Description

  The present invention relates to a woodwind instrument lead.

  For example, woodwind instruments such as a saxophone and a clarinet generate sound by vibrating a strip-shaped lead attached to a pit that a player breathes in. Woodwind reeds are generally made of natural materials such as bamboo and bamboo, and have a vamp (Vamp) whose surface has been scraped to gradually reduce the thickness toward the longitudinal end of the player's mouth. ) Is provided.

  The woodwind instrument reed formed from such a natural material has a drawback that individual variations are large. For this reason, even if the user is a non-skilled player with a relatively low level of skill, select a lead that provides a satisfactory tone from among multiple leads, and do not use a lead that does not provide a satisfactory tone. The actual situation is that they are discarded. Specifically, woodwind reeds are often sold as a set of 10 pieces, but even a general user judges that only 2 to 3 pieces can be used in practice. There are many cases to do.

  Moreover, it is inevitable that moisture contained in the player's saliva and breath adheres to the woodwind instrument reed. Woodwind reeds made of bamboo and bamboo have the disadvantage that their life is relatively short because degradation is accelerated by exposure to such moisture. For this reason, the lead | read | reed excellent in durability formed from the synthetic resin is also marketed. As a specific example, Japanese Patent Application Laid-Open No. 2001-75556 proposes forming a woodwind instrument lead from a liquid crystal polymer.

  Such synthetic resin leads are more expensive than leads made from natural materials, but because the quality is stable, you can use everything you have purchased and have excellent durability. Overall, it can be used at a much lower cost than leads made from natural materials. However, the conventional synthetic resin lead does not reach the lead formed from a natural material in terms of timbre, and is only used for practice.

JP 2001-75556 A

  In view of the above disadvantages, an object of the present invention is to provide a woodwind instrument lead that has a relatively small variation in quality and that is relatively excellent in timbre.

  The invention made to solve the above-mentioned problems is a strip-shaped woodwind instrument lead having a synthetic resin as a matrix and a vamp on one end in the longitudinal direction, wherein the vamp A woodwind instrument lead comprising a plurality of concave or convex strips parallel to each other in an overlapping region.

  The woodwind instrument lead has a plurality of concave or convex strips parallel to each other in a region overlapping with the vamp in at least a plan view of the front surface or the rear surface. It can generate a natural sound that is relatively close to the woodwind instrument reed formed from the material and a new sound in the ear that was not obtained in the past.

  The concave valley line or the convex ridge line may be along the longitudinal direction of the lead. In this way, the concave line or the ridge line is formed from a natural material by being along the longitudinal direction of the lead in the same manner as the direction of fibers in the woodwind instrument lead formed from a natural material. A natural tone that is closer to the reed for woodwind instruments.

  The cross-sectional shape of the plurality of grooves or ridges may vary depending on the position of the grooves or ridges in the longitudinal direction. Thus, by changing the cross-sectional shape of the plurality of grooves or ridges depending on the position in the longitudinal direction of the grooves or ridges, for example, vibration characteristics such as the first tone, the body tone, and the original tone are artificially created. The tone color can be adjusted.

  It has a plurality of concave stripes, and the opening width of the concave stripes is preferably larger than the bottom width. Thus, by having the plurality of concave stripes, and the opening width of the concave stripes being larger than the bottom width, it becomes easy to clean dirt such as saliva, and hygiene can be improved.

  The plurality of concave stripes or convex stripes may be formed on the surface of the vamp. As described above, since the plurality of grooves or ridges are formed on the surface of the vamp, the surface abutting on the mouthpiece can be flattened, and the plurality of grooves or ridges can be designed. However, it is not necessary to consider the shape change of the gap between the opening of the mouthpiece and the lead.

  As described above, the woodwind instrument lead of the present invention has a relatively small variation in quality and a relatively excellent tone.

It is a typical perspective view which shows the saxophone which uses the lead for woodwind instruments of one Embodiment of this invention. It is typical sectional drawing which shows the mouthpiece of the saxophone of FIG. FIG. 3 is a schematic plan view of the saxophone woodwind reed of FIG. 1.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings as appropriate.

[First embodiment]
FIG. 1 shows a saxophone which is a kind of woodwind instrument using a woodwind instrument lead 1 according to an embodiment of the present invention.

  The saxophone shown in FIG. 1 is provided with a mouthpiece 3 having a woodwind instrument lead 1 attached to one end of a saxophone body 2.

