Description

Three sound board resonant type Hu-chin (Chinese violin)

A kind of national musical instruments of playing or accompanying usefulness---three soundboard resonant modes leather recklessly.

National musical instruments are Sinitic bright bright name pearls.Developing national musical instruments is the historic responsibility of the Chinese nation.

In the national musical instruments, there was not desirable bass all the time in the past.National orchestra often uses violoncello to serve as the basso musical instrument, makes national orchestra always have sorry that this makes us being satisfied with.Utilize the urheen principle that urheen is reformed into the trial recklessly of the big leather of the straight sign indicating number of lever formula in order to solve the problem of bass in the national musical instruments, once to have.Big leather after the reform has played the effect of bass national musical instruments recklessly in a way.But because the big leather of the straight sign indicating number of lever formula adopts veneer or single-skin drum vibration pronunciation recklessly, the acoustic frequency response limitation is very big, can only reflect the audio frequency vibration in one, two range of sound effectively, can not make high, medium and low each range of sound of waiting all obtain gratifying effect, so still can not fully satisfy in the national orchestra needs to bass.

The purpose of this utility model is to design a kind of three soundboard resonant modes leather recklessly on the big leather of the straight sign indicating number of lever formula basis recklessly, make it gratifying acoustic frequency response all be arranged, thereby can satisfy the needs of bass in the national orchestra more fully in high, medium and low each range of sound of waiting.

Fig. 1 is a principle schematic of the present utility model, also is that specification digest is with scheming; Fig. 2 is a front view of the present utility model; Fig. 3 is a side view of the present utility model.Each label is respectively among the figure: 1 scroll head, 2 string groove caskets, 3 pegs, 4 fingerboards, 5 sound holes, 6 yards bridges, 7 preceding soundboards, 8 qin tubes, 9 chord-drawing plates, 10 times jack rafters, 11 qin pin, 12 sidetone plates, 13 tooth shape axles, soundboard bass bar before 14,15 turn to a yard pin, 16 sidetone plates, 17 sound columns, 18 back soundboards, 19 resonance tubes, 20 necks, jack rafter on 21,23 strings, 24 end cap sound windows, 25 high pitch sign indicating number pin, 26 bass sign indicating number pin.

As shown in the figure, the utility model is made up of scroll head 1, neck 20, qin tube 8, peg 3, fingerboard 4, code bridge 6, string 23, wherein qin tube 8 one ends are the sidetone plate of gross area formula, the other end arranges a sympathetic response tube 19 with the vertebra degree at the inboard center of sound window 24, the qin tube 8 positive outsides are front soundboard 7, and the inside of a corresponding side with it arranges a rear soundboard 18, and code bridge 6 is double-legged formula code bridge, high tone code pin 25 is supported on the front soundboard 7, front soundboard 7 back sides and the strong point Corresponding some upper support one sound column 17, the other end of sound column 17 is supported on point corresponding to rear soundboard, low tone code pin 26 is overlapped on the front soundboard bass bar 14 by tooth shape axle 13, and summit hinge form is connected with turning to 15 one-tenth 90 ° on yard pin, turns to yard pin 15 and sidetone plate sound beam 16 dynamically to join. Rear soundboard 18 bridge-type rigidity are shelved on the circular bracing ring.

Principle of work of the present utility model is as follows: when the player spurred bow generation moving string vibration, yard bridge 6 was passed in the vibration of string, bass sign indicating number pin 26 up-down vibration, and soundboard 7 up-down vibration pronunciation before driving is simultaneously by turning to yard pin 15 to drive 12 pronunciations of sidetone plates; High pitch sign indicating number pin 25 is static relatively, and by sound column 17 back soundboard 18 is passed in vibration, because three pronunciation boards derive from same vibration source, so but harmony vibration.The vibration that the vibration of three soundboards promotes air in the qin tube produces the tube sympathetic response that is equal to urheen and has urheen and the tone color of violin characteristics.

The leather that uses the utility model to make can combine the two plate resonance of violin with Chinese fiddle recklessly in phase, three soundboards pronounce simultaneously during use, increased leather volume recklessly, improved sound quality effectively, it is bass desirable in the national orchestra, having filled up the blank that does not have bass in the national orchestra, is the major contribution to national culture, and very important promotional value is arranged.

Embodiment:

Scroll head 1 is to 2 times length of side 277mm of string groove casket, the long 392mm in string groove casket 2 bottoms to qin case 22 upper ends, and qin case 22 upper ends are to sign indicating number bridge 6 long 285mm, qin case 22 long 600mm, wide 275mm, high 260mm, sidetone board are divided into urheen district part, and diameter is 540mm, high 145mm, the preceding long 460mm of soundboard, wide 250mm, thick 2mm, the high 75mm of soundboard 7 upper parts before the bridge sign indicating number 6, bass pin 26 long 140mm, diameter 4mm turns to yard pin 15 long 90mm, diameter 4mm, sound column 17 long 260mm, diameter 4mm, resonance tube diameter small end 100mm, big end 120mm, high 200mm.Material is a wood materials.
