Definitions

  • the longitudinal profile of such small cross-sectional stiffeners has also proven to be an important influencing variable. In general, it improves the sound image if the cross-sectional height of the stiffening element in the longitudinal direction thereof extends from a first minimum value at one end to a maximum value or a plurality of relative maximum values to a second minimum value at the other end. This is plausible insofar as the stiffening effect decreases towards the ends of the elongated element, especially in the edge areas of the planar resonance element, so that the cross-sectional area is expediently reduced in comparison to the central sections.
  • FIG. 7 shows a violin bridge of conventional outline design, but with cross-sectional depressions ES on both flat sides of the bridge body.
  • the remaining thickness of the web body in the area between the depressions ES is greatly reduced in the manner shown in FIG. 7a, which means a corresponding saving in mass.
  • the depressions extend from the central height region of the web to the foot section, the upper boundary line G I of the depressions in the middle of the width approximately at half the web height and then running downward in an arc on both sides to the side edges of the web body.
  • This results in a border-like section of the web body which ensures the maintenance of sufficient bending stiffness in the middle and upper web area, but at the same time enables considerable mass savings in the area of the mutually parallel bottom surfaces of the depressions ES.
