Description

[Technical field]

[0001] The present invention relates to an anti-loss rope, and more particularly to an anti-loss rope for wireless in-ear audio devices or eyeglass frames. [Background technology]

[0002] A wireless Bluetooth earphone usually includes an earplug part that covers the user's ear and a cord bushing that is exposed outside the user's ear. A conventional anti-loss rope is made of an elastic rope, and the anti-loss rope includes two closed storage rings formed by encircling both ends of the elastic rope, and a middle section located between the two storage rings and integrally connected to the two storage rings, and each of the storage rings is used to store the cord bushing of the wireless Bluetooth earphone. In order to connect the storage ring to the cord bushing, the storage ring needs to be covered over the cord bushing from bottom to top. Summary of the Invention [Problem to be solved by the invention]

[0003] However, in the process of covering the containing ring from bottom to top on the cord bush, the elasticity of the loss prevention rope causes the containing ring to be attached to the outer surface of the cord bush, and as the containing ring moves from bottom to top, it rotates on the outer surface of the cord bush. As the containing ring rotates, the intermediate section connected to it is also linked to rotate the same number of times or more, and the intermediate section becomes entangled in the containing ring, resulting in a situation in which the loss prevention rope becomes complicatedly tangled.

[0004] Similarly, since the two storage rings of the anti-loss rope are also used to store the two temples of the eyeglass frame, the elasticity of the anti-loss rope causes the storage rings to be attached to the outer surface of the temples, and similarly, the middle section is entangled inside the storage rings, resulting in the problem of the anti-loss rope becoming complicatedly tangled.

[0005] Therefore, the present inventors believed that the above-mentioned drawbacks could be improved, and as a result of extensive research, they came to propose the present invention, which effectively improves the above-mentioned problems through rational design.

[0006] The present invention has been made in consideration of these circumstances, and its purpose is to provide an anti-loss rope that reduces the number of turns or is less likely to become tangled when wrapped around the outside of an object such as the cord bush of a wireless Bluetooth (registered trademark) earphone or the temple of an eyeglass frame.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0035] The present invention will be described below through embodiments of the invention, but the following embodiments do not limit the scope of the invention according to the claims. Furthermore, not all of the combinations of features described in the embodiments are necessarily essential to the solution of the invention.

[0036] First, the loss prevention rope according to the present invention will be described with reference to Figs. 1 to 39. There are eight embodiments of the loss prevention rope according to the present invention, and the loss prevention rope is used to connect a first object to a second object, and in the first to eighth embodiments of the present invention, the loss prevention rope is connected to at least one wireless in-ear audio device 7. In this case, one of the wireless in-ear audio devices 7 is the first object, and the second object may be another one of the wireless in-ear audio devices 7, or may be a clamping part 8 connected to the clothes worn by the user on the body, the user's earlobe, or the user's neck or arm by the loss prevention rope to prevent the wireless in-ear audio device 7 from falling off the user's ear and being lost, or to prevent the wireless in-ear audio device 7 from being lost when removed from the user's ear.

[0037] As shown in Figures 2, 10, 12, 17, 19, 26, 30 and 35, the wireless in-ear audio device 7 includes an earplug part 71 that covers the user's ear and an ear handle 72 that is exposed outside the user's ear. The ear handle 72 is used to connect to the anti-loss rope. In the first to eighth embodiments, the ear handle 72 is installed in a cylindrical shape and is used to connect to the anti-loss rope. In other embodiments, the ear handle 72 is installed in a rectangular shape.

[0038] As shown in Figures 1, 9, 11, 16, 18, 24, 29 and 34, the anti-loss rope according to the present invention comprises at least one noose unit 1 and a vertically elongated connecting line 2 connected to the noose unit 1. The noose unit 1 is directly or indirectly connected to one end of the connecting line 2, and the noose unit 1 is used to cover the outside of the ear handle 72 (first object) of the wireless in-ear audio device 7 (see Figures 2, 8, 10, 15, 17, 23, 27 and 33 for details), and the other end of the connecting line 2 is connected to the second object. As can be seen from this, the connecting line 2 is used to connect the wireless in-ear audio device 7 and the second object to each other.

[0039] As shown in Figures 1, 9, 11, 16, 18, 24, 29 and 34, the noose unit 1 according to the present invention comprises a flexible sleeve 11 and an elastic wire 12 passing through the flexible sleeve 11 along the extension direction of the length of the flexible sleeve 11, and the elastic wire 12 is used to directly or indirectly connect to the connection line 2. The length of the elastic wire 12 is longer than the length of the flexible sleeve 11, and the flexible sleeve 11 is displaced along the extension direction of the length of the elastic wire 12. The flexible sleeve 11 includes two ends 111 located at both ends of the extension direction of the length of the flexible sleeve 11 and a through hole 112 located inside the flexible sleeve 11 and extending along the extension direction of the length of the flexible sleeve 11, and the through hole 112 is used to pass the elastic wire 12 through. The elastic wire 12 has a housing portion 121 housed in the through hole 112 and an exposed portion 122 connected to both ends of the housing portion 121, the exposed portion 122 is exposed to the outside of the flexible sleeve 11, and a closed coil structure is formed by connecting the front and rear of the exposed portion 122 and the housing portion 121. In other words, the elastic wire 12 has a coil structure formed by being surrounded by the exposed portion 122 and the housing portion 121, and the part of the elastic wire 12 housed in the through hole 112 is defined as the housing portion 121, and the part protruding into the flexible sleeve 11 is defined as the exposed portion 122. The coil structure formed by the exposed portion 122 and the accommodating portion 121 surrounds the flexible sleeve 11, which is covered on the outside of the accommodating portion 121, and the exposed portion 122 surrounds the coil structure to form an accommodating space 13, which is used to accommodate the ear handle 72, the noose unit 1 is covered by the ear handle 72, and the exposed portion 122 and the connecting wire 2 are directly or indirectly connected.

[0040] As shown in Figures 2, 10, 12, 17, 19, 26, 30 and 35, the flexible sleeve 11 according to the present invention is used to surround the ear handle 72 and directly contacts the surface of the ear handle 72. The flexible sleeve 11 is soft, so it will not damage the ear handle 72 or the surface it contacts. The elastic wire 12 passes through the flexible sleeve 11, and the flexible sleeve 11 is deformed according to the direction of extension of the length of the elastic wire 12, and the elasticity of the elastic wire 12 allows the flexible sleeve 11 to be attached to the surface of the ear handle 72. Similarly, the elastic wire 12 is also installed to surround the ear handle 72, and the elasticity of the elastic wire 12 allows the noose unit 1 to be covered outside the ear handles 72 with different circumferential lengths, improving the compatibility of the anti-lost rope. When the ear handle 72 is not inserted into the accommodating space 13, the accommodating space 13 is irregularly installed, and when the ear handle 72 is inserted into the accommodating space 13, the elasticity of the elastic wire 12 causes the accommodating space 13 to expand from its original irregular shape to a shape that fits the outer surface of the ear handle 72, and the noose unit 1 is covered by the wireless in-ear audio device 7 (see Figure 4).

