Description

Technical Field

[0001] This invention relates to components for wind instruments and wind instruments themselves. Background Technology

[0002] Patent Document 1 discloses a muffler for a wind instrument as a component for altering the acoustic characteristics of a woodwind instrument. The muffler has a frame for housing a woodwind instrument and is capable of playing the woodwind instrument housed in the frame from the outside of the frame.

[0003] Because woodwind instruments have multiple tone holes, it is difficult to reduce the volume, which is one of their acoustic characteristics, compared to metal wind instruments with fewer or no tone holes. In contrast, the instrument muffler of Patent Document 1 reduces the volume of the woodwind instrument by housing it in its frame and covering its multiple tone holes.

[0005] Patent Document 1: Japanese Patent No. 6004159 Summary of the Invention

[0006] The technical problem that the invention aims to solve

[0007] However, in the instrument muffler of Patent Document 1, since the woodwind instrument is housed in the frame, the way to play the woodwind instrument changes significantly compared to the case where the woodwind instrument is not housed in the frame. For example, if the woodwind instrument is housed in the frame, the part for operating the woodwind instrument with the fingers is not visible, and the woodwind instrument becomes heavier with the weight of the frame, making it potentially difficult to play the woodwind instrument.

[0008] Based on the above, among woodwind instruments, compared with metal wind instruments, it is difficult to change the acoustic characteristics such as volume without altering the playing method.

[0009] The present invention was made in view of the above circumstances, and its object is to provide a component for a wind instrument that can change the acoustic characteristics of a wind instrument without changing the playing method of a woodwind instrument or other wind instrument, and a wind instrument having the component.

[0025] The following is for reference Figures 1 to 9 An embodiment of the present invention will be described.

[0026] like Figure 1As shown, the wind instrument 1 of this embodiment is a type of woodwind instrument, namely a clarinet. The wind instrument 1 includes a wind instrument body 2, a mouthpiece 3 (a component of the wind instrument), and a body 4. The wind instrument body 2 includes an upper tube 2A and a lower tube 2B with multiple keys 5 arranged on their outer surfaces, and a bell portion 2C. Figure 1 In the wind instrument 1 (clarinet), the mouthpiece 3, body 4, upper tube 2A, lower tube 2B, and bell 2C are arranged and connected in sequence. In the wind instrument 1 of this embodiment, the main body 2 and body 4 are the same components as those of a typical clarinet.

[0027] like Figure 2 As shown, the mouthpiece 3 has the same external shape as conventional mouthpieces, and together with a reed (not shown), it forms an inlet for blowing air into the wind instrument 1. The mouthpiece 3 has a cylindrical wall portion 10 with an inlet 101 and an outlet 102. The inlet 101 opens into a portion of a platform portion 10b1 on the outer cylindrical surface 10b of the outward-facing cylindrical wall portion 10, on which the reed is arranged in an overlapping manner.

[0028] like Figures 2 to 4 As shown, the cylindrical wall portion 10 is provided with an inner wall 11, an outer wall 12, and a filling pattern 13.

[0029] The inner wall 11 forms the inner cylindrical surface 10a of the inward-facing cylindrical wall portion 10. The outer wall 12 forms the outer cylindrical surface 10b of the cylindrical wall portion 10. The outer wall 12 is located at a position spaced apart from the inner wall 11 in the thickness direction of the cylindrical wall portion 10. Figure 3 , Figure 4 In this example, an inner wall 11 and an outer wall 12 are provided in a portion of the cylindrical wall portion 10. The inner wall 11 and the outer wall 12 may be provided, for example, in a portion of the cylindrical wall portion 10 with a larger thickness, or they may be provided throughout the entire cylindrical wall portion 10.

