(First embodiment)
Hereinafter, a first embodiment of the present invention will be described. As shown in FIGS. 1-3, the wind instrument adapter 1 of this embodiment has the main body 1a and several protrusion part 12a-12l. The main bodies 1a and 12a to 12l are integrally formed and are made of a synthetic resin (plastic, more specifically, polyoxymethylene such as Delrin (registered trademark) or Duracon (registered trademark)).

  The main body 1a is a flat plate having a uniform thickness D (see FIG. 3, for example, 0.5 mm) and a width W1 (see FIG. 1, for example, 5 mm), and extends in an arc shape in the longitudinal direction. Further, both end portions 14 and 15 in the longitudinal direction of the main body 1a are close to each other and face each other.

  As will be described later, this wind instrument adapter 1 is mounted in a wind instrument (specifically, a clarinet), and has an air flow path in the wind instrument (a flow path in which air blown into the wind instrument by the player flows in the wind instrument). As will be described later, by arranging the sound so as to be surrounded by the sound, it is possible to improve the blowing comfort of the performer by improving the sound omission and further improve the sound quality of the wind instrument.

  As a configuration for this, on the inner peripheral surface of the wind instrument adapter 1, the plurality of protrusions 12a to 12l described above are directed from the main body 1a toward the inner side of the arc (more specifically, toward the center of the arc). It is formed to protrude. These protrusions 12 a to 12 l are formed at equal intervals on the inner peripheral surface of the wind instrument adapter 1. In addition, the protrusion shape of each protrusion part 12a-12l may mutually be the same as shown in FIG. 1, and may differ from each other.

  As a configuration for improving the blowing comfort and sound quality, a plurality of articulation grooves are further formed on the inner peripheral surface of the wind instrument adapter 1. FIG. 3 is an enlarged perspective view of a portion X in FIG. 2, and each of the plurality of grooves 13 corresponds to the above-described articulation groove. These articulation grooves 13 are not limited to the X portion, but over the entire inner peripheral surface of the wind instrument adapter 1 other than the X portion, and also on the inner peripheral surfaces of the protruding portions 12a to 12l, except for the protruding portions 12a to 12l. Is also formed on the inner peripheral surface (the inner peripheral surface of the main body 1a). The direction in which each of the articulation grooves 13 extends is a direction perpendicular to the plate surface of the wind instrument adapter 1 (the depth direction in FIG. 1), as shown in FIG.

  Each tuning groove 13 has a groove depth that is much smaller than the protrusion height W2-W1 of the protrusions 12a to 12l from the main body 1a, and the groove width is also much smaller than the protrusion width. For example, the wind instrument adapter 1 has an outer diameter R1 of 2.5 cm, an inner diameter R2 = R1-2 × W1 (an inner diameter of a portion other than the protruding portions 12a to 12l) of 1.9 cm, and a thickness D (see FIG. 3) of 0. When the average value (or any one representative value) of the protrusion heights W2 to W1 and the average value (or any one representative value) of the widths P is set to 5 mm, respectively. The depth and width of each tuning groove 13 are set to 0.05 mm or less, for example. In this example, the depth and width of each tuning groove 13 are 1/10 or less of the average (or any one representative value) of the protrusions 12a to 12l, but may be 1/5 or less. 1/20 or less, or 1/100 or less.

  Further, the total number of the articulation grooves 13 is much larger than the number of the projecting portions 12a to 12l. For example, it may be 5 times or more within the range matching with the above size, or 10 times or more. It may be 20 times or more, or 100 times or more.

  In addition, these tone adjustment grooves 13 are formed over the entire area of each of the protrusions 12a to 12l, and are formed over the entire area between adjacent protrusions. However, as another example, the protrusions 12a to 12l may be formed only on each of the protrusions 12a to 12l, and not to the protrusions 12a to 12l (the main body 1a).

  Due to the presence of the articulation groove 13, the protruding portions 12 a to 12 l on the inner peripheral surface of the wind instrument adapter 1 have a fine jagged shape.

  Here, each of the protrusions 12a to 12l and the tuning groove 13 may be formed by scraping the inner peripheral surface of the wind instrument adapter 1 using a file. In that case, the protruding portions 12a to 12l are formed using a relatively coarse file, and then the sound adjusting grooves 11a to 11e are formed using a relatively fine file. Or you may form the protrusion parts 12a-12l by notching the internal peripheral surface of the wind instrument adapter 1 using the punch which opens the hole of the external shape of the protrusion parts 12a-12l.

