Problems solved by technology

The piano is very professional, and not everyone can play it perfectly. Therefore, when people want to listen to the piano performance, people must go to a concert to hear it. In practice, the repertoire to be played is predetermined in advance, and the music cannot be played according to the preferences of the audience, so that the user cannot be given a better user experience.

Abstract

The invention discloses an automatic piano playing device. The device comprises a supporting plate, the front surface of the supporting plate is provided with a plurality of longitudinal chutes whichare equal to piano keys in number and are in one-to-one correspondence with the piano keys in position. Each chute is connected with a sliding block in a sliding mode. A pressing block used for pressing the piano keys is fixed below the part, located on the outer side of the chute, of the sliding block. First solenoid coils are arranged on the sliding blocks, the first solenoid coils are electrically connected with the power supply device through first relays, a fixing block is arranged above each chute, second solenoid coils are arranged below the fixing blocks, the second solenoid coils areelectrically connected with the power supply device through second relays, and a touch display is arranged on the back face of the supporting plate. The piano is automatically played according to theselected tracks, the supporting plate is clamped on the piano through the clamping structure, the central processing unit automatically presses the keys through the electromagnetic technology to enable the piano to be automatically played, and the selected tracks are played.

Description

technical field [0001] The invention relates to the field of performance devices, in particular to an automatic piano performance device. Background technique [0002] Piano is a kind of keyboard musical instrument, needs people to play and just can send out moving sound, therefore, most people also like to listen to the solo of piano very much, can give the feeling of pleasing to the eye like this. The piano is very professional, and not everyone can play it perfectly. Therefore, when people want to listen to the piano performance, people must go to a concert to hear it. In fact, the repertoire to be played is predetermined in advance, and the music cannot be played according to the preferences of the audience, so that the user cannot be given a better user experience. Contents of the invention [0003] The purpose of the present invention is to overcome the problems existing in the above-mentioned prior art, provide a kind of automatic piano playing device, carry out au...
