[0002] Electronic drums are electronic musical instruments that simulate traditional drum sets. They consist of a set of electronic pads, drum sound modules, and other accessories to generate different types of percussion sound effects. Among them, the pads are usually fixed on a rigid bracket, made of rubber or silicone, with a certain degree of elasticity and rebound force on the surface, which can simulate the feel of real drums. Each pad is connected to the drum sound module and generates a signal by hitting it. The drum sound module is the core part of the electronic drum. It contains a variety of preset drum sounds and sound effects. The drum sound module triggers the corresponding sound according to the signal from the pad. Compared with traditional drum sets, electronic drums are lighter, take up less space, and are easy to carry and store. The current electronic drum pads do not support light when struck, lack a sense of technology, and the user experience is not good.

[0014] Furthermore, when the light generated by the multiple LED light sources diffuses to the silicone drum plate to illuminate the center circle striking part, the inner side of the center circle striking part blocks the light to prevent the light from irradiating from the inside of the center circle striking part to the outside of the center circle striking part.

[0015] Furthermore, when the light generated by the multiple LED light sources diffuses to the silicone drum, the inner side of the flexible substrate blocks the light, preventing the light from irradiating from the inside of the flexible substrate to the outside of the flexible substrate.

[0037] In order to enable those skilled in the art to better understand the scheme of the present invention, the technical scheme in the embodiment of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiment of the present invention. Obviously, the described embodiment is only an embodiment of a part of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work should fall within the scope of protection of the present invention.

[0038] See also Figure 1-Figure 9 The embodiment of the present invention provides a light source structure of a light-emitting electronic drum, including a flexible light source board, a sheet FPC light strip, and a plurality of LED light sources. The flexible light source board is fixed to the flexible substrate of the light-emitting electronic drum, and the flexible substrate is provided with a silicone drum disc electrically connected to the electronic drum host of the light-emitting electronic drum; the sheet FPC light strip is installed on the flexible light source board and electrically connected to the electronic drum host; the plurality of LED light sources are dispersed into a plurality of light source groups, and each light source group includes at least two light sources surrounding the periphery of any one of the silicone drum discs; when any of the silicone drum discs receives a user's tapping operation, a tapping operation signal is transmitted to the electronic drum host, and the electronic drum host controls the plurality of LED light sources on the sheet FPC light strip to emit light according to the tapping operation signal, and the light emitted by each of the light source groups diffuses to the drum discs surrounding it, so that the drum discs emit light, thereby realizing that the light source groups emit light to the drum discs respectively, making the electronic drums emit light evenly, and improving the user experience of the electronic drums.

[0039] It should be noted that, in a specific embodiment, the flexible substrate 1 is fixed to one side of the electronic drum host 2; the silicone drum disc 3 includes a first row of silicone drum disc groups 30 and a second row of silicone drum disc groups 31, which are arranged on the flexible substrate 1 and electrically connected to the electronic drum host 2; the flexible light source board 4 is fixed to the flexible substrate 1 and is located between the first row of silicone drum disc groups 30 and the second row of silicone drum disc groups 31, including a plurality of LED light sources 400 dispersed on a sheet FPC light strip 40, the plurality of LED light sources 400 are dispersed into a plurality of light source groups, each light source group includes at least two light sources surrounding the periphery of any one of the silicone drum discs, and the sheet FPC light strip 40 is electrically connected to the electronic drum host 2;

[0040] When the flexible substrate 1 is rolled up, it drives the flexible light source board 4 to roll up, and stores the silicone drum discs 3 and the electronic drum host 2; when any of the silicone drum discs 3 is struck by a user, a striking operation signal is transmitted to the electronic drum host 2, and the electronic drum host 2 controls the multiple LED light sources 400 on the sheet FPC light strip 40 to emit light according to the striking operation signal, and the light emitted by each light source group diffuses toward the drum discs surrounding it, so that the drum discs emit light.

