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, for headphones having a light emitting module, the degree of the visual effect of the headphones depends in large part on the complexity of the light emitting module, and in order to improve the visual effect, the light emitting module is often designed into various complex appearances (e.g., cartoon patterns, geometric patterns, etc.). However, as the appearance complexity of the light emitting module increases, the volume of the light emitting module also increases, so that in order to improve the comfort level of the user wearing the earphone, the burden of the user wearing the earphone is reduced, and people do not want to have the light emitting module excessively large volume, which results in excessively bulky earphone body. 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 10 and a light emitting module 20. The light emitting module 20 is disposed on the earphone body 10, and can emit light to increase the visual effect of the earphone 1.

Taking the headphone 1 as an example, the headphone body 10 mainly includes a headband 101, an earmuff 102, a speaker (not shown in the figure), and an ear pad 103, which are not further limited herein. The number of the earshells 102 may be two, and the two earshells 102 may be connected to both ends of the headband 101, respectively. Inside the earmuff 102, a speaker is provided for converting an electric signal into an acoustic signal for output. The ear pad 103 is disposed inside the earmuff 102 for fitting to the ear of the user.

The light emitting module 20 may be provided in the ear shell 102, but may be provided in the headband 101, and is not particularly limited. Referring to fig. 1, the light module 20 may be disposed on the earshell 102. In some examples, the earshell 102 may have a mounting cavity formed therein that is open on one side, and the light module 20 may be received within the mounting cavity. In other embodiments, the light module 20 may also be mounted on the outer wall of the earshell 102. The light emitting module 20 may be disposed on the earmuff 102 in a variety of ways, which are not particularly limited herein.

Referring to fig. 2 and 3, in some examples, the light emitting module 20 may include an optical assembly 200 and a light emitting assembly 210. Wherein the light emitting assembly 210 may include a light emitting member 211 for emitting light. In other examples, the light 211 may also be referred to as a light source. The optical assembly 200 may include an optical lens and/or an optical lens for reflecting and/or transmitting light of the light emitting assembly 210.

Specifically, referring to fig. 4, the light emitting assembly 210 may include a light emitting member 211 and a light guiding member 212. The light emitting member 211 may be disposed on the light guide 212 for emitting light to the light guide 212. The light guide 212 may be disposed on the earphone body 10 for guiding the light emitted from the light emitting element 211. In some examples, light guide 212 may also be referred to as a light guide plate or a light guide body.

Referring to fig. 5, the optical assembly 200 may include a first optical element 201 and a second optical element 202. The first optical element 201 and the second optical element 202 may be disposed opposite and spaced apart. A reflective space 2000 may be formed between the first optical element 201 and the second optical element 202. The first optical element 201 and the second optical element 202 may be used to reflect light rays entering the reflective space 2000, respectively. In addition, the first optical element 201 may be used to allow light to pass through so that the light of the reflective space 2000 can be transmitted out of the first optical element 201.

In some examples, the first optical element 201 may be a half mirror. In some examples, the first optical element 201 may include a first light-transmitting substrate 2010 and a transflective film 2011 disposed on the first light-transmitting substrate 2010. In other examples, the semi-transparent and semi-reflective optical film 2011 may be obtained by surface treatment of the first transparent substrate 2010, that is, the semi-transparent and semi-reflective optical film 2011 may be integral with the first transparent substrate 2010.

In some examples, the second optical element 202 may be a mirror. In some examples, the second optical element 202 may include a second light transmissive substrate 2020 and a light reflective film layer 2021 disposed on the second light transmissive substrate 2020. In other examples, the light reflecting film 2021 may also be obtained by subjecting the second light transmitting substrate 2020 to a surface polishing treatment, that is, the light reflecting film 2021 may be integral with the second light transmitting film. The second light-transmitting substrate 2020 may be the same as the first light-transmitting substrate 2010 or may be different from the first light-transmitting substrate 2010.

In some examples, the first light transmissive substrate 2010 and the second light transmissive substrate 2020 may be disposed in a plate-like configuration. The light reflecting film 2021 may be disposed or formed on a side of the second light-transmitting substrate 2020 facing the first optical element 201. The transflective optical film 2011 may be disposed or formed on a side of the first transparent substrate 2010 facing the first optical element 201. In other examples, the light reflecting film 2021 may also be disposed or formed on a side of the second light-transmitting substrate 2020 facing away from the first optical component 201. Similarly, the half-transmissive and half-reflective optical film 2011 may be disposed or formed on a side of the first light-transmissive substrate 2010 facing away from the first optical element 201.

