Electrode fixing device for soundboard for musical instrument with eight categories processing

Abstract

The invention discloses an electrode fixing device that is used for the processing of serinette sound boards and comprises an electrode holder, an electrode, a spring, a screw rod and a nut, one end of the electrode is a flat electrode head and runs through a corresponding slot in the electrode holder, the other end of the electrode takes a shape of a hollow cylinder and is sleeved on the screw rod, the spring is sleeved on the screw rod and has an upper end that presses on a cylindrical end of the electrode and a lower end that is limited by the screw rod, and the upper end of the cylindrical end of the electrode is limited by the nut. The electrode fixing device has following advantages: 1 the electrode fixing device can ensure the processing quality of voice keys, has convenient adjustment and better applicability, and is applicable to the frequency modulation processing of almost all the different sound boards; 2 the electrode fixing device can process multiple voice keys simultanesouly and simplify multiple electrode fixing devices that are required originally into a single device, thus having miniaturized processing equipment, simplified structure, lowered production cost, improved working efficiency and had higher economic benefits.

Description

Technical field [0001] The invention relates to a processing device for the soundboard of an eight-tone piano, in particular to a device capable of fixing electrodes in the processing of the soundboard. Background technique [0002] The keys of the soundboard of the eight-tone piano are generally treated by electrode corrosion. The electrodes will be worn out during the process, so the distance between the electrodes and the keys of the soundboard will also change, which will affect the processing effect and quality, and the electrodes need to be adjusted in time The distance between the keys on the soundboard. [0003] The existing electrode fixing devices are all fixed, and the distance between the electrode and the key of the processed soundboard cannot be adjusted at any time, and therefore cannot be adjusted with the adjustment of the working state. In addition, because there are many types of sound keys, different types of sound keys require different requirements for the h...

AI Technical Summary

Problems solved by technology

[0002] The keys of the octave soundboard are generally processed by electrode corrosion. During the process, the electrodes will be worn out, so the distance between the electrodes and the soundboard keys will also change, which will affect the processing effect and quality. It is necessary to adjust the electrodes in time Distance from soundboard keys

[0003] The existing electrode fixing devices are all fixed, and the distance between the electrode and the key of the soundboard to be processed cannot be adjusted at any time, so it cannot be adjusted with the adjustment of the working state

In addition, because there are various types of keys, different types of keys need to have different requirements for the height of the electrode and the distance between the electrodes, so the fixed electrode fixing device cannot adapt to various types of keys. needs

[0004] Also because the existing electrode fixing device can only fix a single electrode, it can only process a single key in the soundboard when processing each time, but cannot process a plurality of keys at the same time, so the processing efficiency is very low
