Description

Technical Field

[0001] This application claims the priority of Chinese Patent Application No. 202320905870.8, titled "Optical Module, Electronic Device, and Vehicle", filed with the China National Intellectual Property Administration on April 16, 2023, which is incorporated herein by reference in its entirety.

[0002] Embodiments of this application relate to the field of optical technology, and more particularly, to optical modules, electronic devices, and vehicles.

Background Art

[0003] With the continuous development of technology, electronic devices that can simultaneously realize an acoustic playback function and an optical effect function have received wide attention. Such electronic devices include an acoustic module and an optical module, and the optical module may be configured to emit light to implement an optical effect function. However, light mixing occurs in the light guiding member of the optical module, and the transmitted light of the optical module becomes uncontrollable. Therefore, only the production of monochromatic light can be formed.

Summary of the Invention

[0004] The purpose of the embodiments of this application is to provide an optical module, an electronic device, and a vehicle to solve the problem of related technologies that the transmitted light of the optical module is uncontrollable.

Means for Solving the Problems

[0005] To achieve the above object, the embodiments of this application provide the following solutions.

[0006] According to one aspect, one embodiment of the present application provides an optical module. The optical module includes a light source, a light guide structure, and a light transmission unit. The light source includes a plurality of sub-light sources. The light guide structure includes a plurality of light guide strips. Each sub-light source is located on the light incident side of the corresponding light guide strip. The light transmission unit is located on the light-emitting side of the plurality of light guide strips. The light guide structure further includes at least one light-shielding portion, and every two adjacent light guide strips are separated by one light-shielding portion.

[0007] In the optical module provided in this embodiment of the present application, light emitted from multiple sub-light sources is incident on the corresponding light guide strip through the light-incident side of the light guide strip, and then the light may be emitted from the light-emitting side of the light guide strip to the light-transmitting unit. In addition, since a light-shielding portion is placed between each pair of adjacent light guide strips, the light emitted from the multiple sub-light sources can be prevented from mixing within the light guide structure, and as a result, the light emitted from the multiple sub-light sources is emitted to different regions of the light-transmitting unit via the corresponding light guide strips, and the light-transmitting unit simultaneously performs the effect of multiple colors of light. Note that the light guide member in the related art does not include a light-shielding portion. Therefore, after the light guide structure in this embodiment of the present application is replaced with a light guide member, the light emitted from the light source is mixed with the light guide member. This makes the light emitted to the light-transmitting unit uncontrollable (i.e., the transmitted light of the optical module is uncontrollable), making it easier to form a single gradient color. The optical module provided in this embodiment of the present application can adequately solve the aforementioned technical problems.

[0008] In some embodiments, the extension direction of the light guide strip is a first direction, and the light guide structure includes a first region and a second region arranged in the first direction. The first region is closer to the light source than the second region. The portion of the light guide strip that is within the second region includes a first surface closer to the light transmission unit. The portion of the light shielding that is within the second region includes a second surface closer to the light transmission unit. The first surface is closer to the light transmission unit than the second surface. In this embodiment, in the second region, the first surface is positioned closer to the light transmission unit than the second surface, i.e., in the second region, the light guide strip is positioned closer to the light transmission unit than the light shielding portion. As a result, light transmitted by multiple light guide strips can reach different regions of the light transmission unit, and the gap regions between adjacent light guide strips are used, allowing a light mixing effect to be generated before light from opposing sides of adjacent light guide strips enters the light transmission unit. Thus, transition colors can be generated in the transition regions between different colored light regions of the light transmission unit, enhancing the visual effect.

[0009] In some embodiments, the first surface includes a contact surface, a first connecting surface, and a second connecting surface. The contact surface is in contact with the light transmission unit. The arrangement direction of the multiple light guide strips is a second direction. The first and second connecting surfaces are located on either side of the contact surface in the second direction, with a gap between the first connecting surface and the light transmission unit, and a gap between the second connecting surface and the light transmission unit. The gap between the first connecting surface and the light transmission unit gradually decreases toward the contact surface, and / or the gap between the second connecting surface and the light transmission unit gradually decreases toward the contact surface. In this embodiment, the gap between the first connecting surface and the light transmission unit is set to gradually decrease toward the contact surface, which can result in an increase in the amount of light emitted from the first connecting surface to the light transmission unit. The gap between the second connecting surface and the light transmission unit is set to gradually decrease toward the contact surface, which can result in an increase in the amount of light emitted from the second connecting surface to the light transmission unit. Furthermore, the inclination of the first and second connection surfaces can be further modified to adjust the light mixing effect of the light emitted from the first and second connection surfaces. As a result, the transition light effect of the transition region between different colored light regions of the light transmission unit can be further adjusted, enhancing the visual effect.