In some examples, the light emitted by the light emitting element 211 may be transmitted through the second optical element 202 under the guidance of the light guide 212, or enter the reflective space 2000 between the first optical element 201 and the second optical element 202 from the lateral direction. In this case, the light emitted from the light emitting element 211 may form a predetermined pattern, and the predetermined pattern may be repeatedly reflected between the first optical element 201 and the second optical element 202 to form a plurality of mirror images extending along a direction in which the first optical element 201 points to the second optical element 202. The user can observe the tunnel light effect formed by the preset pattern and the multiple mirror images through the first optical element 201 (see fig. 6). In addition, by using the reflection of the first and second optical elements 201 and 202, the volume of the light emitting module 20 can be controlled within a reasonable range while improving the visual effect of the light emitting module 20.

It should be noted that, the rings in fig. 6 show a certain light effect pattern and multiple mirror images thereof, respectively. In addition, the light effect patterns in the figures are circular, and the effect of conveniently showing how the light effect patterns and the mirror images form tunnel light effects is mainly achieved. In other words, a circular ring is only one simple, basic embodiment of a light effect pattern, the shape of which is not necessarily a circular ring (described later).

The light emitting module 20 is further described below by way of example in the first and second embodiments, respectively.

Example one

Referring to fig. 7 and 8, in some embodiments, light emitted from the light emitting assembly 210 may be incident to the reflective space 2000 between the first and second optical elements 201 and 202 from a side direction.

Specifically, in some examples, the light guide 212 may be provided to the earphone body 10. Light guide 212 may include a side wall 2122 and a bottom wall 2121 that are interconnected. The bottom wall 2121 may be located on a side of the second optical element 202 facing away from the first optical element 201. In other words, the first optical element 201 may be disposed on a side of the second optical element 202 facing away from the bottom wall 2121. The side wall 2122 may extend from the bottom wall 2121 toward the first optical element 201.

A receiving space 2123 (shown in fig. 4) may be defined between the side wall 2122 and the bottom wall 2121. The second optical element 202 may be disposed within the receiving space 2123. The first optical element 201 is disposed in the accommodating space 2123 or overlaps an end of the side wall 2122 away from the bottom wall 2121 and is farther from the bottom wall 2121 than the second optical element 202. The bottom wall 2121 may have a plate shape, and the second optical element 202 may be disposed in the accommodating space 2123 and laid on the bottom wall 2121.

The light emitting member 211 may be disposed at the bottom wall 2121 for emitting light toward the bottom wall 2121. The light 211 may include a circuit board 2111 and at least one lamp bead (not shown). Specifically, the lamp beads may be LED lamps. The circuit board 2111 may be provided on a side of the bottom wall 2121 remote from the second optical element 202. In other words, the light emitting member 211 and the second optical element 202 may be disposed at both sides of the bottom wall 2121, respectively. At least one light bulb is disposed on a side of the circuit board 2111 facing the light guide 212. The bottom wall 2121 may be provided with at least one light receiving hole 2124 (shown in fig. 4). At least one lamp bead is embedded in at least one lamp accommodating hole 2124 in a one-to-one correspondence.

Alternatively, the number of the lamp beads may be 1, and correspondingly, the number of the lamp receiving holes 2124 may be 1. A light receiving hole 2124 may be provided in the center of the bottom wall 2121. Alternatively, the number of the lamp beads may be plural, and correspondingly, the number of the lamp receiving holes 2124 may be plural (for example, 4, 5, or 8). The plurality of light receiving holes 2124 may be arranged in an annular array about the center of the bottom wall 2121. In this case, the light emitted from the lamp beads is transmitted through the light guide 212, and a light effect pattern having uniform brightness can be formed on the sidewall 2122.

In this case, the light emitting member 211 may emit light toward the bottom wall 2121. As shown in fig. 7, the light guide 212 may guide the light emitted from the light emitting element 211 to propagate from the bottom wall 2121 to the side wall 2122 and to be emitted from the side wall 2122 into the reflective space 2000. In addition, the arrows in the figures only exemplarily describe the general direction of light propagation, and do not represent the exact propagation path of light.

