Description

Technical Field

[0001] This application relates to the field of audio playback technology, and more particularly to a pair of headphones. Background Technology

[0002] With the widespread use of smartphones, tablets and other electronic devices, headphones, as electronic devices that connect to mobile terminals and receive and transmit audio signals, are also constantly being updated and upgraded. While pursuing better sound quality, people are also placing higher demands on the stability of headphone wearing.

[0003] In related technologies, for earphones such as True Wireless Stereo (TWS), when worn in the ear, they are mainly secured by the friction of the ear tips to prevent them from falling out of the ear.

[0004] However, in actual use, users' heads and ears often make various movements such as turning or shaking their heads, which can cause the earphones to slip out of the ear and make it difficult to ensure the stability of the fit. Summary of the Invention

[0005] This application provides an earphone that improves the stability of earphone wearing, prevents the earphone from slipping out of the ear, and enhances the user experience.

[0006] According to one aspect of this application, an earphone is provided, comprising:

[0007] The body includes a main unit and a mouthpiece, wherein the mouthpiece is axially inclined relative to the main unit;

[0008] The earphone cover includes an insertion part fitted onto the sound nozzle and a support part fitted onto the main unit. The extension direction of the support part is opposite to the extension direction of the insertion part and has a certain angle. When the earphone is in the wearing state, the insertion part is configured to be inserted into the ear canal, and the support part is configured to abut against the antihelix.

[0009] There is a first gap between the support and the host, which provides space for the support to avoid deformation.

[0010] In one possible design, the thickness of the support portion is greater than the thickness of the insertion portion.

[0011] In one possible design, the earphone cover further includes a contact portion extending along the insertion portion to the support portion, the contact portion being used to connect the insertion portion and the support portion, and the contact portion being configured to contact the inner ear canal when the earphone is in the wearing state.

[0012] In one possible design, the support portion includes a first curved surface disposed opposite to the insertion portion along a first direction, the first curved surface extending from the connection point with the contact portion along a second direction perpendicular to the first direction, and the radius of curvature of the first curved surface gradually decreasing along the second direction.

[0013] In one possible design, the support portion further includes a second curved surface disposed opposite to the first curved surface along a second direction, the radius of curvature of the second curved surface being greater than that of the first curved surface; the second curved surface gradually approaches the first curved surface from one end connected to the first curved surface to one end near the insertion portion, so as to form a clearance portion at the connection between the second curved surface and the contact portion, wherein when the earphone is in the wearing state, the clearance portion is used to avoid the helix foot of the ear.

[0014] In one possible design, the inner wall of the insertion part is in close contact with the peripheral wall of the mouthpiece, the outer side of the insertion part has an umbrella-shaped part that extends in an insertion direction away from the insertion part, and the umbrella-shaped part has a second gap with the peripheral wall of the insertion part.

[0015] In one possible design, the body further includes a cover and a charging protrusion, the cover and the charging protrusion being connected to the host, and at least one of the cover and the charging protrusion being exposed outside the earphone cover.

[0016] In one possible design, the earphone cover has a first opening located at the cover, the diameter of the first opening being smaller than the diameter of the cover.

[0017] And / or,

[0018] The earphone cover has a second opening located at the charging protrusion, and the diameter of the second opening is smaller than the diameter of the charging protrusion.

[0019] In one possible design, the charging protrusion is provided with a charging cover, which is disposed on the charging protrusion and detachably connected to the charging protrusion. The diameter of the charging cover is larger than the diameter of the charging protrusion, so as to form a first groove between the charging cover and the body. The edge of the second opening is embedded in the first groove.

[0020] In one possible design, the charging cover and the charging boss are sealed together.

[0021] In one possible design, the inner side of the earphone cover is provided with a limiting member, which is located on the side of the second opening near the insertion part. The limiting member is embedded in the first groove and is used to prevent the edge of the second opening from disengaging from the first groove.

[0022] In one possible design, the earphone cover has a first opening located at the cover; the cover has a groove on its peripheral wall, the first opening has a protrusion, and the protrusion is fitted into the second groove;

[0023] And / or, the earphone cover has a second opening located at the charging protrusion; the peripheral wall of the charging protrusion has a first groove, and the edge of the second opening has a protrusion that is embedded in the first groove.

