BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to an anti-loss rope, and more particularly, to an anti-loss rope for a wireless in-ear audio device or a glasses frame.
2. Description of the Related Art
A wireless Bluetooth earphone usually includes an earplug portion plugged into an ear of a user and a leg portion exposed outside the ear of the user. A current anti-loss rope is made of solely of an elastic rope. The anti-loss rope includes two enclosed accommodating loops respectively formed by enclosing both ends of the elastic rope, and a middle portion located between the two accommodating loops and integrally connected with the two accommodating loops. Each of the accommodating loops is for accommodating the leg portion of the wireless Bluetooth earphone. In order to connect the accommodating loop to the leg portion, it is necessary to encircle the leg portion from bottom to top by the accommodating loop.
However, before encircling the leg portion by the accommodating loop, the elastic rope corresponding to the accommodating loop is flexed due to the flexibility of the elastic rope. For example, the elastic rope may be flexed into the FIG. 8, such that the leg portion may fail to be inserted into the accommodating loop. Or, the accommodating loop formed may be rather small due to the elasticity of the elastic rope, such that it may be difficult for the leg portion to be inserted into the accommodating loop. In both of the cases above, the user is required to manually stretch the accommodating loop to a size adapted to the leg portion in order to readily insert the leg portion, resulting in operation difficulties.
Similarly, the two accommodating loops of the anti-loss rope may also be applied to accommodate two temples of a glasses frame. Thus, it is known that, the elastic rope corresponding to the two accommodating loops formed are also flexed before the two accommodating loops accommodate the two temples, similarly leading to the issue that it may be difficult to insert the glasses frame into the accommodating loops.
Therefore, there is a need for a novel anti-loss rope to overcome the issue above.

Referring to FIG. 1, FIG. 2, FIG. 10 and FIG. 11 showing an anti-loss rope of the present invention, the anti-loss rope connects a first target object to a second target objects. In this embodiment, the anti-loss rope can be used to connect to two wireless in-ear audio devices 5. By connecting with a neck of a user or a wrist of a user via the anti-loss rope, the two wireless in-ear audio devices 5 are prevented from directly being lost when not in use. At this point, both of the first target object and the second target object are the wireless in-ear audio device 5.
As shown in FIG. 12 and FIG. 13, the anti-loss rope of the present invention can be further used to be connected to a glasses frame 6. By connecting with the neck of the user via the anti-loss rope, the glasses frame 6 is prevented from being directly lost when not in use.
In other embodiments, the anti-loss rope may be connected to only one of the wireless in-ear audio device 5, and the other end of the anti-loss rope is connected to clothes, an earlobe or a lobule of the user by a fastener, so as to prevent the wireless in-ear audio device 5 from directly being lost in case it falls off from the ear of the user. At this point, the first target object is the wireless in-ear audio device 5 and the second target object is the fastener.
As shown in FIG. 2, FIG. 10 and FIG. 11, the wireless in-ear audio device 5 includes an earplug portion 51 plugged into the ear of the user and an earphone leg 52 exposed outside the ear of the user. The earphone leg 52 is for connecting with the anti-loss rope. In this embodiment, the earphone leg 52 is configured to be a cylinder for connecting with the anti-loss rope. In other embodiments, the earphone leg 52 is configured to be a cuboid.
As shown in FIG. 12 and FIG. 13, the glasses frame 6 includes two rims 61 spaced and arranged in opposite, a bridge 62 located between the rims 62, and two temples 63 respectively located on outer sides of the two rims 61. The bridge 62 connects the two rims 61, the two temples 63 are correspondingly connected to the two temples 61 in one-on-one correspondence, and the two temples 63 are arranged in opposite.

