Problems solved by technology

The airflow blown from the mouthpiece into the resonance box revolves in the resonance box and then is discharged from the air outlet. At the same time, the swirling airflow pushes the ball to oscillate back and forth in the resonance box, so that the whistle can produce a broken sound effect with a fixed pitch, but its Can't play different pitches
In the traditional edge wind instrument, the air flow passes through the edge structure to excite the air column of the sound pipe, and the fingerholes of different lengths play different pitches, but cannot play the crunch effect

Embodiment 1

[0025] like figure 1 , figure 2 and image 3 Shown, a kind of crappie wind instrument, comprises mouthpiece 1, resonance box 2 and sound tube 3, resonance box 2 is cylindrical, and there is an elastic ball 4 in resonance box 2, and elastic ball is cork ball, and diameter is 0.6- 0.9cm. The mouthpiece 1 is located at the front end of the resonance box 2, the sound tube 3 is located at the rear end of the resonance box 2, the upper part of the resonance box 2 is near the sound tube and has an air outlet 5, and the upper end of the front part of the sound tube 3 and the air outlet 5 have a first sounding edge Edge 7 and the second sounding edge 8, the front ends of the two sounding edges are wedge-shaped, the first sounding edge 7 and the second sounding edge 8 are stacked up and down, and the first sounding edge 7 and the second sounding edge The front end of the edge 7 is staggered back and forth by 1-1.5 mm in the horizontal direction. There are 7 finger holes 6 on the so...

Embodiment 2

[0028] This embodiment differs from Embodiment 1 in that, as Figure 4 As shown, the side of the resonance box 2 is a detachable cover 11 to facilitate the replacement of elastic balls 4 of different sizes. The outer periphery of the cover 11 has an annular flange 12 facing the resonance box 2 , and when the cover 11 is buckled on the resonance box 2 , the annular flange 12 is sleeved on the resonance box 2 .

[0029] like Figure 5 As shown, the sound tube 3 also has a finger collar, and there are two finger collars, the two finger collars are respectively a thumb collar 9 and a little finger collar 10, the thumb collar 9 is located at the lower part of the front end of the sound tube 2, and the little finger collar The ring 10 is located at the rear end of the sound tube. In order to adjust the angle of the little finger collar 10, an annular base can also be fixed at the rear end of the sound tube 3. The annular base has an annular chute, and the lower part of the little ...

Abstract

The invention relates to a broken-tone wind instrument, comprising a blowing mouth, a resonance box and a sound pipe. The resonance box is cylindrical, and a small elastic ball is arranged in the resonance box, the blowing mouth is located at the front end of the resonance box, the sound pipe is located at the rear end of the resonance box, the upper part of the resonance box is close to the soundpipe with an air outlet, and the upper part of the sound pipe and the air outlet are stacked on top of each other, and the two sound producing edges are staggered forward and backward. There are 6 or7 finger holes in the sound tube. The invention relates to the broken-tone wind instrument, wherein the air flow in the resonance box rotates and oscillates and passes through a finger hole, so thatthe sound pipe can be pronounced with a broken sound effect and has better artistic expression.

Description

technical field [0001] The invention relates to musical instruments, in particular to a crappie wind instrument. Background technique [0002] The whistle has a mouthpiece and a cylindrical resonance box, an air outlet is arranged on the upper part of the resonance box, and an elastic ball is arranged in the resonance box. The airflow blown from the mouthpiece into the resonance box revolves in the resonance box and then is discharged from the air outlet. At the same time, the swirling airflow pushes the ball to oscillate back and forth in the resonance box, so that the whistle can produce a broken sound effect with a fixed pitch, but its Different pitches cannot be played. In the traditional edge wind instrument, the airflow passes through the edge structure to excite the air column of the sound pipe, and the fingerholes of different lengths play different pitches, but they cannot play the crunch effect. Contents of the invention [0003] The object of the present inven...
