Novel-structure electric piano keyboard

Abstract

A novel-structure electric piano keyboard comprises parts like black keys, white keys and a chassis. The white keys and the black keys are mounted on the chassis through a front rail, a middle rail and a rear rail, a linkage rod is mounted on a main rail through a linkage shaft frame, a cam is mounted on the main rail through a cam shaft frame, an adjusting button is mounted on the main rail through a crab claw, the main rail is mounted on a support, the upper rail and the lower rail are respectively mounted on the support to limit movement positions of a counterweight hammer handle and a counterweight hammer within a range below the upper rail and above the lower rail, the upper end of an ejector rod is abutted against the cam, a hook and the counterweight hammer handle are fixedly mounted on the cam, the hook contacts with ejector rod skin both before and after the keyboard moves, and the hook breaks away from the ejector rod skin in the movement process of the keyboard; the counterweight hammer handle is fixedly connected with the counterweight hammer, and when the black keys or the white keys are strummed to lower to the bottom, the hook mounted on the cam contacts with the ejector rod skin mounted on the ejector rod to stop return movement of the cam so as to prepare for next stressed movement of keys; when fingers of a player leave the keys, the hook can push the ejector rod back to an original position to enable keyboard structure to quickly restore to an original position.

Description

technical field [0001] The invention relates to an electric piano keyboard, in particular to a novel electric piano keyboard structure. Background technique [0002] The piano is well-known in the music world for its wide range, beautiful timbre and unique performance performance, and is known as the king of musical instruments. However, according to the investigation and research on the musical instrument market at home and abroad in recent years, because the manufacture of traditional pianos consumes a large amount of wood resources, the production process is complicated, and labor costs increase, the price of traditional pianos is relatively high, and its sales ratio in the musical instrument market is declining year by year. With the wide application of large-scale integrated circuits, the maturity of traditional piano sound sampling technology and the development of digital circuit simulation of traditional piano playing technology, the sound and effect of electric pia...

Problems solved by technology

However, compared with traditional pianos, the commonly used electric piano keyboards lack a rich touch feeling and cannot change with changes in playing strength and speed, causing electric piano learners to be unable to adapt to traditional pianos due to long-term use The playing feeling of the piano keyboard, especially in competitions, performances and other occasions, due to the difference in the habit of playing the touch, it is impossible to use the high-end traditional piano to play the ideal effect, which also leads to the lack of rich playing strength of the traditional piano learners due to the lack of rich playing strength of the electric piano keyboard. Feelings and unwillingness to use the electric piano, etc.