  The saxophone body 2 is provided with a mouthpiece 3 attached to one end and a bent tube portion 4 that is opened so that the other end is enlarged in diameter, and a plurality of sound holes formed in the tube portion 4 are provided. A plurality of keys 5 that can be sealed are provided, and a lever 6 for operating these keys 5 is provided. The configuration of the saxophone main body 2 can be the same as the configuration of the conventional saxophone main body.

  The mouthpiece 3 is attached to one end of the saxophone main body 2 and is used by a player to blow into the saxophone main body 2 and vibrate the woodwind instrument lead 1.

  As shown in FIG. 2, the mouthpiece 3 is formed in a substantially cylindrical shape, and has a shape in which one end side where the player gets into the mouth is flat and crushed, and the side in contact with the lower lip of the player is wide open. The woodwind instrument lead 1 is attached so as to seal the opening. The woodwind instrument lead 1 is fixed to the mouthpiece 3 by a ligature 7 attached to the outer periphery of the mouthpiece 3. As the mouthpiece 3 and the ligature 7, those having a conventional configuration can be used.

<Lead for woodwind>
FIG. 3 shows the detailed shape of the woodwind instrument lead 1. The woodwind instrument lead 1 is formed in a strip shape using a synthetic resin as a matrix, and has a bump 8 on one end side in the longitudinal direction.

  The woodwind instrument lead 1 has a plurality of concave strips (elongate grooves) 9 parallel to each other on the surface of the vamp 8. The plurality of concave stripes 9 imparts anisotropy to the vibration characteristics of the vamp 8. Specifically, the bending rigidity in the direction perpendicular to the plurality of concave stripes 9 is greater than the bending rigidity in the direction along the concave stripes 9. Greatly reduced. As a result, the woodwind instrument lead 1 can adjust the vibration characteristics of the vamp 8 by the concave strip 9, and can be brought close to the vibration characteristics of the woodwind instrument lead formed of a natural material. Therefore, the woodwind instrument lead 1 having the plurality of concave strips 9 can generate a relatively natural sound when attached to the woodwind instrument and played.

  The woodwind instrument lead 1 is curved so that the surface of the portion where the vamp 8 is not formed forms part of the cylindrical surface. The curved surface has a longitudinal axis parallel to the back surface and bulges to the front surface side. As a result, the woodwind instrument lead 1 is held integrally with the mouthpiece 3 by tightening the portion where the vamp is not formed with the ligature 7 as shown in FIGS.

  The vamp 8 is formed so as to gradually reduce the thickness of the woodwind instrument lead 1 toward the longitudinal end of the player's mouth. More specifically, the vamp 8 is generally curved so that the inclination angle becomes larger toward the heel (longitudinal end portion where the vamp 8 is not formed) of the woodwind instrument lead 1, and the tip side is substantially flat. Formed to stretch. The curved shape of the vamp 8 is the same as the curved shape with the vamp formed on the conventional lead.

  That is, the rough shape of the woodwind instrument lead 1 not taking into account the concave strip 9 is the same shape as a conventional lead formed from a bag or the like. As specific dimensions of the general shape of the woodwind instrument lead 1, when the woodwind instrument lead 1 is an alto saxophone lead, the width is about 15 mm, the length is about 70 mm, and the vamp 8 is formed. The maximum thickness of the unexposed portion is about 3 mm, and the thickness at the tip of the vamp 8 is about 0.15 mm.

  The lower limit of the elastic modulus of the material forming the woodwind instrument lead 1 is preferably 3000 MPa, and more preferably 4000 MPa. On the other hand, the upper limit of the elastic modulus of the material forming the woodwind instrument lead 1 is preferably 10,000 MPa, and more preferably 8000 MPa. When the elastic modulus of the material forming the woodwind instrument lead 1 is less than the lower limit, the sound speed may be small and the acoustic effect may be insufficient. On the contrary, when the elastic modulus of the material forming the woodwind instrument lead 1 exceeds the upper limit, the woodwind instrument lead 1 becomes too hard, and there is a possibility that sufficient vibration cannot be obtained. The elastic modulus is a value measured according to JIS-K7171 (2008).

  For example, polypropylene can be used as a synthetic resin that is a matrix of a material for forming the woodwind instrument lead 1. The material forming the woodwind instrument lead 1 may include, for example, natural fibers such as wood fibers and bamboo fibers, inorganic fibers such as glass fibers, and synthetic fibers such as polyamide fibers in the matrix. The fibers in the matrix improve the rigidity of the woodwind reed 1.

