Description

  The present invention relates to ocarina and a method for producing the same. In particular, the present invention relates to an ocarina that performs tuning using a member for a finger hole portion that is inserted into the ocarina body, and a method for manufacturing the ocarina.

Ocarina is a musical instrument that is pronounced by breathing in through the air vents provided on the body, and can change the sound produced by differences in the way of closing multiple finger holes (usually 12). It is a musical instrument. Ocarina is a musical instrument that has been used for a long time, and in particular, ceramic ocarina has been conventionally produced (prior art documents 1 and 2).
It is known that ocarina can be tuned by performing an operation to sharpen and widen the finger holes. Therefore, in the past, in order to produce a ceramic ocarina that provides an appropriate pitch, the following steps have been taken. A process of forming a shell-like body having a hollow inside by overlapping the clay of the upper half body and the lower half body having finger holes, and drying the shell-like body. A process of tuning the finger holes with a cutting tool on the dried shell. Further, after the shell-like body is fired at a temperature of about 800 ° C., the finger holes are shaved again with a cutting tool and reconditioned (FIG. 5). In this way, tuning was performed twice. Because the ceramic ocarina shrinks as a whole after drying and firing, even if it is tuned at the initial stage of production, there is a possibility that the pitch may shift after firing, and firing. It is because it becomes hard after going through this process, and it is necessary to cope with the problem that cutting is difficult.

Japanese Patent Laid-Open No. 6-12058 Special table 2008-505838

However, the work of cutting the finger holes is performed while confirming the sound, which is time consuming and requires a high level of skill from the shaving processor. This is because it is difficult to reduce a hole that has been enlarged once, and the processing work cannot be performed unless the user knows where and how to cut to obtain an appropriate pitch. Also, it is difficult for producers with advanced skills to completely prevent over-drilling, so about a few percent of defective products were generated as a whole, but the defective products could only be discarded. .
In addition, the ceramic ocarina made by scraping the finger holes is coated with an oil-based paint to protect the ocarina surface. However, organic substances contained in the paint may cause an allergic reaction. there were. It may be possible to cope with this problem by not painting, but the fact that cutting work is possible means that it is so brittle, and shipping ocarina without painting has a problem in terms of quality. It was.
In addition, considering only increasing the hardness, it is possible to make it magnetic, or to increase the firing temperature to 1000 degrees or more, but because the hardness is high, it is difficult to scrape the finger holes and appropriately It was extremely difficult to produce tuned porcelain ocarina.

It is a conceptual diagram which inserts a finger hole formation member in the body of ocarina. It is a manufacturing-process figure of this embodiment using a finger hole formation member. It is a conventional manufacturing process diagram.

  Below, the form for implementing this invention is demonstrated.

First, the structure of the ocarina body 1 and the finger hole forming member 2 will be described.
A mounting hole 3 into which the finger hole forming member 2 can be inserted is formed in the ocarina body 1. This mounting hole 3 is formed in a hole shape that is slightly larger than a hole that is normally drilled as a finger hole. The mounting hole 3 is formed at a position corresponding to the position where the finger hole forming member 2 shown in FIG.
A typical finger hole forming member 2 is shown in FIG. As shown in FIG. 2 (A), the finger hole forming member 2 is made of rubber, and has a configuration in which the body 4 is cylindrical and the flanges 5 are integrally formed at both ends thereof. . The finger hole forming member 2 is inserted into the mounting hole 3 of the ocarina body 1 and mounted on the body 1 as shown in FIG. This mounting is performed with the finger hole forming member 2 in close contact with the body 1.
Since the flange 5 provided at one end of the trunk 4 covers the gap between the mounting hole 3 drilled in the body 1 of the ocarina and the trunk 4 of the finger hole forming member 2, the air blown from the blowing port is the gap Will not flow out of Ocarina. Further, the finger hole forming member 2 is prevented from easily falling off by the collar portion 5 provided at the other end of the trunk portion 4.

The finger hole forming member 2 of Modification 5 shown in FIG. 2 (F) has a structure in which a plurality of through holes serving as finger holes are provided in one finger hole forming member 2. In other words, two finger hole forming members 2 are integrally formed to constitute one finger hole forming member 2. By adopting such a configuration, it is possible to arrange the finger holes adjacent to each other. This is advantageous for the user because it is possible to manufacture ocarina with increased playing techniques and fingering freedom.
The finger hole forming member 2 of Modification 6 shown in FIG. 2G is an example in which the finger hole forming member 2 is configured by integrating a plurality of members. This modification 6 is composed of an outer cylindrical body 7 and an inner cylindrical body 8 as shown well in FIG. 3C, and an inner cylindrical shape is formed on the cylindrical portion 9 of the outer cylindrical body 8. The body 8 is configured to fit. And the nail | claw part 10 is formed in the lower end part seeing in the figure of the outer side cylindrical body 7 toward radial inner direction, and this claw part 10 is outside radial direction by fitting of the said inner side cylindrical body 8. The finger hole forming member 2 is fixed to the body 1 by protruding outward. Note that the outer cylindrical body 8 and the inner cylindrical body 8 are each formed with flanges 5 and 5 that perform the same functions as in the above-described examples at the upper end. And the through-hole 11 formed in the inner side cylindrical body 8 is a finger hole.