[0030] The filling pattern 13 is a structure used to fill the inner side of various shapes. The filling pattern 13 refers to a shape predetermined before manufacturing the mouthpiece 3 (a component for wind instruments) by means of 3D printing, etc., and is a repeatable shape. Therefore, for example, it is possible to manufacture multiple mouthpieces 3 with the exact same filling pattern 13. Specific shapes of the filling pattern 13 can be: lines (straight lines, curves), grids, polygons such as triangles; stars; honeycombs; spirals, etc.

[0031] like Figure 3 , Figure 4 As shown, in the mouthpiece 3, the filling pattern 13 is formed in the space S1 between the inner wall 11 and the outer wall 12.

[0032] The filling pattern 13 of this embodiment includes a plurality of protrusions 131 projecting from the inner surfaces 11a, 12a of the inner wall 11 and the outer wall 12, which are opposite to each other. The protrusions 131 of this embodiment are formed as columnar shapes, with both ends connected to the inner surfaces 11a of the inner wall 11 and the inner surfaces 12a of the outer wall 12. Figure 3 In the middle, multiple columnar protrusions 131 are arranged with gaps between them. Additionally, in Figure 3 In the middle, adjacent columnar protrusions 131 are parallel to each other. Figure 4 In the middle, the columnar protrusions 131 are arranged in a cross or parallel manner. The columnar protrusions 131 can be any columnar shape such as a quadrangular prism, a triangular prism, or a cylinder.

[0033] The cylindrical wall portion 10, including the filling pattern 13, is formed with a layered structure. That is, the cylindrical wall portion 10 is formed by stacking multiple layers. Hereinafter, refer to... Figure 5 , Figure 6 The photograph illustrates the layered structure.

[0034] Figure 5 The photograph shows an example of a mouthpiece 3 containing a cylindrical wall portion 10 formed by a layered structure. Figure 6 The photo is Figure 5 The photo shows a magnified view of area VI in the image. Figure 6 The scale lines in the photograph are spaced 1 mm apart. Figure 5 , Figure 6 Arrow D1 in the diagram indicates the stacking direction of multiple layers. For example... Figure 6 As shown, the cylindrical wall portion 10 is formed by a laminated structure, resulting in lamination marks 14 on the outer cylindrical surface 10b of the cylindrical wall portion 10. Lamination marks 14 are stripes (lines) indicating the boundaries between adjacent layers in the lamination direction D1. Figure 6 In the photograph, the stacking marks 14 are arranged at approximately 0.1 mm intervals in the stacking direction D1. Although not shown, the stacking marks 14 also appear on the inner cylindrical surface 10a of the cylindrical wall portion 10.

[0035] The nozzle 3, including such a cylindrical wall portion 10, is manufactured by 3D printing.

[0036] When manufacturing the mouthpiece 3 of this embodiment using 3D printing, the shape of the mouthpiece 3, including the aforementioned cylindrical wall portion 10, is determined in advance. Furthermore, the material used in manufacturing the mouthpiece 3 is selected. The layer spacing of the manufactured mouthpiece 3 is set. The filling pattern 13 included in the cylindrical wall portion 10 is set. The filling density of the cylindrical wall portion 10 (or the mouthpiece 3) is set. Figures 2 to 4In the illustrated mouthpiece 3, the filling density can be set to, for example, 20%. The order of these elements is not particularly limited. Then, the mouthpiece 3 is shaped according to the pre-defined shape, layer spacing, and filling pattern 13, thereby producing the mouthpiece 3.

[0037] As explained above, in the mouthpiece 3 of this embodiment, a filling pattern 13 is provided in the space S1 between the inner wall 11 and the outer wall 12 of the cylindrical wall portion 10. Therefore, the acoustic characteristics of the mouthpiece 3 of this embodiment are different from those of a conventional mouthpiece without the aforementioned space S1. Thus, the acoustic characteristics of the wind instrument 1 can be easily changed simply by replacing the conventional mouthpiece with the mouthpiece 3 of this embodiment.

