In related technologies, the two ends of the flexible bridge are connected to the two earpieces, and the flexible bridge needs to be repeatedly bent and adjusted to clamp the user's ear. The connection between the flexible bridge and the earpieces is prone to stretching, contraction, and other deformations, which can lead to loosening or even connection failure. Utility Model Content

[0004] This application provides an ear clip-on earphone that can solve the problem of insufficient connection strength between the connecting bridge and the earphone body in the prior art.

[0005] In a first aspect, embodiments of this application provide an ear clip-on earphone, including two housing portions and a connecting bridge. The connecting bridge includes a shape memory alloy wire. The two housing portions are disposed corresponding to the opposite ends of the shape memory alloy wire, so that the two housing portions can clamp the user's auricle under the clamping force provided by the shape memory alloy wire. The connecting bridge further includes at least one first connector. At least one housing portion is mounted to the end of the shape memory alloy wire through a first connector, and the first connector is integrally disposed with the shape memory alloy wire.

[0006] In some embodiments, the shape memory wire includes a main deformation segment and an embedded segment connected to the main deformation segment, wherein the first connector covers the embedded segment.

[0007] In some embodiments, the length of the embedded segment is L, where 3mm ≤ L ≤ 4mm.

[0008] In some embodiments, the outer peripheral wall of the embedded segment has at least one protrusion, which is used to increase the contact area between the embedded segment and the first connector; or, the embedded segment has a multi-segment bent structure.

[0009] In some embodiments, the first connector includes: a first connector integrally disposed with the shape memory alloy wire; and a second connector protruding from the first connector and integrally disposed with the first connector, the second connector being detachably mounted on the housing portion, and the surface of the first connector being in contact with the surface of the housing portion.

[0010] In some embodiments, the angle between the central axis of the end of the shape memory alloy wire and the central axis of the second connector is α, where 60°≤α≤90°.

[0011] In some embodiments, the housing portion includes: a housing having a first mounting hole for a second connector to pass through, a second mounting hole being provided in the portion of the second connector passing through the first mounting hole and located within the internal space of the housing; the second mounting hole extending through the second connector in a direction perpendicular to the extending direction of the second connector; and a limiting pin disposed within the internal space of the housing, the limiting pin passing through the second mounting hole and abutting against the housing.

[0012] In some embodiments, there are two first connectors; one of the first connectors is integrally disposed at one end of the shape memory alloy wire and connected to one of the housing parts; the other first connector is integrally disposed at the other end of the shape memory alloy wire and connected to the other housing part.

[0013] In some embodiments, the clip-on headphones further include: a speaker assembly mounted on one of the housing portions; a power supply assembly mounted on the other housing portion; and a connecting wire, each of the first connectors passing through a wire hole, with both ends of the connecting wire passing through the wire holes of the two first connectors respectively, so that the connecting wire electrically connects the speaker assembly and the power supply assembly.

The shape memory alloy wire has good elasticity and can provide a strong clamping force for the two housing parts so that the housing parts can be worn on the user's ear.

[0016] The connecting bridge also includes at least one first connector for connecting the shape memory alloy wire and one of the housing parts. Since the first connector and the shape memory alloy wire are integrated, the connection strength and tensile strength of the first connector and the shape memory alloy wire are improved while reducing other fixing structures, thus enhancing the durability of the ear clip headphones. It also ensures the fit between the first connector and the shape memory alloy wire, effectively reducing the installation steps and assembly errors in the assembly process, thereby improving the overall quality of the ear clip headphones.

[0030] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0031] Clip-on earphones feature an open design, eliminating the need for in-ear wearing. Compared to in-ear earphones, the structure of clip-on earphones reduces the risk of developing otitis externa due to prolonged wear, thus leading to their increasingly widespread use.

[0032] Clip-on headphones typically consist of a flexible bridge and two earpieces, with one earpiece mounted at each end of the bridge, forming a structure that clamps onto the user's ear. In related technologies, the two ends of the flexible bridge are connected to the two earpieces, and the flexible bridge needs to be repeatedly bent and adjusted to clamp the user's ear. The connection between the flexible bridge and the earpieces is prone to stretching, contraction, and other deformations, which can lead to loosening or even connection failure.

[0033] Please refer to Figures 1 to 2 To solve the above-mentioned technical problems, this application proposes an ear clip-on earphone 100, which includes two housing parts 1 and a connecting bridge 2. The connecting bridge 2 includes a shape memory alloy wire 21. The two housing parts 1 are disposed at opposite ends of the shape memory alloy wire 21 so that the two housing parts 1 can clamp the user's auricle under the clamping force provided by the shape memory alloy wire 21. The connecting bridge 2 also includes at least one first connector 22. At least one housing part 1 is installed on the end of the shape memory alloy wire 21 through a first connector 22, and the first connector 22 is integrally disposed with the shape memory alloy wire 21.

