Description

Technical Field

[0001] The utility model belongs to the technical field of national musical instruments, and relates to a dongxiao (a vertical bamboo flute) with two tones combined into one. Background Art

[0002] The dongxiao is one of the oldest and most common wind instruments blown by mouth of the Han nationality in China, and its timbre is soft and elegant.

[0003] Traditional materials for making dongxiao are black bamboo, white bamboo, cinnamon bamboo, mottled bamboo, etc. Among them, black bamboo is the most commonly used material and is also recognized as the most ideal material. Due to the fiber structure of bamboo and the hollow structure inside, the bamboo flute can produce a rich, pure and melodious unique timbre.

[0004] However, during the use of the bamboo flute, it needs to be handled with care and carefully maintained to avoid being dropped and damaged, and to prevent deformation and cracking when the humidity and temperature difference change greatly. Playing high notes suddenly on a bamboo flute that has not been played for a long time may also cause the bamboo flute to crack, seriously affecting the timbre and sound quality of the dongxiao, and even causing the dongxiao to be scrapped. Moreover, one bamboo flute corresponds to one key. If it is necessary to play different keys outdoors with a dongxiao, it is necessary to carry multiple dongxiao of different keys, which is very inconvenient to use and difficult to meet the actual needs.

[0005] With the progress of science and the development of society, some new materials are also used to make dongxiao, such as various metals, light alloys, resins, etc. Compared with the pure and soothing timbre of the bamboo flute, the timbre of the metal flute is bright, sharp and penetrating. Metals and alloys used to make flutes, such as titanium alloy, have a high specific strength, that is, high strength, light weight and good corrosion resistance. Therefore, the titanium alloy flute has good durability, the sound is more uniform and stable, the timbre retention is good, rich in layers, the timbre change is more abundant, and the volume is large. Although this kind of dongxiao can well solve the problems of deformation and cracking of traditional bamboo flutes, like the bamboo flute, it still corresponds to one key for one flute, which is very inconvenient to use and difficult to meet the actual needs. Content of the Utility Model

[0006] The purpose of the utility model is to provide a dongxiao with two tones combined into one, which not only realizes the combination of two tones into one, but also the two tones can be freely switched, is very convenient to use, and can meet the actual needs.

[0007] The technical scheme adopted by the utility model is as follows: the dongxiao is composed of a blowing tube, a sound hole tube, a fundamental tone hole tube and a key conversion connecting tube, wherein:

[0008] One end of the blowing tube is provided with a U-shaped blowing port, and the other end is connected with one end of the key conversion connecting tube;

[0009] The sound hole tube is divided into upper and lower parts with the horizontal cross-section of the tube axis as the dividing surface, and a plurality of sound holes of different keys are independently opened in the upper and lower parts;

[0010] On the inner sides of both ends of the fundamental tone hole tube, fundamental tone holes and consonant tone holes of different modes are respectively opened on the tube body.

[0011] In the middle upper part of the mode conversion connecting tube, the upper part is an open end communicating with the inner cavity of the tube, and the lower part is a sealed end.

[0012] The tone hole tube is sleeved outside the mode conversion connecting tube and can rotate. When multiple tone holes of one mode on it communicate with the inner cavity of the tube through the open end of the mode conversion connecting tube, multiple tone holes of another mode are sealed by the sealed end.

[0013] Both ends of the fundamental tone hole tube are adjustably connected to the other end of the mode conversion connecting tube. The fundamental tone holes and consonant tone holes on the fundamental tone hole tube on the same side as the connection end, and multiple tone holes communicating with the inner cavity of the mode conversion connecting tube are of one mode.

[0014] With the above structure, during use, since the blowing tube, the mode conversion connecting tube and the fundamental tone hole tube are connected in sequence and the inner cavities communicate with each other, a complete dongxiao is formed. By rotating the tone hole tube to make the tone holes of different modes communicate with the inner cavity of the mode conversion connecting tube, and selecting different ends of the fundamental tone hole tube to be connected to the other end of the mode conversion connecting tube, the tone holes, fundamental tone holes and consonant tone holes of one mode can be selected, so that the dongxiao has one mode. Repeating the above process can make the dongxiao have another mode, thus realizing the free conversion of double modes. It is very convenient to use, can meet the actual needs, and thus realizes the combination of double modes. Brief Description of the Drawings

[0021] As shown in the figure, the utility model is composed of a blowing tube Ⅰ, a sound hole tube Ⅱ, a fundamental sound hole tube Ⅲ and a mode conversion connecting tube Ⅳ, where:

[0022] As Figure 1 , Figure 5 shown, one end of the blowing tube Ⅰ is provided with a U-shaped blowing port 1, and the other end is provided with a concave interface 2, and is connected to the convex interface 8 at one end of the mode conversion connecting tube Ⅳ through the concave interface 2;

[0023] As Figure 2 shown, the sound hole tube Ⅱ is divided into upper and lower parts with the horizontal cross-section of the tube axis as the dividing surface, and a plurality of sound holes 3 and sound holes 4 of different modes are independently opened in the upper and lower parts respectively.

[0024] As Figure 3 shown, both ends of the fundamental sound hole tube Ⅲ are provided with concave interfaces 5, and fundamental sound holes and auxiliary sound holes of different modes are respectively opened on the tube bodies near the inner sides of the concave interfaces 5 at both ends of the fundamental sound hole tube Ⅲ, namely fundamental sound hole 6 and auxiliary sound hole 7, and fundamental sound hole 11 and auxiliary sound hole 12.

[0025] As Figure 4 shown, both ends of the mode conversion connecting tube Ⅳ are provided with convex interfaces 8, the upper part of the middle is an open end 9 communicating with the inner cavity of the tube, and the lower part is a sealed end 10.

[0026] As Figure 5 shown, the sound hole tube Ⅱ is sleeved outside the mode conversion connecting tube Ⅳ and can rotate. When a plurality of sound holes of one mode on it communicate with the inner cavity of the tube through the open end 9 of the mode conversion connecting tube, a plurality of sound holes of another mode are sealed by the sealed end 10.

[0027] The concave interfaces 5 at both ends of the fundamental sound hole tube Ⅱ are adjustably connected to the convex interfaces 8 at the other end of the mode conversion connecting tube Ⅳ. The fundamental sound holes and auxiliary sound holes on the fundamental sound hole tube Ⅱ adjacent to the concave interfaces 5 connected to the convex interfaces 8 at the other end of the mode conversion connecting tube Ⅳ, and a plurality of sound holes communicating with the inner cavity of the mode conversion connecting tube Ⅳ are of one mode.

[0028] The specific process of changing the mode of the utility model is as follows: Taking the G key and the F key as examples, when in the G mode, all 8 sound holes of the F key are sealed by the sealed end of the mode conversion connecting tube Ⅳ, while the fundamental sound holes and auxiliary sound holes of the F key are in the open state. Since the fundamental sound holes and auxiliary sound holes of the F key are far from the U-shaped blowing port 1, they do not affect the pitch of the G key; when in the F mode, the sound hole tube Ⅱ rotates 180° along the axis, the F key sound holes are in the working state, the 8 sound holes of the G key are in the closed state, and at the same time, the other end of the fundamental sound hole tube Ⅲ is connected to the mode conversion connecting tube Ⅳ, so that the fundamental sound holes and auxiliary sound holes of the F key are in the working state, and the fundamental sound holes and auxiliary sound holes of the G key do not affect the pitch of the F key because they are far from the U-shaped blowing port 1.