  With such a forming method, fine burrs (or fluff) may remain in the protrusions 12a to 12l and the tuning groove 13, but the effect of this embodiment described later is more when the amount of fine burrs remains is large. Increase more. From this, it can be seen that the more complex the shapes of the protrusions 12a to 12l and the tuning groove 13 are, the higher the effects (improving blowing comfort and sound quality) can be obtained.

  Next, a method for attaching the wind instrument adapter 1 to the clarinet will be described with reference to FIGS. As shown in FIG. 4, before connecting the barrel (tal) 5 of the clarinet and the upper tube 6, the wind instrument adapter 1 is interposed between the barrel 5 and the upper tube 6, and the wind instrument adapter 1 is inserted into the barrel 5. Thereafter, the tip of the upper tube 6 is inserted into the barrel 5.

  As shown in FIG. 5, a through hole 51, a mouthpiece insertion hole 52, and an upper tube insertion hole 53 are formed in the barrel 5 having the shape of a rotating body centered on the center line C. The mouthpiece insertion hole 52 is a hole into which an end portion of a mouthpiece (not shown) is inserted, and the upper tube insertion hole 53 is a hole into which an end portion of the upper tube 6 is inserted. (Corresponding to an example of an air flow path) is a hole that allows the mouthpiece insertion hole 52 and the upper tube insertion hole 53 to communicate with each other.

  The cross-sectional shapes of these holes 51 to 53 are coaxial circles with the center line C as the center in any cross section perpendicular to the center line C. Further, the diameter of the through hole 51 is smaller than the diameter of the mouthpiece insertion hole 52 and the diameter of the upper tube insertion hole 53. Accordingly, step portions 54 and 55 are formed at the connection portion between the through hole 51 and the mouthpiece insertion hole 52 and at the connection portion between the through hole 51 and the upper tube insertion hole 53.

  The wind instrument adapter 1 is inserted into the barrel 5 coaxially with the upper tube insertion hole 53 until it abuts on a step 55 at the connecting portion between the through hole 51 and the upper tube insertion hole 53. The diameter R1 (see FIG. 1) of the wind instrument adapter 1 is made slightly larger than the diameter of the upper tube insertion hole 53. Therefore, when inserting the wind instrument adapter 1 into the upper tube insertion hole 53, the operator deforms the wind instrument adapter 1 so as to narrow the gap between the end portions 14 and 15. Therefore, in the state where the wind instrument adapter 1 is in contact with the step 55, as shown in FIG. Therefore, the outer peripheral surface of the wind instrument adapter 1 presses the inner wall surface of the barrel 5 (more specifically, the inner wall surface surrounding the upper tube insertion hole 53) by the restoring force of the wind instrument adapter 1 to return to the original shape. It becomes. Because of this pressing force, the wind instrument adapter 1 is fixed in the barrel 5, and when the clarinet is played, the position of the wind instrument adapter 1 may fluctuate in the barrel 5 and the sound quality may become unstable. Reduced.

  The width W1 (see FIG. 1) of the main body 1a of the wind instrument adapter 1 is the same as or slightly smaller than the width S (see FIG. 5) of the stepped portion 55. However, the width (for example, the width W2 in FIG. 1) from the outer periphery of the main body 1a to the most protruding portion of each of the protruding portions 12a to 12l is larger than the width S as shown in FIG. For example, the width W2 is 1.1 times the width S.

  Therefore, as shown in FIG. 7, when the barrel 5 is viewed from the mouthpiece insertion hole 52 side, the protruding portions 12 a to 12 l can be seen beyond the through hole 51. It can be seen that the articulation groove 13 is formed in the entire area of the portion (a part of each of the protruding portions 12a to 12l) that can be seen through the through hole 51.

  The cylindrical hole (corresponding to a part of the air flow path) centered on the center line C opened in the upper tube 6 has a hole diameter substantially the same as the hole diameter of the through hole 51. Therefore, as shown in FIG. 8, in a state where the upper tube 6 is inserted into the upper tube insertion hole 53 of the barrel 5 and the wind instrument adapter 1 is sandwiched between the barrel 2 and the upper tube 6, the protrusions 12a to 12 of the wind instrument adapter 1 are formed. 12l protrudes toward the center line C, that is, toward the air flow path, with respect to the inner wall of the barrel 5 and the inner wall of the upper tube 6. The direction in which each of the tuning grooves 13 extends is parallel to the direction in which air flows in the air flow path.

  Hereinafter, the operation when playing the clarinet with the wind instrument adapter 1 mounted in this manner will be described. The air blown from the mouthpiece by the clarinet player enters a space surrounded by the inner peripheral surface of the wind instrument adapter 1 from the through hole 51 (air flow path) of the barrel 5 (hereinafter simply referred to as the inside of the wind instrument adapter 1). And further passes through an air flow path opened in the upper pipe 6.

