Description

[Technical Field]

[0001] The present invention relates to musical instruments. [Background technology]

[0002] BACKGROUND ART Musical instruments having a rotary switching valve have been known in the past (see Patent Documents 1 and 2). Patent document 1 discloses a wind instrument that has a movable disk that rotates relative to a fixed disk in conjunction with the player's operation of an operating lever, and by rotating this movable disk the length of the main tube is extended to change the sound. Patent document 2 discloses a wind instrument that has a rotor that can be rotated between a first position in which the primary rotor inlet hole is aligned with the primary main body inlet hole and a second position in which each rotor hole is aligned with the main body hole, and that, depending on the rotation of the rotor, can directly connect the lead pipe to the main bore or insert a slide loop between them. Furthermore, conventionally, pipe instruments have been known that include a plurality of pipes and switch the pipe that produces sound based on key operation (see Patent Documents 3 and 4). For example, Patent Document 3 discloses that keyboards are provided corresponding to the respective musical scales, and each is configured to control the opening and closing of a valve via a rod. This valve is provided in a pressure chamber that communicates with a blower chamber equipped with a fan, and the airflow extracted from the pressure chamber through the valve is communicated via the corresponding air passage to pipes whose lengths are set corresponding to each musical scale. Furthermore, Patent Document 4 discloses a pipe organ toy in which the keys can be directly pressed by hand to push up the opening and closing means with an engaging arm, opening the valve member and playing the reed whistle. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Publication No. 2018-151522 [Patent Document 2] Japanese Patent Application Publication No. 53-96815 [Patent Document 3] Jikko No. 52-29946 [Patent Document 4] Japanese Patent Application Publication No. 11-231859 Summary of the Invention [Problem to be solved by the invention]

[0004] However, in conventional musical instruments, the rotary valves described above can shift from one scale to another by rotating the rotary member, but they cannot selectively output sounds by arbitrarily switching between multiple scales through rotation. The same is true for pipe instruments, which have not been able to freely switch between a large number of scales by rotating them to play a variety of melodies. In particular, woodwind and brass instruments are instruments that change the pitch by opening and closing tone holes, but many of them are not easy to play, as even a slight gap when closing the tone hole with a finger prevents the desired sound from being produced. Furthermore, there are no musical instruments that can produce sounds over a wide range of octaves, such as four octaves, and even if such instruments existed, they would likely be difficult to operate.

[0005] The present invention has been proposed to solve the problems associated with the prior art as described above, and aims to provide an instrument that has a wide range of several octaves and ergonomic operability suited to the fingers, thanks to a structure that corresponds to scale theory. [Means for solving the problem]

[0006] In order to achieve the above object, the musical instrument of the present invention comprises a group of rotating plates each having a plurality of tone holes stacked on top of one another, which are capable of connecting specific tone holes across the plurality of rotating plates depending on the combination of rotations of the rotating plates, and an oscillator unit which generates oscillation based on air that has passed through the connected tone holes, the plurality of tone holes being arranged so that the specific tone hole differs depending on the rotating plate being rotated, and the oscillator unit has oscillator means at positions corresponding to the different tone holes which are capable of oscillating different scales. [Effects of the Invention]

[0007] According to the present invention, it is possible to provide an instrument that has an unprecedented rational configuration and that allows performance over a wide octave range with simple operation. [Brief explanation of the drawings]

[0009] A musical instrument 1 of the present invention will be described with reference to the drawings. 1 is a front perspective view of the musical instrument 1. FIG. 2 is an exploded perspective view of the musical instrument 1. As shown in these figures, the musical instrument 1 has an overall shape similar to that of a saxophone, and is composed of various components such as a blowing section 100 including a mouthpiece 101, an upper air guide plate 150, a rotating plate group 200 consisting of a plurality of stacked rotating plates (R1 to R4, L1 to L3), a reed section 300 including a reed plate fixing section 330 and a lower air guide plate 350, and a sound output section 400 including a resonance section 410 and a bell section 420. When the player blows air into the mouthpiece of the instrument 1, the air passes through the blowing section 100 and the rotating plate group 200, causing the reed plate 320 (reeds 321 to 324) built into the reed section 300 to vibrate, and the oscillating sound resonates and vibrates inside the resonating section 410, after which the sound is emitted to the outside from the bell section 420. Each rotary plate is provided with operation keys (R1k to R4k, L1k to L3k) that can be rotated or not rotated by the player. This allows the player to use the operating keys with the fingers of both hands to rotate the rotating plate while blowing air into the mouthpiece 101, causing the air to pass through the sound holes h2 that are connected across all the rotating plates, vibrating the reed plates 320 (reeds 321 to 324) that are located at the positions of the sound holes h2 and producing the corresponding notes in the scale. Each component will be described below.

[0010] (Blowing section) The blowing section 100 is a part provided on the top of the musical instrument 1, and is composed of a mouthpiece 101, a blowpipe 102, a connecting section 103, and a fixing rod 104 (FIG. 2). The mouthpiece 101 is a part that the player puts his / her lips around and blows air into. The mouthpiece 101 is detachably attached to the blowpipe 102. Blowpipe 102 is a hollow tubular member provided between mouthpiece 101 and connecting part 103. Blowpipe 102 is composed of a curved pipe portion curved in an inverted U shape and a straight pipe portion extending vertically. The connecting part 103 is a truncated cone-shaped part for connecting the straight pipe part of the blowing pipe 102 and the upper air guide plate 150. The connecting part 103 has an opening in the center so that the upper part can be joined to the blowing pipe 102, and the lower part is open so that it can be joined to the upper air guide plate 150. The fixed rods 104 are four rod members each having a threaded portion at the tip. The fixing rod 104 is fastened to the connection portion 103, the upper air guide plate 150 (described later), the rotating plate group 200 (rotating plates R1 to R4, L1 to L3), the through holes provided in the lead portion 300, etc., and the threaded tapped hole provided in the resonating portion 410, and each part is fixed by this fastening.

[0011] (Upper air guide plate) The upper air guide plate 150 is a disc-shaped part provided between the blowing section 100 and the rotating plate group 200. The upper air guide plate 150 is provided with a sound hole h1 for guiding the air (wind) blown into the blowing section 100 into the rotating plate group 200. A screw 151 is fixed to the center of the upper air guide plate 150. The screw 151 rotates the air supplied from the upper blowpipe on the upper air guide plate 150, and thereby guides the air to each sound hole h1 while rotating the air. As a result, air with uniform pressure can be efficiently distributed to each sound hole h1 provided in the upper air guide plate 150.

[0012] FIG. 3 is a plan view of the upper air guide plate 150 as viewed from above. As shown in FIGS. 3(a) and 3(b), the upper air guide plate 150 has 48 sound holes h1 arranged according to a specific rule. For example, as shown in FIG. 3(a), four sound holes h1 are provided at each of the 1 o'clock, 2 o'clock, . . . 12 o'clock directions (also called clock positions) along the radial direction. That is, four sound holes h1 are provided at every 30 degrees of rotation angle on the circular plate of upper air guide plate 150. In this example, the 12 o'clock direction is the midpoint between the right operation keys such as R2k and the left operation keys such as L1k (i.e., the protruding direction of bell part 420). As shown in Figure 3(b), twelve tone holes h1 are provided along each of four circumferences (concentric circles) of different sizes, with the center point as the center. In this example, the circumferences are referred to as the first, second, third, and fourth circumferences in order from the farthest from the center. The size of each circumference has the following relationship: first circumference > second circumference > third circumference > fourth circumference. In other words, the upper air guide plate 150 has sound holes h1 at the intersections of the radial lines (dotted lines) from 1 o'clock to 12 o'clock shown in FIG. 3(a) and the first to fourth circular lines (dotted lines) shown in FIG. 3(b). The upper air guide plate 150 is configured so that air supplied from above can be supplied to the group of rotating plates 200 located below it via all the sound holes h1. However, as will be described later, the rotating plate group 200, which is tightly arranged below the upper air guide plate 150, is configured so that only a specific sound hole h2 is in communication with it, and therefore air can pass only through the sound hole h1 that corresponds to that specific sound hole h2, and therefore air is supplied to the rotating plate group 200 only through that sound hole h1.