As shown in FIG. 1, FIG. 2, FIG. 10 and FIG. 11, the anti-loss rope includes two noose units 1, a longitudinal connecting line 2, two collars 3 that directly connect the noose units 1 with the connecting line 2, and two magnetic elements 4. Two ends of the connecting line 2 are for connecting with the two noose units 1, and more specifically, the two ends of the connecting line 2 are for directly connecting with the two collars 3, respectively, and the two collars 3 are then directly connected with the two noose units 1 in one-on-one correspondence, so as to indirectly connect together the connecting line 2 with the two noose units 1. The two noose units 1 respectively encircle the outside of the earphone legs 52 of the wireless in-ear audio device 5, that is, each of the two ends of the connecting line 2 is indirectly connected with the corresponding wireless in-ear audio device 5 via the noose unit 1. The two magnetic elements 4 are respectively disposed at the two noose units 1, and are attractive to each other so as be joined together. When the two magnetic elements 4 are attracted to each other and joined together, the connecting line 2 surround to form a winding space 21. In this embodiment, the two magnetic elements 4 disposed on the two noose units 1 may both be magnets, or one may be a magnet and the other made be made of a magnetically attractive material.
As shown in FIG. 12 and FIG. 13, the two noose units 1 respectively encircle the two temples 63 of the glasses frame 6, that is, each of the two ends of the connecting line 2 are indirectly connected with the corresponding temple 63 via the noose unit 1. It is known at this point that the first target object and the second target object are the two temples 63.
In other embodiments, the anti-loss rope includes one of the noose unit 1, the fastener, and a connecting wire 2 connected with the noose unit 1 and the fastener. One end of the connecting line 2 is connected with one of the wireless in-ear audio device 5 via the noose unit 1, and the other end of the connecting line 2 is indirectly connected to the clothes, earlobe or lobule of the user serving as the second target object via the fastener.
As shown in FIG. 1, FIG. 3 and FIG. 4, each of the noose units 1 includes a flexible sleeve 11, and an elastic line 12 passing through the flexible sleeve 11 along the lengthwise extension direction of the flexible sleeve 11.
As shown in FIG. 3, FIG. 4 and FIG. 9, the flexible sleeve 11 includes a tube portion 11A, and a blocking portion 11B formed as protruding outward from the tube portion 11A. The tube portion 11A includes two end portions 111 located on two ends of the lengthwise extension direction of the tube portion 11A, and a through hole 112 located in the tube portion 11A and extending along the lengthwise extension direction of the tube portion 11A. The through hole 112 is for the elastic line 12 to pass through. The blocking portion 11B is located on outside of the through hole 112, and is provided with an accommodating space 113 for accommodating the magnetic element 4. The accommodating space 113 is spaced from the through hole 112, that is, the two are not in communication, and the accommodating space 113 passes through the blocking portion 11B for the magnetic element 4 to be installed to the accommodating space 113 from outside to inside. Moreover, the user may take out the magnetic element 4 via the accommodating space 113 for replacement.
In other embodiments, the two magnetic elements 4 may be spaced at the connecting line 2 along the lengthwise extension direction of the connecting line 2.
As shown in FIG. 1, FIG. 3 and FIG. 4, the flexible sleeve 11 has elasticity, and is stretchable to a certain extent along the lengthwise extension direction thereof, and the elasticity thereof is less than the elasticity of the elastic line 12. It should be noted that, the flexible sleeve 11 also has a certain extent of elasticity in a cross section direction perpendicular to the lengthwise direction thereof.
In other embodiments, it is possible for the flexible sleeve 11 to be without elasticity.
As shown in FIG. 3, FIG. 4 and FIG. 8, the length of the flexible sleeve 11 is not less than one half of the periphery of the earphone leg 52. In this embodiment, the length of the flexible sleeve 11 is greater than one half of the earphone leg 52, and more specifically, the length of the flexible sleeve 11 is 20 mm to 22 mm, and the length is more adaptive to the earphone leg 52 of the wireless in-ear audio device 5 commercially available.
As shown in FIG. 12 and FIG. 13, the length of the flexible sleeve 11 is not less than one half of the periphery of the temple 63. In this embodiment, the length of the flexible sleeve 11 is greater than one half of the periphery of the temple 63.
