[0029] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0030] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but rather merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by a person of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0031] Example 1

[0032] like Figure 1 As shown, it includes at least one flexible hollow catheter body 1 and a protective sleeve 2 wrapped around the hollow catheter body 1; the protective sleeve 2 is a braided sleeve, and the hollow catheter body 1 is a separate design.

[0033] In this embodiment, one hollow catheter body 1 is provided.

[0034] The hollow catheter body 1 can be made of, but not limited to, a hose made of PE or silicone material.

[0035] The protective cover 2 is used to protect the hollow catheter body 1 and is placed on the outside of the hollow catheter body 1. The two are designed to be separated, so that the protective cover 2 can be easily replaced when it is severely worn, so as to achieve the reuse of the hollow catheter body 1, reduce resource waste, and reduce use costs.

[0036] When the headphone cable of the present application is in use, one end is connected to the earplug 8 and placed in the user's ear, and the other end is connected to the speaker end. The sound emitted by the speaker end will be transmitted to the earplug 8 through the hollow catheter body 1 and then heard by the user.

[0037] In order to facilitate connecting the two ends of the hollow catheter body 1 to the earplug 8 and the speaker end respectively, the two ends of the hollow catheter body 1 extend from the corresponding ends of the protective sleeve 2 respectively.

[0038] In order to prevent the protective sleeve 2 from moving around freely outside the hollow catheter body 1 and affecting its protective effect, both ends of the protective sleeve 2 are fixed to the outer wall of the hollow catheter body 1 .

[0039] In order to fix the end of the protective sleeve 2 , the end of the protective sleeve 2 is connected to the hollow catheter body 1 through glue 3 .

[0040] Preferably, the glue 3 can be quick-drying glue 3.

[0041] The fixing method of the end portion of the protective sleeve 2 and the hollow catheter body 1 is not limited to the bonding with the glue 3 , and a heat shrink tubing can also be used for fixing.

[0042] Since the outside of the hollow catheter body 1 is wrapped with a protective cover 2, the problem of wear and tear of the hollow catheter body 1 can be effectively prevented. When the end of the hollow catheter body 1 is connected to the earplug 8 or the speaker end, the broken end can be directly cut off, and then a section of the protective cover 2 can be cut off to extend the hollow catheter body 1 at this end from the protective cover 2, and finally the protective cover 2 at this end is fixed to the hollow catheter body 1 using quick-drying glue.

[0043] The headphone cable of the present application can directly cut off the damaged part when the end is broken, and the remaining part can continue to be used normally without causing the entire headphone cable to be scrapped. It is convenient to use and can also reduce waste of resources.

[0044] Example 2

[0045] like Figure 2 As shown, based on Example 1, this embodiment further provides an air duct type earphone cable, whose structure is substantially the same as that of Example 1, except that:

[0046] The end of the hollow catheter body 1 is flush with the end of the protective sheath 2 .

[0047] The hollow catheter body 1 and the end of the protective sleeve 2 can be fixed together using glue 3, and then the two can be connected as a whole when connected to the earplug 8 or the speaker end.

[0048] The protective cover 2 of this type of headphone cable with flush ends can be completely bonded to the hollow conduit body 1. When the end of the headphone cable is damaged, the damaged part can be directly cut off and the remaining part can continue to be used.

[0049] Example 3

[0050] like Figure 3 As shown, based on Example 1, this embodiment further provides an air duct type earphone cable, whose structure is substantially the same as that of Example 2, except that:

[0051] The hollow catheter bodies 1 include two, and ends on either side of the two hollow catheter bodies 1 are connected together.

[0052] The ends of either side of the two hollow conduit bodies 1 can be fixed with a first heat shrink tubing 4, which facilitates connecting the two to the same speaker end, while the free ends of the two hollow conduit bodies 1 can be connected to earplugs 8 respectively, making it convenient for the headphones to be used with both ears.

[0053] In addition, the ends of the two hollow catheter bodies 1 on the same side can also be directly bonded together using glue.

