Description

Technical Field

[0001] This utility model relates to the field of headphone technology, and in particular to a decorative aperture and a headphone. Background Technology

[0002] Currently, the decorative cover lighting effects of headphones on the market are mainly achieved by emitting light through LED light strips inside the headphones and guiding the light through light guides. The visual effect of this lighting is relatively ordinary. The light pattern is consistent with the pattern of the light guide, so this lighting effect only has a planar lighting effect and is not very aesthetically pleasing.

[0003] For example, Chinese patent application number CN202121333434.5 discloses a type of headset with a light guide. Specifically, it discloses that "one earpiece and the second earpiece are further provided with a light guide, a decorative frame, and a decorative plate. The decorative plate is connected to the side of the earpiece shell away from the earcups. The decorative frame is installed between the decorative plate and the earpiece shell. The light guide is snapped into the earpiece shell and located between the decorative frame and the decorative plate. The light guide is used to conduct light from the sound-generating components to the outside of the headset." The visual effect of this lighting is rather ordinary; the light pattern matches the pattern of the light guide, so the lighting effect is only a planar effect and has limited aesthetic appeal.

[0004] For example, Chinese patent application CN202020100306.5 discloses an LED light guide earphone, comprising: an upper shell with a light outlet; an LED light panel with an LED light source; a light guide with a hollowed-out area through which light emitted by the LED light source can pass, the light guide being detachably mounted inside the upper shell at the light outlet, so that the LED light source forms uniform and predetermined shaped emitted light through the hollowed-out area and is projected outward from the light outlet; and a lower shell assembly, one side of which is configured as a sound outlet, and the other side supporting the LED light panel and fastening to the upper shell above the LED light panel. The visual effect of this lighting is rather ordinary; the light pattern matches the pattern of the light guide, so the lighting effect is only planar and lacks aesthetic appeal. Utility Model Content

[0005] In view of this, the present invention addresses the deficiencies of the existing technology, and its main purpose is to provide a decorative aperture that can produce a three-dimensional light effect and is more aesthetically pleasing, thereby overcoming the shortcomings of the existing technology.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] This application provides a decorative aperture, including a decorative inner cover; a first circuit board is disposed on the decorative inner cover.

[0008] The interior of the decorative inner cover is equipped with a light guide ring, a reflective lens, and a semi-transparent reflective lens;

[0009] The decorative outer cover is disposed on the decorative inner cover; the light source on the first circuit board is directed toward the light guide ring.

[0010] Preferably, the interior of the decorative inner cover has a first step; the first circuit board is embedded in the back of the decorative inner cover and presses against the first step; the light guide ring is embedded in the interior of the decorative inner cover and presses against the first step.

[0011] Preferably, the reflective lens is embedded in the light guide ring; the light guide ring has a central portion that extends through it, and a thickened portion is formed on the light guide ring, with a recessed portion provided on the thickened portion; the light source faces the recessed portion.

[0012] Preferably, the interior of the decorative inner cover has a second step; the semi-transparent reflective lens is embedded in the decorative inner cover and presses down the second step.

[0013] Preferably, the inner decorative cover has a mounting edge, and the outer decorative cover has a mounting opening and an inner flange; the mounting edge is inserted into the mounting opening, and the inner flange presses against the semi-transparent reflective lens.

[0014] Preferably, a first fastener connects the inner decorative cover and the first circuit board; a second fastener connects the inner decorative cover and the outer decorative cover.

[0015] Preferably, the light guide ring is one of plexiglass, polycarbonate, polyvinyl chloride, and acrylic.

[0016] Preferably, the decorative outer cover is made of light-transmitting plastic or glass.

[0017] This application provides an earphone, including the aforementioned decorative aperture; a headband, a sliding arm, and a sound-producing unit; the sliding arm is telescopically mounted on the headband; and the sound-producing unit is oscillatingly mounted on the sliding arm.

[0018] Preferably, the inner wall of the sliding arm is provided with a limiting tooth, and the end of the head beam is provided with a spring piece that presses against the limiting tooth; a connecting rod is provided between the sliding arm and the sound generating unit, and the sliding arm and the sound generating unit can swing on the connecting rod.

