Description

Technical Field

[0001] This application relates to the field of electronics, specifically to a connector and an electronic device. Background Technology

[0002] Open-ear stereo (OWS) headphones offer significantly improved comfort compared to true wireless stereo (TWS) headphones because they don't penetrate deep into the ear canal, making them popular among users who find in-ear headphones uncomfortable. Currently, OWS headphones are mainly available in two styles: clip-on and ear-hook. Clip-on headphones use elastic elements in the connector to hold the acoustic components and battery in place on the ear; ear-hook headphones use ear hooks to hang the headphones on the ear.

[0003] In related technologies, the connectors use an overmolding process, meaning the overmolding layer completely covers the elastic element, making it impossible to add any additional appearance design through the elastic element or other components, resulting in a relatively simple appearance design. Utility Model Content

[0004] This application provides a connector in which at least a portion of the elastic element is exposed. The elastic element can be part of the appearance of the connector, thereby giving the connector a better appearance.

[0032] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present application.

[0033] The terms "first," "second," etc., in the specification, claims, and accompanying drawings of this application are used to distinguish different objects, not to describe a specific order. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion. For example, a process, method, system, product, or apparatus that includes a series of steps or units is not limited to the listed steps or units, but may optionally include steps or units not listed, or may optionally include other steps or units inherent to these processes, methods, products, or apparatuses.

[0034] The technical solutions in the embodiments of this application will now be described with reference to the accompanying drawings.

[0035] It should be noted that, for ease of explanation, the same reference numerals denote the same components in the embodiments of this application, and for the sake of brevity, detailed descriptions of the same components are omitted in different embodiments.

[0036] Open-ear stereo (OWS) headphones offer significantly improved comfort compared to true wireless stereo (TWS) headphones because they don't penetrate deep into the ear canal. Therefore, they are popular among users who find in-ear headphones uncomfortable. Currently, OWS headphones are mainly available in two types: clip-on and ear-hook. Clip-on headphones use a connector to clamp the acoustic components and battery onto the ear; ear-hook headphones use ear hooks to hang the headphones on the ear.

[0037] In related technologies, the connectors use an overmolding process, meaning the overmolding layer completely covers the elastic element, making it impossible to add any additional appearance design through the elastic element or other components, resulting in a relatively simple appearance design.

[0038] Therefore, embodiments of this application provide a connector, an electronic device, and an audio device.

[0039] Figure 1 This is a schematic diagram of the structure of a connector 100 according to an embodiment of this application. Figure 2 This is an exploded structural diagram of a connector 100 according to an embodiment of this application.

[0040] Please see Figure 1 and Figure 2 This application provides a connector 100 (also known as a connecting bridge), the connector 100 includes a covering layer 10 and an elastic member 20, the elastic member 20 being at least partially exposed outside the covering layer 10.

[0041] The connector 100 of this application embodiment can be applied to, but is not limited to, electronic devices such as headphones. In the embodiments of this application, the electronic device is illustrated using headphones as an example, and should not be construed as limiting the electronic device of this application embodiment, nor should it be construed as limiting the connector 100 of this application embodiment.

[0042] The connector 100 of this application is an elastic connection structure with rebound properties, which can be used to connect a first component (also known as an acoustic part, sound-emitting ball, etc., i.e., the component in the headphones used to emit sound) and a second component (also known as a battery part, battery bead, etc., i.e., the component in the headphones used to hold batteries and provide power) of an electronic device such as headphones. In other embodiments, the connector 100 can also be applied to other electronic devices where two components need to be elastically connected. The internal circuit of the connector 100 can be designed to realize an end-to-end electrical connection. In the embodiments of this application, the connector 100 is described and illustrated using headphones as an example, and should not be construed as a limitation on the connector 100 of the embodiments of this application. It should be noted that when the connector 100 is applied to headphones, the connector 100 can be a mechanical connection component with an arch-like shape, used to connect the sound-emitting ball and battery bead of the headphones.

[0043] Understandably, the covering layer 10 surrounds the outer periphery of the elastic member 20. It is also understood that the elastic member 20 is embedded in the covering layer 10, and the elastic member 20 is at least partially visible. In some embodiments, the elastic member 20 is partially visible because the covering layer 10 covers a portion of the surface of the elastic member 20, with the remaining surface exposed. In other embodiments, the elastic member 20 is partially visible because the covering layer 10 covers the entire outer surface of the elastic member 20. The covering layer 10 is partially opaque, partially transparent, or semi-transparent, with the transparent or semi-transparent portions making the elastic member 20 visible, allowing the appearance of the circuitry portion of the elastic member 20, such as color and pattern, to be seen.

[0044] It should be noted that the elastic element 20 is used to provide a restoring force to the connector 100. When the connector 100 is bent or deformed, the elastic restoring force of the elastic element 20 causes the elastic element 20 to return to its natural state.

[0045] Optionally, the number of elastic elements 20 in the connector 100 can be one or more (e.g., two, three, four, etc.). When there are multiple elastic elements 20, they are spaced apart. In some embodiments, multiple elastic elements 20 can be arranged side by side. Multiple elastic elements 20 can be stacked sequentially and spaced apart. The term "multiple" means two or more.

[0046] The connector 100 in this embodiment includes a covering layer 10 and an elastic element 20, wherein the elastic element 20 is at least partially exposed outside the covering layer 10. The exposed portion of the elastic element 20 can be part of the appearance of the connector 100, thereby giving the connector 100 a better appearance. In addition, the exposed portion of the elastic element 20 can also be designed through laser engraving, printing, or other processes, or additional decorative parts can be assembled, thereby achieving diversified design of the connector 100's appearance, breaking the monotony of the appearance design, and thus giving the connector 100 a better appearance.

