Description

Technical Field

[0001] This disclosure relates to the technical field of headphone ambient lighting, and in particular to a headphone ambient lighting structure and headphones. Background Technology

[0002] In the headphone product field, ambient lighting functionality is gaining increasing attention to enhance user experience and add fun and personalization to products. Traditional headphone ambient lighting structures typically employ a simple light guide design, usually placing a light source inside the headphone shell and using conventional light guide plates or strips to transmit the light to the headphone surface to achieve the ambient lighting effect.

[0003] However, due to the relatively simple structure of conventional light guide plates or strips, the direction of light propagation within them is relatively fixed, making it difficult to achieve sufficient and effective diffusion and reflection of light. This leads to uneven light distribution in headphone ambient lights during practical applications, with some areas experiencing excessively bright light, creating glaring spots, while other areas are too dark. The limitation of the single direction of light propagation within the light guide further affects the uniformity of the ambient light, reducing visual comfort for users. Utility Model Content

[0004] The purpose of this disclosure is to overcome the shortcomings of the prior art and provide an earphone ambient light structure and headphones that improve light emission uniformity.

[0005] The purpose of this disclosure is achieved through the following technical solution: An earphone ambient light structure includes an earphone shell, a light source assembly, and an irregularly shaped reflective assembly. The earphone shell has an ambient light receiving cavity, and the light source assembly is fixed to the earphone shell and housed within the ambient light receiving cavity.

[0006] The light source assembly includes a circuit board and multiple light-emitting elements, all of which are electrically connected to the circuit board. The irregularly shaped reflective assembly includes a base plate, multiple rack reflectors, and multiple fan-shaped reflectors. The base plate covers the earphone shell. The light-emitting surface of each light-emitting element faces one of its rack reflectors, and the light-emitting surface of each rack reflector faces one of its fan-shaped reflectors. The base plate has multiple fan-shaped light guide cavities, and each fan-shaped light guide cavity is correspondingly arranged with one of the fan-shaped reflectors.

[0007] In one embodiment, the rack reflector is provided with a plurality of reflective teeth, which are spaced apart on the rack reflector.

[0008] In one embodiment, the rack reflector is an arc-shaped rack reflector, so that the outline of the rack reflector is adapted to the fan-shaped reflector.

[0009] In one embodiment, the radius of each of the said fan-shaped reflectors is not equal.

[0010] In one embodiment, the fan-shaped reflector has a concave reflective surface.

[0011] In one embodiment, the circuit board has a first fixing hole, and the base plate has a fixing connecting post on the side adjacent to the circuit board. The fixing connecting post has a second fixing hole, and the first fixing hole communicates with the second fixing hole. The first fixing hole and the second fixing hole are used to insert fasteners.

[0012] In one embodiment, the earphone ambient light structure further includes a light-transmitting decorative component, and a snap-fit ​​component is provided on the side of the light-transmitting decorative component adjacent to the base plate. The base plate has a snap-fit ​​through hole, and the snap-fit ​​component snaps into the snap-fit ​​through hole.

[0013] In one embodiment, the earphone shell has a snap-fit ​​groove, and the edge of the base plate snaps into the snap-fit ​​groove.

[0014] In one embodiment, the light-emitting element is composed of multiple LED beads of different colors, so that the light-emitting element can be combined to output light of different colors.

[0015] This application also provides a headset including the headphone ambient light structure described in any embodiment.

[0016] Compared with the prior art, this disclosure has at least the following advantages: The aforementioned earphone ambient light structure employs irregularly shaped reflective components. Both the rack and pinion reflectors and the fan-shaped reflectors are irregularly shaped designs. Light undergoes multiple reflections through the reflective teeth of the rack and pinion reflectors and the fan-shaped reflectors, allowing the light to cover a wider range. This overcomes the defects of uneven light distribution, excessive brightness, or excessive darkness in conventional light guide structures, thereby changing the limitation of the single direction of light propagation in traditional light guides and improving the uniformity of light.

