Detailed Description

The following description of the technical solutions in the embodiments of the present application will be made clearly and completely with reference to the accompanying drawings in the embodiments of the present application, and it is apparent that the described embodiments are only some embodiments of the present application, not all embodiments. All other embodiments, which can be made by one of ordinary skill in the art without undue burden from the present disclosure, are within the scope of the present disclosure.

The present inventors have long studied and found that in the related art, a light emitting module is often designed to have various appearances (e.g., cartoon pattern, geometric pattern, etc.) to increase the visual effect of the earphone. However, this also results in that the visual effect of the light emitting module 200 of the headset 1 is largely limited by the physical structure of the light emitting module, and the light emitting effect is monotonous for the user, so that it is difficult to obtain unexpected effects. In order to solve the above technical problems, the present application proposes the following embodiments.

The headset 1 is an electronic device that can play audio. Referring to fig. 1, the headset 1 may include a headset body 100 and a light emitting module 200. The light emitting module 200 may be disposed on the earphone body 100. When the light emitting module 200 emits light, the headset 1 may be provided with a cool appearance or visual effect. Taking the headphone 1 as an example, the headphone body 100 mainly includes a headband 110 and an earmuff 120, and a speaker (not shown in the drawings) for converting an electric signal into an audio signal output, which is not further limited herein. The speaker is disposed inside the earmuff 120. The number of the earshells 120 may be two, and two ends of the headband 110 are connected to the two earshells 120 in a one-to-one correspondence.

The light emitting module 200 may be provided on the earmuff 120, but may be provided on the headband 110, and is not particularly limited. Referring to fig. 1, the light emitting module 200 is disposed on the earshell 120. As for the manner in which the light emitting module 200 is disposed in the earmuff 120, there are various ways, for example, in some examples, a mounting cavity 121 with one side opened is formed on the earmuff 120, and the light emitting module 200 may be accommodated in the mounting cavity 121. In other embodiments, the light module 200 may also be mounted on the outer wall of the earshell 120. The light emitting module 200 can make the earphone 1 generate a cool and dazzling light emitting effect when the user wears the earshell 120.

The light emitting module 200 will be described in detail below.

Referring to fig. 2 and 3, in some examples, the light emitting module 200 may include: the light source assembly 210, the first optical unit 220, and the second optical unit 230. Wherein, the light source assembly 210 may emit light to form a light effect pattern. The first optical unit 220 may be disposed at one side of the light source assembly 210. The second optical unit 230 may be disposed at the other side of the light source assembly 210 facing away from the first optical unit 220. The first optical unit 220 is at least partially light-transmitting so that a user can observe the light effect pattern through the first optical unit 220. The second optical unit 230 may function to reflect light so that a user can observe the light effect pattern and the mirror image of the light effect pattern through the first optical unit 220. Furthermore, for convenience of subsequent presentation of the light emitting module 200 from different viewing angles, a spatial rectangular coordinate system is introduced here in fig. 2 to exemplarily characterize its orientation.

Since the light effect pattern is a pattern formed by light rays observed by a user, different viewing angles may cause a change in the light effect pattern, the light effect pattern referred to in the present application serves only for convenience of description and should not be construed as a limitation of the light emitting module 200.

Unlike the related art, when the light source assembly 210 emits light, the user can observe the light effect pattern formed by the light emitted from the light source assembly 210 and the mirror image of the light effect pattern through the first optical unit 220, so that the user can observe the pattern with more stereoscopic and layering effects. In addition, the use of the second optical unit 230 to generate a mirror image of the light effect pattern may enhance the visual effect of the light emitting module 200 of a limited volume.

In some examples, the first optical unit 220 may also be used to reflect light emitted by the light source assembly 210 while allowing light to pass through. In this case, since the light effect pattern may be repeatedly reflected between the first optical unit 220 and the second optical unit 230 to generate a mirror image and a mirror image (the mirror image and the mirror image are generally mirror images for convenience of description hereinafter). Thereby, the visual effect of the light emitting module 200 can be made more stereoscopic and hierarchical (see fig. 4).