[0047] Optionally, the connector 100 has an arc-shaped structure, and the radius of curvature of the connector 100 can be equal or gradually varied along its extension direction. Optionally, the elastic member 20 has an arc-shaped structure, and the radius of curvature of the elastic member 20 can be equal or gradually varied along its extension direction.

[0048] Optionally, the connector 100 may be generally arc-shaped, C-shaped, U-shaped, or teardrop-shaped.

[0049] Optionally, the elastic element 20 can be approximately arc-shaped, C-shaped, U-shaped, or teardrop-shaped. It should be noted that the bending shape of the connector 100 follows the bending shape of the elastic element 20 and remains consistent with it.

[0050] Figure 3 This is a schematic diagram of the elastic member 20 in different states according to an embodiment of this application; in (a), the elastic member 20 is in an expanded state; in (b), the elastic member 20 is in a natural state; in (c), the elastic member 20 is in a compressed state.

[0051] Please see also Figure 1 and Figure 3 Optionally, the elastic member 20 has a natural state and an expanded state. The elastic member 20 includes a first end 21 and a second end 22. When the elastic member 20 is in the natural state, the first end 21 and the second end 22 have a first distance. When the elastic member 20 is in the expanded state, the first end 21 and the second end 22 have a second distance. The first distance is less than the second distance.

[0052] It should be noted that the natural state refers to the state in which the elastic element 20 is not subjected to external force, while the expanded state refers to the state in which the first end 21 and the second end 22 of the elastic element 20 generate an elastic restoring force that reduces the distance between the first end 21 and the second end 22; in other words, the first end 21 and the second end 22 are subjected to tensile stresses in opposite directions. It can be understood that when the elastic element 20 is in the expanded state, it tends to return to its natural state. It can also be understood that when the elastic element 20 is in the expanded state, it generates an elastic restoring force, and this force gradually increases with the increase of the second distance.

[0053] Optionally, the first end 21 and the second end 22 are the two ends of the elastic member 20 that are opposite to each other.

[0054] It should be noted that when the first end 21 and the second end 22 of the elastic element 20 are subjected to tensile stress and expand outward, the elastic element 20 generates an elastic restoring force when it is in an expanded state. Under the action of the elastic restoring force, the distance between the first end 21 and the second end 22 decreases, causing the elastic element 20 to return to its natural state. When the connector 100 is applied to electronic devices such as headphones, it causes the first and second components of the headphones or other electronic devices to generate a force (also known as a clamping force) or tendency to decrease the distance, thereby clamping them to the target object (such as the ear, head, etc.) and preventing them from falling off. Understandably, the connector 100 provides a flexible connection for the headphones, achieving the clamping and wearing of the headphones by outputting a restoring force, ensuring that the headphones are worn securely and reliably, and are not prone to deformation over long-term use.

[0055] It should be noted that the elastic element 20 also has a compressed state. When the elastic element 20 is in a compressed state, the first end 21 and the second end 22 have a third distance, which is less than the first distance. The compressed state refers to the state in which the first end 21 and the second end 22 of the elastic element 20 are subjected to compressive stress in opposite directions.

[0056] Please see again Figure 1 Optionally, the covering layer 10 includes a third end 11 and a fourth end 12, the first end 21 of the elastic member 20 is disposed near the third end 11 of the covering layer 10, and the second end 22 of the elastic member 20 is disposed near the fourth end 12 of the covering layer 10.

[0057] Optionally, the covering layer 10 is a flexible covering layer 10, in other words, the covering layer 10 is flexible.

[0058] Optionally, the material of the covering layer 10 can be, but is not limited to, at least one of soft rubbers such as plastic, silicone, and thermoplastic elastomer (TPE).

[0059] Optionally, the thermoplastic elastomer may be, but is not limited to, at least one of thermoplastic polyurethane (TPU), thermoplastic polystyrene, thermoplastic polyester, etc.

[0060] Optionally, the elastic element 20 is connected to the covering layer 10. Optionally, the elastic element 20 and the covering layer 10 can be integrated through processes such as hot pressing or injection molding. That is, the covering layer 10 wraps a portion of the surface of the elastic element 20 through processes such as hot pressing or injection molding. The covering layer 10 and the elastic element 20 are integrally formed by hot pressing or injection molding, thereby saving the preparation and assembly costs of the connector 100 (i.e., saving the cost of disassembling the connector 100).

[0061] In some embodiments, the elastic element 20 is a shape memory element, which is at least one of a sheet structure, a columnar structure (i.e., a solid structure), and a tubular structure (i.e., a hollow structure). Compared to columnar and tubular structures, the sheet structure allows for a larger contact area between the shape memory element and the covering layer 10, thereby resulting in better bonding between the elastic memory element and the covering layer 10; furthermore, it can have a larger exposed area, allowing for better design of the connector.

[0062] Figure 4 The elastic element 20 of one embodiment of this application is along Figure 1 A schematic diagram of the cross-sectional structure along the AA direction.

[0063] Please see Figure 4 In some embodiments, the connector 100 has a flat structure, and the elastic element 20 is a shape memory metal sheet, the shape memory metal sheet including a first surface 23, a second surface 24, a third surface 25 and a fourth surface 26, at least a portion of at least one of the first surface 23, the second surface 24, the third surface 25 and the fourth surface 26 is exposed outside the covering layer 10.

[0064] It should be noted that the first side 23 and the fourth side 26 are set opposite to each other, and the second side 24 and the third side 25 are set opposite to each other.

[0065] Understandably, the first side 23, the second side 24, the third side 25, and the fourth side 26 are connected end to end in sequence.

[0066] Optionally, the first surface 23 extends from the first end 21 to the second end 22; the second surface 24 extends from the first end 21 to the second end 22; the third surface 25 extends from the first end 21 to the second end 22; and the fourth surface 26 extends from the first end 21 to the second end 22.