  Although it does not specifically limit as a minimum of the content rate of the fiber in the material which forms the said lead 1 for woodwind instruments, 10 mass% is preferable and 20 mass% is more preferable. On the other hand, the upper limit of the fiber content in the material forming the woodwind reed 1 is preferably 70% by mass, more preferably 60% by mass. When the content rate of the said fiber is less than the said minimum, there exists a possibility that the rigidity of the said lead 1 for woodwind instruments cannot fully be improved. Conversely, if the fiber content exceeds the upper limit, it may be difficult to form the woodwind instrument lead 1.

  The lower limit of the average length of fibers contained in the material forming the woodwind instrument lead 1 is preferably 3 μm, and more preferably 5 μm. On the other hand, the upper limit of the average length of fibers contained in the material forming the woodwind instrument lead 1 is preferably 50 μm, and more preferably 30 μm. If the average length of the fibers is less than the lower limit, the rigidity of the woodwind instrument lead 1 may not be sufficiently improved. On the other hand, when the average length of the fibers exceeds the upper limit, it may be difficult to manufacture the woodwind instrument lead 1 by injection molding.

  Thus, the physical property of a material becomes constant by forming the said lead 1 for woodwind instruments by the material which uses a synthetic resin as a matrix. For this reason, since the woodwind instrument lead 1 has a certain vibration characteristic, the timbre variation generated is small.

<Concave>
The plurality of concave stripes 9 are formed at substantially constant intervals on the entire surface of the vamp 8. The valley lines of these concave strips 9 are oriented along the longitudinal direction of the woodwind instrument lead 1.

  Accordingly, the longitudinal rigidity of the vamp 8 is relatively increased, and the vibration characteristic of the woodwind instrument lead 1 can be brought close to the vibration characteristic of the woodwind instrument lead formed of a natural material. Therefore, the woodwind instrument lead 1 having the plurality of concave strips 9 can generate a relatively natural sound when attached to the woodwind instrument and played.

  As shown in FIG. 4, the cross-sectional shape perpendicular | vertical to the longitudinal direction of the said several groove 9 can be made into the substantially square shape which has a pair of side surface and a bottom face. The opening width of the recess 9 is preferably larger than the bottom width. That is, it is preferable that the pair of side surfaces of the concave strip 9 having a quadrangular cross section is inclined so that the distance between the side surfaces becomes larger on the opening side.

  The lower limit of the angle of inclination of each side surface of the concave strip 9 with respect to the thickness direction of the woodwind instrument lead 1 is preferably 1 ° and more preferably 3 °. On the other hand, the upper limit of the inclination angle of each side surface of the concave strip 9 with respect to the thickness direction of the woodwind instrument lead 1 is preferably 45 °, more preferably 30 °. If the inclination angle of each side surface of the concave strip 9 with respect to the thickness direction of the woodwind instrument lead 1 is less than the lower limit, the releasability from the mold is insufficient when the woodwind instrument lead 1 is injection molded. There is a risk that the drainage performance of saliva, washing water, etc. of the recess 9 will be insufficient. On the other hand, when the inclination angle of each side surface of the concave strip 9 with respect to the thickness direction of the woodwind instrument lead 1 exceeds the upper limit, the rigidity in the direction perpendicular to the convex strip 10 is increased, thereby increasing the anisotropy of the vibration characteristics. Is weakened, and the effect of improving the timbre by the recess 9 may be insufficient.

  The lower limit of the average width of the entire plurality of concave strips 9 is preferably 10 μm, and more preferably 20 μm. On the other hand, the upper limit of the average width of the entire plurality of concave strips 9 is preferably 500 μm, and more preferably 200 μm. When the average width of the plurality of concave ridges 9 is less than the lower limit, it may be difficult to process the concave ridges 9. On the other hand, when the average width of the plurality of concave ridges 9 exceeds the upper limit, the concave ridges 9 may give the player a sense of incongruity, and the tone improvement effect by the concave ridges 9 may be insufficient.