[0054] Example 4

[0055] like Figure 4-5 As shown, based on Example 1, this embodiment further provides an air duct type earphone cable, whose structure is substantially the same as that of Example 1, except that:

[0056] A detachable metal tube 5 is installed at at least one end of the hollow catheter body 1 .

[0057] Adding a metal tube 5 at the end of the hollow conduit body 1 can facilitate connecting the earphone cable to the earplug 8 and the speaker end.

[0058] In this embodiment, metal tubes 5 are installed at both ends of the hollow catheter body 1 .

[0059] Specifically, there are three ways to connect the metal tube 5 and the hollow catheter body 1:

[0060] The first method is that the outer diameter of the metal tube 5 matches the inner diameter of the hollow catheter body 1 , and the metal tube 5 can be directly inserted into the end of the hollow catheter body 1 to achieve the connection between the two. This connection method can facilitate the disassembly of the metal tube 5 .

[0061] The second method is to provide a second heat shrink tubing 7 at the connection between the metal tube 5 and the hollow conduit body 1 to ensure a secure connection between the metal tube 5 and the hollow conduit body 1. Specifically, after the metal tube 5 is inserted into the hollow conduit body 1, the second heat shrink tubing 7 can be used to secure the connection between the two. This method provides a more secure connection, and is used in this embodiment.

[0062] The third type: Since the hollow catheter body 1 is a flexible tube, its tube wall has a certain elasticity. A metal tube 5 with an outer diameter slightly larger than the inner diameter of the hollow catheter body 1 can also be selected. In this way, after the metal tube 5 is connected to the hollow catheter body 1, the elastic force of the tube wall of the hollow catheter body 1 can increase the stability of the connection between it and the metal tube 5.

[0063] In order to prevent dust from entering the hollow conduit body 1 and affecting the sound transmission effect, a dustproof net 6 is provided inside the end of the metal tube 5 away from the hollow conduit body 1 .

[0064] The dust screen 6 can be directly welded into the metal tube 5 , or can be installed in the metal tube 5 in a detachable manner, so that the dust screen 6 can be easily disassembled and cleaned.

[0065] In this embodiment, when either end of the headphone wire is damaged, first cut the second heat shrink tubing 7 outside the metal tube 5 of the damaged end, then remove the metal tube 5 from the hollow catheter body 1, and then cut the damaged end of the headphone wire in the manner of Example 1 and re-fix the protective cover 2 with glue 3, and finally reinsert the metal tube 5 into the hollow catheter body 1 at that end and fix it with the second heat shrink tubing 7. The operation is simple and convenient.

[0066] The structure for facilitating connection of the hollow tube body 1 is not limited to the metal tube 5. Hardened glue can also be used to harden the end of the hollow tube body 1, thereby facilitating connection with the earplug 8 or the speaker end.

[0067] Example 5

[0068] like Figure 6 As shown, based on Example 4, this embodiment further provides an air duct type earphone cable, whose structure is substantially the same as that of Example 2, except that:

[0069] An earplug 8 is provided at either end of the hollow catheter body 1 .

[0070] In this embodiment, the hollow catheter body 1 is assembled into the inner hole of the earplug 8 via the metal tube 5 .

[0071] Specifically, a protrusion is provided on the outer wall of the metal tube 5, and a groove is provided on the inner wall of the inner hole of the earplug 8. After the metal tube 5 is inserted into the inner hole of the earplug 8, the protrusion can be stuck in the groove to achieve a firm fit between the two.

[0072] The connection method between the earplug 8 and the hollow catheter body 1 is not limited to this. The earplug 8 can also be injection-molded as one piece with the hollow catheter body 1. In this way, there is no need to install the metal tube 5; or after the metal tube 5 is assembled into the inner hole of the earplug 8, the metal tube 5 and the earplug 8 can be fixed using quick-drying glue or heat shrink tubing.

[0073] In addition, the shape of the earplug 8 is not limited to the one disclosed in this embodiment.

[0074] Based on the above-mentioned ideal embodiment of the present invention, and in accordance with the above description, relevant personnel can make various changes and modifications without departing from the technical scope of the present invention. The technical scope of the present invention is not limited to the content of the specification, but must be determined according to the scope of the claims.
