Electric piano keyboard with self-locked keys

Abstract

The invention discloses an electric piano keyboard with self-locked keys. The electric piano keyboard comprises a piano, wherein a supporting device is fixedly connected to the lower side wall of thepiano; the keyboard is fixedly connected to the piano; key grooves are formed in the keyboard; limiting grooves are symmetrically formed in the side walls of the key grooves; a limiting device is fixedly connected to each limiting groove; a key pipe is connected to each key groove in a sliding manner; a plurality of slots are symmetrically formed in the side wall of the key pipe; a supporting plate is slidably connected in the key pipe; the keys are fixedly connected to the upper end of the supporting plate; and a telescopic cavity is formed in the supporting plate. The keys are simply detached. When the keys on the electric piano keyboard are damaged or stained, the keys can be taken down easily from the keyboard to be maintained and cleaned; then the processed keys are mounted on the keyboard to be used again, so that the sounding of the piano is not affected, and the piano playing effect is improved.

Description

technical field [0001] The invention relates to the technical field of keyboards, in particular to an electric piano keyboard with self-locking keys. Background technique [0002] The sounding principle of the electric piano is to use the keyboard as an on-off switch to form electrophoresis. Once the key on the keyboard is pressed, the internal crystal oscillator starts to work, forming a pulse to generate a waveform of a certain frequency, which is then amplified by the frequency divider and sent to the speaker for sound. , Most of the modern electric piano keyboards are integrated with the keys on the keyboard. It is troublesome to disassemble and assemble the keys. When the keys are damaged or stained, it is inconvenient to repair and clean the keys, which will affect the pronunciation of the piano, thus Affects the pianist's piano performance. Contents of the invention [0003] The purpose of the present invention is to solve the existing problems in the prior art, su...
