Problems solved by technology

[0004] From the above, it can be seen that whether the sound hole cover 413 really seals the sound hole will affect whether the pitch is correct. However, after the sound hole cover 413 is repeatedly moved, its tightness to the sound hole will be reduced, resulting in air leakage, resulting in the emitted sound. Inaccurate, which will affect the performance quality, it needs to be improved

Abstract

The key cup adjustment device for a wind instrument in accordance with the present invention comprises a hinge rod and a key cup assembly. The key cup assembly is mounted on the hinge rod and has at least one solid arm. One end of the solid arm is connected on the hinge rod. The other end of the solid arm is fixedly provided with a key cup. At least one adjusting arm is arranged on the solid arm. The free end of the adjusting arm is located at the outer surface of the key cup and is equipped with an abutting unit. The abutting unit can be adjusted to abut the key cup so the key cup can close a corresponding tone hole tightly and pitches produced by wind instruments are accurate.

Description

technical field [0001] The invention relates to wind instruments, in particular to a sound hole cover adjusting device for a wind instrument which can make the sound hole cover seal the sound hole. Background technique [0002] Wind instruments refer to instruments with a hollow pipe body as a resonance cavity, and wind instruments can be divided into brass instruments and woodwind instruments according to different sounding principles. The sounding principle of woodwind instruments is to blow air into the pipe body. The air column inside the pipe body vibrates to produce sound, and the pipe wall of the pipe body is perforated with a number of sound holes. Opening or closing each sound hole can change the distance of sound waves transmitted inside the pipe body to produce different pitches. Common The most popular woodwind instruments are flute, clarinet, oboe, saxophone and so on. [0003] See Figure 6 As shown, the main structure of the saxophone in the prior art has a p...
