The support tube has a pre-shaped form, maintains a controllable clamping force and has good skin fit when worn. At least a portion of the outer surface of the support tube is the outer surface of the connection component, that is, the support tube is the outer tube of the connection component. The support tube has a wire hole, and the electrical connector is inserted into the wire hole from the outside.

Technical Field

[0001] This application relates to the field of electronic technology, specifically to a connection component and headphones. Background Technology

[0002] With the widespread use of wearable headphones, the connecting components need to be designed with a small cross-sectional size to adjust the controllable clamping force and improve the wearing stability and comfort of the headphones, since they need to be worn on the ear. Therefore, how to reduce the cross-sectional size of the connecting components while maintaining a controllable clamping force has become a technical problem that needs to be solved. Utility Model Content

[0003] This application provides a connection component and headphones that reduce the cross-sectional dimensions of the connection assembly while maintaining controllable clamping force.

[0004] In a first aspect, this application provides a connection component, including:

[0006] An electrical connector, which is inserted into a wire hole inside the support tube.

[0007] This application provides a connecting component comprising a support tube and an electrical connector. The support tube has a pre-shaped form to facilitate molding into an ergonomic structure, maintaining a controllable clamping force and good skin fit during wear. At least a portion of the outer surface of the support tube is the outer surface of the connecting component, i.e., the support tube is the outer tube of the connecting component. The support tube has a through hole, and the electrical connector is inserted through the through hole from the outside. Since the support tube is the outer tube of the connecting component and the electrical connector is inserted inside the support tube, the cross-sectional size of the connecting component can be smaller, and the support tube allows the connecting component to maintain a controllable clamping force.

Detailed Implementation

[0044] The technical solution of this application will now be clearly and completely described with reference to the accompanying drawings. Obviously, the embodiments provided 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.

[0045] In this application, the reference to "embodiment" means that a specific feature, structure, or characteristic provided in 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. Those skilled in the art will explicitly and implicitly understand that the embodiments provided in this application can be combined with other embodiments.

[0046] 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.

[0047] 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.

[0048] 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.

[0049] Please see Figures 2-5 The connecting component 100 includes a support tube 10 and an electrical connector 20.

[0050] Please see Figure 6 The support tube 10 has a predetermined shape.

[0051] Optionally, the initial shape of the support tube 10 is a predetermined shape in its natural state. This predetermined shape includes, but is not limited to, a straight line, an arc, a bend, a curve, or a spiral. In this embodiment, the support tube 10 is generally in a C-shaped bend as an example.

[0052] Please refer to Figure 6 The support tube 10 has a predetermined shape, for example, generally in a C-shaped bend, so as to be shaped into an ergonomic structure, maintain a controllable clamping force and have good skin fit when worn.

[0053] The support tube 10 has a certain elastic deformation capability. After deformation, the support tube 10 can return to its initial shape, so that the connecting component 100 can maintain its initial shape when not subjected to external force, deform after being subjected to external force, and return to its initial shape after the external force is removed.

[0054] For example, the material of the support tube 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 tube 10 includes, but is not limited to, thermoplastic elastomers; or, the material of the support tube 10 includes, but is not limited to, silicone, rubber, or plastic. The support tube 10 made of the above materials allows the support to return to its initial shape after elastic deformation. The shape memory alloy includes, but is not limited to, at least one of nickel-titanium alloys, copper alloys, or iron alloys. Of course, the support tube 10 can also be a composite tube, meaning the support tube 10 incorporates multiple different materials.

[0055] Optionally, the support tube 10 is a solid tube, which has relatively good waterproof and dustproof sealing properties.

[0056] Please see Figure 2 At least a portion of the surface of the support tube 10 is a surface of the connecting assembly 100. For example, the outer surface of the support tube 10 is the outer surface of the connecting assembly 100. That is, the support tube 10 is the outer tube of the connecting assembly 100. As another example, a portion of the outer surface of the support tube 10 is a portion of the outer surface of the connecting assembly 100, and another portion of the surface of the connecting assembly 100 is the outer surface of other structures.

[0057] 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.

[0058] Please see Figure 3 and Figure 5 The support tube 10 has a wire hole 10a. Furthermore, the wire hole 10a extends along the direction in which the support tube 10 is bent.

[0059] Please see Figure 3 and Figure 5 The electrical connector 20 is inserted into the wire hole 10a inside the support tube 10. The electrical connector 20 is used to realize the transmission of electrical signals, so that the connection assembly 100 not only has a clamping function and good elastic deformation capability, but also has the ability to transmit electrical signals.

[0060] Electrical connector 20 includes, but is not limited to, at least one of a conductor, an insulated conductor, or a PFC (flexible circuit board) for transmitting electrical signals.

[0061] Optionally, the support tube 10 is arc-shaped in the length direction. The support tube 10 is generally a long arc-shaped strip. The support tube 10 extends in an arc shape.

[0062] Please see Figure 5 and Figure 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 tube 10.

[0063] Since the support tube 10 is the outer tube of the connecting assembly 100, and the electrical connector 20 is installed inside the support tube 10, the structure of the connecting assembly 100 is small, so the cross-sectional size of the connecting assembly 100 can be small, and the support tube 10 keeps the connecting assembly 100 under controllable clamping force.

