[0057] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0058] like Figures 1 to 12 As shown, the utility model is an anti-cross-light bone conduction earphone structure, including a first ear hook component 1 and a second ear hook component 2 respectively hung on the left ear and the right ear, and a rear hanging component 3 arranged between the first ear hook component 1 and the second ear hook component 2, the first ear hook component 1 and the second ear hook component 2 are both provided with a light guide 4, the light guide 4 is exposed from the outside of the first ear hook component 1 and the second ear hook component 2, the light guide 4 is provided with a light emitting portion 41, and the light emitting portion 41 is provided in plurality and is arranged at intervals along the length direction of the light guide 4.

[0059] The two ends of the rear hanging component 3 are respectively connected to the first ear hanging component 1 and the second ear hanging component 2. The end of the first ear hanging component 1 away from the rear hanging component 3 is electrically connected to a core module, and the end of the second ear hanging component 2 away from the rear hanging component 3 is electrically connected to another core module. Further, the rear hanging component 3 can be set in a curved shape for winding around the back of the user's head. The first ear hanging component 1 and the second ear hanging component 2 can also be set in a curved shape for hanging on the left ear and the right ear of the user, thereby facilitating the wearing requirements of the bone conduction earphone. The two core modules are used to convert the electrical signal into mechanical vibration so that the user can hear the sound through the bone conduction earphone. The light guide 4 exposes the outside of the first ear hanging component 1 and the second ear hanging component 2, which can increase the light emitting area and improve the indication effect, so that the user can obtain a good lighting effect during use. In addition, the light emitting portion 41 is provided with a plurality of light emitting portions 41 and is arranged at intervals along the length direction of the light guide 4, presenting a segmented light guiding effect, so that the light guide 4 has a significant light focusing performance. The utility model has a large luminous area, which effectively makes the emitted light uniform and soft, effectively avoids the occurrence of scattered light, light leakage, and light stringing, and enhances the user experience.

[0060] The first ear hook component 1 and the second ear hook component 2 of the present embodiment are both provided with a controller 5 and a light source 6 installed on the controller 5, the light guide 4 is arranged on the light source 6, the light guide 4 includes a light guiding portion 42 and a light receiving portion 43 recessed in the light guiding portion 42, the light receiving portion 43 is arranged opposite to the light source 6 and is used to receive the light emitted by the light source 6, the light guiding portion 42 is used to scatter and distribute the light to the light emitting portion 41, and a plurality of light emitting portions 41 are protruding from the light guiding portion 42 and are used to emit light guided by the light guiding portion 42. Specifically, as a preference, three light emitting parts 41 are provided, and three light receiving parts 43 are provided. The three light emitting parts 41 are convexly arranged on the top of the light guiding part 42, and the three light receiving parts 43 are concavely arranged on the bottom of the light guiding part 42. The three light emitting parts 41 and the three light receiving parts 43 are respectively arranged opposite to each other and are arranged at intervals along the length direction of the light guiding part 42. The position of each light emitting part 41 is arranged in a one-to-one correspondence with the position of each light receiving part 43. The light source 6 is placed below the light receiving part 43 and illuminates the light receiving part 43. The light-guiding portion 42 guides the light to the corresponding light-emitting portion 41, and then emits the light through the light-emitting portion 41. Since the light-emitting portion 41 is divided into multiple sections, the light-receiving portion 43 is recessed to form a U-shaped baffle wall, and the light is scattered to the corresponding light-emitting portion 41 through the U-shaped baffle wall. The light can be emitted together or the light sources 6 at different positions can be used to control the light-emitting effects of sections at different positions. Since the three light-emitting portions 41 are separated from each other, accidental light crosstalk can be effectively prevented when a certain section emits light. The structure is compact and occupies little space, which improves the user experience.

[0061] The light emitting portion 41 of this embodiment is prism-shaped, and a gap 44 is provided between two adjacent light emitting portions 41, and the outer edges of the light emitting portions 41 are all provided with chamfers 45. Specifically, the gap 44 is provided between two adjacent light emitting portions 41, which helps the multiple light emitting portions 41 to work independently without affecting each other, and effectively avoids the accidental cross-lighting. The prism-shaped light emitting portion 41 has a large light emitting area, evenly disperses and propagates light, and the light emitting point is not visible, making the light softer, reducing brightness loss, and having a good light emitting effect. The chamfer 45 prevents the corners of the light emitting portion 41 from scratching the external parts when the light emitting portion 41 is assembled and connected to the external parts, and plays a protective role on the external parts.

[0062] The first ear hook assembly 1 of the present embodiment includes a shell 11 and a cover body 12 which is covered and mounted on the shell 11. The controller 5 is mounted between the cover body 12 and the shell 11. A groove 13 is provided in the shell 11. The groove 13 is recessed from the surface of the shell 11.

