Adjustable sound head button

Abstract

The invention relates to an adjustable sound head button. The adjustable sound head button comprises a sound head button, a damper and a sound head button panel, wherein the sound head button is a T-shaped structure in which two cylinders are connected, a horizontal jack is arranged in middle of one end of a horizontal cylinder, a vertical jack is arranged in middle of the lower end of a verticalcylinder, a metal cutting inserted into the horizontal jack is arranged at one end of the damper, a first lock screw is mounted with bottom put against the metal cutting in middle of the upper end ofthe horizontal cylinder of the sound head button, a sound head button panel is installed at one side of the damper near the sound head button, a sound making screw rod is installed at lower end of thevertical cylinder of the sound head button, a metal cutting with one end inserted into the vertical jack is arranged at lower end of the sound making screw rod, and a second lock screw is mounted with one end put against the metal cutting of the sound making screw rod in middle opposite to the damper on the vertical cylinder of the sound head button. The adjustable sound head button has the characteristics of improving operating angle and adjusting speed of the damper, optimizing process, improving production efficiency, reducing difficulty of maintenance of after-sales maintenance personnel,and being more environment-friendly.

Description

technical field [0001] The invention relates to the technical field of upright piano damping components, in particular to an adjustable tone head knob. Background technique [0002] Nowadays, pianos have entered thousands of households, and the production volume of piano factories is increasing year by year. However, the production process and parts of traditional pianos are still made of wood and glued together. It is time-consuming and labor-intensive for later maintenance and fine adjustment in the production process. . As far as the damper is concerned, its main function is to suppress the vibration of the strings. If there is a gap or a small contact area between the damper felt and the strings, it will directly cause the piano to be unable to stop the sound. The traditional process uses pinch-bending pliers to adjust the bending degree of the damper screw to adjust the alignment of the damper felt and the strings. The bending angle is completely dependent on the feel ...

[0002] Nowadays, pianos have entered thousands of households, and the production capacity of piano factories is increasing year by year. However, the production process and parts of traditional pianos are still made of wood and glued together. It is time-consuming and laborious for later repairs and fine adjustments in the production process.

As far as the damper is concerned, its main function is to suppress the vibration of the strings. If there is a gap or a small contact area between the felt of the damper and the strings, it will directly cause the piano to be unable to dampen the sound.

The traditional craft uses pinch bending pliers to adjust the bending degree of the damper screw to adjust the alignment between the damper felt and the strings. The bending angle is completely based on the worker's feel and experience, and often needs to be adjusted back and forth, which takes a lot of man-hours; after-sales service of various piano shops Due to limited skills, maintenance personnel often need to be trained in the factory for a long time before they can master certain skills
