Embodiment Construction

[0026] The present invention will be further elaborated and illustrated below in conjunction with the accompanying drawings and specific embodiments. The technical features of the various implementations in the present invention can be combined accordingly on the premise that there is no conflict with each other.

[0027] In this example, if figure 1 A new musical instrument based on the reverse flow principle of the Tesla valve is shown, which is made of aluminum alloy as the main material. The structure of each part is described in detail below.

[0028] Playing pipe 16 is the pipe body that is played for the user, and its main part outer diameter is 28mm, and internal diameter is 24mm, and the blowing mouth 1 cross-section of wherein end is U-shaped. And in order to facilitate the generation of edge sound, draft 30 degrees at the circular arc place of this blowing mouth 1.

[0029] The cavity of the Tesla valve is a deformation of the classic model Tesla valve. It has th...

Abstract

The invention discloses a novel wind instrument, the structure of which comprises a blowing pipe, a Tesla valve sound changing cavity and a central main pipe; the main pipe is provided with eight sound-pressing holes and two sound-correcting holes, and the end of the wind playing pipe of the wind instrument is connected to the pipe through a threaded joint. The voicing cavity of the Tesla valve is connected, and the phonic cavity of the Tesla valve is connected with the central main pipe by welding. The cavity of the Tesla valve has the ability to change the internal flow field. Based on the original sound of the ordinary flute, the sound of air flow can be generated, which can effectively change the tone of Xiao Yuan. The invention proposes a novel wind instrument with novel structure and unique timbre, which can be widely popularized and applied.

Description

technical field [0001] The invention relates to a novel musical instrument based on the reverse flow principle of a Tesla valve, in particular to a novel musical instrument with multiple tubes vibrating and sounding together and having an effect similar to that of "Hoo Mai". Background technique [0002] Xiao is a traditional musical instrument in China, and many people are still learning Xiao instruments today. But in the process of learning, because it is a mouth-to-mouthpiece instrument, due to hygiene problems, it cannot be shared by many people. There are many published invention patents that have modified its structure: such as CN201521018094.1 a metal hole flute, CN201220449846.X a new type of short flute, CN201320302513.9 a pocket flute, CN201320302505.4 a pocket gift flute, these All the utility models have retained the original structure of Xiao, but the size and material have been modified. The solution to the sanitation problem is simply to make it easy to clea...