[0034] In this application, the connecting bridge 2 connects two housing parts 1. The connecting bridge 2 includes a shape memory alloy wire 21. The shape memory alloy wire 21 has good elasticity and can quickly return to its original shape after being stretched, thereby providing a strong clamping force for the two housing parts 1, so that the housing parts 1 can be stably worn on the user's ear. The material of the shape memory alloy wire 21 can be titanium wire, nickel-titanium alloy wire, copper-zinc alloy wire, copper-aluminum-nickel alloy wire, copper-molybdenum-nickel alloy wire, or copper-gold-zinc alloy wire, etc., as long as it meets the characteristics of shape memory metal material, this application is not limited thereto.

[0035] The connecting bridge 2 also includes at least one first connector 22, which is used to connect the shape memory alloy wire 21 and one of the housing parts 1. Since the first connector 22 and the shape memory alloy wire 21 are integrally set, the stability of the connection between the first connector 22 and the shape memory alloy wire 21 can still be guaranteed even under multiple bending, shaking or twisting conditions. The connection strength between the first connector 22 and the shape memory alloy wire 21 is high, which enhances the durability of the ear clip earphone 100 and ensures the fit between the first connector 22 and the shape memory alloy wire 21. This effectively reduces the installation steps and assembly errors in the assembly process, thereby improving the overall quality of the ear clip earphone 100.

[0036] In actual use, one of the two housing parts 1 is worn inside the user's concha, and the other is fitted to the back of the ear. When the two housing parts 1 are worn on the user's ear, the connecting bridge 2, i.e. the memory alloy wire 21, is in a stretched state and has the elasticity to return to its original state. The elasticity of the memory alloy wire 21 drives the two housing parts 1 to clamp the user's ear. Since the memory alloy wire 21 can withstand large-scale stretching or twisting without plastic deformation, it has high strength and toughness, thereby further improving the durability of the ear clip-on headphones 100.

[0037] In this embodiment, the number of first connectors 22 is at least one. It is understood that when there is only one first connector 22, it connects one end of the shape memory alloy wire 21 to one of the housing parts 1, ensuring the stability of the connection between the shape memory alloy wire 21 and at least one housing part 1, and also improving the durability of the ear-clip earphone 100 to a certain extent. In other embodiments, the number of first connectors 22 also includes two. The two first connectors 22 are respectively connected to both ends of the shape memory alloy wire 21, and the two first connectors 22 can respectively connect to two housing parts 1, ensuring that both ends of the shape memory alloy wire 21 can be more effectively fixed to the housing part 1, thereby further improving the durability of the ear-clip earphone 100.

[0038] It is understood that in some embodiments, the material of the first connector 22 is the same as that of the shape memory alloy wire 21. The first connector 22 and the shape memory alloy wire 21 are manufactured by stamping the shape memory alloy material into one piece. In these embodiments, the shape memory alloy wire 21 of the first connector 22 has high connection strength.

[0039] Please refer to Figure 3In some embodiments, the first connector 22 is made of a different material than the shape memory alloy wire 21. The first connector 22 is made of plastic, while the shape memory alloy wire 21 is made of metal. The first connector 22 and the shape memory alloy wire are integrally molded using an insert injection molding method. Specifically, the shape memory alloy wire 21 includes a main deformation segment 211 and an embedded segment 212 connected to the main deformation segment 211. The first connector 22 covers the embedded segment 212. During the insert injection molding process, the first connector 22 covers the surface of the embedded segment 212 and forms a strong mechanical bond with the embedded segment 212 of the shape memory alloy wire 21. This ensures that the dimensions of the first connector 22 and the embedded segment 212 can fit perfectly, thereby effectively improving the connection strength between the first connector 22 and the shape memory alloy wire 21. This achieves a high-precision fit between the first connector 22 and the embedded segment 212, eliminating the need for secondary processing, simplifying subsequent installation steps, and further simplifying the production process.

[0040] It is understandable that the embedded section 212 and the first connector 22 cooperate to support the main deformation section 211. The main deformation section 211 can be bent and twisted to fit the ears of different users and to wear and remove the ear clip headphones 100, so as to achieve the effect of using the ear clip headphones 100.

[0041] Specifically, please continue to refer to Figure 2 and Figure 3 The length of the embedded segment 212 is L, where 3mm ≤ L ≤ 4mm. It is worth noting that the length of the embedded segment 212, within the range of 3mm to 4mm, provides a sufficiently large contact area, enabling a strong mechanical bond between the first connector 22 and the shape memory alloy wire 21. Furthermore, the embedded segment 212 can evenly distribute stress, reducing stress concentration points and effectively improving the product's durability and fatigue resistance. In addition, the embedded segment 212 within this length range ensures that the size of the first connector 22 is appropriate while maintaining connection strength, without affecting the installation of other components. It can also be used to control the amount of shape memory alloy wire 21 used, reducing material waste.

