[0002] At present, rear-hook bone conduction earphones or other earphones are widely used. For rear-hook earphones, the length or size of the U-shaped rear hook they adopt is generally determined, while the head shapes of human beings are not the same. Therefore, it is obviously difficult to match the head shapes of many users with a rear hook of a fixed size. Therefore, there are the following inconveniences when using: the rear hook is too long, resulting in a large gap between it and the head, and the wearing is unstable and uncomfortable; when wearing a helmet after wearing the rear-hook earphone, the rear hook will interfere with the helmet; when the user shakes his head, the rear hook will interfere with the collar, resulting in unstable wearing of the earphone. In view of the above deficiencies, it will bring a bad user experience to the user. Summary of the Utility Model

[0003] In order to overcome the deficiencies of the prior art, the purpose of the utility model is to provide an adjustable rear-hook structure for earphones.

[0004] The technical solution is as follows: an adjustable rear-hook structure for earphones, including a rear hook, and a power cord is arranged inside the rear hook; it also includes a left shell with two ends respectively connected to the left ear hook and the left end of the rear hook of the earphone, and a right shell with two ends respectively connected to the right ear hook and the right end of the rear hook of the earphone; a left adjusting member and a right adjusting member are respectively fixed inside the left shell and the right shell; a left connecting member and a right connecting member are respectively fixed at the left end and the right end of the rear hook; the front end of the left connecting member is inserted into the left shell and is movably connected to the left adjusting member, and the front end of the right connecting member is inserted into the right shell and is movably connected to the right adjusting member; when the left connecting member is driven to move relative to the left adjusting member and the right connecting member is driven to move relative to the right adjusting member, frictional resistance will be generated.

[0005] A wiring box for connecting the speaker and the power cord to a cable is also arranged on the rear hook. The cable is used to connect different connectors and match different walkie-talkies.

[0006] Preferably, both the left adjusting member and the right adjusting member are made of flexible materials, and both the left connecting member and the right connecting member are made of hard materials.

[0021] In order to enable those skilled in the art to better understand the solution of the present utility model, the present utility model will be further described in detail below with reference to the drawings and embodiments.

[0022] As Figure 1-2 shown, the embodiment of the present utility model provides an adjustable rear - hook structure for a headset. Here, the headset mainly refers to a rear - hook type head - worn headset; it includes a rear hook 1, and a power cord 10 is arranged inside the rear hook; it further includes a left housing 4 whose two ends are respectively connected to the left ear hook 2 and the left end of the rear hook of the headset, and a right housing 5 whose two ends are respectively connected to the right ear hook 3 and the right end of the rear hook of the headset; bone conduction speakers 11 are arranged at the ends of the left ear hook 2 and the right ear hook 3 respectively; left adjusting members 6 and right adjusting members 7 are respectively fixed inside the left housing and the right housing; left connecting members 8 and right connecting members 9 are respectively fixed at the left end and the right end of the rear hook 1; the front end of the left connecting member is inserted into the left housing 4 and is movably connected to the left adjusting member 6, and the front end of the right connecting member is inserted into the right housing 5 and is movably connected to the right adjusting member 7; when driving the left connecting member to move relative to the left adjusting member 6 and the right connecting member 9 to move relative to the right adjusting member 7, frictional resistance will be generated. The two ends of the power cord 10 respectively pass through the left housing 4, the right housing 5, the left ear hook 2, and the right ear hook 3 and are connected to the bone conduction speaker 11. Here, the so - called movable connection means that when a certain external force is applied to the two connected components, the two can move relative to each other. For example, when pulling the left connecting member 8 with force, it can move a certain distance relative to the left adjusting member 6, and when there is no external force, the two will not move relative to each other.