[0064] This application provides a connecting component 100 including a support tube 10 and an electrical connector 20. The support tube 10 has a pre-shaped form to facilitate molding into an ergonomic structure, maintaining a controllable clamping force and good skin fit during wear. At least a portion of the outer surface of the support tube 10 is the outer surface of the connecting component 100, i.e., the support tube 10 is the outer tube of the connecting component 100. The support tube 10 has a wire hole 10a, and the electrical connector 20 is inserted into the wire hole 10a from the outside. Since the support tube 10 is the outer tube of the connecting component 100 and the electrical connector 20 is inserted into the support tube 10, the cross-sectional size of the connecting component 100 can be smaller, and the support tube 10 allows the connecting component 100 to maintain a controllable clamping force.

[0065] In one alternative implementation, please refer to Figure 3 and Figure 5 The cross-sectional dimension of the hole 10a can be slightly larger than the external dimensions of the electrical connector 20. There is a clearance between the hole wall of the support tube 10 and the outer surface of the electrical connector 20 to allow the electrical connector 20 to pass smoothly through the hole 10a into the support tube 10. Furthermore, this application uses a relatively small distance between the outer surface of the electrical connector 20 and the hole wall of the support tube 10, making the cross-sectional dimension of the connecting assembly 100 as small as possible and the radial dimension of the support tube 10 as small as possible. This results in relatively low resistance to deformation of the support tube 10, facilitating the removal or wearing of the headphones by stretching or twisting the connecting assembly 100.

[0066] Optionally, the distance between the outer peripheral surface of the electrical connector 20 and the wall of the wire hole 10a is 0mm to 1.5mm, but is not limited to this data. This ensures that the electrical connector 20 can smoothly pass through the wire hole 10a, guaranteeing the assembleability of subsequent wiring, while also preventing the wire hole 10a from being too large, thus minimizing the cross-sectional dimensions of the connecting assembly 100.

[0067] In one optional embodiment, the support tube 10 includes at least one of shape memory tube, stainless steel tube, elastic metal alloy tube, silicone tube, and plastic tube.

[0068] For example, the support tube 10 includes a shape memory tube, which has a certain rigidity and a certain elastic deformation capability. The shape memory tube can return to its initial shape after deformation, so that the connecting component 100 can maintain its initial shape when not subjected to external force, deform after being subjected to external force, and return to its initial shape after the external force is removed.

[0069] For example, shape memory tubes include, but are not limited to, shape memory polymer tubes or shape memory alloy tubes. Shape memory alloy tubes include, but are not limited to, at least one of nickel-titanium alloy tubes, copper alloy tubes, or iron alloy tubes.

[0070] For example, shape memory polymer tubes include, but are not limited to, polyester TPE elastic tubes or polyurethane (PU) tubes.

[0071] In one alternative embodiment, the electrical connector 20 includes at least one of an insulated wire, an enameled wire, or a flexible circuit board to enable electrical signal transmission.

[0072] For example, when the support tube 10 is a shape memory metal tube, a stainless steel tube, or a flexible metal alloy tube, the conductor of the electrical connector 20 is covered with at least one insulating layer to prevent the conductor from contacting and conducting with the shape memory metal tube. That is, the insulating layer can achieve electrical insulation and avoid the influence of the support tube 10 on the transmission of the electrical connector 20.

[0073] For example, when the support tube 10 is a shape memory polymer tube, or a silicone tube, or a plastic tube, the insulation layer covering the wires of the electrical connector 20 can be appropriately reduced.

[0074] In one optional embodiment, the wall thickness of the support tube 10 is 0.1 mm to 0.8 mm.

[0075] This embodiment achieves a relatively large aperture for the wire-passing hole 10a without increasing the outer diameter of the support tube 10 by making the wall thickness of the support tube 10 thinner, thus facilitating the smooth passage of the electrical connector 20 through the support tube 10. By designing the support tube 10 to have a thinner wall thickness and a relatively small distance between the hole wall of the support tube 10 and the outer peripheral surface of the electrical connector 20, the cross-sectional size of the connecting assembly 100 is relatively small, which facilitates elastic deformation of the connecting assembly 100, allowing the earphone to be worn or removed from the ear.

[0076] In general technology, the wall thickness of the outer pipe of the electrical connector 20 is relatively thick. Under the limitation of the overall outer diameter of the connecting assembly 100, the inner diameter of the outer pipe is small. During the wire threading process of the electrical connector 20, it is necessary to use an auxiliary metal strip. However, this application designs the support tube 10 to have a certain rigidity and a thinner wall thickness, so that the aperture of the support tube 10 is relatively large, so that the electrical connector 20 can pass smoothly through the support tube 10 without the aid of an auxiliary metal strip.

[0077] Further optionally, the wall thickness of the support tube 10 may include, but is not limited to, 0.1 mm, 0.2 mm, 0.3 mm, 0.4 mm, 0.5 mm, 0.6 mm, 0.7 mm, or 0.8 mm. More specifically, the wall thickness of the support tube 10 may be 0.5 mm. When the outer diameter of the electrical connector 20 is approximately 0.9 mm, the inner diameter of the support tube 10 is approximately 1 mm, and the outer diameter of the support tube 10 is approximately 2 mm. The radial dimension of the cross-section of the connecting assembly 100 is close to 2 mm. While maintaining a controllable clamping force and good skin-fitting properties during wear, the connecting assembly 100 also has a relatively small radial dimension, allowing it to bend and deform to put on or remove the headphones.

