[0013] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0014] See also Figure 1-Figure 9 The present invention provides a technical solution: a musical note key, comprising a background board 1 and a music box 2, A plurality of music boxes 2 are arranged on one side of the background board 1, a music ball 3 is arranged on the top of the music box 2, a plurality of through holes 4 are arranged inside the background board 1, and the plurality of through holes 4 are evenly distributed on the background board 1, the music box 2 comprises a box body 21 arranged on one side of the background board 1, a recess 22 for the electromagnetic field is arranged on the top of the box body 21, a circuit board a23 is installed inside the box body 21 by screws, a speaker 24 is installed on one side of the circuit board a23, and a switch 25 is arranged on one side of the speaker 24; One side of the switch 25 is fixedly connected to the circuit board a23, and both sides of the circuit board a23 are fixedly connected with LED lamp beads 26; the side of the circuit board a23 away from the speaker 24 is fixedly connected to the charging socket 27, and the side of the circuit board a23 close to the charging socket 27 is installed with an electromagnetic coil 28; a button 29 is installed on the top of the music box 2, and the output end of the button 29 is electrically connected to the circuit board a23, and one side of the box body 21 is fixedly connected to a fixing plate 210; one end of the fixing plate 210 is fixedly connected to a fixing fork 211, and the fixing fork 211 is provided with two groups and is symmetrically distributed about the central axis of the fixing plate 210, and the outer side of the fixing fork 211 is plugged into the through hole 4 of the background board 1; the music ball 3 includes a silicone sleeve 31 that is rollingly connected to the top of the box body 21, and the center of the silicone sleeve 31 is wrapped with an iron ball 32, and the inside of the silicone sleeve 31 is installed with a circuit board b33.

[0015] In specific implementation, the note key can be used to insert the fixing forks 211 on one side of multiple groups of music boxes 2 into the through holes 4 of the background board 1 to fix the music boxes 2. The basic music boxes 2 are 63, including eight high, medium and low notes, fifteen semitones, and twelve ultra-low or ultra-high notes. Consumers can also choose more music boxes 2 according to their needs. The music boxes 2 of each piece of music are arranged from left to right or from top to bottom on the background board 1. After the arrangement is completed, the music ball 3 can be placed on the top music box 2. At this time, the music boxes 2 will move and jump on different music boxes 2. When the marble falls into the electromagnetic field concave position 22 of the music box 2, the electromagnetic coil 28 can absorb and release the marble, and the time of absorbing and releasing the marble can be controlled, with four gears of 0.25 seconds, 0.5 seconds, 0.75 seconds and 1 second respectively. The switch 25 can control the light, magnetism and sound to start at the same time, and the LED lamp bead 26 will emit light and pass through the transparent PP material music box 2 to the outside, and the sound will be recorded in the electronic chip and output through the speaker 24. Therefore, when the music ball 3 falls on the music box 2, it will emit sound and light, so as to perform, which is one of the performance methods; The second playing method is to close the music box 2 and start the music ball 3. When the music ball 3 falls on the music box 2, the circuit board b33 in the music ball 3 will make a sound through the sound-emitting component, thereby performing the music. The through holes 4 are grouped into three, and the three groups of through holes 4 are combined into a triangle, and the distances between adjacent center points of the three groups of through holes 4 are the same. When it is necessary to adjust the angle of the music box 2 to change the moving trajectory of the music ball 3, the music box 2 is pulled to drive the fixing fork 211 to disengage from the engagement with the through hole 4, and the fixing fork 211 is rotated 45° and inserted into the through hole 4 again to tilt the music box 2, thereby completing the adjustment of the music box 2. In this way, through the above operations, consumers can adjust the music device to various music they want to play based on simple music knowledge, and then enjoy the music, thereby satisfying consumers' high-end needs for self-entertainment.

[0016] In summary, by arranging and fixing multiple groups of music boxes 2 on the background board 1, and then pushing the music ball 3 to jump on the music box 2, sounds are produced for performance.