[0041] As shown in Figures 2, 10, 12, 17, 19, 26, 30 and 35, the flexible sleeve 11 according to the present invention is attached to the outer surface of the ear handle 72 by the elasticity of the elastic wire 12, the flexible sleeve 11 is covered by the ear handle 72 from bottom to top, and the flexible sleeve 11 rotates around the circumference in the direction of extension of its length. However, since the flexible sleeve 11 and the elastic wire 12 are installed separately, the flexible sleeve 11 rotates around the elastic wire 12, and the elastic wire 12 is difficult to rotate following the flexible sleeve 11 covered therearound, and the connecting wire 2 directly or indirectly connected to the elastic wire 12 is prevented from being entangled with the accommodating space 13.

[0042] As shown in Figures 1, 9, 11, 16, 18, 24, 29 and 34, in the first to eighth embodiments, the flexible sleeve 11 has elasticity and contracts to a certain degree along the direction of extension of its length, and the elasticity is smaller than that of the elastic wire 12. Of course, the flexible sleeve 11 also has a certain degree of elasticity in the cross-sectional direction perpendicular to its length. In other embodiments, the flexible sleeve 11 does not need to have elasticity.

[0043] As shown in Figures 3, 4, 10, 13, 14, 17, 20, 26, 31 and 37, the length of the flexible sleeve 11 according to the present invention is not less than half the circumference of the ear handle 72. In the first to eighth embodiments, the length of the flexible sleeve 11 according to the present invention is more than half the circumference of the ear handle 72, specifically, the length of the flexible sleeve 11 is 20mm to 22mm, which is adapted to the ear handle 72 of the wireless in-ear audio device 7 in the current market.

[0044] As shown in Figures 1, 9, 11, 16, 18, 24, 29 and 34, in the first to eighth embodiments, the elastic wire 12 is a rubber cord, which is formed by adopting imported rubber thread as a core and doubly covering it with high-quality double-fiber thread (polyester thread or nylon thread, also known as Tedron thread or nylon thread).

[0045] As shown in Figures 1, 9, 11, 16, 18, 24, 29 and 34, in the first to eighth embodiments, the connecting line 2 has elasticity, which generates a cushioning effect when the wireless in-ear audio device 7 falls off from the user's ear, prevents the user's ear from being damaged when the wireless in-ear audio device 7 is pulled too hard, reduces the resulting pain, and prevents the wireless in-ear audio device 7 from falling directly onto other objects due to gravity and being damaged.

[0046] 5, the flexible sleeve 11 is arranged so that the cross section perpendicular to the lengthwise extension direction thereof is ring-shaped, the inner diameter of the ring is 1 mm, and the outer diameter of the ring is not greater than 2 mm. The flexible sleeve 11 is arranged so that the cross section perpendicular to the lengthwise extension direction thereof is ring-shaped. As can be seen from this, the through hole 112 is circular in cross section perpendicular to the lengthwise extension direction of the flexible sleeve 11, the diameter of the through hole 112 is kept constant along the lengthwise extension direction of the flexible sleeve 11, and the through hole 112 is a circular through hole 112 whose diameter is kept constant along the lengthwise extension direction of the flexible sleeve 11, and the diameter of the through hole 112 is 1 mm. The elastic wire 12 has a circular cross-sectional shape perpendicular to the extension direction of the elastic wire 12, the cross-sectional shape of the elastic wire 12 is kept consistent along the extension direction of the elastic wire 12, the diameter of the circular cross-section of the elastic wire 12 is less than 1 mm, the elastic wire 12 is housed in the through-hole 112, and the flexible sleeve 11 is displaced along the extension direction of the elastic wire 12. The structure of the flexible sleeve 11 and the structure of the elastic wire 12 in the above portion are applicable to the first to eighth embodiments of the present invention.

[0047] As shown in Fig. 8, in another embodiment, the cross-sectional shape of the through hole 112 perpendicular to the extension direction of the length of the flexible sleeve 11 is different from the cross-sectional shape of the elastic wire 12 perpendicular to the extension direction of the length of the elastic wire 12. Specifically, in another embodiment, the cross-sectional shape of the through hole 112 perpendicular to the extension direction of the length of the flexible sleeve 11 is circular, the cross-sectional shape of the through hole 112 is kept consistent along the extension direction of the length of the flexible sleeve 11, the through hole 112 is a circular through hole 112 whose diameter is kept constant along the extension direction of the length of the flexible sleeve 11, and the diameter of the through hole 112 is 1 mm. The cross-sectional shape of the elastic wire 12 perpendicular to the extension direction of the length of the elastic wire 12 is rectangular, specifically, rectangular, and the cross-sectional shape of the elastic wire 12 is kept consistent along the extension direction of the length of the elastic wire 12. Specifically, the long side of the rectangular cross section of the elastic wire 12 is 0.9 mm, and the short side is 0.6 mm. In this embodiment, the rectangular cross section of the elastic wire 12 is in flat contact with the outer surface of the ear handle 72, so that the elastic wire 12 having a rectangular cross section is less likely to rotate along the flexible sleeve 11 having the circular through hole 112. The structure of the flexible sleeve 11 and the structure of the elastic wire 12 in the above-mentioned portion are applicable to all embodiments of the present invention.

[0048] <First Example> The configuration of the first embodiment of the present invention is shown in Figures 1 to 5. The anti-loss rope according to this embodiment has two noose units 1 and the connecting wire 2 directly connected to the two noose units 1, specifically, the exposed portion 122 of the noose unit 1 has a first section 1221 extending from one of the end portions 111 and a second section 1222 extending from the other end portion 111, the first section 1221 and the second section 1222 are fixedly connected to form a connecting portion 123, both ends of the connecting wire 2 are formed by being integrally extended from the first section 1221 of the corresponding noose unit 1, respectively, and the connecting wire 2 is directly connected to the two noose units 1. In this embodiment, the two elastic wires 12 and the connecting wire 2 of the two noose units 1 are different parts of a single wire that is continuously extended. In this embodiment, the connection part 123 is a knot formed by the first section 1221 and the second section 1222 surrounding each other, and a user can adjust the size of the receiving space 13 by opening the knot to accommodate different sizes of the ear handle 72. Of course, in a general situation, due to the elasticity of the elastic wire 12, there is no need to open the connection part 123 which is a knot.

