An object to be solved by the present invention is to provide a new reed for a woodwind instrument that can obtain a sound reduction effect.

The present invention that solves the above problems is a lead for a woodwind instrument having a slit extending downward from the tip. By providing the slit, the vibration of the lead is suppressed, and the sound reduction effect can be obtained.

The present invention is preferably applied to single reeds for woodwind instruments.
More specifically, the present invention is preferably applied to saxophone reeds.

In a preferred embodiment of the present invention, the length of the slit is 50% or less of the length of the lead. By setting the length of the slit in the above range, it is possible to obtain a good sound reduction effect while maintaining the structural strength of the lead.

In a preferred embodiment of the present invention, the slit width is constant in the entire length of the slit or a part of the rear end side. With such a form, a good sound reduction effect can be obtained in spite of a simple structure.

In a preferred embodiment of the present invention, on the tip side of the slit, the slit width gradually increases from the rear end side of the lead toward the tip side. By adopting a structure in which the slit width gradually increases toward the tip side, the surface area of the lead itself becomes smaller. Since woodwind instruments generate sound by the vibration of reeds, adopting this structure with a smaller surface area leads to the realization of a better sound reduction effect. In addition, by adopting this structure, it is possible to enhance the breath-releasing effect and further improve the sound reduction effect.

The present invention also relates to a method for reducing the sound of a woodwind instrument, which comprises attaching the above-mentioned reed for a woodwind instrument to the woodwind instrument.

According to the present invention, the sound reduction effect of a woodwind instrument can be obtained.

Hereinafter, embodiments of the present invention will be described with reference to the drawings as appropriate. Needless to say, the scope of the present invention is not limited to the embodiments shown below.

An embodiment of the present invention is shown in FIG. The lead 10 is a lead for a saxophone. A slit 11 extends downward from the tip of the lead 10. By providing the slit 11 in this way, the vibration of the lead 10 is suppressed, and the sound reduction effect can be obtained.

In the slit 11, the width of the slit 11 gradually increases from the rear end side of the lead toward the tip side on the tip side of the slit 11 (the portion L22 in FIG. 1). By adopting a configuration in which the tip side of the slit 11 is widened in this way, the surface area of the lead itself is reduced. Since woodwind instruments generate sound by the vibration of reeds, adopting this structure with a smaller surface area leads to the realization of a better sound reduction effect. In addition, it becomes easier for the performer to breathe out, and a higher sound reduction effect can be obtained. In the present specification, the widened portion of the tip of the slit 11 is referred to as a widened portion.

The slit width is constant at a part of the rear end side of the slit 11 (L21 in FIG. 1). In the present specification, the portion of the slit 11 in which the slit width is constant is referred to as a slit width constant portion.

FIG. 1 shows an embodiment including a widened portion and a constant slit width portion, but the present invention is not limited to this embodiment. As shown in FIG. 2, the slit width may be constant over the entire length of the slit 11 (FIG. 2). That is, the total length of the slit 11 may be configured by the slit width constant portion.

The slit width in the constant slit width portion is not particularly limited, but may be preferably in the range of 0.1 to 1 cm, more preferably 0.2 to 0.8 cm, and further preferably 0.3 to 0.7 cm. ..
By providing a certain width in this way, the performer can breathe out and a higher sound reduction effect can be obtained.

Further, there may be an embodiment in which there is no slit width in the slit 11 (FIG. 3). In the form shown in FIG. 3, a crack extending downward from the tip of the lead 10 constitutes the slit 11.
Even in the form of providing the slit 11 having no slit width as described above, the vibration of the lead 10 can be suppressed, whereby the sound reduction effect can be obtained.

Returning to the description of the embodiment shown in FIG. 1 again. In the embodiment shown in FIG. 1, the width of the tip of the spread portion is not particularly limited, but is preferably in the range of 0.3 to 2 cm, more preferably 0.4 to 1.5 cm, and further preferably 0.5 to 1 cm. Can be designed to. This makes it possible to obtain a higher sound reduction effect.

The length L22 of the spread portion in the vertical direction can be preferably 0.1 to 2 cm, more preferably 0.2 to 1 cm, still more preferably 0.3 to 0.8 cm. This makes it possible to obtain a higher sound reduction effect.

The ratio of the vertical length L22 of the widened portion to the vertical length L21 of the constant slit width portion is not particularly limited, but is preferably 1:10 to 1: 1 and more preferably 1: 7 to 1: 1. 2, more preferably 1: 5 to 1: 3 can be designed. By designing in such a range, a high sound reduction effect can be obtained.

The length L2 of the slit 11 in the vertical direction can be designed to be preferably in the range of 0.1 to 5 cm, more preferably 0.5 to 3 cm. By designing in such a range, a high sound reduction effect can be obtained.

The length L2 of the slit 11 in the vertical direction can be preferably 50 & or less, more preferably 40% or less, still more preferably 30% or less with respect to the lead length L1. By designing in such a range, a high sound reduction effect can be obtained.

The lead 10 is attached to the saxophone using a ligature. Since pressure is applied to the reed 10 by the ligature, it is preferable that the lower end of the slit 11 is located above the ligature when the reed 10 is attached to the saxophone. That is, the slit 11 is preferably located above the heel of the lead 10.

As shown in FIG. 4, the slit 11 is preferably within the range of the vamp of the lead 10. That is, the vertical length L2 of the slit 11 is smaller than the vertical length L3 of the vamp. More specifically, L2 is preferably 80% or less, more preferably 60% or less, still more preferably 50% or less of L3. By setting the length L2 of the slit 11 in the vertical direction to such a length, it is possible to secure the structural strength of the lead 10 while obtaining the sound reduction effect.

The number of slits 11 is not limited, but is preferably 1 to 3, more preferably 1 to 2, and even more preferably 1.

As shown in FIGS. 1 to 3, the slit 11 is preferably provided substantially in the center of the lead 10. As a result, the sound reduction effect can be obtained more efficiently.

Examples of the material of the lead 10 include a wood material, a resin material, and a composite material of the wood material and the resin material. Examples of wood-based materials include reeds and bamboo. Examples of the resin-based material include polypropylene, polyamide, polyester and the like. The resin-based material may contain a resin serving as a matrix and reinforcing fibers. The material of the lead 10 is preferably a wood material, more preferably a reed.

Although the lead 10 is for a saxophone, the present invention can also be applied to other woodwind instruments. Specifically, the present invention relates to single-reed woodwind instruments such as clarinet and saxophone, double-reed woodwind instruments such as bassoon, oboe, bagpipe, kolangre, and auros, bamboo grass, harmonica, keyboard harmonica, accordion, concertina, and reed organ. It can be applied to free-reed woodwind instruments such as.

The slit lead of the embodiment of the present invention shown in FIG. 1 was attached to a tenor saxophone and played, and the sound was measured. Further, as a comparative example, a lead having the same shape as the slit lead of the embodiment of FIG. 1 was attached to the tenor saxophone except that the slit was not provided, and the sound was also measured. 5 and 6 show an embodiment, and FIGS. 7 and 8 show a spectroscope and a level meter of a comparative example.

As is clear from comparing the spectroscopes of FIGS. 5 and 7, it can be seen that the slit lead of the embodiment has a sound reduction effect over the entire wavelength range with respect to the lead of the comparative example. Further, when comparing the level meters of FIGS. 6 and 8, it can be seen that the slit lead of the example exhibits a sound reduction effect of 11.88 dB with respect to the lead of the comparative example.
This result shows that an excellent sound reduction effect can be obtained by providing a slit in the lead.