  As a minimum of the average depth (average value of the maximum depth in each section) of concave 9, 10 μm is preferable and 20 μm is more preferable. On the other hand, the upper limit of the average depth of the groove 9 is preferably 300 μm, and more preferably 200 μm. When the average depth of the groove 9 is less than the lower limit, the tone improvement effect by the groove 9 may be insufficient. On the contrary, when the average depth of the groove 9 exceeds the upper limit, the groove 9 may give the player a sense of incongruity, or the processing of the groove 9 may be difficult.

  The lower limit of the average center interval (arrangement pitch) of the concave stripes 9 is preferably 0.1 mm, and more preferably 0.2 mm. On the other hand, the upper limit of the average center distance of the concave stripes 9 is preferably 2 mm, and more preferably 1 mm. When the average center space | interval of the groove 9 is less than the said minimum, there exists a possibility that the process of the groove 9 may become difficult. On the contrary, when the average center distance of the concave stripes 9 exceeds the above upper limit, the number of the concave stripes 9 decreases, so that the anisotropy of the vibration characteristics becomes weak, and the tone improvement effect by the concave stripes 9 may be insufficient. There is.

  Moreover, it is preferable that the corner of the recess 9 is chamfered in the cross-sectional shape. That is, it is preferable that the side surface and the bottom surface of the recess 9 and the surface of the vamp 8 are connected gently. Thereby, while improving the drainage property of the groove 9, it can make it hard to give a discomfort to a player. Further, by chamfering the corners of the concave strip 9, the woodwind instrument lead 1 can be easily formed by injection molding.

  The cross-sectional shape of the concave stripe 9 may vary depending on the position in the longitudinal direction. Thereby, the rigidity of the vamp 8 can be changed according to the position in the longitudinal direction.

  As such a change in the cross-sectional shape of the groove 9, the maximum depth in each cross-section of the groove 9 may be gradually decreased toward the tip of the vamp 8. As a result, it is possible to prevent the strength of the woodwind instrument lead 1 from becoming insufficient at the tip of the vamp 8.

  Further, the recess 9 may not be provided at the tip of the vamp 8. Thereby, since a too thin part is not formed in the front-end | tip part of the vamp 8, the fall of injection moldability can be prevented.

  Moreover, you may change the width | variety of the groove 9 with the position of a longitudinal direction. Thereby, the rigidity of the vamp 8 can be changed according to the position in the longitudinal direction. That is, the rigidity of the vamp 8 can be partially reduced by increasing the width of the recess 9 in a part of the longitudinal direction. Therefore, due to the change in the width of the concave strip 9, the tip of the vamp 8 has a softer tone, the longitudinal center of the vamp 8 has a relatively soft body tone, and the heel side of the vamp 8 has a relatively soft original tone. Can be granted. Thereby, it is possible to characterize the tone color of the woodwind instrument lead 1.

<Manufacturing method>
The woodwind instrument lead 1 can be manufactured by injection molding using a mold of a composition having a synthetic resin as a matrix. In order to keep the quality of the product constant, the woodwind instrument lead 1 has an end portion, in particular, a vamp 8, which tends to become unstable in filling the mold cavity with the resin composition after injection molding. The tip edge may be excised.

<Advantages>
As described above, the woodwind instrument lead 1 is made of a natural material by forming a plurality of concave strips 9 on the surface of the vamp 8 to impart anisotropy to vibration characteristics. Natural sound that is relatively close to can be generated.

  The woodwind instrument lead 1 is not limited to the saxophone as shown in FIG. 1, but can be used for other woodwind instruments such as clarinet. For example, a tree using two leads such as oboe and bassoon. It can also be used for wind instruments. In the case of a woodwind instrument using two leads, the woodwind instrument lead 1 is used for only one of the two leads, and the other lead does not have a conventional lead or a concave or convex shape formed from a natural material. A conventional resin lead may be used.

[Second Embodiment]
FIG. 5 is a partially enlarged cross-sectional view of the vamp 8 of a woodwind instrument lead 1a according to another embodiment of the present invention. The woodwind instrument lead 1a is formed in a band plate shape using a synthetic resin as a matrix, and has a bump 8 on one end side in the longitudinal direction.

  Further, the woodwind instrument lead 1 a has a plurality of ridges (elongated protrusions) 10 parallel to each other on the surface of the vamp 8.

  It can be considered that the woodwind instrument lead 1a in FIG. 5 is formed with ridges 10 in place of the recesses 9 of the woodwind instrument lead 1 in FIG. Therefore, the material of the woodwind instrument lead 1a in FIG. 5 and the schematic shape including the vamp 8 are the same as the material of the woodwind instrument lead 1 in FIG. Therefore, the description of the woodwind instrument lead 1a in FIG. 5 that is the same as the woodwind instrument lead 1 in FIG. 3 is omitted.

