Description

Compound template violin

Technical field

The utility model belongs to wooden musical instrument, and particularly violin is made the field.

Background technology

Violin comprises violoncello, viola, violin, and it is world-famous for by force with tonequality grace, range broadness, expressive force.The quality of violin tonequality depends on wood quality on the one hand, and the also main on the other hand size shape by the sympathetic response housing is determined (comprising the problem of manufacture craft in addition).This sympathetic response housing is made up of panel and backboard and side plate.Because vibrations of strings is the vibration that directly is transformed into panel by the string sign indicating number, and by the pronunciation of sympathetic response housing, so especially the selection and the making of panel are the key factors of decision violin acoustic quality quality to the sympathetic response housing.On traditional manufacturing technique, curved panel and backboard all are to adopt the solid wood jigsaw, basically by the manual type of making that digs.Thereby there is the shortcoming that weather resisteant is poor, cost is higher first in existing violin.Owing to climate change or geographic position change the variation of the temperature and humidity that causes, this solid-wood panels and backboard are deformed easily and the ideal state of vaulted sounding diaphragm can not keep modulating at first the time; Secondly, curved panel, backboard adopt by hand and dig the type of making, and production efficiency is low, can not accomplish scale production.

The utility model content

Task of the present utility model is to provide a kind of compound template violin, and it has weather resisteant and processing characteristics preferably.This task realizes by following design: a kind of compound template violin, comprise scroll head, and neck, by the sympathetic response housing that panel, backboard, side plate are formed, fingerboard and tailpiece is characterized in that, described panel is double-deck special-shaped thick china; The upper epidermis of this panel is a quarter sawing dragon spruce veneer, and its texture trend vertically is provided with by body; Described backboard adopts two-layer above odd-level veneer to move towards crisscross assembly by the grain of wood and arranges moulded glued moulding.

A kind of compound template violin, comprise scroll head, neck is by the sympathetic response housing that panel, backboard and side plate are formed, fingerboard and tailpiece, it is characterized in that, described panel adopts two-layer above odd-level veneer, and its texture trend is arranged the glue laminated moulding by the crisscross assembly of body direction, and its upper epidermis veneer is a quarter sawing dragon spruce veneer, and its texture trend vertically is provided with by body; Described backboard adopts two-layer above odd-level veneer crisscross, moulded glued moulding.

From one of above-mentioned design proposal as seen, (with prefabricated profiled arc-shaped curved surface plate is basal plate to adopt double-deck special-shaped thick china as the panel (also claiming soundboard) of one of violin sympathetic response housing significant components, basal plate gluing unification thin type veneer), the upper epidermis of this panel is a quarter sawing dragon spruce veneer, it is vertical (promptly with the direction of string almost parallel that its texture trend press body, down together) (consistent with the way of existing violin panel) is set, the backboard of sympathetic response housing adopt the multilayer veneer (be two-layer more than, do not contain two-layer, down together) (equally for the body direction) is staggered in length and breadth, moulded glued moulding directly forms arc-shaped curved surface.In the above-mentioned design, panel and backboard are respectively two-layer and two-layer above composite plates, have improved whole weather resisteant energy, and backboard adopts the glue laminated mode to form arc-shaped curved surface, has improved processing characteristics, helps the raising of production efficiency.

From above-mentioned design proposal two as seen, its panel adopts the crisscross setting of odd-level veneer, through moulded glued moulding, directly forms arc-shaped curved surface, its upper epidermis is a quarter sawing dragon spruce veneer, the texture trend vertically is provided with by body; Its backboard is identical with one of above-mentioned design proposal, and it is crisscross to be the multilayer veneer, moulded glued moulding.Be not difficult to find out, design proposal two in, panel and backboard all are multi-plywoods, weather resisteant can be improved; Simultaneously, panel and backboard all adopt glue laminated to form arc-shaped curved surface, and processing characteristics also is improved.

Compared with prior art, this novelly has following characteristics and an advantage: 1, straight forming reduces cost and material consumption; 2, two-layer and multilayer gluing, physical dimension is stable, and weather resisteant is good; 3, adopt machining, moulded glued moulding, production efficiency improves, and is convenient to large-scale production.

Embodiment

Fig. 1 illustrates, and violin is mainly by scroll head 3, neck 4, fingerboard 5, tailpiece 6 and panel 1, backboard 2, compositions such as side plate.Wherein panel 1, and backboard 2 and side plate constitute the sympathetic response housing.Above-mentioned panel can adopt two kinds of forms shown in Fig. 2 and Fig. 3 to make.Among Fig. 3, panel is double-deck special-shaped thick china, be that (basal plate is formed plywood or the moulding solid wood plate that satisfies the requirement of violin soundboard curved surface to basal plate 32, the most handy dragon spruce, also can be other seeds) be made into the arc-shaped curved surface plate in advance, its upper epidermis (being the top layer of panel 1 among Fig. 1) gummed one quarter sawing dragon spruce veneer 31, the texture of veneer 31 trend press vertically setting of body (from scroll head, neck to sympathetic response lower part of frame direction), the thick 3-8mm of whole front panel (corresponding large, medium and small violin), veneer 31 thick 0.4-1.5mm.Among Fig. 2, panel adopts two-layer above odd-level veneer as three layers, five layers or seven layers, its texture trend by body in length and breadth the direction assembly arrange, moulded glued moulding, its upper epidermis veneer 11 be a quarter sawing dragon spruce veneer, texture moves towards vertically to be provided with by body; Also can be, the grain of wood of the central core veneer 13 of this panel trend be pressed the body horizontally set, all the other each layer veneers 11,12,14,15 the thick 3-8mm of whole front panel, upper epidermis veneer 11 thick 0.4-1.5mm vertically are set by body.The respective layer veneer of the upper and lower both sides of central core veneer of this panel is the uniform thickness setting respectively, and seeds are identical, and promptly the thickness of veneer 12,14 is identical, and seeds are identical; The thickness of veneer 11,15 is identical, and seeds are identical.Among Fig. 4, backboard adopts two-layer above odd-level veneer as five layers of