[0078] Optional, please refer to Figures 7-14 The connecting component 100 also includes a first fastener 41.

[0079] Please see Figure 15 The first fastener 41 is used to connect the support part to the subsequent first earphone part 210.

[0080] The first fastener 41 is connected to the first end of the support tube 10. Optionally, the material of the first fastener 41 may include, but is not limited to, hard plastic or metal alloy. The connection method between the first fastener 41 and the support tube 10 may include, but is not limited to, at least one of the following: snap-fit ​​connection, bonding, welding, etc.

[0081] For example, please see Figure 12 and Figure 13 The first end of the support tube 10 is provided with a first engaging hole 11 or a first engaging groove, and the first fixing member 41 has a first engaging protrusion 411. The first engaging protrusion 411 engages with the first engaging hole 11 or the first engaging groove, so that the first fixing member 41 and the support tube 10 are engaged. Furthermore, the first fixing member 41 and the support tube 10 can also be bonded together with adhesive to improve the connection firmness and sealing between the first fixing member 41 and the support tube 10.

[0082] When the first end of the support tube 10 is provided with a first engaging hole 11, this application does not specify the shape of the first engaging hole 11. The first engaging hole 11 may include, but is not limited to, a round hole, a square hole, a triangular hole, an elliptical hole, or an irregular hole.

[0083] When the first end of the support tube 10 is provided with a first engaging groove, this application does not specify the shape of the first engaging groove. The first engaging groove may include, but is not limited to, a circular groove, a square groove, a triangular groove, an elliptical groove, or an irregular groove.

[0084] Please see Figure 10 and Figure 14 The first fastener 41 has a first mounting hole 412.

[0085] The first mounting hole 412 communicates with the first end of the wire hole 10a. The electrical connector 20 passes through the first mounting hole 412 and the wire hole 10a. Specifically, both the first mounting hole 412 and the wire hole 10a communicate with the inner cavity of the first earphone part 210, so that the first end of the electrical connector 20 can be disposed in the inner cavity of the first earphone part 210 and electrically connected to the electronic devices inside the first earphone part 210.

[0086] For the first alternative implementation, please refer to Figures 11-14 One end of the first fixing member 41 is disposed in the wire hole 10a. Specifically, one end of the first fixing member 41 is disposed in the wire hole 10a of the support tube 10, and the other end of the first fixing member 41 is fixedly connected to the first earphone part 210.

[0087] In this embodiment, the electrical connector 20 can pass through the first mounting hole 412, and one end of the first fixing member 41 is located in the wire hole 10a. Thus, the size of the wire hole 10a is slightly larger than one side of the electrical connector 20, so that the electrical connector 20 can pass smoothly through the support tube 10.

[0088] For example, the electrical connector 20 is a multi-bundle insulated wire. The outer diameter of the electrical connector 20 is approximately 1 mm, and the outer diameter of the support tube 10 is approximately 3.3 mm. The wall thickness of the support tube 10 is 0.5 mm, and the diameter of the wire-passing hole 10a in the support tube 10 is close to 2.3 mm. Thus, the distance between the wall of the wire-passing hole 10a in the support tube 10 and the outer surface of the electrical connector 20 is close to 1.3 mm, making the diameter of the support tube 10 relatively large. This allows the electrical connector 20 to pass smoothly through the support tube 10 without the aid of an auxiliary metal strip.

[0089] For the second alternative implementation, please refer to... Figures 7-10 The first end of the support tube 10 is located in the first mounting hole 412 of the first fixing member 41. Specifically, one end of the first fixing member 41 is located in the wire hole 10a of the support tube 10, and the other end of the first fixing member 41 is fixedly connected to the first earphone part 210.

[0090] In this embodiment, the first end of the support tube 10 is located in the first mounting hole 412 of the first fixing member 41, so that the outer diameter of the support tube 10 can be designed to be relatively small.

[0091] For example, the electrical connector 20 consists of multiple bundles of insulated wires. The outer diameter of the electrical connector 20 is approximately 1 mm, and the outer diameter of the support tube 10 is approximately 2.1 mm. The wall thickness of the support tube 10 is 0.5 mm, and the diameter of the through hole 10a is close to 1.1 mm. Thus, the distance between the wall of the through hole 10a and the outer surface of the electrical connector 20 is close to 0.1 mm. The relatively small outer diameter of the support tube 10 gives it good elastic deformation capability, which is beneficial for adjusting the clamping force.

[0092] Optional, please refer to Figures 7-14 The connecting component 100 also includes a second fastener 42.

[0093] Please see Figure 15 The second fastener 42 is used to connect the support part to the subsequent second earphone part 220.

[0094] The second fastener 42 is connected to the second end of the support tube 10. Optionally, the material of the second fastener 42 may include, but is not limited to, hard plastic or metal alloy. The connection method between the second fastener 42 and the support tube 10 may include, but is not limited to, at least one of the following: snap-fit ​​connection, bonding, welding, etc.

[0095] For example, please see Figure 12 and Figure 13 The second end of the support tube 10 is provided with a second engaging hole 12 or a second engaging groove, and the second fixing member 42 has a second engaging protrusion 421. The second engaging protrusion 421 engages with the second engaging hole 12 or the second engaging groove, so that the second fixing member 42 and the support tube 10 are engaged. Furthermore, the second fixing member 42 and the support tube 10 can also be bonded together with adhesive to improve the connection firmness and sealing between the second fixing member 42 and the support tube 10.

