Detailed Description

A detailed description will be given below of a specific embodiment of the present invention with reference to the accompanying drawings. The detailed description is only for more clearly illustrating the technical solution of the present invention, and therefore, the specific description is only for example and the protection scope of the present invention is not limited thereby.

It is to be noted that unless otherwise specified, technical or scientific terms used herein shall have the ordinary meaning as understood by those skilled in the art to which the present invention belongs. In addition, in the drawings, the elements or portions are not necessarily drawn to actual scale.

As shown in fig. 1, the present embodiment provides an electric piano with automatic accompaniment, which comprises an electric piano body 1 including a case, a key region, a functional region provided on the upper surface of the case, and a circuit board built in the body.

The function area is provided with a playing mode selection area 3, an emotion mode selection area 4, a speed selection area 5, a beat selection area 6 and a tone selection area 7.

The playing mode selection area 3 is provided with a 'normal mode' button and an 'accompaniment mode' button. Before playing, if the 'normal mode' is selected, playing normally. If the 'accompaniment mode' is selected, the device emits the accompaniment corresponding to the played music according to the accompaniment sound source stored in the chip on the circuit board, and the player does not need to accompany by himself.

Preferably, the emotion mode selection area 4 is provided with a "lyric" button, a "cheerful" button, a "flick" button, a "singing" button, and a "songbook" button.

The music styles of different songs may be different, for example, a child song is played, and a 'child song' button needs to be pressed before playing so that the music style of the accompaniment is consistent with the music style of the played song, and the accompaniment effect is better.

Preferably, the speed selection area 5 is provided with a "speed +" button and a "speed-" button.

The playing speed can be changed according to the requirements of players, the playing speed is high, and the speed plus button is pressed to accelerate the accompaniment speed. Otherwise, the playing speed is slow, and then the speed button is pressed down to slow down the accompaniment speed, so as to meet the playing requirement of the player.

Preferably, the tempo selection section 6 is provided with an "4/4" button, a "3/4" button, a "2/4" button, a "3/8" button, and a "6/8" button.

The beats of different songs may be different, and the corresponding accompaniment beat is selected according to the beat of the played song, so that the accompaniment effect is further improved.

Preferably, the tone selection area 7 is provided with a "C" button, a "D" button, an "E" button, an "F" button, a "G" button, an "a" button, a "B" button, a "down D" button, a "down E" button, a "down G" button, a "down a" button, and a "down B" button.

The tones of different songs are possibly different, and the corresponding accompaniment tones are selected according to the tones of the played songs, so that the accompaniment effect is further improved.