[0042] Furthermore, to strengthen the connection between the first connector 22 and the shape memory alloy wire 21, in some embodiments, at least one protrusion 212a is formed on the outer peripheral wall of the embedded segment 212. Figure 3 In the middle, the protrusion is used to increase the contact area between the embedded section 212 and the first connector 22. It can be understood that at least one protrusion 212a is used to contact the first connector 22. By increasing the contact area between the two, a more solid mechanical lock is formed. The protrusion 212a can also act as a "barb" to increase the pull-out resistance and effectively reduce the probability that the embedded section 212 will come out of the first connector 22 when subjected to external force.

[0043] In other embodiments, the embedded segment 212 has a multi-segment bending structure. It is understood that the multi-segment bending structure of the embedded segment 212 can ensure that the embedded segment 212 can form a complex three-dimensional shape within the first connector 22, thereby increasing the mechanical locking points between the embedded segment 212 and the first connector 22, improving the strength of the connection, and the multi-segment bending structure can effectively resist the tensile and bending forces on the embedded segment 212, ensuring that the embedded segment 212 will not easily deform or fall out when subjected to force.

[0044] Specifically, the embedded segment 212 can be configured as a Z-shaped or multi-segment Z-shaped structure to form multiple plane and angle changes, further increasing the contact area between the embedded segment 212 and the first connector 22; the embedded segment 212 can also be configured as a wave shape so that the embedded segment 212 can form continuous undulations within the first connector 22, enhancing tensile and bending resistance. It is understood that in other embodiments, the shape of the embedded segment 212 is diverse, as long as it can meet the corresponding effect, and this application does not impose any restrictions here.

[0045] Please refer to Figures 4 to 6 The first connector 22 includes a first connector 221 and a second connector 222. The first connector 221 is integrally formed with the shape memory alloy wire 21. The second connector 222 protrudes from the first connector 221 and is integrally formed with it. The second connector 222 is detachably mounted on the housing part 1, and the surface of the first connector 221 is in contact with the surface of the housing part 1. In this embodiment, the first connector 221 and the second connector 222 are arranged at an angle. The first connector 221 is integrally formed with the shape memory alloy wire 21 to connect the shape memory alloy wire 21. The second connector 222 is detachably mounted on the housing part 1 so that the first connector 22 can connect the shape memory alloy wire 21 and the housing part 1. Since the shape memory alloy wire 21 and the first connector 22 are integrally formed, the stability of the connection between the shape memory alloy wire 21 and the housing part 1 is ensured.

[0046] Furthermore, in order to achieve a better installation fit, the housing part 1 includes a housing 11 and a limiting pin 12. The housing 11 is provided with a first mounting hole 111 for the second connecting seat 222 to pass through. The portion of the second connecting seat 222 that passes through the first mounting hole 111 and is located in the internal space of the housing 11 is provided with a second mounting hole 2221. The second mounting hole 2221 penetrates the second connecting seat 222 in a direction perpendicular to the extending direction of the second connecting seat 222. The limiting pin 12 is provided in the internal space of the housing 11, passes through the second mounting hole 2221, and abuts against the housing 11.

[0047] In some embodiments, to ensure stable installation of the housing 1 and the first connector 22, the housing 1 includes a housing 11, which has an inner side and an outer side. A first mounting hole 111 of the housing 11 penetrates the inner and outer sides of the housing 11, allowing the second connector 222 to be inserted into the first mounting hole 111. This ensures that the housing 11 and the second connector 222 are properly engaged, thus enabling the installation of the first connector 22. The installation method is simple. Specifically, the diameter of the first mounting hole 111 matches the outer diameter of the second connector 222, thereby achieving a secure fixation of the second connector 222.

[0048] To further improve the stability of the installation of the first connector 22 and the housing 11 and reduce the movement of the second connector 222 relative to the housing 11, in some embodiments, the housing part 1 also includes a limiting pin 12. The limiting pin 12 is located in the internal space of the housing 11 and is inserted into the second mounting hole 2221 of the second connector 222. The second mounting hole 2221 is located at the end of the second connector 222 that extends out of the first mounting hole 111. In actual installation, the first connector 221 and the second connector 222 are connected. The end face of the first connector 221 near the second connector 222 abuts against the outer side of the housing 11. The second mounting hole 2221 is located near the inner side of the housing 11. The limiting pin 12 passes through the second mounting hole 2221 and at least partially abuts against a portion of the housing 11, thereby limiting the second connector 222 and ensuring that the second connector 222 can be stably connected to the housing 11, thus improving the stability and durability of the ear clip-on earphone 100.

