Detailed Implementation

[0060] The technical solution of this application will now be clearly and completely described with reference to the accompanying drawings. Obviously, the embodiments described in this application are only a part of the embodiments, and not all of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments provided in this application without creative effort are within the protection scope of this application.

[0061] In this application, the reference to "embodiment" means that a specific feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor is it a mutually exclusive, independent, or alternative embodiment to other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described in this application can be combined with other embodiments.

[0062] 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 particular order. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion. For example, an assembly or device comprising one or more components is not limited to the one or more components listed, but may optionally also include one or more components not listed but inherent to the exemplified product, or one or more components that it should have based on the described function.

[0063] Please see Figure 1 and Figure 2 This application provides a connection component 100 with a certain elastic deformation capability. The connection component 100 can be applied to wearable devices with flexible connection structures, such as smart headphones, smart bracelets, and smart rings.

[0064] Please see Figure 1 and Figure 2 This embodiment uses the connection component 100 applied to an earphone 200 as an example. The earphone 200 includes, but is not limited to, clip-on earphones, TWS (True Wireless Stereo) earphones, ear-hook earphones, and behind-the-ear earphones. This embodiment uses the connection component 100 applied to a clip-on earphone as an example.

[0065] Please see Figures 3-6 The connecting component 100 includes a support member 10, an electrical connector 20, and a cover member 30.

[0066] The connecting component 100 has a certain elastic deformation capability, and the connecting component 100 can return to its initial state after deformation.

[0067] Optionally, the connecting component 100 may be in a straight line, an arc, a bend, a curve, or a spiral shape in its initial state. In this embodiment, the connecting component 100 is generally in a C-shaped bend as an example.

[0068] The support member 10 has a certain rigidity and a certain elastic deformation capacity. The support member 10 can return to its initial state after deformation, so that the connecting assembly 100 can maintain its initial state when not subjected to external force, deform after being subjected to external force, and return to its initial state after the external force is removed.

[0069] For example, the material of the support member 10 may include, but is not limited to, shape memory polymers, shape memory alloys, elastic metal alloys, or stainless steel, or the material of the support member 10 may include, but is not limited to, thermoplastic elastomers, or other polymeric materials. Support members 10 made of the above materials are capable of returning to their initial shape after elastic deformation.

[0070] Shape memory alloys include, but are not limited to, at least one of nickel-titanium based alloys, copper-based alloys, or iron-based alloys.

[0071] Electrical connector 20 includes, but is not limited to, at least one of the following: conductive wire, insulated wire, or flexible printed circuit (FPC) for transmitting electrical signals.

[0072] The electrical connector 20 is spaced apart from the support member 10. Optionally, the support member 10 and the electrical connector 20 can be separated by an air gap, or the support member 10 can be part of the covering member 30. The covering member 30 is spaced between the electrical connector 20 and the support member 10, protecting the electrical connector 20 from direct contact with the support member 10 and the electrical connector 20, reducing the risk of damage to the wires on the electrical connector 20, and improving the electrical connection stability of the electrical connector 20.

[0073] Please see Figures 3-6 The orthographic projection area of ​​the electrical connector 20 in the thickness direction Z at least partially overlaps with the orthographic projection area of ​​the support member 10 in the thickness direction Z. Here, the thickness direction Z refers to the direction from the inner bending side (-z) of the connecting assembly 100 to the outer bending side (+z).

[0074] Optionally, the orthographic projection area of ​​the electrical connector 20 in the thickness direction Z partially overlaps with the orthographic projection area of ​​the support member 10 in the thickness direction Z; even more optionally, the orthographic projection area of ​​the electrical connector 20 in the thickness direction Z completely overlaps with the orthographic projection area of ​​the support member 10 in the thickness direction Z.

[0075] When the connecting assembly 100 undergoes elastic deformation, the bending angle of the inner bending side -z of the connecting assembly 100 gradually increases or decreases. Since the support member 10 and the electrical connector 20 are at least partially opposite each other in the thickness direction Z, the support member 10 can absorb part of the force from the thickness direction Z by undergoing elastic deformation, so as to effectively block the influence of the force from the thickness direction Z on the electrical connector 20, thereby effectively avoiding stress damage and breakage of the electrical connector 20 during the deformation and use of the connecting assembly 100.

[0076] The material of the covering 30 can be a flexible material. Optionally, the hardness of the covering 30 is much lower than that of the support 10. The elastic modulus of the support 10 is much higher than that of the covering 30.

[0077] The material of the cover 30 includes, but is not limited to, at least one of silicone, rubber, or thermoplastic elastomer (TPE / TPU).

[0078] Please see Figure 3 The cover 30 surrounds the periphery of the electrical connector 20. For example, the cover 30 has excellent flexibility, bending resistance and resilience, and a gentle touch. The cover 30 can withstand repeated deformation during daily wear and quickly return to its original shape, effectively preventing the connector 100 from breaking.

[0079] Optionally, the cover 30 covers the periphery of the electrical connector 20 to protect the periphery of the electrical connector 20 from external hard contact damage or bending damage.

[0080] Optionally, the covering 30 surrounds and covers the entire periphery of the support 10. The support 10 is hidden within the covering 30. In other words, the entire periphery of the support 10 is hidden within the covering 30. Specifically, the thickness of the covering 30 on the outer periphery of the support 10 is relatively uniform, and no part of the support 10 is exposed on the outer surface of the covering 30. Taking the covering 30 as a roughly columnar shape as an example, the circumference around the central axis along the length direction of the covering 30 is defined as the periphery.

[0081] Furthermore, all the outer peripheral surfaces of the covering 30 are also all the outer peripheral surfaces of the connecting assembly 100. Taking the covering 30 as generally cylindrical as an example, the circumferential direction around the central axis along the length of the covering 30 is called the circumferential side. The circumferential surface around the central axis along the length of the covering 30 is called the outer peripheral side.

[0082] The covering 30 surrounds and covers the entire periphery of the support 10. On the one hand, it makes the outer surface of the connecting component 100 all flexible material, avoiding the abrupt feeling of different materials from different perspectives and to the touch. On the other hand, it facilitates the placement of the support 10 in the mold during the formation of the covering 30, and the injection of soft rubber or other flexible materials around the support 10 to form the covering 30. Furthermore, the covering 30 covering the entire periphery of the support 10 not only increases the bonding strength and firmness between the covering 30 and the support 10, but also provides flexible protection for the entire periphery of the support 10, preventing the effects of sweat or hard scratches.

[0083] Furthermore, the support member 10 provides the connecting assembly 100 with shaping capability and elastic deformation recovery capability, significantly improving its resistance to deformation. The covering member 30 covers the periphery of the support member 10, enabling the support member 10 to maintain stable support even after multiple bends.