[0019] This invention has significant advantages and beneficial effects compared to existing technologies. Specifically, as described in the above technical solution, the light emitted from the light source on the first circuit board is transmitted to the semi-transparent reflective lens through the light guide ring. The semi-transparent reflective lens transmits some light while simultaneously reflecting some onto the reflective lens. The reflective lens then reflects the light back to the semi-transparent reflective lens, which again transmits some light while reflecting some onto the reflective lens. This cycle repeats, forming multiple beams of parallel light that enter the human eye. Because these parallel beams undergo different reflections, their transmission distances differ, resulting in images that are not on the same plane in the human eye. During the reflection process, the light intensity gradually decreases, thus creating multiple overlapping, sequentially decreasing brightness halos. The number of halos depends on the light intensity; the higher the brightness of the light source, the more halos are visible. Furthermore, by adjusting the distance between the reflective lens and the semi-transparent reflective lens, the visual distance between the halos can be adjusted, resulting in a more dazzling and aesthetically pleasing visual effect.

[0031] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0032] Example 1

[0033] Please refer to Figures 1 to 4 As shown, it illustrates the specific structure of a preferred embodiment of the present invention, which is a decorative aperture 10.

[0034] With the combined action of the light source 118, light guide ring 130, reflector 115, and semi-transparent reflective lens 116, some light energy is emitted from the semi-transparent reflective lens 116, and some light is reflected from the semi-transparent reflective lens 116 to the reflector 115, and then emitted from the semi-transparent reflective lens 116. As a result, the parallel light rays are not imaged on the same plane in the human eye. During the reflection process, the light intensity gradually decreases. In this way, multiple light rings with successively decreasing brightness and overlapping parallel light rings can be seen in the vision, producing a three-dimensional effect that is more beautiful.

[0035] This application provides a decorative aperture 10, including a decorative inner cover 110; a first circuit board 117 is disposed on the decorative inner cover 110; a light guide ring 130, a reflective lens 115, and a semi-transparent reflective lens 116 are disposed inside the decorative inner cover 110; a decorative outer cover 120 is disposed on the decorative inner cover 110; a light source 118 on the first circuit board 117 shines on the light guide ring 130. The light source 118 is preferably an LED light source 118. The light guide ring 130 is made of light-guiding material and can guide light, allowing the light source 118 to be transmitted in the designed direction. The reflective lens 115, also known as a specular reflective lens, mainly functions to refract and reflect light. The semi-transparent reflective lens 116, also known as a semi-transparent and semi-reflective lens, is a special lens that combines light transmission and reflection functions. It can achieve a certain perspective effect when light passes through, and at the same time, it reflects the environment in front of the mirror when the observer looks at the lens, achieving a unique visual effect. After the first circuit board 117 is powered on, the light source 118 will be lit. Preferably, the interior of the decorative inner cover 110 is provided with a light guide ring 130, a reflective lens 115, and a semi-transparent reflective lens 116 in sequence. In this embodiment, the decorative inner cover 110 and the decorative outer cover 120 are preferably annular.

[0036] Please refer to Figure 2 As shown, the decorative aperture 10 includes a decorative outer cover 120, a semi-transparent reflective lens 116, a reflective lens 115, a light guide ring 130, and a decorative inner cover 110. The reflective lens 115 can be glued to the inner ring of the light guide ring 130, and the outer ring of the light guide ring 130 is glued to the inner cavity of the decorative inner cover 110. The decorative inner cover 110 and the decorative outer cover 120 are fastened together to clamp the semi-transparent reflective lens 116 in the cavity formed by the decorative inner cover 110 and the decorative outer cover 120. The decorative inner cover 110 and the decorative outer cover 120 are then locked together with screws.

[0037] Light effect principle: A decorative inner cover 110 is installed on the first circuit board 117. For the specific light reflection path, please refer to... Figure 4As shown. The light emitted from the light source 118 of the first circuit board 117 is transmitted through the light guide ring 130 to the semi-transparent reflective mirror 116. The semi-transparent reflective mirror 116 transmits some light while reflecting some light to the reflective mirror 115. The reflective mirror 115 then reflects the light back to the semi-transparent reflective mirror 116. The semi-transparent reflective mirror 116, in turn, transmits some light while reflecting some light to the reflective mirror 115. For example, the light rays from plane A140 and plane B141 cycle in this way, forming multiple beams of parallel light that enter the human eye. Because these parallel beams have different numbers of reflections, they travel different distances. As a result, the images of these parallel beams are not on the same plane in the human eye. During the reflection process, the light intensity gradually decreases. Thus, multiple overlapping, parallel apertures with successively decreasing brightness are seen in the vision. The number of apertures depends on the light intensity. The higher the brightness of the light source 118 on the first circuit board 117, the more visible apertures there are. Furthermore, by adjusting the distance between the reflecting lens and the semi-transparent reflective lens 116, the visual distance between the apertures can be adjusted, resulting in a richer effect.