<Projections>
The plurality of ridges 10 are formed on the entire surface of the vamp 8 at regular intervals. The ridgelines of these ridges 10 are oriented along the longitudinal direction of the woodwind instrument lead 1a.

  As shown in FIG. 5, the cross-sectional shape perpendicular | vertical to the longitudinal direction of the said some protruding item | line 10 can be made into the substantially square shape which has a pair of side surface and a top surface. The width of the top surface of the ridge 10 is preferably smaller than the width of the bottom. That is, it is preferable that the ridge 10 has a trapezoidal cross section in which the pair of side surfaces are inclined so that the distance between the side surfaces becomes smaller on the top side.

  The lower limit of the angle of inclination of each side surface of the ridge 10 with respect to the thickness direction of the woodwind instrument lead 1a is preferably 1 ° and more preferably 3 °. On the other hand, the upper limit of the inclination angle of each side surface of the ridge 10 with respect to the thickness direction of the woodwind instrument lead 1a is preferably 45 °, more preferably 30 °. When the inclination angle of each side surface of the ridge 10 with respect to the thickness direction of the woodwind instrument lead 1a is less than the lower limit, the releasability from the mold is insufficient when the woodwind instrument lead 1a is injection molded. Or the drainage of the ridges 10 may be insufficient. On the other hand, when the inclination angle of each side surface of the ridge 10 with respect to the thickness direction of the woodwind instrument lead 1a exceeds the upper limit, the rigidity in the direction perpendicular to the ridge 10 is increased, so that the anisotropy of vibration characteristics is increased. May become weak, and the effect of improving the timbre by the ridges 10 may be insufficient.

  As a minimum of the average width | variety of the protruding item | line 10, 10 micrometers is preferable and 20 micrometers is more preferable. On the other hand, the upper limit of the average width of the ridges 10 is preferably 1000 μm, and more preferably 2000 μm. When the average width | variety of the protruding item | line 10 is less than the said minimum, there exists a possibility that the process of the protruding item | line 10 may become difficult, and there exists a possibility that the protruding item | line 10 may give an uncomfortable feeling to a player. On the contrary, when the average width of the ridges 10 exceeds the upper limit, the rigidity in the direction perpendicular to the ridges 10 increases, so that the anisotropy of the vibration characteristics is weakened, and the timbre improvement effect by the ridges 10 is insufficient. There is a risk of becoming.

  The lower limit of the average height of the ridges 10 (the average value of the maximum height in each cross section) is preferably 10 μm, and more preferably 20 μm. On the other hand, the upper limit of the average height of the ridges 10 is preferably 100 μm, and more preferably 50 μm. If the average height of the ridges 10 is less than the lower limit, the tone improvement effect by the ridges 10 may be insufficient. On the other hand, when the average height of the ridges 10 exceeds the upper limit, the ridges 10 may give the player a sense of discomfort or the processing of the ridges 10 may be difficult.

  As a minimum of the average center space | interval of the protruding item | line 10, 0.1 mm is preferable and 0.2 mm is more preferable. On the other hand, the upper limit of the average center interval of the ridges 10 is preferably 1 mm, and more preferably 0.5 mm. When the average center space | interval of the protruding item | line 10 is less than the said minimum, there exists a possibility that the process of the protruding item | line 10 may become difficult. On the contrary, when the average center space | interval of the protruding item | line 10 exceeds the said upper limit, there exists a possibility that the timbre improvement effect by the protruding item | line 10 may become inadequate by the number of the protruding item | line 10 reducing.

  Further, it is preferable that the ridges 10 have chamfered corners in the cross-sectional shape. That is, it is preferable that the side surface of the ridge 10 and the top surface and the surface of the vamp 8 are connected gently. Thereby, while improving the drainage property of the protruding item | line 10, it can make it hard to give a discomfort to a player. Further, by chamfering the corners of the ridges 10, the woodwind instrument lead 1a can be easily formed by injection molding.

  The cross-sectional shape of the ridge 10, that is, the maximum height and width in each cross-section of the ridge 10 may vary depending on the position in the longitudinal direction. Thereby, it is possible to characterize the tone color of the woodwind instrument lead 1a.