As shown in FIG. 1, FIG. 3 and FIG. 4, the length of the elastic line 12 is greater than the length of the flexible sleeve 11, and the flexible sleeve 11 is capable of displacing along the lengthwise extension direction of the elastic line 12. The elastic line 12 has an accommodated section 121 accommodated in the through hole 112, and an exposed section 122 connected to two ends of the accommodated section 121; that is, the exposed section 122 is exposed outside the flexible sleeve 11, and the exposed section 122 and the accommodated section 121 are head-tail connected to form an enclosed coil structure. In other words, the elastic line 12 is the coil structure encircled and formed by the exposed section 122 and the accommodated section 121. The part of the elastic line 12 accommodated in the through hole 112 is defined as the accommodated section 121, and the part of the elastic line 12 protruding out of the flexible sleeve 11 is defined as the exposed section 122. With the coil structure encircled and formed by the exposed section 122 and the accommodated section 121, the flexible sleeve 11 sleeving the accommodated section 121 and the exposed section 122 enclose to form an accommodating space 13. The accommodating space 13 is for accommodating the earphone leg 52 so as to encircle the noose unit 1 on the earphone leg 52, and at the same time the blocking portion 11B and the magnetic element 4 accommodated in the blocking portion 11B are located on outside of the accommodating space 13.
As shown in FIG. 12 and FIG. 13, the two temples 63 are for connecting with the anti-loss rope, and more specifically, the two temples 63 are accommodated in the two accommodating spaces 13 formed by the two noose units 1 in one-on-one correspondence, such that the two noose units 1 also encircle the two temples 63. At the same time, the blocking portion 11B and the magnetic element 4 accommodated in the blocking portion 11B are located on the outside of the accommodating space 13.
As shown in FIG. 3, FIG. 4 and FIG. 6, the elastic line 12 is a coil structure formed by an resilience line having two free ends and by fixing the free ends to each other. The two free ends are fixed with each other to form a connecting portion 123, which is located at the exposed section 122. In this embodiment, the connecting portion 123 is a knot.
In other embodiments, the connecting portion 123 is located at the accommodated section 121, that is, accommodated in the through hole 112 of the tube portion 11A.
As shown in FIG. 1, FIG. 3 and FIG. 4, the elastic line 12 is a rubber band. The rubber band is made of double-wrapped high-quality double-strand fiber yarn (polyester yarn or nylon yarn, also known as Tedron™ yarn or nylon yarn).
As shown in FIG. 6, the tube portion 11A is configured to be a tube having a straight line shape when the flexible sleeve 11 is not passed through by the elastic line 12. When the elastic line 12 passes through the through hole 112 and the coil structure is formed, the tube portion 11A is correspondingly deformed according to the lengthwise extension direction of the elastic line 12, such that the tube portion 11A curves into a C shape from the straight line shape.
As shown in FIG. 3, FIG. 4, FIG. 8 and FIG. 13, the flexible sleeve 11 is for surrounding the earphone leg 52 or the temple 63 and directly contacts a surface of the earphone leg 52 or the temple 63, and the flexibility of the flexible sleeve 11 prevents the flexible sleeve 11 from damaging the earphone leg 52 or the temple 63 or the surfaces contacting therewith. The elastic line 12 passes through the flexible sleeve 11 to cause the flexible sleeve 11 to correspondingly deform according to the lengthwise extension direction of the elastic line 12. Due to the presence of the elasticity of the elastic line 12, the flexible sleeve 11 is closely attached to the surface of the earphone leg 52 or the temple 63. Similarly, the elastic line 12 is configured to also surround the earphone leg 52 or the temple 63. With the elasticity of the elastic line 12, the earphone leg 52 or the temple 63 having different circumferences can be encircled by the noose unit 1, so as to enhance the adaptivity of anti-loss rope. When the earphone leg 52 or the temple 63 is not inserted into the accommodating space 13, the accommodating space 13 is in an irregular arrangement. When the earphone leg 52 or the temple 63 is inserted into the accommodating space 13, the accommodating space 13 utilizes the elasticity of the elastic line 12 to transform from an original irregular shape to a shape that adapts to the outer peripheral surface of the earphone leg 52 or the temple 63, so as to encircle the wireless in-ear audio device 5 or the temple 63 by the noose unit 1.
