In addition, features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present utility model, unless otherwise specified, "multiple" means two or more.

[0034] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0035] like Figure 1 , Figure 2 As shown, the utility model provides an open-type headset, wherein the open-type headset is a smart headset, and the open-type headset can be configured with a call noise reduction function and / or an artificial intelligence noise reduction function, and at the same time, can also be configured with stereo surround and other functions.

[0036] Combination Figure 3 and Figure 4The open-type earphone includes an ear hook 100 and an ear shell 200. The ear hook 100 has a first connecting portion 110, and the first connecting portion 110 is connected to a rotating shaft 400. The ear shell 200 has a second connecting portion 210, and the second connecting portion 210 is arranged opposite to the first connecting portion 110. The second connecting portion 210 is used for the rotating shaft 400 to pass through. The ear shell 200 can rotate relative to the ear hook 100 by relying on the rotating shaft 400.

[0037] It is understandable that the ear hook 100 is used to hang on the user's ear so as to be used for wearing open headphones. Specifically, the ear hook 100 is a curved structure, and its shape is approximately U-shaped, which is convenient for hanging on the user's ear. One end of the ear hook 100 has a first connection part 110; the ear shell 200 is provided with a speaker and other devices inside, and the ear shell 200 has a second connection part 210 arranged opposite to the first connection part 110; one end of the rotating shaft 400 is passed through the first connection part 110, and the other end is passed through the second connection part 210. The ear shell 200 can rotate relative to the ear hook 100 by relying on the rotating shaft 400. In this way, by rotating the ear shell 200, the angle of the ear shell 200 can be adjusted, which is convenient for users to use.

[0038] It should be noted that, in some embodiments, the rotating shaft 400 is fixed to the first connecting part 110, and the second connecting part 210 is rotatable relative to the rotating shaft 400, so that the ear shell 200 can rotate relative to the ear hook 100 by relying on the rotating shaft 400; in other embodiments, the rotating shaft 400 is fixed to the second connecting part 210, and the rotating shaft 400 is rotatable relative to the first connecting part 110, so that the ear shell 200 can rotate relative to the ear hook 100 by relying on the rotating shaft 400.

[0039] Combination Figure 2 and Figure 4 Furthermore, the open earphone also includes a decorative ring 300, the two ends of which are respectively mounted outside the first connecting portion 110 and the second connecting portion 210, and the decorative ring 300 can cover the gap between the first connecting portion 110 and the second connecting portion 210 to play a decorative role.

[0040] like Figure 4 , Figure 5 As shown, an annular adhesive groove 111 is provided on the outer periphery of the first connecting portion 110 , an undercut portion 310 penetrating the annular adhesive groove 111 is provided on the inner wall of the decorative ring 300 , and an adhesive layer for bonding the undercut portion 310 is provided in the annular adhesive groove 111 .

[0041] It can be understood that the cross-section of the first connecting part 110 is annular, the annular glue groove 111 is opened on the outer peripheral wall of the first connecting part 110, and the annular glue groove 111 is coaxially arranged with the first connecting part 110; the undercut portion 310 is arranged on the inner wall of the decorative ring 300, and the undercut portion 310 is annular, and the undercut portion 310 is coaxially arranged with the decorative ring 300; by applying glue in the annular glue groove 111 and sleeve the decorative ring 300 on the first connecting part 110 so that the undercut portion 310 is buckled into the annular glue groove 111, the fixing of the decorative ring 300 and the first connecting part 110 can be achieved, thereby reducing the risk of loosening of the decorative ring 300.

[0042] It should be noted that the adhesive layer is formed by solidifying the glue. In addition, by inserting the undercut portion 310 into the annular glue groove 111, the contact area between the undercut portion 310 and the adhesive layer is large, which can improve the reliability of the connection between the decorative ring 300 and the first connecting portion 110, and further reduce the risk of the decorative ring 300 loosening. At the same time, the adhesive layer can play a sealing role and improve the waterproof effect of the open earphone. Specifically, the adhesive layer is annular and is arranged in the annular glue groove 111, and the adhesive layer is bonded to all parts of the undercut portion 310, thereby ensuring the sealing effect.

[0043] It should be further explained that, before the ear shell 200 is coupled to the rotating shaft 400, the decorative ring 300 can be sleeved on the outside of the first connecting portion 110, and the undercut portion 310 can be buckled into the annular rubber groove 111. At this time, the risk of the decorative ring 300 coming off the first connecting portion 110 can be reduced.