[0024] In this embodiment, an earphone cover is wrapped around the earphone body, with the insertion part of the earphone cover inserted into the mouthpiece of the main body, and the support part fitted onto the main body. The insertion part and the support part extend in opposite directions at a certain angle. When the earphone is worn, the insertion part is inserted into the ear canal, while the support part rests against the antihelix of the ear, creating an interactive resisting force between them. The support part effectively holds the insertion part against the ear canal. Furthermore, a first gap is provided between the support part and the main body. This gap provides space for the support part to move or change shape, improving wearing comfort. Compared to existing technologies, this method stably holds the earphone against the ear canal, improving wearing stability and preventing the earphone from slipping out of the ear, thus enhancing the user experience.

[0049] Reference Figure 1 As shown, Figure 1 This is a schematic diagram of the human ear's outline. To facilitate the explanation of the shape, structure, and wearing method of the earphones provided in this embodiment of the invention, the human ear auricle mainly includes the tragus 1, antitragus 2, concha cavity 3, antihelix 4, helix 5, and cymba conchae 6; wherein, the tragus 1 and antitragus 2 have an intertragusal incision 7, and the helix 5 has helix crus 8. Within the internal cavity of the auricle, the portion below the helix crus 8 forms the concha cavity 3, and the portion above the helix crus forms the cymba conchae 6; the concha cavity 3 includes a medial concha 9, which is typically located medial to the antitragus 2.

[0050] Reference Figures 2-4 As shown, Figure 2 This is a schematic diagram of the overall structure of the headphones provided in the embodiments of this application. Figure 3 It is along Figure 2 Cross-sectional view of line AA in the middle. Figure 4 This is a schematic diagram of the earphone's interaction with the human ear when it is in a wearing state, according to an embodiment of this application. The earphone provided in this embodiment includes:

[0051] The main body 10 includes a main unit 11 and a mouthpiece 12, with the mouthpiece 12 being axially tilted relative to the main unit 11.

[0052] Reference Figure 3 As shown, the host 11 can refer to a part equipped with audio signal reception and conversion. The specific shape of the host 11 can be cylindrical or an approximately cylindrical elliptical cylinder. The axis of the host 11 is specifically the axis of the cylinder or the direction perpendicular to the plane where the major axis and minor axis intersect. Figure 3 As an example, the axis of the host 11 can be... Figure 3 The vertical direction. Of course, it should be noted that the axis of the main unit 11 is not fixed in a certain direction. The axis of the main unit 11 has different directions when the main unit 11 is in different states. For example, when the headphones are in the wearing state, the axis of the main unit 11 can be perpendicular to or approximately perpendicular to the ear canal.

[0053] In this embodiment, the mouthpiece 12 is tilted relative to the axis of the host 11, that is, the extension direction of the mouthpiece 12 has a certain angle with the axis of the host 11, so that the mouthpiece 12 can be easily extended into the ear canal.

[0054] The earphone cover 20 includes an insertion part 21 fitted onto the mouthpiece 12 and a support part 22 fitted onto the main unit 11. The extension direction of the support part 22 is opposite to the extension direction of the insertion part 21 and has a certain angle. When the earphone is in the wearing state, the insertion part 21 is configured to be inserted into the ear canal, and the support part 22 is configured to abut against the antihelix.

[0055] Specifically, in this embodiment, the earphone cover 20 can be a soft silicone cover.

[0056] In specific configurations, the earphone cover 20 can completely cover the outside of the main body 10, enveloping the entire main body 10. Of course, in some possible examples, the earphone cover 20 can also partially cover the main body 10, such as only covering the mouthpiece 12, or covering the mouthpiece 12 and then partially covering the main body 11.

[0057] Reference Figure 3 As shown, the extending direction of the insertion part 21 can refer to Figure 3 Specifically, as indicated by the arrow x, the extension direction of the insertion part 21 is consistent with the extension direction of the mouthpiece 12. That is, the insertion part 21 extends radially from the side of the main unit 11 where the mouthpiece 12 is located, and its radial extension path is consistent with that of the mouthpiece 12, meaning it has a certain deflection along the axial direction of the main unit 11, thus facilitating the insertion part 21 to be fitted onto the mouthpiece 12. The extension direction of the support part 22 can refer to... Figure 3 As indicated by the arrow y, the extension direction of the support portion 22 can specifically be consistent with the radial direction of the main unit 11. Specifically, it can extend radially from the side wall of the main unit 11 away from the mouthpiece 12 towards the side away from the mouthpiece 12; thus, the support portion 22 is opposite to the insertion portion 21. Figure 3 As shown, the extension direction of the insertion part 21 forms an obtuse angle with the extension direction of the support part 22. This allows it to adapt to the angle between the ear canal and the ear cavity, making the design ergonomic and providing greater comfort when the user wears it.