As shown in FIG. 4, FIG. 6, FIG. 7 and FIG. 13, the shape of a cross section of the through hole 112 perpendicular to the lengthwise extension direction of the tube portion 11A is different from the shape of the elastic line 12 in the same cross section perpendicular to the lengthwise extension direction of the elastic line 12. More specifically, the shape of the cross section of the through hole 112 perpendicular to the lengthwise extension direction of the tube portion 11A is circular, and the shape of the cross section of the through hole 112 along the lengthwise extension direction of the tube portion 11A is kept consistent, that is, the through hole 112 is a circular through hole having a constant diameter along the lengthwise extension direction of the tube portion 11A. The diameter of the through hole 112 is 1 mm. The shape of the cross section of the elastic line 12 perpendicular to the lengthwise extension direction of the elastic line 12 is quadrilateral, and more specifically, rectangular, and the shape of the cross section of the elastic line 12 along the lengthwise extension direction of the elastic line 12 is also kept consistent. More specifically, the lengthwise side of the rectangular cross section of the elastic line 12 is 0.9 mm, and the widthwise side is 0.6 mm. In this embodiment, since the rectangular cross section of the elastic line 12 is in plane contact with the outer surface of the earphone leg 52 or the outer surface of the temple 63, the elastic line 12 having a rectangular cross section is even more unlikely to roll along with the flexible sleeve 11 provided with the circular through hole 112.
As shown in FIG. 7, the tube portion 11A is configured as a ring in the cross section perpendicular to the lengthwise extension direction thereof, and the outer diameter of the tube portion 11A is not greater than 2 mm.
As shown in FIG. 1, FIG. 3 and FIG. 4, each of the collars 3 includes an inner ring edge 31 and an outer ring edge 32. Each of the collar 3 sleeves around the exposed section 122 of the corresponding noose unit 1, and is rotatable around the corresponding exposed section 122, that is, the exposed section 122 passes through the collar 3 and can be directly connected to the collar 3. A thickness T2 between the inner ring edge 31 and the outer ring edge 32 is not greater than a linear distance D1 by which an outer peripheral surface of the flexible sleeve 11 exceeds an outer peripheral surface of the exposed section 122. Moreover, the thickness T2 between the inner ring edge 31 and the outer ring edge 32 is less than a thickness T1 of the tube wall of the tube portion 11A, such that the collar 3 can be fittingly engaged between the outer peripheral surface of the exposed section 122 and the outer surface of the earphone leg 52, or be rotatable and movable between the outer peripheral surface of the exposed section 122 and the outer surface of the earphone leg 52.
As shown in FIG. 5, in other embodiments, a thickness T3 between the inner ring edge 31 and the outer ring edge 32 is less than a linear distance D2 by which the outer peripheral surface of the flexible sleeve 11 exceeds the outer peripheral surface of the exposed section 122, such that the collar 3 is rotatable and movable between the outer peripheral surface of the exposed section 122 and the outer surface of the earphone leg 52.
As shown in FIG. 1, FIG. 3, FIG. 4 and FIG. 13, the collar 3 is made of a hard non-metal material and has a low coefficient of friction. More specifically, the material of the collar 3 is ceramic or hard Teflon™ in a way that the outer surface of the collar 3 is smooth, and sliding occurs due to an extremely small frictional force between the collar 3 and the exposed section 122, such that the exposed section 122 is unlikely to roll and further does not drive the collar 3 to roll. At the same time, with the smooth outer surface of the collar 3, even if the collar 3 rotates around the exposed section 122, the collar 3 is still prevented from scratching the outer surface of the earphone leg 52 or the outer surface of the temple 63.
As shown in FIG. 1, FIG. 2 and FIG. 3, each of two ends of the connecting line 2 passes through the corresponding collar 3, and is arranged around a part of the circumferential direction of the corresponding collar 3, so as to be directly connected with the corresponding collar 3. That is, the two ends of the connecting line 2 are placed around the two collars 3 in one-on-one correspondence, and the connecting line 2 is rotatable around the collars 3. In other words, the collar 3 is rotatable relative to the connecting line 2, and the connecting line 2 is movable along the circumferential extension direction of the collar 3. Since both of the collars 3 are connected to the exposed sections 122 of the corresponding noose units 1, it is known that each of the two ends of the connecting line 2 is indirectly connected with the exposed section 122 of the noose unit 1 via the corresponding collar 3.
