[0002] Currently, the usage rate of wireless Bluetooth earphones is increasing day by day among consumer groups. However, for wireless Bluetooth earphones, only earplugs are installed as the member connected to the human body, and the method of wearing the wireless Bluetooth earphones on the human body is only the method of inserting the earplugs into the ears of the human body. Such a wearing method is unstable, and with just a little force, the wireless Bluetooth earphones may fall off the human ear, or the wireless Bluetooth earphones are likely to fall off the human ear during exercise such as running. Considering this "inherent defect" of wireless Bluetooth earphones, the phenomenon of losing wireless Bluetooth earphones is not uncommon. Since the cost of wireless Bluetooth earphones is higher than that of conventional wired earphones, it is necessary to design an anti-loss rope and an anti-loss device to prevent the loss of wireless Bluetooth earphones and overcome the above problems.

Best Mode for Carrying Out the Invention

[0026] Hereinafter, embodiments of the present invention will be described in detail. However, the present invention is not limited thereto, and various modifications are possible within the described scope. Embodiments obtained by appropriately combining the technical means disclosed in different embodiments are also included in the technical scope of the present invention.

[0027] FIGS. 1 to 4 are an example of a specific embodiment of the loss prevention device of the present invention. The loss prevention device includes a loss prevention rope 100, a pair of wireless in-ear audio devices 200, and a storage box 300. The loss prevention rope 100 is used to connect to the wireless in-ear audio device 200, and the wireless in-ear audio device 200 is stored in the storage box 300. In the present invention, the wireless in-ear audio device 200 may be a related article that emits sound by being inserted into the user's ear, such as a wireless Bluetooth earphone or a wireless hearing aid. The pair of wireless in-ear audio devices 200 according to this embodiment are two wireless earphones, and the storage box 300 is a charging case for the wireless in-ear audio device 200.

[0028] As shown in FIGS. 1 to 3, the anti-loss rope 100 includes a rope kit 1 and two connection mechanisms 2 respectively connected to the rope kit 1. The rope kit 1 includes a rope 10 having two free ends and an adjustment unit 13. The rope kit 1 has a holding loop 11, a joint portion P, and two connection portions 12. The rope 10 has the holding loop 11 and the connection portion 12. The joint portion P forms the holding loop 11 and the connection portion 12 on the rope 10, and the joint portion P is located between the holding loop 11 and the connection portion 12. Each of the connection mechanisms 2 is used to connect to one of the wireless in-ear audio devices 200. The connection portion 12 may be used to wind around the outer periphery of the storage box 300. The holding loop 11 is covered on the outer periphery of the storage box 300 to prevent the scattering of the rope kit 1.

[0029] As shown in FIGS. 1 to 3, after the connection between the two connection mechanisms 2 and a pair of the wireless in-ear audio devices 200 is completed, the pair of wireless in-ear audio devices 200 are stored in the earphone storage chamber of the storage box 300, and the cover of the storage box 300 is used to cover the earphone storage chamber, so that the storage of the wireless in-ear audio devices 200 is completed. One end of each of the connection portions 12 away from the joint portion P is at least partially stored in the storage box 300, and the two connection portions 12 are wound along the outer periphery of the storage box 300 in the same direction at the exposed portion of the storage box 300. The holding loop 11 is covered on the same outer periphery of the storage box 300 where the connection portion 12 is wound, or the holding loop 11 is covered on the storage box 300 perpendicular to the outer periphery of the storage box 300 where the connection portion 12 is wound (see FIG. 4).

[0030] FIGS. 5 to 13 are an example of a specific embodiment of the anti-loss rope of the anti-loss device of the present invention.

[0031] As shown in FIGS. 5 to 7, the rope 10 is an elastic rope, the adjustment unit 13 is a round bead similar to a columnar structure, and the adjustment unit 13 has a through hole 131. The rope 10 passes through the through hole 131 twice, and the holding loop 11 is formed by winding the rope 10 around the adjustment unit 13 once. The rope 10 forms the joint portion P jointly with the adjustment unit 13 at the position of the adjustment unit 13, and the rope 10 forms two connection portions 12 on both sides of the adjustment unit 13. That is, the two free ends of the rope 10 penetrate through the opposite sides of the through hole 131 in a bidirectional manner, and the connection portion 12 is formed at the portion where the rope 10 protrudes from the through hole 131. The two connection portions 12 are respectively located on both sides of the through hole 131, making it difficult for the adjustment unit 13 to detach from the rope 10. There are various types of implementation methods for the joint portion P according to the present invention, and the above-described implementation method of the joint portion P is one of the embodiments of the joint portion P of the anti-loss rope 100 according to the present invention.