[0013] (Rotating plates) The rotary plate group 200 is a component provided below the upper air guide plate 150 (FIGS. 1 and 2). FIG. 4 is an exploded perspective view of the rotary plate group 200. As shown in FIG. As shown in FIG. 4, the rotary plate group 200 has a layered structure in which seven rotary plates are stacked. Specifically, from above, the first right rotating plate R1, the second right rotating plate R2, the first left rotating plate L1, the third right rotating plate R3, the second left rotating plate L2, the fourth right rotating plate R4, and the third left rotating plate L3 are stacked. The first to fourth right rotating plates R1 to R4 can be rotated / non-rotated with the fingers of the right hand, and the first to third left rotating plates L1 to L3 can be rotated / non-rotated with the fingers of the left hand. In this way, by stacking the rotary plates for the right hand and the rotary plates for the left hand alternately, it is easy to hold with both hands and to operate with the fingers. Each rotating plate is formed to have a thickness about the same as the thickness of a human finger. This allows the fingers of both hands to be positioned at natural intervals on either side of each rotating plate when the musical instrument 1 is held with both hands. Furthermore, the rotary plate is provided with operation keys near the tips of the fingers when the instrument 1 is held with both hands. 7 and 8 are plan views of each rotating plate. Figure 7 is a plan view of each rotating plate when not rotating (OFF). (1) indicates the first right rotating plate, (2) the second right rotating plate, (3) the third right rotating plate, (4) the fourth right rotating plate, (5) the first left rotating plate, (6) the second left rotating plate, and (7) the third left rotating plate. Figure 8 is a plan view of each rotating plate when rotating (ON). (1) indicates the first right rotating plate, (2) the second right rotating plate, (3) the third right rotating plate, (4) the fourth right rotating plate, (5) the first left rotating plate, (6) the second left rotating plate, and (7) the third left rotating plate. As shown in Figures 4, 7 and 8, the first right rotating plate R1 has an operation key R1k located at approximately the 5 o'clock position, the second to fourth right rotating plates R2 to R4 have operation keys R2k to R4k located at approximately the 1 o'clock position, and the first to third left rotating plates L1 to L3 have operation keys L1k to L3k located at approximately the 11 o'clock position. By doing this, when the musical instrument 1 is held with both hands, the first right rotating plate R1 can be easily operated with the right thumb, the second right rotating plate R2 can be easily operated with the right index finger, the third right rotating plate R3 can be easily operated with the right middle finger, the fourth right rotating plate R4 can be easily operated with the right ring finger, the first left rotating plate L1 can be easily operated with the left index finger, the second left rotating plate L2 can be easily operated with the left middle finger, and the third left rotating plate L3 can be easily operated with the left ring finger. The instrument 1 can be fitted with a strap or belt (not shown), which can be placed around the player's neck or shoulders to support the instrument, allowing the player to play with both hands. In this way, the instrument 1 is provided with a rotating plate and operation keys in an ergonomic manner that is suited to the fingers and other parts of the hand, making it easy for the player to play.

[0014] More specifically, the rotating plate group 200 includes a first right rotating plate R1 that can be rotated counterclockwise by pushing out the right thumb, a second right rotating plate R2 that can be rotated clockwise by pulling back the right index finger, a third right rotating plate R3 that can be rotated clockwise by pulling back the right middle finger, a fourth right rotating plate R4 that can be rotated clockwise by pulling back the right ring finger, a first left rotating plate L1 that can be rotated counterclockwise by pulling back the left index finger, a second left rotating plate L2 that can be rotated counterclockwise by pulling back the left middle finger, and a third left rotating plate L3 that can be rotated counterclockwise by pulling back the left ring finger. Each rotating plate is configured to be able to rotate up to 15 degrees. For this reason, the state in which the rotating plate is rotated 15 degrees from the "non-rotating state" (initial state) is called the "rotating state," and the operation of changing the rotating plate from the "non-rotating state" to the "rotating state" is also called the "rotating operation" or "on operation." On the other hand, the operation of changing the rotating plate from the "rotating state" to the "non-rotating state" is also called the "off operation." Specifically, the second to fourth right rotating plates R2 to R4 can be put into a rotating state by rotating them 15 degrees clockwise through an "on operation," and the second to fourth right rotating plates R2 to R4 in a rotating state can be returned to a non-rotating state by rotating them 15 degrees counterclockwise through an "off operation." In addition, the first right rotating plate R1 and the first to third left rotating plates L1 to L3 can be put into a rotating state by rotating them 15 degrees counterclockwise with an "ON" operation, and can be returned to a non-rotating state by rotating them 15 degrees clockwise with an "OFF" operation. The "off operation" can be automatically performed by relaxing the fingers that performed the on operation, for example by removing the fingers from the operation keys. This structure will be described later.

[0015] FIG. 5 is an exploded perspective view of a first right rotating plate R1, which is an example of a rotating plate. As shown in FIG. 5, the first right rotating plate R1 is configured to include a rotating plate main body R1b, a rotating plate case R1c, a bearing 220, and a compression spring 240. The rotating plate main body R1b ​​is a main body part of the rotating plate. For this reason, the "rotating plate main body" is also called the "rotating plate." The rotary plate body R1b ​​is provided at its center with a shaft hole 211 of a size that allows the outer periphery of the bearing 220 to be joined without any gap. Furthermore, a plurality of sound holes h2 are provided on the plate surface of the rotary plate main body R1b. The rules for arranging the tone hole h2 will be explained in detail later in "About the arrangement of tone holes." Additionally, an operation key R1k and a spring support portion 212 that supports one end of the compression spring 240 are provided on the outer periphery of the rotary plate main body R1b. The operation key R1k and the spring support portion 212 are extended at positions that are substantially opposite each other across the rotary plate main body R1b.

[0016] The rotary plate case R1c is a round-plate-shaped part made up of a bottom plate portion 233 having the same shape and size as the rotary plate main body R1b, and a peripheral wall portion 232 provided along the outer periphery of the bottom plate portion 233. The bottom plate portion 233 is provided at its center with a convex portion 231 on its outer periphery to which the inner periphery of the bearing 220 can be joined without any gaps. Furthermore, a plurality of sound holes h3 are regularly arranged in the bottom plate portion 233. These sound holes h3 are arranged at the same positions and with the same size as the sound holes h1 in the upper air guide plate 150.

[0017] The rotating plate main body R1b ​​is housed in the rotating plate case R1c for use, and a bearing 220 is joined without gaps to the protrusion 231 of the rotating plate case R1c, and the shaft hole 211 of the rotating plate main body R1b ​​is joined without gaps to this bearing 220. The rotary plate case R1c is fixed by a fixing rod 104. Therefore, the rotary plate main body R1b ​​can rotate horizontally around the central portion as an axis while housed in the rotary plate case R1c.

[0018] The peripheral wall portion 232 of the rotary plate case R1c has a notch 232a cut out from both the inner wall and the outer wall at a position corresponding to the operation key R1k when the rotary plate main body R1b ​​is housed therein. This allows the rotary plate main body R1b ​​to be housed in the rotary plate case R1c with the support portion of the operation key R1k housed in the notch portion 232a. The cutout portion 232a is cut out over a length corresponding to a rotation angle of 15 degrees of the rotary plate main body R1b. This allows the rotary plate main body R1b ​​to rotate up to 15 degrees while housed in the rotary plate case R1c. FIG. 6(a) is an external perspective view of the first right rotating plate R1 in a non-rotating state, and FIG. 6(b) is an external perspective view of the first right rotating plate R1 in a rotating state. FIG. 6(b) shows the state when the first right rotating plate R1 shown in FIG. 6(a) is rotated 15 degrees counterclockwise. When the rotating plate main body R1b ​​rotates counterclockwise in response to the ON operation, the spring support portion 212 rotates accordingly, and as a result, the other end side of the compression spring 240 is compressed while receiving pressure from the peripheral wall portion 232. In other words, in response to the ON operation, the compression spring 240 is compressed while accumulating a repulsive force. Therefore, when the force applied by the fingers during the on operation is released (off operation), the repulsive force of the compression spring 240 is released in the extension direction, and this repulsive force returns the rotating plate body R1b ​​to a non-rotating state. That is, by turning off the first right rotating plate R1 in the rotating state shown in FIG. 6(b), it can be semi-automatically returned to the non-rotating state shown in FIG. 6(a). Although the first right rotating plate R1 has been described as an example, the second to fourth right rotating plates R2 to R4 and the first to third left rotating plates L1 to L3 have substantially the same configuration. Specifically, the second to fourth right rotating plates R2 to R4 differ from the first right rotating plate R1 only in the rotation direction and the position of the operation keys, and the first to third left rotating plates L1 to L3 differ from the first right rotating plate R1 only in the position of the operation keys. Therefore, detailed description of the second to fourth right rotating plates R2 to R4 and the first to third left rotating plates L1 to L3 will be omitted.