[0038] Please refer to Figure 2 , Figure 3 As shown, a first step 111 is formed inside the decorative inner cover 110; a first circuit board 117 is embedded in the back of the decorative inner cover 110 and presses against the first step 111; the light guide ring 130 is embedded in the decorative inner cover 110 and presses against the first step 111. The first fastener 113 is preferably a screw, which fixes the first circuit board 117 to the decorative inner cover 110 and simultaneously fixes the entire decorative light guide ring 10 to the ear shell 221 of the sound-emitting unit 220.

[0039] Preferably, the reflective lens 115 is embedded in the light guide ring 130; the light guide ring 130 has a central section, and a thickened portion 131 is formed on the light guide ring 130, with a recessed portion 132 provided on the thickened portion 131; the light source 118 faces the recessed portion 132. The central section of the light guide ring 130 allows light to be concentrated in a specific area, ensuring brightness. Light enters from the recessed portion 132 of the thickened portion 131 and then enters the light guide ring 130; this design prevents light leakage and improves brightness.

[0040] Preferably, the interior of the decorative inner cover 110 has a second step 112; the semi-transparent reflective lens 116 is embedded in the decorative inner cover 110 and presses against the second step 112. The decorative inner cover 110 has a mounting edge 119, and the decorative outer cover 120 has a mounting opening 121 and an inner flange 122; the mounting edge 119 is inserted into the mounting opening 121, and the inner flange 122 presses against the semi-transparent reflective lens 116. The semi-transparent reflective lens 116 is embedded in the decorative inner cover 110, the second step 112 supports the edge of the semi-transparent reflective lens 116, the mounting edge 119 is inserted into the mounting opening 121, and the inner flange 122 presses against the semi-transparent reflective lens 116. The second fastener 123 assembles the inner cover 110 and the decorative outer cover 120 together. This installation structure is very simple and assembly is more convenient. Preferably, the second fastener is a screw.

[0041] Preferably, the light guide ring 130 is one of plexiglass, polycarbonate, polyvinyl chloride, and acrylic. In this embodiment, the light guide ring 130 is made of acrylic, which has excellent light guiding properties. The decorative outer cover 120 is made of light-transmitting plastic or glass. In this embodiment, the decorative outer cover 120 is made of light-transmitting plastic. The decorative outer cover 120 can also be printed with patterns or logos, making the decorative light ring 10 more aesthetically pleasing and cool after it emits light.

[0042] Example 2

[0043] This application provides an earphone 20, including the aforementioned decorative aperture 10; a headband 210, a sliding arm 212, and a sound-generating unit 220; the sliding arm 212 is telescopically mounted on the headband 210; the sound-generating unit 220 is oscillatingly mounted on the sliding arm 212. The sound-generating unit 220 includes an ear shell 221, a second circuit board 223 disposed within the ear shell 221, a battery 224, a speaker 225, and other accessories. The ear shell 221 has a mounting groove 222, within which the decorative aperture 10 is fixed. The sliding arm 212 can slide up and down on the headband 210, and the sound-generating unit 220 can oscillate on the sliding arm 212. This design improves wearing comfort and enhances the user experience.

[0044] Preferably, the inner wall of the sliding arm 212 is provided with a limiting tooth 213, and the end of the headband 210 is provided with a spring piece 217, which presses against the limiting tooth 213. A connecting rod 214 is provided between the sliding arm 212 and the sound-generating unit 220, allowing the sliding arm 212 and the sound-generating unit 220 to swing on the connecting rod 214. The spring piece 217 and the limiting tooth 213 cooperate to effectively limit the position of the sliding arm 212 and accommodate more users. A first rotating shaft 215 is provided at the upper end of the connecting rod 214, and a second rotating shaft 216 is provided at the lower end of the connecting rod 214. The first rotating shaft 215 can rotate on the sliding arm 212, and the second rotating shaft 216 can rotate on the ear shell 221. Therefore, the sound-generating unit 220 can swing in and out. This design allows the sound-generating unit 220 to fit the ear, improving comfort. Meanwhile, the ear shell 221 can also rotate on the connecting rod 214, so the sound unit 220 can not only swing in and out, but also rotate, making it more comfortable to wear.

[0045] In summary, the key design feature of this invention lies in the fact that, with the combined effect of the light source 118, light guide ring 130, reflective lens 115, and semi-transparent reflective lens 116, some light energy is emitted from the semi-transparent reflective lens 116, and some light is reflected from the semi-transparent reflective lens 116 to the reflective lens 115, and then emitted again from the semi-transparent reflective lens 116. As a result, the parallel light rays are not projected onto the same plane in the human eye. During the continuous reflection of light, the light intensity gradually decreases, thus creating multiple overlapping, sequentially decreasing brightness rings that appear parallel to each other, producing a three-dimensional effect that is more aesthetically pleasing and visually striking.