[0067] Optionally, the length of the elastic element 20 is greater than the width of the elastic element 20, and the width of the elastic element 20 is greater than the thickness of the elastic element 20; in other words, the elastic element 20 is a flat structure or a sheet structure.

[0068] Optionally, the covering layer 10 extends along the length of the elastic member 20; it can also be understood that the elastic member 20 extends from one end of the covering layer 10 to the other end.

[0069] Optionally, the memory metal sheet can be made of a resilient memory material.

[0070] Optionally, the shape memory metal sheet may include, but is not limited to, at least one of titanium-nickel alloy sheets, copper-based alloy sheets, and iron-based alloy sheets. In other words, the material of the shape memory metal sheet may be, but is not limited to, at least one of titanium-nickel alloy, copper-based alloy, and iron-based alloy.

[0071] Understandably, the cross-section of the covering layer 10 is a flat structure. Optionally, the cross-section of the covering layer 10 can be, but is not limited to, at least one of a flat runway structure, an approximately elliptical structure, etc.

[0072] In related technologies, the elastic element 20 inside the connector 100 is a single metal wire (such as titanium wire) with a long span, which provides limited resilience. The connector 100 is prone to deformation due to repeated bending and stretching over a long period of time, making it difficult to return to its original state. On the other hand, the overall cross-sectional area of ​​the single metal wire is small, resulting in a small bonding area with the coating layer 10. After long-term use, the coating layer 10 may age and face risks such as delamination and outer sheath cracking.

[0073] In this embodiment, compared to the solution using a wire elastic element 20, the elastic element 20 of this application is a shape memory metal sheet, which can provide more stable rebound force, is less prone to deformation, and the metallic luster of the shape memory metal sheet can give the connector 100 a better appearance. Furthermore, the sheet-like structure of the elastic element 20 and the covering layer 10 has a larger bonding area, resulting in a stronger bond between the elastic element 20 and the covering layer 10. This makes it less likely for the elastic element 20 and the covering layer 10 to separate, and less likely for the elastic element 20 to puncture the covering layer 10. Consequently, the connector 100 can withstand more repeated bending and has a longer service life. Moreover, the sheet-like elastic element 20 and the flat structure of the covering layer 10 allow for more diverse designs of the visible portion of the elastic element 20, thus enabling a more varied appearance design for the connector 100.

[0074] Figure 5 The elastic element 20 in another embodiment of this application is along Figure 1 A schematic diagram of the cross-sectional structure along the AA direction. Figure 6 This is a structural schematic diagram of the connector 100 according to another embodiment of this application.

Figure 9This is a cross-sectional structural schematic diagram of the connector 100 along the visible portion of the elastic member 20 according to an embodiment of this application.

[0075] Please see also Figures 4 to 9 In some embodiments, the connector 100 has a plurality of cross sections, at least a portion of which satisfy at least one of the following conditions:

[0076] like Figure 4 As shown, the covering layer 10 covers a portion of the second surface 24, a portion of the third surface 25, and a portion of the fourth surface 26, while the remaining portions of the first surface 23, the second surface 24, and the fourth surface 26 are exposed outside the covering layer 10.

[0077] like Figure 5 As shown, the covering layer 10 covers the second surface 24, the third surface 25 and the fourth surface 26, while the first surface 23 is exposed outside the covering layer 10;

[0078] like Figure 9 As shown, the covering layer 10 covers a portion of the first surface 23, the second surface 24, the third surface 25, and the fourth surface 26, while the remaining portion of the first surface 23 is exposed outside the covering layer 10.

[0079] Optionally, the cross-section is a cross-section perpendicular to the extending direction of the connector 100. When the connector 100 is arc-shaped, the cross-section is perpendicular to the tangent of the connector 100 at that location; in other words, the cross-section extends radially along the arc-shaped structure.

[0080] In some embodiments, the plurality of cross sections of the connector 100 satisfy the following conditions: the covering layer 10 covers a portion of the second surface 24, a portion of the third surface 25 and a portion of the fourth surface 26, and the remaining portions of the first surface 23, the second surface 24 and the fourth surface 26 are exposed outside the covering layer 10.

[0081] In some embodiments, the plurality of cross sections of the connector 100 all satisfy the following conditions: the covering layer 10 covers the second surface 24, the third surface 25 and the fourth surface 26, and the first surface 23 is exposed outside the covering layer 10.

[0082] In some embodiments, the plurality of cross sections of the connector 100 all satisfy the following conditions: the covering layer 10 covers a portion of the first surface 23, the second surface 24, the third surface 25 and the fourth surface 26, and the remaining portion of the first surface 23 is exposed outside the covering layer 10.

[0083] In some embodiments, portions of the plurality of cross-sections of the connector 100 satisfy the following conditions: the covering layer 10 covers portions of the second surface 24, the third surface 25, and the fourth surface 26, while the remaining portions of the first surface 23, the second surface 24, and the fourth surface 26 are exposed outside the covering layer 10; the remaining portions of the plurality of cross-sections of the connector 100 satisfy the following conditions: the covering layer 10 covers the second surface 24, the third surface 25, and the fourth surface 26, while the first surface 23 is exposed outside the covering layer 10.

[0084] In some embodiments, portions of the plurality of cross-sections of the connector 100 satisfy the following conditions: the covering layer 10 covers portions of the second surface 24, the third surface 25, and the fourth surface 26, while the remaining portions of the first surface 23, the second surface 24, and the fourth surface 26 are exposed outside the covering layer 10; the remaining portions of the plurality of cross-sections of the connector 100 satisfy the following conditions: the covering layer 10 covers portions of the first surface 23, the second surface 24, the third surface 25, and the fourth surface 26, while the remaining portions of the first surface 23 are exposed outside the covering layer 10.

