Embodiment 1

[0030] like Figure 1-4 As shown, a voltage-stabilizing flute, the body 1 is a flute, and the inner wall of the flute body of the body 1 has an arc-shaped opening groove 2, and the arc-shaped opening groove 2 is provided with two sets of insertion sliders 3, and the arc-shaped opening groove 2 A lightweight spring 4 is connected between the plug-in slider 3, and the outer wall of the arc-shaped opening groove 2 is provided with a slide-assisting groove 5, and the side of the plug-in slider 3 close to the slide-aiding groove 5 is provided with a slide-assisting block 6 to facilitate sliding. The groove 5 is in contact with the slider 6, the outer end of the plug-in slider 3 is provided with an air guide plate 7 in contact with the inner wall of the flute body, and the outer wall of the flute body of the main body 1 is provided with a corresponding arc-shaped opening groove 2. A rectangular opening communicating with it Groove and be used for installing air-permeable film 8.

Embodiment 2

[0032] On the basis of Embodiment 1, the arc-shaped opening groove 2 is on the opposite surface of the sound hole of the flute body.

Embodiment 3

[0034] On the basis of Embodiment 1, the angle of the contact end of the arc-shaped opening groove 2 with the plug-in slider 3 and the contact end of the air guide plate 7 with the inner wall of the flute body are all set with rounded corners.

Abstract

The invention relates to the technical field of woodwind instruments, and discloses a pressure-stabilizing type flute. The body is a long flute, an arc-shaped opening groove is formed in the inner wall of the flute body, two groups of inserting sliding blocks are arranged in the arc-shaped opening groove, and light springs are connected between the arc-shaped opening groove and the inserting sliding blocks, and a sliding-assisting groove is formed in the outer wall of the arc-shaped opening groove. Sliding-assisting blocks are arranged on the inserting sliding blocks on the sides close to thesliding-assisting groove, and the sliding-assisting groove is in contact with the sliding-assisting blocks, and an air guide plate which is in contact with the inner wall of the flute body is arrangedat the outer end of the inserting sliding blocks. A rectangular opening groove communicated with the arc-shaped opening groove is formed in the outer wall of the flute body, and the rectangular opening groove is communicated with the arc-shaped opening groove and is used for installing a breathable film. The problem that the pressure of the air column is not enough and pitch bend error occurs dueto insufficient air supply of a lung cavity when playing a long flute for a long time is solved. The pressure-stabilizing type flute has the effect of guiding outside air flow and enhancing the air pressure in the flute cavity, and the effect of pressure stabilization is achieved.

Description

technical field [0001] The invention relates to the technical field of woodwind instruments, in particular to a voltage-stabilizing flute. Background technique [0002] Woodwind instruments have a wide range, soft timbre, and strong expressiveness. They play an important role in ensembles and are also important solo instruments. For example, the flute produces sound by forming an air column vibration in the flute cavity when playing, and all flutes have different air column lengths due to the length of the flute cavity and the conversion of different sound zones, resulting in different air pressure strengths required. Be cautious when jumping to another range, but long-term performance will inevitably lead to insufficient air supply to the lung cavity, which is prone to mistakes in sound transfer. Contents of the invention [0003] (1) Solved technical problems [0004] Aiming at the deficiencies of the prior art, the present invention provides a pressure-stabilizing flu...