In this case, the outer cylindrical body 7 is first inserted into the mounting hole 3 of the body 1, and the inner cylindrical body 8 is inserted into the cylindrical portion 9 of the outer cylindrical body 7. Then, the nail | claw part 10 of the lower end part of the outer side cylindrical body 7 deform | transforms to radial direction outward, and is fixed and attached to the body 1. FIG. In addition, the mounting state among the mounting hole 3, the outer cylindrical body 7, and the inner cylindrical body 8 is all in a close contact state.

Next, based on FIG. 4, each process of manufacturing an ocarina and manufacturing an ocarina by attaching a finger hole forming member to an attachment hole formed in the body will be described.
First, the body of ocarina is formed in a predetermined shell shape in which the upper half and the lower half are bonded together to form a hollow inside. The upper half and the lower half are each manufactured by putting ceramic clay into a mold, then pressing and solidifying the mold ("S101" step).
Next, after forming the upper half and lower half mounting holes 3 and the singing singing (step "S102"), the upper half and the lower half are bonded together (step "S103"). When sticking together, apply a lip to the part where the upper half and the lower half meet. The gutter plays the role of an adhesive, and is a well-known thing used when performing ceramics and the like.
After the upper half and the lower half are bonded together as described above, natural drying is performed at room temperature (“S104” step). The body hardened to some extent by natural drying is fired (“S105” step), and then a glaze is applied (“S106” step).
The body to which the glaze is applied is further baked a second time (“S107” step). By this firing, a vitreous layer is formed on the outer surface of the body. After firing as described above, the vitreous layer is polished to complete the production of the body (“S108” step).
Thereafter, as shown in each drawing of FIG. 3, the finger hole forming member 2 is inserted into the mounting hole 3 provided in the body 1, and it is confirmed whether or not the selection of the finger hole forming member 2 is appropriate. A test blow is performed for the confirmation, but if there is no appropriate sound, the finger hole forming member 2 is replaced and the test blow is performed again. The operation is repeated until it is determined that an appropriate pitch is produced (“S109” step). When the finger hole forming members 2 are appropriately selected for all the mounting holes 3, the tuning operation is completed, and all the manufacturing steps are completed.

According to the ocarina and the manufacturing method thereof according to the above-described embodiment, it is unnecessary to adjust the pitch by cutting the ocarina body 1, and it is possible to produce the ocarina without requiring a high degree of skill.
In addition, since it is possible to adjust the pitch by exchanging the finger hole forming member 2, if a mounting hole for inserting the finger hole forming member 2 is manufactured, fine adjustment is performed after the body 1 is dried. It is possible to adjust to an appropriate pitch by appropriately selecting the finger hole forming member 2 after firing. Thereby, the production process can be shortened and the production efficiency can be increased.
Moreover, since the operation | work which cuts a finger hole in the body 1 itself and adjusts does not generate | occur | produce, even if it is a magnetic ocarina, it becomes possible to adjust to an appropriate pitch. In addition, since replacement can be performed many times, even a person who does not have a high level of skill can perform tuning work, and the occurrence rate of defective products can be reduced.
Furthermore, as a body manufacturing process, when a glaze is applied to the outer surface of a predetermined shell shape and then fired to form a vitreous layer on the outer surface of the body, the outer surface of the body is less likely to be damaged. . As a result, it is no longer necessary to apply an oil-based paint, and the problem of allergic reaction is eliminated.

As mentioned above, although the embodiment of the present invention has been described using one example, the present invention can be implemented in various forms in addition to the above example.
For example, as shown in FIG. 3A, there is no need to create a gap between the mounting hole of the ocarina body and the body portion of the finger hole forming member, and it may be mounted in close contact. As long as the part is brought into close contact with the finger hole forming member, it is also possible to adopt a structure in which the collar part is not provided.
The finger hole forming member does not have to be made of rubber, and can be made of various materials such as resin and metal other than rubber. However, depending on the material, there may be a gap in which air leaks between the ocarina body and the finger hole forming member. In such a case, it is necessary to provide a seal structure for closing the gap. In the present invention, the closely attached mounting state means a mounting state in which a gap that causes air leakage is not formed when the finger hole forming member is mounted in the mounting hole of the body. As described above, a structure in which another member such as a seal member is interposed between the mounting hole and the finger hole forming member is also in contact with the mounting hole and the finger hole forming member.
In addition, when the finger hole forming member is made of a material other than rubber, at least a part of the finger hole forming member may have an elastic structure, and the finger hole forming member may be locked to the ocarina body using the elastic structure. Is possible.
In addition, the circumference of the mounting hole drilled in the ocarina body is made one step lower than the circumference, and the heel part of the finger hole forming member is arranged in the part so that the heel part does not protrude from the ocarina body. It is also possible to do.
Moreover, it is also possible to prevent the finger hole forming member from entering the inside of the ocarina by giving the collar part a certain degree of rigidity.
Further, the finger hole forming member can be configured as a separate body from the part for locking in the mounting hole of the body and the main body part for forming the finger hole. Even in such a case, both parts need to be in a close contact state as referred to in the present invention.
In addition, the finger holes of the through holes formed in the finger hole forming member may be formed in advance before the finger hole forming member is attached to the attachment hole of the body, or may be formed after the attachment. good. In this case, even if the drilling of the through hole of the finger hole fails, it is only necessary to replace the finger hole forming member, and the body does not have to be discarded.
