Abstract

The utility model relates to a sound pipe of a reed pipe musical instrument, in particular to a main sound pipe structure of cucurbit flute and Bawu musical instruments in reed pipe musical instrument. The end part of the main sound pipe is provided with a languette. The main sound pipe is provided with seven sound holes, six sound holes arrange at the positive face and one sound hole arranged at the back face. Middle and low sound holes on the main sound pipe move towards the direction of the languette, and all moved sound holes are internally inserted with a pillar canal. The length of the pillar canal is the distance of the sound hole moving towards the direction the languette. The sound pipe has the beneficial effects that: as the main pipe is additionally provided with the pillar canal, the pattern sound can be effectively closer; in the condition of unchanging the model of the original cucurbit flute, the player does not feel any difference and can play freely to make beautiful musical composition. The structure is simple, and the design is scientific and reasonable.

Description

The keynote tubular construction of cucurbit silk and crust crow

Technical field

The utility model relates to a kind of sound pipe of reed pipe musical instrument, particularly relates to cucurbit silk in a kind of reed pipe musical instrument and clings to the keynote tubular construction of black musical instrument.

Background technology

Cucurbit silk, crust crow are the reed pipe musical instruments of Chinese Minority Nationalities, its tone color grace, profile is peculiar and be subjected to liking of people, traditional cucurbit silk, crust crow have seven sound holes, positive six sound holes of keynote pipe, the sound hole in the back side, low part during traditional cucurbit silk, crust crow lack, reason be in the wind instrument finger-hole or the sound hole of low part to change along with the variation of musical instrument self pitch, promptly, distance between the low more sound hole of the musical instrument sound position is far away more, finger can't accurately be held, and Fig. 1 is a traditional instrument keynote pipe sound hole position view.The musical instrument of sound hole distance as shown in Figure 1, for example bass D, C, falling B, A, G etc. can be considerably less with the player that above mode musical instrument normally uses, main cause is that the sound hole spacing is excessive, finger can't be by due to the hole, it is to address this problem normal employing to add key apparatus and remedy the requirement of player's finger to musical instrument that some basses are also arranged now, but lost the basic playing technique of national musical instruments, for example glide, folded sound, appoggiatura, add the key musical instrument and can't play, national musical instruments are looked more look like western musical instrument.Another kind is a pillar perforate method outside adopting on being responsible for, the phoneme though can further, this mode can not arbitrarily be used because once the sound hole spacing to draw in when too much column jacket too high naturally, sensitivity and dexterity when influencing player's finger by the hole have also changed the original outward appearance of cucurbit silk simultaneously.

Summary of the invention

Technical problem to be solved in the utility model is, provide a kind of in the sound hole spacing of bass cucurbit silk, crust crow can arbitrarily further to the required optimum position of player, make performance more flexible, and do not influence musical instrument self outward appearance.

The technical scheme that the utility model adopted is: the keynote tubular construction of a kind of cucurbit silk and crust crow, and the end of keynote pipe is provided with languid, has seven sound holes on described keynote pipe, positive six sound holes, the sound hole in the back side; Move to the languid direction at described keynote Guan Shangzhong, low sound hole, all be inserted with a column jecket in all sound holes that are moved.

Described column jecket length is sound hole to the distance that languid side moved.

Described column jecket is hollow pipe or Sui Yuan shape pipe, and the pairing internal diameter of its external diameter and sound hole is suitable, and the axis of described column jecket is vertical with the axis of keynote pipe.

Described front sound hole point-blank or interlaced arrangement between the sound hole of front.

Described column jecket can be selected metal, nylon plastic(s) or PVC material for use.

The beneficial effects of the utility model are: owing to install column jecket additional in being responsible for, the phoneme that can effectively further is under the situation that does not change the moulding of original cucurbit silk, player's feel does not have any difference, can play freely, blow out graceful melody, this is simple in structure, design science is reasonable.

Embodiment

Below in conjunction with the drawings and specific embodiments the utility model is described in further detail:

As Fig. 2-shown in Figure 3, the keynote tubular construction of the utility model cucurbit silk and crust crow, languid 200 is arranged on the end of keynote pipe 100, on described keynote pipe 100, have seven sound holes, positive six sound holes, the sound hole in the back side, described front sound hole can be arranged point-blank, arrangement between the sound hole of front also can be not point-blank, as can interlacedly arranging; Described keynote pipe 100 is keynote pipes of cucurbit silk or crust crow; On described keynote pipe 100, in, low sound hole moves to languid 200 directions, the sound hole 300 that moves all is inserted with a column jecket 400.Described column jecket 400 is hollow circular-tube or Sui Yuan shape pipe, and its external diameter and pairing sound hole internal diameter are suitable, and the axis of described column jecket 400 is vertical with the axis of keynote pipe 100.Described column jecket 400 length are the distance that sound hole 300 is moved, and promptly middle sound hole 3 moves X mm to the languid direction, and the height of its column jecket is X mm; Middle sound hole 2 moves X1mm, and the height of its column jecket is X1mm; Low sound hole 7 moves X2 mm to the languid direction, and the height of its column jecket is X 2mm; Low sound hole 6 moves X3mm, and the height of its column jecket is X3mm.Described column jecket 400 can be selected metal, nylon plastic(s) or PVC material for use.

Embodiment 1: when middle pitch 3 moves 8mm to the languid direction, the height of its column jecket is 8mm; Middle pitch 2 moves 7mm to the languid direction, and the height of its column jecket is 7mm; When bass 7 moves 6mm to the languid direction, the height of its column jecket is 6mm; Bass 6 moves 5mm to the languid direction, and the height of its column jecket is 5mm; The external diameter of the above column jecket internal diameter of the sound hole corresponding with it respectively is suitable.

The high pitch 6 of cucurbit silk or crust crow, 5 phonemes, middle pitch 1 bass 3 is still at the invariant position (also can arbitrarily change the position) of traditional cucurbit silk if needed, requirement according to the player, promptly, the distance of required sound hole is determined

middle pitch

2,3 and

bass

6,7, can according to all ages and classes not the player of homochirality carry out free perforate, middle pitch 2 after the free perforate, 3

basses

6,7 accuracy in pitch that can occur in various degree are higher, need accurately to calculate respectively middle pitch 2 this moment, 3 and

bass

6,7 upwards move the gap of sound hole and conventional size, and calculate the actual diameter of sound hole, can accurately calculate the external diameter and the height of column jecket this moment, at last the cucurbit silk is carried out tuning, the cucurbit silk that makes by the as above method sound hole distance that effectively furthered makes the player can play middle bass melody in the ideal freely.

It is worthy of note; protection domain of the present utility model is not limited to above-mentioned instantiation mode; according to basic fundamental design of the present utility model; also available identical structure to other reed pipe musical instrument by in sound hole, installing column jecket additional; shorten the sound hole spacing, still can realize the purpose of bass melody in this novel performance freely, as long as those of ordinary skills need not through creative work; the embodiment that can associate all belongs to protection domain of the present utility model.