[0096] When the second end of the support tube 10 is provided with a second engaging hole 12, this application does not specify the shape of the second engaging hole 12. The second engaging hole 12 may include, but is not limited to, a round hole, a square hole, a triangular hole, an elliptical hole, or an irregular hole.

[0097] When the second end of the support tube 10 is provided with a second engaging groove, this application does not specify the shape of the second engaging groove, and the second engaging groove includes, but is not limited to, a circular groove, a square groove, a triangular groove, an elliptical groove, or an irregular groove.

[0098] Please see Figure 10 and Figure 14 The second fastener 42 has a second mounting hole 422.

[0099] The second mounting hole 422 communicates with the second end of the wire hole 10a. The electrical connector 20 passes through the second mounting hole 422 and the wire hole 10a. Specifically, both the second mounting hole 422 and the wire hole 10a communicate with the inner cavity of the second earphone part 220, so that the second end of the electrical connector 20 can be disposed in the inner cavity of the second earphone part 220 and electrically connected to the electronic devices inside the second earphone part 220.

[0100] Furthermore, the electrical connector 20 enters the inner cavity of the second earphone part 220 from the inner cavity of the first earphone part 210, passing sequentially through the first mounting hole 412, the wire hole 10a, and the second mounting hole 422. Optionally, the electrical connector 20 can be electrically connected to electronic devices in the first earphone part 210 and electronic devices in the second earphone part 220.

[0101] For the first alternative implementation, please refer to Figures 11-14 One end of the second fixing member 42 is disposed in the wire hole 10a. Specifically, one end of the second fixing member 42 is disposed in the wire hole 10a of the support tube 10, and the other end of the second fixing member 42 is fixedly connected to the second earphone part 220.

[0102] In this embodiment, the electrical connector 20 can pass through the second mounting hole 422, and one end of the second fixing member 42 is located in the wire hole 10a. Thus, the size of the wire hole 10a is slightly larger than one side of the electrical connector 20, so that the electrical connector 20 can pass smoothly through the support tube 10.

[0103] For example, the electrical connector 20 is a multi-bundle insulated wire. The outer diameter of the electrical connector 20 is approximately 1 mm, and the outer diameter of the support tube 10 is approximately 3.3 mm. The wall thickness of the support tube 10 is 0.5 mm, and the diameter of the wire-passing hole 10a in the support tube 10 is close to 2.3 mm. Thus, the distance between the wall of the wire-passing hole 10a in the support tube 10 and the outer surface of the electrical connector 20 is close to 1.3 mm, making the diameter of the support tube 10 relatively large. This allows the electrical connector 20 to pass smoothly through the support tube 10 without the aid of an auxiliary metal strip.

[0104] For the second alternative implementation, please refer to... Figures 7-10 The second end of the support tube 10 is located in the second mounting hole 422 of the second fixing member 42. Specifically, one end of the second fixing member 42 is located in the wire hole 10a of the support tube 10, and the other end of the second fixing member 42 is fixedly connected to the second earphone part 220.

[0105] In this embodiment, the second end of the support tube 10 is located in the second mounting hole 422 of the second fixing member 42, so that the outer diameter of the support tube 10 can be designed to be relatively small.

[0106] For example, the electrical connector 20 consists of multiple bundles of insulated wires. The outer diameter of the electrical connector 20 is approximately 1 mm, and the outer diameter of the support tube 10 is approximately 2.1 mm. The wall thickness of the support tube 10 is 0.5 mm, and the diameter of the through hole 10a is close to 1.1 mm. Thus, the distance between the wall of the through hole 10a and the outer surface of the electrical connector 20 is close to 0.1 mm. The relatively small outer diameter of the support tube 10 gives it good elastic deformation capability, which is beneficial for adjusting the clamping force.

[0107] Optionally, the support tube 10 includes a metal tube. By making the support tube 10 a metal tube, compared to a plastic tube, the surface of the metal tube can have more surface treatment options, so that the surface of the connecting assembly 100 has different visual textures or tactile sensations.

[0108] In one alternative implementation, please refer to Figure 16 At least a portion of the surface of the support tube 10 includes a matte surface 13a.

[0109] For example, a portion or all of the surface of the support tube 10 includes a matte surface 13a. Alternatively, the outer surface layer of the support tube 10 includes a matte layer. Furthermore, this matte surface 13a is also a portion of the outer surface of the connecting component 100. The tiny frosted particles formed on the matte metal surface increase friction, preventing the earphones from slipping off during exercise, especially suitable for a secure fit in sweaty environments; the matte finish on the outer surface of the connecting component 100 reduces the coldness and harshness of the metal; the matte surface can conceal minor wear and tear from daily use, maintaining a premium look; and the matte surface 13a reduces glare and eliminates dazzling spots from specular reflections, improving visual comfort during wear.

[0110] For example, please see Figure 17 The support tube 10 has a partial or complete surface including a micro-pit structure 13b. For example, a uniform micro-pit structure 13b is formed by impacting the metal surface with high-speed diamond abrasive to create a matte surface 13a. In other embodiments, the matte surface 13a or a matte layer can also be formed by immersing the metal in a high-concentration acid / alkali solution to corrode the surface. In other embodiments, an electrolyte is applied to cause oxidation-reduction on the metal tube surface to form a matte surface 13a or a matte layer.