[0058] Reference Figure 4 As shown, during actual wear, the insertion part 21 can be inserted into the ear canal, while the support part 22 abuts against the antihelix of the ear. In this way, since the extension directions of the support part 22 and the insertion part 21 are set opposite to each other, the abutting force between the support part 22 and the antihelix will be transmitted to the insertion part 21, making the insertion part 21 tend to go deeper into the ear canal. This can prevent the insertion part 21 from slipping out of the ear canal, improve the stability of wearing the headphones, and enhance the user experience.

[0059] In this embodiment of the application, a first gap 223 is provided between the support part 22 and the host 11, and the first gap 233 is used to provide deformation avoidance space for the support part 22.

[0060] In the specific design, the inner side of the support part 22 can be processed by the glue removal process to form the first gap 223 between it and the main unit 11.

[0061] In this way, the first gap 223 between the support part 22 and the main unit 11 can form an air bladder. In some application scenarios, when the human ear moves or is squeezed (such as when the head moves while sleeping), the air bladder formed by the first gap 223 can provide a certain amount of clearance space, so that the support part 22 will not exert excessive pressure on the concha cavity, thereby improving the wearing comfort. In addition, due to the existence of the first gap 223, the support part 22 can still stably press against the concha cavity when the human ear moves or is squeezed, which can prevent the earphone from falling off due to the compression or movement of the ear, thereby improving the stability of the earphone wearing.

[0062] Optional, refer to Figure 3 As shown in the embodiment of this application, the thickness of the support portion 22 is greater than the thickness of the insertion portion 21. Here, thickness refers to the thickness of the earphone sleeve adhesive layer.

[0063] In the specific design, the thickness of the insertion part 21 can be designed to be the same as or approximately the same as the uniform thickness of the entire earphone cover 20, while the thickness of the support part 22 can be designed to be greater than the uniform thickness of the entire earphone cover 20. In this way, the relatively thick support part 22 is less likely to be deformed by the movement of the ear (such as the pressure between the ear and the pillow when sleeping, or the pressure between the ear and the helmet when cycling), that is, the support part 22 can provide more stable support and improve the stability of wearing the earphone.

[0064] Optional, refer to Figure 2 and Figure 4 As shown in the embodiment of this application, the earphone cover 20 also includes a contact portion 23, which extends along the insertion portion 21 to the support portion 22. The contact portion 23 is used to connect the insertion portion 21 and the support portion 22. When the earphone is in the wearing state, the contact portion 23 is configured to contact the inner ear cavity.

[0065] Reference Figure 2 As shown, the contact portion 23 can be mainly connected between the insertion portion 21 and the support portion 22. For example, the contact portion 23 can be a silicone ring, which is fitted onto the outer periphery of the main unit 11, and the insertion portion 21 and the support portion 22 are respectively connected to the silicone ring. It should be noted that since the mouthpiece 12 needs to extend from the main unit 11, the silicone ring can be provided with an opening on one side of the mouthpiece 12, that is, the side wall of the silicone ring can be provided with an opening or hole through which the mouthpiece 12 passes, so as to facilitate the insertion of the mouthpiece 12 into the insertion portion 21.

[0066] Reference Figure 4 As shown, when worn, the contact part 23 contacts the inner ear cavity of the ear canal. In this way, the inner ear cavity can provide support and an inward fixing force for the entire headphone, which can improve the stability of the headphone and enhance the user experience.

[0067] Optional, refer to Figure 5 As shown, Figure 5 This is a structural schematic diagram of the earphone provided in another perspective according to an embodiment of this application. In this embodiment, the support portion 22 includes a first curved surface 221 disposed opposite to the insertion portion 21 along a first direction. The first curved surface 221 extends from the connection point with the contact portion 23 along a second direction perpendicular to the first direction, and the radius of curvature of the first curved surface 221 gradually decreases along the second direction.

