BE1019457A5 - ANTI-BEARING FOR CELLOS, ALTOS AND VIOLINS. - Google Patents

Abstract

Accessory for stringed instrument to be fixed on one of the strings, on the part located between the bridge and the tailpiece and allowing to eliminate the rolling resulting from a conflict of sound frequencies, also called the "wolf", characterized in that thanks to its "U" shape and its silver composition it enriches the tone of the instrument and optimizes the reduction of the roll by tuning the sound frequency emitted by the part of the string located between the bridge and the tailpiece of the instrument with the sound frequency of the rolling note.

Description

Anti-roll for cellos, violas and violins

Problem to solve

The wolf, or rolling is the result of a conflict of sound frequencies. It is said that the note rolls, because of the drum rolling sound that this phenomenon can produce. A frequency conflict may exist on the same string when the sound is not the same on each side of the bridge and / or between a string and vibratory frequencies of some parts of the instrument. This problem is currently combated by the addition of a weight on the string, which has the effect of muffling with a muted effect the second sound frequency and therefore reduce the noise conflict.

The wolf tuner solves the conflict of sound frequency by modifying the parasitic frequency, matching the note played on the instrument when it rolls and adding its own resonance which enriches the timbre of the instrument.

State of the art

In the current state of the art, several accessories, substantially different, are proposed to remedy the problem of the wolf. Nevertheless, none of them offers a fully satisfactory solution because their use is always accompanied by various disadvantages. These anti-roll mechanisms, also commonly called "wolftôter", are based on the use of a weight to neutralize the sound frequency that conflicts with the note played. But this process has the disadvantage of generating a muted effect and therefore adversely affect the quality of the sounds emitted.

The design of the Wolf Tuner is not based on its weight but on its own resonance.

Thanks to its curved shape, the wolf tuner is very easy to put on, to remove and can be easily moved "during play" by its user. This solution does not damage the string, nor the instrument on which it is placed and leaves a great freedom to the musician.

Thanks to its minimal weight, its "U" shape and its silver composition, the wolf tuner not only does not attenuate the resonance of the instrument but adds its own resonance.

There exists on the market a wolftöter called: "wolf suppressor" fixing itself thanks to its curved shape but which is constituted by a cylinder of brass and which thus functions on the same principle as the classic wolftöter that is to say: a weight placed on the rope.

The cello wolf tuner is an instrument weighing 2.5 grams. Its lightness makes it possible not to cause a muted effect on the string, whereas the other systems for the cello, although claiming the same principle of lightness, weigh heavier and which thus have indeed a effect of mute.

Moreover, the wolf tuner is more aesthetic than current solutions, which is an advantage for its user.

The technical features of the invention are novel compared to the inventions contained in the current state of the art.

The wolf tuner does not work on the same principle as the traditional solutions: instead of fighting the unwanted sound frequency by adding a weight on the string, the invention allows to grant this sound to the rolling note. The operation of the invention is no longer based on the effect of its weight. Therefore, the conflict between the sound frequencies is avoided while not causing a muted effect. The Wolf Tuner adds its own resonance due to its "U" shape and its silver composition which enriches the timbre of the instrument.

A new solution to the problem of rolling is thus found, by going through another route, without causing undesirable effects.

Claims (2)

1. Accessory for string instrument to be fixed on one of the strings of an instrument, on the portion between the bridge and the tailpiece and for removing the bearing also called the "wolf", characterized in that it consists of a plate of silver, folded in the shape of a "U" and then bent lengthwise, so that the accessory, once placed on the rope, fits thanks to its curved shape, which allows the rope to be in contact with a point of the inner face (4) of the accessory and each of the ends (5 & 6) of the opposite part of the accessory. The inner radius (7) of the curve is 24 mm. The dimensions are, when intended for cello 1 mm thick, 20 mm long and 7.5 mm wide, when intended for violin or Γ alto 0.8 mm thick, 15 mm long and 5 mm wide. 2. Accessory according to claim 1 characterized in that, thanks to its "U" shape and its silver composition, it adds its own resonance, which enriches the tone of the instrument and optimizes the reduction of the bearing by granting the sound frequency emitted by the part of the string between the bridge and the tailpiece, with the sound frequency of the rolling note.