[0049] Please refer to Figure 2 The angle between the central axis of the end of the shape memory alloy wire 21 and the central axis of the second connecting seat 222 is α, 60°≤α≤90°. In the embodiments of this application, the end of the shape memory alloy wire 21 is the embedded section 212 of the shape memory alloy wire 21. The angle between the extension direction of the central axis of the embedded section 212 and the part of the main deformation section 211 near the embedded section 212 and the central axis of the second connecting seat 222 is within the range of 60° to 90°. Within this range, the angle of the transition section between the shape memory alloy wire 21 and the first connecting seat 221 is appropriate, which makes it easier for the connecting bridge 2 to fit the human ear during the adjustment process, while reducing the wear on the shape memory metal wire caused by the angle problem during the adjustment process.

[0050] In some of these embodiments, please refer to Figure 7There are two first connectors 22. One first connector 22 is integrally formed on one end of the shape memory alloy wire 21 and connected to one of the housing parts 1. The other first connector 22 is integrally formed on the other end of the shape memory alloy wire 21 and connected to the other housing part 1. In the above embodiment, each end of the shape memory alloy wire 21 is connected to a first connector 22, thus connecting the shape memory alloy wire 21 and the two housing parts 1. Since each first connector 22 is integrally formed with the shape memory alloy wire 21, the connection stability between the two ends of the shape memory alloy wire 21 and the two housing parts 1 can be guaranteed, further improving the durability of the ear clip-on earphone 100.

[0051] Based on the above embodiments, reference can be continued. Figure 7 The ear-clip earphone 100 of this application also includes a speaker assembly 3, a power supply assembly 4, and a connecting wire 5. The speaker assembly 3 and the power supply assembly 4 are respectively installed on two housing parts 1. Each first connector 22 passes through a wire hole 2211. The two ends of the connecting wire 5 pass through the wire holes 2211 of the two first connectors 22 respectively, so that the connecting wire 5 electrically connects the speaker assembly 3 and the power supply assembly 4. It can be understood that the speaker assembly 3 is used to provide sound for the ear-clip earphone 100 and complete the basic earphone function. The power supply assembly 4 is electrically connected to the speaker assembly 3 through the connecting wire 5 to supply power to the speaker assembly 3 and ensure that the speaker assembly 3 can operate normally.

[0052] In the above embodiment, the connecting wire 5 is used to connect the two housing parts 1 to ensure the coordinated operation of the speaker assembly 3 and the power supply assembly 4. In practical applications, at least a portion of the connecting wire 5 extends along the extension direction of the shape memory alloy wire 21, and both ends of the connecting wire 5 pass through the wire hole 2211 of the first connector 22 and are respectively connected to the two housing parts 1. Specifically, the first connector 22 includes a first connector 221 and a second connector 222. The wire hole 2211 is located on the first connector 221. The housing part 1 includes a housing 11. The housing 11 is also provided with mounting holes corresponding to the wire hole 2211. The connecting wire 5 passes through the mounting holes and extends into the housing 11 to connect the speaker assembly 3 and the power supply assembly 4, ensuring the normal operation of the ear clip-on headphones 100.

[0053] Furthermore, the connecting bridge 2 also includes an outer sheath 23, which covers the outer surface of the shape memory alloy wire 21 and also covers the outer surface of the portion of the first connector 22 used to connect with the shape memory alloy wire 21. The outer sheath 23 serves to isolate the shape memory alloy wire 21 from the outside environment, thereby protecting the shape memory alloy wire 21. In addition, since the outer sheath 23 also covers at least the outer surface of the portion of the first connector 22 used to connect with the shape memory alloy wire 21, it further limits the relative position between the first connector 22 and the shape memory alloy wire 21, improving the connection strength between them. In the above embodiment, the outer sheath 23 also covers the side of the first connector 22 closest to the outside, thereby maintaining the consistency of the appearance of the connecting bridge 2 and providing a better sealing effect, reducing the amount of dust entering the ear clip-on earphone 100.

[0054] In this embodiment, the outer layer 23 is made of a soft material and wraps the shape memory alloy wire 21, thereby ensuring that the contact part between the ear clip earphone 100 and the human ear is soft and improving the wearing experience of the ear clip earphone 100.

[0055] It is understandable that the outer sheath 23 is made of materials such as silicone, thermoplastic polyurethane (TPU), thermoplastic vulcanized rubber (TPV), and thermoplastic polyester elastomer (TPEE). The outer sheath 23 has good elasticity and durability, and can better protect the connecting wire 5 and the shape memory alloy wire 21.

[0056] In some embodiments, the outer sheath 23 also covers the connecting wire 5, and the connecting wire 5 and the shape memory alloy wire 21 are spaced apart and do not affect each other.