[0010] In some embodiments, the light transmission unit includes a light scatterer. Here, a light scatterer refers to a structure that reflects light incident on the light scatterer in multiple directions, thereby achieving a scattering effect. In this embodiment, the light transmission unit is configured to include a light scatterer, which can result in improved lighting effects, a more aesthetically pleasing effect, and further enhanced product competitiveness.

[0011] In some embodiments, the acoustic reflection structure is located on one side of the light transmission unit, away from the light guide structure. In this embodiment, the acoustic reflection structure can reflect acoustic waves, resulting in the scattering of acoustic waves in different directions, generating diffraction and altering the output sound quality effect. In this case, the light transmission unit can achieve both light effects and acoustic tuning effects.

[0012] In some embodiments, the acoustic reflection structure includes a plurality of first groove structures. This arrangement allows for adjustment of the depth of the plurality of first groove structures to obtain different sound qualities. In this case, the shape of the acoustic reflection structure is equivalent to that of a Schroeder diffuser, where acoustic waves are reflected by the plurality of first groove structures, resulting in the acoustic waves being scattered in different directions, generating diffraction and altering the output sound quality effect.

[0013] In some embodiments, the plurality of first groove structures are strip-shaped, the extension direction of the plurality of first groove structures is the same as the extension direction of the plurality of light guide strips, and the arrangement direction of the plurality of first groove structures is the same as the arrangement direction of the plurality of light guide strips. This deposition may result in one or more light guide strips being located on the back surface of one first groove structure, or one or more light guide strips being located on the back surface of a lateral edge structure of a first groove structure, or the same light guide strip being located on the back surfaces of both adjacent first groove structures and edge structures. Here, the back surface refers to one side of the light transmission unit, the side closer to the light guide structure. In this embodiment, different colored light effects can be formed at different locations on the first groove structures and at different locations on the edge structures.

[0014] In some embodiments, the orthogonal projection of the first groove structure onto a reference plane at least partially overlaps with the orthogonal projection of the light guide strip onto the reference plane, where the reference plane is the plane on which the first and second directions are located. In this example, the orthogonal projection of the first groove structure onto the reference plane is set to at least partially overlap with the orthogonal projection of the light guide strip onto the reference plane, so that a higher luminance light effect can be generated at the location of the first groove structure, a different color light effect can be generated at different locations of the first groove structure, and a darker transition light effect can be generated at the location of the edge structure. Thus, the light transmission unit can simultaneously achieve multiple color light effects, and a better transition color or darker region can be formed between adjacent lights of two colors.

[0015] In some embodiments, the second groove structure is located on a surface of the light-transmitting unit that is close to the light guide structure, and at least a portion of the light guide strip extends into the second groove structure. In this embodiment, at least a portion of one light guide strip may extend into the second groove structure, or at least a portion of two or more light guide strips may extend into the same second groove structure. The second groove structure is located on a surface of the light-transmitting unit that is close to the light guide structure, and as a result, the second groove structure can be used to provide positioning and support functions for the light guide strip. Furthermore, this helps to increase the amount of light emitted from the light guide strip to the light-transmitting unit, and helps to improve the luminous brightness of the light-transmitting unit.

[0016] In some embodiments, the surface of the light-transmitting unit that is close to the light-guide structure includes a barrier layer, and the transmittance range of the barrier layer is 30% to 60% (including 30% and 60%). For example, the transmittance of the barrier layer may be 30%, 35%, 50%, 55%, 60%, etc. For example, the numerical range of the transmittance of the barrier layer may be 40% to 45% (including 40% and 45%). For example, the transmittance of the barrier layer may be 40%, 41%, 42%, 43%, 44%, 45%, etc. In this embodiment, if the transmittance of the barrier layer is close to or equal to 30%, the barrier layer can have an effective shielding effect on the light-guide structure. In other words, when the light-guide structure is dark, it is difficult for the human eye to see the light-guide structure from the opposite side of the light-transmitting unit. However, when the light-guide structure is bright, the light from the light-guide structure can still be radiated to the light-transmitting unit through the barrier layer. Furthermore, if the transmittance of the barrier layer is close to or equal to 60%, the barrier layer can have some degree of shielding effect on the light guide structure. In this case, if the light guide structure is in a bright state, more light from the light guide structure can be radiated to the light transmission unit through the barrier layer.

[0017] In another aspect, one embodiment of the present application provides an electronic device. The electronic device includes an acoustic module and an optical module. The optical module includes a light source, a light guide structure, and a light transmission unit. The light source includes a plurality of sub-light sources. The light guide structure includes a plurality of light guide strips. Each sub-light source is located on the light incident side of the corresponding light guide strip. The light transmission unit is located on the light-emitting side of the plurality of light guide strips. The light guide structure further includes at least one light-shielding portion, and every two adjacent light guide strips are separated by one light-shielding portion. The light transmission unit is located between the light guide structure and the acoustic module. The acoustic reflection structure is located on one side of the light transmission unit, on the side closer to the acoustic module.