[Third embodiment]
FIG. 6 is a partially enlarged cross-sectional view of a vamp 8 of a woodwind instrument lead 1b according to another embodiment of the present invention. The woodwind instrument lead 1b is formed in a band plate shape using a synthetic resin as a matrix, and has a bump 8 on one end side in the longitudinal direction.

  Further, the woodwind instrument lead 1 b has a plurality of recesses 9 and a plurality of protrusions 10 parallel to each other on the surface of the vamp 8. In the woodwind instrument lead 1b, the concave stripes 9 and the convex stripes 10 are alternately arranged.

  The material of the woodwind instrument lead 1b in FIG. 6 and the schematic shape including the vamp 8 are the same as the material of the woodwind instrument lead 1 in FIG. 6 is the same as the groove 9 in the woodwind instrument lead 1 in FIG. 4, and the protrusion 10 in the woodwind lead 1b in FIG. This is the same as the ridge 10 in the woodwind instrument lead 1a. Therefore, the description of the woodwind instrument lead 1b in FIG. 6 that is the same as the woodwind instrument lead 1 in FIG. 3 or the woodwind instrument lead 1a in FIG. 5 is omitted.

  Since the woodwind instrument lead 1b includes the plurality of concave strips 9 and the plurality of convex strips 10, the anisotropy of the vibration characteristics of the vamp 8 can be further increased.

  In addition, the woodwind instrument lead 1b increases the rigidity in the longitudinal direction of the woodwind instrument lead 1b by increasing / decreasing the number of the grooves 9 and the protrusions 10 so that the ratio of both is kept constant at the time of designing. The rigidity in the width direction (short direction) can be changed while being kept substantially constant.

[Fourth embodiment]
FIG. 7 shows a woodwind instrument lead 1c according to another embodiment of the present invention. The woodwind instrument lead 1c is formed in a band plate shape using a synthetic resin as a matrix, and has a bump 8 on one end side in the longitudinal direction.

  Further, the woodwind instrument lead 1 c has a plurality of concave strips 9 c parallel to each other on the surface of the vamp 8. The plurality of recesses 9c are formed so that each valley line is along the width direction of the woodwind instrument lead 1c.

  In the woodwind instrument lead 1c of FIG. 7, except for the direction of the trough line of the groove 9c, the material and the general shape, the cross-sectional shape of the groove 9c and the average center interval are the same as the material of the woodwind lead 1 of FIG. This is the same as the general shape, the cross-sectional shape of the concave strip 9 and the average center interval. Therefore, the description of the woodwind instrument lead 1c in FIG. 7 that is the same as the woodwind instrument lead 1 in FIG. 3 is omitted.

  The woodwind instrument lead 1c is formed such that the plurality of recesses 9c cross the vamp 8 in the width direction, and the rigidity of the vamp 8 is greatly reduced in the longitudinal direction by the recesses 9c. For this reason, the woodwind instrument lead 1c is relatively different in vibration characteristics from a lead formed from a conventional natural material having relatively large longitudinal rigidity. As a result, when the woodwind instrument lead 1c is used by being attached to a mouthpiece of a woodwind instrument, a new timbre can be produced in an ear that is relatively different from the conventional one. In other words, by using the woodwind instrument lead 1c, it is possible to form a woodwind instrument having a characteristic and attractive tone that is not present in the past.

[Fifth embodiment]
FIG. 8 shows a woodwind instrument lead 1d according to another embodiment of the present invention. The woodwind instrument lead 1d is made of a synthetic resin as a matrix, is formed in a band plate shape, and has a bump 8 on one end side in the longitudinal direction.

  Further, the woodwind instrument lead 1d is formed on the surface of the vamp 8 with a plurality of concave strips 9 that are symmetrical in the width direction and whose valley line is inclined with respect to the longitudinal direction of the woodwind instrument lead 1d. ing.

  In the woodwind instrument lead 1d of FIG. 8, except for the direction of the valley line of the groove 9d, the material and the general shape, the cross-sectional shape of the groove 9d, and the average center interval are the same as the material of the woodwind instrument lead 1 of FIG. This is the same as the general shape, the cross-sectional shape of the concave strip 9 and the average center interval. Therefore, the description of the woodwind instrument lead 1d in FIG. 8 that is the same as the woodwind instrument lead 1 in FIG. 3 is omitted.

