Description

Technical Field

[0001] The invention relates to the technical fields of signal transmission, electro-acoustic musical instruments, soft materials and electronic components, and in particular to a light source centralized luminous electronic drum. Background Art

[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 signals by hitting. 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. Although the volume and space occupancy of electronic drums have been significantly improved compared to traditional drum sets, the structure of the rigid bracket makes the current electronic drums still too complicated in structure, and the volume is still large, which is inconvenient to carry and store. In addition, the current electronic drum pads do not support light when hitting, lack a sense of technology, and the user experience is not good.

[0003] To sum up, the existing technical problems include no support for luminescence, complex structure, large size, inconvenient to carry and store, and poor user experience. Summary of the invention

[0004] In view of the deficiencies in the above-mentioned prior art, the present invention provides a light-source centralized luminous electronic drum, so as to realize concentrated light transmission to all silicone drum plates for luminescence, simplify the structure of the electronic drum, reduce the cost of the electronic drum, increase the service life of the electronic drum, and enhance the user experience of the electronic drum.

[0014] Furthermore, in the first row of silicone drum disc groups and the second row of silicone drum disc groups, each drum disc includes a central circle striking portion and an outer ring light-emitting portion; the outer ring light-emitting portion surrounds the central circle striking portion; when the light generated by the multiple LED light sources diffuses from both sides of the strip FPC light strip to the first row of silicone drum disc groups and the second row of silicone drum disc groups, it irradiates the outer ring light-emitting portion to make the outer ring light-emitting portion emit light.

[0015] 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.

[0016] 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.

[0017] Furthermore, the outer ring luminous part is distributed with a laser luminous dot matrix; when the light generated by the multiple LED light sources diffuses to the silicone drum, the laser luminous dot matrix emits light under the irradiation of the light, so that the outer ring luminous part emits light.

[0018] Furthermore, the electronic drum host is cylindrical in shape, and the flexible substrate and the flexible light source board have the same shape; the first row of silicone drum disc groups are located on the rear side of the flexible substrate, and the rear side of the substrate is connected to the electronic drum host, and the second row of silicone drum disc groups are located on the front side of the flexible substrate; the area of ​​the front side of the substrate is larger than the area of ​​the rear side of the substrate; the number of drum discs in the second row of silicone drum disc groups is greater than the number of drum discs in the first row of silicone drum disc groups.

[0038] 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.

[0039] See also Figure 1-Figure 9 The embodiment of the present invention provides a light source centralized light emitting electronic drum, comprising:

[0040] A flexible substrate 1 is fixed to one side of an electronic drum host 2;

[0041] 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;

[0042] A flexible light source board 4 is fixed to the flexible substrate 1 and includes a row of multiple LED light sources 400 arranged along a straight line on a strip FPC light strip 40, and the strip FPC light strip 40 is electrically connected to the electronic drum host 2;

[0043] 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 strip FPC light strip 40 to emit light according to the striking operation signal, and the light diffuses from both sides of the strip FPC light strip 40 to the first row of silicone drum disc groups 30 and the second row of silicone drum disc groups 31, so that the drum discs of the first row of silicone drum disc groups 30 and the second row of silicone drum disc groups 31 emit light.

[0044] It should be noted that, in the present 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 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 centrally arranged on a strip FPC light strip 40 along a straight line and 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 taps any drum disc, the drum disc senses the tapping operation and transmits the 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 tapping signal. The luminous LED light source 400 diffuses light from both sides of the strip FPC light strip 40 to the first row of silicone drum disc groups 30 and the second row of silicone drum disc groups 31, so that the drum discs of the first row and the second row of silicone drum disc groups 31 emit light. The flexible substrate 1 and the flexible light source board 4 can be curled together to facilitate the storage of the silicone drum disc 3 and the electronic drum host 2, saving space, and being easy to carry and store. It should be noted that in this embodiment, a plurality of LED light sources 400 are centrally arranged on the strip FPC light strip 40 along a straight line, which can form a centralized light source design, reduce the complexity of independently setting a light source for each drum disc, and thus simplify the overall structure. It should be noted that the design of independently setting a light source for each drum disc to make the drum disc glow is not only complex in structure, cumbersome in installation process, low in installation efficiency, and high in cost, but also when the drum disc is struck, the physical striking force is easily transmitted to the light source to impact the light source, reducing the service life of the light source, resulting in a reduction in the service life of the electronic drum. In the present embodiment, the multiple LED light sources 400 concentrated on the strip FPC light strip 40 are separated from the silicone drum disc 3 and do not emit light directly on the drum disc. Instead, the emitting LED light sources 400 diffuse light from both sides of the strip 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 transmitted diffused light, they emit light indirectly by the irradiation of the light, thereby effectively avoiding 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 improving the service life of the electronic drum.