[0018] According to the electronic device provided in this embodiment of the present application, in the optical module, light emitted from multiple sub-light sources enters the corresponding light guide strip through the light-incident side of the light guide strip, and then the light can be emitted from the light-emitting side of the light guide strip to the light-transmitting unit. In addition, since a light-shielding portion is placed between each of two adjacent light guide strips, the light emitted from the multiple sub-light sources can be prevented from mixing within the light guide structure, and as a result, the light emitted from the multiple sub-light sources is emitted to different regions of the light-transmitting unit via the corresponding light guide strips, and the light-transmitting unit simultaneously performs the effect of multiple colors of light. Note that the light guide member in the related art does not include a light-shielding portion. Therefore, after the light guide structure in this embodiment of the present application is replaced with a light guide member, the light emitted from the light source is mixed with the light guide member. This makes the light emitted to the light-transmitting unit uncontrollable (i.e., the transmitted light of the optical module is uncontrollable), and a single gradient color is easily formed. The optical module in the electronic device provided in this embodiment of the present application can successfully solve the aforementioned technical problems. In addition, since the light transmission unit is located between the light guide structure and the acoustic module, the acoustic reflection structure is located on one side of the light transmission unit, closer to the acoustic module. The acoustic reflection structure can reflect acoustic waves, resulting in the scattering of acoustic waves in different directions, generating diffraction and altering the output sound quality effect. In this case, the light transmission unit can achieve both a light effect and an acoustic tuning effect. Therefore, the electronic device provided in this embodiment of the present application can simultaneously realize a sound playback function and a light effect function.

[0019] In yet another embodiment, one embodiment of the present application provides a vehicle. The vehicle includes a vehicle body. Any one of the optical modules of the above embodiments is located in the vehicle body, and / or any one of the electronic devices of the above embodiments is located in the vehicle body.

In addition, since the vehicle has the optical module and / or the electronic device in any one of the foregoing embodiments, the vehicle has the beneficial effects of the optical module and / or the electronic device in any one of the foregoing embodiments. Details are not repeated here.

[0027] In embodiments of this application, for example, up, down, left, right, front, and back are relative directional indicators used to describe the structure and movement of different parts of this application. These indicators are appropriate when the part is in the position shown in the figure. However, as the description of the part's position changes, these directional indicators change accordingly.

[0028] One embodiment of this application provides a vehicle. For example, the vehicle may be an automobile or a non-automobile, and the vehicle may be a fuel vehicle or an electric vehicle. Examples of vehicles include, but are not limited to, automobiles, trucks, buses, etc.

[0029] Figure 1 is a structural diagram of a vehicle 1000 according to one embodiment of the present application, and Figure 2 is a structural diagram of the driver's cab and center console of the vehicle in Figure 1. The vehicle 1000 includes a body 1100. The body 1100 may include a body 1110, tires 1120, a power mechanism (not shown), etc. The body 1110 may be configured to form an engine compartment 1111, a driver's cab 1112, a passenger compartment 1113, a rear trunk 1114, etc.

[0030] The tires 1120 may be mounted below the body 1110, the power mechanism may be mounted inside the engine compartment 1111, and the power mechanism may be connected to the tires 1120 via a transmission. Thus, the power mechanism may transmit power to the tires 1120 to control the rotation of the tires 1120 and move the body 1110 forward or backward.

[0031] The driver's cab 1112 and passenger compartment 1113 are located between the engine compartment 1111 and the rear trunk 1114. The driver's cab 1112 may be close to the engine compartment 1111, and the passenger compartment 1113 may be close to the rear trunk 1114. The driver's cab 1112 may include a driver's seat and a passenger seat. One of the driver's seat and passenger seat is closer to the left side of the body, and the other is closer to the right side of the body. It will be understood that the steering wheel 1115 is located in front of the driver's seat. In front of the driver's seat and passenger seat is the center console area 1116. The passenger compartment 1113 may include multiple occupant positions, for example, positions for two to three occupants. The rear trunk 1114 may be configured to accommodate goods.

[0032] The vehicle 1000 may further include an optical module 100 and / or an electronic device 200. The electronic device 200 is an integrated electronic device with the optical module 100. For example, as shown in Figure 2, the optical module 100 may be located in the center console area 1116, for example, in the center of the left and right directions in the figure. The electronic device 200 may also be located in the center console area 1116, for example, in the center of the left and right directions in the figure. It will be understood that the arrangement of the optical module 100 and / or electronic device 200 in this specification is merely an example. In another embodiment, the optical module 100 and / or electronic device 200 may be alternatively located in a different position on the body.

[0033] Figure 3 is a structural diagram of an electronic device 200 according to one embodiment of this application. Figure 4 is a cross-sectional view of the housing of Figure 3. Figure 5 is a cross-sectional view of the electronic device 200 of Figure 3. The electronic device 200 may include an acoustic module 202 and an optical module 100.