[0041] It should be noted that, in this embodiment, the flexible substrate 1 is fixed to the electronic drum host 2, providing support for the silicone drum disc 3 and a flexible curling function. The flexible substrate 1 and the flexible light source board 4 can be curled together, which is convenient for storing the silicone drum disc 3 and the electronic drum host 2, saving space, and is easy to carry and store. The silicone drum disc 3 is divided into a first row of silicone drum disc groups 30 and a second row of silicone drum disc groups 31. The first row of silicone drum disc groups 30 and the second row of silicone drum disc groups 31 are arranged on the flexible substrate 1, which can accept user tapping operations and transmit signals to the electronic drum host 2. The flexible light source board 4 includes a plurality of LED light sources 400, and the plurality of LED light sources 400 are dispersed on the sheet FPC light strip 40. The plurality of LED light sources 400 are divided into a plurality of independent light source groups, each light source group includes at least two light sources surrounding the periphery of any one of the silicone drum discs 3, and the sheet FPC light strip 40 is electrically connected to the electronic drum host 2. The electronic drum host 2 processes the tapping operation signal and controls the LED light source 400 to emit light. When the user strikes any drum plate, the drum plate senses the striking operation and transmits a signal to the electronic drum host 2. The electronic drum host 2 controls the LED light source 400 on the flexible light source board 4 to emit light according to the received striking signal, and the light emitted by each light source group spreads to the drum plate around it, making the drum plate emit light, greatly improving the uniformity of the light emission of the drum plate.

[0042] It should be noted that if multiple LED light sources 400 are arranged in a row along a straight line, although light can also be transmitted from both sides of the row of LED light sources 400 to the first row of silicone drum disc groups and the second row of silicone drum disc groups to illuminate the drum discs, due to the difference in distance and position between each drum disc and each LED light source 400, the drum discs will not emit light uniformly, and may even produce light spots, affecting the visual beauty of the electronic drum. In this embodiment, the flexible light source board 4 includes multiple LED light sources 400, and the multiple LED light sources 400 are dispersed on the sheet FPC light strip 40. The multiple LED light sources 400 are divided into multiple independent light source groups, each light source group includes at least two light sources surrounding the periphery of any one of the silicone drum discs 3, and the light emitted by each of the light source groups diffuses to the drum discs it surrounds, irradiating the drum discs to make the drum discs emit light indirectly, so that each drum disc has an independent light source group to provide light, effectively enhancing the uniformity of light emission of the electronic drum. In addition, in the present embodiment, the multiple LED light sources 400 dispersed on the sheet FPC light strip 40 are separated from the silicone drum disc 3 and do not emit light directly on the drum disc. Instead, the light emitted by each of the light source groups diffuses toward the drum disc surrounding it, illuminating the drum disc and causing it to emit light indirectly. This effectively avoids the problem of the drum disc being susceptible to knocking and impact in the design in which each drum disc is independently provided with a light source to emit light directly, thereby increasing the service life of the electronic drum.

[0043] In some preferred embodiments, after the flexible light source board 4 is fixed to the flexible substrate 1, the sheet FPC light strip 40 is located in the middle of the first row of silicone drum disc groups 30 and the second row of silicone drum disc groups 31, so that the luminous LED light source 400 diffuses light from both sides of the sheet FPC light strip 40 to the first row of silicone drum disc groups 30 and the second row of silicone drum disc groups 31. After the drum discs of the first and second rows of silicone drum disc groups 31 receive the light transmitted and diffused, they are indirectly illuminated by the irradiation of the light, and the light emission is more uniform. It can be understood that in this embodiment, the design of the flexible substrate 1 and the flexible light source board 4 allows the electronic drum to be curled and stored, thereby reducing the occupied space and improving portability. The use of a centralized light source can reduce the number of LED light sources 400 and related circuit designs, and reduce production costs. The simplified structural design can also reduce assembly and maintenance costs. The design of the centralized light source reduces the impact of the LED light source 400 set on a single independent drum disc, thereby improving the overall service life. When the user strikes the drum disc, the light of the drum disc improves the visual effect and user experience.