  When air passes through the inside of the wind instrument adapter 1, the air is rectified by the protrusions 12a to 12l, so that the occurrence of turbulence is suppressed in the air flow path. As a result, the sound coming from the mouthpiece is improved, so that the player's blowing comfort is improved and the sound quality of the wind instrument is improved.

  Further, in addition to the protruding portions 12a to 12l, the effect that the sound entering from the mouthpiece is improved and the sound quality of the wind instrument are further improved due to the formation of a large number of the tuning grooves 13. .

  In the present embodiment, the instrument main body such as the barrel 5 and the upper tube 6 is not directly formed with a groove, but the wind instrument adapter 1 in which the projecting portions 12a to 12l are formed is attached to the instrument main body. This provides various advantageous effects.

  For the performer, there is a sense of resistance in processing the instrument body to form grooves. This is because once a groove is formed in the instrument body, it is no longer possible to restore it even if the sound is not improved to suit your taste. In contrast, the wind instrument adapter 1 of this embodiment can be easily attached. If you don't like the sound, just remove it.

  Further, the processing cost for forming the protrusions 12a to 12l and the tuning groove 13 in the wind instrument adapter 1 is the processing cost for forming the above-described protrusion and tuning groove on the inner wall of the air flow path of the instrument body. It is considered to be much smaller than that.

  As the wind instrument adapter 1 to be used, various wind instrument adapters having different combinations of thickness, material, number of protrusions, position, shape, number of articulation grooves, position, shape, etc. are prepared. You can select the wind instrument adapter that best suits your taste by wearing one adapter at a time and performing a trial performance. If you want to switch to a different sound quality for some reason, you can replace the current wind instrument adapter with a different combination of wind instrument adapters.

(Second Embodiment)
Next, a second embodiment of the present invention will be described with reference to FIGS. 9 is a perspective view of the wind instrument adapter 2 according to the present embodiment, FIG. 10 is a front view of the wind instrument adapter 2, FIG. 11 is an enlarged perspective view of a Y portion of FIG. 10, and FIG. It is XII-XII sectional drawing. 13 is a cross-sectional view of the wind instrument adapter 2 taken along the XIII-XIII cross section shown in FIG. 12 (a cross section parallel to the paper surface of FIG. 10 and passing through a protrusion 22a described later).

  As shown in FIGS. 9 to 13, the wind instrument adapter 2 of the present embodiment is obtained by bending a metal plate having a constant width (for example, 5 mm) and a constant thickness (for example, 0.3 mm) into an arc shape. It has a shape. The plate surface of each part of the wind instrument adapter 2 faces the center direction of the arc. The material of the wind instrument adapter 2 may be, for example, silver or an alloy containing copper and nickel (for example, Western silver).

  Further, the longitudinal ends 24 and 25 of the wind instrument adapter 2 are close to each other and face each other. As will be described later, the wind instrument adapter 2 is mounted in a wind instrument (specifically, a saxophone, a trumpet, a horn, a flute, etc.), and an air flow path in the wind instrument (flow path of air blown by a player). The sound quality of the wind instrument is improved by being arranged so as to surround.

  As a structure for this purpose, nine point-shaped protrusions 22a to 22i are formed at equal intervals on the inner peripheral surface of the wind instrument adapter 2 (the surface of the plate facing the center direction of the arc). ing. For example, as shown in FIGS. 12 and 13, these projecting portions 22 a to 22 i dent the outer peripheral surface of the wind instrument adapter 2 and project the back surface side (that is, the inner peripheral surface side) of the recessed portion. And can be formed. Each peripheral edge (boundary line between the protrusion and the non-protrusion part) of each of the protrusions 22a to 22i on the inner peripheral surface has an annularly closed shape.

  Furthermore, a large number of articulation grooves 23 (see FIGS. 11 and 13) are formed over the entire inner peripheral surface of the wind instrument adapter 2. For example, each articulation groove 23 is formed by scraping the inner peripheral surface of the wind instrument adapter 2 using a file. As shown in FIG. 11, the direction in which the articulation grooves 23 extend is parallel to the plate surface of the wind instrument adapter 2 and parallel to the width direction of the wind instrument adapter 2 (the depth direction in the drawing of FIG. 10).

  Each of the articulation grooves 23 is much smaller in height (depth) and width than the protrusions 22a to 22i. For example, the height and width of each protrusion 22a to 22i are each 1 mm, and the depth and width of each tuning groove 23 are 0.1 mm or less. In this example, the depth and width of each of the articulation grooves 23 are 1/10 or less of the protrusions 22a to 22i, but may be 1/5 or less, or 1/20 or less. 1/100 or less.