[0034] The acoustic module 202 may implement sound playback functions such as playing music, playing broadcasts, or reading books. For example, the acoustic module 202 may include a first control circuit board 2021 and a loudspeaker 2022, the first control circuit board 2021 being electrically connected to the loudspeaker 2022, and the first control circuit board 2021 being configured to control the loudspeaker to play sound. The optical module 100 may implement a light effect function that forms various cool or warm colors of light, such as red light, green light, blue light, warm white light, and cool white light (the optical module 100 will be described in detail below and will not be described in detail here). Thus, the electronic device 200 may implement both sound playback functions and light effect functions. For example, the light effect function of the optical module 100 may be used in conjunction with the sound playback function of the acoustic module 202. For example, when parameters such as volume, treble range, and bass range of the sound reproduced by the acoustic module 202 change, parameters such as the color and flash frequency of the light generated by the optical module 100 change accordingly, thereby achieving greater versatility.

[0035] For example, the electronic device 200 may further include a housing 201 having a first mounting position 210 and a second mounting position 220. The acoustic module 202 is located at the first mounting position 210, and the optical module 100 is located at the second mounting position 220. At least a portion of the area of ​​the second mounting position 220 may be positioned opposite at least a portion of the area of ​​the first mounting position 210.

[0036] For example, the electronic device 200 may further include a decorative ring 203. The decorative ring 203 may be attached to an opening in the housing 201. The opening may expose the acoustic module 202 and the optical module 100, thereby allowing the sound from the acoustic module 202 to be better diffused from the housing 201 and the light from the optical module 100 to be emitted from the housing 201. The material of the decorative ring 203 is not limited to this embodiment of the present application. The decorative ring 203 may be transparent or opaque and may have any color.

[0037] For example, the support structure 2011 and the fastening structure 2012 may be further arranged on the housing 201. The support structure 2011 may be configured to support the entire electronic device 200, so that the electronic device 200 can be directly placed in a location such as a desktop or counter. The fastening structure 2012 may be configured to connect to external devices such as desktops, counters, and the aforementioned central control console of a vehicle. For example, the fastening structure 2012 may include structures such as screws and bolts, and may further include adhesives for joining.

[0038] In some of the embodiments described above, examples in which the optical module 100 and electronic device 200 are used in a vehicle 1000 are used for illustrative purposes. In addition to the vehicle 1000, it will be understood that the optical module 100 and electronic device 200 provided in this embodiment of the present application may be further used in any other environment in which sound needs to be reproduced and light needs to be generated. For example, the optical module 100 and electronic device 200 may be further used in the home sector, including, but not limited to, bedrooms, living rooms, bathrooms, bars, dance halls, supermarkets, offices, etc. As another example, the optical module 100 and electronic device 200 may be further used in other means of transport other than the vehicle 1000, including, for example, ships, trains, airplanes, etc.

[0039] The optical module 100 provided in this embodiment of the present application will be described below.

[0040] Refer to Figure 5 again. The optical module 100 includes a light source 1, a light guide structure 2, and a light transmission unit 3. Based on this, for example, the optical module 100 may further include a second control circuit board 4, and the light source 1 may be electrically connected to the second control circuit board 4. In some examples, the second control circuit board 4 and the aforementioned first control circuit board 2021 may be electrically connected to the same controller (not shown). In this way, it is convenient to use the same controller to control the acoustic module 202 and the optical module 100. The controller may be a Central Processing Unit (CPU), a general-purpose processor, a Digital Signal Processor (DSP), an Application-Specific Integrated Circuit (ASIC), a Field Programmable Gate Array (FPGA), or other programmable logic devices, transistor logic devices, hardware components, or any combination thereof.

[0041] Figure 6 is a structural diagram of a combination of a light source 1 and a light guide structure 2 according to one embodiment of the present application. As shown in Figure 6, the light source 1 includes a plurality of sub-light sources 11, and the light guide structure 2 includes a plurality of light guide strips 21, with each sub-light source 11 located on the light incident side of the corresponding light guide strip 21. The light transmission unit 3 is located on the light-emitting side of the plurality of light guide strips 21. Here, the number of sub-light sources 11 and the number of light guide strips 21 are not limited. For example, there may be one, two or more sub-light sources 11, and there may be one, two or more light guide strips 21. In Figure 6, an example with six light guide strips and six sub-light sources is used for illustrative purposes.

[0042] For example, one sub-light source 11 may include one or more LED lights. For example, one sub-light source 11 may include red LED light, green LED light, and blue LED light. It will be understood that the examples in this specification are provided for illustrative purposes only. Any other color LED light may be selected to meet different emission requirements, and the selection is not limited to LED light; that is, other types of light may be used.