Specifically, the outer surface of the side wall 2122 is formed with a guiding slope 21220 inclined inward in the direction of the second optical element 202 toward the first optical element 201 for guiding the light propagating to the side wall 2122 through the bottom wall 2121 to the reflecting space 2000.

Further, the outer peripheral surface of the side wall 2122 may be frosted. The upper and lower surfaces of the bottom wall 2121 may be frosted. In this case, the light emitted from the light emitting member 211 after entering the light guide 212 can be reflected by the upper and lower surfaces of the bottom wall 2121 and the outer surface of the side wall 2122, and further guided by the light guide to propagate from the bottom wall 2121 to the side wall 2122 and be reflected to the reflection space 2000 via the guide slope 21220.

The sidewall 2122 may be annularly disposed. The side wall 2122 may be provided in a closed loop or an open loop. Where the sidewalls 2122 are arranged in a closed loop may refer to the sidewalls 2122 surrounding and joined end-to-end to form a continuous closed loop. The open-loop configuration of the sidewalls 2122 may mean that the sidewalls 2122 are not joined end-to-end or that the sidewalls 2122 form an intermittent open loop around them. It should be noted that the side wall 2122 is provided 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.

Further, as shown in fig. 8, in some examples, the inner surface of the side wall 2122 may have a light-transmitting portion 2122 (a) and a light-shielding portion 2122 (b). The light-transmitting portion 2122 (a) serves to allow light to enter the reflecting space 2000. The light shielding portion 2122 (b) serves to allow shielding light to enter the reflecting space 2000.

The light shielding portion 2122 (b) and the light transmitting portion 2122 (a) may be provided in a ring shape, respectively. The light guide 212 may guide the light emitted from the light emitting member 211 to be emitted from the light transmitting portion 2122 (a) into the reflection space 2000. The light shielding portion 2122 (b) may shield the light from entering the reflection space 2000 between the first optical element 201 and the second optical element 202. In other words, the light-transmitting portion 2122 (a) may refer to a region of the sidewall 2122 that allows the light Xu Guangxian to transmit. The light shielding portion 2122 (b) may refer to a region of the side wall 2122 that does not allow light to pass through. That is, the sidewall 2122 may include two regions having different light transmittance.

Alternatively, the number of light shielding portions 2122 (b) and light transmitting portions 2122 (a) may each be at least one. The at least one light shielding portion 2122 (b) and the at least one light transmitting portion 2122 (a) are alternately arranged in the direction from the second optical element 202 to the first optical element 201.

Alternatively, the number of light shielding portions 2122 (b) and light transmitting portions 2122 (a) may each be at least one. The light shielding portions 2122 (b) and the light transmitting portions 2122 (a) are alternately arranged along the circumferential direction of the side wall 2122.

Alternatively, the light shielding portion 2122 (b) may include a first sub light shielding portion and a plurality of second sub light shielding portions. The first sub-shading part is annularly arranged. The number of the light transmitting portions 2122 (a) is plural. The plurality of light transmitting portions 2122 (a) and the second sub-light shielding portions are alternately arranged along the circumferential direction of the side wall 2122, and are alternately arranged with the first sub-light shielding portions in the direction in which the second optical element 202 faces the first optical element 201.

In other examples, the light emitting assembly 210 may further include a flag 2125 disposed on a side of the sidewall 2122 facing the reflective space 2000.

Wherein the light blocking member 2125 may be a black foam or a black paint sprayed onto the surface of the sidewall 2122.

In some examples, the flag 2125 can have a body portion 2125 (a) and a fitting portion 2125 (b). Wherein the body portion 2125 (a) may be adapted to cooperate with the sidewall 2122 to form a light-transmitting portion 2122 (a) and a light-shielding portion 2122 (b). Fitting portion 2125 (b) serves to connect side wall 2122 and second optical element 202.

Alternatively, the body portion 2125 (a) of the flag 2125 may be provided to a partial region of the sidewall 2122. The side wall 2122 may form a light shielding portion 2122 (b) at a partial region of the main body portion 2125 (a) where the light shielding member 2125 is provided. The sidewall 2122 may form a light-transmitting portion 2122 (a) at other partial regions of the main body portion 2125 (a) where the light-blocking member 2125 is not provided.