[0045] In some preferred embodiments, after the flexible light source board 4 is fixed to the flexible substrate 1, the strip 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 strip 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.

[0046] 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.

[0047] 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 strip 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 strip FPC light strip 40 to emit light according to the striking operation signal.

[0048] 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 striking portion 32 and an outer ring luminous portion 33; the outer ring luminous portion 33 surrounds the central circle striking portion 32; when the light generated by the multiple LED light sources 400 diffuses from both sides of the strip FPC light strip 40 to the first row of silicone drum disc groups 30 and the second row of silicone drum disc groups 31, the outer ring luminous portion 33 is irradiated to make the outer ring luminous portion 33 emit light. It should be noted that in this embodiment, the striking 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 striking 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 strip 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 light-emitting part 33 of each drum disc can obtain stable lighting. It is understandable that when the outer ring light-emitting part 33 emits light, it provides immediate visual feedback, so that the user can intuitively see the response when hitting the drum disc, improving interactivity and entertainment. The uniformly luminous outer ring light-emitting part 33 not only enhances the aesthetics of the device, but also increases the user's pleasure of use. The LED light sources 400 on the strip FPC light strip 40 are arranged in a centralized manner, and the light can be effectively transmitted and diffused to the outer ring light-emitting part 33 of each drum disc, reducing light loss and improving light efficiency utilization. The light is evenly diffused from both sides of the strip FPC light strip 40 to the outer ring light-emitting part 33 of each drum disc, making the brightness of the light-emitting part more uniform and reducing uneven brightness or light spot problems. By using a centralized light source on the strip FPC light strip 40, the complexity of independently setting the light source for each drum disc can be reduced, simplifying the overall structural design. In addition, the LED light sources 400 on the strip FPC light strip 40 are arranged in a centralized manner, which can reduce the number of LED light sources 400 and related circuit designs, reduce manufacturing costs, and also reduce maintenance and replacement costs. In addition, concentrating the light sources on the strip FPC light strip 40 can improve the durability and reliability of the overall equipment, help to centrally manage and protect the LED light sources 400 and related electronic components, and extend the service life of the equipment.

[0049] 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 LED light source 400 on the strip FPC light strip 40, it can generate high-brightness light points, 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, thereby improving the visual effect. The laser dot matrix can diffuse light evenly, avoid uneven brightness or light spot problems, and make the light of the outer ring light-emitting part 33 more uniform and consistent. 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.

[0050] 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.

[0051] In some further preferred embodiments, during the process of the light generated by the multiple LED light sources 400 emitting light 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, so as to not only enhance the shading effect. Among them, the shading coating can be a black matte coating.

[0052] 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 strip FPC light strip 40 is bonded to the light guide plate 410 and the reflective film 411 through a first strip of light-shielding tin foil 5 with adhesive backing, and the vertical light-emitting direction of the multiple LED light sources 400 on the strip FPC light strip 40 is covered by a second strip of light-shielding tin foil 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 diffused from both sides of the strip FPC light strip 40 to the first row of silicone drum disc groups 30 and the second row of silicone drum disc groups 31, so that the drum discs of the first row of silicone drum disc groups 30 and the second row of silicone drum disc groups 31 emit light. 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 first strip of light-shielding tin foil 5 with adhesive backing is bonded to the light guide plate 410 and the reflective film 411 to fix each component and block the light at the same time, playing a bonding and fixing role to ensure that each component is firmly connected. The second strip of light-shielding tin foil 6 with adhesive backing covers the vertical light emission 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 along the horizontal direction of the light guide plate 410 and the reflective film 411, and diffuses from both sides of the strip FPC light strip 40 to the silicone drum 3, which can achieve more uniform light emission. The second strip of light-shielding tin foil 6 with adhesive backing blocks the light in the vertical direction, prevents the light from leaking vertically, and prevents the strong light at the light source position from penetrating the outside of the flexible substrate 1 in the vertical direction, affecting the overall aesthetics of the electronic drum. It can be understood that the light guide plate 410 guides the light to the horizontal propagation path, which can avoid the loss of light 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 is evenly diffused from both sides of the strip FPC light strip 40 to the silicone drum disc 3, ensuring that the drum disc emits light more evenly and uniformly. The light-shielding tin foil effectively controls the light path and reduces the problem of light spots and uneven lighting. The uniform lighting effect can enhance the aesthetics of the electronic drum, allowing users to have a better visual experience during use. The long strip of light-shielding tin foil with adhesive backing not only plays a shading role, but also stabilizes the components, avoids loosening and displacement, and improves the stability and durability of the electronic drum.

[0053] 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 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.
