Definitions

  • the invention relates to a stringed instrument, for example, a violin, a lyre or a harp comprising a frame, a lower plate glued to said frame, a top plate glued to said frame, said frame together with said plates bounding a sound box and comprising a fastening part extending outside said sound box and into said sound box and provided with string fastening members, which may be adjustable, a second fastening part arranged on the side remote from the first fastening part on the frame and/or the top plate and provided with string fastening members, strings stretching between the fastening members of the two fastening members across the sound box and means for transmitting the vibrations of the strings to the top plate and/or the lower plate.
  • a stringed instrument for example, a violin, a lyre or a harp comprising a frame, a lower plate glued to said frame, a top plate glued to said frame, said frame together with said plates bounding a sound box and comprising a fastening part
  • the invention relates in particular to a method of manufacturing such instruments.
  • a flute comprises, as is known, a head or mouthp-ece and an adjoining resonance tube.
  • the tone formation takes place in the mouthpiece in which whirls are produced. If there were no resonance tube, these whirls would become manifest as an audible tone or as a noise in which not any tone predominates. Only in the presence of the resonance tube a given tone can be amplified to an extent such that it becomes virtually sonorous.
  • the transitional area may also be termed a tone-forming region under the name of consonance.
  • tone-forming elements are the strings, the bridge (the transversal tension of the strings) and the top plate, whilst the resonance elements are: the sides of the bottom plate, the bass beam below the top plate (longitudinal tension of the strings) and the column.
  • the meeting region between the tone formation and the resonance, the consonance region, is formed by two members which, so to say, "mediate” between the two types of tension transmission to the sound body (resonance body). These members join the longitudinal tension to the transverse tension.
  • the longitudinal tension of the string is brought into contact with the resonance space by the round bass beam to be described hereinbelow, which begins where the column enters the resonance space. This round bass beam spreads on the periphery of the bottom plate.
  • the transverse tension of the string is brought into contact with the resonance space by the so-called vaulted bass beam which supports the top plate in the plane of the bridge and establishes a connection with the bottom plate.
  • the transverse tension and the longitudinal tension meet in the open resonance space.
  • a method as described in the preamble in which method first a first glue layer is applied between the bottom plate or the top plate and the frame, the plate concerned and the frame are brought into contact with one another through said first glue layer and the first glue layer is cured, after which or in addition a second glue layer is applied between the other plate and the frame, whilst leaving free the transition zone between the first fastening part of the sound space, the plate concerned and the frame being brought into contact with one another through the second glue layer, which is cured, the strings being subsequently mounted and stretched, whilst finally at the area of said transition zone a mass of glue is applied and allowed to cure.
  • the first and the second glue layers and the mass of glue can be allowed to cure during a period of the order of one day.
  • an embodiment may be used in which the frame is at least partly laminated.
  • the virtual formation of the consonance takes place in a preferred embodiment to be discussed later by means of two particular members, one of which has a definite form character, the other a distinct movement character.
  • the column enters the resonance space, it gets separated from the top plate and the bottom plate and extends over a short distance, so to say, freely in the space.
  • This free zone of movement is particularly important for the manner in which consonation takes place. Small and even minute variations have a great influence on the interengagement of the longitudinal and transverse tensions and hence on the tone formation and the resonance.
  • the zone concerned is termed in the instrument construction the zero point.
  • the second particular member is formed by the foot to be described later.
  • This foot has a laminated structure and serves to directly transmit the longitudinal tension of the column to the top side of the bottom plate and simultaneously, owing to the relationship to the laminated parts of the frame to be described hereinafter, including the column, to the sides of the resonance space.
  • Fig. 1 shows a lyre 1 comprising a frame 2, part of which is formed by a column 3.
  • the column 3 forms part of a bracket 4 extending outside the resonance space 5, which is bounded on one side by the frame 2 and on the other side by a bottom plate 6 and a top plate 7.
  • strings 8 Between the resonance space 5 are stretched strings 8 between fastening members 9 constructed in the form of tensioners and an apertured fastening beam 10. The strings 8 are stretched across a bridge 11 arranged on the top plate 5.
  • the top plate 7 has a sound hole 12.
  • Fig. 2 shows a harp 13 comprising a frame 14, part of which is formed by a column 15. This column forms part of a bracket 16 extending outside the resonance space 17.
  • the resonance space is bounded on the one side by the frame 14 and on the other side by a bottom plate 18 and a top plate 19. Across the resonance space 17 are stretched the springs 20. One end thereof is fastened to tensioners 21 arranged on the bracket 16 and the other end is fastened to a bridge 22 secured to the top plate 19.
  • the lyre 1 has a fastening beam 10 and a separate bridge 11. In the case of the harp 13 the bridge is at the same time a fastning member for the strings.
  • the top plate 19 has furthermore sound holes 23, 24, 54, 55.
  • Fig. 3 shows a violin 25. It comprises a frame 26, part of which is formed by a neck 27.
  • the frame 26 together with a bottom plate 28 and a top plate 29 bounds a resonance space 30, across which strings 31 are stretched.
  • One end thereof is fastened to tensioners 32 at the end of the neck 27 and the other end is fastened to a fastening member 33 connected with the frame 26.
  • the top plate 29 has sound holes 34, 35.
  • the strings 31 are stretched across a bridge 36, which is carried by bridge feet 37, 38, which extend downwards through holes 39, 40 in the top plate 29 and are coupled through bass beams to be described with reference to Fig. 8 with the bottom plate 28.
  • Fig. 4 shows the lyre 1 of Fig. 1 during the manufacture thereof. This Figure clearly shows the internal structure.
  • the column 3 is ramified in the transition zone designated by reference numeral 41 to the resonance space 5 into four separate parts, to wit a laminated wall part 42, the round bass beam 43 glued to the bottom plate 6, the laminated foot 44 locally glued to the bottom plate 6 and a laminated frame beam 45.
  • the vaulted bass beam 46 which is locally glued to the bottom plate 6 and fully glued to the top plate after manufacture.
  • Fig. 4 shows in broken lines the surfaces which are first provided with glue for fastening the top plate 7 during the manufacture of the lyre 1.
  • the transition zone 41 as is shown, is not provided with a layer of glue during this stage of manufacture.
  • Reference numeral 47 designates means for exerting a bias stress in the direction of the strings 8 to be stretched afterwards and applying bending stress during curing of the layers of glue between the frame 2 and the bottom plate 6 and the top plate 7.
  • a pressing stamp 48 is used for pressing tight the top plate.
  • Fig. 5 shows a detail of the lyre 1 of Fig. 4 in a further production stage.
  • glue is applied to the transition zone 41 corresponding to the above-mentioned zero point.
  • a tube of glue 49 and a spatula 50 are shown schematically.
  • Figs. 4 and.5 illustrate the manner in which the laminated foot 44 and the laminated frame beam 45 are glued to the column 3 in the transition zone 41.
  • the laminated wall part 42 extends throughout the length of the column.
  • Fig. 6 shows the harp 13 in a production stage.

