Description

Concentric tube daegeum that forms a similar tone and shape as Korean general daegeum}

The present invention relates to a double pipe daegeum that has a similar tone and shape.

Daegeum was first mentioned in the Samguk Sagi (History of the Three Kingdoms), along with Junggeum and Salt, as the Silla samjuk (三竹). The material used was yellow bamboo (黃竹) that had been aged for several years, but now Ssangol bamboo (雙骨竹) is often used. The vocal range extends to about two and a half octaves, and the tone is wide and soft in Ja-chwi (low-pitched sound), and clear and yuk-chwi (力吹) in Pyeong-chwi (low-pitched sound). , blowing hard), it has a firm and cheerful sound, and its variations are diverse, so it is often used as a solo instrument.

There are two types of daegeum: the Jeongak daegeum and the Sanjo daegeum (Sinawi daegeum), which produces a sound about 2 major degrees higher. The length of the Jeongak daegeum is about 80 cm, and the Sanjo daegeum is about 70 cm.

As shown in Figure 1, the daegeum is closed at one end and has an opening (8) through which air is blown into the closed end. There are a total of six holes (Jigong 1 to Jigong 6), which are holes for controlling the scale by touching with the finger, and at the opposite end of the mouthpiece (8), there is a Chilseonggong (7), which is not touched with the hand to control the note. According to Akhak Gwebeom, the rule is to form five chilseonggong (7), but these days, only one or two are formed.

Between the mouthpiece (8) and the hole (1 to 6), there is another hole called the hole (9). To this Cheonggong (9), a thin membrane called 'Cheong' collected from reeds is tightly attached. When a high note is blown, this Cheong vibrates and produces a unique and exciting sound. Cheong is very thin and can tear easily, and if the Cheong is played excessively, it will stretch or wear out and the sound will not be good, so a metal cover is placed over the Cheong hole of the daegeum. The size and tone of the cleaning stream vary depending on how much of the blue hole is covered with the blue screen. Generally, the more the blue screen is opened, the louder the cleaning air becomes.

To play, place the end of the mouthpiece on your left shoulder and then hold the instrument parallel to the ground. Turn your head to the left, bend slightly, place your lips on the mouthpiece, raise both arms horizontally with the ground, and as shown in an enlarged view of Figure 2 based on Figure 1, make 1 (1) finger each with your left index finger, middle finger, and ring finger, respectively. , point to hole 2 (2), hole 3 (3), and point to hole 4 (4), hole 5 (5), and hole 6 (6) with the index/middle/unknown finger of the right hand, respectively. If you actually try it, it's a very difficult posture because your head hurts, you have to stretch your arms a lot, and your fingers have to spread a lot because the holes are far apart. If you try it yourself, it can sometimes put a strain on your joints because you have to turn your head 90 degrees to the left and bend your wrists 90 degrees. Beginners may experience inflammation in their neck muscles or tenosynovitis in their wrists, and especially those with small or inflexible hands have a hard time learning for the first time.

Western instruments have been transformed to become the best instruments through much trial and error and have been passed down to today. However, compared to traditional Korean instruments, there has been a lack of systematic improvement over past instruments, so they are still following the structure of the past. Improvements to some daegeums have been attempted, such as an improved daegeum called gayo daegeum by changing the hole location or attaching a key, and a hapjuk daegeum made by combining split bamboo pieces. However, a daegeum using a double pipe body has never been attempted. .

The present invention seeks to solve this problem, and the purpose of the present invention is to embed an elastic body in the sound box space between the double pipes to function as a sound filter and to place a through hole in each hole like a daegeum to produce a daegeum sound, so that the weight is similar to that of a daegeum. The purpose is to provide a double-tube daegeum that is easy to use because it is light or light, and has a daegeum-like tone and shape that allows a daegeum-like tone to be realized by replacing the elastic material, which is an acoustic filter, in the sound chamber space when necessary.

Another object of the present invention is to reduce the weight by using the daegeum pipe as a double pipe body, insert an elastic body into the sound box space between the double pipe bodies to function as a sound filter, and place a through hole at the same hole location as the daegeum to produce a sound similar to the daegeum. The purpose is to provide a double pipe daegeum that has a similar tone and shape to a daegeum that can be produced inexpensively without purchasing expensive materials such as Ssanggol porridge because it uses a double pipe body, and also improves durability.

Hereinafter, Embodiment 1 of the present invention will be described in detail with reference to the drawings.

A partition wall 40 connecting the coaxial inner tube 20 and the outer tube 30 and the inner tube 20 and the outer tube 30 to provide at least one sound box space between the inner tube 20 and the outer tube 30. A double tube body (50) having a;

An elastic band (60) inserted into the sound box space and functioning as a sound filter;

It vertically penetrates the exterior 30, the elastic band 60, and the inner tube 20, and forms holes 1 to 6 ( 11~16), Chilseonggong (17), Chugu (18), and Cheonggong (19);

A stopper (80) blocking the end of the mouthpiece (18) side of the double pipe body (50); and

It blocks the end of the double pipe body (50) on the side of the chilseong hole (17), and includes a ring cap (81) having an inner hole (82) communicating with the inner pipe (20), and an acoustic filter is installed in the sound box space between the inner and outer pipes of the double pipe metal pipe. It is composed of built-in features.

