Problems solved by technology

[0009] The present invention aims at the problem of poor sound changing effect of the existing flute, and provides a new type of sound changing flute. By improving the structure of the blow hole of the flute, the sound source of the flute, that is, the air layer existing on the blow hole and The adjustment of the air column in the official cavity improves the player's grasp of the speed of the airflow, and significantly improves the ability to control the pronunciation of the flute and the ability to control the change of the flute.

Embodiment 1

[0029] An altered flute, including a flute tube and keys, wherein the flute tube includes a flute head, a flute body and a flute tail, and the flute tube part is provided with a blow hole, a sound hole and a flute plug, and the flute tube is made of aluminum metal. Diameter D is 1.5cm, and the length L=30D of flute tube, take the central line of blow hole as reference, the film material of nanotube coating on the inner surface of the flute part of front and rear 3cm, the thickness of film is 300nm.

[0030] The coating process is as follows: disperse 100 mg of commercially available carbon nanotubes in 30 g of deionized water, add 200 mg of dispersant sodium lauryl sulfate, and ultrasonically disperse; place the dispersed carbon nanotubes in the top loading liquid of the spray gun In the cup, adjust the pressure of the nitrogen cylinder and the outlet of the spray gun, and use nitrogen to send the liquid, so that the carbon nanotube dispersion becomes a mist through the spray g...

Embodiment 2

[0033]An altered flute, including a flute tube and keys, wherein the flute tube includes a flute head, a flute body and a flute tail. Diameter D is 2cm, and the length L=33D of flute tube, take the centerline of blow hole as reference, the film material of nanotube coating on the inner surface of the flute part of front and rear 3cm, the thickness of film is 200nm.

[0034] The coating process is: disperse commercially available titanium dioxide nanotubes in 100 mg in 30 g of deionized water, add 200 mg of dispersant sodium lauryl sulfate, and ultrasonically disperse; place the dispersed carbon nanotubes in the top loading liquid of the spray gun In the cup, adjust the pressure of the nitrogen cylinder and the outlet of the spray gun, and use nitrogen to send the liquid, so that the carbon nanotube dispersion becomes a mist through the spray gun for spraying. During the spraying process, the temperature of the pipe is maintained at about 100 °C.

[0035] When the obtained flut...

Embodiment 3

[0037] An altered flute, including a flute tube and keys, wherein the flute tube includes a flute head, a flute body and a flute tail. The diameter D is 2cm, and the length L of the flute tube is 33D. Taking the center line of the blowing hole as the reference, the inner surface of the front and back 3cm flute tube part is coated with a thin film material of nanotubes. The thickness of the film is 200nm. The coating process uses electroplating coated.

[0038] When the obtained flute is played, it is easy to control the number of harmonics when playing, and to realize the change of timbre.

Abstract

The invention relates to a tone-variable flute comprising a flute pipe and keys. The flute pipe consists of a flute head, a flute body and a flute tail; a blowing hole, a sound hole, and a flute plugare arranged at the flute pipe. The flute pipe is made of a metal material, has the diameter D of 1.5 to 2.5cm, and has the length L being larger than or equal to 30D and being less than or equal to 35D. The flute is characterized in that the central line of the blowing hole is used as the standard; and the inner surfaces of the first 3-cm flute pipe part and the last 3-cm flute pipe part are coated with nano-tube film materials, wherein the film thickness is 50 to 300nm. When the flute is used for playing, the tone is mellow, imple, and vigorous and the sound is clear and pleasing.

Description

technical field [0001] The invention belongs to the field of musical instruments, and in particular relates to a pitch-changing flute. Background technique [0002] The musical instrument called "Flute" in Chinese and "Flute" in foreign languages ​​has a beautiful sound and is good at expressing people's musical emotions towards natural scenery. It is a Western woodwind instrument. The flute is the main high-pitched melody instrument in modern orchestral music and chamber music, and belongs to woodwind music. The flute is an important component of the orchestra, wind band and woodwind ensemble. It is also a solo instrument with gorgeous timbre and flexible skills. It can play slow, broad, lyrical melodies or cadenzas with high skills. [0003] There are two types of flute, woodwind and metal pipe. The appearance of the two is not much different, and the playing skills are the same. The appearance is a long cylindrical tube with several sound holes. Early flutes were made ...