[0049] 2, in the first embodiment, the anti-loss rope is connected to the two wireless in-ear audio devices 7, the first object and the second object are both the wireless in-ear audio devices 7, the two wireless in-ear audio devices 7 are respectively covered in the two accommodation spaces 13 formed by the two noose units 1, and when the two earplug parts 71 of the two wireless in-ear audio devices 7 cover the two ears of the user, the length of the connecting line 2 is sufficient to wrap around the back of the user's neck. Even if the two wireless in-ear audio devices 7 both fall off the user's ears, the two wireless in-ear audio devices 7 will not be directly lost because the connecting line 2 is hung around the user's neck.

[0050] As shown in Fig. 6, in the first embodiment, the anti-loss rope is used to connect to a spectacle frame 9, and the spectacle frame 9 includes two rims 91 arranged to face each other at a distance, a bridge 92 located between the two rims 91, and two temples 93 located on both sides of the two rims 91, and the bridge 92 is connected to the two rims 91, and the two temples 93 are connected to the two rims 91 in a one-to-one correspondence, and the two temples 93 are arranged to face each other. The two rims 91 are arranged to face each other on both eyes of the user, the bridge 92 is installed above the bridge of the user's nose, and the two temples 93 are installed above the ears of the user in a one-to-one correspondence. The two temples 93 are used to connect to the anti-loss rope, and specifically, the two temples 93 are accommodated in the two accommodation spaces 13 formed by the two nose units 1 in a one-to-one correspondence. That is, the two noos units 1 are covered by the two temples 93, the first object and the second object are the two temples 93, and when the user is wearing the eyeglass frame 9, the length of the connecting wire 2 is sufficient to wrap around the back of the user's neck, and when the user removes the eyeglass frame 9 from the user's ears and nose bridge, the eyeglass frame 9 will not be directly lost because the connecting wire 2 is hung around the user's neck.

[0051] As shown in Fig. 6 and Fig. 7, in this embodiment, the flexible sleeve 11 is used to surround the temple 93 and directly contacts the surface of the temple 93. Since the flexible sleeve 11 is soft, the flexible sleeve 11 does not damage the temple 93 and the surface it contacts. The elastic wire 12 passes through the flexible sleeve 11, and the flexible sleeve 11 is deformed according to the extension direction of the length of the elastic wire 12, and the elasticity of the elastic wire 12 allows the flexible sleeve 11 to be attached to the surface of the temple 93. Similarly, the elastic wire 12 is also installed to surround the temple 93, and the elasticity of the elastic wire 12 allows the noose unit 1 to be covered outside the temple 93 with different circumferential lengths, thereby improving the adaptability of the anti-lost rope. When the temple 93 is not inserted into the accommodating space 13, the accommodating space 13 is installed irregularly, and when the temple 93 is inserted into the accommodating space 13, the accommodating space 13 expands from its original irregular shape to a shape that fits the outer surface of the temple 93 due to the elasticity of the elastic wire 12, and the noos unit 1 is covered by the temple 93.

[0052] 6 and 7, in this embodiment, the flexible sleeve 11 is attached to the outer surface of the temple 93 by the elasticity of the elastic wire 12, the flexible sleeve 11 is covered on the temple 93 from the outside to the inside, and the flexible sleeve 11 rotates around the temple 93 in the direction of its length. However, since the flexible sleeve 11 and the elastic wire 12 are installed separately, the flexible sleeve 11 rotates around the elastic wire 12, and the elastic wire 12 is difficult to rotate following the flexible sleeve 11 covered thereon, so that the connecting line 2 directly or indirectly connected to the elastic wire 12 is prevented from being entangled with the accommodating space 13, and the connecting line 2 and the elastic wire 12 are prevented from being entangled with each other.

[0053] 6 and 7, the length of the flexible sleeve 11 is not less than half the circumference of the temple 93. In this embodiment, the length of the flexible sleeve 11 is more than half the circumference of the temple 93.

[0054] As shown in Figures 6 and 7, the connecting wire 2 has elasticity, which generates a cushioning effect when the eyeglass frame 9 falls from the user's face, and prevents the eyeglass frame 9 from injuring the user's neck even if it is pulled strongly, reducing the pain caused by the injury, and preventing the eyeglass frame 9 from falling directly onto other objects due to gravity and being damaged.

[0055] In another embodiment, when the elastic wire 12 is installed with a rectangular cross-section, the rectangular cross-section of the elastic wire 12 is in flat contact with the outer surface of the temple 93, so that the elastic wire 12 with a rectangular cross-section is less likely to rotate along with the flexible sleeve 11 having a circular through hole 112.

[0056] <Second Example> The configuration of the second embodiment of the present invention is shown in Fig. 9 to Fig. 10. The loss prevention rope according to this embodiment has the nous unit 1 and the connection line 2 directly connected to the nous unit 1. In this embodiment, the first object is the wireless in-ear audio device 7, and the second object is the clamping part 8, which is used to clamp the device to the clothes worn by the user or the user's earlobe. If the wireless in-ear audio device 7 falls off the user's ear, the wireless in-ear audio device 7 indirectly connected to the clamping part 8 will not be directly lost because the clamping part 8 is clamped to the user's clothes or the user's earlobe. In this embodiment, the nous unit 1 and the clamping part 8 are directly connected to both ends of the connection line 2, respectively, and the connection method between the one end to which the connection line 2 and the nous unit 1 are connected and the nous unit 1 is the same as that of the first embodiment of the present invention. That is, one end to which the connecting line 2 and the noose unit 1 are connected is formed by extending integrally from the first stage 1221 of the exposed portion 122, for specific details, refer to the first embodiment of the present invention, and the description thereof will not be repeated here.

[0057] <Third Example> The configuration of a third embodiment of the present invention is shown in Figures 11 to 14. The loss prevention rope according to this embodiment has two of the noose units 1, the connection line 2, and two collars 3 for indirectly connecting the two noose units 1 and the connection line 2. Specifically, both ends of the connection line 2 are directly connected to the two collars 3, respectively, and the two collars 3 are directly connected to the exposed parts 122 of the two noose units 1 in a one-to-one correspondence, and the connection line 2 and the two noose units 1 are indirectly connected.

[0058] 12, in the third embodiment, the anti-loss rope is connected to the two wireless in-ear audio devices 7, i.e., the first object and the second object are both the wireless in-ear audio devices 7, and the two wireless in-ear audio devices 7 are respectively covered in the two accommodation spaces 13 formed by the two noose units 1. When the two earplug parts 71 of the two wireless in-ear audio devices 7 cover both ears of the user, the length of the connecting line 2 is sufficient to wrap around the back of the user's neck, so even if both of the two wireless in-ear audio devices 7 fall out of the user's ears, the two wireless in-ear audio devices 7 will not be directly lost because the connecting line 2 is hung around the user's neck.