[0044] In some preferred embodiments, the flexible substrate 1 includes a substrate upper skin 10 and a substrate lower skin 11; the substrate upper skin 10 is located above the substrate lower skin 11 and connected to the substrate lower skin 11; the silicone drum disc 3 is arranged on the substrate upper skin 10, and the flexible light source board 4 is assembled between the substrate upper skin 10 and the substrate lower skin 11. It should be noted that the space between the substrate upper skin 10 and the substrate lower skin 11 can be used to install the flexible light source board 4 to ensure that the light source board will not be damaged when curled. Clamping the flexible light source board 4 between the substrate upper skin 10 and the substrate lower skin 11 can provide better protection, avoid damage to the light source board by external impact and friction, and increase the service life of the light source board. It also helps to evenly diffuse the light, so that the luminous effect of the silicone drum disc 3 is more consistent, improving the user's visual experience. At the same time, the design of the upper and lower skins of the substrate can increase the structural stability of the entire electronic drum, and the internal components can remain stable even during frequent use and movement. The flexible substrate 1 can be made of any one of polyimide, polyester, thermoplastic polyurethane, polyurethane, and polyethylene terephthalate.

[0045] In some preferred embodiments, the electronic drum host 2 includes a housing 20, a main PCB board 21 and a speaker 22; the speaker 22 and the main PCB board 21 are assembled in the housing 20, and the main PCB board 21 is electrically connected to the speaker 22; the flexible substrate 1 is fixed to one side of the housing 20. The flexible light source board 4 includes a light source board body 41, the light source board body 41 is fixed to the flexible substrate 1, and the sheet FPC light strip 40 is arranged on the light source board body 41. When any of the silicone drum plates 3 is struck by a user, a striking operation signal is transmitted to the main PCB board 21 of the electronic drum host 2, and the main PCB board 21 controls the multiple LED light sources 400 on the sheet FPC light strip 40 to emit light according to the striking operation signal.

[0046] In some preferred embodiments, each drum disc in the first row of silicone drum disc groups 30 and the second row of silicone drum disc groups 31 includes a central circle knocking portion 32 and an outer ring luminous portion 33; the outer ring luminous portion 33 surrounds the central circle knocking portion 32; when the light emitted by each of the light source groups diffuses to the drum disc it surrounds, it irradiates the outer ring luminous portion to make the outer ring luminous portion emit light. It should be noted that in this embodiment, the knocking part and the luminous part of the drum disc are separated so that each function can work independently without interfering with each other. The outer ring luminous portion 33 surrounds the central circle knocking portion 32 to ensure that the luminous portion evenly covers the edge area of ​​the entire drum disc and provides a good visual effect. The light is transmitted from the sheet FPC light strip 40 to the outer ring luminous portion 33 of the drum disc, which can ensure that the outer ring luminous portion 33 obtains sufficient light, thereby achieving uniform light emission. This design can effectively utilize the light effect of the LED light source 400, so that the outer ring luminous portion 33 of each drum disc can obtain stable light. It is understandable that when the outer ring light-emitting portion 33 emits light, it provides immediate visual feedback, allowing the user to intuitively see the response when hitting the drum disc, thereby improving interactivity and entertainment. The uniformly luminous outer ring light-emitting portion 33 not only enhances the aesthetics of the device, but also increases the user's pleasure of use. The light emitted by each of the light source groups diffuses toward the drum disc it surrounds, and the light can be effectively transmitted and diffused to the outer ring light-emitting portion 33 of the drum disc, reducing light loss and improving light efficiency utilization. The light diffuses from the light source group to the outer ring light-emitting portion 33 of each drum disc, making the brightness of the light-emitting portion more uniform, which can avoid uneven brightness or light spot problems.

