Description

TECHNICAL FIELD

[0001] The utility model relates to ethnic musical instrument technical field, concretely relates to a tujia improved dongdong qin. BACKGROUND

[0002] Dongdong qin is a tujia characteristic national musical instrument, is tujia single reed vertical blowing musical instrument, traditional dongdong qin adopts hollow plant such as single node bamboo to make, the top end of single node pipe body leaves node, cuts a bevel under the node and splits a sheet as tongue reed, three or four press tone holes and a fundamental hole are opened on the pipe body, the air inlet hole is opened below the opposite tongue reed, the lower end of pipe body is cut off as the air outlet of sound production.

[0003] Since the tongue reed is the sheet that is manually cut out with a blade on the plant pipe body, the length and thickness are difficult to control, the yield is low, and it is also easy to damage and difficult to store. The sound quality and tone are difficult to control on the same pipe body.

[0004] The existing tongue reed is usually of a rectangular structure, so in the process of sound vibration, the moving inertia is large, the air inlet hole is easily closed, and sound cannot be produced. In addition, the fingering hole of the existing dongdong qin is usually a V-shaped notch or a rectangular notch formed by simple cutting, and in the process of blowing, the finger pad is not easy to completely close the corresponding fingering hole, and the problem of air leakage due to the closing of the fingering hole is likely to occur, thereby causing the simulated sound to be inaccurate. UTILITY MODEL CONTENTS

[0005] The utility model provides a tujia improved dongdong qin, the improved reed reduces the mass of the free end, thus reducing the moving inertia, in the process of vibration and sound production, it is like human tongue, thereby making the sound more crisp and pleasant, the airflow rotation is more agile, and the higher vibration frequency also makes the reed dry, not easy to make the reed close by itself, and keeps the reed vibrating powerfully. The fingering hole of the circular hole structure can more conform to the dance of the human finger joints, make the fingering hole close more tightly, will not affect the performance effect due to air leakage, and the simulated sound is more lively and lifelike.

[0006] In order to achieve the above purpose, the utility model provides the following technical scheme: a tujia improved dongdong qin, which comprises a main body, the main body is a vertically placed straight pipe structure, and a sealing head is arranged at the top end; the main body is provided with an air inlet window below the sealing head, and a reed is arranged outside the air inlet window and extends downward; the free end of the reed is in an isosceles triangle structure and is arranged on the outside of the air inlet window through the top corner position; and a plurality of fingering holes are arranged on the outer wall of the main body and are communicated with the inside.

[0007] Preferably, each of the fingering holes is of a circular hole structure.

[0008] Preferably, the sealing head and the reed are integrated with the main body.

[0009] Preferably, the sealing head, the reed and the main body are integrally processed in a bamboo joint.

[0010] Preferably, the fingering hole includes a plurality of first eye holes distributed on the front side of the main body in a right-hand type.

[0011] Preferably, the fingering hole includes a plurality of second eye holes distributed on the right side of the main body in a left-hand type.

[0012] Preferably, the fingering hole includes a plurality of third eye holes distributed on the left side of the main body in a right-hand type.

[0013] Preferably, the fingering hole can be divided into three holes, four holes, and six holes in number.

[0014] The improved reed reduces the mass of the free end, thereby reducing the moment of inertia. In the process of trembling and sounding, it is as if the tongue of a person, thereby making the sound more crisp and pleasant, the airflow rotation more agile, and the higher vibration frequency also easy to keep the reed dry, not easy to make the reed self-seal, and keep the reed vibrating powerfully. The circular hole structure of the fingering hole can more conform to the dancing of the human finger joints, make the fingering hole more tightly closed, not affect the playing effect due to air leakage, and make the simulated sound more lively and lifelike. In addition, the dongdongqi can be played according to the habit of a right-hand player by opening a plurality of first eye holes on the front side of the main body, can be played according to the habit of a left-hand player by opening a plurality of second eye holes on the right side of the main body, and can be played according to the habit of a right-hand player by opening a plurality of third eye holes on the left side of the main body. Thus, the distribution and customization requirements of the fingering hole can meet the needs of players with different habits. BRIEF DESCRIPTION OF DRAWINGS

[0024] The technical scheme of the utility model will be described clearly and completely below in conjunction with the drawings of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the person skilled in the art without creative labor belong to the protection scope of the utility model.

[0025] According to Figure 1 As shown in the figure, a Tujia improved dundun, which comprises a main body 1, the main body 1 is vertically placed straight pipe structure, and the top end is provided with a sealing head 2; the main body 1 is provided with an air inlet window 4 below the sealing head 2, and the air inlet window 4 is externally provided with a reed 3 extending downward; the free end of the reed 3 is in isosceles triangle structure, and is clamped on the outside of the air inlet window 4 through the top corner position; the outer wall of the main body 1 is further provided with a plurality of finger holes communicating with the inside.

[0026] Through the above setting, the improved reed 3 reduces the mass of the free end, thus reducing the moment of inertia, and in the process of tremor sounding, it is like a human tongue, so that the sound is more crisp and pleasant, the airflow rotation is more agile, and higher vibration frequency also makes the reed 3 dry, not easy to make the reed 3 self-seal, and keeps the reed 3 vibrating powerfully.

[0027] In another improvement, the finger hole is a round hole structure, which can more conform to the dance of human finger joints, make the finger hole more tightly closed, not affect the playing effect due to air leakage, and simulate more vivid and lifelike sound.

[0028] The sealing head 2 and the reed 3 are both integral structure with the main body 1, and the sealing head 2, the reed 3 and the main body 1 are processed in one piece.

[0029] In addition, according to Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 ,Figure 6 、 Figure 7 As shown in the drawings, the distribution of the fingering holes of the Tujia improved dundunqin is various, a plurality of first eye holes 5 can be opened on the front side of the main body 1 according to the habit of the right-handed player during production and manufacturing; a plurality of second eye holes 6 can be opened on the right side of the main body 1 according to the habit of the left-handed player; and a plurality of third eye holes 7 can be opened on the left side of the main body 1 according to the habit of the right-handed player. Thus, the distribution of the fingering holes can be customized to meet the needs of players with different habits. The number of the fingering holes can be three, four, six and other specifications, so that not only the traditional tune cards can be met, but also more fingering holes can be used to play more extensive folk music, so that the sound is more sweet and melodious, and the effect of the range expansion is achieved.

[0030] The above merely illustrates the specific implementation of the present application, but the protection scope of the present application is not limited to this. Any person skilled in the art can easily think of changes or replacements within the technical range disclosed by the present application, which should be covered by the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