In some casesIn an example, the first optical unit 220 may be a partially light-transmissive and partially reflective mirror, and the second optical unit 230 may be a reflective and opaque mirror. Specifically, in some examples, the first optical unit 220 may have a first mirror surface facing the reflective cavity 213, and the first mirror surface may have a semi-transmissive effect. The second optical unit 230 may have a second mirror surface facing the reflective cavity 213 _， The second mirror may be a reflective mirror. In this case, the light emitted from the light source assembly 210 may be repeatedly reflected by the first and second mirrors.

In some examples, the first mirror surface may be formed on the first optical unit 220 by polishing or plating an optical film, and the second mirror surface may be formed on the second optical unit 230, and the preparation methods of the first mirror surface and the second mirror surface are not limited herein. In some examples, the first optical unit 220 and the second optical unit 230 may be integrally formed, without any limitation herein.

Referring to fig. 3, 5, 6, and 7, in some examples, the light source assembly 210 may include a light source 211 and a light guide 212 for guiding light _， The light guide 212 has a first sidewall 2121 surrounding the reflective cavity 213, and a partial region of the first sidewall 2121 allows light emitted from the light source 211 to penetrate into the reflective cavity 213.

As for the structure of the light guide 212, there are various structures, for example, the light guide 212 may be a light guide cover, a light guide plate, a light guide sleeve, a light guide sheet, or the like, and is not particularly limited. That is, the light guide 212 may have any shape such as a ring shape, a plate shape, a cover shape, a plate shape, etc., which may be enclosed in the reflective cavity 213, and have an equivalent technical effect. Of course, the light guide 212 may be of an integrally formed structure, or may be split-spliced, or may be arranged separately at intervals (i.e. may include a plurality of light guide sections arranged at intervals, and may enclose the reflective cavity 213).

For example, in one embodiment, the light guide 212 has a receiving cavity 2124, and the light source 211 is disposed within the receiving cavity 2124. Further, the light guide 212 has a first side wall 2121 and a second side wall 2123 opposite to the first side wall 2121, and a receiving cavity 2124 is formed between the first side wall 2121 and the second side wall 2123. In other examples, the first and second sidewalls 2121, 2123 may also be referred to as inner and outer sidewalls of the light guide 212.

The first optical unit 220 is disposed at one side of the light source assembly 210 and covers the reflective cavity 213. The second optical unit 230 is disposed on the other side of the light source assembly 210 facing away from the first optical unit 220, and covers the reflective cavity 213. Wherein at least a portion of the first sidewall 2121 allows light to pass through. Specifically, the first optical unit 220 is disposed on one side of the light guide 212, and the second optical unit 230 is disposed on the other side of the light guide 212 facing away from the first optical unit 220.

The reflective cavity 213 may refer to a chamber for multiple reflections of light. The first side wall 2121 of the light guide 212 at least partially allows light to pass through, the second optical unit 230 is configured to reflect light within the reflective cavity 213, and the first optical unit 220 allows light within the reflective cavity 213 to pass through. Light from the light source 211 can propagate through the light guide 212 toward the reflective cavity 213. Further, the light emitted from the light source 211 can penetrate through the first sidewall 2121 of the light guide 212 and be transmitted into the reflective cavity 213, and then penetrate through the first optical unit 220 after being reflected by the first mirror and the second mirror, so as to generate a cool and dazzling light emitting effect.

In some examples, light guide 212 may be a light guide. Specifically, the light guide 212 further includes a top wall 2122, the top wall 2122 connects the first side wall 2121 and the second side wall 2123, the top wall 2122, the first side wall 2121 and the second side wall 2123 together enclose a receiving cavity 2124, and the receiving cavity 2124 is a groove-shaped structure with an opening at one side. In some examples, the top wall 2122 is disposed proximate to the first optical unit 220.

