Description

Composite panel of guqin

Technical Field

The application relates to musical instruments, in particular to a guqin.

Background

This section is intended to provide a background or context to the embodiments of the application that are recited in the claims. The description herein is not admitted to be prior art by inclusion in this section.

The head of the Guqin position row 'qin chess painting' is a necessary repair for doctors and doctors in ancient China. And is also a world-level non-material cultural heritage. The inheritance of the guqin is not only reflected in the playing art of the guqin, but also reflected in the manufacturing technology. Since Tang Dynasty, the ancient lyre was made to meet the peak. Many Guqins made in Tang, Song, Yuan, Ming and Qing dynasties have been born alive to the present era for thousands, three and hundreds of years. Wherein, the shape system and the manufacturing process of the Tang ancient seven-stringed harp with thousands of meteorology are completely inherited. Modern guqin makers still use these materials and processes to make excellent guqins.

The guqin is made up of a panel and a bottom plate. The panel arch is a 'sky circle'; the floor is flat and is the "place". Round the upper part and round the lower part, yin and yang are combined. Many independent accessories are arranged on the panel, including a dragon gum, two crown horns, a bearing dew, a mountain and the like.

The Yueshan is positioned below the forehead of the musical instrument and is used for erecting strings. When playing a Guqin, the vibration of the strings can be transmitted to the body through the Yueshan. Therefore, Yueshan is generally made from high quality hardwood. The material and thickness of the mountain and the shape of the key parts have direct influence on the tone.

The dragon gum is arranged in the center of the tail of the musical instrument, and is made of high-quality hardwood to erect strings. The gingiva is an important component for transferring string vibrations. The quality and thickness of the gum and the shape of the key parts have direct influence on the tone.

Two symmetrical crown angles are decorated on two sides of the dragon gum, and the same material as the dragon gum is generally used. The crown angle does not participate in the transmission of vibrations in principle, but only has an aesthetic effect.

The Chenglu is named Chenglu, wherein a hardwood strip parallel to the Yushan and made of the same material is inlaid between the Yushan and the forehead of the musical instrument. Seven string holes are arranged on the reception surface and used for penetrating through the pile buttons connected with the strings. The mountain is enabled to erect strings like a mountain, after the strings are connected with the pile buckles through the fly heads, the pile buckles vertically downwards along the mountain like flowing water, penetrate through the piano body through string eyes and are connected to the piano tuning fork on the bottom plate and the tuning fork pool plate. Therefore, ancient people called dew reception, which is about to receive dew.

In the traditional process for manufacturing the seven-stringed plucked instrument, the dragon gum, the two crown corners and the hulu are all independent parts and are independently manufactured and then installed on a panel of the seven-stringed plucked instrument. The traditional process has the problems of low production efficiency and high manufacturing cost.

Detailed Description

In the following description, numerous technical details are set forth in order to provide a better understanding of the present application. However, it will be understood by those of ordinary skill in the art that the claimed embodiments may be practiced without these specific details and with various changes and modifications based on the following embodiments.

To make the objects, technical solutions and advantages of the present application more clear, embodiments of the present application will be described in further detail below with reference to the accompanying drawings.

In one embodiment, the composite panel of a guqin as shown in fig. 1 comprises: a wood panel 2 and a carbon fiber composite shell 1; wherein,

the case 1 covers the upper surface and the side surfaces of both long sides of the wood panel 2 (the side surfaces of the long sides refer to the side surfaces seen in fig. 5);

the case 1 is integrally formed in a stamping mode, the case 1 comprises a dragon gum 12 and two crown corners 11 (shown in fig. 2) which are located on the upper surface of a tail of the guqin, a hulu 9 (shown in fig. 3) which is located on the upper surface of a head of the guqin and is adjacent to a Yueshan 8 of the guqin, and cross-board protecting side wings 10 which are located on two side surfaces of the head of the guqin. The shell 1 also has an opening 14 at the position of the mountain so as to be convenient for installing the mountain 8.

The housing 1 is fixed to the wooden panel 2 by gluing or other fixing means.

In the traditional process, the dragon gum, the crown angle and the dew are all independent parts which are independently manufactured and then are installed on the wood panel. This application embodiment is through with gum, two crown angles, dew bearing and front guard tuner flank integrated into one piece on carbon-fibre composite's casing with the punching press mode, fix the casing again to wooden panel on, the independent accessory quantity of guqin that has significantly reduced has improved production efficiency, has reduced the time of assembly, has reduced manufacturing cost.

In one embodiment, the upper surface of the wood panel 2 further comprises raised structures 13 matching the two crown corners 11 of the shell 1 at the guqin tail.

In one embodiment, the carbon fiber composite has a density of 1.3 to 1.5 grams per cubic centimeter.

In one embodiment, fig. 4 and 5 illustrate the mating relationship of the composite face plate and other major components on the body. The body also comprises a wood bottom plate 3 and a carbon fiber composite bottom plate 4. The carbon fiber composite material bottom plate 4 is fixed on the lower surface of the wood bottom plate 3. The wood panel 2 and the wood bottom plate 3 are matched to form a hollow piano cavity. And the goose feet 5, the music instrument tuner 6 and other parts are also assembled below the carbon fiber composite material bottom plate 4.

In one embodiment, the upper side of the guide peg 7 of the guqin head is fixed to the lower surface of the wood panel 2, and the side surface of the guide peg 7 is fixed to a guide peg side wing 10 of the shell 1.

Fig. 6 shows three views of the guide peg 7. The lower side in fig. 6 is a view from the headstock toward the tail, the upper left side in fig. 6 is a view from the bottom of the guqin toward the upper direction, and the right side in fig. 6 is a view from the side of the guqin along the long side.

The tuner board 7 includes two leg portions 15 and a saddle portion 16 connecting the two leg portions 15; the saddle 16 is in a flat plate shape, the thickness of the saddle 16 is the same as that of the inner bottom plate 3, one end of the outer bottom plate 4 close to the headstock is pressed on the saddle 16, and thus the cross-board 7 is fixed between the outer bottom plate 4 and the inner panel 2; the side surface of the guide peg 7 is fixed to the guide peg side wing 10 of the outer panel 1. The side wings protect the wooden guide peg from the outer side surface, and the hardness of the carbon fiber composite material is greatly higher than that of wood of the guide peg, so that the guide peg can be effectively protected from being damaged from the outer side surface.

The guide peg in the embodiment is different from the traditional guide peg, the guide peg of the traditional guqin is only two separated feet, and the two feet are connected through a saddle part to form a whole, so that the guide peg can be machined by a numerical control machine tool at one time, and the number of parts is reduced. In addition, the saddle part can be pressed by the carbon fiber composite material bottom plate 4 (see fig. 4 and 5), so that the fixing of the tuner board is firmer.