The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of this disclosure. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0022] To better understand the technical solutions and beneficial effects of this disclosure, the following detailed description is provided in conjunction with specific embodiments: like Figures 1 to 6 As shown, an embodiment of the present disclosure of an earphone ambient light structure 10 includes an earphone shell 100, a light source assembly 200 and an irregularly shaped reflective assembly 300. The earphone shell 100 has an ambient light receiving cavity 1001, and the light source assembly 200 is fixed to the earphone shell 100 and housed in the ambient light receiving cavity 1001.

[0023] The light source assembly 200 includes a circuit board 210 and multiple light-emitting elements 220, all of which are electrically connected to the circuit board 210. The irregularly shaped reflective assembly 300 includes a base plate 310, multiple rack reflectors 320, and multiple fan-shaped reflectors 330. The base plate 310 covers the earphone shell 100. The light-emitting surface of each light-emitting element 220 faces one of its rack reflectors 320, and the light-emitting surface of each rack reflector 320 faces one of its fan-shaped reflectors 330. The base plate 310 has multiple fan-shaped light guide cavities 3101, and each fan-shaped light guide cavity 3101 is correspondingly arranged with a fan-shaped reflector 330.

[0024] In this embodiment, when the light source assembly 200 is powered on, multiple light-emitting elements 220 on the circuit board 210 emit light. Specifically, the power output terminal of the circuit board 210 is electrically connected to the light source assembly 200 to supply power to the light source assembly 200, and the light is directly directed towards the corresponding rack and pinion reflector 320. Since the rack and pinion reflector 320 has an irregular shape, its surface is covered with multiple reflective teeth, which exhibit different tilt angles and arrangements. When light shines on the reflective teeth, multiple reflections occur. Light incident at different angles, after being reflected by the reflective teeth, can exit in a more uniform direction, changing the situation where localized over-brightness or under-brightness might occur when light is directly irradiated.

[0025] Furthermore, the light emitted from the rack reflector 320 is directed towards the corresponding fan-shaped reflector 330. The fan-shaped reflector 330 also has an irregularly shaped reflective structure; its curved surface matches the reflective teeth of the rack reflector 320, further reflecting and guiding the dispersed light from the rack reflector 320. After reflection within the fan-shaped reflector 330, the light enters the corresponding fan-shaped light guide cavity 3101 on the base plate 310. The shape of the fan-shaped light guide cavity 3101 is adapted to the fan-shaped reflector 330, constraining and guiding the light, ultimately allowing the light to be uniformly emitted from the fan-shaped light guide cavity 3101, creating the ambient light effect of the headphones.

[0026] The aforementioned earphone ambient light structure 10 employs an irregularly shaped reflective component 300, in which the rack and pinion reflector 320 and the fan-shaped reflector 330 are both irregularly shaped designs. Light is reflected multiple times through the reflective teeth of the rack and pinion reflector 320 and the fan-shaped reflector 330, enabling the light to cover a wider range. This overcomes the defects of uneven light distribution, excessive brightness or darkness in conventional light guide structures, thereby changing the limitation of the single direction of light propagation in traditional light guides and improving the uniformity of light.

[0027] like Figures 4 to 6As shown, in one embodiment, the rack and pinion reflector 320 is provided with multiple reflective teeth 321, which are spaced apart. In this embodiment, when the light emitted by the light-emitting element 220 shines on the rack and pinion reflector 320, each reflective tooth 321 acts as an independent small reflective surface due to the spaced arrangement of the multiple reflective teeth 321. Upon contact with the multiple reflective teeth 321, the light undergoes multiple irregular reflections. The reflective teeth 321 at different positions reflect the light in different directions, dispersing the originally concentrated light beam into numerous tiny light rays. This achieves light scattering over a larger area, resulting in a more uniform distribution of light in space. This avoids situations where local light is too concentrated, forming bright spots, or where local light is insufficient, creating dark areas, thus laying the foundation for a uniform ambient lighting effect.