[0047] In some further preferred embodiments, the outer ring light-emitting part 33 is distributed with a laser light-emitting dot matrix 330; when the light generated by the multiple LED light sources 400 is diffused to the silicone drum 3, the laser light-emitting dot matrix 330 emits light under the irradiation of the light, so that the outer ring light-emitting part 33 emits light. It should be noted that the laser light-emitting dot matrix 330 is a light point cluster that can produce high brightness and high contrast in a smaller area, thereby improving the luminous effect. This design helps to evenly diffuse the light, making the entire outer ring light-emitting part 33 emit more uniform and bright light. At the same time, the laser dot matrix can gather and reflect the light of the light source, enhance the utilization rate of the light, and reduce light loss. The dot matrix structure can effectively disperse the light, so that each area of ​​the outer ring light-emitting part 33 can obtain sufficient light. It should be noted that after the laser light-emitting dot matrix 330 receives the light transmitted by the light source group on the sheet FPC light strip 40, it can generate high-brightness light spots, which can compensate for the light brightness loss of the LED light source 400, making the outer ring light-emitting part 33 brighter and more eye-catching under the light, and improving the visual effect. The laser dot matrix can diffuse light evenly, avoid uneven brightness or light spot problems, and make the outer ring light-emitting part 33 emit light evenly and consistently. The laser dot matrix can more effectively utilize the light of the LED light source 400, reduce light loss, improve light efficiency utilization, and enhance the light-emitting effect. Through more efficient light utilization, better light-emitting effects can be achieved without increasing the number of LED light sources 400, thereby achieving energy saving. The laser dot matrix light-emitting effect is more dazzling, which can increase the visual appeal of the device and enable users to have a better experience during use. The instant light-emitting feedback of the outer ring light-emitting part 33 when the user taps can enhance the user's interactivity and sense of participation, and improve the entertainment of the product.

[0048] In some further preferred embodiments, when the light generated by the multiple LED light sources 400 is diffused to the silicone drum 3 to illuminate the central circle knocking part 32, the inner side of the central circle knocking part 32 blocks the light, preventing the light from the inside of the central circle knocking part 32 from irradiating the outside of the central circle knocking part 32. It should be noted that the central circle knocking part 32 is mainly used to sense the user's knocking operation. After blocking the light, the light effect of the outer ring luminous part 33 is more prominent and concentrated, which enhances the visual effect. The central circle knocking part 32 does not emit light, which forms a sharp contrast with the outer ring luminous part 33, enhancing the visual impact. In some preferred embodiments, an opaque layer is provided on the inner side of the central circle knocking part 32 to block the light from passing through. The opaque coating has good light-shielding properties while maintaining softness to ensure the sensitivity of the knocking induction. Further, the opaque layer is a multi-layer light-shielding film or a light-shielding coating, which not only enhances the light-shielding effect, but also improves the durability and stability of the knocking part. Among them, the light-shielding coating can adopt a black matte coating.

[0049] In some further preferred embodiments, during the process of the light generated by the light source group emitting light and diffusing to the silicone drum disc 3, the inner side of the flexible substrate 1 blocks the light to prevent the light from irradiating from the inside of the flexible substrate 1 to the outside of the flexible substrate 1. It should be noted that the leakage of light from the inside of the flexible substrate 1 to the outside will affect the beauty of the electronic drum. Blocking the light can ensure that the light is concentrated in the required area, which can improve the utilization rate of light efficiency, make the electronic drum more concentrated and beautiful when in use, avoid the influence of stray light, enhance the overall aesthetics of the electronic drum, and make the visual effect more prominent and attractive. In some preferred embodiments, an opaque layer is provided on the inner side of the flexible substrate 1 to block the light from passing through. Further, the opaque layer is a multi-layer shading film or a shading coating, which not only enhances the shading effect. Among them, the shading coating can be a black matte coating.