[0059] The two noose units 1 of the loss prevention rope according to the third embodiment can be installed on the two temples 93 of the eyeglass frame 9 according to the first embodiment in a one-to-one correspondence. Specifically, the two accommodation spaces 13 of the loss prevention rope according to the third embodiment can also accommodate the two temples 93 of the eyeglass frame 9 in a one-to-one correspondence, and the connection line 2 is wound around the back of the user's neck and connected to the user's neck, preventing the eyeglass frame 9 from being directly lost when the user removes the eyeglass frame 9.

[0060] As shown in Figures 11, 13 and 14, in the third embodiment, each of the collars 3 has an inner end 31 and an outer end 32. Each of the collars 3 is fitted over the exposed portion 122 of the corresponding noose unit 1 and rotates around the exposed portion 122, and the exposed portion 122 passes through the collar 3 and is directly connected to the collar 3. The thickness T2 between the inner end 31 and the outer end 32 is not thicker than the linear distance D1 that the outer circumferential surface of the flexible sleeve 11 exceeds the outer circumferential surface of the exposed portion 122, and the thickness T1 of the tube wall of the flexible sleeve 11 is thicker than the thickness T2 between the inner end 31 and the outer end 32, so that the collar 3 is engaged between the outer circumferential surface of the exposed portion 122 and the outer surface of the ear handle 72 or between the outer circumferential surface of the exposed portion 122 and the outer surface of the ear handle 72, and easily rotates. One end of the connecting line 2 passes through the collar 3 and is installed to surround a part of the circumferential direction of the collar 3, directly connected to the collar 3, and rotates around the collar 3. In other words, the connecting line 2 is covered by the collar 3, and the noose unit 1 is connected to the connecting line 2 by the collar 3, so that when the elastic wire 12 of the noose unit 1 rotates, the connecting line 2, which is installed separately from the elastic wire 12, follows the elastic wire 12 and becomes difficult to rotate or does not rotate at all, and even interlocks with the collar 3 to rotate, and the connecting line 2 is held at a specific position in the circumferential extension direction of the collar 3 by the action of gravity during the rotation of the collar 3, and the connecting line 2 moves along the circumferential extension direction of the collar 3, which further prevents the connecting line 2 from being entangled. In addition, in this embodiment, the collar 3 passes through the elastic wire 12 and the connecting line 2, and the corresponding portion of the elastic wire 12 and the corresponding portion of the connecting line 2 are both located within the inner end 31 of the collar 3, and a gap is maintained between the elastic wire 12 and the connecting line 2, thereby preventing the elastic wire 12 and the connecting line 2 from becoming entangled with each other.

[0061] 11, 13 and 14, in the third embodiment, the elastic wire 12 is an elastic wire having two free ends, and the coil structure formed by fixing the two free ends to each other forms a connection part 123, and the connection part 123 is located at the exposed part 122. In this embodiment, the connection part 123 is a knot. In another embodiment, the connection part 123 is located at the accommodation part 121, i.e., accommodated in the through hole 112 of the flexible sleeve 11, to prevent the connection part 123 from interfering with the collar 3, further preventing the collar 3 from being unable to rotate, or preventing the connection part 123 of the elastic wire 12 from interfering with the connecting line 2 and becoming entangled.

[0062] In the example of Figure 15, in the third embodiment, the thickness T3 between the inner ring end 31 and the outer ring end 32 is less than the linear distance D2 that the outer surface of the flexible sleeve 11 exceeds the outer surface of any one of the exposed portions 122, and the collar 3 engages between the outer surface of the exposed portion 122 and the outer surface of the ear handle 72 and is capable of rotating.

[0063] As shown in Figures 11, 13 and 14, in the third embodiment, the collar 3 is made of a hard non-metallic material and has a low friction coefficient. Specifically, the material of the collar 3 is ceramic or polytetrafluoroethylene, and the outer surface of the collar 3 is made smooth. The friction between the collar 3 and the exposed portion 122 is very small, so that a slip phenomenon occurs and the collar 3 is interlocked with the exposed portion 122 and follows it, making it difficult to rotate or not to rotate at all, even if the exposed portion 122 rotates. In addition, the smooth outer surface of the collar 3 prevents the collar 3 from rubbing the outer surface of the ear handle 72 or the outer surface of the temple 93 when the collar 3 rotates around the exposed portion 122.

[0064] <Fourth Example> The configuration of the fourth embodiment of the present invention is shown in Fig. 16 to Fig. 17. The loss prevention rope according to this embodiment has the noose unit 1, the connection line 2, and the collar 3 indirectly connecting the noose unit 1 and the connection line 2. In this embodiment, the first object is the wireless in-ear audio device 7, and the second object is the clamping part 8 as in the second embodiment of the present invention, and the clamping part 8 is used to clamp the wireless in-ear audio device 7 on the clothes worn by the user or on the user's earlobe, etc., to prevent the wireless in-ear audio device 7 from being directly lost when it falls off the user's ear. In this embodiment, one end of the connection line 2 is indirectly connected to the noose unit 1 by the collar 3, and the other end of the connection line 2 is directly connected to the clamping part 8. The connection relationship between the collar 3 and the noose unit 1 and the connection relationship between the connection line 2 and the collar 3 are the same as those in the third embodiment of the present invention, so that the description thereof will not be repeated here.

[0065] <Fifth Example> The configuration of the fifth embodiment of the present invention is shown in Figures 18 to 23. The difference between the loss prevention rope according to the fifth embodiment of the present embodiment and the loss prevention rope according to the third embodiment is that each of the flexible sleeves 11 of the loss prevention rope according to the fifth embodiment includes a tube portion 11A and a block portion 11B formed to protrude outward from the tube portion 11A, the two end portions 111 are located at both ends of the extension direction of the length of the tube portion 11A, the through hole 112 is located inside the tube portion 11A and extends along the extension direction of the length of the tube portion 11A, and the block portion 11B is located outside the through hole 112. The block portion 11B is provided with a storage space 113 for storing the magnetic element 4, and the storage space 113 is installed at a distance from the through hole 112, that is, they are not communicated with each other. Each of the noose units 1 is further provided with a magnetic element 14, which is provided in the corresponding flexible sleeve 11 and stored in the corresponding storage space 113, and the block portion 11B and the magnetic element 4 stored in the block portion 11B are located outside the corresponding storage space 13. The storage space 113 penetrates the flexible sleeve 11 and is used to attach the magnetic element 14 to the storage space 113 from the outside to the inside. The user can take out and replace the magnetic element 14 through the storage space 113. The two magnetic elements 14 of the two noose units 1 are attached to each other and joined, and when the two magnetic elements 14 are attached to each other and joined, the connecting wire 2 surrounds them to form a winding space 21. In this embodiment, the two magnetic elements 14 provided in the two noose units 1 may be magnets, or one may be a magnet and the other may be made of a material that is attached to a magnet. The remaining structure is the same as that of the third embodiment of the present invention, and therefore the description thereof will not be repeated here.