[0068] Specifically, the first direction can refer to Figure 5 The direction indicated by the dashed line b, the second direction could refer to... Figure 5 The direction indicated by the dashed line c. It should be noted that the first direction is not fixed to a certain direction, and its specific direction can be determined by the usage or wearing state of the headphones. For example, the first direction can refer to the direction of the line connecting the support part 22 and the insertion part 21. The first curved surface 221 can be an overall arc structure, and the curvature of its arc gradually increases along the extension direction of the first curved surface 221, that is, its radius of curvature gradually decreases.

[0069] When the user wears the headphones, the support part 22 rests against the antihelix. By setting the radius of curvature of the first curved surface 221 to gradually decrease, it can adapt to the shape change of the antihelix, which is more ergonomic and can improve the user's wearing comfort.

[0070] Optional, continue to refer to Figure 5 As shown in the embodiment of this application, the support portion 22 further includes a second curved surface 222 disposed opposite to the first curved surface 221 along the second direction, and the radius of curvature of the second curved surface 222 is greater than the radius of curvature of the first curved surface 221;

[0071] The second curved surface 222 gradually approaches the first curved surface 221 from the end connected to the first curved surface 221 to the end near the insertion part 21, so as to form a clearance part 24 at the connection between the second curved surface 222 and the contact part 23. When the earphone is in the wearing state, the clearance part 24 is used to avoid the helix foot of the ear.

[0072] Specifically, refer to Figure 5 As shown in the embodiment of this application, the second curved surface 222 may gradually approach the first curved surface 221 along the second direction as it extends along the first direction. Figure 5 In this design, the second curved surface 222 can be considered to be slightly tilted downwards. This creates a recessed clearance 24 at the point where the second curved surface 222 connects to the contact portion 23 (e.g., the aforementioned silicone ring). Thus, when the earphone is worn, the recessed clearance 24 can avoid the helix of the ear.

[0073] This embodiment of the application sets the curved extension shape of the second curved surface 222, making its radius of curvature larger than that of the first curved surface 221, while extending the second curved surface 222 closer to the first curved surface 221, so that a clearance portion 24 is formed at the connection between the second curved surface 222 and the contact portion 23. In this way, when the headphones are worn, the clearance portion 24 can avoid the helix of the ear, meaning the contact portion 23 will not contact the helix, thus avoiding pressure on the helix, conforming to ergonomic design, and improving the comfort of wearing the headphones.

[0074] Optional, continue to refer to Figure 3 As shown in the embodiment of this application, there is a second gap 211 between the insertion part 21 and the mouthpiece 12, and the peripheral wall of the insertion part 21 is radially raised relative to the mouthpiece 12.

[0075] Specifically, the second gap 211 can also be formed by removing adhesive; in specific settings, refer to... Figure 2 As shown, the peripheral wall of the insertable part 21 first extends a certain distance away from the axial direction of the mouthpiece 12, and then bends and extends towards the axial direction of the mouthpiece 12, thereby forming a second gap 211.

[0076] Among them, the peripheral wall of the insertion part 21 is radially relative to the mouthpiece 12 ( Figure 3 The insertion part 21 has a raised structure in the direction shown by d. That is, at the second gap 211, the peripheral wall of the insertion part 21 has a protruding structure relative to other positions. This ensures that the peripheral wall of the insertion part 21 is in close contact with the ear canal, thereby improving the noise reduction effect.

[0077] Thus, after the insertion part 21 is inserted into the ear canal, the presence of the second gap 211 provides a certain amount of clearance for the insertion part 21, allowing the insertion part 21 to fully contact the inner wall of the ear canal through its elasticity, thereby improving the noise reduction effect. In addition, when the ear is compressed (such as when the ear is compressed during sleep as mentioned above), the second gap 211 provides deformation space for the insertion part 21, allowing the insertion part 21 to better adapt to changes in the shape of the ear canal and improve wearing comfort.

[0078] Optional, refer to Figure 3 As shown in the embodiment of this application, the insertion part 21 is provided with a sleeve 212, and the sleeve 212 is interference-fitted with the mouthpiece 12.

[0079] Specifically, in this embodiment, the diameter of the sleeve 212 is slightly smaller than the diameter of the mouthpiece 12. In this way, after the sleeve 212 is fitted onto the mouthpiece 12, the sleeve 212 can be tightly fitted to the outer wall of the mouthpiece 12, and the sound signal can be completely exported from the sleeve 212, avoiding sound leakage within the earphone sleeve 20, and improving the user experience.