[0043] The light guide structure 2 further includes at least one light-shielding portion 22, and each pair of adjacent light guide strips 21 is separated by one light-shielding portion 22. The light-shielding portion 22 may include a light-absorbing material and / or a light-reflecting material, and as a result, when the light guide strips 21 transmit light, the light-shielding portion 22 can be used to prevent the light transmitted within the two adjacent light guide strips 21 from mixing. The light guide strips 21 may be made of glass fiber and / or polymer and may have a good light transmission effect.

[0044] For example, the light-reflecting material may be located on the surface of the light-shielding portion 22, which is close to the light guide strip 21. In this way, light can be more effectively restricted within the light guide strip 21, that is, light within the light guide strip 21 is less likely to be significantly attenuated during the transmission process.

[0045] For example, the light incident side and light emission side of the light guide strip 21 may be located at both ends of the light guide strip 21 in the direction of extension of the light guide strip 21, respectively.

[0046] For example, as shown in Figure 6, one of the light incident side and light emission side of the light guide strip 21 may be located at one end of the light guide strip in the direction of extension of the light guide strip, and the other may be located on the side of the light guide strip.

[0047] In the optical module 100 provided in this embodiment of the present application, light emitted by multiple sub-light sources 11 can each enter the corresponding light guide strip 21 through the light incidence side of the light guide strip 21, and then the light can be emitted from the light emission side of the light guide strip 21 to the light transmission unit 3. Furthermore, since the light shielding portion 22 is positioned between every two adjacent light guide strips 21, it is possible to prevent the light emitted from multiple sub-light sources 11 from mixing with the light guide structure, and as a result, the light emitted from multiple sub-light sources 11 can be emitted to different areas of the light transmission unit 3 via the corresponding light guide strips 21, allowing the light transmission unit 3 to simultaneously achieve the effect of multiple colors of light. Note that the light guide member in related art does not include the light shielding portion 22. Therefore, after the light guide structure 2 in this embodiment of the present application is replaced with a light guide member, the light emitted by the light source 1 is mixed with the light guide member. This makes the light emitted to the light transmission unit 3 uncontrollable, and a single gradient color is more likely to be formed. The optical module provided in this embodiment of the present application can adequately solve the aforementioned technical problems.

[0048] The following describes the light guide structure 2 provided in this embodiment of the present application. For ease of explanation, the direction in which the light guide strip 21 extends will be referred to as the first direction, and the direction in which the plurality of light guide strips 21 are arranged will be referred to as the second direction. Here, the first direction and the second direction may be linear, curved, or circumferential. The following describes in detail with reference to the accompanying drawings.

[0049] Please refer to Figure 6. In some embodiments, the light guide structure 2 includes a first region P1 and a second region P2 arranged in a first direction, with the first region P1 being closer to the light source than the second region P2. Figure 7 is a structural diagram of a combination of the light guide structure 2 and the light transmission unit 3 according to one embodiment of the present application. The portion of the light guide strip 21 that is located within the second region P2 includes a first surface 211 that is close to the light transmission unit 3. The portion of the light shielding portion 22 that is located within the second region P2 includes a second surface 221 that is close to the light transmission unit 3. The first surface 211 is closer to the light transmission unit 3 than the second surface 221.

[0050] In this embodiment, in the second region P2, the first surface 211 is positioned closer to the light-transmitting unit 3 than the second surface 221, that is, in the second region P2, the light guide strip 21 is positioned closer to the light-transmitting unit 3 than the light-shielding portion 22. As a result, light transmitted by multiple light guide strips 21 can reach different regions of the light-transmitting unit 3, and the gap regions between adjacent light guide strips 21 are used to generate a light mixing effect before light from the opposite side of adjacent light guide strips 21 enters the light-transmitting unit 3. This makes it possible to create transition colors in the transition regions between different colored light regions of the light-transmitting unit 3, thereby enhancing the visual effect.

[0051] The shape of the portion of the light guide strip 21 that is located within the first region P1, and the shape of the portion of the light shielding portion 22 that is located within the first region P1, are not limited in this application. For example, as shown in Figure 6, the portion of the light guide strip 21 that is located within the first region P1 and the portion of the light shielding portion 22 that is located within the first region P1 are plate-shaped with the same thickness.

[0052] For example, as shown in Figure 6, the first surface 211 of the light guide strip 21 may include a contact surface 2111, a first connecting surface 2112, and a second connecting surface 2113. Figure 8 is a structural diagram of another combination of the light guide structure 2 and the light transmission unit 3 according to one embodiment of the present application, and Figure 9 is a structural diagram of yet another combination of the light guide structure 2 and the light transmission unit 3 according to one embodiment of the present application. The contact surface 2111 is in contact with the light transmission unit 3 (not shown in Figure 6, but refer to the location of the light transmission unit 3 in Figure 5). The first connecting surface 2112 and the second connecting surface 2113 are located on either side of the contact surface 2111 in a second direction, with a gap between the first connecting surface 2112 and the light transmission unit 3, and a gap between the second connecting surface 2113 and the light transmission unit 3. The gap L1 between the first connection surface 2112 and the light-transmitting unit 3 gradually decreases in the direction approaching the contact surface 2111, and / or the gap L2 between the second connection surface 2113 and the light-transmitting unit 3 gradually decreases in the direction approaching the contact surface 2111.

