La figura 2 es una vista también desde atrás del instrumento y sin la tapa del fondo más detallada de algunos elementos de la invención. La figura 3 es una vista frontal de la guitarra en la que desde el exterior del instrumento y a través de la boca se aprecian elementos de la invención. La figura 4 es una vista posterior del Instrumento desde el exterior donde se aprecian elementos de la invención. In said drawings, Figure 1 is a rear view of the Interior of the Instrument in its upper part, devoid of the bottom cover, in which the different elements that make up the invention are appreciated. Figure 2 is also a rear view of the instrument and without the more detailed bottom cover of some elements of the invention. Figure 3 is a front view of the guitar in which elements of the invention can be seen from outside the instrument and through the mouth. Figure 4 is a rear view of the Instrument from the outside where elements of the invention are appreciated.

Claims

1. Resonator device for guitar and other stringed musical instruments located internally in the upper body of the instrument, made of non-porous and flexible material that increases the loudness of the instrument by the sum of waves produced by the multiple reflection of certain frequencies that the device It causes inside and comprising: - a cover (1) with openings (2) that divides the instrument transversely and separates the lower part of the body from the instrument from the upper part.

- edge-finished projections that internally surround the upper body (3).

- a double cover that covers the cover and the bottom of the instrument in the upper area (4).

2. Internal resonator device for guitar and other stringed musical instruments according to claim 1 additionally made of a corrugated material.

3. Resonator device according to claim 1 which additionally comprises an opening in the bottom of the instrument (5).

4. Internal resonator device for guitar and other stringed musical instruments according to claim 1 wherein the openings (2) located in the cover separating the lower part of the upper part of the instrument comprise cylindrical tubes that extend towards said upper part (6).