  Further, the number of the articulation grooves 23 is much larger than the number of the protrusions 22a to 22i, and may be, for example, 5 times or more, 10 times or more, or 20 times or more. It may be 100 times or more. In addition, these tone adjustment grooves 23 are also formed on each of the protrusions 22a to 22i, and are also formed on the inner surfaces other than the protrusions 22a to 22i. However, as another example, the protrusions 22a to 22i may be formed only on the entire inner surface other than the protrusions 22a to 22i. Or conversely, the tuning groove 23 may be formed on each of the protrusions 22a to 22i and not on the entire inner surface other than the protrusions 22a to 22i.

  Next, a method for attaching the wind instrument adapter 2 to the saxophone will be described with reference to FIG. As shown in FIG. 14, in the blow pipe (neck) 7 of the saxophone, a hole (air channel hole) formed in the mouthpiece side end 71 inserted into the mouthpiece (not shown) Insert the wind instrument adapter 2. Thereafter, the mouthpiece side end 71 is inserted into the mouthpiece. The blowing tube 7 is a well-known member interposed between a mouthpiece and a second tube (not shown; also referred to as a body), and a hole into which the wind instrument adapter 2 is inserted is an air flow path.

  In addition, the diameter R3 (refer FIG. 9) of the wind instrument adapter 2 is made a little larger than the hole diameter of the hole in the mouthpiece side edge part 71. As shown in FIG. Therefore, when inserting the wind instrument adapter 2 into the mouthpiece side end portion 71, the operator deforms the wind instrument adapter 2 so as to narrow the gap between the both end portions 24 and 25. Therefore, in a state where the wind instrument adapter 2 is mounted in the mouthpiece side end portion 71, the gap between the both end portions 24 and 25 is eliminated or narrowed. Therefore, the outer peripheral surface of the wind instrument adapter 2 presses the inner wall surface of the mouthpiece side end portion 71 due to the restoring force of the wind instrument adapter 2 to return to the original shape. Since the wind instrument adapter 2 is fixed in the blowing tube 7 by this pressing force, the position of the wind instrument adapter 2 may fluctuate in the blowing tube 7 at the time of playing the saxophone, and the sound quality may become unstable. Is reduced. Since the cross section of the hole in the mouthpiece side end 71 is circular, the wind instrument adapter 2 is in close contact with the inner wall of the hole in the mouthpiece side end 71. Therefore, no gap is generated between the inner wall of the hole at the mouthpiece side end 71 and the wind instrument adapter 2 during performance, and therefore air does not pass between the two.

  Next, a method for attaching the wind instrument adapter 2 to a wind instrument (for example, a trumpet or a horn) having a tuning pipe (plug / pull pipe) will be described with reference to FIG. As shown in FIG. 15, the wind instrument adapter 2 is inserted into a hole (air flow path) formed at one end of the tuning tube 8. Thereafter, the tuning tube 8 is inserted into the wind instrument.

  The relationship between the diameter R3 of the wind instrument adapter 2 (see FIG. 9) and the hole diameter of the hole at the one end of the tuning tube 8 is the relationship between the diameter R3 and the hole diameter of the hole in the mouthpiece side end 71. Is the same. Therefore, the wind instrument adapter 2 is fixed in the tuning tube 8 by the restoring force of the wind instrument adapter 2. Therefore, when the wind instrument is played, the possibility that the position of the wind instrument adapter 2 fluctuates in the tuning tube 8 and the sound quality becomes unstable is reduced. Since the cross section of the hole of the tuning tube 8 is circular, the wind instrument adapter 2 is in close contact with the inner wall of the hole of the tuning tube 8. Therefore, no gap is generated between the inner wall of the hole of the tuning tube 8 and the wind instrument adapter 2 during performance, and therefore air does not pass between the two.

  Next, a method for attaching the wind instrument adapter 2 to the flute will be described with reference to FIG. As shown in FIG. 16, the wind instrument adapter 2 is inserted into a hole (a hole in the air flow path) formed in the connecting portion 91 into which the head tube (not shown) is inserted in the main tube 9 of the flute. . Thereafter, the head tube is inserted into the mouthpiece.