[0053] In this example, the gap between the first connection surface 2112 and the light-transmitting unit 3 is set to gradually decrease in the direction approaching the contact surface 2111, so that the amount of light radiated from the first connection surface 2112 to the light-transmitting unit 3 can increase. The gap between the second connection surface 2113 and the light-transmitting unit 3 is set to gradually decrease in the direction approaching the contact surface 2111, so that the amount of light radiated from the second connection surface 2113 to the light-transmitting unit 3 can increase. Furthermore, the inclination of the first connection surface 2112 and the second connection surface 2113 may be further modified to adjust the light mixing effect of the light radiated from the first connection surface 2112 and the second connection surface 2113, and as a result, the transition light effect of the transition region between different colored light regions of the light-transmitting unit 3 may be further adjusted to enhance the visual effect.

[0054] For example, as shown in Figure 8, either the first connecting surface 2112 or the second connecting surface 2113 may be a flat surface. Another example is that, as shown in Figure 9, either the first connecting surface 2112 or the second connecting surface 2113 may be a curved surface.

[0055] In some embodiments, the light guide structure 2 may be a single, integrated structure, offering the advantages of convenient assembly and high reliability. In some other embodiments, the light guide strips 21 and light shielding portions 22 within the light guide structure 2 may be manufactured separately. For example, the light shielding portion 22 may be integrated with the housing 201, i.e., the light shielding portion 22 may be independently mounted to the housing 201 or directly formed integrally with the housing 201. In this way, multiple light guide strips 21 may be mounted separately, resulting in convenient maintenance and repair of any one of the light guide strips 21.

[0056] If the light guide structure 2 is a single integrated structure, for example, returning to Figure 6, additional connection parts 23 may be arranged around the light guide structure 2. In Figure 6, an example is used in which the upper, left, and right sides each include two connection parts. The specific location and quantity of the connection parts 23 are not limited in this application. In this example, since the connection parts 23 are arranged around the light guide structure 2, the light guide structure 2 can be easily attached and fixed to the housing 201.

[0057] For example, the connecting part 23 may be an adhesive, a connecting column, a screw column, a buckle, a slot, etc.

[0058] In some embodiments, please refer further to Figure 6. The first direction is a polylinear direction including, for example, a first linear extension within the first region P1 (indicated as the first secondary direction) and a second linear extension within the second region P2 (indicated as the second secondary direction). The second direction is linear and may be perpendicular to the first direction. In this case, please refer to Figures 7 to 9. In a direction perpendicular to both the second direction and the first secondary direction, the light guide structure 2 has a first side and a second side that are opposite to each other. The first side of the light guide structure 2 may be the light-emitting surface. In this case, the light-transmitting unit 3 is located on the first side of the light guide structure 2. Indeed, in another embodiment, the second side of the light guide structure 2 may be set as the light-emitting side. In this case, the second side of the light guide strip 21 may also have a first surface 211 projecting outward, and the light-transmitting unit 3 is located on the second side of the light guide structure 2. Alternatively, both the first and second sides of the light guide structure 2 may be designated as light-emitting sides, and light-transmitting units 3 may be arranged on both the first and second sides of the light guide structure 2.

[0059] In some other embodiments, as shown in Figure 10, Figure 10 is a structural diagram of yet another combination of a light guide structure 2 and a light transmission unit 3 according to one embodiment of the present application. In this case, the first direction is linear (perpendicular to the paper) and the second direction is circumferential. In this case, the light guide structure 2 may be a substantially solid cylindrical structure or a hollow cylindrical structure (Figure 10 uses a hollow cylindrical structure as an example for illustrative purposes). In this case, the light guide structure 2 may have an inner and outer side that are opposite to each other. As shown in Figure 10, the outer side of the light guide structure 2 may be the light-emitting side. In this case, the light transmission unit 3 is located on the outside of the light guide structure 2. Indeed, in another embodiment, the inner side of the light guide structure 2 may also be set as the light-emitting side. In this case, the inner side of the light guide strip 21 may also have a protruding first surface, and the light transmission unit 3 is located on the inside of the light guide structure 2. Alternatively, both the inner and outer sides of the light guide structure 2 may be light-emitting sides, and the light transmission unit 3 is located on both the inner and outer sides of the light guide structure 2.

