    [0001]
    [0002]
    [0003]
    [0004] Field of the invention
    [0005]
    [0006] The present invention relates generally to stringed musical instruments. The present invention relates more particularly to a string instrument manufactured integrally from a solid block of non-wood rigid material, by computerized numerical control (CNC), obtaining an instrument that offers advantageous structural characteristics of simplicity and functionality
    [0007]
    [0008] State of the art
    [0009]
    [0010] Traditionally, string instruments have been constructed from wood, but they have also been made from other materials such as plastics, molded composite materials and combinations of such materials. These materials are imperfect and irreplicable for reasons inherent to their organicity and structure. Thus, they are easily deformable by exposure to use, temperature changes, erosion, structural stresses and, consequently, they are unable to offer a correct and permanent stability / reliability and to provide an adequate and equal sound over time or even among themselves. products of the same manufacturer and model giving rise to undesirable defects and tonal variations. These disadvantages have led to the use of alternative construction materials, such as metal materials.
    [0011]
    [0012] On the other hand, in many conventional string instruments, the various components are constructed separately, and then they are joined to form a finished instrument. Since the tonal quality depends to a large extent on the structural integrity of the instrument, there is inevitably some loss of quality due to the fact that several parts of the instrument, although permanently mounted, are actually separate pieces.
    [0013]
    [0014] From US Pat. No. 4359923 A it is known to construct a unitary guitar, formed from metal casting. Parts made from metal casting, in addition to resulting in inaccurate instruments, may suffer variations in density causing the sinusoidal wave that creates the vibration of the strings to be altered and affected by the material for which it is intended to propagate .
    [0015] In a stringed instrument like a guitar there are certain distances that are derived from pythagorean scales and highly accurate mathematical calculations that need to be replicated in order to obtain adequate adjustments, without which an instrument could never come to provide a sound Right. The advent of CNC machining has allowed the construction of high precision parts.
    [0016]
    [0017] Patents US 6233825 B1 and US 8829318 B1 describe metal guitar bodies manufactured by CNC.
    [0018]
    [0019] The diapason is a fundamental part for the operation of a string instrument, in conventional musical instruments the metal frets of the diapason are inserted individually in transverse grooves or channels configured on the front side of the diapason by friction-adjustment or additionally secured by glue. This is an expensive operation, which requires a high level of skill and experience on the part of a Luthier, becoming a tedious process of trial and error before reaching a satisfactory result. The touch of the diapason directly influences both the way of playing and the final sound of the instrument, becoming a very important and limiting aspect when choosing a musical instrument.
    [0020]
    [0021] US Pat. No. 8324489 B1 discloses a metal diapason made integrally and unitary by means of CNC.
    [0022]
    [0023] Exposition of the invention
    [0024]
    [0025] It is a principal object of the present invention to provide a novel and improved construction for a stringed musical instrument, such as a guitar, which has superior sound qualities by improving the hold of musical waves through it.
    [0026]
    [0027] It is another object to provide a high-precision string musical instrument that allows a substantially accurate duplication of instrument to instrument.
    [0028]
    [0029] It is an additional object to provide a stringed musical instrument that presents a significant reduction in production times.
    [0030]
    [0031] It is yet another object to provide an instrument provided with a diapason in which all the frets are integrally formed with said diapason and which is specifically designed to adapt to said instrument, being easily separable and replaceable by others of different radius, simple or compound (between its two extremes), and positioning of frets, which can also be dispensed with, giving the instrument great versatility.
    [0032]
    [0033] In order to achieve these objectives and avoid the drawbacks mentioned in the previous section, the present invention contemplates the construction of a stringed musical instrument in which all the main portions, including body, mast and spade are formed as an integral unitary structure , of non-wood rigid material, preferably aluminum. In addition, the instrument is provided with a plurality of cavities, housings and open chambers that reduce the total weight of the body while maintaining the required structural strength and by its configuration allow to control the resonance and sustain within the structure.
    [0034]
    [0035] The integral unitary structure of the instrument of the present invention is carried out by means of CNC from CAD / CAM designs, ensuring that the measures necessary for the correct operation of the instrument are calculated with an error tolerance of thousands.
    [0036] Characteristically, the diapason and the bridge are also CNC machined in a single metal piece, preferably stainless steel, offering the possibility of easily exchanging them and having tuning forks with different radii, simple or compound (between their two ends), and positioning of frets, which can also be dispensed with, for the same string instrument.
    [0037]
    [0038] The mast of the integral unitary structure of the instrument is equipped with a fixing system that allows easy disassembly of the diapason.
    [0039]
    [0040] With this invention, periodic revisions by a Luthier are not required since the design is based on a structure designed to withstand stresses much higher than those usually exposed and, its hardness / rigidity / elasticity coefficient, ensures a constant permanence of the necessary measures and adjustments of action between the body of the instrument and the points of support of the strings over time and use ensuring the non-deformation of the instrument itself and therefore the permanence of the initial adjustments.
    [0041] Therefore, the stringed instrument that is obtained results from very advantageous characteristics with respect to the conventional embodiments of stringed musical instruments that are known today.
    [0042] Brief description of the drawings