[0019] Each rotating plate is provided with an air leakage prevention structure to prevent air supplied to the inside of the rotating plate group 200 from leaking to the outside. Specifically, as shown in FIGS. 5 and 6, the peripheral wall 232 near the notch 232a is provided with a rail 232b, and the support portion (arcuate plate 213) of the operation key R1k is accommodated in this rail 232b. The arc-shaped plate 213 has a width greater than that of the notch 232a. In other words, the rotary plate main body R1b ​​is formed so as to cover the entire cutout portion 232a in any state, whether it is in a rotating state or a non-rotating state. This prevents the air supplied to the first right rotating plate R1 from leaking out through the notch 232a. By providing each rotating plate of the rotating plate group 200 with such an air leakage prevention structure, the air supplied to the rotating plate group 200 (first right rotating plate R1) can efficiently pass through only the connected sound hole h2 without leaking out to the outside.

[0020] The musical instrument 1 of the present invention is also provided with an air leakage prevention structure in addition to the above. For example, at the joint between the upper air guide plate 150 and the first right rotating plate R1, the joint between the first right rotating plate R1 and the second right rotating plate R2, the joint between the second right rotating plate R2 and the first left rotating plate L1, the joint between the first left rotating plate L1 and the third right rotating plate R3, the joint between the third right rotating plate R3 and the second left rotating plate L2, the joint between the second left rotating plate L2 and the fourth right rotating plate R4, the joint between the fourth right rotating plate R4 and the third left rotating plate L3, the joint between the third left rotating plate L3 and the reed section 300, the joint between the lower half-moon plate 340 of the reed section 300 and the lower air guide plate 350, and the joint between the lower air guide plate 350 and the resonance section 410, ring-shaped rubber packings are provided to prevent air from leaking out from around the plate surfaces.

[0021] (Regarding tone hole placement) The rules for arranging tone hole h2 will now be explained. As mentioned above, FIG. 7 is a plan view of each rotating plate in a non-rotating state, and FIG. 8 is a plan view of each rotating plate in a rotating state. That is, FIG. 7 shows the state of each rotary plate during normal operation or when the rotary plate is turned off, and FIG. 8 shows the state of each rotary plate during an on operation.

[0022] As shown in Figure 7(1), in the non-rotating state, the first right rotating plate R1 is configured so that sound holes h2 are arranged at the first to fourth positions around the circumference, corresponding to the 2 o'clock, 4 o'clock, 5 o'clock, 7 o'clock, 9 o'clock, 11 o'clock, and 12 o'clock positions, and sound holes h2 are not arranged at the 1 o'clock, 3 o'clock, 6 o'clock, 8 o'clock, and 10 o'clock positions.As shown in Figure 8(1), in the rotating state, sound holes h2 are arranged at the first to fourth positions around the circumference, corresponding to the 1 o'clock, 3 o'clock, 6 o'clock, 8 o'clock, and 10 o'clock positions, and sound holes h2 are not arranged at the 2 o'clock, 4 o'clock, 5 o'clock, 7 o'clock, 9 o'clock, 11 o'clock, and 12 o'clock positions. As shown in Figure 7 (2), when the second right rotating plate R2 is in a non-rotating state (when the plate is turned off), sound holes h2 are arranged at the first to fourth positions around the circumference, corresponding to the 2 o'clock, 3 o'clock, 4 o'clock, 7 o'clock, and 8 o'clock positions, and sound holes h2 are not arranged at the 1 o'clock, 5 o'clock, 6 o'clock, 9 o'clock, 10 o'clock, 11 o'clock, and 12 o'clock positions.As shown in Figure 8 (2), when the second right rotating plate R2 is in a rotating state (when the plate is turned on), sound holes h2 are arranged at the first to fourth positions around the circumference, corresponding to the 1 o'clock, 5 o'clock, 6 o'clock, 9 o'clock, 10 o'clock, 11 o'clock, and 12 o'clock positions, and sound holes h2 are not arranged at the 2 o'clock, 3 o'clock, 4 o'clock, 7 o'clock, and 8 o'clock positions. As shown in Figure 7 (3), in the non-rotating state, the third right rotating plate R3 is configured so that sound holes h2 are arranged at the first to fourth positions around the circumference, corresponding to the 1 o'clock, 4 o'clock, 9 o'clock, 10 o'clock, and 12 o'clock directions, and sound holes h2 are not arranged at the 2 o'clock, 3 o'clock, 5 o'clock, 6 o'clock, 7 o'clock, 8 o'clock, and 11 o'clock directions.As shown in Figure 8 (3), in the rotating state, sound holes h2 are arranged at the first to fourth positions around the circumference, corresponding to the 2 o'clock, 3 o'clock, 5 o'clock, 6 o'clock, 7 o'clock, 8 o'clock, and 11 o'clock directions, and sound holes h2 are not arranged at the 1 o'clock, 4 o'clock, 9 o'clock, 10 o'clock, and 12 o'clock directions. As shown in Figure 7 (4), in the non-rotating state, the fourth right rotating plate R4 is configured so that sound holes h2 are arranged at the first to fourth positions around the circumference, corresponding to the 1 o'clock, 2 o'clock, 3 o'clock, 5 o'clock, 6 o'clock, and 12 o'clock positions, and sound holes h2 are not arranged at the 4 o'clock, 7 o'clock, 8 o'clock, 9 o'clock, 10 o'clock, and 11 o'clock positions.As shown in Figure 8 (4), in the rotating state, sound holes h2 are arranged at the first to fourth positions around the circumference, corresponding to the 4 o'clock, 7 o'clock, 8 o'clock, 9 o'clock, 10 o'clock, and 11 o'clock positions, and sound holes h2 are not arranged at the 1 o'clock, 2 o'clock, 3 o'clock, 5 o'clock, 6 o'clock, and 12 o'clock positions.

[0023] As shown in Figure 7 (5), the first left rotating plate L1 is configured so that, in a non-rotating state, sound holes h2 are arranged at the first to third positions of all azimuths from 1 o'clock to 12 o'clock, and sound holes h2 are not arranged at the fourth position of the azimuth, and as shown in Figure 8 (5), in a rotating state, sound holes h2 are arranged at the fourth position of all azimuths from 1 o'clock to 12 o'clock, and sound holes h2 are not arranged at the first to third positions of the azimuth. As shown in Figure 7(6), the second left rotating plate L2 is configured so that, in a non-rotating state, sound holes h2 are located at the first, second, and fourth positions of all azimuths from 1 o'clock to 12 o'clock, and sound holes h2 are not located at the third position of the azimuth. As shown in Figure 8(6), in a rotating state, sound holes h2 are located at the third position of all azimuths from 1 o'clock to 12 o'clock, and sound holes h2 are not located at the first, second, and fourth positions of the azimuth. As shown in Figure 7 (7), the third left rotating plate L3 is configured so that, in a non-rotating state, sound holes h2 are arranged at the second to fourth positions of all azimuths from 1 o'clock to 12 o'clock, and sound holes h2 are not arranged at the first position of the azimuth. As shown in Figure 8 (7), in a rotating state, sound holes h2 are arranged at the first position of all azimuths from 1 o'clock to 12 o'clock, and sound holes h2 are not arranged at the second to fourth positions of the azimuth. In this way, the sound holes h2 are arranged along the rotation direction and the radial direction of the rotary plate. Here, the "rotation direction" corresponds to the "angle with the rotation axis as the origin" in polar coordinates, and the "radiation direction" corresponds to the "distance from the origin" in polar coordinates. Sound hole h1 and sound holes h2 to h7, which will be described later, are also arranged in a similar manner.