The through hole is formed in the exterior 30, the elastic band 60, and the inner pipe 20, and the exterior holes 31a to 31i corresponding to the hole 1 to hole 6, the chilseong hole, the mounting hole, and the hole position of the daegeum. It is configured to include a double tube hole consisting of (21a to 21i), elastic body holes (61a to 61i) located between the double tube holes, and ring bodies (70a to 70i) inserted so that the holes are connected vertically. In the drawings (FIGS. 3 to 7) of the present invention, the illustration of blue and blue blinds is omitted.

In the present invention, hole 1 to hole 6 (11 to 16), chilseong hole (17), mouthpiece (18), and hollow hole (19) shown in Figure 4 are designated as through holes, and in Figure 3, they are the double pipe of the double pipe body (50). Hole is used as a term to define the outer hole (31) and inner hole (21) shown in Figures 6 and 7 with one notation, and is divided into outer hole (31a~31i) and inner hole (21a~21i) by location. They are marked separately.

In addition, the elastic body holes (61) are marked as elastic body holes (61a~61i) by position, and the ring body (70) is also marked by dividing them into ring bodies (70a~70i) by position of the elastic body holes (61a~61i).

The partition wall 40 may be composed of two or more pieces, and includes an elastic band 60 that fills the sound box space and has elastic holes 61a to 61i in the through hole portion,

It further includes an auxiliary elastic band (60') filled in the sound box space in the area where there is no through hole.

The portion without the through hole may be one in which at least two sound box spaces are formed as partition walls and filled with at least one auxiliary elastic band 60'.

For example, the partition wall 40 may be formed in a Y shape to represent a double-bone bamboo shape between the outer wall 30 and the inner wall 20, and a groove may be formed in the outer wall 30.

The technical principle of the present invention is in the sound box space formed on the inner tube 20 and the outer tube 30 by the partition wall 40 supporting the inner tube 20 and the outer tube 30 of the double tube body 50 in FIG. An elastic band 60 is inserted into a hole and has an elastic hole 61 penetrating the double tube hole (consisting of an outer hole 31 and an inner hole 21), and the elastic hole 61 of the elastic band 60 is inserted. ), a ring body 70 is further inserted into the inner diameter of the elastic body hole 61 and fixed so that the upper and lower ends are located between the outer hole 31 and the inner hole 21.

The double pipe body 50 in the present invention is preferably made of aluminum or engineering plastic, which is light and has good extrusion force, but is not limited to this and can be replaced with a light and strong material. The stopper 80 and the ring cap 81 in the present invention are preferably made of brass, which is an example because it is resistant to corrosion and has a soft strength to withstand the expansion and contraction of the double pipe body 50 to the external air, and has these properties. Can also be used with other materials. The elastic band 60 and the auxiliary elastic band 60 in the present invention may be made of an elastic material such as Ethylene-vinyl-acetate foam (EVA foam), Nitrile-butadiene rubber (NBR), or sponge foam. and is not limited to this. In the present invention, it is recommended to use porous foam to reduce weight.

The ring body 70 in the present invention is preferably made of epoxy resin, because it provides water resistance and airtightness with the elastic body hole 61 between the outer hole 31 and the inner hole 21.

The present invention provides a sound similar to that of a daegeum, but has a similar weight but is lighter, so that users can easily use it and provide durability. In order to be able to select and use the desired tone, the auxiliary elastic band (60') is filled in the sound box space or part of the sound box is removed. It provides an effect that can implement a filter function (changes the tone), which can be confirmed by Table 1 and Table 2.

The playing method of the present invention is the same as that of the general daegeum, so it is omitted, and the elastic band 60 and the auxiliary elastic band 60' are formed of Eva foam, and the ring body 70 is formed of epoxy resin in the cross-sectional shape as shown in Figure 7. Using this, Jeochwihwang and Pyeongchwihwang, which are jeongak daegeum intervals, were measured and shown in Tables 1 and 2.

Table 1 shows that it is possible to implement various changes in timbre for the Jeongak Daegeum pitch of Jeochwihwang and Table 2 shows Pyeongchihwang. FFT-envelope technique was used to analyze timbre.

In the present invention, it is possible to express various changes in timbre with respect to the pitch of Jeongak Daegeum of Low and Pyeongchwihwang. In the case of the instrument using the double tube body (50), the main material is metal or a metal substitute material and is relatively thin, so the low tone is suppressed throughout the audible frequency and the unique sound is produced. A sharp high-pitched sound is generated, but the sound of the mid-low range is abundantly reinforced by the sound chamber formed inside the double tube, and the sharp high-pitched sound is appropriately filtered depending on the amount of elastic band applied, making it possible to achieve the desired daegeum sound. In other words, the wind supplied through the mouthpiece 18 blocks or opens the holes 11 to 16 to generate a sound of the corresponding pitch, and the generated sound passes through the inner hole 21 and the ring body 70 to the opening hole. High-pitched sounds are absorbed (filtered) by the elastic band 60 around the elastic hole 70, and the sound filtered in this way is output as a pseudo-daegeum sound through the outer hole 31. In addition, the auxiliary elastic band 60' serves as another sound chamber space that emits sound while discharging through the inner tube 20 to the inner hole 82 of the ring cap 81, and reinforces mid-low sounds while auxiliary absorbing/suppressing and filtering high-pitched sounds. A variety of tones can be provided, and users can provide unique daegeum tones by removing or filling in some parts. This is a similar principle to how various tones are harmonized through a choir and each choir has different tones.

Another embodiment 2 of the present invention, as shown in Figure 8, includes a coaxial inner tube 20 and an outer tube 30, and a double tube body 50 providing a sound box space between the inner tube 20 and the outer tube 30;