[0060] In some other embodiments, the first direction is the curved direction (e.g., the arc direction or the elliptical arc direction), and the second direction is the circumferential direction. In this case, the light guide structure 2 is a substantially hollow spherical structure (not shown, e.g., a spherical structure or an ellipsoidal structure). In this case, the inside and outside of the light guide structure 2 may be opposite to each other. The outside of the light guide structure 2 may be the light-emitting side. In this case, the light-transmitting unit 3 is located outside the light guide structure 2.

[0061] The number of light-transmitting units 3 is not limited to this embodiment of the present application. For example, there may be one, two, or more light-transmitting units 3 located on any light-emitting side of the light-guiding structure 2.

[0062] The following describes the light transmission unit 3 provided in this embodiment of the present application in more detail.

[0063] In some embodiments, the light transmission unit 3 includes a light scatterer. Here, a light scatterer refers to a structure in which light incident on the light scatterer is reflected in multiple directions, thereby achieving a scattering effect.

[0064] For example, the light scatterer may be a structure containing a non-uniform medium. For instance, the scattering particles may be doped into a transparent substrate such as acrylic or glass, and the refractive index of the scattering particles may differ from that of the transparent substrate. In this way, when light is radiated onto a non-uniform medium (for example, radiated from a transparent substrate to scattering particles), the propagation direction can be changed to achieve a light scattering effect.

[0065] For example, the light scatterer may be a structure containing a homogeneous medium, such as a crystal. Even in this case, a scattering effect can be produced on the light.

[0066] In some of the embodiments described above, the light transmission unit 3 is configured to include a light scatterer, which can improve the lighting effect, making the effect more aesthetically pleasing and further enhancing the product's competitiveness.

[0067] In some embodiments, the acoustic reflection structure 311 is constructed on one side of the light transmission unit 3 that is away from the light guide structure 2 (see Figures 3, 7-10). In this case, the light transmission unit 3 may be located between the light guide structure 2 and the acoustic module 202, and the acoustic reflection structure 311 of the light transmission unit 3 is positioned toward the acoustic module 202 (the position of the acoustic module 202 is not shown in Figures 7-10), i.e., the acoustic reflection structure 311 is constructed on one side of the light transmission unit 3 that is facing the acoustic module 202. For example, the acoustic reflection structure 311 and the acoustic output surface of the acoustic module 202 may be positioned at a specific angle. For example, the angle range may be 10 to 80 degrees, and further, 30 to 60 degrees. For example, it may be 10, 20, 30, 40, 45, 50, 60, 70, 80 degrees, etc. In this embodiment, the light transmission unit 3 can achieve both a light effect and a sound adjustment effect. The acoustic reflection structure 311 may reflect acoustic waves, resulting in the scattering of acoustic waves in different directions, generating diffraction and altering the output sound quality effect.

[0068] For example, see Figures 4 and 5. In the electronic device 200, at least a portion of the area of ​​the second mounting position 220 may be positioned opposite to at least a portion of the area of ​​the first mounting position 210. In this way, when the light transmission unit 3 is located at the second mounting position 220, the light transmission unit 3 may be facing the acoustic module 202 located at the first mounting position 210, that is, the acoustic reflection structure 311 may be facing the acoustic module 202.

[0069] For example, the acoustic reflection structure 311 includes a plurality of first groove structures 31, the depths of which may be the same (i.e., as shown in Figures 7 to 10) or different (i.e., as shown in Figure 3). The depths of the plurality of first groove structures 31 may be adjusted to obtain different sound qualities. In this case, the shape of the acoustic reflection structure 311 is equivalent to that of a Schroeder diffuser, and acoustic waves are reflected by the plurality of first groove structures 31, resulting in the acoustic waves being scattered in different directions, generating diffraction, and changing the output sound quality effect.

[0070] For example, the multiple first groove structures 31 are strip-shaped, and the cross-sectional shape of the multiple first groove structures 31 may be rectangular, V-shaped, U-shaped, or W-shaped.

[0071] For some examples, please refer to Figures 7 to 10. The extension direction of the multiple first groove structures 31 may be the same as the extension direction of the multiple light guide strips 21, and the arrangement direction of the multiple first groove structures 31 is the same as the arrangement direction of the multiple light guide strips 21. In this case, one or more light guide strips 21 may be arranged on the back surface of one first groove structure 31, or one or more light guide strips 21 may be arranged on the back surface of the edge structure 32, lateral to the first groove structure 31 (not shown), or the same light guide strips 21 may be arranged on the mutually adjacent back surfaces of the first groove structure 31 and the edge structure 32 (not shown). Here, the back surface means one side of the light transmission unit 3 that is closer to the light guide structure 2. In this example, different color light effects can be formed at different positions of the first groove structures 31 and different positions of the edge structure 32.