[0111] For example, please see Figure 18The support tube 10 has a partial or complete surface including an electroplated layer 13c. Alternatively, the outer surface layer of the support tube 10 includes the electroplated layer 13c. Furthermore, this electroplated layer 13c is also a partial outer surface of the connecting assembly 100. The electroplated layer 13c isolates the metal substrate (such as stainless steel or aluminum alloy) from sweat and moisture, preventing oxidation and rust, and extending its service life. Chlorides in sweat easily corrode the substrate; the electroplated layer 13c (such as nickel or gold) forms a dense barrier, ensuring long-term stability. Furthermore, the electroplated layer 13c can be customized in color (such as rose gold or gunmetal gray) to enhance product recognition and color saturation.

[0112] For example, please see Figure 19 The support tube 10 has a partial or complete surface covered by a coating film 13d. Alternatively, the outer surface layer of the support tube 10 includes the coating film 13d. Further, the coating film 13d is also a partial outer surface of the connecting assembly 100. The coating film 13d includes, but is not limited to, a nano-coating. The nano-coating enhances substrate adhesion, inhibits microcrack propagation, and improves the bending strength and fatigue fracture resistance of the metal bridge. Furthermore, the nano-coating forms a 150° superhydrophobic angle, blocking the adhesion of sweat / condensation and preventing oxidation failure.

[0113] For example, please see Figure 20 The support tube 10 has a partial or complete surface including a polished surface 13e. Alternatively, the outer surface layer of the support tube 10 includes a polished surface 13e. Further, this polished surface 13e is also a partial outer surface of the connecting assembly 100. The polished surface 13e includes, but is not limited to, mechanical polishing, using a wool wheel or sandpaper to gradually reduce roughness to a roughness less than or equal to 0.2–0.4 μm. The polished surface 13e also includes, but is not limited to, electrolytic polishing, using electricity to dissolve microscopic protrusions on the surface, achieving a mirror effect, and reducing the roughness to a roughness less than or equal to 0.2–0.4 μm. Polishing forms a dense surface layer, effectively blocking chlorides in sweat from corroding the metal substrate and slowing down the oxidation and rusting process. Simultaneously, a smooth surface reduces liquid retention, lowering the risk of electrochemical corrosion in humid environments; polishing reduces the surface roughness of the metal to the nanometer level (referencing fluid polishing technology), reducing wear between moving parts; it also eliminates surface microcracks and scratches, improving the bending resistance of the metal bridge.

[0114] For example, please see Figure 21The support tube 10 has a partial or complete surface including a textured surface 13f. Alternatively, the outer surface layer of the support tube 10 includes a textured surface 13f. Furthermore, this textured surface 13f is also a partial outer surface of the connecting component 100. The textured surface 13f can be formed, but is not limited to, sandblasting, frosting, or wood grain transfer. Textures (such as regular brushed lines or ripples) improve bending resistance and reduce the risk of metal fatigue fracture caused by frequent opening and closing by reshaping the stress distribution on the metal surface. The steel mesh texture structure can further resist external impacts and protect the internal sound unit; frosted textures (such as sandblasting) increase the surface friction coefficient, preventing the headphones from slipping off when worn; and simultaneously reducing fingerprints and sweat adhesion.

[0115] For example, please see Figure 22 The support tube 10 has a partial or complete surface including a textured surface 13h. Alternatively, the outer surface layer of the support tube 10 includes the textured surface 13h. Furthermore, the textured surface 13h is also a partial outer surface of the connecting component 100. The textured surface 13h can be formed, including but not limited to embossing, drawing, or laser engraving. By providing the textured surface 13h, brand recognition can be enhanced, a soft touch can be provided, and the coldness of metal can be eliminated. Etching a custom logo or geometric pattern can further enhance brand recognition.

[0116] Optional, please refer to Figure 23 The connection assembly 100 further includes a buffer 30. The buffer 30 is disposed between the electrical connector 20 and the inner wall of the support tube 10. The buffer 30 is used to reduce the rigid contact between the electrical connector 20 and the support tube 10, prevent mechanical damage, absorb vibration, and provide insulation protection, thereby avoiding damage or breakage to the substrate or wiring of the electrical connector 20.

[0117] Optionally, the buffer 30 may be disposed on the inner wall of the support tube 10. For example, the buffer 30 may be at least one of the following: tubular, strip-shaped, ring-shaped, arc-shaped, or dot-shaped.

[0118] The buffer 30 may abut against the outer peripheral surface of the electrical connector 20 or may not contact the electrical connector 20. That is, the buffer 30 and the electrical connector 20 are spaced apart, leaving a relatively large space for the electrical connector 20 to pass through the support tube 10, so that the electrical connector 20 can pass through the support tube 10 smoothly.

[0119] Optionally, the cushioning element 30 may include, but is not limited to, at least one of silicone, foam, and rubber.

[0120] Furthermore, the buffer 30 includes, but is not limited to, at least one of silicone buffer, foam buffer, hard rubber buffer, soft rubber buffer, thermoplastic polyurethane buffer, semi-hard rubber buffer, and composite rubber buffer of hard and soft rubber.

[0121] Soft rubber is made from rubber with low sulfur content through vulcanization, and has good elasticity and softness. Its Shore hardness is usually below 30, and the hardness can be further reduced by adding softeners (such as mineral oil).

