[0002] Illuminated piano keys have long been a popular choice; they not only make playing along with a digital piano more engaging, but also provide essential visual guidance for players in dark environments. However, while the current approach—directly attaching LED lights to the transparent or translucent underside of the keys—is simple and easy to implement, it also has certain drawbacks.

[0003] The lighting effect is not uniform and obvious enough; due to the position and brightness limitations of the LED lights, the lighting effect of the keys often presents "hot spots" and "dark areas"; this not only affects the overall aesthetics, but may also interfere with the player's visual judgment.

[0026] Example 2:

[0027] See also Figures 1 to 5 Compared with the first embodiment, the present invention is a digital piano with light-guiding keys. The present embodiment further comprises: a key body 41 is rotatably provided on the top side of the lower shell 1 of the piano frame; a transparent light guide plate 42 with a dispersed light source function is fixedly mounted on the top of the key body 41, and an array of columnar reflectors is arranged inside the transparent light guide plate 42, and the surface of the transparent light guide plate 42 is frosted. A concave semicircle 43 is opened on one side of the top of the key body 41, and the transparent light guide plate 42 is fixedly mounted on the concave semicircle 43. The side opening of the transparent light guide plate 42 is fixedly mounted on the concave semicircle 43. At the same height; a rotating frame 44 is fixedly provided at the end of the key body 41, and the rotating frame 44 is fixed to the reset part on the inner side of the lower shell 1 of the piano frame, the squeezing button at the bottom of the key body 41 is fixed to the PCB signal board 45 through a cable, and the PCB signal board 45 is fixedly connected to the function key board 31 through a cable, the bottom of the function key board 31 is fixedly connected to the LED light board 46 through a cable, and the LED light board 46 is fixedly installed inside the lower shell 1 of the piano frame, and the LED light board 46 lamp beads are at the same height as the side opening of the transparent light guide plate 42 and the concave semicircle 43.

[0028] The reset member on the inside of the lower case 1 is a weight, which is mounted on the rotating shaft of the rotating frame 44. One end of the weight is fixed to the rotating frame 44, and the other end is fixed to the inner wall of the lower case 1. The end of the transparent light guide plate 42 embedded in the concave semicircle 43 has a concave circular shape facing the LED light board 46, which is used to improve the coupling efficiency of light from the LED light board 46 into the transparent light guide plate 42.

[0029] The working principle of the digital piano with light-guiding keys is as follows:

[0030] When using the device, first place the device in the working area, then connect the external power supply to the lower shell 1 of the piano frame to provide the power required for the device to work; during use, the user turns on and switches the mode of the function key panel 31 by pressing the main board 3, and then presses the light-guiding key 4. At this time, the key body 41 is pressed and rotates and pulls the reset member provided on the rotating frame 44 to conduct. Here, the key body 41 rotates and squeezes the button at its bottom to make the PCB signal board 45 generate an electrical signal and transmit it to the function key panel 31, and the LED light panel 4 is respectively turned on by the function key panel 31. 6 and the speaker component inside it are energized, so that the LED light board 46 is energized to generate light sources of various colors and shine into the interior of the transparent light guide plate 42 through the concave semicircle 43 and the side opening of the transparent light guide plate 42. Here, the light is scattered by the diamond-shaped reflector arranged inside the transparent light guide plate 42, so as to achieve multi-angle and large-scale uniform dispersion of the light source, and form soft and uniform color on the transparent light guide plate 42. The diamond structure arranged on the transparent light guide plate 42 can also avoid the light source intensity being too high and affecting the user's perception; at the same time, the speaker component emits corresponding notes to achieve performance.

[0031] The present invention provides a digital piano with light-guiding keys through improvement. The rotation of the key body 41 pulls the reset member on the rotating frame 44 to conduct on the one hand, and squeezes the bottom button to trigger the PCB signal board 45 to generate an electrical signal to transmit to the function key panel 31. The function key panel 31 first supplies power to the LED light panel 46. The colorful RGB light source generated by it enters the interior of the transparent light guide plate 42 through the concave semicircle 43 and the side opening, and is precisely scattered by its built-in array reflector to form a multi-angle, large-scale, uniform and soft light effect. The diamond structure on the surface of the transparent light guide plate 42 further prevents glare from strong light and optimizes the visual experience; secondly, it synchronously activates the speaker component inside it to emit the corresponding note sound, realizing instant and immersive linkage feedback of the dynamic colors of sound and light every time the user presses the light-guiding key 4.