[0084] The connection assembly 100 provided in this application includes a support member 10, an electrical connector 20, and a covering member 30. The electrical connector 20 and the support member 10 are spaced apart, and the orthographic projection area of ​​the electrical connector 20 in the thickness direction Z at least partially overlaps with the orthographic projection area of ​​the support member 10 in the thickness direction Z. The covering member 30 surrounds the periphery of the electrical connector 20 and encloses the entire periphery of the support member 10. The support member 10 is hidden in the covering member 30. The covering member 30 provides a soft covering for the electrical connector 20 and the support member 10, giving the connection assembly 100 a certain elastic deformation capability. The support member 10 can protect the electrical connector 20 in the thickness direction Z, thereby reducing the deformation stress on the electrical connector 20 during the elastic deformation of the connection assembly 100, reducing the risk of breakage of the internal wires during the elastic deformation of the connection assembly 100, and improving stability.

[0085] The following examples, with reference to the accompanying drawings, illustrate the positional and width relationships between the electrical connector 20 and the support member 10 provided in this application.

[0086] Optional, please refer to Figures 3-6 The support member 10 is arc-shaped in the length direction. The support member 10 is generally a long arc-shaped strip. The support member 10 extends in an arc shape.

[0087] Please see Figures 3-6 The electrical connector 20 is arc-shaped along its length. The electrical connector 20 is generally a long, arc-shaped strip. The electrical connector 20 extends in an arc shape. The arc-shaped extension curve of the electrical connector 20 may be conformal or non-conformal with the arc-shaped extension curve of the support member 10.

[0088] Please see Figures 3-6The covering member 30 is arc-shaped in the length direction. The covering member 30 is generally a long arc-shaped strip. The covering member 30 extends in an arc shape. The arc-shaped extension curve of the covering member 30 may be conformal or non-conformal with the arc-shaped extension curve of the support member 10.

[0089] This application does not specifically limit the shape of the connecting component 100. When the connecting component 100 is applied to a wearable device, the connecting component 100 has an ergonomic curved shape for easy wearing. Specifically, when the connecting component 100 is applied to clip-on headphones, the shape of the connecting component 100 is ergonomic and can fit the ear bridge.

[0090] Optionally, the number of support members 10 along the extension direction may be one, and the extension length (arc length) of the one support member 10 is similar to or the same as the extension length (arc length) of the electrical connector 20.

[0091] Alternatively, the number of support members 10 along the extension direction can be two or more, with multiple support members 10 arranged sequentially in the extension direction. Multiple support members 10 can be spaced apart, which can protect the electrical connector 20, reduce the resistance to deformation of the connection assembly 100, and maintain good deformation recovery force after the deformation force is removed.

[0092] Optionally, at least a portion of the support member 10 is located on the inner curved side -z of the electrical connector 20. Specifically, all of the support members 10 are located on the inner curved side -z of the electrical connector 20; or, a portion of the support member 10 is located on the inner curved side -z of the electrical connector 20, and another portion of the support member 10 is located on other sides of the electrical connector 20 (e.g., the side in the width direction X, or the outer curved side +z, etc.).

[0093] Understandably, when the connecting component 100 undergoes elastic deformation, the tensile or torsional stress on the inner bending side -z of the electrical connector 20 is relatively concentrated. These stresses may cause the electrical connector 20 to break or its wires to break. Based on this, this embodiment designs at least a portion of the support member 10 to be located on the inner bending side -z of the electrical connector 20. Since the support member 10 has a certain stress absorption capacity (e.g., converting tensile / shear stress into reversible changes in crystal structure), it can effectively resist the influence of the tensile or torsional stress on the inner bending side -z of the electrical connector 20 on the electrical connector 20, thereby effectively avoiding the risk of breakage of the internal wires of the electrical connector 20 during deformation.

[0094] In other words, the support member 10 provided in this embodiment not only provides the connecting assembly 100 with stable elastic deformation recovery capability, significantly improving its resistance to deformation, but also serves as a stress protection component for the electrical connector 20 during bending deformation. The support member 10 disperses the concentrated stress generated during bending through its high elastic modulus, preventing the substrate or copper wires in the electrical connector 20 from breaking. The support member 10 protects the electrical connector 20; for example, it can be reused as a reinforcing plate for the electrical connector 20 to protect it and prevent it from being severely bent and damaged.

[0095] Of course, in other embodiments, at least a portion of the support member 10 is disposed on one or both sides of the electrical connector 20 in the width direction X; of course, in other embodiments, at least a portion of the support member 10 is disposed on the outer curved side +z of the electrical connector 20. Specific examples of the support member 10's structure will be provided later.

[0096] In one alternative implementation, please refer to Figure 7 and Figure 8 At least a portion of the edge of the electrical connector 20 extending along the length direction is projected onto the thickness direction Z by the orthogonal projection of the support 10 onto the thickness direction Z.

[0097] Specifically, the orthographic projection of part or all of the edge of the electrical connector 20 extending along the length direction in the thickness direction Z is located within the orthographic projection area of ​​the support 10 in the thickness direction Z.

[0098] Further, please refer to Figure 9 The electrical connector 20 includes a first edge 21 and a second edge 22 extending along the length direction, wherein the first edge 21 and the second edge 22 are spaced apart along the width direction X.

[0099] Optional, please refer to Figure 9 The orthographic projection of all the first edges 21 of the electrical connector 20 in the thickness direction Z lies within the orthographic projection region of the support 10 in the thickness direction Z. For example, the first edge 21 is Figure 9The left edge of the electrical connector 20. That is, the orthographic projection of the entire left edge of the electrical connector 20 in the thickness direction Z lies within the orthographic projection area of ​​the support member 10 in the thickness direction Z. In other words, the left edge of the support member 10 extends relative to the entire left edge of the electrical connector 20. Thus, when the connecting assembly 100 undergoes tensile or torsional deformation, the left edge of the support member 10 can resist stress from the left side, effectively protecting the left side of the electrical connector 20 and reducing stress damage caused by left-side stress. The support member 10 can also resist stress from the inner bending side -z, effectively protecting the inner bending side -z of the electrical connector 20 and reducing stress damage caused by inner bending side -z stress. The support member 10 disperses the concentrated stress generated during bending through its high elastic modulus, preventing the substrate or copper wire in the electrical connector 20 from breaking.

[0100] Alternatively, the orthographic projection of a portion of the first edge 21 of the electrical connector 20 in the thickness direction Z is located within the orthographic projection area of ​​the support 10 in the thickness direction Z, while the orthographic projection of the other portion of the first edge 21 in the thickness direction Z is located outside the orthographic projection area of ​​the support 10 in the thickness direction Z.