[0024] By arranging the tone holes h2 based on such polar coordinates, one specific tone hole h2 can be overlapped across all of the rotating plates by rotating any one or more of the seven rotating plates. For example, when only the second right rotating plate R2 is rotated, the sound holes h2 are located at the first to fourth positions around the second right rotating plate R2, in the 1 o'clock, 5 o'clock, 6 o'clock, 9 o'clock, 10 o'clock, 11 o'clock, and 12 o'clock directions. Since the first right rotating plate R1, the third right rotating plate R3, and the fourth right rotating plate R4 do not rotate, for the first right rotating plate R1, the sound holes h2 are located at the first to fourth positions around the circumference, at the 2 o'clock, 4 o'clock, 5 o'clock, 7 o'clock, 9 o'clock, 11 o'clock, and 12 o'clock positions; for the third right rotating plate R3, the sound holes h2 are located at the 1 o'clock, 4 o'clock, 9 o'clock, 10 o'clock, and 12 o'clock positions; and for the fourth right rotating plate R4, the sound holes h2 are located at the 1 o'clock, 2 o'clock, 3 o'clock, 5 o'clock, 6 o'clock, and 12 o'clock positions. Since the first to third left rotating plates L1 to L3 are not rotated, the first left rotating plate L1 has sound holes h2 located at the first to third positions of all azimuths from 1 o'clock to 12 o'clock, the second left rotating plate L2 has sound holes h2 located at the first, second and fourth positions of all azimuths from 1 o'clock to 12 o'clock, and the third left rotating plate L3 has sound holes h2 located at the second to fourth positions of all azimuths from 1 o'clock to 12 o'clock. As a result, in the rotary plate group 200, as shown in FIG. 9(a), only the sound holes h2 located on the second circumference in the 12 o'clock direction overlap and communicate with each other. In Figure 9, the white sound holes h2 indicate that the sound holes h2 of all the rotating plates are connected together, while the sound holes h2 shaded in light ink indicate that they are blocked by the surface of one of the rotating plates. That is, when the second right rotary plate R2 is turned on, the sound hole h1 of the upper air guide plate 150 arranged at "12 o'clock, second circumference" and the sound hole h2 of all the rotary plates are connected.

[0025] Furthermore, for example, when the first right rotating plate R1 and the second right rotating plate R2 are rotated, the sound holes h2 are arranged at the first to fourth positions around the circumference of the first right rotating plate R1, which are at the 1 o'clock, 3 o'clock, 6 o'clock, 8 o'clock, and 10 o'clock directions, and the sound holes h2 are arranged at the first to fourth positions around the circumference of the second right rotating plate R2, which are at the 1 o'clock, 5 o'clock, 6 o'clock, 9 o'clock, 10 o'clock, 11 o'clock, and 12 o'clock directions. Since the third right rotating plate R3 and the fourth right rotating plate R4 are not rotated, the sound holes h2 are located at the 1 o'clock, 4 o'clock, 9 o'clock, 10 o'clock, and 12 o'clock positions for the third right rotating plate R3, and the sound holes h2 are located at the 1 o'clock, 2 o'clock, 3 o'clock, 5 o'clock, 6 o'clock, and 12 o'clock positions for the fourth right rotating plate R4. Since the first to third left rotating plates L1 to L3 are not rotated, the first left rotating plate L1 has sound holes h2 located at the first to third positions of all azimuths from 1 o'clock to 12 o'clock, the second left rotating plate L2 has sound holes h2 located at the first, second and fourth positions of all azimuths from 1 o'clock to 12 o'clock, and the third left rotating plate L3 has sound holes h2 located at the second to fourth positions of all azimuths from 1 o'clock to 12 o'clock. As a result, in the rotary plate group 200, as shown in FIG. 9(b), only the sound hole h2 (white hole) located on the second circumference at the 1 o'clock azimuth overlaps and communicates. In other words, when the first right rotating plate R1 and the second right rotating plate R2 are turned on, the sound hole h1 of the upper air guide plate 150 located at the "1 o'clock to 2nd circumference" and the sound hole h2 of all the rotating plates are connected.

[0026] Furthermore, for example, when the first right rotating plate R1, the second right rotating plate R2, and the first left rotating plate L1 are rotated, the sound holes h2 are arranged at the first to fourth positions of the circumference of the first right rotating plate R1, at the 1 o'clock, 3 o'clock, 6 o'clock, 8 o'clock, and 10 o'clock directions, the sound holes h2 are arranged at the first to fourth positions of the circumference of the second right rotating plate R2, at the 1 o'clock, 5 o'clock, 6 o'clock, 9 o'clock, 10 o'clock, 11 o'clock, and 12 o'clock directions, and the sound holes h2 are arranged at the fourth positions of the circumference of the first left rotating plate L1, at all positions of the circumference .... Since the third right rotating plate R3 and the fourth right rotating plate R4 are not rotated, the sound holes h2 are located at the 1 o'clock, 4 o'clock, 9 o'clock, 10 o'clock, and 12 o'clock positions for the third right rotating plate R3, and the sound holes h2 are located at the 1 o'clock, 2 o'clock, 3 o'clock, 5 o'clock, 6 o'clock, and 12 o'clock positions for the fourth right rotating plate R4. Since the second left rotating plate L2 and the third left rotating plate L3 are not rotated, the sound holes h2 are located at the first, second and fourth positions of all azimuths from 1 o'clock to 12 o'clock on the second left rotating plate L2, and the sound holes h2 are located at the second to fourth positions of all azimuths from 1 o'clock to 12 o'clock on the third left rotating plate L3. As a result, in the rotary plate group 200, as shown in FIG. 9(c), only the sound hole h2 (white hole) located on the fourth circumference at the 1 o'clock azimuth overlaps and communicates. In other words, when the first right rotating plate R1, the second right rotating plate R2, and the first left rotating plate L1 are turned on, the sound holes h1 of the upper air guide plate 150 located at the "1 o'clock to 4th lap" positions and the sound holes h2 of all the rotating plates are connected. In this way, the sound holes h2 are arranged so that only specific sound holes h2 are in communication with each other depending on which rotating plate is being rotated.

[0027] FIG. 10 is a bit code table showing the arrangement rules for such tone holes h2. The bit code table shown in Figure 10 is a matrix diagram that shows the relationship between the state of each rotating plate (rotated: 1 / non-rotated: 0) and the position (orientation and circumference) of the connected tone hole h2, and also shows the relationship between this data and the 12-tone scale and octave range. FIG. 10(a) is a bit code table showing the relationship between the rotation / non-rotation of the first to fourth right rotating plates R1 to R4 and the direction of the sound hole h2 that communicates with them. That is, in FIG. 10(a), "orientation" indicates the orientation of the sound hole h2 that communicates with the first to fourth right rotating plates R1 to R4 in the left column, corresponding to rotation (1) / non-rotation (0) (see FIG. 3(a)). As shown in FIG. 10(a), the direction of the communicating sound hole h2 is determined based on the rotation / non-rotation of the first to fourth right rotating plates R1 to R4.

[0028] More specifically, in the bit code table shown in FIG. 10(a), when the second right rotating plate R2 is rotated, the sound holes h2 communicate at the "12 o'clock" orientation, which corresponds to "R2=1, R3=0, R4=0, R1=0." When the second right rotating plate R2 and the first right rotating plate R1 are rotated, the sound holes h2 communicate at the "1 o'clock" orientation, which corresponds to "R2=1, R3=0, R4=0, R1=1." When the third right rotating plate R3 is rotated, the sound holes h2 communicate at the "2 o'clock" orientation, which corresponds to "R2=0, R3=1, R4=0, R1=0." When the third right rotating plate R3 and the first right rotating plate R1 are rotated, the sound holes h2 communicate at the "3 o'clock" orientation, which corresponds to "R2=0, R3=1, R4=0, R1=1." When the fourth right rotating plate R4 is rotated, the sound holes h2 communicate at the "4 o'clock" orientation, which corresponds to "R2=0, R3=0, R4=1, R1=0." When the second right rotating plate R2 and the third right rotating plate R3 are rotated, the sound holes h2 communicate at the "5 o'clock" orientation, which corresponds to "R2=1, R3=1, R4=0, R1=0." When the second right rotating plate R2, the third right rotating plate R3 and the first right rotating plate When the third right rotating plate R3 and the fourth right rotating plate R4 are rotated, the sound hole h2 communicates at the "6 o'clock" orientation, which corresponds to "R2=1, R3=1, R4=0, R1=1." When the third right rotating plate R3 and the fourth right rotating plate R4 are rotated, the sound hole h2 communicates at the "7 o'clock" orientation, which corresponds to "R2=0, R3=1, R4=1, R1=0." When the third right rotating plate R3, the fourth right rotating plate R4, and the first right rotating plate R1 are rotated, the sound hole h2 communicates at the "8 o'clock" orientation, which corresponds to "R2=0, R3=1, R4=1, R1=1." When the second right rotating plate R2, the fourth right rotating plate R4, and the first right rotating plate R1 are rotated, the sound holes h2 are connected at the "9 o'clock" orientation, which corresponds to "R2=1, R3=0, R4=1, R1=0." When the second right rotating plate R2, the fourth right rotating plate R4, and the first right rotating plate R1 are rotated, the sound holes h2 are connected at the "10 o'clock" orientation, which corresponds to "R2=1, R3=0, R4=1, R1=1." When the second right rotating plate R2, the third right rotating plate R3, and the fourth right rotating plate R4 are rotated, the sound holes h2 are connected at the "11 o'clock" orientation, which corresponds to "R2=1, R3=1, R4=1, R1=0." Furthermore, when none of the first to fourth right rotating plates R1 to R4 are rotated, the sound hole h2 is not connected in any direction of the first to fourth right rotating plates R1 to R4, which corresponds to "none" (R2=0, R3=0, R4=0, R1=0).

