Bell-inserted wind instrument silencer and lead with sound-reducing effect

The present invention relates to a silencer of a type that is inserted into a bell of a wind instrument such as a saxophone, a tuba, a trumpet, or a horn.
The present invention also relates to a reed of a woodwind instrument.

Conventionally, when practicing the performance of a wind instrument at home, a silencer is used to reduce the volume of the performance sound of the wind instrument. The mute has a body that can be partially inserted into the bell of the wind instrument, introduces the exhaled air of the performer emitted from the wind instrument into the body, and further, the introduced exhaled air is introduced through a hole having a relatively small diameter. By releasing it to the outside of the main body, the volume of the playing sound leaking to the outside is reduced. Documents that disclose such types of silencers include, for example, Patent Documents 1 and 2.

Also, when playing a wind instrument such as a saxophone at home, the volume is quite loud, and unless it is played in a specially designed soundproof room, the volume may be lowered in consideration of the influence on the neighborhood. Requested.

A structure in which a bypass tube is provided in the tube and pulled out to the outside of the musical instrument (Patent Document 4) and a structure in which the mouthpiece and the neck are provided with a bypass tube (Patent Document 5) have been proposed.
Further, a technique for suppressing the volume by giving a special structure to the lead has been proposed. Patent Document 6 discloses a wind instrument reed in which a vibration suppressing member that suppresses vibration is integrally formed with a reed body.

Patent No. 4114171 Patent No. 4986091 Utility Model Registration No. 3153666 Gazette Japanese Unexamined Patent Publication No. 2005-326810 Japanese Unexamined Patent Publication No. 2014-022933 Japanese Unexamined Patent Publication No. 2019-0401

The first problem to be solved by the present invention is to provide a novel silencer used by being attached to a bell of a wind instrument.
A second problem to be solved by the present invention is to provide a new reed for woodwind instruments capable of obtaining a sound reduction effect.

The present invention that solves the first problem is a wind instrument muffler used by being inserted into a bell of a wind instrument, and has an opening at the lower end, which is an insertion end to the bell, and a cavity inside. It is a silencer for musical instruments, characterized by having a dome-shaped silencer body.
The sound output from the bell through the tube of the wind instrument is led out to the internal cavity of the silencer body and reflected by the inner wall of the dome shell. As a result, the sound finally emitted to the outside of the wind instrument is attenuated, and the sound reduction effect is exhibited.

A preferred embodiment of the present invention is characterized in that a through hole is provided in the dome shell of the silencer body.
The air discharged from the inside of the wind instrument and led out to the internal cavity of the silencer body is discharged to the outside through the through hole provided in the dome shell. By securing the air passage in this way, a feeling of blowing without discomfort can be obtained.

A preferred embodiment of the present invention is characterized in that a plurality of the through holes are arranged at substantially equal intervals on the circumference of a circle centered on a substantially center in a plan view of the silencer body.
By adopting such a configuration, the sound reduction effect can be enhanced.

In a preferred embodiment of the present invention, a plurality of the through holes are arranged at substantially equal intervals on the circumferences of two or more concentric circles having different diameters, centered on a substantially center in a plan view of the silencer body. It is characterized by being.
By adopting such a configuration, it is possible to enhance the sound reduction effect while maintaining a feeling of blowing without discomfort.

In a preferred embodiment of the present invention, the inner diameter of the dome shell is equal to or less than the length of the inner diameter of the opening.
The bell of a wind instrument exerts the effect of amplifying the sound by the structure in which the inner diameter increases toward the outside. By adopting a configuration in which the inner diameter of the dome shell is equal to or less than the length of the inner diameter of the opening as in the above form, in other words, by not adopting a configuration in which the inner diameter expands toward the outside like a bell, sound reduction is achieved. The effect can be improved.

A preferred embodiment of the present invention is characterized in that the sound absorbing member is laid on the inner wall surface of the main body.
The sound output from the bell through the tube of the wind instrument is led out to the internal cavity of the silencer body and reflected on the inner wall surface of the dome shell. By covering the inner wall surface, which is the reflective surface, with a sound absorbing member, the sound reduction effect can be improved.