[0066] As shown in Figures 20 and 21, when the flexible sleeve 11 rotates around the elastic wire 12, the blocking portion 11B abuts against the outer surface of the ear handle 72, thereby blocking the flexible sleeve 11 from rotating excessively. At the same time, the blocking portion 11B is maintained in abutment against the outer surface of the ear handle 72 and slides on the outer surface of the ear handle 72, further preventing rotation of the elastic wire 12, further preventing rotation of the collar 3 connected to the elastic wire 12, and further preventing the connecting line 2 connected to the collar 3 from becoming tangled or entering the storage space 13.

[0067] As shown in FIG. 22, in the fifth embodiment, when the two wireless in-ear audio devices 7 covered in the two noose units 1 are both removed from the user's ears, that is, when the user no longer uses the two wireless in-ear audio devices 7, the connecting wire 2 is wound around the back of the user's neck, the two wireless in-ear audio devices 7 are hung on the user's chest, and the two magnetic elements 14 of the two noose units 1 are attracted to each other, so that the connecting wire 2 surrounds and forms the winding space 21. At this time, the user's neck is accommodated just right in the winding space 21, and the length of the connecting wire 2 is longer than the user's neck circumference, so that the two wireless in-ear audio devices 7 connected to the connecting wire 2 are prevented from being lost by hanging the connecting wire 2 around the user's neck. At this time, the two wireless in-ear audio devices 7 can be hung on the user's chest or back as needed.

[0068] 23, in the fifth embodiment, when the two wireless in-ear audio devices 7 covered in the two noose units 1 are detached from the user's ears, that is, when the user no longer uses the two wireless in-ear audio devices 7, the connecting wire 2 is first wrapped around the user's arm, and the length of the connecting wire 2 can be wrapped around the user's arm once or multiple times, so that the length of the connecting wire 2 is longer than the circumference of the user's arm, and finally, the two flexible sleeves 11 of the two noose units 1 are exposed, and the two magnetic elements 14 are attracted to each other and joined to form the winding space 21. At this time, the user's arm is accommodated in the winding space 21 formed by surrounding the connecting wire 2, and the anti-loss rope and the two wireless in-ear audio devices 7 connected to it are hung on the user's arm, so that the two wireless in-ear audio devices 7 will not be lost. Of course, in this embodiment, when the connecting line 2 is not wrapped around the user's arm, the length of the connecting line 2 is sufficient for inserting two of the wireless in-ear audio devices 7 into the user's ears at the same time.

[0069] Similarly, in the fifth embodiment, the two noose units 1 of the loss prevention rope can be covered with the two temples 93 of the eyeglass frame 9 according to the first embodiment in a one-to-one correspondence. Specifically, the two accommodation spaces 13 of the loss prevention rope according to the fifth embodiment accommodate the two temples 93 of the eyeglass frame 9 in a one-to-one correspondence, and the connection line 2 is wound around the back of the user's neck and connected to the user's neck, preventing the eyeglass frame 9 from being directly lost when the user removes the eyeglass frame 9.

[0070] Similarly, the blocking portion 11B abuts against the outer surface of the temple 93 to block the flexible sleeve 11 from rotating excessively, and at the same time, the blocking portion 11B maintains its abutment against the outer surface of the temple 93 and slides against the outer surface of the temple 93, further preventing the elastic wire 12 from rotating, further preventing the collar 3 connected to the elastic wire 12 from rotating, and further preventing the connecting line 2 connected to the collar 3 from getting tangled or entering the accommodating space 13.

[0071] <Sixth Example> The configuration of the sixth embodiment of the present invention is shown in Fig. 24 to Fig. 28. The difference between the loss prevention rope according to the sixth embodiment of the present embodiment and the loss prevention rope according to the first embodiment is that the loss prevention rope further includes a bundling member 4 connected to the connection line 2, and the bundling member 4 includes a positioning portion 41 and an engagement portion 42. The positioning portion 41 is provided with a space limiting portion 411 for passing the connection line 2 through, the positioning portion 41 is provided so as to surround the periphery of the connection line 2, the size of the space limiting portion 411 perpendicular to the extension direction of the length of the connection line 2 is slightly larger, equal to, or slightly smaller than the size of the connection line 2 perpendicular to the extension direction of its length, and the bundling member 4 slides along the extension direction of the length of the connection line 2. The engagement portion 42 is provided with an engagement space 421 for passing the connection line 2 through and a cutout portion 422 communicating with the engagement space 421, and the engagement space 421 is communicated with the outside world via the cutout portion 422. The connecting line 2 enters the engagement space 421 through the notch 422 and engages with the engagement portion 42. The engagement portion 42 is disposed so as to surround a partial circumference of the connecting line 2, a portion of the circumference of the connecting line 2 is exposed to the outside through the notch 422, and the space limiting portion 411 and the engagement space 421 are disposed at a distance from each other. The connecting line 2 is provided with a first stage 22 accommodated in the space limiting portion 411 and a second stage 23 accommodated in the engagement space 421, and the connecting line 2 is provided with an enclosing space 24 between the first stage 22 and the second stage 23. The remaining structure is the same as that of the first embodiment of the present invention, and therefore the description thereof will not be repeated here.

[0072] As shown in FIG. 27, in the sixth embodiment, when the two wireless in-ear audio devices 7 covered in the two noose units 1 are both removed from the user's ears, that is, when the user no longer uses the two wireless in-ear audio devices 7, the connecting wire 2 is first wrapped around the back of the user's neck, the converging member 4 connected to the connecting wire 2 is moved to the front of the user's neck, and a part of the connecting wire 2 is inserted from the notch 422 into the engagement space 421 and engaged with the engagement part 42, thereby surrounding the connecting wire 2 to form the surrounding space 24. At this time, the user's neck is accommodated in the surrounding space 24, and the length of the connecting wire 2 is longer than the circumference of the user's neck, so that when the connecting wire 2 is hung around the user's neck, the two wireless in-ear audio devices 7 are connected to the connecting wire 2 hung around the user's neck and will not be lost. In this case, the user can hang the two wireless in-ear audio devices 7 on the front chest or back of the user as necessary.