[0032] As shown in FIGS. 6 and 7, the rope 10 is movably connected to the adjustment unit 13 within the through hole 131. To be applicable to storage boxes 300 of different sizes, the size of the holding loop 11 is adjusted by moving the position of the adjustment unit 13 on the rope 10 (see FIG. 3). Specifically, the size of the holding loop 11 is adjusted by pulling the connection portion 12 or the holding loop 11. In other embodiments, the adjustment unit 13 is connected to be fixed to the rope 10 by riveting or an adhesive method, the position of the joint portion P is fixedly fixed, and to be applicable to storage boxes 300 of different sizes, the size of the holding loop 11 is adjusted by changing the elasticity of the elastic rope.

[0033] As shown in FIGS. 5 and 8, the connection mechanism 2 is a circlip integrally formed by bending a metal wire. The cross-section of the metal wire is preferably provided to exhibit a circular shape, but is not limited to a circular shape and may be other shapes such as a rectangle. The connection mechanism 2 has a first coupling portion 21, a second coupling portion 22, and a circlip 23 connected to the first coupling portion 21 and the second coupling portion 22. The circlip 23 is formed by bending the metal wire into a C shape, and an engagement space J is formed inside the circlip 23. An opening 24 is formed by spacing the first coupling portion 21 and the second coupling portion 22 apart, and the opening 24 communicates with the engagement space J. The first coupling portion 21 has a first through hole 211, the second coupling portion 22 has a second through hole 221, the connection portion 12 passes through the first through hole 211 and the second through hole 221 and is connected to the second coupling portion 22 by a coupling method, and the connection portion 12 is connected to the second coupling portion 22.

[0034] As shown in FIGS. 5 and 8, the first coupling portion 21 and the second coupling portion 22 are installed so as to face each other in a first direction, and the distance L1 between the first coupling portion 21 and the second coupling portion 22 in the first direction is shorter than the maximum distance L2 of the engagement space J in the first direction (see FIG. 6). When the wireless in-ear audio device 200 is engaged with the engagement space J, it becomes difficult for the wireless in-ear audio device 200 to be detached from the engagement space J through the opening 24. The connection portion 12 movably passes through the first through hole 211, and by pulling the connection portion 12, the length of the connection portion 12 located between the first through hole 211 and the second through hole 221 can be freely adjusted. The opening 24 allows the wireless in-ear audio device 200 to pass through and be engaged with the engagement space J. In other embodiments, the connection portion 12 may be connected to the second coupling portion 22 by other methods.

[0035] FIGS. 9 to 13 are schematic configuration diagrams showing the wireless in-ear audio device 200 of the loss prevention device of the present invention.

[0036] As shown in FIGS. 9 and 10, the wireless in-ear audio device 200 has a head 3, a rod 4, and an ear cap 5 that covers the head 3 and is firmly connected to the head 3 along the engagement direction. The head 3 is integrally connected to the rod 4, and the head 3 is provided with earphones 31 and an engagement slot 32 provided around the earphones 31. The ear cap 5 has a fastening convex portion 51 and a flexible ear cover 52 connected to the fastening convex portion 51, and the ear cap 5 has a structure integrally formed of a silicone material. By engaging the fastening convex portion 51 with the engagement slot 32, the ear cap 5 is fixed to the head 3, and the flexible ear cover 52 is covered outside the fastening convex portion 51.

[0037] As shown in FIGS. 11 and 13, the connection mechanism 2 and the portion of the connection portion 12 located between the first coupling portion 21 and the second coupling portion 22 jointly cover the outer periphery of the fastening convex portion 51.

[0038] As shown in FIGS. 10 to 13, the connection step of the connection mechanism 2 and the wireless in-ear audio device 200 adjusts the length of the connection portion 12 at the locations of the first through hole 211 and the second through hole 221 movably by the first through hole 211. The space formed among the connection portion 12, the first coupling portion 21, and the second coupling portion 22 is larger than the maximum outer diameter of the ear cap 5. When the flexible ear cap 5 is turned inside out and placed in the space, the wireless in-ear audio device 200 further engages with the engagement space J by moving the circlip 23 or the flexible ear cap 5. Specifically, by the fastening convex portion 51 passing through the opening 24, the wireless in-ear audio device 200 engages with the engagement space J, and the connection portion 12 contracts in the direction approaching the joint portion P, so that the opening 24 is constricted. A part of the circlip 23 and the connection portion 12 jointly cover the fastening convex portion 51 and is constructed between the flexible ear cover 52 and the fastening convex portion 51, and thus the installation is completed. In another embodiment, the connection mechanism 2 may be fastened to the rod 4 of the wireless in-ear audio device 200.

[0039] As shown in FIGS. 10 and 11, by pulling the connection portion 12 in the direction approaching the second coupling portion 22, the length of the connection portion 12 between the first coupling portion 21 and the second coupling portion 22 is extended, and by opening the first coupling portion 21 and the second coupling portion 22 toward both sides, the opening 24 is opened outward. When the opening 24 is opened until the distance between the first coupling portion 21 and the second coupling portion 22 in the first direction becomes equal to or greater than the maximum diameter of the fastening convex portion 51, the wireless in-ear audio device 200 is removed, and the wireless in-ear audio device 200 can be removed from the connection mechanism 2.

