Description

A kind of Metal musical instrument tube urheen

Technical field:

The utility model relates to a kind of musical instrument that can play out music rhythm, particularly a kind of Metal musical instrument tube Chinese fiddle, promptly a kind of Metal musical instrument tube urheen.

Background technology:

Chinese fiddle is a kind of in a series of musical instruments of the Chinese nation, mainly contains several classes such as jinghu, urheen.Urheen is a musical instrument accompaniment general in the Chinese fiddle, and urheen also is called another name for erhu, a two-stringed bowed instrument, and it is mainly constructed is to be combined by main elements such as scroll head, qin bar, qin axle, qin tube, tube skin and qin holders, and its annex comprises bow, string, qin sign indicating number and corollary apparatus such as very heavy.In the existing Chinese fiddle, its critical piece all adopts type of wood and bamboo materials processing to make, and has the materials processing of the nature bone of employing tooth class to make individually, especially the qin tube of Chinese fiddle, because it is the resonant tank of urheen, so the selection quality of its material is determining the quality quality of urheen.Its qin tube generally adopts the bigger wood materials of density through being processed into tubular structure in the existing urheen, the material of qin tube and planform affect the tonequality of urheen bullet when drawing, so the contour structures of qin tube also is very exquisite, at present the Mechanical Builds of qin tube mainly contains six square tubes, cylinder or the like behind tube, cylindroid and the place ahead from all directions.Along with the price increase of high density wood bamboo wood material and the minimizing of resource, the cost of two-stringed Chinese fiddle Chinese fiddle surge at present impacts its universal use, particularly the fan of remote districts, is difficult to take out the income purchase one of nearly more than half a year urheen.The pronunciation quality of wooden in addition bamboo matter qin tube depends on the process technology of raw-material quality and qin tube, and these 2 also is one of high reason of present urheen manufacturing cost.

Summary of the invention:

The purpose of this utility model is to improve used raw-material selection in the existing urheen, particularly seeking the qin tube that a kind of density metal material processing close with high-quality timber made various construction profile, this can reduce the cost cost of urheen, can improve voice quality again, can also be easy to mechanization produces in batches, overcome existing urheen, particularly the manual difficult processing of qin tube is to guarantee the unified shortcoming of voice quality.

In order to realize foregoing invention creation purpose, the utility model is to existing Chinese fiddle, particularly urheen is improved, and manufactures a kind of novel urheen Chinese fiddle.The sound of urheen is by the vibration of bow friction string, conducts to empathize to Qin Pi and qin tube by the qin sign indicating number then to form.Agent structure of the present utility model is mainly formed by scroll head, qin axle, very heavy, qin bar, bow stick, bow hair, string, qin tube, qin tube strip of paper used for sealing, qin sign indicating number and qin holder combine and assemble, scroll head and qin bar are processed into one, qin bar top is arranged and is shaped on interspersed rotatable qin axle, and the low side of qin bar fixedly docks with the qin tube; The qin tube selects for use metal material through being processed into, its contour structures is a tubular, two ends inner core bore dia is inequality, wherein fixedly dock the diameter of a close end greater than the other end with the qin bar, closed cover is shaped on qin tube strip of paper used for sealing on the big end qin tube of diameter, corresponding bottom outside with qin bar junction on the qin tube laterally is shaped on Qin Tuo, and the stability when using to increase reduces assorted shaking; It is very heavy, bow stick, bow hair, string, qin sign indicating number take routine techniques to make.

The utility model adopts metal material to substitute the parts that urheen is manufactured in type of wood and bamboo materials processing, particularly make the qin tube and the qin holder of urheen, both reduced the manufacture difficulty of identical shaped qin tube, reduced cost, the ductility that can make full use of metal is again made qin tube, the especially metal material of contour structures excellence can use foundry engieering processing and preparing qin tube, is convenient to regulate its alloy composition, guarantee the unification of qin tube quality, thereby guarantee the quality of urheen pronunciation.

Description of drawings:

Fig. 1 is a general structure synoptic diagram of the present utility model.

Specific embodiments:

Embodiment 1: enforcement of the present utility model is to existing Chinese fiddle, particularly urheen is improved and finishes, its main element comprises: scroll head 1, qin axle 2, very heavy 3, qin bar 4, bow stick 5, bow hair 6, string 7, qin tube 8, qin tube strip of paper used for sealing 9, qin sign indicating number 10 and Qin Tuo 11, very heavy 3, bow stick 5 wherein, bow hair 6, string 7 and qin sign indicating number 10 all can adopt prior art and materials processing to make, and also can directly purchase in market.Scroll head 1 and qin bar 4 both can be made as the one of homogeneous material, or the split of making different materials is connected into integral structure, its material can be type of wood and bamboo, metal species or plastics class, and qin axle 2 is interspersed in the top of qin bar 4 and can rotates the back and do not drawn pine by string 7 with hand.Qin tube 8 is processed into the structure that profile is six square tubes or all directions tube or cylinder or cylindroid by metal material die casting or with sheet metal, selected density metal should be close with type of wood and bamboo density, magnesium alloy that adopts in the test or zinc alloy material are all received ideal effect, or directly with the processing of gray iron plate.The inner core hole face of qin tube 8 should be smooth flawless, the two ends internal diameter is unequal, wherein 4 pairs on qin bar is inserted the near end diameter of affixed qin tube 8 greater than the other end, and be shaped on qin tube strip of paper used for sealing 9 at the big qin tube end sealing shroud of diameter, qin bar 4 is spiral or the slotting formula of pressure with qin tube 8 to inserting affixed mode, should be difficult for loosening in affixed back, qin tube 8 bottom outside are shaped on qin holder 11, its function can guarantee in use that for making urheen qin tube 8 firmly is difficult for sliding, and guarantee that there are less soft objects such as area contact human body in the qin tube outside, so that the voice quality of urheen is unaffected.