[0101] Optional, please refer to Figure 10 The orthographic projection of the entire second edge 22 of the electrical connector 20 in the thickness direction Z lies within the orthographic projection region of the support 10 in the thickness direction Z. For example, the second edge 22 is... Figure 10 The right edge of the electrical connector 20. That is, the orthographic projection of the entire right edge of the electrical connector 20 in the thickness direction Z lies within the orthographic projection area of ​​the support member 10 in the thickness direction Z. In other words, the right edge of the support member 10 extends relative to the entire right edge of the electrical connector 20. Thus, when the connecting assembly 100 undergoes tensile or torsional deformation, the right edge of the support member 10 can resist stress from the right side, effectively protecting the right side of the electrical connector 20 and reducing stress damage caused by right-side stress. The support member 10 can also resist stress from the inner bending side -z, effectively protecting the inner bending side -z of the electrical connector 20 and reducing stress damage caused by inner bending side -z stress. The support member 10 disperses the concentrated stress generated during bending through its high elastic modulus, preventing the substrate or copper wire in the electrical connector 20 from breaking.

[0102] Alternatively, the orthographic projection of a portion of the second edge 22 of the electrical connector 20 in the thickness direction Z is located within the orthographic projection area of ​​the support 10 in the thickness direction Z, while the orthographic projection of another portion of the second edge 22 in the thickness direction Z is located outside the orthographic projection area of ​​the support 10 in the thickness direction Z.

[0103] This embodiment designs at least a portion of the edge of the electrical connector 20 extending along its length direction to have its orthographic projection in the thickness direction Z located within the orthographic projection of the support member 10 in the thickness direction Z. The support member 10 can protect not only one side of the electrical connector 20 in the thickness direction Z, but also one or both sides of the electrical connector 20 in the width direction X, improving the effective protection of the electrical connector 20 on multiple sides and reducing stress damage and breakage problems during repeated bending. The support member 10, with its high elastic modulus, disperses the concentrated stress generated during bending, preventing breakage of the substrate or copper wires in the electrical connector 20.

[0104] In one alternative embodiment, the width of the electrical connector 20 is less than or equal to the width of the support 10.

[0105] Optional, please refer to Figure 9 The orthographic projection of the first edge 21 of the electrical connector 20 lies within the orthographic projection area of ​​the support 10, while the orthographic projection of the second edge 22 of the electrical connector 20 lies outside the orthographic projection area of ​​the support 10. Thus, the support 10 can effectively resist deformation stress from the side where the first edge 21 is located and the inner bending side -z, thereby protecting the side where the first edge 21 is located and the inner bending side -z of the electrical connector 20.

[0106] Furthermore, the support member 10 is arc-shaped in the length direction, and the electrical connector 20 is located on the outside of the curve of the support member 10.

[0107] When the connecting assembly 100 undergoes bending or torsional deformation, the tensile or torsional stress on the inner side (-z) of the bending of the electrical connector 20 is relatively concentrated. In this embodiment, by placing the electrical connector 20 on the outer side of the bending of the support member 10, and with the width of the electrical connector 20 being less than or equal to the width of the support member 10, the support member 10 can act as a stress protector for the electrical connector 20 during bending or torsional deformation. The support member 10, through its high elastic modulus, disperses the concentrated stress generated during bending, preventing breakage of the substrate or copper wires in the electrical connector 20. The support member 10 serves to protect the electrical connector 20; for example, it can function as a reinforcing plate for the electrical connector 20, protecting it from significant bending damage.

[0108] Understandably, when the electrical connector 20 is bent mainly on the inner side -z and the side where the first edge 21 is located, the orthographic projection of the second edge 22 of the electrical connector 20 can be located outside the orthographic projection area of ​​the support member 10. In addition to effectively protecting the side where the bending stress of the electrical connector 20 is located, the width of the support member 10 can be shortened as much as possible to form a connection assembly 100 with a relatively small width dimension.

[0109] Alternatively, please refer to Figure 10 The orthographic projection of the second edge 22 of the electrical connector 20 lies within the orthographic projection area of ​​the support 10, while the orthographic projection of the first edge 21 of the electrical connector 20 lies outside the orthographic projection area of ​​the support 10. Thus, the support 10 can effectively resist deformation stress from the side where the second edge 22 is located and the inner bending side -z, thereby protecting the side where the second edge 22 is located and the inner bending side -z of the electrical connector 20.

[0110] Understandably, when the electrical connector 20 is bent mainly on the inner side -z and the side where the second edge 22 is located, the orthographic projection of the first edge 21 of the electrical connector 20 can be located outside the orthographic projection area of ​​the support member 10. In addition to effectively protecting the side where the bending stress of the electrical connector 20 is located, the width of the support member 10 can be shortened as much as possible to form a connection assembly 100 with a relatively small width dimension.

[0111] Alternatively, please refer to Figure 11 The orthographic projection of the first edge 21 of the electrical connector 20 lies within the orthographic projection area of ​​the support 10, and the orthographic projection of the second edge 22 of the electrical connector 20 lies within the orthographic projection area of ​​the support 10. Thus, the support 10 can effectively resist deformation stress from the side where the second edge 22 is located, the side where the first edge 21 is located, and the inner bending side -z, protecting the electrical connector 20 from deformation stress. Furthermore, the support 10 provides multi-sided protection for the electrical connector 20, providing sufficient strength for the entire electrical connector 20 and further reducing the risk of deformation fracture. The support 10, through its high elastic modulus, disperses the concentrated stress generated during bending, preventing breakage of the substrate or copper wires in the electrical connector 20.

[0112] Optional, please refer to Figure 12 The width of the electrical connector 20 is greater than the width of the support 10.

[0113] Optionally, the orthographic projection of the first edge 21 of the electrical connector 20 is located within the orthographic projection area of ​​the support 10, and the orthographic projection of the second edge 22 of the electrical connector 20 is located outside the orthographic projection area of ​​the support 10. In this way, the support 10 can effectively resist the deformation stress from the side where the first edge 21 is located and the inner bending side -z, so as to protect the side where the first edge 21 is located and the inner bending side -z of the electrical connector 20.

[0114] Understandably, when the electrical connector 20 is bent mainly on the inner side -z and the side where the first edge 21 is located, the orthographic projection of the second edge 22 of the electrical connector 20 can be located outside the orthographic projection area of ​​the support member 10. In addition to effectively protecting the side where the bending stress of the electrical connector 20 is located, the width of the support member 10 can be shortened as much as possible to form a connection assembly 100 with a relatively small width dimension.

[0115] Alternatively, the orthographic projection of the second edge 22 of the electrical connector 20 is located within the orthographic projection area of ​​the support 10, while the orthographic projection of the first edge 21 of the electrical connector 20 is located outside the orthographic projection area of ​​the support 10. In this way, the support 10 can effectively resist deformation stress from the side where the second edge 22 is located and the inner bending side -z, thereby protecting the side where the second edge 22 is located and the inner bending side -z of the electrical connector 20.

[0116] Understandably, when the electrical connector 20 is bent mainly on the inner side -z and the side where the second edge 22 is located, the orthographic projection of the first edge 21 of the electrical connector 20 can be located outside the orthographic projection area of ​​the support member 10. In addition to effectively protecting the side where the bending stress of the electrical connector 20 is located, the width of the support member 10 can be shortened as much as possible to form a connection assembly 100 with a relatively small width dimension.