In other embodiments, the two ends of the connecting line 2 may be directly connected with the corresponding exposed sections 122 of the two noose units 1.
In other embodiments, the two ends of the connecting line 2 may be directly connected with the corresponding flexible sleeves 11 of the two noose units 1.
As shown in FIG. 1 and FIG. 2, in this embodiment, the connecting line 2 has elasticity, so as to provide buffering when the wireless in-ear audio device 5 falls off from the ear of the user, and to also prevent damage of the ear of the user when the wireless in-ear audio device 5 is pulled by force, hence reducing the sense of pain brought thereby as well as preventing damage of the wireless in-ear audio device 5 when it directly falls on other objects due to gravity.
As shown in FIG. 12, the connecting line 2 has elasticity, so as to provide buffering when the glasses frame 6 falls off from the face of the user, and to also prevent hurting of the face of the user when the glasses frame 6 is pulled by force, hence reducing the sense of pain brought thereby as well as preventing damage of the glasses frame 6 when it falls directly on other objects due to gravity.
As shown in FIG. 2, FIG. 3, FIG. 9 and FIG. 13, the flexible sleeve 11 is closely attached on the outer surface of the earphone leg 52 or the outer surface of the temple 63 due to the elasticity of the elastic line 12, such that the flexible sleeve 11 sleeves the earphone leg 52 or the temple 63 from outside to inside, and the flexible sleeve 11 rolls around the lengthwise extension direction thereof. However, because the flexible sleeve 11 and the elastic line 12 are provided separately, the flexible sleeve 11 is capable of rolling around the elastic line 12, while the elastic line 12 is unlikely to roll along with the flexible sleeve 11 sleeving on the outside. Since the elastic line 12 is connected to the connecting line 2 via the collar 3, the connecting line 2 that is provided separately from the elastic line 12 is unlikely to or does not at all roll along with the elastic line 12 when the elastic 12 rolls, or the collar 3 is driven to roll at most. Due to gravity, the connecting line 2 is kept on a specific position in the circumferential extension direction of the collar 3 during the rolling of the collar 3, and the connecting line 2 is movable along the circumferential extension direction of the collar 3 to further prevent twisting or knotting of the connecting line 2 or even from entering the accommodating space 13. Moreover, in this embodiment, the sleeve 3 is for the elastic line 12 and the connecting line 2 to pass through, that is, both of the corresponding part of the elastic line 12 and the corresponding part of the connecting line 2 are located within the inner ring edge 31 of the collar 3, and a gap is preserved between the elastic line 12 and the connecting line 2, so as to prevent the elastic line 12 and the connecting line 2 from twisting with each other. Meanwhile, when the flexible sleeve 11 rolls around the elastic line 12, the blocking portion 11B abuts against the outer surface of the earphone leg 52 or the outer surface of the temple 63 and further prevents the flexible sleeve 11 from rolling excessively. At the same time, the blocking portion 11B is kept in the state of abutting against the outer surface of the earphone leg 52 or the outer surface of the temple 63, and slides on the outer surface of the earphone leg 52 or the outer surface of the temple 63, so as to prevent rolling of the elastic line 12, further prevent rolling of the collar 3 connected to the elastic line 12, and yet further prevent rolling and knotting of the connecting line 2 connected to the collar 3 or even from entering the accommodating space 13.
In other embodiments, the connecting portion 123 is accommodated in the through hole 112 of the tube portion 11A, preventing the connecting portion 123 from interfering with the collar 3, further preventing non-rotatability of the collar 3, or preventing the connecting portion 123 of the elastic line 12 from interfering and hence from twisting with the connecting line 2.
As shown in FIG. 1 and FIG. 2, when the two earplug portions 51 of the two wireless in-ear audio devices 5 are plugged into both ears of the user, the length of the connecting line 2 is sufficient to go around to the back of the neck of the user. At this point, if the both of the wireless in-ear audio devices 5 fall off from the ears of the user, the two wireless in-ear audio devices 5 do not become directly lost since the connecting line 2 is hung around the neck of the user.
