Abstract

A duplex coat of huqin, whose structure is characterized in the coat containing two layers of snakeskin that are outer layer snakeskin and endoderm snakeskin bonded by glue layer in middle, pattern of the inner, out layer snakeskin is vertical, overall thickness of two layers of snakeskin is 0.13-0.2 mm. Comparing with traditional coat of huqin, the utility model has strong endurance, do not easy break and easy to get needed thickness, utilizing thinner snakeskin to reduce waste of snakeskin resource, and bilayer snakeskin accepts force uniformly and not easy to generate noise, not only keeping traditional style of huqin, but also improve sound quality.

Description

Double membrane for Huqin

Technical field

The utility model relates to the stringed musical instrument with qin skin, particularly relates to a kind of qin skin structure of Chinese fiddle.

Background technology

The Chinese fiddle that urheen, jinghu etc. have the qin skin is the modal national musical instruments of China, and the traditional fabrication method of its qin skin is to adopt individual layer snakeskin (or boa skin) fasten hide or leather on the qin tube.Because the became uneven of snakeskin own; Chinese fiddle is easy to generate noise; want to make the good Chinese fiddle of voice effect, must use bigger snakeskin, but wild snake or boa have been listed in and have watched for animals; raw material is rare; and one snakeskin is more and more thinner from the afterbody to the head, and thickness does not reach 0.13mm and promptly loses value, thereby the utilization factor that makes snakeskin is less than 50%; cause the significant wastage of resource, and manufacture difficulty is bigger.Be that its pulling force gap horizontal and that vertically can bear of this qin skin is bigger again, break easily in the use.For addressing the above problem, application number, is difficult for breaking though raw material is easy to get for 200410103555.5 patented claim provides a kind of qin skin that utilizes plastic sheet or sheet metal to make, and has also lost traditional acoustics of Chinese fiddle.

Summary of the invention

The purpose of this utility model is exactly at the deficiencies in the prior art, a kind of snakeskin utilization factor height is provided, is difficult for breaking, phonogenic Chinese fiddle qin skin.

The utility model double membrane for Huqin, its design feature are that this qin suitcase is drawn together outer snakeskin and the two-layer snakeskin of internal layer snakeskin, and inside and outside two-layer snakeskin is bonded together by the adhesive-layer of centre, and the lay of inside and outside two-layer snakeskin is vertical.

Double membrane for Huqin as mentioned above, the gross thickness after its two-layer snakeskin is bonding is 0.13-0.2mm.

With the skin-deep ratio of traditional Chinese fiddle qin, the utlity model has following advantage: the one, make compound qin skin owing to the vertical inside and outside two-layer snakeskin of employing lay is bonding, the intensity height is difficult for breaking long service life; The 2nd, double-deck snakeskin is easy to reach desired thickness, can make thin snakeskin obtain utilizing, thereby the utilization factor of snakeskin is brought up to more than 85%, has significantly reduced the waste of snakeskin resource, has reduced production cost; The 3rd, double-deck snakeskin is stressed evenly in all directions, be difficult for producing noise, and it is clear and melodious to pronounce, and has both kept the traditional style of Chinese fiddle, has improved voice quality again.

Embodiment

The accompanying drawing illustrated embodiment, the utility model double membrane for Huqin comprises outer snakeskin 1 and internal layer snakeskin 2 two-layer snakeskins, inside and outside two-layer snakeskin is bonded together by the adhesive-layer 3 of centre.The lay of inside and outside two-layer snakeskin is vertical, and promptly the lay of inside and outside two-layer snakeskin is pasted at an angle of 90.Adhesive-layer 3 can adopt 302 rubber polymers.Gross thickness after two-layer snakeskin 1,2 is bonding is 0.13-0.2mm.

Claims

1, a kind of double membrane for Huqin, it is characterized in that this qin suitcase draws together outer snakeskin (1) and the two-layer snakeskin of internal layer snakeskin (2), inside and outside two-layer snakeskin (2) (1) is bonded together by middle adhesive-layer (3), and the lay of inside and outside two-layer snakeskin (2) (1) is vertical.

2, double membrane for Huqin according to claim 1 is characterized in that the gross thickness of two-layer snakeskin (1) (2) after bonding is 0.13-0.2mm.
