Abstract

A musical instrument is realized by adding structures such as a ceiling, a ceiling cavity, a flowing sound and a wife sink cavity on a hacking panel of the existing musical instrument: a new variety is added to the guqin, and the guqin can produce harmony and stereo sound effect when stroking. Due to the fact that the structures such as the zenith and the Fu pond are additionally arranged, the functional effect of resisting the deformation of the organ is improved, and the problem that the organ is easy to deform in thousand years is solved.

Description

Musical instrument

One, the technical field

The invention relates to a scoring process for a Guqin.

Second, background Art

For thousands of years, the whole existence and continuous development of the ancient musical instrument art, people have integrated the philosophy of the ancient musical instrument to a very high position, become a teacher device capable of concentrating the Chinese traditional culture, and the gorgeous artistic effects of various styles and paints become a collector with high ornamental value and also become the most outstanding practical representative device for reflecting the Chinese traditional national musical instrument.

The traditional ancient musical instrument scoring technology is that a forming base is made of wood, a flax cloth is wrapped outside, and then paint ash and surface paint are painted. The main material of the paint ash is natural resin paint, also called lacquer or Chinese lacquer. The curing requirement of the lacquer can simultaneously meet the requirements of about 25 ℃ and over 80% of humidity, so that the optimal use requirement effect of the lacquer can be ensured. While both the paint ash and the surface paint need to be accumulated through several or even tens of passes to achieve the desired thickness. Water grinding finishing is needed between each layer of coating, so that the wood is repeatedly recycled in dry and wet environments, deformation is inevitable, and the defects of waist collapse, back arch and the like of a musical instrument caused by the deformation exist, so that the ancient difficult problem to be solved by a scoring operator is solved.

Third, the invention

In view of the above-mentioned drawbacks and deficiencies of the prior art, the present invention provides a new solution: the most important is to solve the defects of waist collapse, arch back and the like of the organ caused by wood deformation, provide the function of resisting longitudinal bending similar to an arch cylinder, improve the function effect of resisting the deformation of the organ and solve the problem of easy deformation of the organ in thousand years.

Description of the drawings

The attached drawing is a cross-sectional schematic diagram of any position (pool and marsh is not shown) between the second badge and the third badge of the musical instrument.

Fifth, detailed description of the invention

The invention is detailed below with reference to the accompanying drawings, and the musical instrument scoring method is characterized in that in a common musical instrument scoring process, on a prepared panel 1, pits with the depth of about 0.7cm to 1cm are dug according to the measured size to form a husband pool 4, one or more than several spacing struts 4 with the width of about 0.5cm can be arranged between the lengthwise lengths of the husband pool, and a plurality of day ventilation holes 4 or day ventilation grooves 4 are arranged on the spacing struts, wherein the required length of any one of the two emblems to the thirteen emblems is measured, the width of each pit is below one chord and seven chords, and the side opening ranges from 1cm to 1.5 cm. When the separation support is arranged, 2 separation basins are formed by arranging one

separation support

4, and 3 separation supports are formed by arranging 2 separation support basins. The upper through hole or slot can open the adjacent husband pool (the upper cavity 4). The periphery of the Hufu cell and the spacers (if provided) are provided with a stop 7 whose depth corresponds to the thickness of the zenith 5 prepared as follows, and the Hufu cell can be made without a sound flowing hole structure. A plurality of flow sound holes 6 are drilled in the prepared groove belly 3 on the fabric, the holes 6 are communicated with the husband pool 4, the upper edge and the lower edge of each flow sound hole 6 are rounded, the upper edge of each rounded hole 6 is connected with the upper end of the upper end, and the lower edge of each rounded hole is connected with the lower end of the upper end. The husband's basin at this time forms the upper chamber 4, and the abdomen 3 forms the wife's (floor) chamber 3. According to the geometric dimension of the husband pool 4, a plurality of sheets are taken by using wood or bamboo sheets, the wood or bamboo sheets are stuck and spliced in the husband pool 4 according to the positive and negative treatment plates by using paint ash in a staggered or staggered manner, the paint ash is solidified and then is repaired into the zenith 5 corresponding to the panel 1 in an arc shape, and the number of the zenith corresponds to the number of the husband pools one by one. When the top of the spacer support corresponds to the depth of the seam allowance, the number of the top of the spacer support and the number of the husband pool can also be one-to-two or one-to-three. The zenith thickness is related to the depth of the fuguchi by: the top thick pool is shallow, the top thin pool is deep, and the top thick pool is equal in depth. The materials for the ceiling 5 can be arranged in a staggered manner from wood to bamboo by half round metal pipe from bamboo to wood according to the requirement.

Of course, the material of the zenith 5 can also be chosen from metal plates, such as steel, copper alloy, aluminium-magnesium alloy or corrugated plates thereof, the geometry of which corresponds to the arc of the pool 4 and the panel 1. One or more of linen, silk cloth or carbon fiber cloth can be selected, the lamination is pasted by lacquer to be in the required thickness and arc shape, and the lamination is cut and embedded in the husband pool 4 to form the ceiling 5. The repair zenith 5 and the surface of the piano are straight and smooth (when corrugated plates are adopted, the repair zenith is embedded into the tank, and the upper groove is filled with paint ash). The prepared bottom plate 2 is bonded with the fabric (the bottom plate 2 can be not provided, for example, when a bottomless piano is hacked), and the hemp cloth can be wrapped after curing, and painting dust is painted until the piano is finished by conventional operation.

With reference to one of the above musical instrument preparations, the fudge geometry may also be such that grooves are formed in the string, the length of which may be staggered, for example, 80cm for a 4-chord groove, 60cm for a 2-chord 6-chord groove, 30cm for a 3-chord 5-chord groove, 40cm for a 1-chord 7-chord groove, and the width and depth of the groove may be about 1cm by 1.2 cm. Deep grooves with equal length can be opened only in the chords of 2, 4 and 6 to form the husband cell 4. And (3) taking a batten, a metal round pipe or a square pipe or U, A type section material or a glass pipe with corresponding size as a ceiling 5 material, inlaying the ceiling 5 material into the groove of the corresponding pool, and flatly filling the gap. At the two ends of the groove and any required position, a plurality of sound flowing holes 6 are pre-drilled, and the upper edge and the lower edge of each hole are rounded. The upper edge of the round hole 6 is Tiantong, and the lower edge is wife. The husband pool and the Tiantong form a sky cavity, and the wife pool form a ground cavity (the upper edge and the lower edge of the hole 6 are rounded, so that the sound waves collected in the husband pool 4 can gradually converge through the flow sound hole 6, and gradually expand to converge with the sound waves in the groove belly 3 to generate harmony or stereo sound effect).

The musical instrument is realized by adding structures such as a ceiling, a ceiling cavity, a flowing sound, a wife sink cavity and the like on a panel during scoring of the existing ancient musical instrument. A new variety is added in the aspect of scoring and using the ancient musical instrument, and the new variety can produce the effect of harmony or stereophonic sense when playing the bullet. The preparation of its husband pond weakens the inherent internal stress of guqin ware panel in fact, and the preparation of its zenith adopts just, anti reason board to join in marriage with its circular arc structural morphology that must deal with in the musical instrument panel of straying, can produce the anti longitudinal bending effect of similar arch, has improved the functional effect of resisting musical instrument deformation, has solved the changeable thousand guy difficult problems of musical instrument.
