Description

    The present invention is a sound dampener and a method of using the same for reducing the sound of a bowed instrument.

Violin performances in a single room that is not a concert hall resonate as the sound is too loud. Of course, attention to the surroundings of loud sounds is necessary. To date, there are a wide variety of weak instruments for bowed instruments. However, these conventional weak sounds greatly reduce the harmonics of the original bowed instrument and bring about sound transformation. In addition, the conventional sound attenuator has a vibration damping effect as the weight increases, but the actual sound is altered, and the difference between the actual sound and the performance with the sound attenuator is large. The type that puts a heavy attenuator on the top of a violin genus resonates with the metal part of the attenuator and the string of the bowed instrument. This is because the greater the effect of the weak sound, the greater the difference from the original raw sound. As a result, the image of the song is greatly changed. Since the violin genus is made of pine, the heavier the sound, the lower the sound, so that the vibration of the bowed instrument piece is suppressed. However, the weight of the sound is limited. On the other hand, the type in which the plucked instrument piece is sandwiched between magnets and clip-like objects has a small sound reduction effect.

    The sound of a weak sound device that is inserted in the upper part of a conventional plucked instrument piece has deteriorated due to the muffled sound. The product of the present invention provides an appropriate sound reduction of the stringed instrument to be used and a sound that does not impair the original natural sound of the worn instrument.

The product of the present invention fixes the lower part of the piece of the bowed musical instrument to attenuate the vibration, and at the same time, disperses and attenuates the elastic wave transmitted to the soul column by the silencer curved surface member and the silencer piece device. In addition, the volume of the resonance generated from the f-shaped hole of the bowed instrument can be suppressed by blocking part or the entire f-shaped hole. As a result, the generated sound also changes depending on the area occupied by the f-shaped hole of the bowed instrument. There are many degrees of freedom in changing the sound quality inherent to bowed instruments. As described above, the product of the present invention greatly mitigates the change in sound caused by attaching a conventional sound attenuator, and reduces and reduces the change compared to the original sound unique to a bowed instrument.

A violin will be described as an example in the violin genus of a bowed instrument. The drawings that has been simplified. The scale of the drawing is arbitrary, and numbers and symbols are unified.

In addition, the circular silencer piece insulator member 12A and the long silencer piece insulator member 12B are collectively referred to as a silencer piece insulator member.

  The product of the present invention also prevents the cause of the violin damage due to the fall of the bowed instrument piece during performance practice. As an application example of the product of the present invention, various shapes and designs such as a diamond shape, a quadrilateral shape (Drawing 11), an ellipse, and a character are possible for the shape of the curved surface of the silencer. If the size of a stringed instrument such as a cello or a contrabass becomes large, the shape of the silencer curved surface member can be varied. In addition, a multilayered silencer curved body member can be expected to have a sound reduction effect. By using the silencer curved surface member of the present invention alone, it is possible to eliminate the wolf sound peculiar to a bowed instrument (FIG. 12).

     Although there is a difference in the volume of sound generated by each violin, according to the experiment of the present invention, the violin sound without using the sound attenuator was reduced to 77 decibels, and the swallow-type silencer curved body member 11C was reduced to 64 decibels. A normal metal sound attenuator (FIG. 10) was 61 dB. When this metal sound attenuator, donut-shaped silencer curved surface member 11A and circular silencer piece insulator 12A were used in combination, the reduction was 45 dB. As for the sound quality, the deterioration of sound was small and the sound could be reduced even when the conventional weak sounder and the product of the present invention were used in combination.