A preferred embodiment of the present invention is characterized in that the cavity of the silencer body is filled with a sound absorbing member.
The sound output from the bell through the tube of the wind instrument is led out to the internal cavity of the silencer body. By filling the internal cavity with a sound absorbing member, the sound reducing effect can be improved.

A preferred embodiment of the present invention is characterized in that a flexible non-slip member is provided on the outer wall surface on the lower end side of the silencer body.
When the wind instrument silencer of this form is inserted into the bell, the flexible non-slip member is deformed and adsorbed to the bell by the force of pushing the silencer body into the bell. Then, due to the pressure applied to the flexible non-slip member sandwiched between the muffler body and the bell, and the frictional force between the bell and the flexible non-slip member, the wind instrument muffler firmly becomes. It is fixed to the bell and will not come off unintentionally during performance.

The present invention that solves the above-mentioned second problem is a lead for a woodwind instrument in which a slit is extended downward from the tip. By providing the slit, the vibration of the reed 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 the 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 the 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 the 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 a woodwind instrument.

The present invention also relates to a wind instrument muffling set comprising the above-mentioned wind instrument silencer and the above-mentioned woodwind instrument reed.
By attaching the muffling set for wind instruments of the present invention to a wind instrument, a further sound reduction effect can be obtained.

According to the muffler for wind instruments of the present invention (the first invention) that solves the first problem, a good sound reduction effect can be obtained.
Further, according to the present invention (second invention) that solves the second problem, the sound reduction effect of the woodwind instrument can be obtained.

The embodiment of the present invention will be described, but it goes without saying that the present invention is not limited to the following embodiments.

<About the first invention>
[Example 1]
The wind instrument silencer according to the first embodiment of the present invention will be described with reference to FIGS. 1 to 5.
The wind instrument silencer of the first embodiment includes a dome-shaped silencer main body 10 having an opening at the lower end (FIGS. 2 and 5). The lower end of the silencer body 10 having an opening is the insertion end of the wind instrument into the bell (FIG. 4). The inside of the silencer body 10 is hollow (FIGS. 2 and 5).

In the present specification, the portion constituting the outer shell of the silencer main body 10 is referred to as a dome shell 101. Since there is a cavity inside the silencer body 10, the inner diameter can be thought of in the internal space of the dome shell 101. The inner diameter of the dome shell 101 is equal to or less than the length of the inner diameter of the opening of the silencer body 10 (FIG. 5). That is, the inner diameter of the dome shell 101 does not take a form of narrowing from the upper end to the lower end unlike a conventional typical silencer. In other words, the inner diameter of the dome shell 101 does not increase when viewed from the lower end to the upper end of the silencer body 10.
In the first embodiment, the dome shell 101 rises substantially vertically from the lower end to the upper end of the silencer body 10, and the inner diameter of the dome shell 101 is narrowed near the upper end (FIG. 5). Then, the dome shell 101 is completely narrowed at the upper end, and adopts a structure that closes the internal space of the silencer body 10 like a ceiling (FIG. 5).

The bell of a wind instrument exerts the effect of amplifying the sound by the structure that the inner diameter increases toward the outside. By adopting a configuration in which the inner diameter of the dome shell 101 is equal to or less than the length of the inner diameter of the opening as in the first embodiment, in other words, by not adopting a configuration in which the inner diameter expands toward the outside like a bell. The sound reduction effect can be improved.

The dome shell 101 is provided with a through hole that communicates the internal space of the silencer body 10 with the outside.
Specifically, the silencer main body 10 of the first embodiment is provided with a circular through hole 111 centered on a substantially center in a plan view (FIGS. 1, 4, and 5).
Further, in the dome shell 101 of the silencer main body 10, eight through holes 112, eight through holes 113, and eight through holes 114 are arranged in a circle and at equal intervals, respectively. These three types of through holes are arranged on the circumferences of each of the three concentric circles having different diameters, centered on the substantially center of the silencer body 10 in a plan view (FIG. 1).