[0029] FIG. 10(b) is a bit code table showing the relationship between the rotation / non-rotation of the first to third left rotating plates L1 to L3 and the circumference of the sound hole h2 with which they communicate. In other words, the "circumference" shown in Figure 10(b) indicates the radial position (any of the first to fourth circumferences) of the sound hole h2 that communicates with the first to third left rotating plates L1 to L3 in the left column, with rotation: 1 / non-rotation: 0. As shown in FIG. 10(b), the position in the radiation direction of the communicating sound hole h2 is determined based on the rotation / non-rotation of the first to third left rotating plates L1 to L3.

[0030] More specifically, in the bit code table shown in FIG. 10(b), when none of the first to third left rotating plates L1 to L3 are rotated, the sound holes h2 of the "second circle" corresponding to "L1=0, L2=0, L3=0" are connected; when the first left rotating plate L1 is rotated, the sound holes h2 of the "fourth circle" corresponding to "L1=1, L2=0, L3=0" are connected; when the second left rotating plate L2 is rotated, the sound holes h2 of the "third circle" corresponding to "L1=0, L2=1, L3=0" are connected; and when the third left rotating plate L3 is rotated, the sound holes h2 of the "first circle" corresponding to "L1=0, L2=0, L3=1" are connected.

[0031] According to this bit code table, if, for example, only the second right rotating plate R2 is rotated among the seven rotating plates, the position of the communicating tone hole h2 will be "12 o'clock, second circle" (see Figure 9(a)) as shown in Figures 10(a) and (b). Furthermore, when the first right rotating plate R1 and the second right rotating plate R2 are rotated, referring to Figures 10(a) and (b), the position of the communicating sound hole h2 becomes "1 o'clock - 2nd rotation" (see Figure 9(b)). Furthermore, when the first right rotating plate R1, the second right rotating plate R2, and the first left rotating plate L1 are rotated, referring to Figures 10(a) and (b), the position of the communicating sound hole h2 is "1 o'clock to 4 o'clock" (see Figure 9(c)). In this way, the sound holes h2 are arranged so that specific sound holes h2 are connected at specific positions (orientations and circumferences) based on the rotation / non-rotation of the first to fourth right rotating plates R1 to R4 and the first to third left rotating plates L1 to L3, and the bit code table covers all of these relationships.

[0032] In this way, the musical instrument 1 of the present invention is provided with a group of rotating plates 200 in which a plurality of rotating plates each having a plurality of tone holes (tone hole h2) are stacked one on top of the other, and specific tone holes can be connected across the plurality of rotating plates in accordance with the rotation of the rotating plates. Specifically, the multiple sound holes are arranged along the rotational and radial directions of the rotating plate, and are arranged so that specific sound holes are connected based on the rotation / non-rotation of one or more rotating plates, and sound holes other than the specific sound holes are blocked. As a result, when breath (air) is blown into the interior through the mouthpiece 101 while the rotating plate is rotating, the air passes through the blowing section 100, and further passes through specific sound holes (sound holes h1, h2, h3) that are connected to the upper air guide plate 150 and the rotating plate group 200, and is supplied to the corresponding sound hole (half-moon sound hole h4) in the reed section 300.

[0033] (Lead part) The lead portion 300 is a component that is provided below the rotating plate group 200 and corresponds to the oscillator portion of the present invention (FIGS. 1 and 2). FIG. 11 is an exploded perspective view of the lead portion 300. As shown in FIG. As shown in FIG. 11, the lead portion 300 is mainly composed of an upper half-moon plate 310 , twelve lead plates 320 , a lead plate fixing portion 330 , a lower half-moon plate 340 , and a lower air guide plate 350 .

[0034] FIG. 12( a ) is a plan view of the upper meniscus 310 . FIG. 12(b) is a plan view of the lead-plate fixing portion 330. FIG. FIG. 12( c ) is a plan view of the lower meniscus 340 . As shown in FIGS. 12(a) and 12(c), the upper half-moon plate 310 and the lower half-moon plate 340 are disk-shaped parts, similar to the upper air guide plate 150, the lower air guide plate 350, and the rotary plates R1 to R4, L1 to L3. The upper and lower meniscus plates 310 and 340 are provided with semicircular half-moon sound holes h4 and h6 at the first to fourth positions around the circumference in the 1 o'clock to 12 o'clock directions, respectively. The meniscus sound hole h4 of the upper meniscus 310 and the meniscus sound hole h6 of the lower meniscus 340 are formed in symmetrical shapes. As can be seen by comparing Figures 12(a) and 12(c), for example, the 12 o'clock semilunar sound hole h4 of the upper meniscus 310 is formed by drilling a right semicircle, while the 12 o'clock semilunar sound hole h6 of the lower meniscus 340 is formed by drilling a left semicircle. Lead plate fixing portion 330 is a cylindrical member, and upper meniscus 310 is joined to the upper part, and lower meniscus 340 is joined to the lower part (FIG. 11). 3, 11, 12(b), etc., the lead plate fixing portion 330 has a cylindrical sound hole h5 at the same position as the sound holes h1, h7 of the upper and lower air guide plates 150, 350. In other words, the cylindrical sound holes h5 are provided at the points where the radial lines from 1 o'clock to 12 o'clock intersect with the circumferential lines of the first to fourth circles. Each cylindrical sound hole h5 has a slit formed along the center line in the radial direction, and one reed plate 320 is inserted into this slit and fixed in place. The lead plate 320 is a plate-shaped member made of brass. As shown in FIG. 11 and other figures, the twelve reed plates 320 are formed to the same thickness, and are fixed inside the corresponding cylindrical tone holes h5 at 1 to 12 o'clock.

[0035] FIG. 13 is a front view of the twelve lead plates 320. As shown in FIG. Fig. 13(1) is a reed plate 32C equipped with a reed (oscillating means) capable of oscillating the scale C (do), Fig. 13(2) is a reed plate 32C# equipped with a reed capable of oscillating the scale C# (do#), Fig. 13(3) is a reed plate 32D equipped with a reed capable of oscillating the scale D (re), Fig. 13(4) is a reed plate 32D# equipped with a reed capable of oscillating the scale D# (re#), Fig. 13(5) is a reed plate 32E equipped with a reed capable of oscillating the scale E (mi), Fig. 13(6) is a reed plate 32F equipped with a reed capable of oscillating the scale F (fa), Figure 13(7) is a reed board 32F# with a reed that can oscillate the F# scale, Figure 13(8) is a reed board 32G with a reed that can oscillate the G# scale, Figure 13(9) is a reed board 32G# with a reed that can oscillate the G# scale, Figure 13(10) is a reed board 32A with a reed that can oscillate the A# scale, Figure 13(11) is a reed board 32A# with a reed that can oscillate the A# scale, and Figure 13(12) is a reed board 32B with a reed that can oscillate the B# scale.

[0036] The lead plates 320 are fixed at the 1 o'clock to 12 o'clock orientations, respectively. Reed plate 32C is provided across four cylindrical sound holes h5 located at the 12 o'clock position, reed plate 32C# is provided across four cylindrical sound holes h5 located at the 1 o'clock position, reed plate 32D is provided across four cylindrical sound holes h5 located at the 2 o'clock position, reed plate 32D# is provided across cylindrical sound holes h5 located at the 3 o'clock position, reed plate 32E is provided across four cylindrical sound holes h5 located at the 4 o'clock position, reed plate 32F is provided across four cylindrical sound holes h5 located at the 5 o'clock position, reed plate 32F# is provided over the four cylindrical sound holes h5 located at the 6 o'clock position, reed plate 32G is provided over the four cylindrical sound holes h5 located at the 7 o'clock position, reed plate 32G# is provided over the four cylindrical sound holes h5 located at the 8 o'clock position, reed plate 32A is provided over the four cylindrical sound holes h5 located at the 9 o'clock position, reed plate 32A# is provided over the four cylindrical sound holes h5 located at the 10 o'clock position, and reed plate 32B is provided over the four cylindrical sound holes h5 located at the 11 o'clock position (see FIG. 12(b)).