[0085] In some embodiments, portions of the plurality of cross-sections of the connector 100 satisfy the following conditions: the covering layer 10 covers the second surface 24, the third surface 25, and the fourth surface 26, and the first surface 23 is exposed outside the covering layer 10; the remaining portions of the plurality of cross-sections of the connector 100 satisfy the following conditions: the covering layer 10 covers a portion of the first surface 23, the second surface 24, the third surface 25, and the fourth surface 26, and the remaining portion of the first surface 23 is exposed outside the covering layer 10.

[0086] In some embodiments, a portion of the plurality of cross-sections of the connector 100 satisfies the following: the covering layer 10 covers a portion of the second surface 24, a portion of the third surface 25 and a portion of the fourth surface 26, and the remaining portions of the first surface 23, the second surface 24 and the fourth surface 26 are exposed outside the covering layer 10; another portion of the plurality of cross-sections of the connector 100 satisfies the following: the covering layer 10 covers a portion of the second surface 24, the third surface 25 and the fourth surface 26, and the first surface 23 is exposed outside the covering layer 10; the remaining portions of the plurality of cross-sections of the connector 100 satisfies the following: the covering layer 10 covers a portion of the first surface 23, the second surface 24, the third surface 25 and the fourth surface 26, and the remaining portions of the first surface 23 are exposed outside the covering layer 10.

[0087] In this embodiment, by designing the connection between the covering layer 10 and the elastic member 20 on the cross-section of the connector 100, the appearance of the connector 100 can be designed in a more diverse way, so that the connector 100 has a more diverse appearance and can better meet the needs of different users.

[0088] Please see again Figure 1 , Figure 2 and Figure 4 In some embodiments, the covering layer 10 covers a portion of the second surface 24, a portion of the third surface 25 and a portion of the fourth surface 26, while the remaining portions of the first surface 23, the second surface 24 and the fourth surface 26 are exposed outside the covering layer 10.

[0089] Understandably, the first surface 23 of the elastic member 20 is entirely exposed to the covering layer 10; the second surface 24 and the fourth surface 26 are both partially covered by the covering layer 10 and partially exposed to the covering layer 10; the third surface 25 is entirely covered by the covering layer 10. It is also understood that in this embodiment, the covering layer 10 includes the back and part of the side of the elastic member 20 (i.e., half-covering the side), meaning the entire front of the elastic member 20 is exposed to the covering layer 10.

[0090] Optionally, the covering layer 10 has a groove 14, the elastic member 20 is located in the groove 14, a portion of the elastic member 20 is located in the groove 14, and the remaining portion of the elastic member 20 protrudes from the groove 14.

[0091] Optionally, the covering layer 10 has a preset surface 13 and a groove 14, the groove 14 penetrating a portion of the preset surface 13, the elastic member 20 being located within the groove 14, and the elastic member 20 protruding from the preset surface 13 away from the surface of the covering layer 10 (i.e., the first surface 23). In other words, the elastic member 20 is partially embedded in the groove 14 and partially protrudes from the groove 14.

[0092] Understandably, the first surface 23 is the surface that faces away from the covering layer 10.

[0093] In this embodiment, the covering layer 10 partially covers the second surface 24, the third surface 25, and part of the fourth surface 26. Therefore, the exposed portion of the elastic element 20 can be considered part of the appearance of the connector 100. Furthermore, the exposed portion of the elastic element 20 can be designed with diverse aesthetic features, resulting in a more varied and aesthetically pleasing appearance for the connector 100. When the elastic element 20 is a shape-memory metal sheet, the connector 100 can exhibit a metallic luster and texture, giving it a better appearance and feel. Please refer to [link / reference]. Figure 5In some embodiments, the covering layer 10 covers the second surface 24, the third surface 25 and the fourth surface 26, while the first surface 23 is exposed outside the covering layer 10.

[0094] Understandably, the first surface 23 of the elastic element 20 is entirely exposed to the covering layer 10, while the second surface 24, the third surface 25, and the fourth surface 26 are entirely covered by the covering layer 10. It is also understood that, in this embodiment, the covering layer 10 includes the back and all sides of the elastic element 20 (i.e., fully covering the sides). In this embodiment, the entire front surface of the elastic element 20 is exposed to the covering layer 10.

[0095] Optionally, the covering layer 10 has a preset surface 13 and a groove 14, the groove 14 penetrates a portion of the preset surface 13, the elastic member 20 is located in the groove 14, and the surface of the elastic member 20 facing away from the covering layer 10 (i.e., the first surface 23) smoothly transitions or is flush with the preset surface 13.

[0096] In this embodiment, the covering layer 10 covers the second surface 24, the third surface 25, and the fourth surface 26, while the first surface 23 is exposed outside the covering layer 10. This allows for a smooth transition or flush alignment between the first surface 23 of the elastic element 20 and the preset surface 13 of the covering layer 10, resulting in a smoother overall appearance and better feel for the connector 100. Furthermore, the exposed portion of the elastic element 20 can be designed with diverse aesthetic features, further enhancing the appearance and overall aesthetic appeal of the connector 100. When the elastic element 20 is a shape memory metal sheet, the connector 100 can exhibit a metallic luster and texture, resulting in a superior appearance and feel.

[0097] The above Figure 4 In this design, the elastic element 20 has a larger exposed surface, providing greater design flexibility and allowing for more diverse design options, resulting in a better overall appearance for the connector 100. Figure 5 In this design, the bonding area between the covering layer 10 and the elastic element 20 is larger, resulting in a stronger bond between them. This makes it less likely for the elastic element 20 to separate from the covering layer 10, and less likely for the elastic element 20 to puncture the covering layer 10. Consequently, the connector 100 can withstand more repeated bending and has a longer service life. Please refer to [link to relevant documentation]. Figures 6 to 9 In some embodiments, the covering layer 10 covers a portion of the first surface 23, the second surface 24, the third surface 25, and the fourth surface 26, with the remaining portion of the first surface 23 exposed outside the covering layer 10.