[0080] It is understandable that, in some possible examples, a limiting groove can be provided on the peripheral wall of the mouthpiece 12, and a protruding structure can be provided on the inner wall of the sleeve 212. The protruding structure is embedded in the limiting groove, thereby achieving a seal between the insertion part 21 and the mouthpiece 12 and preventing sound leakage.

[0081] Optional, refer to Figure 6 and Figure 7 As shown, Figure 6 This is a structural schematic diagram of the headphones provided in another embodiment of this application. Figure 7 yes Figure 6 A cross-sectional view along line DD. In this embodiment of the application, a plurality of reinforcing ribs 213 are provided between the peripheral wall of the sleeve 212 and the inner sidewall of the insertion part 21, and the plurality of reinforcing ribs 213 are respectively fixedly connected to the peripheral wall of the sleeve 212 and the inner sidewall of the insertion part 21.

[0082] Specifically, in this embodiment, the reinforcing rib 213 can be made of the same material as the sleeve 212 and the insertion part 21, which is silicone.

[0083] In some specific examples, the number of reinforcing ribs 213 may be three or more, and the three or more reinforcing ribs 213 are evenly spaced along the circumference of the sleeve 212.

[0084] In this way, by providing a reinforcing rib 213 between the sleeve 212 and the insertion part 21, the reinforcing rib 213 can support the peripheral wall of the insertion part 21. After the insertion part 21 is inserted into the ear canal, due to the support of the reinforcing rib 213, the peripheral wall of the insertion part 21 can make close contact with the inner wall of the ear canal, which can improve the noise reduction effect. In addition, when the ear is squeezed, the presence of the reinforcing rib 213 can increase the friction between the insertion part 21 and the inner wall of the ear canal, thereby improving the stability of the earphone and preventing the earphone from slipping out of the ear canal.

[0085] Optional, continue to refer to Figure 7 As shown, the reinforcing rib 213 is arranged radially inclined relative to the insertion part 21.

[0086] In other words, in this embodiment, there is a certain angle between the reinforcing rib 213 and the radial direction of the insertion part 21, the sleeve 212, or the mouthpiece 12. This design allows the inner wall of the ear canal to more easily compress the reinforcing rib 213 when the ear is squeezed and the shape of the ear canal changes, causing the reinforcing rib 213 to shift. That is, the peripheral wall of the insertion part 21 can more easily deform according to the deformation of the inner wall of the ear canal, without forming a strong resistance against the inner wall of the ear canal, thus improving the comfort of wearing the headphones.

[0087] Optionally, in this embodiment, the thickness of the reinforcing rib 213 is 0.4 to 0.8 mm.

[0088] In one specific example, the thickness of the reinforcing rib 213 is 0.6 mm.

[0089] It should be noted that the numerical values ​​and ranges involved in this application are approximate values. Due to the influence of the manufacturing process, there may be a certain range of errors, which can be considered negligible by those skilled in the art.

[0090] In this way, on the one hand, it saves on the material used for the reinforcing rib 213, and on the other hand, the strength of the reinforcing rib 213 is within a suitable range, which can improve the comfort of wearing the headphones.

[0091] In some possible examples, the length of the reinforcing rib 213 along the axial direction of the insertion portion 21 is greater than the length of the sleeve 212. The end of the reinforcing rib 213 facing away from the mouthpiece 12 has a guide surface (not shown in the figure). The guide surface is inclined relative to the axial direction of the mouthpiece 12 so that the multiple reinforcing ribs 213 are constricted along the insertion direction of the mouthpiece 12. Specifically, the guide surface can be an inclined surface or a curved arc surface.

[0092] In this way, by setting a guide surface on the reinforcing rib 213, the mouthpiece 12 can be easily guided, making it convenient for the mouthpiece 12 to be inserted into the sleeve 212.

[0093] Those skilled in the art will understand that the cross-section of the inner wall of the human ear canal is typically elliptical. To make the design of the earphone cover 20 more ergonomic and improve the comfort of wearing the earphones, reference is made to... Figure 7 As shown in the embodiment of this application, the cross-section of the insertion part 21 along the axis perpendicular to the mouthpiece 12 is elliptical.

[0094] This improves the comfort of wearing headphones and enhances the user experience.