[0117] Alternatively, please refer to Figure 12 The orthographic projection of the first edge 21 of the electrical connector 20 is outside the orthographic projection area of ​​the support 10, and the orthographic projection of the second edge 22 of the electrical connector 20 is also outside the orthographic projection area of ​​the support 10. Thus, the support 10 can effectively resist deformation stress from the inner bending side -z, protecting the inner bending side -z of the electrical connector 20 and reducing the risk of deformation fracture of the electrical connector 20; it can also minimize the width of the support 10, thereby reducing the cross-sectional area of ​​the connecting assembly 100.

[0118] For example, for some connecting components 100 with flat, elliptical, or crescent-shaped cross-sections, by placing the electrical connector 20 in a position where the width of the connecting component 100 is relatively wide, and further placing the support member 10 in a position where the width is relatively small, it is possible to satisfy the stress resistance and effective protection of the support member 10 for the electrical connector 20 in the thickness direction Z (e.g., the inner side of the bend -z), and also to make full use of the relatively narrow space in the connecting component 100, so that the overall width of the connecting component 100 is relatively short. This reduces the clamping area and improves the wearing comfort of the headphones while ensuring that the headphones have a certain clamping force.

[0119] The shape of the support member 10 will be illustrated in detail below with reference to the accompanying drawings.

[0120] For the first alternative implementation, please refer to Figure 13 The support member 10 includes a support piece 10a. The support piece 10a and the electrical connector 20 are disposed opposite each other in the thickness direction Z.

[0121] For example, the support member 10 may include, but is not limited to, a shape memory structure. As a further example, the support member 10 may include, but is not limited to, a shape memory metal.

[0122] The support sheet 10a includes, but is not limited to, a shape memory metal sheet. The electrical connector 20 includes, but is not limited to, a flexible circuit board or an insulated conductive wire.

[0123] When the connecting assembly 100 is bent, stress concentration easily forms in the thickness direction Z. The support piece 10a, with its high elastic modulus, disperses the concentrated stress generated during bending of the connecting assembly 100, effectively protecting the electrical connector 20 in the thickness direction Z and preventing breakage of the substrate or copper wire of the electrical connector 20. The support piece 10a also absorbs some of the alternating stress through micro-plastic deformation, delaying substrate fatigue. The shape memory metal sheet's superelastic effect can offset most of the bending energy, maintaining circuit stability when the connecting assembly 100 is repeatedly bent. In addition, the sheet-like support piece 10a also has good resistance to lateral torsion, reducing torsional deformation damage to the electrical connector 20.

[0124] Optionally, the support sheet 10a may be, but is not limited to, a solid sheet. Further optionally, the surface of the support sheet 10a may be provided with microgrooves or a mesh design, so as not only to resist stress in the thickness direction Z, but also to form a multi-directional stress buffer zone during torsion, so as to avoid stress concentration that could cause the copper foil or copper wire on the electrical connector 20 to break.

[0125] Alternatively, the support sheet 10a may include, but is not limited to, at least one of the following: mesh (with mesh holes including but not limited to square holes, diamond holes, triangular holes, rectangular holes, etc.) or fishbone shape, so as not only to resist stress in the thickness direction Z, but also to form a multi-directional stress buffer zone during torsion, so as to avoid stress concentration causing the copper foil or copper wire on the electrical connector 20 to break.

[0126] Optionally, the thickness of the support sheet 10a can be uniform or non-uniform. Non-uniform thickness includes, but is not limited to, being thicker at both edges and thinner in the middle, so that the support sheet 10a can form gradient support when bent, which can prevent excessive deformation and maintain overall flexibility.

[0127] For the second alternative implementation, please refer to... Figure 14 The support member 10 includes a plurality of support bars 10b. The plurality of support bars 10b are spaced apart along the width direction X. In other words, the support member 10 is in the form of a grid.

[0128] The covering 30 partially fills the spaces between adjacent support bars 10b. Adjacent support bars 10b may or may not be connected.

[0129] The shielding area ratio (protection area ratio) of the multiple support bars 10b to the electrical connector 20 is more than 50%. The multiple support bars 10b are spaced apart from the electrical connector 20 in the thickness direction Z, forming stress-retaining strips on the electrical connector 20 in the thickness direction Z. Through the regularly arranged gaps between the bars, concentrated stress is distributed to the multiple support bars 10b, preventing localized stress concentration from causing tearing of the substrate or breakage of the wires in the electrical connector 20. When the connector assembly 100 is bent, due to the relatively small cross-sectional size of the support bars 10b, they can more smoothly undergo torsional deformation. The support bars 10b absorb shear force through micro-sliding and elastic deformation, reducing the copper foil breakage rate of the electrical connector 20 under torsion.

[0130] This application does not specify the number and spacing of the support bars 10b. The cross-section of the support bars 10b includes, but is not limited to, at least one of the following: circular, square, triangular, rhomboid, elliptical, irregular shape, etc.

[0131] Optionally, the thickness of the multiple support strips 10b can be uniform or non-uniform. Non-uniform thickness includes, but is not limited to, the support strips 10b on both edges being relatively thick and the support strips 10b in the middle being relatively thin, so as to facilitate the formation of gradient support when the multiple support strips 10b are bent, which can prevent excessive deformation and maintain overall flexibility.

[0132] For a third alternative implementation, please refer to... Figure 15 The support member 10 includes a plurality of first sub-support members 11. The plurality of first sub-support members 11 are arranged sequentially along the thickness direction Z.

[0133] This application does not specify the number of the first sub-support members 11. For example, the number of the first sub-support members 11 may be two, three, or four, etc.

[0134] The first sub-support member 11 may be the support piece 10a in the first optional embodiment described above or a plurality of support bars 10b arranged along the width direction X in the second optional embodiment described above.

[0135] Please see Figure 16When the first sub-support 11 consists of multiple support bars 10b arranged along the width direction X, two adjacent rows of support bars 10b along the thickness direction Z can be staggered in the width direction X. That is, the upper row of support bars 10b is directly opposite the gap between the adjacent support bars 10b in the lower row, so that the two rows of support bars 10b have a large blocking area in the thickness direction Z. Moreover, since the cross-sectional size of the support bars 10b is relatively small, the support bars 10b can generate torsional deformation more smoothly. The support bars 10b absorb shear force through micro-sliding and elastic deformation, reducing the copper foil breakage rate of the electrical connector 20 under torsion.

[0136] This application does not specify the exact position of the first sub-support 11 within the covering 30.

[0137] Optional, please refer to Figures 17a-17h At least one of the first sub-support members 11 is located on the outer +z side of the bend of the electrical connector 20; and / or, at least one of the first sub-support members 11 is located on the inner -z side of the bend of the electrical connector 20; and / or, at least one of the first sub-support members 11 and the electrical connector 20 are arranged along the width direction X; and / or, at least one of the first sub-support members 11, the electrical connector 20 and at least another first sub-support member 11 are arranged sequentially along the width direction X.

