Description

Technical Field

[0001] The utility model belongs to the technical field of musical instrument accessories, and particularly relates to a multifunctional pitch-changing device for an erhu. Background Art

[0002] Patent number: CN201920982287.0, named "Erhu Tuner" utility model patent, announced an erhu tuner. During long-term use, it was found that it has the following disadvantages: 1. At present, erhu instruments generally use silk cotton binding wires, and the strings and the neck are tied together at a certain height of the neck to fix the range of sound. The binding wires of this binding part are commonly known as the "thousand gold" of the erhu. Because the several silk cotton binding wires have obvious shock-absorbing and sound-absorbing effects, the overall resonance effect of the strings and the body of the instrument is significantly weakened, thereby affecting the volume and timbre of the erhu.

[0003] At the same time, since there are certain standard requirements for binding the wire, the operation process is more complicated, making it difficult for performers who do not have certain proficient binding techniques to meet the requirements of standard binding the wire.

[0004] 2. Due to the beautiful sound of the erhu, it has a wide range of uses to express the artistic conception of a piece of music. However, due to the disadvantage that the strings tied to it cannot be moved at will, its expressiveness is limited when playing music.

[0005] 3. The top block of the erhu tuner lacks support. Figure 5 As shown in A in the middle, long-term use will cause the entire tuner to deform, affecting its use. Summary of the Invention
