Abstract

The invention discloses a novel wind instrument. The novel wind instrument structurally comprises a playing pipe, a Tesla valve tone change cavity and a center main pipe; eight sound pressing holes and two tuning holes are formed in the main pipe; the tail end of the playing pipe of the wind instrument is connected with the Tesla valve tone change cavity through a threaded joint; and the Tesla valve tone change cavity is connected with the center main pipe through welding. The Tesla valve tone change cavity has the capability of changing an internal flow field, generates an airflow sound on the basis of an original ordinary vertical bamboo flute sound, and can effectively change the original tone of a vertical bamboo flute. The novel wind instrument is novel in structure and unique in tone, and 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...

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 external diameter is 28mm, and internal diameter is 24mm, and the blowing mouth cross section of wherein end is U-shaped. And in order to facilitate the generation of edge sound, the arc of the blowing port is drafted at 30 degrees.

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