[0122] Hard rubber, with its higher degree of vulcanization (higher sulfur content), exhibits a more stable three-dimensional structure and possesses better corrosion resistance, aging resistance, and strong adhesion to metals. For example, high-styrene rubber (styrene-butadiene rubber series) exhibits stronger rigidity due to its high styrene content and is often referred to as "hard rubber."

[0123] Semi-hard rubber has a hardness between that of soft and hard rubber, ranging from 30 to 50.

[0124] Alternatively, the buffer 30 may extend in the same direction as the length of the support tube 10. For example, the buffer 30 may be tubular or strip-shaped.

[0125] In this embodiment, the extension direction of the buffer 30 is the same as the length direction of the support tube 10, so as to avoid the buffer 30 forming a pit in the length direction of the support tube 10. This pit may form an obstacle during the process of the electrical connector 20 passing through the support tube 10, thereby making the process of the electrical connector 20 passing through the support tube 10 smoother and preventing hard contact with the support tube 10, which would cause damage or breakage to the substrate or wiring of the electrical connector 20.

[0126] Optional, please refer to Figure 24a The connecting assembly 100 further includes a positioning member 50. The positioning member 50 is disposed within the wire hole 10a. The positioning member 50 abuts against the wall of the wire hole 10a and the electrical connector 20. The positioning member 50 is used to position the electrical connector 20 within the wire hole 10a, so that the electrical connector 20 is relatively fixed within the support tube 10 and does not move around.

[0127] Please refer to Figure 24a The positioning element 50 may be disposed on the outer peripheral surface of the electrical connector 20. The positioning element 50 may be, but is not limited to, a deformable material, a deformable structure, or a compressible material.

[0128] The positioning member 50 enters the wire hole 10a together with the electrical connector 20 and abuts against the wall of the wire hole 10a, so that the electrical connector 20 is relatively fixed in the wire hole 10a, and avoids the electrical connector 20 from shaking or colliding in the wire hole 10a due to the change of the headphone's posture.

[0129] Optionally, the positioning element 50 may be, but is not limited to, at least one of silicone, foam, and rubber.

[0130] Furthermore, the positioning component 50 includes, but is not limited to, at least one of silicone cushioning, foam cushioning, hard rubber cushioning, soft rubber cushioning, thermoplastic polyurethane cushioning, semi-hard rubber cushioning, and composite rubber cushioning of hard and soft rubber.

[0131] The shape of the positioning element 50 includes, but is not limited to, tubular, strip-shaped, ring-shaped, arc-shaped, or dot-shaped.

[0132] Furthermore, there are multiple positioning elements 50, which are respectively located on different sides of the electrical connector 20. This ensures that the peripheral side of the electrical connector 20 is spaced apart from the wall of the wire hole 10a, preventing the electrical connector 20 from making hard contact with the wall of the support tube 10 and keeping the electrical connector 20 relatively fixed within the wire hole 10a.

[0133] For example, please see Figure 24b The positioning member 50 includes a fixed end 51 and a free end 52. The fixed end 51 is fixedly connected to the electrical connector 20. The direction of the line connecting the fixed end 51 and the free end 52 forms an acute angle with the length direction of the electrical connector 20. The positioning member 50 is inclined relative to the electrical connector 20. A deformation space is formed between the free end 52 and the electrical connector 20, meaning that the free end 52 can approach the electrical connector 20 under external force.

[0134] Further, please refer to Figure 24b In the cross-section along the length direction, the fixed end 51 and the free end 52 are along the through-hole direction of the electrical connector 20 ( Figure 24b The arrows in the diagram are arranged sequentially. That is, for the same positioning element 50, the fixed end 51 is closer to the outlet of the support tube 10, and the free end 52 is closer to the inlet of the support tube 10.

[0135] During the process of the electrical connector 20 passing through the support tube 10, the free end 52 of the positioning member 50 abuts against the inner wall of the support tube 10 and is either squeezed or not squeezed within the support tube 10, causing the free end 52 to move closer to the electrical connector 20 while abutting against the inner wall of the support tube 10.

[0136] In the cross-section along the width direction, the positioning element 50 may be in the shape of a ring, or multiple positioning elements 50 may be arranged around the periphery of the electrical connector 20. Each positioning element 50 may be in the shape of a strip or a sheet to reduce the frictional resistance between the positioning element 50 and the inner wall of the support tube 10.

[0137] Alternatively, the thickness of the fixed end 51 may be greater than the thickness of the free end 52. The relatively larger thickness of the fixed end 51 increases the firmness of the connection between the fixed end 51 and the electrical connector 20, while the relatively smaller thickness of the free end 52 increases its flexibility, making it easier for the free end 52 to be squeezed and deformed under the action of the support tube 10.

[0138] The positioning element 50 and the buffer element 30 can be selected to be provided or both can be provided simultaneously.

[0139] Optionally, the positioning element 50 can also reduce the rigid contact between the electrical connector 20 and the support tube 10, prevent mechanical damage, absorb vibration, and provide insulation protection, thereby preventing damage or breakage to the substrate or wiring of the electrical connector 20. That is, in the embodiment where the positioning element 50 is provided on the outer periphery of the electrical connector 20, the support tube 10 may not be provided with the buffer element 30.