[0138] For example, please see Figure 17a Multiple first sub-supports 11 are located on the same side of the electrical connector 20, which is either the outer side of the bend +z, the inner side of the bend -z, or the left side of the width direction X, or the right side of the width direction X, or any other side.

[0139] For example, please see Figures 17b-17c Multiple first sub-support members 11 are located on both sides of the electrical connector 20. These two sides are either the outer side of the bend +z, the inner side of the bend -z, or the left side of the width direction X, or the right side of the width direction X, or any other side.

[0140] For example, please see Figures 17d-17g Multiple first sub-support members 11 are located on three sides of the electrical connector 20, which are any three sides of the outer side of the bend +z, the inner side of the bend -z, or the left side of the width direction X, or the right side of the width direction X, or any other side.

[0141] For example, please see Figure 17h Multiple first sub-support members 11 are located on four sides of the electrical connector 20. These four sides are any four sides of the outer side of the bend +z, the inner side of the bend -z, or the left side of the width direction X, or the right side of the width direction X, or any other side.

[0142] This application, by designing multiple spaced first sub-support members 11, can not only form protection on one side, multiple sides, or all directions around the electrical connector 20, but also, because the first sub-support members 11 are spaced apart, the torsional resistance of the multiple first sub-support members 11 when the connecting assembly 100 is torn is relatively small, so that the connecting assembly 100 can be torn flexibly and return to its initial state after the torsional force is removed.

[0143] Optional, please refer to Figure 18 The support member 10 includes a first sub-support portion 12, a second sub-support portion 13, and a third sub-support portion 14 connected sequentially along the width direction X. At least a portion of the first sub-support portion 12 is opposite to at least a portion of the third sub-support portion 14. Optionally, the cross-section of the support member 10 is generally U-shaped.

[0144] The second sub-support 13 is disposed opposite to the electrical connector 20 in the thickness direction Z. The second sub-support 13 can effectively protect the electrical connector 20 from stress in the thickness direction Z, avoiding stress concentration in the thickness direction Z, which could lead to breakage of the electrical connector 20 substrate or wire. Further optionally, the second sub-support 13 can be disposed on the inner side -z of the bend of the electrical connector 20.

[0145] The first sub-support portion 12 and the third sub-support portion 14 are respectively disposed on both sides of the electrical connector 20 in the width direction X. The first sub-support portion 12 and the third sub-support portion 14 can effectively protect against stress in the width direction X of the electrical connector 20, avoiding stress concentration in the width direction X, which could lead to breakage of the electrical connector 20 substrate or wire.

[0146] Generally, when the connecting component 100 is stretched or twisted, the main stress comes from the thickness direction Z and the width direction X. In this embodiment, through the above design, the support member 10 can effectively protect the electrical connector 20 from stress when the connecting component 100 is stretched or twisted, and avoid stress concentration that could cause the base material of the electrical connector 20 to break or the wire to break.

[0147] Furthermore, there can be multiple support members 10, which can be arranged around the periphery of the electrical connector 20 to provide all-round protection for the periphery of the electrical connector 20. Multiple support members 10 can be arranged sequentially along the extending direction.

[0148] In other embodiments, the cross-section of the support member 10 may also be C-shaped or L-shaped, etc.

[0149] Further optional information can be found in [link to relevant documentation]. Figure 19a and Figure 19bThe first sub-support portion 12 is provided with a plurality of first notches 15 at its edge away from the second sub-support portion 13; and / or, the third sub-support portion 14 is provided with a plurality of second notches 16 at its edge away from the second sub-support portion 13.

[0150] The first notch 15 provides deformation space to reduce the torsional resistance of the support member 10, allowing the connecting assembly 100 to be stretched and twisted more flexibly, and to return to its initial state after being stretched or twisted. The second notch 16 provides deformation space to reduce the torsional resistance of the support member 10, allowing the connecting assembly 100 to be stretched and twisted more flexibly, and to return to its initial state after being stretched or twisted, thus giving the support member 10 good tensile and torsional deformation capabilities.

[0151] Furthermore, the first notch 15 can extend to the second sub-support 13, so that the middle of the second sub-support 13 retains the main branch along the extension direction, and the two sides of the main branch are multiple secondary branches connected to the main branch. The secondary branch on one side of the main branch extends from the inner side of the bend of the electrical connector 20 -z to the left side of the width direction X; the secondary branch on the other side of the main branch extends from the inner side of the bend of the electrical connector 20 -z to the right side of the width direction X.

[0152] Optional, please refer to Figure 20 The support member 10 is disposed around the periphery of the electrical connector 20. In this way, the support member 10 provides all-round protection to the periphery of the electrical connector 20 when the connecting assembly 100 deforms. With its high elastic modulus, the support member 10 absorbs stress from the periphery of the electrical connector 20, thereby further reducing the risk of breakage during the deformation or bending process of the connecting assembly 100 under pressure.

[0153] Optional, please refer to Figure 20 At least a portion of the support member 10 is tubular. Further optionally, the support member 10 may be, but is not limited to, a mesh tube, a solid tube, a tube with notches or through holes in its wall, or a segmented connecting tube. The surface of the support member 10 has some notches or through holes to provide deformation space, reduce deformation resistance, and enable the connecting assembly 100 to have both flexibility and deformation recovery capability; and / or, the support member 10 is helical, and the electrical connector 20 is located at the helical center of the helical support member 10.

[0154] This embodiment designs the support member 10 to be tubular or spiral, etc., and surrounds the periphery of the electrical connector 20. This allows the support member 10 to provide all-round protection to the periphery of the electrical connector 20 when the connecting assembly 100 deforms. With its high elastic modulus, the support member 10 absorbs stress from the periphery of the electrical connector 20, thereby further reducing the risk of breakage during the deformation or bending process of the connecting assembly 100 under pressure. Furthermore, the support member 10 is both flexible and has deformation recovery capability, thus enabling the connecting assembly 100 to have both flexibility and deformation recovery capability.

[0155] The positional relationship between the cover 30 and the electrical connector 20 is illustrated below with reference to the accompanying drawings.

[0156] Optional, please refer to Figures 8-20 The cover 30 has a wire hole 31. The electrical connector 20 passes through the wire hole 31.

[0157] The covering 30 is arc-shaped. The wire hole 31 is arc-shaped. The support 10 is arc-shaped. The arc-shaped extension curve of the covering 30 and the arc-shaped extension line of the support 10 may be conformal or approximately conformal. The arc-shaped extension curve of the wire hole 31 and the arc-shaped extension line of the support 10 may be conformal or approximately conformal.

[0158] The cover 30 and the support 10 can be integrated into a single structure through injection molding. Before injection molding, a contoured metal sheet with the same shape as the wire hole 31 is inserted. Then, the contoured metal sheet and the support 10 are injection molded together with soft rubber. After the contoured metal sheet is removed, a hollow wire hole 31 is created inside the cover 30. During assembly, the electrical connector 20 is passed through the wire hole 31.

