Abstract
Description
Technical Field
[0001] The invention relates to the technical field of flute preparation, and in particular to a bamboo-wrapped wood flute with a bamboo tube on the outside and a rosewood tube embedded inside and a preparation process thereof. Background Art
[0002] Traditional flutes are made of bamboo tubes. Bamboo flutes have the advantages of loud sound and clear and pleasant tone. When processing bamboo flutes, it is not only necessary to select bamboo poles with the required outer diameter, but also to strictly select high-quality bamboo poles without cracks or damage. Therefore, it is not easy to choose high-quality bamboo. There are multiple sound holes on the bamboo tube. Under the same pitch, because the structural dimensions of each bamboo are different, if perfect pitch is required, the inner bore of the bamboo must be polished. However, after the inner bore of the bamboo is polished to a certain degree, although the pitch of the bamboo flute meets the requirements, the tone of the flute has changed. Therefore, it is difficult to have both pitch and tone for flutes made of bamboo tubes. In addition, many flutes will produce cracks because the bamboo itself will lose water during the storage process, causing the flute to leak sound and inaccurate pronunciation.
[0003] In the prior art, there are some solutions that use wood or plastic to prepare flutes, but the texture of the manufactured flutes is completely different from that of traditional bamboo flutes. For example, patent announcement number CN2783479Y discloses a wooden flute, the flute body is made of wooden material as a whole, and the wood is imported high-quality and high-grade wooden material, such as precious sandalwood wood. The preparation cost is very high, and its texture is completely different from that of the bamboo flute.
[0004] Some flutes in the prior art are made of composite materials. For example, the patent with the announcement number CN 204480649 discloses a flute that can play rhymes. The outer layer of the flute tube is made of wood, and the inner layer of the flute tube is made of bamboo. The outer layer of the wood tube is sleeved on the outer side of the inner layer of the bamboo tube and bonded into an integrated structure by gluing. The purpose of designing this flute is to protect the bamboo tube, prevent the bamboo tube from cracking, and extend the service life of the flute, but it cannot solve the problem of the difficulty in achieving both timbre and pitch in bamboo flutes.

[0013] In the above scheme, the difference in inner diameter between the head and the tail of the tapered hole is 0.5 mm to 2.5 mm.
[0014] In the above scheme, the length of the tube body is 40-75cm, the outer diameter of the outer tube is 16-25mm, the inner diameter of the outer tube is 15-23mm, the outer diameter of the inner tube is the same as the inner diameter of the outer tube, the inner diameter at the head of the inner tube is 14-20mm, and the inner diameter at the tail of the inner tube is 12-18mm.
[0015] In the above scheme, the head of the tube body is sleeved with a flute head, the tube body is inlaid with ox horns and copper sleeves, the outer wall of the tube body is coated with shellac and paint, and the tube body is provided with binding wires and engravings.
[0016] The present invention has positive effects: 1) The bamboo-wrapped wood flute and its preparation process of the present invention, the tube body includes an outer tube and an inner tube, the outer tube is a bamboo tube, and the inner tube is a wooden tube made of rosewood. Because through testing, the pronunciation of the rosewood inner tube is basically the same as that of the bamboo tube, so the inner tube is made of rosewood to ensure the timbre of the flute, and the processing of the inner bore can also ensure its pitch, so the bamboo-wrapped wood flute made in this way can have both high-quality timbre and pitch, and improve the pronunciation quality of the flute. 2) The bamboo-wrapped wood flute and its preparation process of the present invention use the rosewood inner tube as the pronunciation part, so when selecting bamboo, there is no need to consider the influence of bamboo on the pronunciation of the flute, and some bamboo tubes with small cracks or defects can be selected, which can reduce the selection criteria of bamboo and make the selection range of bamboo wider. 3) The bamboo-wrapped wood flute and its preparation process of the present invention have greatly reduced costs compared with wooden flutes made of precious wood alone in the prior art. In addition, the wooden tube is not easily worn during use, so the bamboo-wrapped wood flute can be used for a long time without deterioration in sound quality, which can greatly extend its service life. At the same time, because the bamboo-wrapped wood flute can still retain the texture and feel of the bamboo flute on the outside, it feels exactly the same as the bamboo flute when played, thereby improving the user experience.
