Description

Technical Field

[0001] The utility model relates to the field of pianos, in particular to a piano for assisting blind people in playing the piano. Background Art

[0002] The piano, known as the "King of Musical Instruments", was invented by the Italian Bartolomeo Cristofori in 1709. It combines a sophisticated mechanical structure with high-quality wood, metal and other materials. Through the coordinated work of keys, strings, soundboard and action system, it produces rich, diverse and expressive timbres. The piano is widely used in solo, duet and accompaniment performances, and is an indispensable and important instrument in music creation and performance.

[0003] Existing pianos used to assist blind people in playing the piano can directly control the changes in sound by touching the keys with fingers. However, when piano beginners learn to play the piano, they need to identify the key positions, locate the fingers, and control the force. However, when blind people learn to play the piano, due to visual impairment, it is difficult to identify the key positions and locate the fingers, which reduces the convenience of using the piano. Utility Model Content

[0004] Based on this, the purpose of the present invention is to provide a piano for assisting the blind in playing the piano, so as to solve the technical problem that the blind have difficulty in identifying the key positions and positioning their fingers due to visual impairment.