[0159] Optional, please refer to Figure 11 The distance between the outer peripheral surface of the electrical connector 20 and the wall of the wire hole 31 is greater than or equal to a first preset distance. For example, the first preset distance is 0 mm to 0.5 mm, but is not limited to this data. Further optionally, the distance between the outer peripheral surface of the electrical connector 20 and the wall of the wire hole 31 can be between 0.1 mm and 0.5 mm.

[0160] In this embodiment, the hole shape of the wire hole 31 is designed to be 0.1mm-0.5mm larger than the outer dimensions of the electrical connector 20. Furthermore, the distance between the hole wall of the wire hole 31 and the outer peripheral surface of the electrical connector 20 is greater than or equal to 0.1mm-0.5mm. This ensures that the electrical connector 20 can smoothly pass through the wire hole 31, guaranteeing the assembleability of subsequent wiring, while also preventing the wire hole 31 from being too large, thus minimizing the cross-sectional dimensions of the connecting assembly 100.

[0161] Further optional information can be found in [link to relevant documentation]. Figure 11 The covering 30 surrounds and adheres to the peripheral side of the support 10. For example, the covering 30 is a soft material (such as silicone, rubber, thermoplastic polyurethane, etc.), and the support 10 has a high elastic modulus, such as shape memory metal. The soft material completely covers the shape memory metal, and the soft material layer absorbs bending energy through elastic deformation, uniformly dispersing the concentrated stress acting on the shape memory metal (such as nickel-titanium based materials), significantly reducing the risk of microcracks caused by repeated phase transformations of the shape memory metal, and extending its service life. When the shape memory metal undergoes an austenite-martensite phase transformation during bending, the soft material can act as a buffer layer to reduce lattice distortion damage during the phase transformation process and avoid fatigue fracture caused by high-frequency deformation of the shape memory metal.

[0162] Optional, please refer to Figure 11 The electrical connector 20 includes a flexible circuit board 23. The flexible circuit board 23 and the support member 10 are disposed opposite each other in the thickness direction Z. Taking the support member 10 as a support sheet 10a as an example, both the flexible circuit board 23 and the support sheet 10a are thin-layer structures. The flexible circuit board 23 and the support sheet 10a can be disposed face-to-face. Further, the width direction X of the flexible circuit board 23 is parallel or nearly parallel to the width direction X of the support sheet 10a, and the width direction X of the flexible circuit board 23 is parallel or nearly parallel to the width direction X of the covering member 30.

[0163] Since both the flexible circuit board 23 and the support sheet 10a have relatively large dimensions in the width direction X and relatively small dimensions in the thickness direction Z, the size of the covering part 30 in the thickness direction Z can be designed to be smaller than the size in the width direction X. That is, the covering part 30 can be flat or elliptical, so that while covering the periphery of the flexible circuit board 23 and the support sheet 10a, the covering part 30 also has a relatively small thickness, which is beneficial for the connecting assembly 100 to have better elasticity and bend more easily.

[0164] Optional, please refer to Figure 6 The electrical connector 20 includes a flexible circuit board 23. The flexible circuit board 23 includes a connecting end 231, a middle section 232, and a wire-passing end 234 connected sequentially along its length.

[0165] The middle section 232 is the part that passes through the wire hole 31. The wire end 234 is the part that passes through the wire hole 31.

[0166] Please see Figure 21The threaded end 234 has a first end side 234a and a second end side 234b arranged opposite to each other along the width direction X. The intermediate section 232 has a first intermediate section side 232a and a second intermediate section side 232b arranged opposite to each other along the width direction X. The first end side 234a and the first intermediate section side 232a are located on the same side and can be collinear; or, the first end side 234a and the first intermediate section side 232a are close in distance along the width direction X. The second end side 234b and the second intermediate section side 232b are located on the same side and can be collinear; or, the second end side 234b and the second intermediate section side 232b are close in distance along the width direction X.

[0167] Thus, when the electrical connector 20 is in a flattened state, the wire end 234 is not bent relative to the middle section 232, and the width of the wire end 234 is the same as or similar to the width of the middle section 232. Both the wire end 234 and the middle section 232 can be smoothly inserted into the wire hole 31. Furthermore, the wire end 234 can smoothly exit through the wire hole 31. If the wire end 234 were bent relative to the middle section 232 when exiting through the wire hole 31, the wire hole 31 might need to be larger to accommodate both the wire end 234 and the middle section 232 simultaneously, or the electrical connector 20 might not be able to exit smoothly.

[0168] After the thread end 234 passes through the thread hole 31, the thread end 234 can be bent toward the inner side of the bend relative to the middle section 232. A part of the thread end 234 abuts against the outside of the cover 30 to prevent the thread end 234 from retracting into the thread hole 31 again.

[0169] This application does not specifically limit whether the connection end 231 of the electrical connector 20 is bent relative to the middle section 232 (when the electrical connector 20 is in a flattened state).

[0170] Optionally, the connecting end 231 is bent relative to the middle section 232 when the electrical connector 20 is in a flattened state, so that the connecting end 231 is located outside one end of the covering 30, thereby limiting the position of the connecting end 231 of the electrical connector 20.

[0171] When the electrical connector 20 is in a flattened state, the connecting end 231 is bent relative to the middle section 232, and after the wire end 234 passes through the wire hole 31, the wire end 234 may be bent toward the inside of the bend relative to the middle section 232 to confine the middle section 232 within the wire hole 31.

[0172] Optionally, the electrical connector 20 includes a flexible circuit board 23. As the number of wires required for the connection assembly 100 increases, by configuring the electrical connector 20 as a flexible circuit board 23, a larger number of wires can be arranged on the flexible circuit board 23 to meet the needs of more wire layouts.

[0173] Please see Figure 21 One end of the flexible circuit board 23 (as described above, the wire end 234) has multiple pads 235.

[0174] For the first alternative implementation, please refer to Figure 22 The multiple pads 235 are arranged in multiple rows, and the pads 235 in adjacent rows are staggered to provide a greater number of pads 235 in a limited area to meet the layout requirements of a larger number of wires in the flexible circuit board 23.

[0175] For the second alternative implementation, please refer to... Figure 23 Multiple pads 235 are arranged along the length of the edge of the flexible circuit board 23. A portion of the pads 235 are arranged along the length of the first edge 21 of the flexible circuit, and another portion of the pads 235 are arranged along the length of the second edge 22 of the flexible circuit, so as to provide a greater number of pads 235 in a limited area to meet the layout requirements of a larger number of wires in the flexible circuit board 23.

[0176] For a third alternative implementation, please refer to... Figure 24 Multiple pads 235 are arranged along the width direction X at the end edge of the flexible circuit board 23 to provide a greater number of pads 235 in a limited area to meet the layout requirements of a larger number of wires in the flexible circuit board 23.