[0098] Understandably, the first surface 23 of the elastic member 20 is partially exposed and covered by the covering layer 10, while the second surface 24, the third surface 25, and the fourth surface 26 are entirely covered by the covering layer 10. It is also understood that the connector 100 not only covers the back and sides of the elastic member 20 but also extends to cover the front surface of the elastic member 20. In this embodiment, the front surface of the elastic member 20 is partially exposed by the covering layer 10.

[0099] In this embodiment, only a portion of the first surface 23 of the elastic element 20 is exposed outside the covering layer 10. The covering layer 10 and the elastic element 20 have a larger bonding area, resulting in a stronger bonding force between them. This makes it less likely for the elastic element 20 to separate from the covering layer 10, and less likely for the elastic element 20 to puncture the covering layer 10. Consequently, the connector 100 can withstand more repeated bending and has a longer service life. As the area of ​​the covering layer 10 that encloses the elastic element 20 increases, the bonding force between the covering layer 10 and the elastic element 20 increases accordingly, reducing the risk of separation between the covering layer 10 and the elastic element 20 (i.e., reducing the risk of delamination).

[0100] Figure 10 This application Figure 6 An exploded view of the connector 100 in the embodiment.

[0101] Please see Figure 10 The covering layer 10 has a preset surface 13 and a groove 14. The groove 14 penetrates a portion of the preset surface 13. The elastic member 20 is located in the groove 14. The first surface 23 is closer to the preset surface 13 than the second surface 24. The first surface 23 is lower than the preset surface 13.

[0102] Understandably, the first surface 23 is lower than the opening of the sink 14.

[0103] Understandably, the elastic element 20 is partially exposed on the surface of the covering layer 10 and recessed in the groove 14.

[0104] Understandably, the sink 14 is located on the preset surface 13, that is, the preset surface 13 is partially recessed to form the sink 14.

[0105] It should be noted that, in this embodiment, the covering layer 10 covers the second surface 24, the third surface 25 and the fourth surface 26, and the first surface 23 is partially covered by the covering layer 10 and partially exposed outside the covering layer 10.

[0106] In this embodiment, only a portion of the first surface 23 of the elastic element 20 is exposed outside the covering layer 10. The covering layer 10 and the elastic element 20 have a larger bonding area, resulting in a stronger bond between them. This makes it less likely for the elastic element 20 to separate from the covering layer 10, and less likely for the elastic element 20 to puncture the covering layer 10. Consequently, the connector 100 can withstand more repeated bending, resulting in a longer service life. Furthermore, the exposed portion of the first surface 23 of the elastic element 20 allows for diverse design options, leading to a more varied and aesthetically pleasing appearance for the connector 100. When the elastic element 20 is a shape-memory metal sheet, the connector 100 can exhibit a metallic luster and texture, further enhancing its appearance and overall quality.

[0107] Figure 11 This application Figure 7 or Figure 8 A structural schematic diagram of the connector 100 in the embodiment from another perspective.

[0108] Please see Figure 7 , Figure 8 ,and Figure 11 The covering layer 10 has a preset surface 13, a receiving groove 15 and at least one opening 16. The receiving groove 15 is used to pass through the elastic member 20. The at least one opening 16 connects to the receiving groove 15 and passes through the preset surface 13. When the number of openings 16 is at least two, the at least two openings 16 are spaced apart.

[0109] Understandably, the at least one opening 16 exposes a portion of the first surface 23 to the covering layer 10. Understandably, in this embodiment, the elastic element 20 may be partially exposed at a single point or at multiple points.

[0110] Understandably, the elastic element 20 has multiple exposed portions, which are spaced apart. In other words, the first surface 23 has multiple exposed portions, which are spaced apart.

[0111] Optionally, the receiving groove 15 extends from the third end 11 to the fourth end 12.

[0112] In this embodiment, at least one portion of the elastic element 20 is exposed to the covering layer 10 through at least one opening 16, thereby forming a structure on the predetermined surface 13 side of the covering layer 10 where the appearance of the elastic element 20 and the appearance of the covering layer 10 alternate, resulting in a better appearance for the connector 100. Furthermore, the elastic element 20 is entirely inserted through the receiving groove 15, with the portion corresponding to the opening 16 exposed, maximizing the bonding area between the elastic element 20 and the covering layer 10. This makes it less likely for the elastic element 20 to separate from the covering layer 10 and less likely for the elastic element 20 to puncture the covering layer 10, allowing the connector 100 to withstand more repeated bending and thus having a longer service life.

[0113] Please see again Figures 6 to 8 ,and Figure 10 In some embodiments, the exposed portion of the elastic element 20 has a textured structure 17.

[0114] It should be noted that the texture structure 17 can be at least one of the following: logo, raised area, groove, pattern, color, etc.

[0115] In this embodiment, the portion of the elastic element 20 exposed outside the covering layer 10 is provided with a textured structure 17, which allows the connector 100 to have a better appearance.

[0116] In some embodiments, the texture structure 17 includes at least one of laser engraving texture, etching texture, printing texture, electroplating texture, and physical vapor deposition texture (PVD).

[0117] It should be noted that the texture structure 17 can be formed by laser engraving, etching, printing, physical vapor deposition, electroplating, etc.

[0118] In this embodiment, by setting different types of texture structures 17 on the elastic element 20, the connector 100 can have different appearance effects. In addition, a logo can also be set on the texture structure 17 to make the product more eye-catching.