A limit block 15 is provided between two adjacent through grooves 14. The light guide 4 is stopped and abutted against the limit block 15 through a gap 44. Specifically, the groove 13 is recessed from the surface of the shell 11 and has an opening facing upward, so that the light guide 4 can be installed in the groove 13 from top to bottom. There are three through grooves 14, which are spaced apart along the length direction of the shell 11. A limit block 15 is provided between two adjacent through grooves 14. The light emitting portion 41 is stopped and abutted against the limit block 15 through the gap 44, so that the three light emitting portions 41 are respectively passed through and fixed in the three through grooves 14, thereby causing the inner groove wall of the gap 44 to stop and abut against the outer wall of the limit block 15 to ensure that the outer end face of the light emitting portion 41 is flush with the outer side face of the shell 11, which not only plays a good role in fixing the position of the light guide 4, but also helps the light guide 4 to show a high-definition and significant indicating effect.

[0063] The cover body 12 of this embodiment is provided with a button assembly 16, which includes a button plate 161 and a button cap 162 arranged on the button plate 161, the button cap 162 is provided with a button column 163, and the button column 163 protrudes from the outer wall of the button cap 162, the button plate 161 is provided with a pressing column 164, and the pressing column 164 protrudes from the surface of the button plate 161, and the pressing column 164 is provided with a pressing groove 165 for accommodating the button column 163, and the inner groove wall of the pressing groove 165 blocks and resists the button column 163. Specifically, the key panel 161 is sleeved on the inner wall of the cover body 12, and two key caps 162 are provided and protrude from the cover body 12 at intervals. The key caps 162 are correspondingly inserted into the pressing groove 165 through the key column 163, so that the inner groove wall of the pressing groove 165 stops and abuts against the outer wall of the key column 163. The connection is stable and reliable. The user only needs to press the key cap 162 to transmit the pressing force to the controller 5 through the key cap 162, thereby triggering the controller 5 to control the use of the bone conduction headset. The operation is simple and convenient.

[0064] In this embodiment, a plurality of button columns 163, pressing columns 164, and pressing grooves 165 are provided respectively.

When the button cap 162 approaches the three button columns 163 respectively, the pressing grooves 165 and the pressing columns 164 are pressed. The pressing column 164 makes the three button columns 163 aligned and inserted in the three pressing grooves 165 respectively, which is conducive to the close connection between the button column 163 and the pressing groove 165, thereby ensuring that the button cap 162 can achieve the purpose of force balance when pressed at each point. In addition, the button cap 162 is made of high-elastic silicone material to avoid abnormal noise during the pressing process, with good silencing effect and high consistency of force feedback. The high force balance and good force feedback of the button cap 162 are combined to improve the control feel of the button cap 162 and provide a good user experience.

[0067] The rear hanging assembly 3 of this embodiment includes a rear hanging 31 and a connecting end 32 arranged on the rear hanging 31, the connecting end 32 is provided with a protrusion 33, the protrusion 33 is protruded from the end surface of the connecting end 32, the protrusion 33 is provided with a limiting rib 34, the limiting rib 34 protrudes from the surface of the protrusion 33, the shell 11 is provided with a positioning groove 18, the positioning groove 18 is recessed from the inner wall of the shell 11, and the limiting rib 34 is slidably accommodated in the positioning groove 18. Specifically, the back hanger 31, as an important component of the bone conduction earphone, can be wrapped around and clamped on the back of the user's head for use. Two connecting ends 32 are provided and are respectively installed at the two ends of the back hanger 31. The protrusion 33 is protruded from the end face of the connecting end 32. The protrusion 33 is respectively inserted into the first ear hook component 1 and the second ear hook component 2 to avoid incorrect installation of the back hanger 31 during the assembly process.

[0072] Fig.13 A cross-sectional diagram of a light guide structure provided in an embodiment of the present application, Fig.14 for Fig.13 Magnified view of area A in the middle.

[0073] In the examples of this application, see Fig.13 and Fig.14 As shown, the shell 11 and the light guide 4 can be the same plastic part. For example, the molding materials of the shell 11 and the light guide 4 can be the same material with different physical properties, and the shell 11 and the light guide 4 can be connected by a nesting method. The physical properties refer to the color, transmittance and other properties of the material. For example, the shell 11 and the light guide 4 can be made of the same material but different colors and transmittances. For example, the shell 11 and the light guide 4 can both be made of polyamide (Polyamide; PA for short), but the physical properties of the polyurethane material forming the shell 11 and the polyurethane material forming the light guide 4 are different. For example, according to the structural requirements and functional requirements of the shell 11 and the light guide 4, the polyurethane materials forming the shell 11 and the light guide 4 can have different colors and transmittances to meet the special requirements of the shell 11 and the light guide 4.

[0074] The injection molding process, also known as secondary injection molding, is a special plastic molding process. After a certain plastic raw material is molded in a primary plastic mold, the molded parts are taken out and placed in a secondary molding mold to be injected with the same or another plastic material again.

