Abstract

The utility model relates to an improved violin resonance box which is composed of a violin face plate, a back plate, a side plate frame and a sound column. Two F-shaped sound holes are disposed in the violin face plate. A long sound beam is attached onto the back of the violin face plate. A small sub sound beam and a large sub sound beam are disposed perpendicularly on two sides of the long sound beam on the back of the violin face plate in an upper half area of central gaps of the two F-shaped sound holes, and the small sub sound beam is disposed at some distance from the large sub sound beam. Compared with the prior art, the improved violin resonance box enhances the stiffness of the violin face plate through addition of the large and small sub sound beams on the two sides of the long sound beam, can withstand greater stress and tension, is not easily deformed, can further eliminate high-frequency odd harmonics generated in vibration conduction, and thus obtains a full, pure, honest, balanced and sweet sound of a harmonious chord.

Description

Improved violin resonant tank

Technical field

The utility model relates to a kind of musical instrument, more specifically to a kind of improved violin resonant tank.

Background technology

In the prior art, the planform of violin, viola, violoncello and Double bass, the ratio of physical dimension and Mechanism of Speech Production are all identical, and their composition is: body, string system and bow.Wherein body is comprised of scroll head, neck, fingerboard and resonant tank again.Self-evident, the quality of resonant tank has determined that whether the tone color of this qin is graceful.The structure of further analyzing resonant tank is known, and it is comprised of panel, backboard and side plate framework, and from a structural point, violin tightens after string, and qin panel has born very large pressure and tension force, because having the sound hole of two F shapes, just becomes more weak again.For this reason, forefathers have done a large amount of research, have increased a main sound beam below qin panel, improve the force-bearing situation of panel, though obtained good effect, but still imperfect, for eliminating the high frequency odd harmonic producing in conduct vibrations process, still feel not enough.

Utility model content

The purpose of this utility model for prior art weak point, provide a kind of strengthen qin panel stressed, further eliminate the high frequency odd that produces in conduct vibrations process improved violin resonant tank humorous, that reduce cost of manufacture.

The purpose of this utility model is to realize by following measures: a kind of improved violin resonant tank, it is comprised of qin panel, backboard, side plate framework and sound column, two F shape sound holes on described qin panel, have been had, its qin back side of panel posts a main sound beam, its special character is: in first region of breach, described two F shape sound hole centers, qin back side of panel main sound beam both sides arrange respectively perpendicular little secondary sound beam and first mate's sound beam, and little secondary sound beam and first mate's sound beam are at intervals.

Described little secondary sound beam is arranged between main sound beam and F shape sound hole center, right side breach, and its width and main sound beam are wide, and itself and main sound beam contact position and main sound beam are contour, to F shape sound hole indentation, there, reduce gradually.

Described first mate's sound beam is arranged between main sound beam and left side F shape sound hole, and the level interval of itself and secondary sound beam is between 11 ~ 13mm, and its width and main sound beam are wide, and itself and main sound beam contact position and main sound beam are contour, and to F shape sound hole, place reduces gradually.

Compared with prior art, the utility model has increased first mate's sound beam and little secondary sound beam in the both sides of main sound beam, increased the rigidity of qin panel, can bear larger pressure and tension force, be difficult for producing distortion, can further eliminate the high frequency odd harmonic producing in conduct vibrations process, obtain sound full, pure, pure and honest, that balance is melodious, chord is coordinated.

Embodiment

Below in conjunction with accompanying drawing, embodiment is elaborated:

Fig. 1 has provided the structural representation of the utility model embodiment.An improved violin resonant tank, it is comprised of qin panel, backboard, side plate framework and sound column, and innovative point of the present utility model, on qin panel, draws therefore miscellaneous part figure omits.Two F shape sound holes on described panel 1, have been had as seen from the figure, its back side of panel posts a main sound beam 2, first main sound beam both sides, wainscot back side, region of described two F shape sound hole center breach arrange respectively perpendicular little secondary sound beam 3 and first mate's sound beam 4, and little secondary sound beam and first mate's sound beam are at intervals.The present embodiment be take violin as example, little secondary sound beam described in embodiment is arranged between main sound beam and right side F shape sound hole 5 center breach, and its width and main sound beam are wide, and itself and main sound beam contact position and main sound beam are contour, to F v notch v, place reduces gradually, and Fig. 2 is the large sound beam of the utility model side view.The sound of first mate described in the present embodiment beam is arranged on 6 of main sound beam and left side F shape sound holes, the level interval of itself and secondary sound beam is between 11 ~ 13mm, its width and main sound beam are wide, itself and main sound beam contact position and main sound beam are contour, to F shape sound hole, place reduces gradually, and Fig. 3 is the little sound beam of the utility model embodiment side view.

Violin is when work, four strings on violin need be tightened, four strings are respectively G, D, A, E, take E string as example, the tensile force tightening on rear E string is 9 kilograms strong, after G string tightens, tensile force on G string is 6 kilograms, the tensile force of D string and A string falls between, total tension force of four strings has 30 kilograms strong, and qin panel is the shell structure of a perforate, the tensile force of four strings is passed on panel by qin bridge, according to detecting suffered power on panel, reach 11 kilograms strong, once therefore because the rigidity of qin panel is inadequate, slightly distortion is even very trickle distortion will inevitably affect the tonequality of this qin, because the both sides at main sound beam have increased first mate's sound beam and little secondary sound beam, increased the rigidity of the violin source of sound center two formed trigonum of F sound hole qin panels, can bear larger pressure and tension force, and can make the panel of panel and side plate framework junction do again thinnerly, make its amplitude larger, can make like this sound be transmitted to rapidly both sides, after resonance, produce high frequency even-order harmonic, further eliminate the high frequency odd harmonic producing in conduct vibrations process, obtain full, pure, pure and honest, balance is melodious, the sound that chord is coordinated.

Above-described embodiment is not purchased paired restriction of the present utility model, and all employings are equal to replaces or technical scheme that the form of equivalent transformation obtains, within all dropping on protection domain of the present utility model.