  In the woodwind instrument lead 1d, since the plurality of concave strips 9d are arranged to be inclined, the rigidity of the vamp 8 becomes relatively large in the direction along the inclination angle of the concave strip 9d. Accordingly, the sound generated by the woodwind instrument lead 1d has a different timbre depending on the inclination angle of the groove 9d. In other words, the woodwind instrument lead 1d can adjust the timbre by the inclination angle of the groove 9d.

[Sixth embodiment]
FIG. 9 shows a woodwind instrument lead 1e according to another embodiment of the present invention. The woodwind instrument lead 1e is made of a synthetic resin as a matrix, is formed in a strip shape, and has a bump 8 on one end side in the longitudinal direction.

  The woodwind instrument lead 1e has a plurality of concave strips 9 formed in parallel to each other in a region excluding the vicinity of the outer edge of the back surface of the vamp 8, that is, a region not in contact with the mouthpiece 3. The plurality of concave strips 9 are oriented such that the valley lines are along the longitudinal direction of the woodwind instrument lead 1.

  In the woodwind instrument lead 1e shown in FIG. 9, except for the position where the recess 9e is disposed, the material and the approximate shape, the cross-sectional shape of the recess 9e, and the average center distance are the same as the material and outline of the woodwind instrument lead 1 shown in FIG. This is the same as the shape, the cross-sectional shape of the recess 9 and the average center distance. Therefore, the description of the woodwind instrument lead 1e in FIG. 9 that is the same as the woodwind instrument lead 1 in FIG. 3 is omitted.

  The woodwind instrument lead 1e is provided with a plurality of grooves 9 on the back surface of the vamp 8, so that the player does not directly touch the grooves 9, and the player feels uncomfortable even when the grooves 9 are relatively large. I don't feel it.

  Further, since the plurality of concave stripes 9 are formed in a region that does not come into contact with the mouthpiece 3, it does not promote characteristic changes due to wear.

[Other Embodiments]
The said embodiment does not limit the structure of this invention. Therefore, in the above-described embodiment, components of each part of the above-described embodiment can be omitted, replaced, or added based on the description and common general knowledge of the present specification, and they are all interpreted as belonging to the scope of the present invention. Should.

  The woodwind instrument lead may have a concave line or a convex line on the front surface and the back surface, respectively. In this case, it is relatively easy to maintain the rigidity in the longitudinal direction of the woodwind instrument lead when the design is changed by providing a concave stripe on one of the front and back surfaces and a convex stripe on the other. That is, it is possible to cancel the rigidity change due to the increase / decrease of the concave stripes and the rigidity change due to the increase / decrease of the convex stripes at the time of design change.

  In the woodwind instrument lead, the groove or ridge may be formed in a region overlapping at least a part of the vamp in plan view, or may be formed to extend in a region not overlapping with the vamp in plan view. .

  In the woodwind instrument lead, the interval between the concave stripes or the center of the convex stripes may not be constant. As an example, in 1st thru | or 3rd embodiment, the center space | interval of a groove or a protrusion may differ in the width direction center vicinity area | region and the width direction both ends vicinity area | region.

  When it has a plurality of concave stripes and a plurality of convex stripes, the arrangement of the concave stripes and the convex stripes may not be alternate.

  Similarly, in the fourth to fifth embodiments of the woodwind instrument lead, a convex shape may be provided instead of the concave stripe or in addition to the concave stripe.

  The woodwind instrument lead may have a ridge on the back surface of the vamp. Further, the concave stripes or the convex stripes may be formed in a region in contact with the mouthpiece on the back surface of the vamp.

  In the woodwind musical instrument lead, the cross-sectional shape of the groove or ridge is not limited to a square shape, and may be, for example, a semicircular shape or an elliptical shape.

  In the woodwind instrument lead, for example, as in the fifth embodiment, it is preferable that the grooves or ridges do not intersect in a lattice shape when the ridges or ridges have different directions. This is because if the concave stripes or the convex stripes intersect, there is a risk that saliva or the like may not be easily discharged at the intersection. Therefore, the left and right symmetrical concave grooves of the woodwind instrument lead of the fifth embodiment may be formed separately from each other so as not to extend on the axis of symmetry.

  The woodwind musical instrument lead is not limited to injection molding, and may be formed, for example, by cutting out from a block or plate material.

  The reed for woodwind instruments of the present invention can be widely used not only for saxophones but also for other woodwind instruments using reeds.