At least a portion of the first side wall 2121 of the light guide 212 is light transmissive, that is, a portion of the light guide 212 is light transmissive and another portion is light opaque. In some examples, the first side wall 2121 of the light guide 212 is provided with a light-transmitting portion 2125 and a light-shielding portion 2126. Note that the light shielding portion 2126 does not allow light to pass through, i.e., is an opaque portion. There are various shapes and arrangements of the light-transmitting portion 2125 and the light-shielding portion 2126, for example, the light-transmitting portion 2125 and the light-shielding portion 2126 may be arranged along the axial direction of the light guide 212. The light-transmitting portion 2125 and the light-shielding portion 2126 may have annular structures, and as the light-transmitting portion 2125 and the light-shielding portion 2126 have annular structures, a multi-turn light effect can be achieved. Of course, the light-transmitting portion 2125 and the light-shielding portion 2126 may have other shapes, and are not particularly limited herein.

The light transmitting portion 2125 and the light shielding portion 2126 will be exemplified as annular shapes. The annular shape can be annular in a broad sense, can be an overall annular structure, and can also be an annular structure formed by multiple sections of spaced arrangement.

In some examples, the light-transmitting portion 2125 and the light-shielding portion 2126 are both one, the light-transmitting portion 2125 is disposed close to the first optical unit 220, and the light-shielding portion 2126 is disposed close to the second optical unit 230.

In some examples, the light-transmitting portion 2125 and the light-shielding portion 2126 are plural, and the plural light-transmitting portions 2125 and the plural light-shielding portions 2126 are arranged at intervals along the axial direction of the light guide 212. In some examples, there is one light-transmitting portion 2125 and two light-shielding portions 2126, and the light-transmitting portion 2125 is located between the two light-shielding portions 2126. In some examples, the number of light shielding portions 2126 is one, the number of light transmitting portions 2125 is two, and the light shielding portions 2126 are located between the two light transmitting portions 2125. In some examples, the light-transmitting portion 2125 and the light-shielding portion 2126 are plural, and the plural light-transmitting portions 2125 are arranged at intervals from the plural light-shielding portions 2126.

Wherein the light shielding portion 2126 may be formed of a first light shielding member 2126a provided on the first side wall 2121 of the light guide 212. The first light-shielding member 2126a may be a light-shielding paint layer applied to the first side wall 2121, or may be light-shielding foam (black foam) provided inside the first side wall 2121.

In some examples, a portion of the second side wall 2123 is covered with the second light shielding member 215, and a light-permeable portion of the second side wall 2123 that does not cover the second light shielding member 215 is disposed annularly around the circumference of the light guide 212 to allow light within the accommodating cavity 2124 to be able to exit through the light-permeable portion of the second side wall 2123 in a direction away from the reflective cavity 213. In this case, the light emitted from the light source 211 can also be transmitted to the outside through the light-permeable portion of the second side wall 2123, improving the visual effect of the headset 1.

Further, the light source assembly 210 further includes a light plate 214, and the light plate 214 is disposed in the accommodating cavity 2124. The light plate 214 may be annular, and the light sources 211 are plural and are disposed at a side of the light plate 214 facing the top wall 2122 along a circumferential direction of the light plate 214.

In other examples, the light guide 212 may also be provided in a plate shape. The light source 211 is disposed on a side of the light guide 212 facing away from the reflective cavity 213, such that the light guide 212 separates the light source 211 from the reflective cavity 213. In other words, in other examples, the light guide 212 may have only the first sidewall 2121 having a plate shape. The light guide 212 may also function to transmit light and enclose a reflective cavity 213.

In some examples, the first optical unit 220 includes a first transparent body 221, a first optical film layer 222, and a second optical film layer 223. The first optical film layer 222 is disposed on a side of the first transparent body 221 near the reflective cavity 213 to form a first mirror surface. The second optical film 223 is disposed on a side of the first transparent body 221 facing away from the reflective cavity 213, and allows the light transmitted through the first mirror surface to pass through at least partially.

