Problems solved by technology

Although the sound of Guzheng or Guqin depends on the selection of materials and craftsmanship, it is also affected by other factors. Therefore, there is no standard data in the production process, only empirical data. Once the product is formed, the sound quality is also qualitative, and it is used to improve the sound quality. very limited

Embodiment 1

[0014] Embodiment 1: a kind of adopting such as figure 1 The resistance volume adjustment mechanism shown is suitable for guzheng or guqin musical instruments. The mechanism is installed in the sound cavity of the corresponding musical instrument to appropriately increase the sound resistance and resonance of the sound cavity and improve the stability of the tone and sound. It is best to install near the sound outlet, or replace the connecting column 1 with a sky post or a ground post, or independently install it in the sound cavity section area near the sky post or ground post. Between the upper wall (panel) and the lower wall (bottom plate) of the sound cavity of the corresponding musical instrument, the connecting column 1 is fixed (the sound transmission column of the existing sound cavity can also be used, such as the sky column or ground column of the Guqin). The connecting column 1 is designed to be cylindrical, and the external gear sleeve 2 is set on the outside of th...

Embodiment 2

[0016] Embodiment 2: Carry out appropriate modification on the basis of Embodiment 1, replace the elastic traction parts with extension springs or rubber belts, and the outer ends of the traction ropes 5 on both sides are respectively connected to corresponding extension springs or rubber belts, and the extension springs or rubber belts on both sides The rubber bands are respectively fixed on the walls of the sound cavity at symmetrical positions on both sides of the connecting column 1 .

Abstract

The invention discloses a sound cavity resistance volume adjusting mechanism of musical instruments such as a zither, wherein a connecting column is fixed between an upper wall and a lower wall of a sound cavity; an outer gear sleeve sleeves the connecting column; a left sound insulation cloth leaf and a right sound insulation cloth leaf are symmetrically fixed on the circumferential side surfaceof the outer gear sleeve; two outer ends of the left sound insulation cloth leaf and the right sound insulation cloth leaf are connected with traction ropes respectively; outer ends of the traction ropes at two sides are connected with elastic traction components respectively; a driving mechanism for driving the outer gear sleeve to rotate and stagnate is arranged on a sound cavity wall at one endof the connecting column. The mechanism can be applied to the sound cavity of the zither or a Guqin, and is used for increasing the sound resistance and resonance of the sound cavity properly, the stability of the sound color and the sound are improved, the sound resistance degree can be adjusted according to characteristics of different zithers or Guqin, and the optimal configuration is achieved.

Description

technical field [0001] The invention belongs to the technical field of auxiliary accessories for musical instruments, and in particular relates to an instrument suitable for adding sound-resistance materials in a sound chamber of a guzheng musical instrument and improving the sound quality by adjusting the resistance volume. Background technique [0002] Guzheng or guqin is a traditional musical instrument. There are various production techniques, but they are all relatively mature techniques. The production level of guzheng or guqin is mainly reflected in the selection of materials and the control of panel thickness. For example, the texture and size are taken from the roots of trees, The middle part and the tip part are different, whether it is facing the sun or facing the sun, the sound range and the thickness of the panel are different. Or by changing the selection of materials such as red sandalwood, nanmu, mahogany and other precious materials. The focus of traditiona...