In this way, it is good to arrange a plurality of through holes at substantially equal intervals on the circumferences of two or more concentric circles having different diameters, centered on the substantially center of the silencer main body 10 in a plan view. A good sound reduction effect can be obtained.
The number of through holes arranged at substantially equal intervals on the circumference is not limited to eight as in the first embodiment, and may be preferably 2 to 16, more preferably 4 to 12.

In the first embodiment, the shape of the through hole 111 provided in the center of the silencer main body 10 in a plan view is circular, but the shape is not limited to this, and may be a polygon such as a quadrangle or a star.

The shape of the through hole 112 arranged on the circumference of the circle centered on the substantially center of the plan view of the silencer body 10 is circular, but is not limited to this, and is a polygon such as a quadrangle or a star. You may.

The shapes of the through holes 113 and the through holes 114 arranged on the circumference of the circle centered on the substantially center of the plan view of the silencer main body 10 are not limited to the horizontally long quadrangle, but are not limited to this, for example, a vertically long quadrangle. It may have a vertically long slit shape, other polygons, or a circle.

The silencer main body 10 of the first embodiment is made of resin, but the present invention is not limited to this, and may be made of metal or wood. The forming method is not limited, and any known method such as molding by a 3D printer can be adopted even for injection molding.

A sound absorbing member 2 is laid on the inner wall surface of the silencer body 10 (FIGS. 2 and 5). That is, the sound absorbing member is provided in a layered manner so as to cover the inner wall of the silencer main body 10. As a result, the sound emitted from the tube of the wind instrument into the internal space of the silencer body 10 is attenuated by the sound absorbing member 2 in the process of reverberating on the inner wall of the silencer body 10.

In the first embodiment, the entire inner wall of the silencer main body 10 is covered with the sound absorbing member 2, but it is not necessary to cover all of them. The area of the inner wall is preferably 20% or more, more preferably 30% or more, still more preferably 40% or more, still more preferably 50% or more, still more preferably 60% or more, still more preferably 70% or more, still more preferably 80%. Is preferably covered with the sound absorbing member 2.
Further, it is preferable that the sound absorbing member 2 is covered with the sound absorbing member 2 so as to close at least all the through holes formed in the dome shell 101 from the inside (FIGS. 2 and 5).

In the first embodiment, the sound absorbing member 2 is a sponge, but the material thereof is not particularly limited as long as it has a sound absorbing effect. It is preferable to use a sponge that is porous and lightweight.

A flexible non-slip member 3 is provided on the outer wall surface on the lower end side of the silencer main body 10 of the first embodiment (FIGS. 1 to 5). When the wind instrument silencer 10 is inserted into the bell 4, the flexible non-slip member 3 is deformed and attracted to the bell 4 by the force of the silencer body 10 being pushed inside the bell 4. Then, due to the action of the pressure applied to the flexible non-slip member 3 sandwiched between the muffler main body 10 and the bell 4, and the frictional force between the bell 4 and the flexible non-slip member 3, for wind instruments. The silencer is firmly fixed to the bell 4 so that it will not come off unintentionally during the performance.

In the first embodiment, the flexible non-slip member 3 formed in a band shape is wound around the lower end side of the silencer body 10 (FIGS. 1 to 4). As described above, since the flexible non-slip member 3 covers the outer wall on the lower end side without a gap, there is no gap between the wind instrument silencer and the bell 4 when the bell 4 is inserted. As a result, all the sound and air emitted from the tube of the wind instrument are led out to the internal space of the muffler main body 10, and a good sound reduction effect can be obtained.

In Example 1, the flexible non-slip member 3 is made of a rubber sponge. The rubber sponge has excellent flexibility and non-slip properties, and is lightweight, so that there is no sense of discomfort when playing.