The second optical unit 230 includes a second transparent body 231, a third optical film 232 and a fourth optical film 233, where the third optical film 232 is disposed on a side of the second transparent body 231 near the reflective cavity 213 to form a second mirror. The fourth optical film 233 is disposed on a side of the second transparent body 231 facing away from the reflective cavity 213 to form a third mirror for reflecting light toward the reflective cavity 213, and the fourth optical film 233 is opaque.

In some examples, a side of the second optical unit 230 facing the first optical unit 220 is provided with a fixing groove 234 (shown in fig. 3) for fixing the light source assembly 210. Specifically, the number of the fixing grooves 234 may be two, and they may be annularly and coaxially arranged. One end of the first side wall 2121 and one end of the second side wall 2123, which are close to the second optical unit 230, are embedded in the two fixing grooves 234 in a one-to-one correspondence manner.

In some examples, the light source assembly 210 further includes a light homogenizing element for homogenizing the light emitted by the light source 211. The light equalizing element may be disposed at a side of the first sidewall 2121 facing the receiving chamber 2124. In some examples, the light homogenizing element may be a light homogenizing paper. Specifically, the light equalizing paper may be adhered to the inner surface of the first sidewall 2121. Alternatively, the light balancing paper may be sandwiched between the light plate 214 and the first sidewall 2121.

The shape and structure of the light guide 212 will be described in detail.

Referring to fig. 8a, in some examples, the light guide 212 may be provided in a closed loop. Wherein the light guide 212 is arranged in a closed loop, which means that the light guide 212 is connected end to end, so that the light guide 212 can completely enclose the reflective cavity 213. It should be noted that the light guide 212 is disposed in a closed loop shape, which refers to a closed loop structure in a broad sense, such as, but not limited to, a circular ring, an elliptical ring, a semicircular ring, a square ring, a racetrack ring, a peach-heart ring, or other shaped rings.

Referring to fig. 8b, the light guide 212 may also be disposed in an open loop shape. The light guide 212 is disposed in an open loop, which means that the light guide 212 is not connected end to end, so that the light guide 212 surrounds a portion of the outer circumference of the reflective cavity 213.

Correspondingly, the light-transmitting portion 2125 and the light-shielding portion 2126 are provided in a closed-loop or open-loop manner, respectively. In this case, it may be used to generate end-to-end light effect patterns or end-to-end non-connected light effect patterns, respectively. In addition, for convenience of description, the light guide 212 in fig. 8a and 8b has a ring shape or a "C" shape, but this does not mean that the closed-ring light guide 212 must have a ring shape, and the open-ring light guide 212 must also have a "C" shape. That is, there is no limitation in the shape of the light guide 212, and the shape of the light guide 212 may be any shape (to be described later as some examples).

In some examples, a portion of the earshell 120 may also be made light transmissive in order to achieve a more cool lighting effect. That is, the earmuff 120 includes an opaque portion and a light-transmitting portion, wherein the light-transmitting portion may be provided in a ring shape. By setting the part of the earmuff 120 to be a light-transmitting part, the light emitted by the light-emitting module 200 installed in the earmuff 120 can be transmitted out through the light-transmitting part, so that the outer Zhou Chansheng ring-shaped light effect of the earmuff 120 is achieved, and a more cool light-emitting effect is generated. Taking the mounting cavity 121 with an opening at one side formed on the ear shell 120 as an example, the light emitting module 200 can be accommodated in the mounting cavity 121, and the side wall of the mounting cavity 121 surrounded by the ear shell 120 is provided with the opaque portion and the transparent portion, so that light can be transmitted out through the transparent portion of the ear shell 120 when the light emitting module 200 emits light in the mounting cavity 121. For example, the outer wall of the earshell 120 is convexly provided with an annular convex wall (not shown), which encloses the mounting cavity 121. The annular convex wall has the above-mentioned light-transmitting portion and light-impermeable portion.