[0177] Optionally, the support member 10 includes a shape memory structure, and the support member 10 has a certain rigidity and a certain elastic deformation capacity. The support member 10 can return to its initial state after deformation, so that the connecting assembly 100 can maintain its initial state when not subjected to external force, deform after being subjected to external force, and return to its initial state after the external force is removed.

[0178] For example, the material of the support member 10 includes, but is not limited to, shape memory polymers, shape memory alloys, elastic metal alloys, or stainless steel, or the material of the support member 10 includes, but is not limited to, thermoplastic elastomers, or other polymeric materials. Support members 10 made of the above materials enable the support to return to its initial shape after elastic deformation.

[0179] Shape memory alloys include, but are not limited to, at least one of nickel-titanium based alloys, copper-based alloys, or iron-based alloys.

[0180] Optionally, the electrical connector 20 includes insulated wires. The electrical connector 20 also includes, but is not limited to, at least one of conductive wires or wires used for transmitting electrical signals in an FPC (flexible printed circuit board 23).

[0181] Optional, please refer to Figures 4-8 The connecting component 100 also includes a first mounting end 41 and a second mounting end 42.

[0182] The first mounting end 41 and the second mounting end 42 are fixedly connected to the two ends of the support member 10, respectively.

[0183] The material of the first mounting end 41 includes, but is not limited to, hard plastic or metal alloy. The material of the second mounting end 42 includes, but is not limited to, hard plastic or metal alloy.

[0184] Please see Figure 5 The two ends of the covering 30 are fixedly connected to the first mounting end 41 and the second mounting end 42, respectively. The first mounting end 41 has a first mounting hole 411. The second mounting end 42 has a second mounting hole 412. The two ends of the wire hole 31 are respectively connected to the first mounting hole 411 and the second mounting hole 412. The electrical connector 20 is sequentially inserted into the first mounting hole 411, the wire hole 31, and the second mounting hole 412.

[0185] The fixing method between the support member 10 and the first mounting end 41 and the second mounting end 42 includes, but is not limited to, firstly, injection molding the shaped memory metal sheet (support member 10) and the plastic hard plastic or metal alloy at both ends (first mounting end 41 and second mounting end 42) into a whole, thus strongly fixing the two ends of the support member 10 to the first mounting end 41 and the second mounting end 42. Then, before injection molding the soft plastic shell (covering part 30), the conformal metal sheet is inserted into the wire hole 31 reserved on both sides of the plastic hard plastic or metal alloy (first mounting end 41 and second mounting end 42), and then the component is injection molded together with soft plastic covering. After the covering injection molding is completed, the shape of the connecting component 100 is completed. At this time, the conformal metal sheet needs to be pulled out, so that a hollow wire hole 31 will be generated inside the connecting component 100. The electrical connector 20 is sequentially inserted into the first mounting hole 411, the wire hole 31 and the second mounting hole 412.

[0190] The electrical connector 20 is spaced apart from the support member 10, as can be seen in the relevant description in the aforementioned Embodiment 1.

[0191] The electrical connector 20 is located on the curved outer side of the support member 10, as described in the relevant description in the aforementioned Embodiment 1.

[0192] When the connecting assembly 100 undergoes bending or torsional deformation, the tensile or torsional stress on the inner side (-z) of the bending of the electrical connector 20 is relatively concentrated. In this embodiment, by placing the electrical connector 20 on the outer side of the bending of the support member 10, and with the width of the electrical connector 20 being less than or equal to the width of the support member 10, the support member 10 can act as a stress protector for the electrical connector 20 during bending or torsional deformation. The support member 10, through its high elastic modulus, disperses the concentrated stress generated during bending, preventing breakage of the substrate or copper wires in the electrical connector 20. The support member 10 serves to protect the electrical connector 20; for example, it can function as a reinforcing plate for the electrical connector 20, protecting it from significant bending damage.

[0196] Optionally, the support member 10 may be exposed outside the cover member 30 and may be located on the inside of the bend and / or on the side of the connecting assembly 100 along the width direction.

[0197] Please see Figure 25 This application provides a connection component 100 according to Embodiment 3. The connection component 100 includes a support member 10, an electrical connector 20, and a cover member 30.

[0198] The support member 10 includes a support sheet 10a. The support sheet 10a may include, but is not limited to, a shape memory sheet.

[0199] The shape, material, structure, and position of the support member 10 in this embodiment can be referenced from the shape, material, structure, and position of the corresponding support member 10 in Embodiment 1.

[0200] The shape, material, structure, and position of the electrical connector 20 in this embodiment can be referenced from the shape, material, structure, and position of the corresponding electrical connector 20 in Embodiment 1.

[0201] The shape, material, structure, and position of the covering 30 in this embodiment can be referenced from the shape, material, structure, and position of the corresponding covering 30 in Embodiment 1.

[0202] Electrical connectors 20 include, but are not limited to, flexible circuit boards 23 or insulated conductive wires.

[0203] The orthographic projection area of ​​the electrical connector 20 in the thickness direction Z at least partially overlaps with the orthographic projection area of ​​the support piece 10a in the thickness direction Z, as can be seen in the relevant description in the aforementioned Embodiment 1.

[0204] The electrical connector 20 and the support member 10 are spaced apart or in contact in the thickness direction Z, as can be seen in the relevant description in the aforementioned embodiment 1.

[0205] The covering 30 is disposed on the periphery of the electrical connector 20, as can be found in the relevant description in the aforementioned Embodiment 1.

[0206] The covering 30 surrounds and covers the entire periphery of the support 10, as can be seen in the relevant description in the aforementioned Embodiment 1.

[0207] The support member 10 is hidden within the covering member 30, as can be found in the relevant description in the aforementioned Embodiment 1.

[0208] The connection assembly 100 provided in this application includes a support member 10, an electrical connector 20, and a covering member 30. The support member 10 includes a support sheet 10a. The orthographic projection area of ​​the electrical connector 20 in the thickness direction Z at least partially overlaps with the orthographic projection area of ​​the support sheet 10a in the thickness direction Z. The covering member 30 surrounds the periphery of the electrical connector 20 and covers the entire periphery of the support member 10. The support member 10 is hidden in the covering member 30. The covering member 30 provides a soft covering for the electrical connector 20 and the support member 10, giving the connection assembly 100 a certain elastic deformation capability. The support sheet 10a can protect the electrical connector 20 in the thickness direction Z, thereby reducing the deformation stress on the electrical connector 20 during the elastic deformation of the connection assembly 100, reducing the risk of breakage of the internal wires during the elastic deformation of the connection assembly 100, and improving stability.

[0209] The support member 10 is arc-shaped in the length direction, and the electrical connector 20 is located on the outside of the curve of the support member 10.