As shown in FIG. 12, when the user wears the glasses frame 6, the length of the connecting line 2 at this point is sufficient to go around to the back of the neck of the user. If the user takes the glasses frame 6 off from the ears and the nose bridge of the user, the glasses frame 6 does not become directly lost since the connecting line 2 is hung around the neck of the user.
As shown in FIG. 1, FIG. 2 and FIG. 10, when both of the wireless in-ear audio devices 5 encircled by the noose units 1 are disengaged from the ears of the user, that is, when the user is not currently using the two wireless in-ear audio devices 5, the connecting line 2 is put around to the back of the neck of the user, the two wireless in-ear audio devices 5 are hung in front of the chest of the user, and the two magnetic elements 4 in the two noose units 1 are attracted to each other and joined together to enclose and form the winding space 21. At this point, the neck of the user is exactly accommodated in the winding space 21. It is known that the length of the connecting line 2 is greater than the neck circumference of the user, so as to hang the connecting line 2 on the neck of the user, further preventing losing of the two wireless in-ear audio devices 5 connected to the connecting line 2. At this point, the two wireless in-ear audio devices 5 can be hung in front of the chest or on the back of the user according to user needs.
As shown in FIG. 1, FIG. 2 and FIG. 11, when the two wireless in-ear audio devices 5 encircled in the two noose units 1 are disengaged from the ears of the user, that is, when the user is not currently using the two wireless in-ear audio devices 5, the connecting line 2 may first wind around the wrist of the user. The length of the connecting line 2 allows the connecting line 2 to be wound around the wrist of the user by one round or more rounds, and so it is known that the length of the connecting line 2 is greater than the wrist circumference of the wrist of the user. Lastly, the two flexible sleeves 11 of the two noose units 1 are then exposed, and the two magnetic elements 4 are then attracted to each other and joined together to form the winding space 21. At this point, the wrist of the user is accommodated in the winding space 21 enclosed and formed by the connecting line 2, so as to hang the two wireless in-ear audio devices 5 at the wrist of the user, preventing losing of the two wireless in-ear audio devices 5. It should be noted that, in this embodiment, when the connecting line 2 is not wound around the wrist of the user, the length of the connecting line 2 is sufficient to allow both of the two wireless in-ear audio devices 5 to be concurrently plugged into the ears of the user.
The anti-loss rope of the present invention provides the following benefits.
1) The anti-loss rope of the present invention is provided with the flexible sleeve 11 sleeving around the elastic line 12, and the flexible sleeve 11 and the exposed section 122 of the elastic line 12 enclose and form the accommodating space 13. Thus, curving of the accommodating space 13 caused by curving of the elastic line 12 is prevented, or decreasing of the accommodating space 13 due to the elasticity of the elastic line 12 is prevented, hence better maintaining the size of the accommodating space 13 so as to adapt to the earphone leg 52 or the temple 63 to better readily insert the earphone leg 52 or the temple 63. Moreover, the flexibility of the flexible sleeve 11 prevents the flexible sleeve 11 from damaging the earphone leg 52 or the temple 63 or the surface in contact therewith, and the elasticity of the elastic line 12 is capable of encircling the earphone leg 52 or the temple 63 having different circumferences by the noose unit 1 so as to enhance the adaptivity of the anti-loss rope.
2) The flexible sleeve 11 is closely attached on the surface of the earphone leg 52 or the temple 63. When the elastic line 12 and the flexible sleeve 11 on the outside sleeve the earphone leg 52 or the temple 63 from bottom to top, the flexible sleeve 11 rolls at the outer surface of the earphone leg 52 or the temple 63, and the flexible sleeve 11 rolls around the elastic line 12. However, the rolling of the flexible sleeve 11 does not directly drive the elastic line 12 provided separately therefrom to roll as many or even more rounds. Even if rolling of the elastic line 12 of the noose unit 1 occurs, the connecting line 2 connected to the elastic line 12 via the collar 3 is also unlikely to roll along with the elastic line 12, but further may drive the collar 3 to roll instead. Due to gravity, the connecting line 12 is kept on a specific position in the circumferential extension direction of the collar 3 during the process of rolling of the collar 3. Moreover, the connecting line 2 is movable along the circumferential extension direction of the collar 3, further preventing twisting and knotting of the connecting line 2.
