Definitions

  • the present invention relates to a string tensioner for a fine tuning device of a string instrument.
  • the invention further relates to a fine tuner screw for a fine tuner of a string instrument and a tailpiece for a string instrument.
  • Fine tuning devices are used to more easily and cleanly tune a string of a string instrument, such as a violin, a viola, a cello, or a double bass.
  • a fine tuning device is known to include a string tensioner and a fine tuner screw and is arranged on a tailpiece.
  • Such a fine-tuning device can be provided for each string of the string instrument, or such fine-tuning devices are only provided on the tailpiece for certain strings.
  • a string of the instrument is held by the fine tuning device and the string tensioner is moved by operating the fine tuner screw. This movement puts more or less tension on the instrument's string, which affects the tuned pitch.
  • the sound is produced by causing a string to vibrate with a bow or a finger, and this vibration is transmitted to the instrument (particularly the body).
  • the properties of a string instrument are determined in particular by its playability, i.e. how well a sound can be produced, and determines the sound of the instrument. Consequently, it is a constant effort to continually improve the playability and sound production of string instruments.
  • An object of the invention is to provide a string tensioner, a fine tuner screw for one or more selected strings, and a tailpiece, each of which improves the playability and sound production of a string instrument.
  • a string tensioner for a fine tuning device of a string instrument having a substantially L-shaped construction with a longitudinal arm and a transverse arm, the longitudinal arm being longer than the transverse arm.
  • the cross arm includes a receiving device for a string of the string instrument.
  • a height of the longitudinal arm outside a corner region of the string tensioner corresponds to at least 15% of a length of the longitudinal arm at a highest point.
  • the string tensioner is made of at least 75% brass material.
  • One advantage here is that such a string tensioner improves both the playability and the tone produced by a string instrument. This is the case because brass has both beneficial properties for sound production (a higher density than commonly used materials) has, as well as the relatively large height of the longitudinal arm creates a large-volume shape of the string tensioner. Brass is heavier compared to the materials commonly used in this context (plastic, aluminum, titanium) and, unlike the usual materials, vibrates in a musically advantageous manner. The high proportion of brass material used here of at least 75% leads to a particularly advantageous vibration behavior of the string tensioner.
  • the string tensioner is advantageously made of solid brass. This also reduces or avoids disruptive vibration bridges.
  • the area of the instrument string below a bridge over which the strings are guided is calmed by the heavy weight of the string tensioner.
  • the bridge is therefore caused to vibrate primarily by deflecting the string using the bow or finger. Passive, disruptive vibrations of a tailpiece decrease. This leads to an improved feel of the instrument and an improvement in the sound.
  • the response of the strings becomes easier and faster. At the same time, the strings can withstand more pressure from the bow when playing. This gives the musician more options to model the sound of the instrument.
  • the string tensioner described here gives the overall sound of the instrument more volume, transparency and more bass on the low strings.
  • the essentially L-shaped design is characterized in that the string tensioner has a longitudinal arm and has a cross arm, which are connected to one another in a corner area or merge into one another.
  • the string tensioner is, for example, designed in one piece.
  • the height of the longitudinal arm outside the corner area here describes the extent of the longitudinal arm in a main direction of extension of the transverse arm, i.e. in a direction perpendicular to a main direction of extension of the longitudinal arm itself.
  • This height is at least 15% of a total length of the longitudinal arm.
  • the height can also be at least 20% or 25% of the total length of the longitudinal arm. This leads to even larger volume string tensioners, which further increases the weight of the string tensioner, further contributing to the improved playability and sound.
  • a width of the longitudinal arm outside the corner region of the string tensioner at a widest point corresponds to at least 10% of a length of the longitudinal arm.
  • the width is at least 15%.
  • the string tensioner is made entirely of a brass material.
  • One advantage here is that an uncomplicated manufacturing process is possible with a string tensioner made from just one material.
  • a String tensioner in particular have good playability and good sound properties, since - as described above - brass has a beneficial effect on these properties.
  • the string tensioner has at least one recess or four homogeneous surfaces on the longitudinal arm.
  • Such a recess can be one or more through-holes in the longitudinal arm, or one or more millings in the longitudinal arm.
  • An advantage of homogeneous surfaces i.e. with a string tensioner without recesses, is that a high weight and a homogeneous material flow of the brass material is achieved by the string tensioner, which has an additional positive influence on playability and sound production.
  • a surface of the longitudinal arm facing away from the transverse arm has a convex surface structure and/or a surface of the longitudinal arm facing the transverse arm has an at least partially concave or convex surface structure.
  • the convex surface provides additional mass on the string tensioner, which further improves playability and sound production.
  • such a string tensioner can be advantageously inserted into a tailpiece.
  • the string tensioner has a bulge on the longitudinal arm, on an end region of the longitudinal arm facing away from the corner region, and on a surface of the longitudinal arm facing away from the transverse arm.
  • One advantage here is that additional mass is introduced into the string tensioner in the end region of the longitudinal arm.
  • a fine tuner screw hits the string tensioner.
  • the mass is increased, which additionally causes vibrations in the Fine tuning device calms down.
  • the string tensioner has a hole in the corner region in which the longitudinal arm is connected to the transverse arm, which is suitable for receiving a fastening axis of a tailpiece.
  • a fine tuner screw for a fine tuner of a string instrument comprises an external thread which is designed to be screwed into an internal thread of a tailpiece.
  • the fine tuner screw is made of at least 75% brass material.
  • the fine tuner screw further comprises a knurled head, each of which has a height and a width of at least three times a diameter of the external thread of the fine tuner screw.
  • the advantages of the fine tuner screw specified here essentially correspond to those of the string tensioner described in detail above.
  • the choice of material and the large-volume design of the fine tuner screw calm vibrations in a tailpiece in which the fine tuner screw is inserted, as well as in the interaction between a string tensioner and fine tuner screw, and improve the playability and sound production of an instrument in which such a fine tuner screw is installed .
  • this is Fine tuner screw made entirely of brass material.
  • the fine tuner screw is advantageously made of solid brass. This also reduces or avoids disruptive vibration bridges.
  • a tailpiece for a string instrument wherein the tailpiece is made of at least 75% of a brass material.

  • the tailpiece is made entirely of a brass material.
  • One advantage here is that an uncomplicated manufacturing process is possible.

  • the mounting axle is also made of at least 75% brass material, the playability and sound production are further improved.
  • the vibrations are spread more evenly across all components and all existing string tensioners distributed. Vibration bridges, i.e. different speeds and intensities of sound transmission and reflections due to differences in materials, are avoided or at least reduced.
  • the tailpiece and/or the fastening axle is made entirely of a brass material.
  • a brass with the EN material number CW 614N also known as CuZn39Pb3 or MS58
  • the DIN material number for this brass alloy is 2.0401.
  • Advantages of this alloy are, for example, that it has high strength but at the same time good machinability, which facilitates the production of the brass components described here.

  • the height HL at the highest point of the longitudinal arm 2 is at least approximately 6.195 mm.
