Abstract

The utility model relates to a violin whose back board and lateral board are made of a plurality of half coconut shells. Due to the impacts from growth ring, the early and late wood and other factors, the maple wood conventionally for making the violin characterizes with anisotropy in acoustic property, which reduces the resonance effect of the sound box. However, as the coconut shell has no growth ring, dense and even texture and isotropy in acoustic property, the back board and lateral board of the violin made by coconut shell can well receive the vibration from the panel and resonate with the latter, thus making the tone of the violin more clear, more elegant and brighter. What is more, by making the back board and lateral board of violin with coconut shell, the wood resources can be saved and the cost for making violin can be greatly reduced.

Description

The violin that a kind of backboard and side plate are made of cocoanut shell

Technical field

The utility model relates to a kind of violin.

Background technology

" People's Republic of China's light industry standard instrument volume " regulation, violin backboard and side plate adopt maple wood species or other approximate seeds of material.Use at present maple more.

Maple wood, timber such as maple, because the annual ring influence of factor such as late wood early, acoustic properties presents anisotropy, the ratio that sound wave at its rift grain, radially reaches the propagation rate on tangential is 15: 5: 3.This sound wave along the difference of different directions propagation rate, has not only weakened the sympathetic response effect of violin in timber, and causes the wolf sound easily.

Cocoanut shell is the good musical instrument manufactured materials of a kind of acoustic quality, and the coconut palm Hu Yinse that makes of cocoanut shell is mellow and full, soft, simple and honest; The bowed stringed instrument with a thin wooden soundboard of making of cocoanut shell then pronounces loud and sonorous, loud, and penetration power is strong.

Summary of the invention

The technical problems to be solved in the utility model is, and is better with a kind of acoustic quality, acoustic properties isotropy, and the backboard and the side plate of cheap material violin, and with tonequality, the tone color of improving violin, it is purer to make it sounding, more graceful.

For realizing the above-mentioned technical matters that will solve, the technical scheme that the utility model proposes is: make violin backboard and side plate with the cocoanut shell splicing.Choose several (optional three of violin) size to fits (two bigger, middle is less), plentiful and straight cocoanut shell, after the sawing of middle part, get its top (no nose end), remove the attachment of surfaces externally and internally, polishing is spliced into backboard together with side plate to suitable thickness.

The violin that this backboard and side plate are made of cocoanut shell by panel (above offer sound hole), fingerboard, string hanging plate, neck, side plate together with backboard, string, qin sign indicating number, be the post to which the strings of a musical instrument are attached, pintle, scroll head (drawing) and peg formations such as (drawing).During performance pintle is hung on the knot.

Beneficial effect: maple wood, timber such as maple, because the annual ring influence of factor such as late wood early, its acoustic properties presents anisotropy, thereby has weakened the resonance effect of violin audio amplifier.Cocoanut shell does not have annual ring, and dense materials is and even, and acoustic properties presents isotropy, with the violin backboard and the side plate of its making, can accept the vibration from panel better, and resonance with it, thereby makes violin tonequality purer, and is brighter, more graceful.

With the violin that cocoanut shell splicing is made, the backboard of audio amplifier and the connecting portion of side plate are curved, make the audio amplifier cavity shape be similar to several spheroids that join, and spherical cavity helps vibrating than the cavity of other shape, can obtain better sympathetic response effect.In addition, backboard and side plate one help transfer of vibration, and then help the generation of sympathetic response.

With the violin that cocoanut shell splicing is made, the middle part of audio amplifier, promptly the side plate evagination at sound hole position makes that the intracavity sidewall at sound hole position is rounded, and circular cavity helps vibration than the cavity of other shape, can obtain better sympathetic response effect.

In addition, make violin backboard and side plate, both can save timber resources, can significantly reduce the violin cost again with cocoanut shell.

Description of drawings

Fig. 1 is the utility model by the violin backboard of three the coconut half shells splicings front view together with side plate;

Fig. 2 is the utility model by the violin backboard of three the coconut half shells splicings left view together with side plate;

Fig. 3 is the front view of the utility model violin (scroll head, qin axle do not draw);

Fig. 4 is the left view of the utility model violin (scroll head, qin axle do not draw).

1 panel, 2 fingerboards, 3 sound holes, 4 string hanging plates, 5 necks, 6 side plates are the post to which the strings of a musical instrument are attached, 10 pintles together with backboard, 7 strings, 8 qin sign indicating numbers, 9 among the figure.

Embodiment

Fig. 1 and Fig. 2 have described the violin backboard that is spliced by three coconut half shells together with side plate.Backboard and side plate one, its connecting portion curved (common violin backboard is that the right angle is connected with side plate); The middle part of audio amplifier, promptly the side plate at sound hole position is evagination (the middle part side plate of common violin audio amplifier is an indent).

The diameter of three coconut half shells is following maximum, and top takes second place, middle minimum; Three cocoanut shell cavitys are the thickest with the centre, up and down two thin slightly; Each the position polishing of splicing rear chamber is to suitable thickness (being advisable with the thickness requirement that meets common violin backboard, each position of side plate).

Fig. 3 and Fig. 4 have described the violin (scroll head and qin axle do not draw) that the backboard that is spliced into cocoanut shell is made together with side plate.Offer sound hole 3 on the panel 1, panel 1 constitutes audio amplifier with backboard together with side plate 6; The lower end of neck 5 is connected with the upper end of audio amplifier.

Claims

1. the violin made of cocoanut shell of backboard and side plate is characterized in that backboard and side plate are spliced with cocoanut shell.

2. the violin that a kind of backboard according to claim 1 and side plate are made of cocoanut shell is characterized in that the connecting portion of backboard and side plate is curved.

3. the violin that a kind of backboard according to claim 1 and side plate are made of cocoanut shell is characterized in that, the middle part of violin audio amplifier, and promptly the side plate at sound hole position is an evagination.
