Technical Field

The invention relates to the field of arris wind instruments, in particular to a vertical bamboo flute and a flute made of bamboos.

Background

The traditional flute and flute are national musical instruments made of other natural bamboo materials (hereinafter referred to as natural bamboo materials) except the bamboo materials of the square bamboo, and the quality of intonation and acoustics is required to be ensured like other musical instruments.

The intonation of the vertical bamboo flute and the flute is determined by two factors, one is subjective factor, namely processing technology and processing precision, the vertical bamboo flute and the flute can meet the requirements through the effort of a producer, and the other is objective factor, namely the geometric shape and the size of the bamboo wood. The manufactured vertical bamboo flute and the flute have intonation requirements due to the fact that geometric parameters such as the inner diameter and the outer diameter of the natural bamboo wood, the taper and the ovality of the bamboo tube are inconsistent, and the intonation of the manufactured vertical bamboo flute and the flute can be compensated to a certain extent through adjustment of a manufacturer, but the manufactured vertical bamboo flute and the flute are limited, and the intonation of a large number of vertical bamboo flute and flute products cannot meet the requirements. Also, some people use woods such as redwood, sandalwood to make vertical bamboo flute and flute, and solid woods are processed into wooden tubes, the geometric shapes and the sizes of the wooden tubes can be controlled, the tone can meet the requirements, but the material and the processing cost are very high, more importantly, the acoustic quality does not conform to the aesthetic quality of the traditional bamboo vertical bamboo flute and flute, so the wooden tubes cannot be popularized.

The acoustic quality of the flute and the flute is determined by the material of bamboo wood, namely the fiber density of a bamboo body and the wall thickness of a bamboo tube, the more compact the material of the bamboo wood is, the better the acoustic quality is, the thicker the wall thickness of the bamboo tube is, the better the acoustic quality is, the bamboo wood used for manufacturing the flute and the flute at present is thinner the bamboo wall of most bamboo woods, the flute and the flute products with good acoustic quality account for a very small proportion, the acoustic quality of most flute and flute products is poor, and the consistency of the acoustic quality is poor.

The natural bamboo wood has a plurality of varieties and can be used for making the bamboo flute and the flute with few varieties. There are mainly the following problems:

1. the existing natural bamboo material has defects

The bamboo material for manufacturing the vertical bamboo flute has the following requirements: the bamboo tube has the advantages of compact fiber, thick bamboo wall, certain conicity of the inner hole of the bamboo tube, perfect circle or certain ovality of the bamboo tube and the like, and most of natural bamboo materials cannot meet the requirements. The bamboo wood which can be used for making the vertical bamboo flute is few, mainly comprises: (1) the problem of the purple bamboo is that the bamboo wall is thin and the fiber is not compact enough; (2) mottled bamboo, the bamboo wall is not thick enough, the resource is very limited; (3) the bitter bamboo is mainly used for manufacturing bamboo flute due to long bamboo joints and thin walls, but the resource is limited, particularly the high-quality bitter bamboo material is scarce, and the bitter bamboo is easy to crack.

2. The existing natural bamboo wood has irregular size and shape and large discreteness

Because the diameter, the wall thickness, the geometric shape, the density degree of the material and the like of each natural bamboo material are different, after the bamboo flute and the flute are processed, the acoustic quality and the intonation of the bamboo flute and the flute are also different, namely the consistency of the acoustic quality and the intonation is poor, the manual debugging is needed, even if the manual debugging is needed, the high-quality bamboo flute and the flute which are processed are difficult to ensure, the finished product rate is low, and the superior product rate is lower.

3. Making vertical bamboo flute and long production period

The traditional bamboo wood has long drying time, generally, the bamboo flute and the flute can be made only in the shade drying time of more than four years, the acoustic quality is good in more than ten years, the excellent acoustic quality can be realized only in twenty to thirty years, and the production period is long.

4. Destruction of ecological resources

When bamboo of a flute and a flute is cut in a bamboo forest, the most elegant bamboo is selected to be cut, and after the most elegant bamboo is cut off, the bamboo does not grow bamboo shoots, so that excellent bamboo is fewer and fewer in the past, the cut has more harm to resources, vicious circle is formed, and actually, a lot of excellent bamboo resources are cut to be longer and cannot be better, so that the bamboo is commonly called to be cut.