[0050] In some improved embodiments, the light source panel body 41 includes a light guide plate 410 and a reflective film 411; the light guide plate 410 and the reflective film 411 are bonded, and the sheet FPC light strip 40 is bonded to the light guide plate 410 and the reflective film 411 through a fixing member, for example, a sheet tin foil 5 with adhesive backing, and the vertical light emission direction of the multiple LED light sources 400 on the sheet FPC light strip 40 is covered by multiple independent light shielding members, for example, multiple independent light shielding foils 6 with adhesive backing, so that the light of the multiple LED light sources 400 is transmitted along the horizontal direction of the light guide plate 410 and the reflective film 411, and the light emitted by each light source group is diffused toward the drum disk surrounding it, so that the drum disk emits light. Among them, the multiple independent light shielding members are arranged in the vertical light emission direction of the multiple LED light sources on the sheet FPC light strip. It should be noted that in this embodiment, the light guide plate 410 can guide the light emitted by the LED light source 400 to be transmitted in the horizontal direction to ensure uniform diffusion of the light. The reflective film 411 can reflect light, improve the utilization rate of light efficiency, and reduce light loss. By combining the light guide plate 410 and the reflective film 411, the light can be evenly diffused in the horizontal direction, reducing light loss and improving the utilization efficiency of the LED light source 400. In addition, the light guide plate 410 and the reflective film 411 are fixed with a sheet of adhesive foil 5 to fix each component, play a bonding and fixing role, and ensure that each component is firmly connected. Multiple pieces of independent light-shielding foil 6 with adhesive foil cover the vertical light-emitting direction of the LED light source 400, which can prevent vertical leakage of light, ensure horizontal propagation of light, concentrate light on the horizontal propagation path, and improve light efficiency utilization. Moreover, more light is transmitted in the horizontal direction of the light guide plate 410 and the reflective film 411, and diffused from the light source group to the drum disc, which can achieve more uniform light emission. Multiple pieces of independent light-shielding foil 6 with adhesive foil shield the light in the vertical direction, prevent vertical leakage of light, and prevent the strong light at the position of the LED light source 400 from passing through the outside of the flexible substrate 1 in the vertical direction, affecting the overall aesthetics of the electronic drum. It is understandable that the light guide plate 410 guides the light to the horizontal propagation path, which can avoid the light loss in the vertical direction. The reflective film 411 reflects the light, further improving the light efficiency utilization rate, so that the light of the LED light source 400 is fully utilized. Under the guidance of the light guide plate 410 and the reflective film 411, the light diffuses from the light source group to the drum plate, ensuring that the drum plate emits light more uniformly. The shading tin foil effectively controls the light path to avoid light spots and uneven lighting problems. The uniform lighting effect can enhance the aesthetics of the electronic drum, allowing users to have a better visual experience during use.

[0051] Furthermore, the electronic drum host 2 is cylindrical in shape, and the flexible substrate 1 and the flexible light source board 4 have the same shape; the first row of silicone drum discs 30 is located on the rear side 13 of the substrate of the flexible substrate 1, and the rear side 13 of the substrate is connected to the electronic drum host 2, and the second row of silicone drum discs 31 is located on the front side 12 of the substrate of the flexible substrate 1; the area of ​​the front side 12 of the substrate is larger than the area of ​​the rear side 13 of the substrate; the number of drum discs in the second row of silicone drum discs 31 is greater than the number of drum discs in the first row of silicone drum discs 30. It should be noted that, in this embodiment, the cylindrical electronic drum host 2 is convenient for winding the substrate, conforms to the flexible characteristics of the flexible substrate 1 and the light source board, and is easy to store and carry. In addition, the front side area of ​​the flexible substrate 1 is larger than the rear side area, so that the front side can accommodate more drum discs, thereby improving the flexibility of use. The second row of silicone drum discs 31 is located on the front side of the flexible substrate 1. The number of drum discs is greater than that of the first row of silicone drum discs 30, making it more convenient to store the electronic drum. After storage, the front side of the flexible substrate 1 can completely cover the electronic drum host 2, making the storage structure of the electronic drum more compact and enhancing portability.