[0119] Figure 12 This is a structural schematic diagram of the connector 100 according to another embodiment of this application. Figure 13 This is an exploded structural diagram of the connector 100 according to another embodiment of this application. Figure 14 The connector 100 is another embodiment of this application. Figure 1 A schematic diagram of the cross-sectional structure along the AA direction.

[0120] Please see Figures 12 to 14 In some embodiments, the connector 100 further includes a decorative element 30 that covers at least a portion of the elastic element 20 exposed in the covering layer 10.

[0121] Optionally, the decorative element 30 is at least one of a transparent decorative element 30 or a semi-transparent decorative element 30.

[0122] It should be noted that the decorative element 30 may cover part or all of the exposed surface of the elastic element 20. In other embodiments, the decorative element 30 may cover not only the elastic element 20 but also part of the covering layer 10.

[0123] Optionally, the decorative element 30 is a decorative piece. The decorative element 30 can be formed on the exposed surface of the elastic element 20 by injection molding (i.e., secondary injection molding). In other embodiments, the decorative element 30 can also be attached to the exposed surface of the elastic element 20 by means of a patch.

[0124] Optionally, the decorative element 30 has a color. Optionally, the color of the decorative element 30 can be a bright, light color, which can better present the appearance of the elastic element 20. In addition, when the elastic element 20 has a textured structure 17, the texture effect of the elastic element 20 can be better presented. Optionally, the color of the decorative element 30 can be, but is not limited to, at least one of red, yellow, green, blue, orange, cyan, purple, pink, etc.

[0125] In this embodiment, by providing the decorative element 30, the connector 100 can have a better appearance. When the decorative element 30 is transparent or semi-transparent, the color and gloss of the elastic element 20 appear more transparent. When the elastic element 20 has a textured structure 17, the transparent or semi-transparent decorative element 30 can make the textured structure 17 appear more three-dimensional, thereby giving the connector 100 a better appearance. Furthermore, by providing the decorative element 30, the diversity of the connector 100's appearance design can be increased.

[0126] Figure 15 The connector 100 is another embodiment of this application. Figure 1 A schematic diagram of the cross-sectional structure along the AA direction.

[0127] Please see Figure 10 , Figures 13 to 15 In some embodiments, the covering layer 10 has a preset surface 13 and a through groove 18, the elastic member 20 is at least partially exposed on the preset surface 13, and the through groove 18 is located on the side of the elastic member 20 away from the preset surface 13; the connector 100 also includes a flexible circuit board 40 (abbreviated as FPC), the flexible circuit board 40 is disposed through the through groove 18 and is insulated from the elastic member 20.

[0128] Understandably, the through grooves 18 are spaced apart on the side of the elastic member 20 opposite to the preset surface 13.

[0129] Please see Figure 11 Optionally, the covering layer 10 further has a first end face 19a and a second end face 19b. The first end face 19a is connected to one end of the preset surface 13, and the second end face 22 is connected to the other end of the preset surface 13. The through groove 18 passes through the first end face 19a and the second end face 19b respectively.

[0130] Optionally, the first end face 19a is located at the third end face 11, and the second end face 19b is located at the fourth end face 12.

[0131] Understandably, the flexible circuit board 40 is located on the side of the elastic member 20 that is away from the preset surface 13.

[0132] Optionally, a through groove 18 is formed when the covering layer 10 and the elastic element 20 are integrally injection molded, so that the flexible circuit board 40 passes through the elastic element 20 from below and is assembled onto the covering layer 10.

[0133] It should be noted that the flexible circuit board 40 and the elastic element 20 are insulated from each other. Optionally, the flexible circuit board 40 and the elastic element 20 are separated by a covering layer 10 to achieve insulation.

[0134] It should be noted that when the connector 100 is used in electronic devices such as headphones, the flexible circuit board 40 is used to electrically connect the headphone's main board and the speaker.

[0135] Optionally, the flexible circuit board 40 includes one or more first signal lines (not shown). When the flexible circuit board 40 includes multiple first signal lines, the multiple first signal lines are stacked and insulated from each other. In some embodiments, the flexible circuit board 40 further includes an insulating substrate (not shown), which is sleeved on the outer periphery of the multiple first signal lines; in other words, the multiple first signal lines pass through the insulating substrate.

[0136] The term "multiple roots" refers to two or more roots. For example, 2 roots, 3 roots, 4 roots, 5 roots, 6 roots, 7 roots, 8 roots, 9 roots, etc.

[0137] Optionally, the flexible circuit board 40 and the elastic element 20 are stacked along the thickness direction of the flexible circuit board 40.

[0138] In related technologies, the wires in the connector 100 are multi-stranded wires (such as multi-strand copper wires). The wires pass through the inside of the sheathing layer 10. When the headphone has multiple functions, the number of strands in the multi-stranded wire is large, resulting in a large cross-sectional area. This occupies a significant amount of radial space inside the sheathing layer 10, thus limiting the cross-sectional design of the connector 100. Therefore, the cross-section of the connector 100 is mostly close to a circular or elliptical shape, with other shapes being less common. Furthermore, the appearance design of the connector 100 is achieved through surface treatments such as spraying on the sheathing layer 10. The design of the connector 100 is relatively simple, and its thickness is relatively large.

[0139] In this embodiment, a flexible circuit board 40 is used instead of the copper wire stranded wire of the related technology. This allows for a smaller cross-sectional thickness of the connector 100, enabling a flatter design. The flatter appearance results in a larger flat surface on the connector 100, allowing for better design and a more aesthetically pleasing appearance. Furthermore, using a flexible circuit board 40 reduces the need for connectors, supports high-density wiring, and simplifies the headphone's structural design. Moreover, the flexible circuit board 40 effectively reduces electromagnetic interference (EMI) from high-frequency signals (such as Bluetooth audio), lowering noise and improving sound quality. It also allows for more precise impedance control, suitable for high-speed data transmission. Finally, the flexible circuit board 40 offers better bending and vibration resistance.