[0037] FIG. 14 is a perspective view showing a partial cross section of the lead plate 320. As shown in FIG. As shown in FIGS. 12 to 14, the lead plate 320 is provided with four leads (hereinafter also referred to as first to fourth leads 321 to 324) as oscillation means. The first to fourth leads 321 to 324 are formed in a rectangular shape, with their upper portions connected to the lead plate 320 and their lower and both side portions fixed to the lead plate 320 with a small gap therebetween. Therefore, when air flows from one side of lead plate 320 to the other side, first to fourth reeds 321 to 324 oscillate like a pendulum with their upper parts as a fulcrum as the air passes through the gaps along the flow (air path). Each reed plate 320 and reeds 321 to 324 has a vibration frequency set according to its weight, and when it oscillates, it produces a sound of a scale (12 notes or a range of multiple octaves) corresponding to the vibration of that frequency. The weights of the reed plate 320 and the reeds 321 to 324 are changed based on their lengths and widths, and therefore the reeds oscillate at different frequencies, which in turn produce different musical scales.

[0038] Specifically, the first to fourth leads 321 to 324 have the same thickness and length, but have a width relationship of first lead 321>second lead 322>third lead 323>fourth lead 324 (see FIG. 13). For example, in lead plate 32C, first to fourth leads 321 to 324 are all formed with a length of approximately 14 mm, but first lead 321 has a width of approximately 7.2 mm, second lead 322 has a width of approximately 3.6 mm which is half the width of first lead 321, third lead 323 has a width of approximately 1.8 mm which is half the width of second lead 322, and fourth lead 324 has a width of 0.9 mm which is half the width of third lead 323. In this way, by keeping the thickness and length of the reeds the same while halving (doubles) the width, theoretically the frequency at which the reeds vibrate can be halved (doubled). For example, in reed plate 32C, first reed 321 can be vibrated at a first frequency to produce a C note (fundamental tone) in the low range (first octave), second reed 322 can be vibrated at a second frequency that is twice the first frequency to produce a C note (second harmonic) in the high range (second octave) higher than the first octave, third reed 323 can be vibrated at a third frequency that is twice the second frequency to produce a C note (third harmonic) in the high range (third octave) higher than the second octave, and fourth reed 324 can be vibrated at a fourth frequency that is twice the third frequency to produce a C note (fourth harmonic) in the high range (fourth octave) higher than the third octave. The other reed plates 32C#, 32D, 32D#, 32E, 32F, 32F#, 32G, 32G#, 32A, 32A#, and 32B are similar to reed plate 32C, and the first reed 321 can oscillate the fundamental tone of the corresponding scale, the second reed 322 can oscillate the harmonic tone of the corresponding scale, the third reed 323 can oscillate the third harmonic tone of the corresponding scale, and the fourth reed 324 can oscillate the fourth harmonic tone of the corresponding scale.

[0039] Furthermore, the lead plates 320 have different lead lengths. For example, the lead of lead plate 32C is approximately 14 mm long, the lead of lead plate 32C# is approximately 13.5 mm long, the lead of lead plate 32D is approximately 13 mm long, the lead of lead plate 32D# is approximately 12.5 mm long, the lead of lead plate 32E is approximately 12 mm long, the lead of lead plate 32F is approximately 11.5 mm long, the lead of lead plate 32F# is approximately 11 mm long, the lead of lead plate 32G is approximately 10.5 mm long, the lead of lead plate 32G# is approximately 10 mm long, the lead of lead plate 32A is approximately 9.5 mm long, the lead of lead plate 32A# is approximately 9 mm long, and the lead of lead plate 32B is approximately 8.5 mm long (see FIG. 13). In other words, the lengths of adjacent notes are made to differ at equal intervals.

[0040] By doing so, the first reed 321 of reed plate 32C can oscillate the fundamental note of the C scale (the note of the first octave), the first reed 321 of reed plate 32C# can oscillate the fundamental note of the C# scale, the first reed 321 of reed plate 32D can oscillate the fundamental note of the D scale, the first reed 321 of reed plate 32D# can oscillate the fundamental note of the D# scale, the first reed 321 of reed plate 32E can oscillate the fundamental note of the E scale, and the first reed 321 of reed plate 32F can oscillate the fundamental note of the F scale. The first reed 321 of reed plate 32F# can oscillate the fundamental note of the F# scale, the first reed 321 of reed plate 32G can oscillate the fundamental note of the G# scale, the first reed 321 of reed plate 32G# can oscillate the fundamental note of the G# scale, the first reed 321 of reed plate 32A can oscillate the fundamental note of the A# scale, the first reed 321 of reed plate 32A# can oscillate the fundamental note of the A# scale, and the first reed 321 of reed plate 32B can oscillate the fundamental note of the B# scale.

[0041] The second to fourth leads 322 to 324 are similar to the first lead 321. That is, the second to fourth reeds 322 to 324 of the reed plate 32C can oscillate the overtones (sounds of the second octave), the third overtone (sounds of the third octave), and the fourth overtone (sounds of the fourth octave) of the scale C (do), and the second to fourth reeds 322 to 324 of the reed plate 32C# can oscillate the overtones, the third overtone, and the fourth overtone of the scale C# (do#), and the second to fourth reeds 322 to 324 of the reed plate 32D can oscillate the overtones, the third overtone, and the fourth overtone of the scale C# (do#). The overtones, third and fourth harmonics of the D scale can be generated, and the second to fourth reeds 322 to 324 of the reed plate 32D# can generate the overtones, third and fourth harmonics of the D scale. The second to fourth reeds 322 to 324 of the reed plate 32E can generate the overtones, third and fourth harmonics of the E scale. The second to fourth reeds 322 to 324 of the reed plate 32F can generate the overtones, third and fourth harmonics of the F scale. The second through fourth reeds 322 through 324 of the reed plate 32F# can oscillate the overtone, third overtone, and fourth overtone of the scale F# (Fa#). The second through fourth reeds 322 through 324 of the reed plate 32G can oscillate the overtone, third overtone, and fourth overtone of the scale G (So). The second through fourth reeds 322 through 324 of the reed plate 32G# can oscillate the overtone, third overtone, and fourth overtone of the scale G# (So#). The second through fourth reeds 322 through 324 of reed plate 32A can vibrate to produce the overtones, third overtones, and fourth overtones of the scale A (La), the second through fourth reeds 322 through 324 of reed plate 32A# can vibrate to produce the overtones, third overtones, and fourth overtones of the scale A# (La#), and the second through fourth reeds 322 through 324 of reed plate 32B can vibrate to produce the overtones, third overtones, and fourth overtones of the scale B (Si).

[0042] That is, the reed plates are provided to correspond to different musical scales, and the reeds are capable of oscillating different musical scales and octave ranges depending on the width and length of the reed. In this embodiment, the reed plates 320 have the same thickness but different widths and lengths to change the scale of each reed, but instead of or in addition to this, weights can also be applied as an adjustment factor for the scale. In fact, the reed of this embodiment has a thickened lower end and a recessed portion; if you want to increase the weight, you can add a metal such as lead by spraying it into the recessed portion; if you want to decrease the weight, you can adjust the weight by shaving off the thick portion, allowing for accurate tuning (see Figure 14).

[0043] In the lead portion 300 having such a configuration, when air is supplied from above, the air passes through the inside of the lead portion 300 and forms an air passage. For example, a case will be described in which air is blown into the mouthpiece 101 when the second right rotating plate R2 is rotated, that is, when the 12 o'clock and second circumferential tone holes h2 are in communication. In this case, the air passes through the blowing pipe 102, then passes through the sound hole h1 located at 12 o'clock and the second circumference of the upper air guide plate 150, and further passes through the sound holes (sound holes h2 and h3) located at 12 o'clock and the second circumference of the rotating plate group 200, and is thereby guided (introduced) to the reed portion 300.In this case, air is supplied to the semicircular sound hole h4 located at 12 o'clock and the second circumference of the upper semicircular plate 310.

[0044] Fig. 15 is a cross-sectional view taken along the line AA in Fig. 12(a) , that is, Fig. 15 is a cross-sectional view of the tone holes (h4, h5, h6, h7) located at 12 o'clock and the second circumference of the reed portion 300. In Figure 15, the upper half-moon plate 310, lead plate fixing portion 330, lower half-moon plate 340, lower air guide plate 350, and other components are shown stacked with gaps between them, but this is just an illustration to make the explanation easier to understand; in reality, they are stacked without any gaps to prevent air leakage. As shown in FIG. 15, when air is supplied from above to the crescent sound hole h4 at 12 o'clock and the second circumference of the upper meniscus 310, the air passes through the crescent sound hole h4 and is supplied to the cylindrical sound hole h5 at 12 o'clock and the second circumference (arrow a). Air travels downward through the cylindrical sound hole h5, but because the crescent sound hole h6 of the lower meniscus 340, which is located below the cylindrical sound hole h5, is provided on the left side, air travels downward and left (arrow b). This air vibrates (oscillates) the second reed 322 of the reed plate 32C provided at 12 o'clock and the second circumference at a predetermined frequency, thereby producing the sound of the C scale of the second octave. The sound emitted by the oscillation of the reed 322 passes through the half-moon sound hole h6 and the sound hole h7 of the lower air guide plate 350 (arrow c). As a result, the sound is supplied to the sound output unit 400. The reed part 300 has a cylindrical cavity 390 in the center, which also has the function of resonating sound together with a resonating part 410, which will be described later.