  • Fig. 6 shows the internal structure of the harp 13.
  • the column 15 adjoins a round bass beam 57, which is glued to the bottom plate 18.
  • a vaulted bass beam 58 There is furthermore provided a vaulted bass beam 58.
  • the harp 13 does not comprise an internal, laminated part.
  • a bending force is exerted by bending means 59 on the curing structure in the manufacture of the harp 13.
  • the top plate 19 is pressed tight by means of a pressing stamp 60.
  • Fig. 7 shows the next-following production stage in which the transition zone is provided with glue.
  • a spatula 61 with glue 62 is schematically shown.
  • a corner part 63 is glued between the column 15 and the adjacent surface of the frame 14. This corner part completes the desired coupling between tone formation and resonance, that is to say, it is co-determinative for the desired consonance.
  • a stock of glue 64 and a glue brush 65 are schematically shown.
  • Fig. 8 shows the violin 25 during a manufacturing stage.
  • the internal structure of the violin 25 is clearly shown in Fig. 8.
  • the neck 27 is divided in the resonance space into a first bass beam 66 to be glued to the bottom plate 28 and a second bass beam 67 to be glued to the top plate 29.
  • the bridge feet 37 and 38 are connected with the first bass beam 66 and the second bass beam 67 respectively.
  • the bridge foot 37 is carried by a stem 68 carrying a forkshaped member formed by two curved stack parts 69 and 70.
  • the stack part 69 is connected with the first bass beam 66 near the end thereof, whereas the stack part 70 is connected with the second bass beam 67.
  • transition zone between the neck 27 and the resonance space 30, more particularly, the end of the first bass beam 66 facing the neck 27 is not provided with glue.

  • the harp does not comprise internal, laminated parts like the lyre.
  • the lamination in this case is not needed because the much larger surface of the side allows a more favourable mass ratio than in the lyre.
  • the side at the column has sufficient form stability owing to the large surface. In the lyre it is necessary to strengthen this form stability.
  • the essential difference between the harp and the lyre is discussed above, i.e. the presence of a fastening beam and a separate bridge in the lyre and a combined function in the harp.
  • the transverse tension (also termed the tone forming tension) of the strings is brought into contact with the space of the resonance bocy, whereas in the harp the longitudinal tension (also termed the space tension or resonance tension) is brought into contact with the mass of the resonance body.
