Manufacturing method of 14-hole ocarina {MANUFACTURING METHOD FOR OCARINA HAVING FOURTEEN HOLE}

The present invention relates to a method for manufacturing a 14-hole ocarina, and more specifically, using powdered clay as a material, and improving the size, thickness and shape of the sounding space, pitch hole, sound hole, and mouthpiece so as to produce a clear sound. It relates to a method for producing a 14-hole ocarina.

In general, Ocarina instruments are favored by many people because of their elegant tone, with the upper edges sticking out and blowing into the mouth, the top of which has pitch holes and the bottom of the pitch holes and sound holes. Although it is a diatonic scale, it can also produce chromatic scales by fingering.

Since the ocarina instruments are not closed as usual wind instruments, but closed everywhere, the ringing sound does not escape to the outside and the sound is reflected from the inside so that the sound resonates. That is, the wind blown by the mouth touches the edge (cracking) and makes a sound.

By the way, in Italy, known as the home of ocarina instruments, 11-hole ocarina instruments are used, and only the fingerings of "do, re, mi, wave, sole, la, poem, do, re, beauty, wave" are available. Individual solo is impossible, and therefore it is common to perform ensemble using Ocarina musical instruments having different keys.

In order to alleviate the inconvenience in using the ocarina instruments for the above reasons, a thirteen-hole ocarina instrument has been proposed in recent years that enables a low "la, poetry" fingering to be used alone.

Hereinafter will be described in detail the manufacturing process of the 14-hole ocarina according to the present invention made as described above.

First, in order to manufacture the ocarina musical instrument according to the present invention, four frameworks such as an upper outer mold, an upper inner mold, a lower outer mold, and a lower inner mold as shown in FIGS. 10 and 11 are required. At this time, each of the outer frame and the inner frame is coupled to each other, in this case, the concave portion is formed in each of the outer frame to be in contact with each other to fix the position, each inner frame is seated in the concave portion Convex portions are formed to be joined.

After having each mold as described above, to make a dough by mixing the clay and water in a ratio of 5: 2.5, and to produce a lower portion and an upper portion separately.

First, the process of making the lower part is described, pressing the dough into the corresponding part to make the shape of the mouthpiece in the lower outer mold. At this time, there is no gap and the manufacturer is pressed firmly using the finger for firmness.

After the above process, the position of the mouthpiece 15 'is determined by using the mouthpiece-shaped bar. Thereafter, while the work is being performed to prevent the shape change of the mouthpiece 15 ', the mouthpiece of the mouthpiece is continuously inserted.

The lower shape of the mouthpiece is made, and when the position of the mouthpiece is determined, a separate tool is scraped around the mouthpiece 15 'to form a comb pattern to roughen and soil water. The reason for this is to increase the adhesive force with the dough supplied to the lower outer mold later.

After the above process is made, put the dough lump in the lower outer mold and press firmly so that there is no gap. At this time, the surplus portion overflowing from the lower face mold is removed by using a thread or a separate means, and the edge portion is arranged. After that, it is dug up by mobilizing a separate extension in consideration of the lower eye shape is properly dug by the manufacturer.

Thereafter, the hollowed out space is trimmed and the lower inner frame is coupled to the lower outer frame to press down firmly to form a lower inner shape. At this time, the position is fixed according to the combination of the concave portion and the convex portion formed in the lower outer frame and the lower inner frame.

Subsequently, when the lower outer frame and the lower inner frame are separated, the 10th and 11th pitch holes and the sound hole 13 'are drilled, but if not completely drilled, the manufacturer makes the drill. At this time, the surplus portion overflowing from the lower face mold is removed again using a thread or a separate means.

After the above process is completed, the lower outer frame and the lower inner frame are combined to complete the shape of the lower part. After that, the edge 16 'is trimmed using a separate tool, and the sound hole 13' is completely drilled. After such a process is made, the plugged-out stick-shaped bar is pulled out to form the bedding 15 '.

Subsequently, the lower part of the ocarina musical instrument according to the present invention is completed by separating the lower outer mold.

On the other hand, when explaining the process of making the upper portion, put the dough lump in the upper outer mold and press firmly so that there is no gap, the excess portion overflowing from the upper outer mold is removed by using a thread or a separate means. Afterwards, it is dug up by using a separate extension, which is properly excavated by the manufacturer considering the upper eye shape.

Thereafter, the hollowed out space is trimmed, and the upper eye mold is combined with the upper outer mold to press firmly to form the upper eye shape. At this time, the position is fixed according to the combination of the concave portion and the convex portion formed in the upper outer frame and the upper inner frame.

Subsequently, if the upper outer frame and the upper inner frame are separated, the pitch holes of 1,2,3,4,5,6,7,8,9,12, and 14 are drilled, but not completely. It will be drilled by the manufacturer. At this time, the surplus portion overflowing from the upper face mold is removed again using a thread or a separate means.

Subsequently, the upper portion of the ocarina musical instrument according to the present invention is completed by separating the upper outer mold.

After the above process is made, once again, the sound hole 13 'and the mouthpiece 15' are correctly drilled, and soil water is polished and applied around the sound hole 13 '. At this time, the reason for applying soil water is to prevent the drying and to improve the convenience of the smoothing operation. While such an operation is being performed, the state in which the mouthpiece plug is inserted into the mouthpiece 15 'is continuously maintained. This is to prevent foreign matter from entering the mouthpiece 15 '.

Thereafter, the inner and edge portions 16 'of the sound hole 13' are finely trimmed using a pin or the like, and the sound hole 13 'and the sound hole 15' are removed by removing the mouthpiece bar from the mouthpiece 15 '. Trim the joints.

After the above process is made, each pitch hole is drilled correctly. At this time, each of the pitch hole is formed in the hole adjacent to the outer portion as shown in Fig. 9 is small and wider in the hemispherical shape toward the inner ringing space (17 ') to increase the flow rate and pressure to make the sound clear Be sure to At this time, since the pitch is changed according to the formed thickness, the thickness is adjusted to have a desired tone.

When the lower part and the upper part are completed by the above process, the exposed surface is scratched to roughen the surface, and the soil is applied to each other and then attached to each other. At this time, the adhesive edge is rubbed using a finger to increase the adhesive strength.

After completing as described above, by making a hook as needed and attaching it to a predetermined position, it is possible to carry around the neck using an obi or a musical instrument afterwards.

On the other hand, after the product is subjected to the above process for two days or three days after drying for a predetermined time tuning, the part to be cut and the part to be cut and polished by sandpaper or the like to trim the appearance. After that, dry it again for a predetermined time, and then roast it first, and then check the tuning again to make sure that all sounds are correct and clean up the appearance.

The present invention is not limited to the embodiments described above, and various modifications and changes can be made by those skilled in the art, which are included in the spirit and scope of the present invention as defined in the appended claims.

As described above, by applying the manufacturing method of the 14-hole ocarina of the present invention, it is possible to play a variety of music by having a 14 "hole" so as to enable a low "sol" fingering, changing the inclined cross-sectional shape of the mouth hole And the thickness of the edge opposite to the thinner and by changing the structure of the sound hole portion to prevent the sound is reflected back, the sound becomes clear.

In addition, the mouthpiece is formed thick so as to contact the sound hole, and the body wall is thickened to reduce the volume of the ringing space to reduce the pitch of the sound and at the same time save the player's breathing volume.