[0073] As shown in Fig. 28, in the sixth embodiment, when the two wireless in-ear audio devices 7 covered in the two noose units 1 are detached from the user's ears, that is, when the user no longer uses the two wireless in-ear audio devices 7, the connecting wire 2 is first wrapped around the user's arm, the converging member 4 connected to the connecting wire 2 is moved to the outside of the arm, and a part of the connecting wire 2 is inserted from the notch 422 into the engagement space 421 and engaged with the engagement part 42, so that the connecting wire 2 surrounds the surrounding space 24. At this time, the user's arm is located in the surrounding space 24, and the length of the connecting wire 2 in the surrounding space 24 is sufficient to wrap around the user's arm once or multiple times, so that the connecting wire 2 is hung around the user's arm, and the two wireless in-ear audio devices 7 are not lost. In this case, the length of the connecting wire 2 is longer than the circumference of the user's arm.

[0074] Similarly, in the sixth embodiment, the two noose units 1 of the loss prevention rope can be installed on the two temples 93 of the eyeglass frame 9 according to the first embodiment in a one-to-one correspondence. Specifically, the two accommodation spaces 13 of the loss prevention rope according to the sixth embodiment can also accommodate the two temples 93 of the eyeglass frame 9 in a one-to-one correspondence, and the connection line 2 is wound around the back of the user's neck and connected to the user's neck, thereby preventing the eyeglass frame 9 from being directly lost when the user removes the eyeglass frame 9.

[0075] In other embodiments, the converging member 4 may be connected to the connecting line 2 in the second, third and fourth embodiments, and the connection method between the converging member 4 and the connecting line 2 is the same as in the sixth embodiment, so the description thereof will not be repeated here.

[0076] <Seventh Example> The configuration of the seventh embodiment of the present invention is shown in Figures 29 to 33. The difference between the loss prevention rope according to the seventh embodiment of the present embodiment and the loss prevention rope according to the first embodiment is that the loss prevention rope further includes two magnetic elements 5 covered on the connection line 2, each of the magnetic elements 5 is provided with an insertion hole 51 for passing the connection line, the cross-sectional area of ​​the two insertion holes 51 is slightly larger than the cross-sectional area of ​​the connection line 2 in a direction perpendicular to the extension direction of the length of the connection line 2, and the two magnetic elements 5 slide along the extension direction of the length of the connection line 2. The connection line 2 is provided with two protrusion limiting parts 25 spaced apart along the extension direction of the length, and the two protrusion limiting parts 25 are provided adjacent to both ends of the connection line 2, respectively. As can be seen from the first embodiment, both ends of the connection line 2 are directly connected to the two noose units 1, respectively, so that the two protrusion limiting portions 25 are also provided adjacent to the two noose units 1, respectively, and in the extension direction of the length of the connection line 2, one of the magnetic elements 5 is restricted in position between one of the protrusion limiting portions 25 and one of the noose units 1 along the extension direction of the length of the connection line 2, and the other of the magnetic elements 5 is restricted in position between the other of the protrusion limiting portions 25 and the other of the noose units 1 along the extension direction of the length of the connection line 2. In a direction perpendicular to the extension direction of the length of the connection line 2, the cross-sectional area of ​​any one of the protrusion limiting portions 25 is larger than the cross-sectional area of ​​any one of the insertion holes 51, and any one of the magnetic elements 5 is restricted to move between the two protrusion limiting portions 25 along the extension direction of the length of the connection line 2. The two magnetic elements 5 can be attracted to each other and joined together, so that the portion of the connecting line 2 located between the two protrusion limiting portions 25 is surrounded to form an enclosing space 24. In this embodiment, the protrusion limiting portion 25 is a knot structure formed by connecting the connecting line 2. In this embodiment, the two magnetic elements 5 may both be magnets, or one may be a magnet and the other may be made of a material that is attracted to a magnet. The remaining structure is the same as that of the first embodiment of the present invention, and therefore the description thereof will not be repeated here.

[0077] As shown in FIG. 32, in the seventh embodiment, when the two wireless in-ear audio devices 7 covered in the two noose units 1 are both removed from the user's ears, that is, when the user no longer uses the two wireless in-ear audio devices 7, the connecting wire 2 is first wrapped around the back of the user's neck, the two wireless in-ear audio devices 7 are hung on the user's chest, and the two magnetic elements 5 are attracted to each other, thereby surrounding the portion of the connecting wire 2 located between the two protrusion limiting parts 25, forming the surrounding space 24, and the user's neck is accommodated snugly in the surrounding space 24. Since the length of the connecting wire 2 is longer than the user's neck circumference, the two wireless in-ear audio devices 7 connected to the connecting wire 2 are prevented from being lost by hanging the connecting wire 2 around the user's neck. At this time, the two wireless in-ear audio devices 7 may be hung on the user's chest or back as needed.

[0078] As shown in FIG. 33, in the seventh embodiment, when the two wireless in-ear audio devices 7 covered in the two noose units 1 are both detached from the user's ears, that is, when the user no longer uses the two wireless in-ear audio devices 7, the connecting line 2 is first wrapped around the user's arm, and the length of the connecting line 2 is sufficient to wrap around the user's arm once or multiple times, so that the length of the connecting line 2 is longer than the circumference of the user's arm. Finally, the two magnetic elements 5 are exposed, and the two magnetic elements 5 are attracted to each other and joined to form the surrounding space 24. At this time, the user's arm is accommodated in the surrounding space 24 formed by the surrounding of the connecting line 2, and the anti-loss rope and the two wireless in-ear audio devices 7 connected thereto are hung around the user's arm, thereby preventing the two wireless in-ear audio devices 7 from being lost. Of course, in this embodiment, if the connecting line 2 is not wrapped around the user's arm, the length of the connecting line 2 is sufficient to insert the two wireless in-ear audio devices 7 into the user's ears at the same time.

[0079] Similarly, the two noose units 1 of the loss prevention rope according to the seventh embodiment can be installed on the two temples 93 of the eyeglass frame 9 according to the first embodiment in a one-to-one correspondence. Specifically, the two accommodation spaces 13 of the loss prevention rope according to the seventh embodiment also accommodate the two temples 93 of the eyeglass frame 9 in a one-to-one correspondence, and the connection line 2 is wound around the back of the user's neck and connected to the user's neck, thereby preventing the eyeglass frame 9 from being directly lost when the user removes the eyeglass frame 9.

[0080] In other embodiments, the two magnetic elements 5 may be connected to the connecting wire 2 according to the second, third, and fourth embodiments, and the connection method between the magnetic elements 5 and the connecting wire 2 is the same as that of the seventh embodiment, so the description thereof will not be repeated here.