[0028] like Figures 4 to 6 As shown, in one embodiment, the rack and pinion reflector 320 is an arc-shaped rack and pinion reflector, so that the outline of the rack and pinion reflector 320 is adapted to the fan-shaped reflector 330. In this embodiment, the adaptation of the arc-shaped rack and pinion reflector to the fan-shaped reflector 330 optimizes the light reflection path. Because their outlines fit each other, compared with the straight rack and pinion reflector, the arc-shaped structure can guide the light to be reflected at an angle that better conforms to the curvature of the fan-shaped reflector 330. When the light emitted by the light-emitting element 220 hits the arc-shaped rack and pinion reflector, the reflection of the light on the arc surface is more orderly, allowing the light to enter the interior of the fan-shaped reflector 330 more smoothly. This significantly reduces the loss of light during transmission, and more light can be effectively utilized, thereby significantly improving the luminous efficiency of the ambient light.

[0029] like Figure 4 and Figure 5 As shown, in one embodiment, the radius of each fan-shaped reflector 330 is not equal. In this embodiment, fan-shaped reflectors 330 with different radii can accurately reflect and distribute light in different areas. A larger radius fan-shaped reflector 330 can cover a wider area, propagating light to the edges of the headphone ambient light structure, ensuring that a large area around the headphones is illuminated. A smaller radius fan-shaped reflector 330 can perform fine-tuning of light in localized areas, focusing or further dispersing the light to achieve a more uniform distribution across all areas.

[0030] like Figure 4 and Figure 5As shown, in one embodiment, the fan-shaped reflector 330 has a concave reflective surface 331. In this embodiment, when light emitted from the rack and pinion reflector 320 reaches the concave reflective surface 331 of the fan-shaped reflector 330, some of the light rays converge in a specific direction under the action of the reflective surface, making the light more concentrated during propagation and reducing light scattering and loss. Simultaneously, the concave reflective surface 331 can also reflect light multiple times, further enhancing the light reflection intensity. In situations where the light is relatively weak, the converging and multiple reflections of the concave reflective surface 331 can effectively enhance the light, thereby ensuring that the ambient light presents a bright and clear lighting effect in various environments.

[0031] like Figures 4 to 6 As shown, in one embodiment, the circuit board 210 has a first fixing hole 2101, and the base plate 310 has a fixing connecting post 311 on the side adjacent to the circuit board 210. The fixing connecting post 311 has a second fixing hole 3102, and the first fixing hole 2101 communicates with the second fixing hole 3102. The first fixing hole 2101 and the second fixing hole 3102 are used to pass through fasteners. In this embodiment, through the cooperation of the first fixing hole 2101, the second fixing hole 3102 and the fasteners, the circuit board 210 can be firmly connected to the base plate 310. This stable connection method can effectively prevent the circuit board 210 from shifting or loosening due to external forces, ensuring that the multiple light-emitting elements 220 on the circuit board 210 always maintain an accurate relative positional relationship with the rack and pinion reflector 320, so that the light emitted by the light-emitting elements 220 can stably shine on the rack and pinion reflector 320, ensuring the accuracy of light reflection and propagation path, thereby maintaining the stable and reliable working state of the ambient light, and thus avoiding the deviation of the light propagation path caused by component shaking.

[0032] like Figure 3 and Figure 4 As shown, in one embodiment, the headphone ambient light structure 10 further includes a light-transmitting decorative element 400. A snap-fit ​​element 410 is provided on the side of the light-transmitting decorative element 400 adjacent to the base plate 310. The base plate 310 has a snap-fit ​​through hole 3103, and the snap-fit ​​element 410 snaps into the snap-fit ​​through hole 3103. In this embodiment, the light-transmitting characteristics of the light-transmitting decorative element 400 allow the light emitted from the fan-shaped light guide cavity 3101 after multiple reflections and guidance by the irregularly shaped reflector component 300 to be diffused more softly and evenly. Simultaneously, the light-transmitting decorative element 400 can also prevent dust, debris, etc., from entering the interior of the headphone ambient light structure 10, avoiding damage to the light source component 200 and the irregularly shaped reflector component 300, thereby extending the service life of the entire headphone ambient light structure.