[0140] Optional, please refer to Figure 25a and Figure 25b The connecting assembly 100 also includes a soft rubber layer 60. The support tube 10 is a curved tube. The soft rubber layer 60 is disposed on the inner side of the curve of the support tube 10.

[0141] Since the surface of the support tube 10 is hard and the temperature is low, a soft rubber layer 60 (soft rubber pad) is provided on the inner curved side of the support tube 10 where it contacts the ear to increase the fit and temperature comfort of the ear.

[0142] The material of the soft rubber layer 60 includes, but is not limited to, silicone, soft rubber, or thermoplastic polyurethane.

[0143] Please see Figure 25b The dimension of the soft rubber layer 60 along the length direction can be smaller than the length of the support tube 10 along the length direction.

[0144] Optional, please refer to Figure 25c The inner side of the bend of the support tube 10 is provided with a corrugated portion 14. The surface of the corrugated portion 14 is an uneven corrugated surface. The corrugated portion 14 is formed by forming a corrugated surface on the inner side of the bend of the support tube 10. When the connecting assembly 100 undergoes elastic deformation, the bending angle of the inner side -z of the bend of the support tube 10 gradually increases or decreases, and the deformation stress of the inner side -z of the bend of the support tube 10 is concentrated. By providing a corrugated portion 14 on the inner side of the bend of the support tube 10, a portion of the deformation stress is absorbed, thereby improving the fatigue fracture resistance of the support tube 10. Figure 25c The soft rubber layer 60 may not be provided in the middle.

[0145] Further, please refer to Figure 25cA soft rubber layer 60 can be provided on the outer surface of the corrugated portion 14. On the one hand, this avoids the uneven surface of the corrugated portion 14 from directly contacting the ear and causing discomfort to the ear; on the other hand, the combination of the uneven surface of the corrugated portion 14 and the soft rubber layer 60 can further increase the bonding strength between the corrugated portion 14 and the soft rubber layer 60 compared to a smooth surface.

[0146] Optional, please refer to Figure 25d The support tube 10 has a thinning portion 15 on its inner curved side. The thickness of the thinning portion 15 is less than the thickness of other areas of the support tube 10. The thinning portion 15 reduces or creates a relatively thin thickness on the inner curved side of the support tube 10. When the connecting assembly 100 undergoes elastic deformation, the bending angle of the inner curved side -z of the support tube 10 gradually increases or decreases, and the deformation stress of the inner curved side -z of the support tube 10 concentrates. By providing the thinning portion 15 on the inner curved side of the support tube 10, deformation is more likely to occur, thereby absorbing some of the deformation stress and improving the fatigue fracture resistance of the support tube 10. Figure 25d The soft rubber layer 60 may not be provided in the middle.

[0147] Further, please refer to Figure 25d A soft rubber layer 60 can be provided on the outer surface of the thinned portion 15. On the one hand, this avoids the surface of the thinned portion 15 from directly contacting the ear; on the other hand, the soft rubber layer 60 compensates for the thickness of the area where the thinned portion 15 is located, making the outer diameter of the connecting component relatively uniform, reducing the gap between the connecting component and the ear, increasing the contact area with the ear, and increasing the stability of the earphone.

[0148] Furthermore, the outer diameter of the support tube 10 can decrease and then increase from one end to the other, with the outer diameter being the smallest in the middle of the support tube 10, so that it is easier to generate tensile or torsional deformation.

[0149] Please see Figures 26-28 Embodiment 3 of this application provides an earphone 200. 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.

[0150] Please see Figure 26 The earphone 200 includes a first earphone portion 210 and a connection component 100 as described in any of the aforementioned embodiments. The first earphone portion 210 is fixed to one end of the connection component 100. Optionally, the first earphone portion 210 may be fixedly connected to the aforementioned first fixing member 41.

[0151] In one alternative implementation, please refer to Figure 26The first earphone unit 210 includes a sound output component 211. The sound output component 211 is electrically connected to one end of the electrical connector 20. The sound output component 211 includes, but is not limited to, a sound-generating unit, etc. Furthermore, the outer shell of the first earphone unit 210 is also provided with a tuning hole, etc., to achieve directional sound entering the ear and reduce sound leakage. The earphone 200 in this embodiment includes, but is not limited to, clip-on earphones, TWS (true wireless stereo) earphones, ear-hook earphones, behind-the-ear earphones, etc.

[0152] For another alternative implementation, please refer to Figure 27 The earphone 200 includes a second earphone portion 220. The second earphone portion 220 is fixed to the other end of the connecting assembly 100. The aforementioned first fixing member 41 is fixedly connected to the first earphone portion 210. The first earphone portion 210 and the second earphone portion 220 are respectively electrically connected to both ends of the electrical connector 20. The aforementioned second fixing member 42 is fixedly connected to the second earphone portion 220. The second earphone portion 220 includes a power supply component 221. The power supply component 221 is electrically connected to the other end of the electrical connector 20. The power supply component 221 includes a battery, etc. The second earphone portion 220 may also include, but is not limited to, a Bluetooth chip and a sensor, etc. The earphone 200 in this embodiment includes, but is not limited to, clip-on earphones, TWS (True Wireless Stereo) earphones, ear-hook earphones, and behind-the-ear earphones, etc.

