Abstract

A musical instrument is realized by adding zenith, zenith cavity, flowing sound, wife cavity and other structures on the existing Gu Qinqin scoring panel: a new variety is added for the ancient musical instrument, and the ancient musical instrument can generate chord and stereo sound effects when being stroked. Because the structures such as zenithal, fuchi and the like are added for preparation, the functional effect of resisting the deformation of the organ is improved, and the thousand-old problem that the organ is easy to deform is solved.

Description

Musical instrument

1. Technical field

The invention relates to a scoring process of an ancient organ.

2. Background art

For thousands of years, the integral existence and continuous development of the ancient musical instrument art have endowed the integration of the philosophy art with extremely high position, and the ancient musical instrument becomes a teaching device capable of concentrating the traditional Chinese culture, has various styles and colorful artistic effects, becomes a collector with great ornamental value, and is also a practical representative which shows the most outstanding traditional national musical instrument.

The traditional Guqin scoring process is to make a forming tire with timber, wrap flax cloth outside and then include painting ash and surface paint. The main material of the paint ash is natural resin paint, also called lacquer or Chinese lacquer. The curing of the lacquer needs to meet the requirements of the temperature of about 25 ℃ and the humidity of more than 80 percent at the same time, so that the optimal use requirement effect of the lacquer can be ensured. While the paint ash and the surface paint are accumulated through several or even tens of processes to reach the required thickness. The coating layers are required to be polished by a water mill, so that the wood is repeatedly rotated in dry and wet environments, deformation is difficult to occur, and the defects of waist collapse, back arches and the like of the organ caused by deformation exist, so that the wood is a thousand-old problem to be solved by a scoring organ operator.

3. Summary of the invention

In view of the above-mentioned drawbacks and deficiencies of the prior art, it is an object of the present invention to provide a new solution: the key point is to solve the defects of waist collapse, back arch and the like of the organ caused by wood deformation, provide a longitudinal bending resistant effect similar to arch barrel, improve the functional effect of resisting the organ deformation, and solve the thousand-old difficult problem of easy deformation of the organ.

4. Description of the drawings

The drawing is a schematic cross-sectional view of any position (pond biogas is not shown) from two emblems to thirteen emblems of the organ.

5. Detailed description of the preferred embodiments

In the process of scoring a conventional organ, a cutting face 1 is provided with a groove 4 with a depth of about 0.7cm to 1cm, a spacer 4 with a width of about 0.5cm and a plurality of sound through holes 4 or sound through grooves 4 on the spacer, wherein the width is measured at any position from two to thirteen cutting marks according to the required length and the width is measured at 1cm to 1.5cm below one chord and seven chords, and the grooves are dug according to the measured size to form the grooves 4. When the spacer is arranged, one pool 4 is arranged to form 2 pools, and 2 pools are arranged to form 3 pools. The space through holes or grooves can open the adjacent cells (space cavity 4). On the periphery of the pool and on the spacer (if set), there are made seam allowance 7 whose depth corresponds to the thickness of zenith 5, at this time, the zenith is prepared as follows, and it can be used as a musical instrument without a sound hole structure. In the prepared groove web 3 on the fabric, a plurality of flow sound holes 6 are drilled, the holes 6 are communicated with the sink 4, the upper and lower edges of the flow sound holes 6 are rounded, the upper edge of the rounded holes 6 is Tiantong, and the lower edge is wife. The pool forms a space 4 and the abdomen 3 forms a wife (earth) cavity 3. The geometry of the Schiff base 4 is obtained by taking a plurality of sheets of wood or bamboo, and the sheets are spliced in the Schiff base 4 by using the spread or staggered sticking of paint ash according to the positive and negative arrangement, and the paint ash is solidified and then repaired into zenith 5 corresponding to the arc shape of the panel 1, and the zenith number corresponds to the number of the Schiff base one by one. When the zenith and the spigot depth are corresponding to each other, the zenith number and the fuchi number can be one-to-two or one-to-three. The zenith thickness is related to the depth of the pool: shallow top thick pool, top Bao Chishen and deep top thick pool. The materials are customized according to the requirements (the materials for the zenith 5 can also be arranged according to the staggered arrangement of one wood to one bamboo to one half round metal pipe to one bamboo to one wood).

Of course, the zenith 5 may also be made of metal plates, such as steel, copper alloy, aluminum magnesium alloy or corrugated plates thereof, the geometry of which corresponds to the arc of the cell 4 and the panel 1. One or more of linen, silk cloth or carbon fiber cloth can be selected, the lamination is made into a required thickness and arc shape by using lacquer paste, and the required thickness and arc shape are cut and embedded in the pool 4 to form the zenith 5. Repairing zenith 5 and the piano face are flat, straight and smooth, and when corrugated plates are adopted, the corrugated plates are embedded into a pool, and paint ash is used for filling the upper groove). The finished base plate 2 is bonded with the face material (the base plate 2 can be omitted, for example, when a base-less organ is made by scoring), and the base plate is cured to be wrapped with linen, and the conventional operations such as painting ash and the like are finished by an organ machine.

With reference to the preparation of the musical instrument, the geometry of the pool can also prepare grooves under strings, and the grooves can be staggered, for example, the groove lengths under strings 4 are 80cm, the groove lengths under strings 2 are 6 are 60cm, the groove lengths under strings 3 are 5 are 30cm, the groove lengths under strings 1 are 7 are 40cm, and the groove widths and depths are 1cm by 1.2 cm. Deep grooves with equal length can be opened only at the strings of 2, 4 and 6 to form the pool 4. Taking wood strips, round or square tubes or U, A-section or glass tubes with corresponding sizes as zenith 5 materials, embedding the zenith 5 materials in corresponding grooves Chi Caogou, and filling gaps horizontally. At both ends of the groove and at any required position, a plurality of flow sound holes 6 are pre-drilled, and the upper and lower edges of the holes are rounded. The upper edge of the round-smeared hole 6 is Tiantong, and the lower edge is wife. The pool and the tencel form a space cavity, a wife gloss and a wife converging cavity to form a ground cavity, (the upper and lower edges of the hole 6 are rounded so as to enable sound waves collected in the pool 4 to gradually pass through the sound flowing hole 6 and gradually expand to generate a chord or stereo sound effect after being converged with sound waves of the belly 3).

In summary, the organ is realized by adding zenith, zenith cavity, flowing sound, wife cavity and other structures on the panel of the existing ancient organ scoring. A new variety is added in the manufacture and use of the guqin scoring, and the guqin scoring can generate a chord or stereo sense effect when playing. The preparation of the fuchi weakens the inherent internal stress of the panel of the organ, the zenithal preparation adopts staggered preparation of a positive plate, a negative plate and the like, and the circular arc structure form of the panel of the organ should be dealt with, thereby generating the longitudinal bending resistance effect similar to arch barrel, improving the functional effect of resisting the deformation of the organ and solving the thousand-old problem of the variability of the organ.