[0033] like Figure 2 and Figure 3As shown, in one embodiment, the earphone shell 100 has a snap-fit ​​groove 1002, and the edge of the base plate 310 snaps into the snap-fit ​​groove 1002. In this embodiment, by snapping the edge of the base plate 310 into the snap-fit ​​groove 1002 of the earphone shell 100, a stable mounting base is provided for the entire earphone ambient light structure 10, effectively preventing the base plate 310 from loosening or falling off, ensuring that the internal structures such as the irregularly shaped reflective component 300 and the light source component 200 are always in the correct position, thereby ensuring that the light can be reflected along a predetermined path, and effectively preventing dust, debris, etc. from entering the earphone ambient light structure 10.

[0034] like Figure 6 As shown, in one embodiment, the light-emitting element 220 is composed of multiple LED beads of different colors, so that the light-emitting element 220 can be combined to output different colors of light. In this embodiment, the light-emitting element 220 uses multiple LED beads of different colors (such as red, green, and blue tri-color LED beads). Through the driving control of the circuit board 210, the light intensity and lighting duration of each color LED bead can be flexibly adjusted to combine and output a variety of light colors. This allows the headphone ambient light to break through the limitation of a single color and present rich color changes according to user needs, usage scenarios, or device status (such as music rhythm, call status, etc.), thereby improving the scene adaptability and visual appeal of the ambient light.

[0035] This application also provides a headset, including an ambient light structure 10 according to any embodiment. In this embodiment, when the light source assembly 200 is powered on, multiple light-emitting elements 220 on the circuit board 210 emit light, which directly hits the corresponding rack and pinion reflector 320. Since the rack and pinion reflector 320 has an irregular shape, its surface is distributed with multiple reflective teeth, which present different tilt angles and arrangements. When light shines on the reflective teeth, multiple reflections occur. Light incident at different angles can be emitted in a more uniform direction after being reflected by the reflective teeth, changing the situation of local over-brightness or under-brightness that may occur when the light is directly irradiated. Furthermore, the light emitted from the rack and pinion reflector 320 hits the corresponding fan-shaped reflector 330. The fan-shaped reflector 330 also has an irregular reflective structure, and its curved surface cooperates with the reflective teeth of the rack and pinion reflector 320 to further reflect and guide the dispersed light transmitted from the rack and pinion reflector 320. After being reflected within the fan-shaped reflector 330, the light enters the corresponding fan-shaped light guide cavity 3101 on the base plate 310. The shape of the fan-shaped light guide cavity 3101 is adapted to the fan-shaped reflector 330, which constrains and guides the light, ultimately enabling the light to be emitted uniformly from the fan-shaped light guide cavity 3101, forming the ambient light effect of the headphones.

[0036] Compared with the prior art, this disclosure has at least the following advantages: The aforementioned earphone ambient light structure 10 employs an irregularly shaped reflective component 300, in which the rack and pinion reflector 320 and the fan-shaped reflector 330 are both irregularly shaped designs. Light is reflected multiple times through the reflective teeth of the rack and pinion reflector 320 and the fan-shaped reflector 330, enabling the light to cover a wider range. This overcomes the defects of uneven light distribution, excessive brightness or darkness in conventional light guide structures, thereby changing the limitation of the single direction of light propagation in traditional light guides and improving the uniformity of light.

[0037] The embodiments described above are merely illustrative of several implementations of this disclosure, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the disclosed patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this disclosure, and these all fall within the protection scope of this disclosure. Therefore, the protection scope of this patent should be determined by the appended claims.