Alternatively, the body portion 2125 (a) of the light shielding member 2125 may include a light shielding region that blocks light and a light transmitting region that allows light to pass through. The side wall 2122 may form a light shielding portion 2122 (b) in a partial region corresponding to the light shielding region. The sidewall 2122 may form a light-transmitting portion 2122 (a) in a partial region corresponding to the light-transmitting region.

Alternatively, the fitting portion 2125 (b) of the light shielding member 2125 may be formed at the outer periphery of the main body portion 2125 (a). The light blocking member 2125 may be disposed to the light guide 212 in such a manner that the fitting portion 2125 (b) overlaps the sidewall 2122 and the body portion 2125 (a) contacts the inner surface of the sidewall 2122. In this case, the light blocking member 2125 can be easily detached.

Alternatively, a side of the fitting portion 2125 (b) facing away from the main body portion 2125 (a) may also be provided with a fitting groove for fitting the first optical element 201. That is, the first optical element 201 may be disposed at the assembling portion 2125 (b) of the light shielding member 2125, and then indirectly disposed at the top of the sidewall 2122. When the first optical element 201 is fitted to the fitting groove of the fitting portion 2125 (b), the contact area of the first optical element 201 and the fitting portion 2125 (b) can be increased, thereby improving the stability of the fitting of the first optical element 201.

In addition, if the light blocking member 2125 is black paint sprayed on the sidewall 2122, the first optical element 201 can be also considered to be directly disposed on the light guiding member 212.

In summary, in the first embodiment, the light emitted by the light emitting element 211 can be transmitted to the side wall 2122 along the bottom wall 2121, and the side wall 2122 has the light transmitting portion 2122 (a) and the light shielding portion 2122 (b) with different light transmittance, so that the light forms a ring-shaped light effect pattern on the inner surface of the side wall 2122, and the ring-shaped light effect pattern can form a tunnel light effect under the reflection of the first optical element 201 and the second optical element 202.

Example two

Referring to fig. 9 and 10, in some embodiments, light emitted from the light emitting component 210 may be incident to the reflective space 2000 between the first optical element 201 and the second optical element 202 through the second optical element 202.

Specifically, in some examples, the light guide 212 may be provided to the earphone body 10. At least a portion of the light guide 212 (i.e., the bottom wall 2121 of the light guide 212) may be located on a side of the second optical element 202 facing away from the first optical element 201.

Light guide 212 may include a bottom wall 2121 and side walls 2122. The bottom wall 2121 is located on a side of the second optical element 202 facing away from the first optical element 201. The side wall 2122 is connected to a side of the bottom wall 2121 near the second optical element 202, and a receiving space 2123 is defined between the side wall 2122 and the bottom wall 2121. The second optical element 202 may be disposed within the receiving space 2123. The first optical element 201 is disposed in the accommodating space 2123 or overlaps an end of the side wall 2122 away from the bottom wall 2121 and is farther from the bottom wall 2121 than the second optical element 202.

Further, the bottom wall 2121 may have a plate shape, and the second optical element 202 may be disposed in the accommodating space 2123 and laid on the bottom wall 2121.

Further, the second optical element 202 may include a reflective region 202 (a) and a transmissive region 202 (B). The light guide 212 is configured to at least partially guide light rays from the light-transmitting region 202 (B) into the reflective space 2000 between the first optical element 201 and the second optical element 202. The reflective region 202 (a) of the second optical element 202 may be used to reflect light rays that enter the reflective space 2000 between the first optical element 201 and the second optical element 202.

The second optical element 202 may include a second light-transmitting substrate 2020 and a light-reflecting film layer 2021 disposed on a partial region of the second light-transmitting substrate 2020. The second light-transmitting substrate 2020 forms the reflective region 202 (a) in a partial region where the light-reflecting film 2021 is provided, and forms the light-transmitting region 202 (B) in other partial regions where the light-reflecting film 2021 is not provided. In some examples, a complete retroreflective film 2021 may be disposed on the second light transmissive substrate 2020 and a film removal technique (e.g., laser engraving) may be used to remove portions of the retroreflective film 2021 to form the light transmissive region 202 (B).

Alternatively, the light-transmitting region 202 (B) may be provided in a preset shape. The preset shape is an open loop or a closed loop.

