Description

[Technical field]

[0001] The present invention relates to a chord generating method for selectively generating chords, and to a single note generating device and a chord generating device used therein. [Background technology]

[0002] Patent Document 1 describes a wind instrument that has multiple trumpet bodies, a connecting body that detachably bundles the mouthpieces of each trumpet body in a substantially horizontal line, and a communicating mouthpiece body that is connected to the connecting body and communicates with the mouthpieces of each trumpet body. According to the wind instrument of Patent Document 1, air is blown into the multiple trumpet bodies simultaneously from the communicating mouthpiece body through the connecting body, so that the sounds of all the trumpet bodies are produced, and a predetermined chord can be produced as a whole.

[0003] Patent Document 2 discloses a reed instrument in which a metal reed inside produces sound by manually expanding and contracting a piece of paper folded into an accordion shape. It also describes the generation of chords by providing multiple reeds on a base plate arranged on the side of the accordion portion, as shown in Figure 6 of the same document.

[0004] [Patent Document 1] Japanese Utility Model Application Publication No. 6-068091 [Patent Document 2] JP 2014-089429 A Summary of the Invention [Problem to be solved by the invention]

[0005] However, the wind instrument described in Patent Document 1 has a structure in which multiple trumpet bodies are fixed to a connecting body. Therefore, only one type of chord can be generated. Similarly, the reed instrument described in Patent Document 2 has a structure in which multiple reeds are fixed to a base plate, so that, like Patent Document 1, only one type of chord can be generated. Thus, the inventions described in Patent Documents 1 and 2 have a problem in that they are structurally unable to generate multiple different chords.

[0006] The present invention has been made in consideration of the above-mentioned points, and its main object is to provide a chord generating method that enables a performer or a third party to selectively and easily generate a plurality of different chords by selecting a plurality of single tone generating devices and preparing them as chord generating devices. [Means for solving the problem]

[0007] The chord generating method according to the present invention includes the steps of: arbitrarily selecting at least two single tone generating devices as chord generating devices from a set of a plurality of single tone generating devices that generate different single tones from each other; and manually adjusting the entire chord generating device. While holding together and a step of pressing or bending the individual single tone generating devices constituting the chord generating device together to simultaneously generate single tones, thereby generating a chord as a whole.

[0008] According to this method, first, at least two single tone generating devices are arbitrarily selected as chord generating devices by the performer or a third party from a set of a plurality of single tone generating devices that generate different single tones. The more single tone generating devices that can be selected from the set, the more types of chords that can be generated. Next, the performer manually assembles all of the single tone generating devices that make up the chord generating devices that have been previously selected and prepared. While holding togetherBy pressing or bending them all at once, different tones are generated simultaneously from each of the single tone generating devices that make up the chord generating device. As a result, a predetermined chord can be easily generated by such a simple operation. Next, by selecting at least two single tone generating devices in a different combination from the set of multiple single tone generating devices, a chord different from the previous one can be generated. Therefore, multiple different chords can be selectively and easily generated.

[0009] The single note generating device of the present invention is a single note generating device used in the above-mentioned chord generating method, and comprises a main body having a cylindrical portion and ends formed on both axial ends of the cylindrical portion, and a reed portion provided on at least one of the ends, and is configured to produce a single note from the reed portion by bending the main body.

[0010] According to this configuration, when the main body is bent by pushing or bending, the air inside the main body is compressed and pushed out through the reed portion, so that a single note is generated by a simple action. Therefore, a single note generating device suitable for simultaneously playing multiple single notes to generate chords is obtained.

[0011] The main body may be made of an EVA sponge material having a hardness of 30 degrees or more and 40 degrees or less, and the cylindrical portion may have a thickness of 3 mm or more and 7 mm or less. By defining the structure of the main body in this manner, even if the user is, for example, a small child or a person with impaired dexterity, they can easily bend the main body by grasping it, and can easily restore the main body to its original shape by releasing their grip.

[0012] That is, if the hardness is less than 20 degrees or the thickness of the cylindrical portion is less than 3 mm, the main body will be difficult to restore even if the user loosens his grip on it. On the other hand, if the hardness is greater than 40 degrees or the thickness of the cylindrical portion is greater than 7 mm, the main body will be difficult to bend sufficiently unless the user grips the main body with a relatively large grip. Therefore, as described above, it is desirable that the main body be made of EVA sponge material with a hardness of 30 degrees or more and 40 degrees or less, and that the thickness of the cylindrical portion be 3 mm or more and 7 mm or less.