[0038] Furthermore, the mouthpiece 3 of this embodiment has the same appearance as a regular mouthpiece. Therefore, the acoustic characteristics of the wind instrument 1 can be changed without altering the playing method of the wind instrument 1.

[0039] Furthermore, in the mouthpiece 3 of this embodiment, the cylindrical wall portion 10 containing the filling pattern 13 is formed in a layered structure. Such a mouthpiece 3 can be manufactured by 3D printing. Thus, even if the shape of the filling pattern 13 is complex, the cylindrical wall portion 10 containing the filling pattern 13 can be easily formed.

[0040] Furthermore, the mouthpiece 3 of this embodiment is manufactured by 3D printing, thus allowing for appropriate adjustment of the filling density of the cylindrical wall portion 10 (or the mouthpiece 3). If the filling density decreases, the rigidity of the cylindrical wall portion 10 (or the mouthpiece 3) decreases. As a result, the muting effect in the wind instrument 1 is enhanced, and the volume produced by the wind instrument 1 becomes smaller. Therefore, by adjusting the filling density, the volume produced in the wind instrument 1 using the mouthpiece 3 can be adjusted.

[0041] Furthermore, in the mouthpiece 3 of this embodiment, the filling pattern 13 includes a protrusion 131 that protrudes from at least one of the inner surfaces 11a and 12a of the inner wall 11 and the outer wall 12. Therefore, the rigidity of the inner wall 11 and the outer wall 12 can be improved by the protrusion 131. Thus, even if the thickness of the inner wall 11 and the outer wall 12 is relatively thin, the strength of the inner wall 11 and the outer wall 12 can be ensured.

[0042] Furthermore, the acoustic characteristics of the mouthpiece 3 can be altered based on the shape (size, position, etc.) of the protrusion 131. Therefore, it is possible to provide mouthpieces 3 with various acoustic characteristics.

[0043] Furthermore, in this embodiment, the mouthpiece 3 is a cylindrical component that is relatively easy to replace in the wind instrument 1. Therefore, by adopting the mouthpiece 3 of this embodiment, the acoustic characteristics of the wind instrument 1 can be easily changed.

[0044] The following is for reference Figures 7 to 9The experimental results shown illustrate the differences in acoustic characteristics between the mouthpiece 3 of this embodiment (hereinafter referred to as the mouthpiece 3 of the embodiment) and a conventional mouthpiece (hereinafter referred to as the mouthpiece of the comparative example).

[0045] Figure 7 This is a graph showing the change in volume over time when the mouthpiece 3 of the embodiment is used to play a long tone on an alto saxophone, a type of woodwind instrument. Figure 8 This is a graph showing the change in volume over time when playing a sustained note on an alto saxophone using the mouthpiece of the comparative example. That is, Figure 7 , Figure 8 The graphs for the illustrated embodiments and comparative examples are time-varying graphs when the same woodwind instrument (alto saxophone) is played using the same playing technique (long tone). Figure 7 , Figure 8 In the graph, the horizontal axis represents the time corresponding to the playing time, and the vertical axis represents the gauge pressure (Pa) corresponding to the volume of the alto saxophone.

[0046] like Figure 8 As shown, when using the mouthpiece of the comparative example, the pressure value corresponding to the volume is approximately greater than ±0.5 (Pa). On the other hand, as... Figure 7 As shown, when using the mouthpiece 3 of the embodiment, the pressure value corresponding to the volume is less than ±0.5 (Pa). That is, with the mouthpiece 3 of the embodiment, when played using the same playing method, the volume is lower compared to the mouthpiece of the comparative example. Therefore, it is clear that in the alto saxophone, the volume of the alto saxophone can be easily reduced simply by replacing the mouthpiece of the comparative example with the mouthpiece 3 of the embodiment. This reduction in volume (softness) is one of the changes in acoustic characteristics.

