Dust-proof conductive touch body for precise conductive contact mechanism

Abstract

The dust-proof conductive touch body for the precise conductive contact mechanism includes a dust-proof handle, through which the dust infiltrated under the hammer is covered and blocked in a large area, which solves the weight error caused by the difference in the construction of the keys, resulting in The learner’s playing tactility is wrong, and the dust falls to the bottom and gradually accumulates during long-term use, resulting in fluctuations in the touch reflection time. The problem of scrapping the piano is that after the dust enters the bottom of the keys, the dust-proof handle at the bottom of the keys blocks and closes the dust. Through the vibration of the keys, the scale-like dust-removing sheet on the dust-removing table is lifted. The dust is vibrated out, so that the dust does not accumulate inside, and the rebound speed is fast. The conductive screw can enhance the spring speed of the guide core, greatly speeding up the sounding time of the piano and improving the playing efficiency.

Description

technical field [0001] The invention relates to electronic and electrical equipment, in particular to a dust-proof conductive touch body used for a precise conductive contact mechanism. Background technique [0002] The electronic piano is a commonly used electronic musical instrument, it can provide a playing method close to a piano and a tone close to a piano. For professional pianists, electronic pianos cannot be used as a substitute for pianos, but for piano beginners Or for general enthusiasts, the electronic piano can be used as a low-cost entry-level learning tool for transitioning to the piano. At present, many music schools use ordinary electronic pianos or electric pianos as teaching aids. The internal structure of electronic pianos is precise. Due to a series of rigid requirements for timbre and pitch, the contact time, weight, and The rebound time has very high requirements. Due to the difference in the construction of the keys, there will be a slight weight err...

AI Technical Summary

Problems solved by technology

[0003] In view of the above situation, the technical problem to be solved by the present invention is to provide a dust-proof conductive touch body for a precise conductive contact mechanism. If the player's playing touch is wrong, it will lead to bad playing habits for a long time. During long-term use, dust will fall to the bottom and gradually accumulate, resulting in fluctuations in the touch reflection time. Not good. At present, the dust-proof work is carried out from the outside. Once the dust enters the inside, it cannot be dealt with. Over time, it will cause the wear of the piano keys and even the scrapping of the whole piano.