For convenience of description, the above embodiments exemplarily explain the specific structure of the light emitting module 200 using the circular ring based on the light effect pattern as an example. However, the light effect pattern may have other shapes for better visual effect.

In particular, the light effect pattern may be continuous, e.g. forming a continuous loop. In other examples, referring to fig. 9, the light effect pattern may also be intermittent, such as forming intermittent rings. Specifically, the first side wall 2121 may be provided with a light-transmitting portion 2125 and a light-shielding portion 2127. The light transmitting portions 2125 and the light shielding portions 2127 are arranged at intervals along the extending direction of the light guide 212. Specifically, the light-transmitting portion 2125 and the light-shielding portion 2127 are each plural. The plurality of light transmitting portions 2125 and the plurality of light shielding portions 2127 are arranged at intervals. In this case, the light effect pattern passing through the light guide 212 into the reflective cavity 213 is not continuous. Correspondingly, the light guide 212 is disposed in a closed loop or an open loop, and the light transmitting portion 2125 and the light shielding portion 2127 are connected to each other to form a closed loop or an open loop.

In this case, if the light shielding part 2127 is not disposed, the light effect pattern and the mirror image are visually connected to each other, and thus the light effect pattern and the mirror image can be visually connected and extended inward to form a tunnel shape. The extending direction of the tunnel is parallel to the normal direction of the first optical unit 220 or the second optical unit 230.

In some examples, the first sidewall 2121 may include a light-transmitting portion 2125, a light-shielding portion 2126, and a light-shielding portion 2127. The light transmitting portion 2125 and the light shielding portion 2126 may be arranged along an arrangement direction of the first optical unit 220 and the second optical unit 230. The light transmitting portions 2125 and the second light shielding portions 2127 are arranged at intervals along the extending direction of the light guide 212.

In some examples, the light shielding portion 2126 is correspondingly disposed in a closed loop or an open loop, and the light transmitting portion 2125 and the light shielding portion 2127 are connected to each other to be correspondingly connected in a closed loop or an open loop, so that the light guide 212 is disposed in a closed loop or an open loop.

In this case, the light shielding part 2126 may function to separate the light effect pattern and the mirror image and the visual effect between the mirror image and the mirror image. The light shielding portion 2127 may have an effect of forming a discontinuous light effect pattern. In addition, the specific structure of the light shielding portion 2127 may refer to the light shielding portion 2126, that is, the light shielding portion 2127 may be formed of a third light shielding member 2127a provided on the first side wall 2121 of the light guide 212. Referring to fig. 9, the third light-shielding member 2127a may be a light-shielding paint layer applied to the first side wall 2121, or may be light-shielding foam (black foam) provided inside the first side wall 2121. In other examples, the light shielding portions 2126, 2127 may cooperate with the light transmitting portion 2125 to form a specific pattern on the surface of the first sidewall 2121.

In other examples, the shape of the reflective cavity 213 may be further changed by changing the shape of the first sidewall 2121 to function as a change in the light efficiency pattern.

Specifically, the first sidewall 2121 encloses and forms the reflective cavity 213 having a predetermined cross-sectional shape. The preset cross-sectional shape can be Chinese characters, letters, cartoon patterns, polygons, regular or irregular patterns. In some examples, the cross-sectional direction may be parallel to the first optical unit 220 or parallel to the second optical unit 230.

In particular, see fig. 10a, 10b, 10c, 10d, 10e and 10f. The shape of the preset section can be triangle, quadrangle, hexagon, nine-sided or twelve-sided. The shape of the preset section can of course also be rectangular, regular hexagonal, regular nonagon or regular dodecagon. Likewise, the shape of the predetermined cross section may be pentagonal, heptagonal, octagonal, or the like.
