Description

Technical Field

[0001] The invention relates to the technical field of musical instrument manufacturing, in particular to a construction method of a double-layer hollowable sound tube of a flute or Xiao-type musical instrument. Background Art

[0002] As a traditional folk musical instrument, flute and Xiao have a long history in my country. Traditional flute and Xiao sound pipes are mostly single-layer structures, which limits the possibility of further improving the timbre, volume and appearance of the instrument. Various improvement schemes have appeared in the existing technology, but there are still certain limitations. Therefore, in order to improve the timbre, volume and appearance of flute and Xiao, it is necessary to study a new method for constructing flute and Xiao sound pipes, combined with the needs of digital production and manufacturing, to improve their sound quality and appearance. Summary of the invention

[0003] The present invention provides a method for constructing a double-layer hollowable sound tube of a flute or Xiao musical instrument, the method comprising the following steps: 1. Prepare an inner tube, which is the main sound tube of a flute or other musical instrument, and has a mouthpiece and at least one sound hole; the number and position of the sound holes are determined according to the musical requirements of the musical instrument.

[0004] 2. Prepare an outer tube, which is a hollow auxiliary sound tube. Its inner diameter is larger than the outer diameter of the inner tube. A certain space is reserved between the inner tube and the outer tube so that the outer tube can be sleeved on the outside of the inner tube and prevent noise from being generated due to vibration of the inner tube.

[0005] 3. Determine the blowing hole, and form a hollow portion on the outer tube corresponding to the position of the blowing hole of the inner tube, so that air can be blown from the outer tube into the inner tube; 4. Determine the sound hole, and form a hollow portion on the outer tube corresponding to the position of the sound hole of the inner tube, so that the sound can be transmitted from the sound hole of the inner tube through the hollow portion of the outer tube.

[0006] 5. Hollow pattern: the outer tube can combine various patterns and sound resonance effects to form a hollow pattern or texture shape to enhance the beauty of the instrument and the expression of the tone.

[0007] 6. Set up a buffer zone for the sound hole of the outer tube, leaving a certain non-hollowed area around the sound hole of the outer tube so as not to interfere with the blowing, film sticking, and playing feel. At the same time, reserve enough space for fixing the joint of the inner tube and the outer tube.

[0008] 7. Establish a connection part to connect the joint of the inner tube and the outer tube so that the inner tube and the outer tube are fixed as one; (71) a fixed connection part, connecting the inner tube and the outer tube through the corresponding sound hole ring wall of the inner tube and the outer tube; (72) a flexible connection part, the connection part between the tail of the inner tube and the outer tube avoids the hollow part of the outer tube. The inner and outer layers of the sound tube are fixed together by one-piece forming or threaded connection, bonding, welding, snap connection and elastic connection to form a double-layer sound tube structure; except for one-piece forming, other connection methods need to be equipped with seals at the connection to prevent air leakage.

[0009] The present invention has the following advantages: 1. The double-layer sound tube structure provides more possibilities for adjusting the timbre and volume of flute and other instruments; 2. Hollow design can reduce the weight of the instrument, improve the playing feel, and enhance the visual effect of the instrument's appearance; 3. It can be digitally modeled and integrated for manufacturing, with distinctive features, batch production, and easy promotion.

[0013] The present invention is described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0014] Embodiment 1: Bamboo is selected as the material of the inner layer sound tube, and hardwood is selected as the material of the outer layer sound tube. First, the bamboo and hardwood are processed into a hollow tubular structure, the inner diameter of the inner layer bamboo tube is 10 mm, and the inner diameter of the outer layer hardwood tube is 13 mm. Then, a mouthpiece is set at one end of the bamboo tube, and a mouthpiece hole is opened at the corresponding position of the hardwood tube. Next, 6 sound holes are opened at the corresponding positions of the bamboo tube and the hardwood tube. The bamboo tube and the hardwood tube are bonded together to form a double-layer sound tube structure. Finally, the outer surface of the outer layer sound tube is hollowed out to form a traditional Chinese pattern.

[0015] Embodiment 2: Resin material is selected as the material of the inner sound tube, and metal material is selected as the material of the outer sound tube. First, the inner and outer sound tubes are digitally modeled through computer-aided design. The inner diameter of the inner resin tube is 13mm, a mouthpiece is set at one end of the inner tube, 7 sound holes are opened at the corresponding position on the front, and one sound hole is set at the corresponding position on the back; the inner diameter of the outer metal tube is 16mm, a mouthpiece and a sound hole are set at the corresponding position of the inner tube; and an interface is reserved at the junction of the inner tube and the outer tube; then, they are printed and formed separately through 3D printing; then, the resin tube and the metal tube are bonded together to form a double-layer sound tube structure. Finally, the outer surface of the double-layer sound tube is hollowed out to form a modern art pattern.

[0016] Summary: In summary, the present invention provides a method for constructing a double-layer hollow sound tube of a flute-like musical instrument, which has the advantages of digital modeling and integrated manufacturing, distinctive features, batch production, and easy promotion, and has high practical value and market prospects.