[0095] Optional, refer to Figure 6 As shown in the embodiment of this application, the insertion part 21 also has a dustproof film 214, which is located on the outside of the mouthpiece 12 and has a plurality of sound holes.

[0096] Specifically, the dustproof film 214 blocks the mouthpiece 12 against the inner wall of the insertion part 21, and multiple sound holes connected to the mouthpiece 12 are provided on the dustproof film 214. In this way, dirt from inside the ear can be prevented from entering the mouthpiece 12 and affecting the sound of the headphones, thereby improving the sound quality of the headphones.

[0097] In another optional example of the embodiments of this application, refer to Figure 8 As shown, Figure 8 This is another structural schematic diagram of the earphone provided in the embodiment of this application. The inner wall of the insertion part 21 is in close contact with the peripheral wall of the mouthpiece 12. The insertion part 21 has an umbrella part 215, which extends in a direction away from the insertion of the insertion part 21. The umbrella part 215 and the peripheral wall of the insertion part 21 have a third gap 216.

[0098] Specifically, in this embodiment, the umbrella portion 215 is connected to the end of the insertion portion 21 and extends from the end of the insertion portion 21 to a side opposite to the insertion direction. This allows the umbrella portion 215 to be inserted into the ear canal in a forward direction and to contact the inner wall of the ear canal, thereby improving the noise reduction effect. A third rear gap 216 is formed between the umbrella portion 215 and the peripheral wall of the insertion portion 21.

[0099] In some other optional examples, refer to Figure 3 and Figure 9 As shown, Figure 9 This is a structural schematic diagram of the earphone provided in another embodiment of this application. The main body 10 also includes a cover 111 and a charging protrusion 112, which are connected to the host 11. At least one of the cover 111 and the charging protrusion 112 is exposed outside the earphone cover 20.

[0100] Specifically, in this embodiment, the cover 111 can be a decorative cover or a cover 111 equipped with a power switch or a function switch; wherein, the power switch or function switch can be a touch button or a physical button.

[0101] Reference Figure 2 and Figure 8 As shown, the cover 111 may also be provided with a microphone hole. When the user makes a call through the headset, the sound signal is transmitted to the host 11 through the microphone hole and converted into an electrical signal.

[0102] The charging protrusion 112 can be located on the side opposite to the cover 111, for example, the cover 111 and the charging protrusion 112 are located on both sides or at both ends of the main body axis.

[0103] This allows for convenient charging and control of the headphones, making them easy for users to operate.

[0104] Optional, refer to Figure 2As shown in the embodiment of this application, the earphone cover 20 has a first opening 201, which is located at the cover 111, and the diameter of the first opening 201 is smaller than the diameter of the cover 111.

[0105] In this way, after the earphone cover 20 is placed on the main body 10, the first opening 201 will form an inward shrinkage effect like a rubber band. The first opening 201 can be tightly attached to the peripheral wall of the cover 111, which can improve the stability of the connection between the earphone cover 20 and the main body 10. In addition, it can also improve the airtightness after the earphone cover 20 is connected to the main body 10, thereby improving the airbag effect of the first gap 223 and the second gap 211.

[0106] In some possible examples, the earphone cover 20 may also have a second opening 202 located at the charging protrusion 112, the diameter of which is smaller than the diameter of the charging protrusion 112.

[0107] In this way, after the earphone cover 20 is placed on the main body 10, the second opening 202 will form an inward shrinkage effect like a rubber band. The second opening 202 can be tightly attached to the peripheral wall of the charging protrusion 112, which can improve the stability of the connection between the earphone cover 20 and the main body 10. In addition, it can also improve the airtightness after the earphone cover 20 is connected to the main body 10, thereby improving the airbag effect of the first gap 223 and the second gap 211.

[0108] It should be noted that, to improve user comfort, the overall size of the earphones needs to be small, resulting in a very thin earphone shell design. This leads to a thinner shell at the charging protrusion 112, making it impossible to create a recessed structure within the thin shell, which hinders the installation and connection of the earphone sleeve 20. Therefore, referring to... Figure 10 and Figure 11 As shown, Figure 10 This is a schematic diagram of the structure of the main body of the earphone provided in the embodiment of this application. Figure 11 This is an exploded structural diagram of the main body of the earphone provided in the embodiment of this application. A charging cover 113 is provided at the charging protrusion 112, and the charging cover 113 is disposed on the charging protrusion 112.

