Definitions

  • the invention relates to a method for producing the resonance body of string instruments, in particular a violin, and a device for forming the frames of the resonance body of string instruments, in particular a violin.
  • the known and generally used method for building a violin and other stringed instruments consists in the mere adaptation of all elements during their assembly, with the exception of gluing the bass beam to the ceiling, in which process prestresses are generated in the ceiling. Before gluing, the bass beam is bent in such a way that it adapts to the shape of the ceiling.
  • the correct shape of the frames is achieved by thermoforming them.
  • An outer or inner shape is usually used for molding. Such a fixed curvature of the frames and the edge strips ensures a tension-free state of the same before they are glued to the ceiling and floor.
  • a disadvantage of the known method is that the blanket made according to the conventional method absorbs the compressive force resulting from the tension of the strings. (W. Kaminski, J. Swirek “Lutnictwo” - PWM, Kraköw, 1972).
  • the quality of the instrument depends on the formant distribution in its spectrum. The closer the areas of the strongest formants are to 4,000 Hz, the better the instrument (S. Golechowski, N. Drobner-Akustyka muzyczna, PWN, 1953). A violin made according to the known method does not have this property and the areas of the strongest formants are below 3000 Hz.
  • the invention is therefore based on the object of specifying a method for producing the resonance body of a stringed instrument with which it is possible to shift the range of strong formants into the frequency interval from 3,000 to 4,000 Hz.
  • the goal is achieved through a new manufacturing process, which consists in introducing the prestressing into the resonance body in order to achieve the forces stretching the ceiling, which is to play the role of a membrane, as well as by using a new device for forming the frames.
  • the method according to the invention is characterized by the design of the top and bottom of the resonance body as outwardly curved plates with an edge profile curved for both in the same direction opposite to the bending tendency caused by the string elevator, by elastic deformation of the frames, gluing of the strips, deformation of the frames to to the final shape, glueing the frames to the ceiling, in which the bass beam was previously glued in in a known manner, by leveling its curved edge, and by closing the sound box by gluing the frames to the floor by leveling its curved edge.
  • the device for shaping the frames of the resonance body of string instruments consists of an oval ring with at least eight radially arranged holes, into which at least eight threaded sleeves are inserted, which receive pressure screws and correction screws.
  • An advantage of the method according to the invention is the formation of the resonance body with bias voltages which shift the region of the strongest formants towards higher frequencies, as a result of which the sound properties are improved. This results from the fact that formants of higher frequencies allow the emission of larger sound energies, which ensures a better load-bearing capacity of the instrument.
  • the frames can be given a shape while maintaining their elasticity, which makes it possible to achieve forces which stretch the resonance body along the main axis.
  • the drawing shows a view of a device for shaping the frames of the resonance body of string instruments, as can be used to carry out the method according to the invention.
  • the device consists of an oval ring 1 with eight threaded holes 2 together with threaded sleeves 3 for pressure screws 4, 5 and correction screws 6.