  The diameter R3 (see FIG. 9) of the wind instrument adapter 2 is made slightly larger than the hole diameter of the hole in the connecting portion 91. Therefore, when the wind instrument adapter 2 is inserted into the connection portion 91, the operator deforms the wind instrument adapter 2 so as to narrow the gap between the both end portions 24 and 25. Therefore, in a state where the wind instrument adapter 2 is mounted in the connecting portion 91, the gap between the both end portions 24 and 25 is eliminated or narrowed. Therefore, the outer peripheral surface of the wind instrument adapter 2 presses the inner wall surface of the connection portion 91 by the restoring force of the wind instrument adapter 2 to return to the original shape. Since the wind instrument adapter 2 is fixed in the connecting portion 91 by this pressing force, the position of the wind instrument adapter 2 may fluctuate in the connecting portion 91 at the time of playing this flute and the sound quality may become unstable. Is reduced. In addition, since the cross section of the hole of the connection part 91 is circular, the wind instrument adapter 2 closely_contact | adheres to the inner wall of the hole of the connection part 91. FIG. Therefore, no gap is generated between the inner wall of the hole of the connecting portion 91 and the wind instrument adapter 2 during performance, and therefore air does not pass between the two.

  Moreover, the hole diameter of the hole in the connection part 91 becomes a little longer than the hole diameter of the hole (hole of an air flow path) provided in the other part of the main pipe 9 and communicating with the hole in the connection part 91. Yes. This is to eliminate a step between the inner wall of the head tube inserted into the connecting portion 91 and the inner wall of the portion other than the connecting portion 91 of the main tube 9. With such a structure, there is a stepped portion at the boundary between the hole of the connecting portion 91 and the hole of the other portion of the main pipe 9.

  When the wind instrument adapter 2 is inserted into the connection portion 91 and the head tube is further inserted, the wind instrument adapter 2 is sandwiched and fixed between the stepped portion and the tip of the head tube. Thereby, the step difference between the inner wall of the head tube and the inner wall of the connection portion 91 and the step difference between the inner wall of the connection portion 91 and the inner wall of the other air flow path of the main tube 9 are filled with the wind instrument adapter 2. Therefore, the possibility of turbulent flow in the main pipe 9 is reduced.

  Thus, in the state in which the wind instrument adapter 2 is inserted into the hole (air flow path) formed at one end of the blowing pipe 7, the tuning pipe 8, or the main pipe 9, the protrusions 22 a to 22 i are , Projecting toward the center line C, that is, toward the air flow path. The direction in which each of the tuning grooves 23 extends is parallel to the direction in which air flows in the air flow path.

  Hereinafter, an operation when playing a wind instrument (a saxophone, a wind instrument having a tuning tube or a flute) to which the wind instrument adapter 2 is mounted will be described. The air blown from the mouthpiece by the wind instrument player passes through the blowing pipe 7, the tuning pipe 8, or the main pipe 9.

  At that time, when air passes through the inside of the wind instrument adapter 2, the air is rectified by the protrusions 22a to 22i, so that the occurrence of turbulence is suppressed in the air flow path. As a result, the sound coming from the mouthpiece is improved, so that the player's blowing comfort is improved and the sound quality of the wind instrument is improved. In addition to the protrusions 22a to 22i, a large number of the tuning grooves 23 are formed, so that an effect equivalent to the effect caused by the tuning grooves 13 of the first embodiment can be obtained.

  Further, in addition to the protruding portions 22a to 22i, a large number of tuning grooves 23 are formed, thereby further improving the effect of improving sound removal from the mouthpiece and improving the sound quality of the wind instrument. .

(Regarding the effects of the articulation grooves 13, 23)
As described above, in the first and second embodiments, the provision of the articulation groove further increases the effect of improving sound removal from the mouthpiece and improving the sound quality of the wind instrument. The mechanism is still unclear.

  However, as a result of experiments conducted by the inventor of the present application on several tens of subjects, the effect is clearly shown. In the experiment, the test subject alternately played the wind instrument with the wind instrument adapter of each embodiment and the clarinet with the wind instrument adapter without the tuning groove from the wind instrument adapter of each embodiment. Let me judge.

  As a result, when an experiment was performed using a woodwind instrument such as a flute, almost 100% of the amateur players among the subjects judged that the lack of sound and the sound quality were significantly improved. However, many of the professional players among the subjects judged that the lack of sound and sound quality did not improve much. According to this experimental result, when playing a woodwind instrument, it can be said that the articulation groove has an effect of assisting an amateur player's blowing technique (air blowing technique).

  In contrast, in experiments using brass instruments such as horns and trumpets, 90% or more of the subjects, both amateur and professional players, judged that sound loss and sound quality were greatly improved. In particular, many professional players evaluate that they have hit the key (being able to catch the core of the sound) due to the addition of the articulation groove. According to this experimental result, when playing a brass instrument, it can be said that the articulation groove has an effect of assisting not only an amateur player but also a professional player's blowing technique (a technique for hitting a sound).