[0013] The thickness of the end portion is greater than the thickness of the cylindrical portion. big It is preferred. This makes it possible to easily bend the tubular portion of the main body while reliably holding the lead portion at the end of the main body, thereby making it possible to adequately protect the lead portion by the end and suppress wear of the lead portion when the toy is in use.

[0014] The chord generating device of the present invention is a chord generating device used in the above-mentioned chord generating method, and the single note generating device comprises a main body having a cylindrical portion and end portions formed on both axial ends of the cylindrical portion, and a reed portion provided on at least one of the end portions, and is configured to produce a single note from the reed portion by bending the main body. With this configuration, it is possible to obtain a chord generating device suitable for the chord generating method described above, which can selectively and easily generate a plurality of different chords.

[0015] The set of single tone generating devices may be such that the single tones generated by the reed portion constitute a musical scale. With this configuration, the chord generating device can be made suitable for intellectual training, for example by selecting single notes from a series of scales and trying out combinations of notes. Effect of the Invention

[0016] According to the present invention, unlike the method in which a chord is generated as a whole by a plurality of performers each generating different single tones, a chord can be generated by a single performer, and moreover, the plurality of single tone generating devices that constitute the chord generating device can be operated by hand. While holding together Chords can be easily generated by simply pressing or bending the single notes together. In addition, since at least two of the multiple single note generating devices are selected at will, the chords that can be generated have a high degree of freedom.

[0017] Furthermore, since the combination of single tone generating devices can be selectively and easily designated in advance by a third party other than the performer, the performer can generate chords without any trouble when playing. In other words, even if the performer is a small child or an elderly person who has difficulty selecting and operating chords on an instrument when playing music, if an instructor prepares the chord generating devices before the performance and the performer operates the chord generating devices according to the instructor's instructions, music including chord generation can be easily performed. Of course, it becomes possible to play by generating chords by oneself. [Brief description of the drawings]

[0019] Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings. However, the present invention is not limited to the following embodiment.

[0020] Fig. 1 shows the appearance of a single tone generating device 1 in this embodiment, and Fig. 2 shows a cross-sectional structure of a main body 3 of the single tone generating device 1. Fig. 3 shows a chord tone generating device 10 in this embodiment. Fig. 4 shows the single tone generating device in a pushed state, and Fig. 5 shows the single tone generating device in a bent state. Fig. 6 shows the chord tone generating device in a pushed state. It should be noted that the chord generating tool 10 and the single tone generating tool 1 in this embodiment are not limited to the configurations shown in FIGS.

[0021] The chord generating method in this embodiment can be performed, for example, by using a chord generating tool 20 shown in Fig. 6. The chord generating tool 20 is composed of a plurality of single tone generating tools 1. 1 and 2, the single sound generating device 1 has a hollow main body 3 and a reed portion 5 provided on the main body 3. The main body 3 has a cylindrical portion 11 and end portions 13 formed on both ends of the cylindrical portion 11 in the axial direction A.

[0022] The tubular portion 11 in this embodiment is formed in a cylindrical shape. The shape of the tubular portion 11 is not limited to this, and may be a tubular shape of another shape, such as a tubular shape with an elliptical cross section or a tubular shape with a polygonal cross section. The end portion 13 is a portion formed so as to close both ends of the tubular portion 11. The end portion 13 is formed integrally with the tubular portion 11. The outer edge of the end portion 13 is formed in a tapered or rounded shape.

[0023] The diameter of the main body 3 is, for example, about 4 cm. The length of the main body 3 in the axial direction A is, for example, about 17 cm. The diameter and length of the main body 3 are not limited to these values ​​and may be changed appropriately according to the user.

[0024] A lead portion 5 is provided at one end 13 of the cylindrical portion 11. The lead portion 5 has a reed body 15 that produces a sound, and a cylindrical case 16 that houses the reed body 15. A through hole 17 is formed in the center of one end 13, and the case 16 that houses the reed body 15 fits into the through hole 17, whereby the lead portion 5 is attached and fixed to the end 13.

[0025] The reed portion 5 may be provided at each of both ends 13 of the tubular portion 11. However, by providing the reed portion 5 at only one end 13, it becomes possible to increase the flow rate of air passing through the reed portion 5, making it easier to produce a relatively loud sound.

[0026] The single sound generating device 1 is configured such that, by bending the main body 3, the air inside the main body 3 is pushed out through the reed body 15 to the outside, thereby generating a sound from the reed portion 5. The single tone generating device 1 is configured so that it can be easily bent with one or both hands. For example, as shown in Fig. 4, the single tone generating device 1 can be bent by gripping and pushing the central portion of the main body 3 with one hand. Also, as shown in Fig. 5, it is possible to bend the central portion of the main body 3 by gripping and bending both ends 13 of the single tone generating device 1.