Optionally, the light transmissive region 202 (B) may also include multiple segments of light transmissive sub-regions. The multi-section light-transmitting subregions are arranged at intervals and enclose into an intermittent surrounding shape or an intermittent semi-surrounding shape.

In addition, the reflective region 202 (a) includes a first reflective sub-region 202 (a 1) and a second reflective sub-region 202 (a 2). The first reflective sub-area 202 (a 1) is located inside the transmissive area 202 (B). The second reflection sub-region 202 (a 2) is located outside the light-transmitting region 202 (B) and is disposed in an open-loop or closed-loop shape. In this case, when the viewing angle of the user is inclined compared to the central axis of the first optical element 201 and/or the second optical element 202, the tunnel light effect can be observed.

Further, the light emitting assembly 210 may further include a light blocking member 2125 disposed at least on a side of the sidewall 2122 facing the receiving space 2123. The light blocking member 2125 may block light emitted into the receiving space 2123 through the sidewall 2122. It is contemplated that in the second embodiment, the side wall 2122 mainly serves to support the first optical element 201, and thus, in some examples, the light guide 212 may not include the side wall 2122, in which case the first optical element 201 may be fixed by other means. Of course, the light blocking member 2125 may also have a fitting portion 2125 (b), and the specific structure of the fitting portion 2125 (b) may be described with reference to the related embodiment 1, and have equivalent technical effects, which will not be described in detail herein.

Optionally, the light emitting assembly 210 may also include a light balancing paper. The light equalizing paper is laid between the bottom wall 2121 and the second optical element 202.

In summary, in the second embodiment, the light-emitting element 211 is configured to emit light to the bottom wall 2121, and the emitted light can be incident into the first optical element 201 and the second optical element 202 through the light-transmitting region 202 (B) of the second optical element 202 after being transmitted through the bottom wall 2121. Since the light-transmitting region 202 (B) of the second optical element 202 has a predetermined shape, a light effect pattern can be formed on the surface of the second optical element 202, and the light effect pattern can be reflected between the reflective region 202 (a) of the second optical element 202 and the first optical element 201 to form a tunnel light effect.

It should be noted that, since the light effect pattern is a pattern formed by light observed by the user, the different viewing angles may cause the observed light effect pattern to have different shapes, so the light effect pattern referred to in the present application only serves to facilitate description, and should not be considered as a limitation of the light emitting module 20.

Unlike the related art, the light emitted from the light emitting element 211 may enter the reflective space 2000 between the first and second optical elements 201 and 202 laterally or through the second optical element 202 by being guided by the light guiding element 212, may be repeatedly reflected between the first and second optical elements 201 and 202, and may be transmitted out through the first optical element 201, so that a user may see a plurality of layered light effect patterns (tunnel light effects) extending along the directions of the first and second optical elements 201 and 202 through the first optical element 201, and thus may improve visual effects.

In some examples, as shown in fig. 11, bottom wall 2121 may extend further outward from side wall 2122 to form an extension 2126 for guiding light directed through bottom wall 2121 outward.

Further, referring to fig. 11 and 12, the light emitting module 20 may further include a lateral light guide 2127. Optionally, lateral light guides 2127 are disposed around the periphery of light guide 212. The lateral light guide 2127 may be sleeved around the outer circumference of the extension 2126. Alternatively, the lateral light guides 2127 may be integrally formed with the extension 2126. In this case, the light emitted by the light emitting element 211 may be guided by the bottom wall 2121 of the light guiding element 212 and then spread outwards through the extension 2126 and the lateral light guiding element 2127 to form lateral light effect, so as to further increase the cool and dazzling degree of the visual effect of the light emitting module 20.

Alternatively, the extension 2126 may tilt away from the side facing away from the second optical element 202 during extension, such that the extension 2126 surrounds the light-emitting element 211 disposed on the bottom wall 2121.

In addition, in order to reduce the loss of the light emitted from the light emitting element 211 when the light propagates in the light guide 212, a reflective layer may be formed by performing a sand blast treatment on the outer surface of the light guide 212, so as to enable the light of the light emitting element 211 to be reflected after propagating to the outer surface, so as to reduce the probability that the light passes through the outer surface and leaves the light guide 212 during the propagation process.

