Definitions

  • the invention relates to a stringed instrument with a resonance body, the up through a ceiling and down is delimited by a curved or flat floor, whereby the ceiling carries a string supporting bridge and inside of the sound box at least one transverse to the direction of the strings extending lever and a support member are provided to together Vibration movements of the ceiling out of phase to transfer the ground.
  • US Pat. No. 5,542,329 is an instrument of this Kind known in which provided within the sound box Levers and support elements have the task of strings over the bridge acting on the ceiling of the sound box To transmit vibrations from it to its floor in such a way that this is an opposite or phase-shifted vibration movement executes.
  • This has the advantage that the on the Air in the resonance body has an inward pumping movement Ceiling due to the pumping movement that is directed inwards at the same time of the soil is supplemented.
  • the disadvantage is that the resonance body restricts its ability to vibrate Stiffening ribs are required to act on it via the web Absorb tension of the strings.
  • the invention has for its object a string instrument of the type mentioned, even if you keep one traditional outer shape of the sound box a fuller and has richer sound.
  • the ceiling of the Sound box without being overloaded by the resilience of the Strings with thin walls and thus more capable of vibration be and the bottom of the sound box a proportionate large vibration movement opposite to the vibration of the ceiling can execute.
  • this object is achieved by that the lever in the area of the web in at least two places abuts or is attached to the ceiling, of which a spot in the area below the tweeter string and the another is in the area below the bass string, that part of the lever is on the side of the tweeter string extends beyond the area of the web and on the sound box supports directly or via a support and that another part of the lever is also at right angles to Extending towards the strings, towards the ceiling supports curved arch, the support point between the two places where the lever is on the ceiling rests or is attached and with the two ends of the support arch up to the lateral edge area of the floor and extend there directly or in each case Support via a support part so that the support arch through the Force of the lever makes an elastic spreading movement.
  • the lever 6 On the inside of the ceiling 2 there is a lever (6) on two Locations, one of which is below the bass string 5 and the other is below tweeter string 4. In the area between these points the lever 6 lies on one support arch 8 curved upwards or towards the ceiling 2. Here is preferably at this support point between the two Spacer 19 is provided, the size of the size a bias between ceiling 2 and floor 11 and thus that Tone behavior of the instrument can be influenced.
  • the supporting arch 8 has the task of using its two ends 7 to exert a spreading force by its direct or indirect Action on the resonance body (3) a movement of the Soil 11 causes this movement of that of Blanket 2 is opposite or out of phase with this he follows.
  • the examples according to Fig.1 and 3 illustrate how the spreading movement of the support arch 8 from the solid Lines shown in the position shown by dashed lines 15 Position to an inward bend and thus Flatten the bottom 11. Because this movement through the simultaneous swinging inward movement of the Ceiling 2 is triggered, the sound box 3 according to Art of a bellows reduced according to the tone vibrations and enlarged.
  • the usual through string instruments Openings not shown in the ceiling 2 escaping air thus receives sound vibrations that are in harmony with those of the Vibration of the resonance body directed directly outwards Superimpose air vibrations or sound vibrations.
  • Fig.1 are based the ends 7 of the supporting arch 8 each in the corner area between the frame 10 and the bottom 11, so that the spreading movement of the supporting arch 8 to extend the curved bottom 11 leads.
  • the spreading movement presses of the support arch 8 the bowl-shaped rounded bottom 11 in its upper area outwards so that its lower one Area moved inward as shown by dashed lines 15 is.
  • the support arch 8 with its ends 7 over short Supports 9 in the corner area between the frame 10 and the floor 11 off so that he has one for arranging the flat inclined Connecting rods 13 has a sufficient distance from the floor 11.
  • the support takes place the ends 7 or the supports 9 according to Fig.2 preferably on a running in the longitudinal direction of the resonance body 3 Strip 12 so that the supporting forces in the longitudinal direction be distributed.
  • a longitudinal rib 18 the task of force distribution.
  • the support arch 8 and the floor 11 or the two attached to the floor Connecting rods 13 or the connecting bend 13 together delimit a shape called a rhombus can or comparable to the cross-sectional shape of a lens is, so that a spread to a flattening this shape and thus inward movement of the bottom 11 leads.
  • a spacer plate 14 may be provided, the Thickness can be selected to be similar to that using the spacer 19, the preload between the parts and thus to influence the sound behavior.
  • the fully drawn black Areas of the lever 6 correspond to its contact points in the Areas under the bass string 5 and the treble string 4.