[0027] The main body 3 of the single sound generating device 1 in this embodiment is made of an EVA sponge material with a hardness of 30 degrees or more and 40 degrees or less. For example, it is particularly preferable that the hardness of the main body 3 is about 35 degrees. The thickness of the cylindrical part 11 is 3 mm or more and 7 mm or less. For example, it is particularly preferable that the thickness of the cylindrical part 11 is about 5 mm.

[0028] The thickness of the end portion 13 is greater than the thickness of the cylindrical portion 11. Large The thickness of the end 13 is preferably 17 mm or more and 23 mm or less. For example, it is particularly preferable that the thickness of the end 13 is about 20 mm. Also, it is desirable that the thickness of the tubular portion 11 is about 1 / 4 of the thickness of the end 13. Note that the main body 3 is not limited to the EVA sponge material, and may be formed of other materials such as synthetic resin materials.

[0029] 3, the chord generating device 20 in this embodiment is made up of a plurality of single tone generating devices 1 arbitrarily selected from a set 10 including a plurality of the above-described single tone generating devices 1. In particular, the set 10 of single tone generating devices is a set of a plurality of single tone generating devices 1 such that the single tones generated by the reed portion 5 constitute a scale (for example, the scale of do-re-mi-fa-so-la-si-do), and the chord generating device 20 is configured to arbitrarily select at least two single tone generating devices 1 from the set 10 to generate chords.

[0030] As shown in Fig. 3, each single tone generating device 1 is engraved with a letter 7 representing one of the sounds (e.g., Do, Re, Mi, Fa, So, La, Si, or Do) that is to be produced by the single tone generating device 1. For sounds that differ by one octave (e.g., "Do"), a circle is engraved under the letter 7 representing the lower tone, and a circle is engraved above the letter 7 representing the higher tone. In this way, the single tone generating device 1 that produces the desired tone can be identified by sight and touch.

[0031] Next, a chord generating method will be described. Figures 7 to 9 show examples of chords generated by the chord generating tool 10. The chord generating method in this embodiment is a method of generating chords using the chord generating tool 20 described above.

[0032] First, as shown in Fig. 3, at least two single tone generating devices 1 are arbitrarily selected from a set of a plurality of single tone generating devices 1 that generate different single tones, and as shown in Fig. 6, the selected plurality of single tone generating devices 1 are made into a chord generating device 20. At this time, the selection of the single tone generating devices 1 that compose the chord generating device 20 may be performed not only by the performer (the user himself / herself) but also by a third party (for example, an assistant such as an instructor). In this way, even if the performer is, for example, a small child or an elderly person, he / she can enjoy playing by generating chords.

[0033] When three single tone generating devices 1 are selected, for example, the notes C, E, and G shown in Fig. 7 or the notes E, G, and B shown in Fig. 8 can be combined. When two single tone generating devices 1 are selected, for example, the notes C and G shown in Fig. 9 can be combined. Note that these chords are merely examples, and any chord can be generated.

[0034] Next, as shown in Fig. 6, the prepared chord generating devices 20 are grasped as a whole in the hand and pushed or bent together. Since each single tone generating device 1 has a cylindrical main body 3, it is easy to grasp the whole device as a whole in the hand by aligning the axial direction.

[0035] An example of a pushing operation is shown in Fig. 6. When pushing, the central portion of each single tone generating device 1 (i.e., the central portion of the chord generating device 20) is grasped and pushed in. On the other hand, when bending, it is possible to grasp both end portions of the chord generating device 20 (i.e., both end portions of a plurality of single tone generating devices 1) and bend the whole in the same manner as in the case of the single tone generating device 1 shown in Fig. 5.

[0036] When the main body 3 is pushed or bent, the air inside the main body 3 is compressed and pushed out through the reed portion 5. This causes each single tone generator 1 to simultaneously generate a single tone, and as a whole, a chord is generated. Any number of sounds can be selected and combined from the set of single sound generators 1, allowing users to enjoy free combinations of sounds.

[0037] Thus, according to the chord generating method of the present embodiment, a chord can be generated even by a single performer, which is quite different from a method in which a chord is generated as a whole by having multiple performers each generate different single tones, and a chord can be easily generated by a simple operation of pushing or bending the multiple single tone generating devices 1 constituting the chord generating device 20 together while holding them together in the hand. Moreover, since the method involves arbitrarily selecting at least two from the multiple single tone generating devices 1, a remarkable effect is achieved in that the chords to be generated have a high degree of freedom. In other words, unlike a method in which one type of chord is generated that is preset, a plurality of different chords can be selectively generated, and each chord can be easily generated by a simple operation.