[0210] When the connecting assembly 100 undergoes bending or torsional deformation, stress concentration easily forms in the thickness direction Z. The support piece 10a, through its high elastic modulus, disperses the concentrated stress generated during bending of the connecting assembly 100, effectively protecting the electrical connector 20 in the thickness direction Z and preventing breakage of the substrate or copper wires of the electrical connector 20. The support piece 10a also absorbs some of the alternating stress through micro-plastic deformation, delaying substrate fatigue. When the support piece 10a is a shape memory metal, its superelastic effect can offset most of the bending energy, maintaining circuit stability when the connecting assembly 100 is repeatedly bent. In addition, the sheet-like support piece 10a also has good resistance to lateral torsion, reducing torsional deformation damage to the electrical connector 20.

[0211] In this embodiment, the electrical connector 20 is located on the outside of the bent support plate 10a. The support plate 10a can act as a stress protector for the electrical connector 20 during bending or torsional deformation. The support plate 10a, with its high elastic modulus, disperses the concentrated stress generated during bending, preventing breakage of the substrate or copper wires in the electrical connector 20. The support plate 10a protects the electrical connector 20; for example, it can be reused as a reinforcing plate for the electrical connector 20 to protect it and prevent it from being damaged by significant bending.

[0239] In this embodiment, the earphone 200 includes, but is not limited to, clip-on earphones. The first earphone part 210 can also be called a listening ball or a sound-emitting ball. The second earphone part 220 is also called a comfort bean or a battery bean. The connecting component 100 is also called a connecting bridge. The connecting component 100 is a flexible structure connecting the first earphone part 210 and the second earphone part 220. The connecting component 100 is lightweight and ergonomic. The connecting component 100 can be clipped onto the ear bridge. The connecting component 100 includes a shape memory material (support member 10) and soft rubber (covering member 30). The covering member 30 provides cushioning, and the inner layer is embedded with the support member 10 to maintain elastic deformation and fatigue resistance, adapt to different ear shape bending requirements, disperse stress during bending, and extend service life.

[0240] Embodiment 5 of this application provides an earphone device. The earphone device includes an earphone case and earphones 200 as described in any of the foregoing embodiments. The earphones 200 are housed within the earphone case. The number of earphones 200 can be a pair.

[0241] The following example uses earphone 200 as an ear clip-on earphone, connecting component 100 as a connecting bridge, covering component 30 as soft rubber, electrical connector 20 as a flexible circuit board 23, and support component 10 as a memory metal sheet or metal strip.

[0242] This application controls the shape and adjusts the wearing comfort of the earphone 200 by adding a memory metal sheet or metal strip (the aforementioned support member 10) inside the connecting bridge (the aforementioned connecting component 100). Then, the sound ball (the aforementioned first earphone part 210) and the battery bead (the aforementioned second earphone part 220) are connected in the soft rubber (such as the aforementioned covering member 30) by FPC wire (the aforementioned electrical connector 20). Because the wire is a flat FPC and the shaped memory metal is also a metal sheet, the overall shape of the connecting bridge is flat.

[0243] In general, because FPCs are relatively soft and lack surrounding hard adhesive protection, they may break and malfunction due to stretching or torsional deformation of the connecting bridge during use. Furthermore, with the development of clip-on headphones, more and more functions will be added, leading to an increase in the number of wires that need to be routed within the connecting bridge. Therefore, how to accommodate multiple wires within the connecting bridge and reduce the likelihood of these wires breaking and malfunctioning due to stretching or torsional deformation has become a technical problem that needs to be solved.

[0244] This application arranges the shape memory metal sheet (the aforementioned support member 10) and the FPC (the aforementioned electrical connector 20) in the thickness direction Z by superimposing them. First, the FPC can solve the problem of needing to run more wire cores in the connecting bridge (the aforementioned connecting component 100) after the functions are increased. Second, in addition to providing stable clamping force and shaping the product, the shape memory metal sheet can also act as a reinforcing plate for the FPC, providing strength to the FPC body and preventing wire breakage during stretching and twisting.

[0245] The connecting bridge body has a flat cross-sectional shape, but its shape can be adjusted according to the product's shape requirements, such as changing it from a flat shape to a horizontal ellipse. The internal structure of the connecting bridge consists of a soft rubber shell (covering part 30) that completely encloses and secures the memory metal sheet. Then, the FPC is passed through the pre-drilled wire hole 31, which connects to the two ends of the sound tube (first earphone part 210) and the battery bead (second earphone part 220), forming a complete product system. To ensure the ease of assembly during subsequent wiring, the wire hole 31 needs to be 0.1-0.5mm larger than the wire's overall dimensions.

[0246] The connecting bridge is fixed by first molding the shaped memory metal sheet to the two ends of the plastic hard plastic or metal alloy injection molding (first mounting end 41 and second mounting end 42) to form a whole, thus strongly fixing its head and tail. At the same time, the plastic hard plastic or metal alloy is also strongly fixed to the sound ball (first earphone part 210) and the battery bead (second earphone part 220) respectively to prevent the connecting bridge from detaching from the sound ball (first earphone part 210) and the battery bead (second earphone part 220) at its two ends. Then, before injection molding the soft plastic shell, the shaped metal sheet is inserted into the wire hole 31 reserved on both sides of the plastic hard plastic or metal alloy (first mounting end 41 and second mounting end 42), and then the whole assembly is injection molded together with soft plastic.

[0247] After the rubber injection molding is completed, the shape of the connecting bridge is finished. At this time, the conforming metal sheet needs to be pulled out, which will create a hollow wire hole 31 inside the connecting bridge.

[0248] In the case of flat connecting bridges, the internal FPC is more prone to tearing and breakage than the cable core wires during tensile and torsional processes. The shape memory metal sheet, located directly beneath the FPC, acts as a reinforcing plate, indirectly protecting the FPC from significant bending damage. To better protect the FPC, the width of the shape memory metal sheet needs to be greater than the width of the FPC during design. This protects the entire FPC and provides sufficient strength. In addition, the shape memory metal sheet also significantly improves lateral torsional resistance.

[0249] To allow the FPC to successfully pass through the hollow hole of the connector bridge, the FPC design must have one vertical end; it cannot have bends at both ends, otherwise the FPC cannot be threaded through. When functionality increases, multiple lines need to be soldered. The FPC and motherboard can be connected via thermoforming using a round hole soldering method. This allows for soldering multiple pins within the existing width without requiring additional soldering space. During FPC soldering, soldering positioning holes, mark points, or lines are needed to align the FPC solder points with the motherboard pads 235.

[0250] This application allows for the simultaneous soldering of all pins, while also reducing the required internal space, thus minimizing the size of the speaker and battery housing. Furthermore, the use of shape memory metal sheets effectively improves the resistance to torsional damage in the connecting bridge.

[0251] In addition to using round hole soldering, FPCs can also be connected to the ends of balls or beads by arranging two rows of 235 pads side by side or by using ZIF and other methods.

[0252] Although embodiments of this application have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present application. Those skilled in the art can make changes, modifications, substitutions, and variations to the above embodiments within the scope of this application. These improvements and refinements are also considered to be within the scope of protection of this application.