[0140] Please see again Figure 15 In some embodiments, the flexible circuit board 40 includes an antenna 41.

[0141] It should be noted that the antenna 41 is located within the through slot 18, and the antenna 41 is used to transmit and receive electromagnetic wave signals.

[0142] Optionally, antenna 41 can be, but is not limited to, at least one of LDS laser-etched antenna 41 and FPC antenna 41.

[0143] In related technologies, the antenna 41 is usually located inside the earphone's battery holder or battery section, and the connector 100 only serves to flexibly connect the first and second components of the earphone and to conduct internal circuitry, resulting in a relatively simple overall functional design. This embodiment, by placing the antenna 41 on the flexible circuit board 40, does not increase the size of the connector 100, but significantly saves stacking space in the earphone's battery holder or battery section, making the entire earphone more compact, better optimizing the overall functional design, and giving the earphone a better appearance.

[0144] Figure 16 The connector 100 is another embodiment of this application. Figure 1 A schematic diagram of the cross-sectional structure along the AA direction.

[0145] Please see Figure 16 In other embodiments, the covering layer 10 has a preset surface 13 and a through groove 18, the elastic member 20 is at least partially exposed on the preset surface 13, and the through groove 18 is located on the side of the elastic member 20 away from the preset surface 13; the connector 100 also includes a cable 50, which passes through the through groove 18.

[0146] Optionally, the cable 50 includes one or more second signal lines (not shown). When the cable 50 includes multiple second signal lines, the multiple second signal lines are stacked and insulated from each other. In some embodiments, the cable 50 also includes a sleeve that is fitted around the outer periphery of the second signal lines; in other words, the second signal lines pass through the sleeve (not shown). When the cable 50 includes multiple second signal lines, the multiple second signal lines form a cable bundle.

[0147] It should be noted that when the connector 100 is used in electronic devices such as headphones, the cable 50 is electrically connected to the motherboard and the speaker respectively.

[0148] In this embodiment, compared to the solution of using a flexible circuit board 40 to realize the electrical connection between the motherboard and the speaker, the solution of using a cable 50 to realize the connection between the motherboard and the speaker has a lower cost; furthermore, the cable 50 has a higher current carrying capacity and can support higher current; furthermore, if a single second signal line in the cable 50 is damaged, it can be replaced without the need for the entire cable to be scrapped; furthermore, the routing of the cable 50 is easier to adjust, which allows for more flexible design of headphones, etc.

[0149] Please see Figure 17 and Figure 18 The elastic member 20 includes a body portion 20a, a first limiting portion 20b and a second limiting portion 20c. The first limiting portion 20b and the second limiting portion 20c are respectively protruding on opposite sides of the body portion 20a, and the first limiting portion 20b and the second limiting portion 20c are respectively embedded in the covering layer 10.

[0150] Optionally, the number of the first limiting part 20b can be one or more. When the number of the first limiting part 20b is multiple, the multiple first limiting parts 20b are spaced apart on the same side of the body part 20a.

[0151] Optionally, the number of the second limiting part 20c can be one or more. When the number of the second limiting part 20c is multiple, the multiple second limiting parts 20c are spaced apart on the same side of the body part 20a.

[0152] Optionally, the first limiting part 20b can be, but is not limited to, at least one of a protruding column, a protruding rib, a protruding strip, etc.

[0153] Optionally, the second limiting part 20c can be, but is not limited to, at least one of a protruding column, a protruding rib, a protruding strip, etc.

[0154] Optionally, the body portion 20a includes a first surface 23, a second surface 24, a third surface 25, and a fourth surface 26. The first limiting portion 20b is located on the second surface 24, and the second limiting portion 20c is located on the fourth surface 26.

[0155] Optionally, the main body 20a, the first limiting part 20b, and the second limiting part 20c are an integral structure. The main body 20a, the first limiting part 20b, and the second limiting part 20c are different parts of the same component. The main body 20a, the first limiting part 20b, and the second limiting part 20c can be formed by an integral molding process, such as metal injection molding, casting, or stamping.

[0156] In this embodiment, by providing a first limiting part 20b and a second limiting part 20c on the elastic member 20, the first limiting part 20b and the second limiting part 20c are respectively embedded in the covering layer 10. Through the cooperation of the first limiting part 20b, the second limiting part 20c and the covering layer 10, not only can the connection area between the elastic member 20 and the covering layer 10 be increased, but the elastic member 20 and the covering layer 10 can also form a snap-fit ​​structure, strengthening the connection between the elastic member 20 and the covering layer 10, making it less likely for the elastic member 20 and the covering layer 10 to separate, and the connector can withstand more repeated bending and has a longer service life.

[0157] Figure 19 This is a schematic diagram of the structure of an electronic device 200 according to an embodiment of this application.

[0158] Please see Figure 19 This application also provides an electronic device 200, which includes a first component 210, a connector 100 as described in this application, and a second component 220; the first component 210 is connected to one end of the connector 100, and the second component 220 is connected to the other end of the connector 100.

[0159] The electronic device 200 of this application can be, but is not limited to, headphones or other electronic devices 200 that require flexible connections between different components. In the embodiments of this application, the electronic device 200 is illustrated using headphones as an example, and should not be construed as a limitation on the electronic device 200 of the embodiments of this application.