[0045] (Sound part) Sound output section 400 is a component provided below reed section 300, and is composed of resonance section 410 and bell section 420 (FIGS. 1 and 2). Resonator 410 is a cylindrical part with a circular opening 411 at the center of the bottom. In such a resonating portion 410, the sound output from the reed portion 300 can be resonated and amplified. The sound amplified by resonance section 410 is output to bell section 420 via opening 411 . Bell section 420 is provided below resonance section 410 and at the lowest part of musical instrument 1. Bell portion 420 is curved so that the end opening surface faces forward, and is expanded in a bell or trumpet shape. By providing such bell portion 420, the sound amplified by resonance portion 410 can be output widely forward. This allows many people to clearly hear the sound and performance of Instrument 1.

[0046] In the musical instrument 1 configured as described above, when air is blown into the mouthpiece 101 while the rotating plate is rotating, the air passes through the blowing section 100, and then passes through specific sound holes (sound holes h1 and h2) that are connected to the upper air guide plate 150 and the rotating plate group 200, and is supplied to the reed section 300 below. In the reed portion 300, air supplied from above passes through the interior, causing the reed plates 320 provided in the sound holes through which the air passes to vibrate (oscillate). For example, as in the example described above, when the second right rotating plate R2 is rotated, that is, when the 12 o'clock / 2nd circle tone holes h2 are connected, and air is blown into the mouthpiece 101, the air is supplied to the 12 o'clock / 2nd circle crescent tone hole h4 of the upper crescent plate 310, and then passes through the 12 o'clock / 2nd circle cylindrical tone hole h5 of the reed plate fixing part 330. As the air passes, the second reed 322 of the reed plate 32C fixed at the 12 o'clock / 2nd circle position vibrates (oscillates), and the sound of C of the second octave is emitted and output to the outside via the sound output part 400 (see Figures 10 to 13, etc.). Furthermore, when the first right rotating plate R1 and the second right rotating plate R2 are rotated, that is, when the 1 o'clock and 2nd round tone holes h2 are connected, and air is blown into the mouthpiece 101, the air is supplied to the 1 o'clock and 2nd round semicircular tone holes h4 of the upper semicircular plate 310, and then passes through the 1 o'clock and 2nd round cylindrical tone holes h5 of the reed plate fixing part 330. As the air passes through, the second reed 322 of the reed plate 32C# fixed at the 1 o'clock and 2nd round position vibrates (oscillates), and the sound of C# of the second octave is emitted and output to the outside via the sound output part 400 (see Figures 10 to 13, etc.). Furthermore, when the first right rotating plate R1, the second right rotating plate R2, and the first left rotating plate L1 are rotated, that is, when the 1 o'clock and 4th round tone holes h2 are connected, and air is blown into the mouthpiece 101, the air is supplied to the 1 o'clock and 4th round semicircular sound holes h4 in the upper semicircular plate 310, and then passes through the 1 o'clock and 4th round cylindrical sound holes h5 in the reed plate fixing part 330. As the air passes through, the fourth reed 324 of the C# reed plate 32 fixed at the 1 o'clock and 4th round position vibrates (oscillates), and the sound of C# in the fourth octave is produced and output to the outside via the sound output part 400 (see FIGS. 10 to 13, etc.). The relationship between the rotation of each rotary plate and the scale and octave range that are generated is all defined in a bit code table (Fig. 10), and the tone holes h2 are arranged according to this bit code table. In short, the seven diatonic scales of C (Do), D (Re), E (Mi), F (Fa), G (So), A (La), and B (Ti) are realized based on the combination of rotating / non-rotating (1 / 0) of the second to fourth right rotating plates R2 to R4. In addition, the five chromatic scales of C# (Do#), D# (Re#), F# (Fa#), G# (So#), and A# (La#) are realized based on the rotation / non-rotation combinations of the first right rotating plate R1 in addition to the rotation / non-rotation combinations of the second to fourth right rotating plates R2 to R4. Therefore, with the instrument 1, the player can produce the desired sound for the 12 notes contained in the one-octave range by operating the first to fourth right rotating plates R1 to R4 to rotate or not rotate. The first to fourth octave scales are realized based on the combination of rotation / non-rotation of the first to third left rotating plates L1 to L3. Therefore, with the instrument 1, the player can produce the desired sound for all scales included in the four-octave range by operating the first to fourth right rotating plates R1 to R4 and the first to third left rotating plates L1 to L3 to rotate / non-rotate. Furthermore, if none of the first to fourth right rotating plates R1 to R4 and the first to third left rotating plates L1 to L3 are rotated, no oscillation occurs because there is no communicating sound hole h2 for supplying air to vibrate the reed (see Figure 10). In this way, in the musical instrument 1 of the present invention, based on a bit code system employing binary numbers of "1" / "0" corresponding to the rotation / non-rotation of the rotating plate, 12 scales are set along the circumference (direction of rotation), and the 12 scales are set separately on multiple circumferences, thereby realizing the oscillation of scales over a wide octave range with a simple configuration and easy operation.

[0047] In this way, the musical instrument 1 of this embodiment uses seven rotating plates, and can play up to two 7=128 rotation / non-rotation combinations provide a wide range of sound variations. Specifically, in the three rotating plates, the second to fourth right rotating plates R2 to R4, 3 A bit code system is defined that corresponds the eight whole notes Do, Re, Mi, Fa, So, La, Si, and Do to the eight possible combinations of rotating / non-rotating wheels, allowing the user to select the desired scale from among these. In addition, by adding the first right rotating plate R1, there are four rotating plates, 4 A bit code system is defined that corresponds 12 of the 16 combinations of rotating / non-rotating wheels to 12 of the 16 combinations of rotating / non-rotating wheels, with 12 whole tones and semitones: Do, Do#, Re, Re#, Mi, Fa, Fa#, So, So#, La, La#, and Si, from which the desired scale can be selected. Furthermore, by adding three rotating plates, the first to third left rotating plates L1 to L3, a maximum of 2 3 = 8 rotation / non-rotation combinations are added, but for convenience of key operation, four combinations have been added: rotation of each left rotation plate and non-rotation of all left rotation plates. This defines a bit code system that corresponds to 12 x 4 = 48 different whole-tone and half-tone scales across a four-octave range, allowing the desired scale to be selected from among them. In other words, based on an unprecedented scale theory that focuses on the rotational direction and radial direction corresponding to polar coordinates, as well as the rotation axis direction, which is the number of rotating plates, we have achieved oscillation (sound production) over a wide range of several octaves while maintaining operability.

[0048] (Vibrato sound generation based on click operation) The instrument 1 has a mechanism that allows the second to fourth right rotating plates R2 to R4 to be clicked, and the scale can be easily vibrated (vibrato) based on the click operation. Specifically, each rotary plate can be rotated by 15 degrees, but the second to fourth right rotary plates R2 to R4 are provided with a click operation mechanism, so that rotation operations of less than 15 degrees can be easily performed. FIG. 16 is an exploded perspective view of the second right rotating plate R2. FIG. 17 is an enlarged plan view of the main part of FIG. As shown in these figures, the second right rotating plate R2 has an uneven portion S3 in which concave and convex portions are successively arranged in a wave-like pattern on a part of the outer periphery of the rotating plate main body R2b (for example, in the section between 11 o'clock and 12 o'clock). A recess 232d is provided in the peripheral wall 232 of the rotary plate case R2c at a location corresponding to the uneven portion S3, and one end of a compression spring S1 is fixed to the wall of the recess 232d. A ball S2 (e.g., an iron ball) is rotatably attached to the other end of the compression spring S1, and when the compression spring S1 is compressed, the spherical surface of the ball is in contact with the outer surface of the rotating plate main body R2b with a predetermined pressure. This allows the fingers to feel a slight vibration (click) each time the ball goes over an uneven portion during rotation. Therefore, the player can consciously rotate the rotating plate stepwise to any desired rotation angle based on the clicking sensation. For example, by repeating half and full rotations, the air flow rate to the reed plate 320 can be continuously changed or adjusted in several steps, thereby changing the vibration of the reeds 321 to 324 and generating a vibrato sound. Based on such a click operation of the second right rotating plate R2, vibrato can be produced for the notes C (do), C# (do#), F (fa), F# (fa#), A (la), A# (la#), and B (si) (see Figure 10). The third right rotating plate R3 and the fourth right rotating plate R4 are similar to the second right rotating plate R2. By clicking the third right rotating plate R3, vibrato can be produced for the notes D, D#, F, F#, G, G#, and B (see Figure 10). By clicking the fourth right rotating plate R4, vibrato can be produced for the notes E, G, G#, A, A#, and B (see Figure 10).