[0109] The diameter of the charging cover 113 is larger than the diameter of the charging protrusion 112, so as to form a first groove 1131 between the charging cover 113 and the host 11. In this embodiment, the edge of the second opening 202 is embedded in the first groove 1131.

[0110] For specific settings, please refer to... Figure 11As shown, charging contacts can be positioned on the charging protrusion 112 and electrically connected to electrical components (such as a battery) inside the earphone. Then, the charging cover 113 is placed on the charging protrusion 112 using methods such as snaps, adhesives, bolts, or screws. In this way, since the diameter of the charging cover 113 is larger than the diameter of the charging protrusion 112, a first groove 1131 can be formed between the charging cover 113 and the main unit 11 at the outer edge of the charging cover 113.

[0111] This allows for easy fixing and positioning of the edge of the second opening 202 of the earphone cover 20, ensuring the integrity and aesthetics of the earphone cover 20 after installation and improving the user experience.

[0112] In specific settings, a sealing gasket (such as a silicone gasket, rubber ring, or sealant) can be placed between the charging cover 113 and the charging protrusion 112, and then the charging cover 113 and the charging protrusion 112 can be connected.

[0113] This ensures a sealed connection between the charging cover 113 and the charging protrusion 112, improving the earphone's water resistance and extending its lifespan.

[0114] In practical applications, refer to Figure 4 and Figure 6 As stated above, when the earphone is inserted into the ear canal, there is usually a certain angle between the ear canal and the concha. This angle exerts significant pressure on the insertion part 21 of the earphone cover 20 near the second opening 202, which often causes significant deformation of the insertion part 21 near the second opening 202. This deformation may cause the edge of the second opening 202 to detach from the first groove 1131, affecting the user experience. To address this situation, in an optional example, refer to... Figure 12 As shown, Figure 12 This is a schematic diagram of the structure of the earphone cover provided in the embodiment of this application. In this embodiment of the application, a limiting member 114 is provided on the inner side of the earphone cover 20. The limiting member 114 is located on the side of the edge of the second opening 202 near the insertion part 21. The limiting member 114 is embedded in the first groove 1131 and is used to prevent the edge of the second opening 202 from disengaging from the first groove 1131.

[0115] Specifically, the limiting member 114 can be a widened silicone strip. In specific designs, the limiting member 114 can be integrally molded with the earphone cover 20. In some possible examples, the limiting member 114 can also be obtained through secondary injection molding. In specific designs, the silicone strip can be configured as an arc-shaped structure matching the second opening 202. Thus, after the earphone cover 20 is installed on the body 10, the widened silicone strip can be embedded into the first groove 1131, increasing the contact area with the first groove 1131 and improving the frictional force, thereby limiting the displacement of the second opening 202. When the insertion part 21 is subjected to pressure, it can prevent the edge of the second opening 202 from dislodging from the first groove 1131.

[0116] In some cases, the limiting member 114 may also be a number of protrusions formed inside the second opening 202. Similarly, a number of protrusions may also be formed on the outer surface of the main unit 11, thereby increasing the friction between the inner side of the opening edge of the second opening 202 and the outer surface of the main unit 11, and limiting the opening edge of the second opening 202.

[0117] Optional, refer to Figure 2 and Figure 10 As shown, in another possible example of the embodiment of this application, the earphone cover 20 has a first opening 201, which is located at the cover 111; the cover 111 has a second groove 1111 on its peripheral wall, the first opening 201 has a protrusion 2011, the protrusion 2011 is arranged around the first opening 201, and its thickness is thicker than other parts of the support portion, and the protrusion 2011 is embedded in the second groove 1111.

[0118] The second groove 1111 can be integrally formed with the cover 111. In some possible examples, the second groove 1111 can also be formed by secondary processing such as grooving or drilling.

[0119] In a specific configuration, the protrusion 2011 and the second groove 1111 can be fitted together by an interference fit.

[0120] In one alternative example, the earphone cover 20 has a second opening 202 located at the charging protrusion 112; the peripheral wall of the charging protrusion 112 has a first groove 1131, and the edge of the second opening 202 has a protrusion that is embedded in the first groove 1131.

[0121] This improves the stability of the earphone covers 20 after they are placed on the main body 10, thus enhancing the user experience.

[0122] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