[0072] For example, the widths of the different first groove structures 31 in the second direction may be the same or different. Similarly, the widths of the different edge structures 32 in the second direction may be the same or different. By reducing the width of the first groove structure 31 in the second direction and the width of the edge structure 32 in the second direction, a mixing effect of two or more types of light can be achieved. By increasing the width of the first groove structure 31 in the second direction and the width of the edge structure 32 in the second direction, the mixing effect of adjacent light can be reduced. For example, a dark region may be formed in the transition region of the light transmission unit 3.

[0073] In some examples, the orthogonal projection of the first groove structure 31 onto the reference plane at least partially overlaps with the orthogonal projection of the light guide strip 21 onto the reference plane, where the reference plane is the plane on which the first and second directions are located. It will be understood that the thickness of the light-transmitting unit 3 at the location of the first groove structure 31 is thinner than the thickness of the light-transmitting unit 3 at the location of the edge structure 32. In this example, the orthogonal projection of the first groove structure 31 onto the reference plane is set to at least partially overlap with the orthogonal projection of the light guide strip 21 onto the reference plane, and as a result, a light effect of higher luminance can be generated at the location of the first groove structure 31, a light effect of different colors can be generated at different locations of the first groove structure 31, and a darker transition light effect can be generated at the location of the edge structure 32. Thus, the light-transmitting unit 3 can simultaneously realize the light effect of multiple colors, and a better transition color can be formed between two adjacent colors of light.

[0074] In some embodiments, please refer to Figure 11. Figure 11 is a structural diagram of yet another combination of a light guide structure 2 and a light transmission unit 3 according to one embodiment of the present application. The second groove structure 33 is located on a surface of the light transmission unit 3 that is close to the light guide structure 2, and at least a portion of the light guide strip 21 extends into the second groove structure 33. In embodiments shown in Figures 8 to 10, the second groove structure 33 may also be additionally located on the light transmission unit 3, and it will be understood that details are not repeated here.

[0075] For example, there may be one or more second groove structures 33. At least a portion of one light guide strip 21 may extend into one second groove structure 33, or at least a portion of two or more light guide strips 21 may extend into the same second groove structure 33.

[0076] For example, the light guide strip 21 and the second groove structure 33 may be fitted in an interference fit or a clearance fit.

[0077] For example, the position of the second groove structure 33 may be opposite to the position of the first groove structure 31 (i.e., as shown in Figure 11), or opposite to the position of the aforementioned edge structure 32 (not shown).

[0078] For example, the shape of the second groove structure 33 may further match the shape of the light guide strip 21 (e.g., the shape of the first surface of the light guide strip), and as a result, the contact area between the light guide strip 21 and the light transmission unit 3 may be larger.

[0079] In this embodiment, the second groove structure 33 is positioned on the surface of the light transmission unit 3 that is close to the light guide structure 2, and as a result, the second groove structure 33 can be used to provide positioning and support functions for the light guide strip 21. In addition, this increases the amount of light emitted from the light guide strip 21 to the light transmission unit 3, improving the luminescence brightness of the light transmission unit 3.

[0080] In some embodiments, please refer to Figure 12. Figure 12 is a structural diagram of yet another combination of a light guide structure 2 and a light transmission unit 3 according to one embodiment of the present application. The surface of the light transmission unit 3 that is close to the light guide structure 2 includes a barrier layer 5, the numerical range of transmittance of the barrier layer 5 being 30% to 60% (including 30% and 60%). In embodiments shown in Figures 8 to 11, the barrier layer 5 may also be additionally arranged, and it will be understood that the details are not repeated here.

[0081] In this embodiment, if the transmittance of the barrier layer 5 is close to or equal to 30%, the barrier layer 5 can have a good shielding effect on the light guide structure 2. That is, when the light guide structure 2 is dark, it is difficult for the human eye to see the light guide structure from the other side of the light transmission unit 3. However, when the light guide structure 2 is bright, the light from the light guide structure 2 can still be radiated to the light transmission unit 3 through the barrier layer 5. Also, if the transmittance of the barrier layer 5 is close to or equal to 60%, the barrier layer 5 can have a certain degree of shielding effect on the light guide structure 2. In this case, when the light guide structure 2 is bright, more light from the light guide structure 2 can be radiated to the light transmission unit 3 through the barrier layer.

[0082] For example, the numerical range of the transmittance of the barrier layer 5 may be 40% to 45% (including 40% and 45%). In this case, the barrier layer 5 can have a good shielding effect on the light guide structure 2, and when the light guide structure 2 is in a bright state, more light from the light guide structure 2 can be radiated to the light transmission unit 3 through the barrier layer 5, resulting in an improved lighting effect.

[0083] The foregoing description is merely a specific embodiment of the present application and is not intended to limit the scope of protection of this application. Any modification or substitution that is readily conceivable by a person skilled in the art within the scope of the art disclosed in this application shall fall within the scope of protection of this application. Accordingly, the scope of protection of this application shall be subject to the scope of protection of the claims. [Explanation of symbols]
