Definitions

  • the invention relates to a device for transmitting string vibrations to the walls of a hollow body according to the preamble of claim 1.
  • the vibrations of the strings are radiated from those walls of the instrument body on which the bridge over which the strings are stretched stands.
  • This wall is usually called the ceiling.
  • the vibrations are transmitted through a so-called voice to the hollow body wall opposite the ceiling, the floor, and are also radiated from it.
  • the ceiling and floor are kept at a distance by frame walls and closed to form a hollow body.
  • the freedom of movement of the blanket is further restricted by a curvature of the blanket against the string tension. It necessarily stiffens the blanket in such a way that it is not pressed in by the string tension forces.
  • a further restriction on the freedom of movement of the ceiling is caused by the fact that string instruments transmit vibrations to the entire surface of the ceiling and support the string tension necessary so-called bass bar.
  • a further restriction of the freedom of movement of the ceiling and, above all, its size and the size of the instrument body cavity is created by the indentations next to the bridge, which are necessary for bowed instruments for the freedom of movement of the bow. In order to allow sufficient movement of the ceiling, the sound holes must be made between the indentations and the bridge.
  • the invention is therefore based on the object to provide an arrangement of walls and supports according to the preamble of the main claim, in which the string tension forces introduced via the web only insignificantly load the sound-radiating walls in the direction of their oscillating movement, the necessary stiffening the movements of these walls minimal impair and allow a large volume instrument body.
  • the tension forces of the strings stretched over the bridge are introduced perpendicular to the direction of movement of the sound-radiating walls of the instrument body, ie in the direction of the main plane of these walls.
  • these walls are not prestressed in the direction of oscillation movement and the amplitudes of the oscillations are not restricted.
  • These walls do not have to be arched for structural reasons. They can just be executed and then vibrate better to emit sounds.
  • There is also an arrangement of the radiating walls below the strings and the bridge which is an indentation of these Walls are unnecessary for the freedom of movement of the arch. Due to the statically more rigid derivation of the string tensioning forces, greater tensioning forces can be supported, the bridge can be made higher and the transmission ratio of the string oscillating movements to the movements of the sound-radiating walls can be increased.
  • the design of the supports according to claim 3 improves the transmission of the string oscillating movement initiated at the contact point of the bridge point-wise onto the contact wall to the entire surface of the large hollow body side walls, without the wide supports restricting the freedom of movement of the side walls.
  • the structure of the walls according to claim 4 reduces the moving masses.
  • the construction of the walls according to claims 5 and 6 has the same effect.
  • the notch in the footprint of the web improves the bending ability of this wall along the line mentioned.
  • the support wall is bent along this line. The lower the wall rigidity at this point, the less the transmission of the string movements is hindered.
  • Fig. 1 is a perspective view with a section through a stringed instrument hollow body at the point at which the arrangement of the components for transmitting the string oscillating movements on the hollow body walls is visible.
  • Fig. 2 is a side view of an instrument body according to the invention.
  • Fig. 3 shows a section through the instrument body at the level of the web.
  • Fig. 4 is a view of the instrument body on the footprint.
  • the bridge 1 shows a string 2 stretched over the bridge 1.
  • the bridge 1 stands with its feet 3 and 4 on the narrow hollow body wall 5.
  • On the side of the wall 5 facing away from the bridge there is between the base points 3 and 4 of the bridge 1, protruding from the web rising wall 5, the hollow body side wall 6.
  • triangular supports 7 and 8 run towards the surface of the wall 6 and touch them at the node 17.
  • Laterally outside of the foot points 3 and 4 there is another hollow body side wall 9 on the side of the footrest upright wall 5 facing away from the web Support 10 and touch it at position 18.
  • Each wall 6 and 9 has a straight side 22 and a curved side 23. They are kept at a distance on the straight side 22 by the web contact wall 5 and on the curved side 23 by the frame 11. At the corner points 24, which are formed by the walls 5, 6, 9 and 11, there is the tailpiece 12 on one side and the neck 13 on the other side.
  • the side walls each have a sound hole in the center for better sound radiation of the low tones.
  • a swinging movement of the side 2, for example in the direction of the arrow 30, causes the web 1 to move in such a way that the foot 3 presses in the wall 5 and the foot 4 lifts the wall 5.
  • the supports 7 and 10 are thereby pressed down and bulge the walls 6 and 9 in the direction of arrows 31 and 32 outwards.
  • the support 8 is raised by the upward movement of the base 4 and the wall 5 at this point and pulls the wall 6 in the same direction as the movement of the support 7 in the direction of arrow 32 outwards.
  • Fig. 2 shows an embodiment of the support 8 according to claim 3.
  • the support 8 is designed so wide that it extends to the corners 24, which from the walls 5,6,9 and 11th be formed. Its height decreases between the line of contact 15 with the web uprising wall 5 and the line of contact 21 with the wall 6, starting from the node 17 under the web 1 to the corners 24.
  • the movement of the support 8 is not only communicated at a point 17 of the wall 6, but also along the line 15 at which the support 8 touches the wall 6. This is no longer just bulged out like a tent, but something like an umbrella. In this case, a point load is distributed through the rods on the fabric surface.
  • the larger bulge of the wall 9 captures more air and produces a larger tone of the stringed instrument.
  • FIG. 3 A further embodiment of the string vibration transmission device is shown in FIG. 3 according to claim 6.
  • the transmission of the string vibrations to the walls 6 and 9 is improved by reducing the moving masses.
  • the moving masses are reduced here by omitting the parts of the walls 5, 6 and 9 listed in claim 6.
  • An improvement in the transmission of vibrations from the string 2 to the walls 6 and 9 consists in the wall 5, on which the bridge 1 stands, along the dashed lines 16 shown in FIG. 4, which originate from the base point 3 of the bridge 1, between the walls 6 and 9, and to the corners 24, which are formed by the walls 5, 6, 9 and 11, to make them more flexible by means of an indentation.
  • the wall 5 is bent along these lines.
  • the notch reduces the section modulus of the wall 5 at this point. The movements caused by the web 1 there are not already supported by a rigid wall 5, but are forwarded.