[0075] The structure of injection molding using the beer-jacketing process can make the shell 11 and the light guide 4 tightly combined. Moreover, the shell 11 and the light guide 4 are made of the same material, so the shell 11 and the light guide 4 can be fused with each other, making the shell 11 and the light guide 4 more tightly combined, which can effectively improve the sealing between the shell 11 and the light guide 4.

[0076] Continue to see Fig.14 As shown, the light guide structure may further include a cladding layer 7, which may be covered on the outside of the shell 11, and a portion of the light guide 4 protruding from the shell 11 may be exposed outside the cladding layer 7, and the cladding layer 7 may be connected to the shell 11 and the light guide 4 by a beer-coating process.

[0077] For example, the shell 11 and the light guide 4 can be first injection molded together through a nesting process to connect the shell 11 and the light guide 4, so that the shell 11 and the light guide 4 become an integral injection molded structure, and then the injection molded structure formed by the shell 11 and the light guide 4 is placed in another mold, and then the material forming the coating layer 7 is injected into the mold to connect the coating layer 7 and the injection molded structure, thereby completing the injection molding operation of the coating layer 7, the shell 11 and the light guide 4 as a whole.

[0078] The cladding layer 7 , the shell 11 and the light guide 4 are formed by a laminating process, so that the cladding layer 7 , the shell 11 and the light guide 4 can be closely fitted, and the sealing between the cladding layer 7 and the light guide 4 can be effectively improved.

[0079] In the present application, the housing 11 and the light guide 4 are made of the same material with different physical properties and are made by a nesting process. The same materials can fit more closely together in the nesting process, so that the housing 11 and the light guide 4 can be tightly combined, which can effectively improve the sealing between the light guide 4 and the housing 11 and improve the waterproofness of the earphone. Moreover, by connecting the coating layer 7 with the housing 11 and the light guide 4 by a nesting process, the coating layer 7 and the light guide 4 can be tightly combined, so that the coating layer 7 and the light guide 4 have better sealing, thereby effectively improving the sealing and waterproofness of the earphone.

[0080] Fig.15 A schematic structural diagram of a shell provided in an embodiment of the present application.

[0081] See also Fig.14 and Fig.15 As shown, a glue groove 111 may be provided on the housing 11, and the glue groove 111 may be located between the housing 11 and the light guide 4, and a sealant may be provided in the glue groove 111. The sealant may fill the pores or gaps between the housing 11 and the light guide 4, and may provide a better sealing effect between the housing 11 and the light guide 4. The sealing between the housing 11 and the light guide 4 may be effectively improved, and the waterproofness between the housing 11 and the light guide 4 may be enhanced.

[0082] Continue to see Fig.14 and Fig.15 As shown, the glue groove 111 can be located on the side of the housing 11 facing the coating layer 7. In other words, it can be understood that the glue groove 111 is located on the outside of the housing 11 and is coated by the coating layer 7. For example, after the housing 11 and the light guide 4 are injection molded, the glue groove 111 between the housing 11 and the light guide 4 can be filled with sealant first, and then the coating layer 7 is injection molded. In this way, the coating layer 7 can coat the sealant inside, so that the sealant inside the coating layer 7 provides a seal between the housing 11 and the light guide 4.

[0083] This can effectively reduce or prevent the sealant from falling off, which helps to improve the stability and reliability of the sealant seal. In addition, the sealant is arranged in the coating layer 7, which can also improve the concealment of the sealant and help improve the aesthetics of the earphone exterior.

[0084] The housing 11 may be made of a non-light-absorbing and non-transparent material, for example, the molding material of the housing 11 may be made of a non-light-absorbing and non-transparent material. For example, the molding material of the housing 11 may be made of a light-colored color such as white or yellow, which does not absorb light. This can prevent the light emitted by the light source 4 from being absorbed by the housing 11, and can allow all the light emitted by the light source 4 to be projected into the light guide 4 and projected outward through the light guide 4. This can effectively increase the brightness of the light emitted by the light guide 4 and improve the light effect displayed by the light guide 4.

[0085] In addition, by making the shell 11 of opaque material, the light crosstalk caused by the light being projected outward through the shell 11 can be reduced or avoided, thereby affecting the overall lighting effect of the earphone, which helps to improve the overall lighting effect of the earphone.

[0086] The light guide 4 can be a transparent plastic part. For example, the molding material of the light guide 4 can be a transparent material. For example, the transparency of the molding material of the light guide 4 can be greater than 80%. This can effectively improve the light transmittance of the light guide 4, so that the light emitted by the light source 4 can be smoothly projected outward from the light guide 4, which can effectively improve the luminous effect of the light guide 4.

[0087] The coating layer 7 can be a silicone layer, that is, the molding material of the coating layer 7 can be silicone. The silicone material is relatively soft and has a certain elasticity. It can provide elastic buffering on the outside of the earphone shell 11, which can reduce or avoid damage to the earphone due to bumps during use, which is beneficial to improve the overall protection of the earphone.

[0088] Moreover, the silicone material has a good touch and can provide better comfort when the user wears it, helping to improve the user's wearing experience.