[0160] Optionally, the headphones can be, but are not limited to, open-ear stereo headphones, over-ear headphones, neckband headphones, etc. Open-ear stereo headphones do not block the ear canal when worn, and transmit sound through air conduction / bone conduction, providing better comfort for long-term wear. Optionally, open-ear stereo headphones can be, but are not limited to, clip-on headphones and ear-hook headphones. In the accompanying drawings of this application, the headphones are illustrated using clip-on headphones as an example, which is only one form of headphones in this application and should not be construed as limiting the headphones in the embodiments of this application, nor should it be construed as limiting the connector 100 in the embodiments of this application. It should be noted that the main function of the connector 100 in the clip-on headphones is to provide a flexible connection and electrical connection between the first component 210 and the second component 220, and to achieve the ear-clamping function through the rebound force provided by the elastic member 20; the connector 100 of the ear-hook headphones has a larger spatial span and is mainly slender in shape, and the main function of the connector 100 is to hang on the ear.

[0161] Understandably, the first component 210, the connector 100, and the second component 220 are connected in sequence.

[0162] Optionally, the first component 210 is connected to the third end 11 of the connector 100, and the second component 220 is connected to the fourth end 12 of the connector 100.

[0163] It should be noted that the first component 210, the connector 100, and the second component 220 define a wearing space 230, which is used to wear the object on the target. Optionally, the target object can be, but is not limited to, at least one of a human ear, an ear model, a head, a head model, etc.

[0164] Optionally, the elastic member 20 extends from one end of the connector 100 near the first component 210 to one end of the connector 100 near the second component 220.

[0165] Optionally, the connector 100 has an arc-shaped structure, and the first component 210 and the second component 220 are respectively connected to the opposite ends of the connector 100, and the first component 210 and the second component 220 are located on the same side of the connector 100.

[0166] Optionally, the first component 210 is an acoustic part or a sound-emitting ball. The second component 220 is a clamping part, a battery part, or a battery bead.

[0167] Understandably, the first component 210 and the second component 220 are disposed opposite to each other. The first component 210, the connector 100 and the second component 220 are generally in the form of an arc-shaped structure, or a C-shaped structure, or a U-shaped structure, or a teardrop-shaped structure, etc.

[0168] It should be noted that when the electronic device 200 is an earphone, the first component 210 is used to produce sound. When the earphone is worn on a person's ear, the first component 210 is located in the concha of the ear, and the second component 220 is located at the back of the ear. That is, the first component 210 rests against the concha of the ear, and the second component 220 rests against the back of the ear. The initial distance between the first component 210 and the second component 220 is less than the minimum thickness of the ear. Therefore, the ear will spread the first component 210 and the second component 220 apart, increasing the distance between them. This increases the outward expansion force (i.e., tensile stress) applied to the opposite ends of the connector 100 (i.e., the third end 11 and the fourth end 12). The connector 100 includes an elastic element 20. When the opposite ends of the elastic element 20 (i.e., the first end 21 and the second end 22) expand outward, they generate an elastic restoring force that moves closer to each other (i.e., an elastic restoring force that returns to its natural state). Under the action of this elastic restoring force, the opposite ends of the connector 100 generate a clamping force that moves closer to each other (i.e., a clamping force is generated between the first component 210 and the second component 220). This causes the first component 210 and the second component 220 to clamp the opposite sides of the ear, making the earphone fit on the ear and less likely to fall off.

[0169] Understandably, when the electronic device 200 is an earphone, it has a wearing state and an unwearing state. When the electronic device 200 is in the wearing state, the elastic element 20 is in an expanded state; when the electronic device 200 is not in the wearing state, the elastic element 20 is in a natural or expanded state. When the electronic device 200 is worn, an outwardly expanding tensile stress is applied to the first component 210 and the second component 220. After the first end 21 and the second end 22 of the elastic element 20 are subjected to the outwardly expanding tensile stress, they will generate an elastic restoring force to return to their natural state, thereby causing the first component 210 and the second component 220 to generate an opposing clamping force. When the electronic device 200 is worn on a target object, this clamping force makes the first component 210 and the second component 220 firmly clamped on the target object.

[0170] The electronic device 200 of this application embodiment includes a first component 210, a connector 100 as described in this application, and a second component 220. The first component 210 is connected to one end of the connector 100, and the second component 220 is connected to the other end of the connector 100. The connector 100 includes a covering layer 10 and an elastic member 20. The elastic member 20 is embedded in the covering layer 10, and part of the elastic member 20 is visible. The visible part of the elastic member 20 can be part of the appearance of the connector 100, thereby giving the connector 100 a better appearance. In addition, the visible part of the elastic member 20 can also be designed through laser engraving, printing, or other processes, or additional decorative parts 30 can be assembled, thereby realizing diversified design of the appearance of the connector 100, breaking the monotony of the appearance design, and thus giving the connector 100 a better appearance.

[0171] Optionally, the electronic device 200 is an earphone. When the earphone is not worn, the first component 210 and the second component 220 can be positioned against each other or spaced apart.

[0172] Optionally, the electronic device 200 is an earphone. When the earphone is not worn, the distance between the first component 210 and the second component 220 ranges from 0mm to 18mm. Specifically, the distance between the first component 210 and the second component 220 can be, but is not limited to, 0mm, 1mm, 3mm, 4mm, 5mm, 6mm, 7mm, 8mm, 9mm, 10mm, 11mm, 12mm, 13mm, 14mm, 15mm, 16mm, 17mm, 18mm, etc. If the distance between the first component 210 and the second component 220 is too large when the earphone is not worn, the clamping force generated between the first component 210 and the second component 220 will be too small when the earphone is worn, making the earphone unstable and prone to falling off, thus affecting the user experience.

[0173] Optionally, the electronic device 200 is an earphone. When the earphone is in a wearing state, the clamping force between the first component 210 and the second component 220 ranges from 0.4N to 1.5N. Further, the clamping force between the first component 210 and the second component 220 ranges from 0.4N to 1.0N.
