Ceramic Erhu

Abstract

The invention discloses a ceramic Erhu, which comprises an Erhu cylinder, an Erhu rod, an Erhu shaft, an Erhu bridge, an Erhu bracket and the like, wherein the Erhu cylinder, and / or the Erhu rod, and / or the Erhu shaft, and / or the Erhu bridge, and / or the Erhu bracket are sintered and molded by fiber-reinforced ceramics. According to the present invention, by adding the high-strength ceramic fibersto the ceramic, the strength and the toughness of the ceramic are greatly improved; and compared with the traditional wooden Erhu, the Erhu of the present invention has the following characteristics that the Erhu body is not affected by the temperature, the humidity and the fatigue stress, the environment induced Erhu sound quality change cannot be generated, the water absorption rate and the expansion rate are extremely low, the material is fine, the physical properties at each place are uniform, the sound effect of the Erhu is consistent, the tuning time of the performer can be reduced, thestable and rich sound quality can be achieved compared with the traditional wooden Erhu body, and the playing effect of the Erhu is improved.

Description

technical field [0001] The invention relates to a musical instrument and a preparation method thereof, in particular to a fiber-reinforced ceramic erhu and a preparation method thereof. technical background [0002] It is known that the erhu began in the Tang Dynasty and is called "Xiqin", also known as Erxian Huqin, "Nanhu" and "Omzi". It has a history of more than one thousand years and is one of the traditional Chinese stringed instruments. Repertoires such as Erquan Yingyue and horse racing are deeply loved by the masses. The traditional erhu generally includes wooden qin tubes, qin rods, qin bows, qin shafts, strings, qin skins, daughters, metal qin holders, bridges, etc. [0003] The qin tube is covered with a qin skin and sound holes are set, and the sound is produced by the friction between the bow and the strings. However, because the wooden qin tube and the qin rod are greatly affected by the environment, for example, they are easily affected by temperature, humid...

AI Technical Summary

Problems solved by technology

[0003] The qin tube is covered with a qin skin and sound holes are set, and the sound is produced by the friction between the bow and the strings. However, because the wooden qin tube and the qin rod are greatly affected by the environment, for example, they are easily affected by temperature, humidity, etc., resulting in erhu playing. The change of the sound can not guarantee the consistency of the playing effect, which affects the playing of the musical instrument. Therefore, the above problems need to be solved urgently.

[0004] Liu Deming applied to publish a kind of erhu (CN 107886932 A) in 2017. The qin bar and the qin tube are carved from She Tai emerald jade, but the engraving process is used, which is costly and difficult to prepare, and is not easy to mass produce

And the price of jade is high, which increases the price of erhu

Limited colors limit the form of expression

[0005] Therefore the applicant intends to develop a kind of erhu with a stable structure, which is not easily affected by temperature and humidity, and eliminates the shortcomings of conventional erhu colors and monotonous decorations, and develops a ceramic erhu fired by ceramic technology. Fired ceramic products are weak in impact resistance and bending resistance, and are prone to breakage and fragmentation, especially for products or components with relatively large length and diameter (such as piano bars)