[0081] <Eighth Example> The configuration of the eighth embodiment of the present invention is shown in Figures 34 to 39. The difference between the loss prevention rope of the eighth embodiment of the present embodiment and the loss prevention rope of the first embodiment is that the loss prevention rope further includes two elastic sleeves 6 and two magnetic elements 5. The two elastic sleeves 6 are covered on the connecting line 2 and are spaced apart along the length of the connecting line 2, and each of the elastic sleeves 6 has a through groove 61 for passing the connecting line 2 through and a storage tank 62 for storing the magnetic element 5. In this embodiment, the through groove 61 and the storage tank 62 are connected to each other in a direction perpendicular to the length of the connecting line 2, and jointly form a straight groove. The size of the straight groove is larger than the size of the connecting line 2, and the elastic sleeve 6 slides along the length of the connecting line 2. In a situation where the connecting wire 2 passes through the corresponding through grooves 61 of the two elastic sleeves 6, one of the magnetic elements 5 blocks the corresponding storage tank 62 of one of the elastic sleeves 6, the other magnetic element 5 blocks the corresponding storage tank 62 of the other elastic sleeve 6, the two magnetic elements 5 press the corresponding elastic sleeves 6 and the connecting wire 2, the two magnetic elements 5 are respectively clamped between the corresponding elastic sleeves 6 and the connecting wire 2, the two magnetic elements 5 are connected to the connecting wire 2, the elastic sleeve 6 is restricted to move along the extension direction of the length of the connecting wire 2, and the elastic sleeve 6 is positioned on the connecting wire 2. Specifically, in this embodiment, the two elastic sleeves 6 are positioned at positions adjacent to both ends of the connecting wire 2, that is, positioned at positions adjacent to the two noose units 1. The two magnetic elements 5 can be joined by being attracted to each other, and the portion of the connecting wire 2 located between the two elastic sleeves 6 is surrounded to form an enclosed space 24. In this embodiment, the magnetic element 5 is installed as a solid cylinder. In this embodiment, the two magnetic elements 5 may be magnets, or one may be a magnet and the other may be made of a material that is attracted to a magnet. The remaining structure is the same as that of the first embodiment of the present invention, and therefore the description thereof will not be repeated here.

[0082] In another embodiment, the through groove 61 of the elastic sleeve 6 may not be connected to the storage tank 62 in the direction perpendicular to the length direction of the connecting wire 2. When the connecting wire 2 is accommodated in the through groove 61 and the magnetic element 5 is accommodated in the storage tank 62, the part of the elastic sleeve 6 located between the magnetic element 5 and the connecting wire 2 is elastic, so that the magnetic element 5 blocks and compresses the elastic sleeve 6 to deform it, and the magnetic element 5 indirectly compresses the connecting wire 2, and the magnetic element 5 and the elastic sleeve 6 are positioned at a specific position of the connecting wire 2 by bidirectional compression of the connecting wire 2 and the elastic sleeve 6.

[0083] As shown in FIG. 38, in the eighth embodiment, when the two wireless in-ear audio devices 7 covered in the two noose units 1 are both removed from the user's ears, that is, when the user no longer uses the two wireless in-ear audio devices 7, the connecting wire 2 is first wrapped around the back of the user's neck, and the two wireless in-ear audio devices 7 are hung on the user's chest, and the two magnetic elements 5 are attracted to each other, surrounding the portion of the connecting wire 2 located between the two protrusion limiting parts 25, forming the surrounding space 24, and the user's neck is accommodated snugly in the surrounding space 24. Since the length of the connecting wire 2 is longer than the circumference of the user's neck, the two wireless in-ear audio devices 7 connected to the connecting wire 2 are prevented from being lost by hanging the connecting wire 2 around the user's neck. At this time, the two wireless in-ear audio devices 7 may be hung on the user's chest or back according to the user's needs.

[0084] 39, in the eighth embodiment, when the two wireless in-ear audio devices 7 covered in the two noose units are detached from the user's ears, that is, when the user no longer uses the two wireless in-ear audio devices 7, the connecting wire 2 is first wrapped around the user's arm, and the length of the connecting wire 2 is sufficient to wrap around the user's arm once or multiple times, and the length of the connecting wire 2 is longer than the circumference of the user's arm, so that the two elastic sleeves 6 and the corresponding two magnetic elements 5 are finally exposed, and the two magnetic elements 5 are attracted to each other and joined to form the surrounding space 24. At this time, the user's arm is accommodated in the surrounding space 24 formed by the surrounding of the connecting wire 2, and the anti-loss rope and the two wireless in-ear audio devices 7 connected thereto are hung on the user's arm, thereby preventing the two wireless in-ear audio devices 7 from being lost. Of course, in this embodiment, when the connecting line 2 is not wrapped around the user's arm, the length of the connecting line 2 is sufficient for inserting the two wireless in-ear audio devices 7 into the user's ears simultaneously.

[0085] Similarly, in the eighth embodiment, the two noose units 1 of the loss prevention rope can be installed on the two temples 93 of the eyeglass frame 9 according to the first embodiment in a one-to-one correspondence. Specifically, the two accommodation spaces 13 of the loss prevention rope according to the eighth embodiment can accommodate the two temples 93 of the eyeglass frame 9 in a one-to-one correspondence, and the connection line 2 is wound around the back of the user's neck and connected to the user's neck, thereby preventing the eyeglass frame 9 from being directly lost when the user removes the eyeglass frame 9.

[0086] In other embodiments, the two elastic sleeves 6 and the two magnetic elements 5 are connected to the connecting wire 2 of the second, third and fourth embodiments, and the connection method between the magnetic element 5 and the connecting wire 2 is the same as that of the eighth embodiment, so the description thereof will not be repeated here.

[0087] The anti-lost rope according to the present invention has the following beneficial effects:

[0088] 1) The anti-loss rope is provided with the flexible sleeve 11 that is wrapped around the outside of the elastic wire 12, and the flexible sleeve 11 is in direct contact with the ear handle 72 (first object) or the temple 93 (first object) of the eyeglass frame 9 outside the wireless in-ear audio device 7, and is connected to the connection line 2 of another wireless in-ear audio device 7 (second object) or another temple 93 (second object) of the eyeglass frame 9 or the clamping part 8 (second object), and is connected to the exposed part 122 of the elastic wire 12. Since the elastic wire 12 has elasticity, the noose unit 1 is wrapped around the outside of the ear handle 72 or the temple 93 that have different circumferential lengths, improving the adaptability of the anti-loss rope. When the flexible sleeve 11 is attached to the surface of the ear handle 72 or the temple 93, and the elastic wire 12 and the flexible sleeve 11 outside it are covered from the outside to the inside of the ear handle 72 or the temple 93, the flexible sleeve 11 rotates on the outer surface of the ear handle 72 or the outer surface of the temple 93, the flexible sleeve 11 rotates around the elastic wire 12, and the rotation of the flexible sleeve 11 does not directly link the elastic wire 12 installed separately therefrom to rotate the same number of times or more, thereby reducing the degree to which the connecting line 2 connected to the elastic wire 12 is wound in the receiving space 13. Since the flexible sleeve 11 is soft, it does not damage the ear handle 72 or the temple 93 or the surfaces that come into contact with them when the flexible sleeve 11 rotates.