Specifically, in the light emitting assembly 210 according to the first embodiment, the upper and lower surfaces of the bottom wall 2121, the upper and lower surfaces of the extension 2126, and the outer peripheral surface of the side wall 2122 of the light guide 212 may be sandblasted to form the reflective layer. In this case, the light emitted from the light emitting member 211 can be made incident to the reflection space 2000 between the first and second optical elements 201 and 202 from the inner surface of the sidewall 2122 of the light guide 212 with high efficiency.

In the light emitting module 210 according to the second embodiment, the lower surface of the bottom wall 2121, the upper and lower surfaces of the extension 2126, the inner surface and the outer peripheral surface of the side wall 2122 of the light guide 212 may be sandblasted to form the reflective layer. In this case, the light emitted from the light emitting member 211 can be made incident on the second optical element 202 from the upper surface of the bottom wall 2121 of the light guide 212 with high efficiency.

In addition, by performing sand blasting on the upper and lower surfaces of the extension 2126 and the outer peripheral surface of the sidewall 2122 to form a reflective layer, the probability of light being emitted through the upper and lower surfaces of the extension 2126 and the outer peripheral surface of the sidewall 2122 can be reduced, so that the tunnel light efficiency and/or the lateral light efficiency can be better projected, and the attention of a user can be focused on the tunnel light efficiency and/or the lateral light efficiency.

In some examples, the light module 20 may also include a housing 2128. The housing 2128 may surround the outer periphery of the sidewall 2122. The housing 2128 defines a light-transmissive window. The housing 2128 may cover the first optical element 201. The light-transmitting window is disposed opposite to the first optical element 201, so as to transmit the light emitted from the first optical element 201.

Further, an end of the housing 2128 remote from the light-transmissive window may be supported to the lateral light guide 2127. The side guides 2127 guide the light guided by the light guides 212 to be emitted from the circumference of the housing 2128 to the outside of the housing 2128.

The lateral light guide 2127 may include an interconnecting base and insert. The base extends circumferentially of the housing 2128 so that an end of the housing 2128 remote from the light-transmissive window can be supported to the base. The insert is provided at the bottom and may protrude toward the housing 2128. Correspondingly, the housing 2128 is provided with a clamping groove 2129, and the embedded portion is embedded and clamped in the clamping groove 2129.

Referring to fig. 13, in some examples, the light effect pattern may be any of the patterns of fig. 13. In particular, the shape of the light effect pattern may be polygonal, for example triangular, quadrilateral, hexagonal, nonagonal or dodecagonal. The shape of the light effect pattern can of course also be rectangular, regular hexagonal, regular nonagon or regular dodecagon. Likewise, the shape of the light effect pattern may be pentagonal, heptagonal, octagonal, or the like.

In other examples, the shape of the light effect pattern may also be a regular pattern formed by a combination of straight lines and curved lines, such as a pattern formed by smooth transitions of four corners of a semicircle, a square, or a racetrack shape (oblong). In addition, the shape of the light effect pattern can also be a regular pattern formed by combining curves with different curvatures, such as a drop shape, an ellipse shape and a shield. In addition, the shape of the light effect pattern may be a regular pattern formed by combining straight lines.

Corresponding to the first embodiment in which the light effect pattern is formed on the inner surface of the sidewall 2122, the shape of the sidewall 2122 may be changed to adjust the light effect pattern. For embodiment 2 in which the light effect pattern is formed on the second optical element 202, the light effect pattern can be adjusted by adjusting the distribution shapes of the reflection region 202 (a) and the light transmission region 202 (B) in the second optical element 202.

In summary, the light emitted by the light emitting element 211 of the present application can be guided by the light guiding element 212 to enter the reflective space 2000 between the first optical element 201 and the second optical element 202 laterally, and can be repeatedly reflected between the first optical element 201 and the second optical element 202, and can be transmitted out through the first optical element 201, so that a user can see a plurality of layered light effect patterns (tunnel light effect) extending along the direction of the first optical element 201 and the second optical element 202 through the first optical element 201, and further can improve the visual effect. In addition, the light emitted by the light emitting element 211 can be guided by the bottom wall 2121, the extension 2126, and the lateral light guiding element 2127 of the light guiding element 212 to achieve lateral light effect of the outer direction Zhou Fashe, so that the cool degree of the visual effect of the earphone 1 can be further improved.