[0049] (Variation) The instrument 1 can produce chords by simultaneously emitting multiple sounds of different pitches. That is, in the above-described embodiment, only one tone hole h2 is connected based on the rotation of the rotary plate, and one corresponding scale is generated. However, if multiple tone holes h2 are connected based on the rotation of the rotary plate, multiple corresponding scales can be generated simultaneously. For example, if a rotating plate for chords is provided and the tone holes h2 are positioned so that the tone holes h2 at 12 o'clock, 4 o'clock, and 7 o'clock are connected when the rotating plate is operated, the three notes C (do), E (mi), and G (sol) can be emitted simultaneously. This allows the C-E-G chord to be produced by blowing air into the instrument 1 while the chord rotating plate is rotating. It is possible to produce chords other than C-Mi-So (for example, Re-Fa-La), and chords consisting of four or more notes can be produced in addition to triads. Also, one or more sound holes can be connected in response to key operation. This allows oscillation of one scale or simultaneous oscillation of multiple scales, making it possible to produce (sound) a desired single note or chord. It is to be noted that the device may have either a configuration capable of oscillating one scale or a configuration capable of simultaneously oscillating multiple scales, or may have both configurations. That is, the instrument 1 may be configured to be capable of producing only single tones, or may be configured to be capable of producing only chords, or may be configured to be capable of producing both single tones and chords.

[0050] As described above, the musical instrument 1 of the present invention comprises a plurality of rotating plates (R1-R4, L1-L3) each having a plurality of tone holes (tone hole h2) stacked on top of one another, and a rotating plate group 200 that can connect specific tone holes (tone hole h2) across the plurality of rotating plates in accordance with the rotation of the rotating plates, and an oscillator section (reed section 300) that oscillates based on air (airflow) that passes through the connected tone holes (tone hole h2), and the plurality of tone holes (tone hole h2) are arranged so that the specific tone hole (tone hole h2) changes depending on the rotating plate, and the oscillator section (reed section 300) has oscillator means (reeds) that can emit sounds of different musical scales at positions corresponding to the different tone holes (tone hole h2). In this way, the musical instrument 1 of the present invention can be realized with a simple configuration by simply stacking a plurality of rotating plates on which a plurality of tone holes h2 are arranged. In addition, sound holes h2 are provided along the rotational direction (corresponding to the angle shown in polar coordinates) and the radial direction (corresponding to the distance shown in polar coordinates), and the number of notes that can be generated can be increased simply by stacking multiple rotating plates, making it possible to achieve performances over a wide octave range with a simple configuration. Furthermore, the player can easily operate the instrument since all he or she has to do is rotate the rotary plate corresponding to the desired scale. In other words, the musical instrument 1 of the present invention has a simple structure that has not been seen in the past, and can be easily operated to perform a wide range of octaves. For example, with conventional saxophones, the maximum octave range is two octaves, depending on the reed attached to the mouthpiece and key operation, so to play across four octaves as in the present invention, four different saxophones are required. In contrast, the musical instrument 1 of the present invention allows a performance over four octaves to be easily performed simply by blowing air into the mouthpiece 101. Furthermore, the mouthpiece 101 does not have a reed, so it is simple, lightweight, and inexpensive. In the musical instrument 1 of the present invention, the oscillator (reed section 300) is capable of oscillating multiple scales, and the rotating plate group 200 includes rotating plates R2 to R4 corresponding to whole tones and rotating plate R1 corresponding to semitones. With such an instrument 1, if you want to play a melody consisting of whole tones, you only need to operate the rotary wheels (R2 to R4), and only when you need a semitone, you need to operate the semitone rotary wheel (R1) (see Figure 10), making it very convenient for playing. Furthermore, in the musical instrument 1 of the present invention, the oscillator section (reed section 300) is capable of oscillating in a range of multiple octaves, and the rotating plate group 200 includes a rotating plate (e.g., L3) corresponding to the first octave range and a rotating plate (e.g., L4) corresponding to multiple octaves, such as the second octave range. With such an instrument 1, for example, if you want to play notes or melodies in the first octave, you simply operate the third left rotating plate L3, and if you want to play notes or melodies in the third octave, you simply operate the second left rotating plate L2 (see Figure 10), which increases the convenience of playing while also increasing the variety of songs and melodies that can be played. In the musical instrument 1 of the present invention, the tone holes h2 are arranged so that the tone holes h2 arranged in specific rotational and radial directions communicate with each other based on the rotation of one or more rotary plates. In other words, a three-dimensional polar coordinate system is constructed by stacking multiple rotating plates in the axial direction, with sound holes h2 arranged according to the angle (rotation direction) and distance (radiation direction) shown in polar coordinates, and the musical instrument 1 of the present invention is constructed in the three-dimensional space represented by this three-dimensional polar coordinate system. Furthermore, in the musical instrument 1 of the present invention, the oscillation section (reed section 300) comprises a plurality of reed plates 320 each having a plurality of reeds 321-324 as oscillation means that can oscillate based on the vibration of air, and the reed plates 320 are provided corresponding to different musical scales, and the reeds 321-324 are capable of oscillating in different octave ranges depending on the width of the reed. In this way, the instrument 1 of the present invention provides a wind instrument that has a configuration that corresponds to a scale theory that has not been seen in the past, a wide range of notes covering several octaves, and ergonomic operability that is suited to the fingers.

[0051] The musical instrument 1 of the present invention has been described above by showing a preferred embodiment, but it goes without saying that the present invention is not limited to the above-described embodiment, and various modifications can be made within the scope of the present invention. For example, the mouthpiece 101 may be provided at the bottom of the instrument 1, and the sound output unit 400 may be provided at the top of the instrument 1. Furthermore, the number, shape, and size of the rotating plates, and the number, shape, size, and position of the sound holes are not limited to those in the above-described embodiment. For example, although 12 sound holes are provided along the direction of rotation, the number may be 11 or less, 13 or more, or even 24. Furthermore, although four sound holes are provided along the radiation direction, the number may be three or less or five or more. Although seven rotating plates are stacked in the above embodiment, the number of plates may be six or less or eight or more. The rotating plate relating to the musical scale or chromatic scale may be a left rotating plate, and the rotating plate relating to the octave range may be a right rotating plate. Although the above description has been given of a configuration including the rotary plates (R2 to R4) corresponding to whole tones and the rotary plate (R1) corresponding to half tones, the musical instrument 1 of the present invention may be configured with only rotary plates corresponding to whole tones. The direction of rotation of the rotating plate can also be changed. The rotation direction of the rotating plate can be set to either one direction or both directions. In this case, a bit code can be constructed based on three bits: right rotation, left rotation, and no rotation. The positions of the sound holes in the upper air guide plate 150, the reed portion 300, etc. (that is, the communication positions of the sound hole h2) do not have to be located at the 1 to 12 o'clock positions. For example, it is not necessary to arrange them at equal intervals of 30 degrees, but they may be arranged unevenly, and they are not limited to 12 locations, but may be 11 or less or 13 or more. Furthermore, the rotation angle (maximum) of the rotating plate is not limited to 15 degrees, but may be less than 15 degrees or more than 15 degrees. For example, by providing a first rotation with a rotation angle of 7.5 degrees and a second rotation with a rotation angle of 15 degrees, a bit code based on three bits: first rotation / second rotation / no rotation can be constructed. In the lead portion 300, four leads are integrally formed, but the number may be three or less, or five or more, or each lead may be independent and separate. The number of rotating plates, the number of sound holes, and the arrangement configuration may be combined in any manner. The size and thickness of the rotary plate and the position of the operation keys may be adjusted to suit the size and thickness of the fingers of the player (for example, a child). The width and length of the lead are not limited to the above values ​​and can be changed. The oscillation means is not limited to a reed, and may be any means that oscillates for each musical scale. Although a compression spring (240, S1) is used to return the rotating plate from a rotating state to a non-rotating state or in the click operation mechanism, this is not limitative and other elastic members such as a spiral spring or a leaf spring can also be used.