[0038] Furthermore, according to the chord generating method of this embodiment, when playing music, the performer or a third party can selectively and easily specify the single tone generating devices 1 in advance, so that the performer can generate chords by using the selected multiple single tone generating devices 1 as chord generating devices 20 without any trouble during performance.

[0039] This allows even those who have difficulty selecting chords using an instrument during musical performance, such as young children or the elderly, to play music including chord generation by having an instructor prepare the chord generating device 20 before the performance and for the player to operate the chord generating device 20 according to the instructor's instructions. Of course, it is also possible to play by generating chords on one's own.

[0040] Furthermore, the single tone generating device 1 and the chord generating device 20 in this embodiment can be used not only to generate single tones or chords, but also, for example, for use by young children to play with their hands, or for people with disabilities in their manual movements to have fun while training their hand functions.

[0041] In this embodiment, as described above, the hardness of the EVA sponge material constituting the main body 3 is 30 degrees or more and 40 degrees or less, and the thickness of the cylindrical portion 11 is 3 mm or more and 7 mm or less, which is a specific configuration. Since the single - tone generator 1 has such a specific main - body configuration, even if the user is an infant or a person with a disability in the movement of the hands, by gripping the main body 3, the main body 3 can be easily bent, and moreover, by loosening the gripping force, the main body 3 can be easily restored to its original shape.

[0042] That is, when the hardness of the main body 3 is less than 20 degrees or the thickness of the cylindrical portion 11 is less than 3 mm, it is difficult to easily restore the main body 3 even if the user loosens the gripping force on the main body 3. On the other hand, when the hardness of the main body 3 is greater than 40 degrees or the thickness of the cylindrical portion 11 is greater than 7 mm, it is difficult to sufficiently bend the main body 3 unless the user grips the main body 3 with a relatively large gripping force. As a result, it becomes difficult to make a sound as the user wishes. Therefore, as described above, it is desirable that the main body 3 is composed of an EVA sponge material with a hardness of 30 degrees or more and 40 degrees or less, and the thickness of the cylindrical portion 11 is 3 mm or more and 7 mm or less.

[0043] Also, in the single - tone generator 1 and the harmony generator 20 in this embodiment, the thickness of the end portion 13 is Large greater than the thickness of the cylindrical portion 11. Therefore, by making the thickness of the cylindrical portion 11 relatively thin and the thickness of the end portion 13 relatively thick, the shape stability of the entire main body 3 is enhanced. Furthermore, while securely holding the lead portion 5 at the end portion 13 of the main body 3, it becomes possible to easily bend the main body 3 at the cylindrical portion 11. Therefore, the lead portion 5 can be appropriately protected by the end portion 13, and the wear of the lead portion 5 during the use of the single - tone generator 1 and the harmony generator 20 can be preferably suppressed.

[0044] Furthermore, in the set 10 of single tone generating devices in this embodiment, the tones of the reed parts 5 of the multiple single tone generating devices 1 together form a musical scale. Therefore, the chord generating device 20 can be made suitable for intellectual development, for example, by selecting any single tone from a series of scales and trying out combinations of tones.

[0045] In addition, multiple users can each have the single sound generating device 1, and each person can freely play different sounds or play in rhythm with music. It can also be used for playing various games.

[0046] Incidentally, the above-mentioned single sound generating device 1 has been described as having the cylindrical portion 11 and the reed portion 5 provided at the end portion 13, but the configuration of the single sound generating device is not limited to this. For example, the single sound generating device may have a bellows body (not shown) and side plates (not shown) provided at both ends thereof, with lead portions (not shown) provided on the side plates. Alternatively, the single sound generating device may have a bendable main body (not shown), a sensor portion (not shown) that detects the bent state of the main body, and a single sound generating portion (not shown) that generates an electronic sound in response to the output of the sensor portion.

[0047] Even if the single tone generating device is configured in this manner, the same effects can be obtained as with the single tone generating device 1 having the above-mentioned cylindrical main body 3 and reed portion, and the chord generating device 10 equipped with the same, and the above-mentioned chord generating method can be realized. [Industrial Applicability]

[0048] INDUSTRIAL APPLICABILITY As described above, the present invention is useful for a chord generating method for selectively generating chords, and for a single note generating device and a chord generating device used therein. [Explanation of symbols]