[0153] Optional, please refer to Figure 28 The earphone 200 further includes a first earphone portion 210 and a second earphone portion 220. The second earphone portion 220 is fixed to the other end of the connecting assembly 100. The aforementioned first fixing member 41 is fixedly connected to the first earphone portion 210. The first earphone portion 210 and the second earphone portion 220 are respectively electrically connected to both ends of the electrical connector 20. The aforementioned second fixing member 42 is fixedly connected to the second earphone portion 220.

[0154] The first earphone unit 210 includes a sound output component 211. The sound output component 211 is electrically connected to one end of the electrical connector 20. The sound output component 211 includes, but is not limited to, a sound-generating unit, etc. Furthermore, the outer shell of the first earphone unit 210 is also provided with tuning holes, etc., to achieve directional sound entering the ear and reduce sound leakage.

[0155] The second earphone unit 220 includes a power supply unit 221. The power supply unit 221 is electrically connected to one end of the electrical connector 20. The power supply unit 221 includes a battery, etc. The second earphone unit 220 may also include, but is not limited to, a Bluetooth chip and sensors, etc.

[0156] 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 tube 10) and soft rubber (buffer 30). The buffer 30 provides cushioning, and the inner layer is embedded in the support tube 10 to maintain elastic deformation and fatigue resistance, adapt to different ear shape bending requirements, disperse stress during bending, and extend service life.

[0157] Embodiment 4 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.

[0158] Optionally, taking the connecting component 100 as a connecting bridge as an example, the connecting bridge is a rigid or elastic component between the earphone body and the wearing structure, usually made of lightweight materials (such as titanium alloy or polymer materials) to ensure a stable fit to the shape of the ear. The first earphone part 210 is a sound-emitting ball, which is the acoustic module of the open-back earphone. This module usually contains acoustic components such as speakers, and is close to the human ear canal when worn to achieve sound output. The second earphone part 220 is a battery holder, which is the electrical module of the open-back earphone. This module usually contains components such as batteries, circuit boards, and charging modules. The support tube 10 is a shape memory metal tube.

[0159] The shape of the connecting bridge is maintained by utilizing the properties of the shape memory metal tube, thereby achieving comfortable wearing. In addition, a hollow channel (wire hole 10a) is formed in the shape memory metal tube, reserving space for the core wire (electrical connector 20). The core wire (electrical connector 20) is inserted to connect the components inside the sound tube (first earphone part 210) and the battery bead (second earphone part 220).

[0160] In general technology, the surface treatment methods for soft rubber outer sheaths are relatively limited. Besides spraying, there aren't many surface effects that can be achieved. Furthermore, under tensile stress, the connecting bridge experiences uneven stress, affecting the overall bending lifespan of the product. Because the radial dimension of soft rubber is relatively large in cross-section, if the outer sheath of the connecting component 100 has poor elastic deformation capability, it will result in significant pressure on the ear during wear, causing pain. Additionally, users typically need to pry the speaker and battery bead outwards, a distance greater than the thickness of the ear. If the connecting bridge is stiff, this will further complicate the wearing experience.

[0161] Based on the above issues, the earphone provided in this application includes a connecting component 100 (connecting bridge), which includes a shape memory metal tube and an electrical connector 20 disposed within the shape memory metal tube. The processing procedure for the shape memory metal tube is relatively simple; it can be made into a strip tube by extrusion or pressing, and then cut to the required length according to the connecting bridge and shaped into the required form. The two ends of the shape memory metal tube are pre-processed with fixing structures, which include, but are not limited to, circular holes, snap-fit ​​holes, and other structural forms.

[0162] The clamping force of the connecting component 100 (connecting bridge) provided in this application is related to the shape and diameter of the memory metal tube. Compared with conventional solutions, the connecting component 100 provided in this application saves the space occupied by the soft tubing. Therefore, the diameter of the memory metal tube can be significantly reduced based on the diameter of the internal core wire (electrical connector 20), thereby reducing the clamping force of the connecting bridge and providing greater flexibility for adjusting the product's human-machine parameters. There are two types of fastener assembly methods: internal fastener insertion and external fastener insertion. The diameter of the memory metal tube in the external fastener insertion type can be made smaller than that in the internal fastener insertion type, which is more conducive to the adjustment of the clamping force by the human-machine interface.

[0163] Furthermore, the surface of shape memory metal tubes can undergo more surface treatments, such as sandblasting, electroplating, wire drawing, and polishing, which are processes that cannot be achieved on soft rubber.

[0164] This application provides a novel connection bridge solution for OWS headphones. This solution reduces the size of the connection bridge, resulting in a more refined product appearance. The connection bridge offers diverse surface treatments, better meeting the aesthetic requirements of the design. The memory metal tube provided in this application has a hollow space (wire hole 10a) in the middle for inserting the core wire (electrical connector 20). This maximizes space utilization, reduces the overall size of the connection bridge while maintaining the controllable clamping force of the memory metal wire. Furthermore, the diverse surface treatments of the memory metal material can meet various product aesthetic requirements.

[0165] The shape memory metal tube provided in this application is not limited by material; it can be nickel-titanium alloy, stainless steel, or even replaced by silicone tube and plastic tube, etc. The tube cross-section in this application includes any hollow tube shape such as round tube, runway round flat tube, rectangular tube, square tube, etc. The core wire (electrical connector 20) provided in this application includes enameled wire and flexible circuit board, etc., which can realize the conduction of electrical signals.

[0166] 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 this application. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of this application, and such improvements and refinements are also considered to be within the protection scope of this application.