3) The connecting line 2 has elasticity, so as to provide buffering when the wireless in-ear audio device 5 falls off from the ear of the user, and to also prevent damage of the ear of the user when the wireless in-ear audio device 5 is pulled by force, hence reducing the sense of pain brought thereby as well as preventing damage of the wireless in-ear audio device 5 when it directly falls on other objects due to gravity; or to provide buffering when the glasses frame 6 falls off from the face of the user, and to also prevent hurting of the face of the user when the glasses frame 6 is pulled by force, hence reducing the sense of pain brought thereby as well as preventing damage of the glasses frame 6 when it falls directly on other objects due to gravity.
4) The shape of the cross section of the through hole 112 perpendicular to the lengthwise extension direction of the tube portion 11A is rectangular, the cross section of the elastic line 12 perpendicular to the lengthwise extension direction of the elastic line 12 is circular, and the rectangular cross section of the elastic line 12 is in plane contact with the outer surface of the earphone leg 52 or the outer surface of the temple 63, such that the elastic line 12 having the rectangular cross section is even more unlikely to roll along with the flexible sleeve 11 provided with the circular through hole 112.
5) The length of the connecting line 2 is sufficient to go around to the back of the neck of the user. At this point, if both of the two wireless in-ear audio devices 5 fall off from the ears of the user, the two wireless in-ear audio devices 5 do not become directly lost since the connecting line 2 is hung around the neck of the user. Alternatively, when the glasses frame 6 is taken off from the face of the user, the glasses frame 6 does not become directly lost since the connecting line 2 is hung around the neck of the user.
6) The second target object is the fastener, which is for fastening to clothes on the body of the user or the earlobe of the user. When the wireless in-ear audio device 5 falls off from the ear of the user, with the fastener fastening at the clothes of the user or the earlobe of the user, it is ensured that the wireless in-ear audio device 5 indirectly connected with the fastener does not become directly lost.
7) The thickness T2 between the inner ring edge 31 and the outer ring edge 32 is not greater than the linear distance D1 by which the outer peripheral surface of the flexible sleeve 11 exceeds the outer peripheral surface of the exposed section 122, and the thickness T2 between the inner ring edge 31 and the outer ring edge 32 is less than the thickness T1 of the tube wall of the tube portion 11A, such that the collar 3 can be fittingly engaged between the outer peripheral surface of the exposed section 122 and the outer surface of the earphone leg 52, or be rotatable and movable between the outer peripheral surface of the exposed section 122 and the outer surface of the earphone leg 52.
8) The collar 3 is made of a hard non-metal material and has a low coefficient of friction. More specifically, the material of the collar 3 is ceramic or Teflon™ in a way that the outer surface of the collar 3 is smooth, and sliding occurs due to an extremely small frictional force between the collar 3 and the exposed section 122, such that the exposed section 122 is unlikely to roll and further does not drive the collar 3 to roll. At the same time, with the smooth outer surface of the collar 3, even if the collar 3 rotates around the exposed section 122, the collar 3 is still prevented from scratching the outer surface of the earphone leg 52.
9) The magnetic elements 4 are provided on the corresponding flexible sleeves 11 are located outside the corresponding through holes 112, the two magnetic elements 4 in the two noose units 1 are attractive to each other to be joined together, and the connecting line 2 encloses to form the winding space 21 at this point. By accommodating the neck or the wrist of the user in the winding space 21, that is, by winding the connecting line 2 around the neck or the wrist of the user, when the user is not currently using the two wireless in-ear audio devices 5, the two wireless in-ear audio devices 5 encircled by the two noose units 1 do not become directly lost as being hung on the neck or the wrist of the user, providing ease for portability and requiring no additional storage elements for accommodating the two wireless in-ear audio devices 5.