[Example 2]
The muffler for a wind instrument according to the second embodiment of the present invention will be described with reference to FIGS. 6 to 9. The description of the configuration common to the first embodiment will be omitted as appropriate.

The wind instrument silencer of Example 2 is also provided with a dome-shaped silencer main body 10 having an opening at the lower end (FIGS. 8 and 9), as in Example 1. The inside of the silencer body 10 is hollow (FIGS. 8 and 9).

The dome shell 101 rises substantially vertically from the lower end to the upper end of the silencer body 10, and the inner diameter of the dome shell 101 narrows near the upper end (FIG. 9). Then, the dome shell 101 is completely narrowed at the upper end, and adopts a structure that closes the internal space of the silencer body 10 like a ceiling (FIG. 9).

In the dome shell 101 of the silencer main body 10, eight circular through holes 115 and 16 vertically elongated slit-shaped through holes 116 are arranged in a circle and at equal intervals, respectively (FIGS. 6 and 7). .. These two types of through holes are arranged on the circumferences of two concentric circles having different diameters, centered on the substantially center of the silencer body 10 in a plan view (FIGS. 6 and 7).

A sound absorbing member 2 is laid on the inner wall surface of the silencer body 10 (FIGS. 8 and 9). In the second embodiment, the sound absorbing member 2 is not provided on the lower end side of the inner wall of the silencer main body 10, but the through hole 115 and the through hole 116 are all closed from the inside by the sound absorbing member 2. (Fig. 8, Fig. 9)

[Example 3]
The muffler for a wind instrument according to the third embodiment of the present invention will be described with reference to FIGS. 10 and 11. The description of the configuration common to Examples 1 and 2 will be omitted as appropriate.
In the wind instrument silencer of Example 3, the internal cavity of the silencer body 10 is filled with the sound absorbing member 2 (FIGS. 10 and 11). As a result, the sound emitted from the tube of the wind instrument into the internal space of the silencer body 10 is absorbed and attenuated by the sound absorbing member 2.
The sound absorbing member 2 in Example 3 is preferably a lightweight porous member such as a sponge or cotton.

<About the second invention>
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, on the tip side of the slit 11, the width of the slit 11 gradually increases from the rear end side of the lead toward the tip side (L22 portion in FIG. 12). By adopting a configuration in which the tip side of the slit 11 is widened in this way, the surface area of the vibrating portion of the reed 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 in a part of the rear end side of the slit 11 (L21 in FIG. 12). 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. 12 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. 13, the slit width may be constant over the entire length of the slit 11 (FIG. 13). 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. 14). In the form shown in FIG. 14, 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. 12 again. In the embodiment shown in FIG. 12, 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, and further 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 vertical length L2 of the slit 11 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 used by attaching it to the saxophone using a ligature. Since pressure is applied to the lead 10 by the ligature, it is preferable that the lower end of the slit 11 is located above the ligature when the lead 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. 15, the slit 11 is preferably within the vamp range 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. 12 to 14, 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.

The lead 10 is for a saxophone, but 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, korangre, and auros, bamboo grass, harmonica, keyboard harmonica, accordion, concertina, and reed organ. It can be applied to free-reed woodwind instruments such as.

<Others>
The present invention also relates to a wind instrument muffling set comprising the wind instrument muffler according to the first invention and the woodwind instrument reed according to the second invention. By attaching the muffling set for wind instruments of the present invention to a woodwind instrument, a stronger sound reduction effect can be obtained.

The slit lead of the second embodiment of the present invention shown in FIG. 12 was attached to the 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. 12 was attached to the tenor sack except that the slit was provided, and the sound was also measured. 16 and 17 show examples, and FIGS. 18 and 19 show comparative spectroscopes and level meters.

As is clear from comparing the spectroscopes of FIGS. 16 and 18, it can be seen that the slit lead of the example has a sound reduction effect over the entire wavelength range with respect to the lead of the comparative example. Further, when the level meters of FIGS. 17 and 19 are compared, 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.