[0040] Figures 14 and 15 show other embodiments of the joint portion P of the anti-loss rope 100 of the present invention. In the above-described embodiments of the anti-loss rope 100, the structures of other embodiments of the joint portion P are all adopted. In this embodiment, the rope 10 passes through the through hole 131 three times, and the rope 10 is wound around the adjustment unit 13 twice. One turn forms the holding loop 11, and the other turn is fastened to the adjustment unit 13. Specifically, the two free ends of the rope 10 penetrate the through hole 131 bidirectionally from both opposite sides of the through hole 131, and one of the free ends is wound again and penetrates the through hole 131 again from the same direction as the first penetration. By doing so, the size of the holding loop 11 can be adjusted by pulling one of the connection portions 12 and the holding loop 11 connected to the other free end. When the deviation between the sizes of the through hole 131 and the rope 10 is large, the adjustment unit 13 is wound twice to increase the frictional force between the rope 10 and the adjustment unit 13, thereby achieving the same effect. Since there is no need to replace the rope 10 and the adjustment unit 13 of other sizes, the cost is reduced.

[0041] According to the anti-loss rope and the anti-loss device of the present invention, the following effects are achieved.

[0042] 1. By installing the holding loop 11 for covering the outer periphery of the storage box 300 on the rope kit 1, the rope kit 1 can be sorted out and easily stored in the storage box 300. By doing so, it is possible to prevent the situation where the rope kit 1 is not properly stored and scattered and the rope kit 1 is entangled.

[0043] 2. By using an elastic rope to form the rope kit 1, the size of the holding loop 11 can be adjusted by changing the elasticity of the elastic rope, and it can also be applied to the storage boxes 300 of different sizes.

[0044] 3. By installing the adjustment unit 13, the rope 10 penetrates through the through-hole 131 at least twice, and the rope 10 winds around the adjustment unit 13 at least once. Among them, the holding loop 11 is formed in one winding. In addition, the rope 10 forms the joint portion P jointly with the adjustment unit 13 at the position of the adjustment unit 13, and the size of the holding loop 11 is realized by moving the adjustment unit 13 to different positions of the rope 10. By doing so, it is applicable to the storage boxes 300 with different sizes.

[0045] 4. The rope 10 penetrates through the through-hole 131 three times, and the rope 10 winds around the adjustment unit 13 twice and is tightened to the adjustment unit 13 by winding one more time. If the diameter of the rope 10 is too small and the difference between the through-hole 131 of the adjustment unit 13 is too large, the friction between the rope 10 and the adjustment unit 13 will become insufficient. By winding the adjustment unit 13 twice and winding one more time to tighten it to the adjustment unit 13 and increasing the friction between the rope 10 and the adjustment unit 13, it becomes difficult to slide the adjustment unit 13.

[0046] 5. By providing the connection mechanism 2 with the first coupling portion 21, the second coupling portion 22, and the circlip 23 connected to the first coupling portion 21 and the second coupling portion 22, the engagement space J is formed inside the circlip 23, and the opening 24 is formed by spacing the first coupling portion 21 and the second coupling portion 22 apart. By providing the first through hole 211 in the first coupling portion 21, the connection portion 12 passes through the first through hole 211 and is connected to the second coupling portion 22. The connection portion 12 passes through the first through hole 211 movably, and by pulling the connection portion 12, the length of the connection portion 12 located between the first through hole 211 and the second through hole 221 can be freely adjusted. The connection portion 12 between the first through hole 211 and the second through hole 221 forms a space, which makes it easier to cover the outside of the wireless in-ear audio device 200. The opening 24 allows the wireless in-ear audio device 200 to pass through and engage with the engagement space J, and the wireless in-ear audio device 200 is surrounded by the first coupling portion 21, the circlip 23, the second coupling portion 22, and the connection portion 12 located between the first coupling portion 21 and the second coupling portion 22, making it difficult for the wireless in-ear audio device 200 to fall off.

[0047] 6. The flexible ear cover 52 is covered outside the fastening convex portion 51, and the connection mechanism 2 is covered by the fastening convex portion 51 and constructed between the flexible ear cover 52 and the fastening convex portion 51. Compared with the case where the connection mechanism 2 is covered by the rod 4, the wireless in-ear audio device 200 is less likely to be damaged or broken, and the anti-loss rope 100 is less likely to detach from the wireless in-ear audio device 200.

[0048] 7. Since the distance between the first coupling portion 21 and the second coupling portion 22 in the first direction is shorter than the maximum distance of the engagement space J in the first direction, when the wireless in-ear audio device 200 engages with the engagement space J, it becomes difficult for the wireless in-ear audio device 200 to disengage from the engagement space J through the opening 24.

[0049] As described above, the present invention has been described using embodiments. However, the technical scope of the present invention is not limited to the scope described in the above embodiments. It is obvious to those skilled in the art that various changes or improvements can be made to the above embodiments. It is clear from the description of the claims that forms with such changes or improvements can also be included in the technical scope of the present invention.
