Definitions

  • the present invention relates to stringed musical instruments, in particular amplified sound instruments such as so-called electric guitars.
  • - Half-body guitars are provided with a harmonization system consisting of a soundboard forming part of a resonance box.
  • This harmonization system aims, as in all classical string instruments, to create interactions between the vibrations of the different strings, thus causing substantial modifications to the timbre of the sounds emitted by each of them.
  • the invention aims to remedy the drawbacks of these two types of traditional electric guitars. It consists in integrating into a neck and full body of an electric guitar, a thin and flexible soundboard made of sound material, which is buckled under the effect of the tension of the strings of the instrument.
  • the soundboard allows you to recreate a harmonic mixture of strings while the absence of a sound box associated with the table avoids the LARSEN effect allowing the use of sound amplifiers of very high powers.
  • the instrument is designed to allow harmony tables of the same size but with different characteristics to be interchanged, thus giving the same instrument diversified harmonic characters by simply changing the table.
  • the soundboard is curved in shape and is in fixed support at one of its ends on the body of the instrument, while the strings are pushed at the other end by means of a tailpiece on which the strings hang.
  • the latter is substantially perpendicular to the strings and to the table and comes to bear, in its upper part on a fixed pivot and in its lower part on the free end of the table.
  • the tailpiece subjected to the tension of the strings therefore exerts an axial pressure on the soundboard, which causes it to buckle while ensuring its maintenance on the fixed support, the whole finding a balance when the strings are in tension .
  • the strings are attached to the tailpiece between the fixed pivot and its support on the table. According to one of the characteristics of the invention, the point of attachment of the strings can be moved along the tailpiece thus making it possible to adjust the effect of the rope on the table as desired. This result is obtained by attaching the rope to a member adapted to slide along the tailpiece between the two support lines thereof.
  • the body 1 of the instrument is made of solid material, preferably solid wood. It has in its middle a wide opening, for example a circular opening 2 on the edge of which a soundboard 3 rests under the strings 12 (FIGS. 1 and 2) which are conventionally mounted to the head, not shown, of the handle 9 of the instrument.
  • This thin and flexible soundboard is made of sound material and has a slightly curved shape, the convex face facing the strings.
  • the soundboard On the side of its support 8 on the body 1, the soundboard has over its entire width a substantially thicker flat rim matching the shape of the circular opening 2.
  • the electrical part i.e. sensors or classical type microphones, not shown in the drawings, sound recording for amplification being done under the strings, as in traditional electric guitars.
  • a tailpiece 4 which can be seen in more detail in FIGS. 2 and 3 comprises a series of slots 11, through which pass the strings which are locked by washers 10 on its rear face.
  • This tailpiece is freely supported by its upper part on the body 1 of the instrument by means of a metal bar 5 parallel to the bridge and fixed to the body.
  • the edge of this bar constitutes a fixed axis around which the tailpiece can freely pivot.
  • the tailpiece which extends in a plane substantially perpendicular to that of the soundboard 3 is supported, by its lower part, on the free end 13 thereof.
  • the shape of the tailpiece is such that the support plane of the washers 10 is substantially perpendicular to the strings, which prevents any accidental movement on their part on this part.
  • the position of the retaining washers 10 along the slots 11 it is possible to move the fulcrum of each of the strings on the tailpiece, between two limit positions located respectively in the vicinity of the bar. support 5, on the one hand, and the end 13 of the table, on the other hand,
  • the table being pinched between the tailpiece and the body of the instrument, is removable. To put it in place, it suffices to present its free end 13 on the tailpiece, the strings being relaxed, and to engage it on the support 8. To change the table, it suffices to loosen all the strings and when the pressure of the tailpiece becomes weak, a simple push of the finger on the table releases it from its supports.
  • the work of the table in the instrument according to the invention can be analyzed as follows.
  • the tension of the rope exerts traction on the tailpiece which, in turn, pushes on the free end of the curved and flexible table causing it to buckle; it therefore accumulates in the latter a certain amount of energy which counterbalances the tension of the rope and which depends on the adjustment of the rope on the tailpiece.
  • the variation in the traction exerted on the beating table results in a variation in the bending, and therefore in the radius of curvature thereof.
  • the variat, ions of the curvature of the table causing corresponding displacements of the position of the support edge 13, therefore oscillations of the tailpiece which are reflected simultaneously on the tension of all the strings; this interaction taking place in a relationship which is a function, for each rope, of the position chosen for its anchor point on the tailpiece.
  • Table 3 therefore constitutes for the electric guitar according to the invention, a harmonization system which, owing to the fact that it is not associated with a resonance box, is not subject to the LARSEN effect - due to the powers high amplifiers. sound cators.
  • the soundboard can be made of any sound and elastic material.
  • the curvature of the table (figure 2) is determined according to the elasticity of the material so that, when the tension of the strings is applied to the tailpiece, it is likely to store an energy which does not absorbs only a fraction of its elasticity potential, preferably just over half.
  • the invention applies to a bow instrument (violin, viola, cello).
  • a handle 20 carrying the classic button 21 is connected to a solid body 22, the outer line 23 of which follows the usual outline of the instrument, while the inner line 24 has a wide opening.
  • the height H (figure 4) of this body can remain significantly lower than that of the fishplate of a normal instrument.
  • a bottom 25 is glued over the entire underside of the body 22.
  • This body has an increase in thickness 26 at the connection of the handle and a part 27 projecting inwards to receive the accessories which will constitute a button 28 d 'attaches the tailpiece and possibly a spike (not shown) if it is a cello.
  • a series of several holes 32 is provided in the reinforcement 27 of the body to receive, as desired, the button 28 for attaching the tailpiece.
  • tailpiece 33 similar to that of the previous embodiment, except that its support means is constituted in this case by a flexible loop 34 of attachment passing over the button 28 and in a groove 35 formed in this effect near the top edge of the tailpiece.
  • the bridge 41 which supports the strings 36 rests here by one of its feet, or 42, on the table 38 itself, while its other foot 43 rests on a pillar 44 placed on the bottom 25 and made accessible by a window 45 provided for this purpose in table 38.
  • the bow instrument thus produced can in particular be used for work with considerably reduced sound levels.
  • the bow instruments thus designed can also lend themselves to their equipment with electronic amplification means while being sheltered from the drawbacks of the LARSEN effect.
  • the tailpiece 4A finds its fixed fulcrum 5A at its lower part, its exercise point 13A at the end of the table 3A is located above the previous one, while the tension of the strings 12A applies to the upper level 10A adjustable along the slots 11A.