[0023] As Figure 2-4As shown, specifically, in this embodiment, the left adjusting member 6 and the right adjusting member 7 are both made of flexible materials, such as common silicone, which has good frictional damping; correspondingly, the left connecting member 8 and the right connecting member 9 are both made of hard materials, such as hard plastic. The left adjusting member 6 and the right adjusting member 7 in this embodiment are both in a circular shape. Correspondingly, the left connecting member 8 and the right connecting member 9 are both made of hard plastic and are in a rod shape. The front ends of the two are respectively inserted into the left housing 4 and the right housing 5 and are respectively arranged along the length directions of the left housing and the right housing; the left adjusting member and the right adjusting member are respectively sleeved on the left connecting member and the right connecting member. And the left adjusting member 6 and the right adjusting member 7 are respectively in interference fit with the left connecting member 8 and the right connecting member 9. It should be noted here that when selecting the materials of the left adjusting member 6 and the left connecting member 8, and the right adjusting member 7 and the right connecting member 9, obviously, among the left adjusting member and the left connecting member, and the right adjusting member and the right connecting member, in addition to one of the components being made of flexible materials and the other being made of hard materials, such as the left adjusting member 6 being made of flexible materials and the left connecting member 8 being made of hard materials, and vice versa; in this embodiment, both of them can be made of flexible materials and have the same effect; and the left adjusting member 6 and the right adjusting member 7 are respectively in interference fit with the left connecting member 8 and the right connecting member 9, in order to generate frictional resistance when driving the left connecting member to move relative to the left adjusting member 6 and the right connecting member 9 to move relative to the right adjusting member 7, and when there is no external force, the two connected parts will not move relative to each other.

[0024] Specifically, the left front end and the right front end of the left housing 4 and the right housing 5 respectively connected to the left end and the right end of the rear hook 1 are respectively provided with through holes for the left connecting member 8 and the right connecting member 9 to pass through, that is, a through hole is provided in the left front end of the left housing 4 connected to the left end of the rear hook 1, and a through hole is also provided in the right front end of the right housing 5 connected to the right end of the rear hook 1, and the through holes are respectively for the left connecting member 8 and the right connecting member 9 to pass through.

[0025] As Figure 2-4 shown, the front ends of the left connecting member 8 and the right connecting member 9 are respectively provided with a left anti - detachment protrusion 801 and a right anti - detachment protrusion 901, which are respectively used to prevent the left connecting member from detaching from the left adjusting member 6 and the right connecting member from detaching from the right adjusting member 7. Here, the left anti - detachment protrusion 801 is integrally formed with the left connecting member 8, and the right anti - detachment protrusion 901 is integrally formed with the right connecting member 9.

[0026] The rear end of the left connecting member 8 is fixedly connected to the left end of the rear hook, and the rear end of the right connecting member 9 is fixedly connected to the right end of the rear hook.

[0027] As Figure 2 shown, a junction box 12 for connecting the speaker and the power cord 10 to the cable is also provided on the rear hook 1. The cable 13 is used to connect different connectors and match different walkie - talkies.

[0028] As Figure 5-6 shown, in summary, for the rear hook structure here, first, left and right shells 4 and 5 are respectively arranged at the positions where the left and right ends of the original rear hook 1 of the earphone are respectively connected to the left ear hook 2 and the right ear hook 3, and left and right adjusting members 6 and 7 are respectively arranged inside the two. The front ends of the left connecting member 8 and the right connecting member 9 are respectively inserted into the left shell 4 and the right shell 5 and are respectively movably connected to the left adjusting member 6 and the right adjusting member 7. That is, the left connecting member 8 can move horizontally (extend and contract) relative to the left shell 4 and the left adjusting member 6, while the right connecting member 9 can move horizontally (extend and contract) relative to the right shell 5 and the right adjusting member 7. The left shell 4 and the right shell 5 here respectively provide accommodation spaces for the extension and contraction of the left connecting member 8 and the right connecting member 9. When the left connecting member 8 and the right connecting member 9 move relative to the left adjusting member 6 and the right adjusting member 7 respectively, frictional resistance will be generated, which can prevent the left connecting member 8 and the right connecting member 9 from moving relative to the left adjusting member 6 and the right adjusting member 7 respectively by themselves without external force after the length adjustment of the rear hook 1 is completed, thus bringing a bad user experience.