[0089] 2) The connecting wire 2 has elasticity, and generates a cushioning effect when the wireless in-ear audio device 7 falls off the user's ear, preventing the user's ear from being damaged even if the wireless in-ear audio device 7 is pulled strongly, thereby reducing the pain caused by the device. It also prevents the wireless in-ear audio device 7 from falling directly onto other objects due to gravity and being damaged. Alternatively, it generates a cushioning effect when the eyeglass frame 9 falls off the user's face, preventing the user's neck from being damaged when the eyeglass frame 9 is pulled strongly, thereby reducing the pain caused by the device. It also prevents the eyeglass frame 9 from falling directly onto other objects due to gravity and being damaged.

[0090] 3) The through hole 112 has a rectangular cross section perpendicular to the extension direction of the length of the flexible sleeve 11, and the elastic wire 12 has a circular cross section perpendicular to the extension direction of the length of the elastic wire 12. The rectangular cross section of the elastic wire 12 contacts the outer surface of the ear handle 72 or the outer surface of the temple 93 in a flat surface, so that the elastic wire 12 with a rectangular cross section is less likely to rotate following the flexible sleeve 11 in which the circular through hole 112 is provided.

[0091] 4) The length of the connecting line 2 is sufficient to wrap around the back of the user's neck, so that even if the two wireless in-ear audio devices 7 fall off from the user's ears, the two wireless in-ear audio devices 7 will not be directly lost because the connecting line 2 is hanging around the user's neck. Also, when the eyeglasses frame 9 is removed from the user's face, the eyeglasses frame 9 will not be directly lost because the connecting line 2 is hanging around the user's neck.

[0092] 5) The second object is the clamping part 8, which is used to be clamped to clothing worn by the user or to the user's earlobe, etc. Even if the wireless in-ear audio device 7 falls off the user's ear, the wireless in-ear audio device 7, which is indirectly connected to the clamping part 8, will not be directly lost because the clamping part 8 is clamped to the user's clothing or the user's earlobe.

[0093] 6) The thicknesses T2 and T3 between the inner end 31 and the outer end 32 of the collar 3 are not thicker than the linear distances D1 and D2 that the outer surface of the flexible sleeve 11 exceeds the outer surface of any one of the exposed portions 122, and the collar 3 is engaged between the outer surface of the exposed portion 122 and the outer surface of the ear handle 72 or between the outer surface of the exposed portion 122 and the outer surface of the ear handle 72, and easily rotates.

[0094] 7) The connecting wire 2 is covered by the collar 3, and the noose unit 1 is connected to the connecting wire 2 via the collar 3. Therefore, when the elastic wire 12 of the noose unit 1 rotates, the connecting wire 2, which is installed separately from the elastic wire 12, becomes difficult to rotate or does not rotate following the elastic wire 12, and further interlocks with the collar 3 to rotate. The connecting wire 2 is held at a specific position in the circumferential extension direction of the collar 3 during the rotation of the collar 3 due to the action of gravity. In addition, the connecting wire 2 moves along the circumferential extension direction of the collar 3, which further prevents the connecting wire 2 from becoming entangled.

[0095] 8) The collar 3 is made of a hard non-metallic material and has a low coefficient of friction. Specifically, the material of the collar 3 is ceramic or polytetrafluoroethylene, and the outer surface of the collar 3 is smooth. Since the frictional force between the collar 3 and the exposed portion 122 is very small, a slip phenomenon occurs, and the collar 3 is difficult to or does not rotate even when the exposed portion 122 rotates. In addition, since the outer surface of the collar 3 is smooth, the collar 3 is prevented from rubbing against the outer surface of the ear handle 72 or the outer surface of the temple 93 when the collar 3 rotates around the exposed portion 122.

[0096] 9) The magnetic elements 14 are installed in the corresponding flexible sleeves 11 and are located outside the corresponding through holes 112, so that the two magnetic elements 14 of the two noos units 1 can be attracted to each other and joined together, and at this time, the winding space 21 is formed by the surrounding of the connecting wire 2. The user stores his / her neck or arm in the winding space 21 and wraps the connecting wire 2 around the user's neck or arm, so that when the user no longer uses the two wireless in-ear audio devices 7, the two wireless in-ear audio devices 7 covered in the two noos units 1 are hung around the user's neck or arm, so they will not be lost and are convenient to carry. In addition, there is no need to separately install a storage member for storing the two wireless in-ear audio devices 7.

[0097] 10) A part of the connecting line 2 is accommodated in the positioning portion 41 of the converging member 4, and another part of the connecting line 2 enters the engagement space 421 of the converging member 4 through the notch portion 422 of the converging member 4, thereby forming the surrounding space 24 for inserting the user's neck or arm in the connecting line 2, which makes the operation convenient. In addition, the converging member 4 can be slid along the extension direction of the length of the connecting line 2 to adjust the size of the surrounding space 24 to fit different users' arms and necks.

[0098] 11) The two magnetic elements 5 are installed at an interval on the connecting line 2 along the extension direction of the length of the connecting line 2, and the two magnetic elements 5 are attracted to each other and joined together, at which point the connecting line 2 surrounds and forms the surrounding space 24. The user places his / her neck or arm in the surrounding space 24 and wraps the connecting line 2 around the user's neck or arm, so that when the user no longer uses the two wireless in-ear audio devices 7, the two wireless in-ear audio devices 7 connected to the connecting line 2 are hung around the user's neck or arm and will not get lost, making them convenient to carry. In addition, there is no need to separately install a housing member for housing the two wireless in-ear audio devices 7.

[0099] 12) The protrusion limiting portion 25 formed by connecting the connection wires 2 limits the movement of the magnetic element 5 to between the two protrusion limiting portions 25 along the extension direction of the length of the connection wires 2. Since there is no need to install a separate member to limit the displacement of the magnetic element 5, the structure is simplified.

[0100] 13) The magnetic element 5 seals the gap between the elastic sleeve 6 and the connecting wire 2, so that the elastic sleeve 6 and the connecting wire 2 press against the magnetic element 5, respectively, and the magnetic element 5 and the elastic sleeve 6 are installed at specific positions on the connecting wire 2, making the installation method simple and the replacement of the magnetic element 5 convenient.

[0101] The present invention is not limited to the above-described embodiments, and various modifications are possible within the scope of the claims. Embodiments obtained by appropriately combining the technical means disclosed in different embodiments are also included in the technical scope of the present invention. [Explanation of symbols]
