Description

A kind of wooden pronunciation board Chinese fiddle

Technical field:

The utility model relates to a kind of musical instrument that can play out music rhythm, particularly a kind of wooden pronunciation board Chinese fiddle (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 commonly used 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, qin skin, qin holders, and its annex comprises bow, string, qin sign indicating number, corollary apparatus such as very heavy.In the existing Chinese fiddle, its main parts all adopt type of wood and bamboo materials processing to form, and have 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, the qin tube generally adopts bigger wood materials of density or metal material through being processed into tubular structure in the existing Chinese fiddle.The material of qin tube and qin skin and planform affect the tonequality of urheen bullet when drawing, so the contour structures of qin tube also is very exquisite, 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 at present; And the material-structure of qin skin also is a key factor that influences the Chinese fiddle voice quality, and medium-to-high grade urheen generally selects for use python skin to make.Along with the increase year after year of high density wood bamboo wood material and python skin price and the minimizing of resource, the cost of 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.In addition, the tonequality quality of Chinese fiddle depends on the process technology of raw-material quality, qin tube and the technology of Qin Pi and the assembling of qin tube to a great extent, and these 3 also is one of high reason of present Chinese fiddle manufacturing cost.

Summary of the invention:

The purpose of this utility model is to improve existing Chinese fiddle, particularly used raw-material selection in the urheen, seek the qin tube that a kind of density metal material processing close with high-quality timber made various construction profile, select for use the timber or the bamboo wood of pronunciation high-quality to make the alternative python skin of pronunciation board simultaneously, this can reduce the cost cost of Chinese fiddle, can improve voice quality again, also being easy to mechanization produces in batches, overcome existing Chinese fiddle, particularly the manual difficult processing of qin tube is to guarantee the unified shortcoming of voice quality.Replace python skin with wooden pronunciation board, also have green environmental protection.

For the purpose that realizes that foregoing invention is created, the utility model particularly improves urheen existing Chinese fiddle, manufactures a kind of novel Chinese fiddle.The sound of Chinese fiddle is by the vibration of bow friction string, conducts to Qin Pi or pronunciation board by the qin sign indicating number then to cause what the sympathetic response of qin tube formed.Agent structure of the present utility model is mainly formed by scroll head, qin axle, very heavy, qin bar, bow stick, bow hair, string, Metal musical instrument tube, wooden pronunciation board, qin sign indicating number and qin holder combine and assemble.Scroll head and qin bar are processed into one, and 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 Metal musical instrument tube selects for use metal material processing to make, its contour structures is a tubular, the two ends internal orifice dimension is inequality, wherein fixedly dock the diameter of a close end greater than the other end with the qin bar, wooden or the bamboo matter pronunciation board of closed cover system on the big end qin tube of diameter, corresponding bottom outside with qin bar junction on the Metal musical instrument 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 conventional material to make.

The utility model adopts metal material to substitute the qin tube that Chinese fiddle is made in type of wood and bamboo materials processing, particularly make the qin tube of urheen, and select for use wooden or bamboo material is processed into pronunciation board, identical shaped qin tube and pronunciation board manufacture difficulty had both been reduced, reduced cost, the characteristics that can make full use of the easy casting of metal material are again made the qin tube of contour structures excellence; Also utilized timber to be convenient to increase and decrease thickness, the characteristics that are easy to scribe are made the reliable quality pronunciation board, thereby have guaranteed the unification of Chinese fiddle quality.