[0047] Figure 9 It is a graph showing the frequency characteristics of the alto saxophone using the mouthpiece 3 of the embodiment and the frequency characteristics of the alto saxophone using the mouthpiece of the comparative example. Figure 9 The horizontal axis of the graph represents frequency, and the vertical axis represents sound pressure level.

[0048] like Figure 9As shown, the frequency at which the sound pressure level peak occurs (peak frequency) is approximately the same regardless of whether the mouthpiece 3 of the embodiment or the mouthpiece of the comparative example is used. However, when using the mouthpiece 3 of the embodiment, compared to the case of using the mouthpiece of the comparative example, there is a tendency for the sound pressure level at the peak frequency to be lower at higher frequencies. This means that, compared to the tone of the alto saxophone using the mouthpiece of the comparative example, the tone of the alto saxophone using the mouthpiece 3 of the embodiment is a tone in which the volume of high notes (notes with high peak frequencies) is suppressed. Therefore, it can be seen that in the alto saxophone, the tone can be easily changed simply by replacing the mouthpiece of the comparative example with the mouthpiece 3 of the embodiment. Such a change in tone is one of the changes in acoustic characteristics.

[0049] The present invention has been described in detail above, but the present invention is not limited to the above embodiments, and various modifications can be made without departing from the spirit of the present invention.

[0050] In the mouthpiece 3 of the above embodiment, the protrusion 131 constituting the filling pattern 13 protrudes from at least one of the inner surfaces 11a and 12a of the inner wall 11 and the outer wall 12. That is, the protrusion 131 may, for example, be formed as a column with both ends connected to the inner surface 11a of the inner wall 11 or the inner surface 12a of the outer wall 12. Furthermore, the protrusion 131 may, for example, be formed as a column extending from the inner surface 11a and 12a of the inner wall 11 or the outer wall 12, but with its front end not reaching the inner surface 11a and 12a of the inner wall 11 or the outer wall 12. Furthermore, the columnar protrusion 131 is not limited to extending in a straight line, but may also extend in a curved shape. Furthermore, the protrusion 131 is not limited to being formed in a columnar shape, but may also be formed in other shapes such as a hemispherical shape. The hemispherical protrusion 131 may protrude from the inner surface 11a of the inner wall 11 or the inner surface 12a of the outer wall 12.

[0051] The wind instrument component of the present invention is not limited to the mouthpiece, but can also be applied to the body, for example. Figure 10 The illustrated cylinder 4A has the same external shape as conventional cylinders, namely, it has an annular cylindrical wall portion 20. In the cylindrical wall portion 20 constituting the cylinder 4A, similar to the mouthpiece 3 in the above embodiment, there is an inner wall 21 constituting the inner cylinder surface 20a of the cylindrical wall portion 20, an outer wall 22 constituting the outer cylinder surface 20b of the cylindrical wall portion 20, and a filling pattern 23 formed in the space S2 between the inner wall 21 and the outer wall 22. Figure 10 The filling pattern 23 shown, like the embodiment described above, includes a plurality of columnar protrusions 231 whose ends are connected to the inner surface 21a of the inner wall 21 and the inner surface 22a of the outer wall 22.

[0052] Figure 10 The illustrated cylinder 4A can also achieve the same effect as the mouthpiece 3 in the above embodiment.

[0053] In this invention, the cylindrical wall portion having an inner wall, an outer wall, and a filling pattern is not limited to components for wind instruments such as the mouthpiece 3 and the body 4A. For example, it can also be applied to the constituent elements of the main body 2 of a wind instrument, such as the upper tube 2A, the lower tube 2B, and the bell portion 2C. That is, the constituent elements such as the upper tube 2A, the lower tube 2B, and the bell portion 2C can also be components for wind instruments according to this invention.

[0054] This invention is not limited to the clarinet and alto saxophone exemplified in the above embodiments, but can be applied to any woodwind instrument. Furthermore, this invention is not limited to woodwind instruments, but can be applied to any wind instrument, including metal wind instruments.
