Description

Auto Correction Piano

technical field

The invention relates to the field of piano teaching, in particular to an automatic error-correcting piano.

Background technique

The piano (Italian: pianoforte) is a keyboard instrument in Western classical music, known as the "King of Musical Instruments", consisting of 88 keys (52 white keys, 36 black keys) and a metal string soundboard.

As one of the representative musical instruments of elegant art, many parents want their children to have "intimate contact" with it. Therefore, the market for piano teaching is getting bigger and bigger. In the current piano teaching, the commonly used piano is an old-fashioned piano.

detailed description

The present invention will be further described below in conjunction with embodiment, but is not limited to the content on the description.

As shown in Figures 1 and 2, a kind of automatic error correction piano, it comprises piano body 1, touch display screen 2, pressure sensor 3, speech recognizer 4 and circuit board 5, touch display screen 2 is installed on piano body 1 The front end of the upper door 11 middle part, the pressure sensor 3 is installed on the bottom of the key 12 of the piano body 1, and is connected with the circuit board 5 through the data line, and the voice recognizer 4 is installed on both sides of the touch display screen 2 and connected with the circuit through the data line The board 5 is connected, and the circuit board is installed on the inside of the upper door 11 of the piano body 1. A central processing module 51, a storage module 52, a control module 53 and a data conversion module 54 are installed on the circuit board 5. One end of the data conversion module 54 is connected to the pressure sensor 3 It is connected with speech recognizer 4, and the other end is connected with central processing module 51, and central processing module 51 is respectively connected with storage module 52 and control module 53, and storage module 52 and control module 53 are connected with touch screen 2 simultaneously.

The upper door 11 of the piano body 1 is hinged on the top cover 13 of the piano body 1, and the angle between the upper door 11 and the top cover 13 can be adjusted so that the touch screen 2 and the player's eye view angle are the best, which is beneficial to the player. The music score displayed in the touch display screen 2 can be seen clearly and accurately.