The Chinese patent database relates to the related patents and patent application parts of bamboo flute and bamboo flute, which are as follows: the patent applications include hundreds of patent applications such as ' a wide-range new bamboo flute ' in CN201811045663.X ', a vertical-blowing bamboo flute ' in CN201810953581.9 ', a flute used as a music baton ' in CN201720723191.3 ', a process for producing a bamboo flute by using bamboo waste materials ' in CN201210296467.6 ' and an improved panpipe and a manufacturing method ' in CN201811097161.1 '. Until now, there is no related application part for bamboo in the genus of bamboo to make flute and flute.

Disclosure of Invention

The invention discloses application of bamboo in bamboo flute and flute, aiming at solving the problems of thin bamboo wall, insufficiently compact material, long production period, lack of high-quality resources, inherent inconsistency of natural bamboo and the like in the process of manufacturing the flute and the flute by using the conventional natural bamboo, and improving the quality and consistency of the flute and the flute.

The newly discovered bamboo in the square bamboo genus has the following characteristics:

first, the fiber material is dense

High adaptability to growing environment

The square bamboo has low requirement on the growth environment, is widely distributed, is produced in Jiangsu, Anhui, Zhejiang, Jiangxi, Fujian, Taiwan, Hunan, Guangxi, Yunnan, Guizhou, Sichuan, Chongqing and other places, and has very rich resources.

For a long time, because the new characteristics of the square bamboo are not discovered, the square bamboo is a bamboo for bamboo shoots and is widely applied to the bamboo shoot industry, in addition, the square bamboo has no special purpose, and old bamboos are generally felled and destroyed for more than five years, so that the growth of new bamboo shoots is facilitated. The characteristics of the new findings of the square bamboo are exactly the best materials for manufacturing the bamboo flute and the flute, particularly the old bamboo growing for more than five years, the characteristics of the new findings from the first to the third paragraphs are more fully possessed, the characteristics are the best materials for manufacturing the bamboo flute and the flute, the waste materials can be quickly changed into precious materials through popularization and use in bamboo musical instruments, and the use value and the economic value of the square bamboo are greatly improved.

The characteristics of the bamboo in the bamboo genus of the square bamboo are very suitable for manufacturing the vertical bamboo flute and the flute which have excellent acoustic quality and intonation, excellent quality and good consistency and are convenient for standardized production.

So far, the technical personnel in the field have not found that the bamboo flute and the flute can be made by the characteristics of the bamboo material of the genus bamboos, and the bamboo flute and the flute made by the bamboo material of the genus bamboos have the following technical effects:

(1) because the bamboo wall of the square bamboo is extremely thick and has enough machining allowance, the blank can be machined into a standard size, and then the blank is drilled by a numerical control machine, so that standardized design, standardized and mass production can be realized, and the product yield and quality consistency are high.

(2) Because the thickness of the bamboo wall of the existing natural bamboo is thin and the consistency is poor, the difference of the geometric size or the geometric shape is large, after the hole opening process, one hundred percent of trial blowing is needed one by one, manual tuning is needed, compensation and correction are carried out through hole digging, the yield and the consistency are very low, and the product cost is very high. When the bamboo in the bamboo genus of the square bamboo is used for manufacturing the flute and the flute, the manual tuning process can be saved, and the processing cost is greatly reduced.

(3) The bamboo wall of the square bamboo is extremely thick, and the density of bamboo fibers is high, so that the tone accuracy and the acoustic quality are fully guaranteed, and particularly in the aspect of tone accuracy, the problem which needs to be solved but is not solved in the field for a long time is solved, which is an important technical progress of national musical instruments.

(4) Protect the natural ecology

In the bamboo shoot industry, old bamboos growing for more than five years are cut off every year, the bamboo materials are the best materials for manufacturing the vertical bamboo flute and the flute, the vertical bamboo flute and the flute are manufactured by adopting bamboo materials of the square bamboos in a large quantity, the natural ecology is not damaged, the problem of lack of the materials of the vertical bamboo flute and the flute is solved, the technical progress and the national culture development of national musical instruments are promoted, the income of bamboo farmers is increased, and the economic development of agriculture and forestry is promoted.

(5) Rich resources and low cost

The square bamboo has low requirement on the growth environment, wide distribution and very rich resources. The cost for producing the flute and the flute by using the bamboo material of the square bamboo is far lower than that of the existing natural bamboo material.
