[0002] The percussion piano, also known as the "percussion piano", is a very ancient musical instrument that has existed for thousands of years and is mostly used for children's music enlightenment.

[0003] For example, a new type of percussion toy piano with the authorization announcement number "CN203169996U" is provided. The sleeve holes at both ends of the sound-producing steel bar correspond to the bolt holes on the first rod frame and the bolt holes on the second rod frame respectively, and are fixed by installing bolts. This provides a new type of percussion toy piano that can be played without battery power, has a simple structure, is sturdy and not easy to be broken by children. When in use, different high and low tones of music can be heard by simply striking the sound-producing steel bars of different lengths. However, when the percussion toy piano is in use, the percussion plate is fixed with bolts, which will cause the percussion plate to vibrate, and this vibration will cause the bolt to resonate. In this resonant state, the friction coefficient between the bolt and the percussion plate will change, which will cause the bolt to loosen, and then the percussion plate to loosen, resulting in changes in the sound of the percussion toy piano, affecting the normal use of the percussion toy piano.

[0018] The present invention will be further described below with reference to the accompanying drawings: Example 1

[0019] See also Figure 1-4 : In this embodiment, a luminous percussion toy piano includes a straight board 1 and a horizontal board 4. The front and rear ends of the two straight boards 1 are respectively fixedly connected to the inner top of the two horizontal boards 4. The top of the straight board 1 is attached with a top board 6, and the top circular mouth of the top board 6 is connected to a fixed structure 2. The bottoms of the two horizontal boards 4 are respectively fixed with bases 5, which support the horizontal boards 4. The right side of the horizontal board 4 is connected to a luminous structure 3.

[0020] The fixing structure 2 includes a bracket 201 and a curved plate 202. The outer wall of the bracket 201 is plugged into the top circular opening of the top plate 6. The bracket 201 has openings on the front and back sides. The tops of the left and right sides of the bracket 201 are respectively fixed to the inner side of the curved plate 202. The inner wall of the bracket 201 is threaded with bolts 203. The bolts 203 are forced to rotate up and down through the inner wall of the bracket 201. The bottom of the outer wall of the bracket 201 is plugged into the top circular opening of the straight plate 1.

[0021] The bracket 201 in the fixing structure 2 passes through the circular opening of the outer wall of the top plate 6 from top to bottom and is plugged into the circular opening on the top of the straight plate 1. At this time, the bottom of the curved plate 202 fits against the top of the top plate 6, and then the bolt 203 is threadedly connected to the inner wall of the bracket 201 from top to bottom. As the bolt 203 is gradually screwed into the inner wall of the bracket 201, the bracket 201 will expand outward, so that the outer wall of the bracket 201 is tightly pressed against the circular openings of the outer walls of the straight plate 1 and the top plate 6. At the same time, the nut on the top of the bolt 203 is tightly pressed against the top of the curved plate 202, which increases the expansion and tightening inside the circular opening, increases the friction contact surface, can effectively prevent the bolt from loosening, ensure the percussion sound of the toy piano, and ensure the normal use of the percussion toy piano.

[0022] A hammer body 7 is attached to the left side of the top of the rear top plate 6. The hammer body 7 is a rubber block. A handle 8 is fixed to the left side of the hammer body 7. The handle 8 facilitates the movement of the hammer body 7. The light-emitting structure 3 includes a block 301 and a beam plate 302. The left side of the outer wall of the block 301 is plugged into the right groove of the cross plate 4. The right side of the block 301 is fixed to the left end of the beam plate 302.

How to operate and use the induction lamp 303 is already an existing technology, and no further explanation will be given. The model can be selected according to usage requirements.

[0023] Working principle:

[0024] Installation of percussion toy piano:

[0025] Make the bottoms of multiple top plates 6 fit with the tops of straight plates 1, align the circular openings on the outer walls of top plates 6 with the circular openings on the tops of straight plates 1, and then pass the bracket 201 from top to bottom through the circular openings on the outer walls of top plates 6 and plug into the circular openings on the tops of straight plates 1. At this time, the bottom of the curved plate 202 fits with the top of top plate 6, and then the bolts 203 are threadedly connected with the inner walls of the bracket 201 from top to bottom. As the bolts 203 are gradually screwed into the inner walls of the bracket 201, the bracket 201 will expand outward, so that the outer walls of the bracket 201 are tightly pressed against the circular openings on the outer walls of straight plates 1 and top plates 6. At the same time, the nut on the top of the bolt 203 is tightly pressed against the top of the curved plate 202. Then, plug the outer wall of the block 301 into the right notch of the base 5 to complete the installation of the beam 302 and the induction lamp 303.

[0026] Use of percussion toy piano:

[0027] The user holds the handle 8 and lifts the hammer 7. When the hand reaches above the induction lamp 303, the internal infrared sensor detects that an object is approaching and transmits a signal to the control circuit. The control circuit lights up the lamp beads inside the induction lamp 303. At this time, the user's hammer 7 strikes the corresponding top plate 6 to produce a sound. Since the top plates 6 are of different lengths, the sounds produced after striking are different, which can form music. Example 2

[0028] See also Figure 1-4 In the present embodiment, a luminous percussion toy piano further comprises a groove plate 9, wherein the front and rear right sides of the two groove plates 9 are respectively fixedly connected to the left bottom sides of the two bases 5.

[0029] Working principle:

[0030] The inner wall of the groove plate 9 can be plugged into the edge of the table or the outer wall of the rod, which increases the fixing form of the percussion toy piano and avoids it being unable to be used when there is no supporting surface.

[0031] While the present invention has been shown and described with reference to preferred embodiments, it will be understood by those skilled in the art that various changes in form and details may be made therein within the scope of the claims.
