[0037] Reference Figure 1 and Figure 2 A circuit board 4 is bolted inside the keyboard housing 1, a memory module 5 is electrically connected to the circuit board 4, a light ring 7 electrically connected to the circuit board 4 is arranged on the key 2, the circuit board 4 can control the power-on sequence of the light ring 7 of the key 2 on the keyboard housing 1, and a power module 20 electrically connected to the circuit board 4 is arranged inside the keyboard housing 1.

[0038] Reference Figure 1 and Figure 2 The keyboard housing 1 is provided with a playback knob 8 electrically connected to the circuit board 4. The playback knob 8 is used to call out the melody information stored in the memory module 5. External expansion boards 21 are welded on both sides of the keyboard housing 1. A 3.5mm microphone input and output port is arranged on the external expansion board 21. A speaker 6 electrically connected to the circuit board 4 is bolted to the external expansion board 21. An external socket 22 is bolted to the external expansion board 21. The external socket 22 can adopt the USB interface in the existing technology.

[0039] When the user needs to relax, the user presses the switch button 3, which switches the output signal of the button 2. The user then uses the button 2 to improvise. Each time the user presses the button 2, the light ring 7 on the button 2 will light up in sequence. When a good song is created, the user turns the playback knob 8.

[0040] The playback knob 8 feeds back the signal to the circuit board 4, the circuit board 4 calls the tune information stored in the memory module 5, and at the same time, the circuit board 4 powers the ring 7 on the button 2 according to the sequence of the button 2. The user only needs to press the button 2 according to the sequence of the ring 7 on the button 2, and then the user can export the created tune through the external socket 22.

[0041] With reference to Figure 1 , Figure 2 and Figure 3 , the keyboard shell 1 is provided with a receiving shell 9, a horizontal receiving shaft 10 is arranged on the receiving shell 9, a flexible display screen 11 connected to the circuit board 4 is wound on the receiving shaft 10, an avoiding slot 12 is formed on the receiving shell 9 for the flexible display screen 11 to pass through, an end rod 13 is attached to one end of the flexible display screen 11 away from the receiving shaft 10, and a supporting rod 14 is arranged on the receiving shell 9 in a rotating manner. An insertion slot 15 is formed on the end rod 13 for the end of the supporting rod 14 to be inserted.

[0042] With reference to Figure 2 , Figure 3 and Figure 4 , the receiving shell 9 is provided with a tensioning piece 16 for adjusting the tension of the flexible display screen 11, the tensioning piece 16 includes a coil spring 161 welded on the receiving shaft 10, a fixed column 162 is welded on the receiving shell 9, one end of the coil spring 161 away from the receiving shaft 10 is welded on the fixed column 162, a rod receiving groove 17 is formed on the receiving shell 9 for accommodating the supporting rod 14, a first magnet 18 is attached to the end rod 13, and a second magnet 19 magnetically attracted to the first magnet 18 is attached to the receiving shell 9.

[0043] The user rotates to open the supporting rod 14, and then pulls the end rod 13, so that the insertion slot 15 on the end rod 13 is sleeved on the end of the supporting rod 14. In this process, the flexible display screen 11 drives the receiving shaft 10 to rotate, and the receiving shaft 10 drives the coil spring 161 to elastically deform, so that the flexible display screen 11 is kept in a tensioned state. When the user creates a tune, the characters on the button 2 and the sequence will be displayed on the flexible display screen 11 in turn.

[0044] When the user presses the created tune again, the flexible display screen 11 will display the characters on the button 2 pressed by the user again. When the user modifies the music score, the flexible display screen 11 can intuitively display the position and characters modified by the user. When the user removes the end rod 13, the coil spring 161 restores the deformation and drives the receiving shaft 10 to wind the flexible display screen 11, until the first magnet 18 and the second magnet 19 are attracted together. At this time, the end rod 13 is tightly attached to the receiving shell 9.

[0045] The implementation principle of the music keyboard is as follows: when the user needs to relax, the user presses the switching button 3, the switching button 3 switches the output signal of the key 2, then the user uses the key 2 to create freely, the lamp ring 7 on the key 2 is lit in turn each time the user presses the key 2, when a good tune is created, the user rotates the playback knob 8.

[0046] The playback knob 8 feeds back the signal to the circuit board 4, the circuit board 4 calls the tune information stored in the memory module 5, at the same time, the circuit board 4 powers the lamp ring 7 on the key 2 according to the sequence of the key 2, the user only needs to press the key 2 according to the sequence of the lamp ring 7, then the user can export the created tune through the external socket 22.

[0047] The user rotates the support rod 14, then pulls the end rod 13, the slot 15 on the end rod 13 is sleeved on the end of the support rod 14, in this process, the flexible display screen 11 drives the storage shaft 10 to rotate, the storage shaft 10 drives the coil spring 161 to be elastically deformed, so that the flexible display screen 11 is kept in a tension state, when the user creates a tune, the characters and the sequence on the key 2 are displayed in turn on the flexible display screen 11.

[0048] When the user presses the created tune again, the flexible display screen 11 displays the characters on the key 2 again, when the user modifies the music score, the flexible display screen 11 can intuitively display the position and the character modified by the user, when the user removes the end rod 13, the coil spring 161 restores the deformation and drives the storage shaft 10 to wind the flexible display screen 11, until the first magnet 18 and the second magnet 19 are attracted together, at this time, the end rod 13 is close to the storage shell 9.

[0049] The above are preferred embodiments of the present application, which do not limit the protection scope of the present application, therefore: all equivalent changes made on the structure, shape and principle of the present application should be covered in the protection scope of the present application.