[0044] It should be noted that, in other embodiments, the annular glue groove 111 may be provided on the periphery of the second connection portion 210. It is understandable that, whether the annular glue groove 111 is provided on the periphery of the first connection portion 110 or the second connection portion 210, and the decorative ring 300 is fixed by glue dispensing, compared with no waterproof treatment between the decorative ring 300 and the first connection portion 110 and the second connection portion 210, the waterproof effect of the open-type earphone can be improved and the risk of loosening of the decorative ring 300 can be reduced.

[0045] Combination Figure 4 and Figure 5 In some embodiments, an annular glue groove 111 is provided on the outer periphery of the first connecting portion 110 , and the undercut portion 310 is limitedly matched with the side wall of the annular glue groove 111 on one side close to the second connecting portion 210 .

[0046] It should be noted that the limiting cooperation between the undercut portion 310 and the side wall of the annular glue groove 111 close to the second connection portion 210 means that the side wall of the annular glue groove 111 close to the second connection portion 210 can prevent the decorative ring 300 from escaping from the first connection portion 110 when moving radially. In this way, the risk of the decorative ring 300 escaping from the first connection portion 110 can be reduced.

[0047] Furthermore, the radial thickness of the undercut portion 310 gradually increases along the arrangement direction from the first connection portion 110 to the second connection portion 210. The radial thickness of the undercut portion 310 refers to the thickness of the undercut portion 310 in the radial direction of the undercut portion 310.

[0048] It can be understood that the undercut portion 310 is elastic and will be compressed when subjected to radial force. In this way, when the decorative ring 300 is gradually pushed into the first connecting portion 110, the undercut portion 310 will be squeezed first. When the thicker side of the undercut portion 310 enters the annular glue groove 111, the undercut portion 310 is restored and inserted into the annular glue groove 111, and cooperates with the side wall limit of the annular glue groove 111 on the side close to the second connecting portion 210.

[0049] Combination Figure 4 and Figure 5 In some embodiments, an annular glue groove 111 is provided on the outer periphery of one of the first connection portion 110 and the second connection portion 210, and a step 211 is formed on the outer periphery of the other of the first connection portion 110 and the second connection portion 210. The step 211 includes a first step surface 211a and a second step surface 211b. The width direction of the first step surface 211a is parallel to the axial direction of the rotating shaft 400, and the second step surface 211b is connected to the side of the first step surface 211a away from the annular glue groove 111. The inner wall of the decorative ring 300 is opposite to the first step surface 211a, and the end wall of the decorative ring 300 away from the annular glue groove 111 is opposite to the second step surface 211b.

[0050] Specifically in this embodiment, an annular glue groove 111 is provided on the outer periphery of the first connecting part 110, and a step 211 is formed on the outer periphery of the second connecting part 210. By sleeve-fitting the decorative ring 300 on the outside of the first step surface 211a of the step 211, and making the end wall of the decorative ring 300 away from the annular glue groove 111 face the second step surface 211b of the step 211, the length of the gap between the second connecting part 210 and the decorative ring 300 is increased, thereby improving the waterproof performance.

[0051] Furthermore, the maximum width of the gap between the inner wall of the decorative ring 300 and the first step surface 211a is less than or equal to 0.1 mm, and further, the maximum width of the gap between the end wall of the decorative ring 300 away from the annular adhesive groove 111 and the second step surface 211b is less than or equal to 0.1 mm. In this way, the waterproof effect of the open-type earphone can be ensured.

[0052] Combination Figure 5 , Figure 6 and Figure 7 In some embodiments, the inner wall of the decorative ring 300 is provided with an annular assembly groove, and a bluff body 320 is arranged in the annular assembly groove. The bluff body 320 is arranged opposite to the first step surface 211 a.

[0053] Specifically, the annular assembly groove is coaxially arranged with the decorative ring 300, and the bluff body 320 is also an annular structure. The bluff body 320 is installed in the annular assembly groove and is coaxially arranged with the annular assembly groove. The bluff body 320 can prevent water from flowing into the interior of the ear shell 200 through the gap between the inner wall of the decorative ring 300 and the first step surface 211a.

[0054] In some embodiments, the bluff body 320 includes an annular water absorbing portion 321 disposed in the annular assembly groove, and multiple soft water absorbing portions 322 disposed on the inner wall of the annular water absorbing portion 321 . The multiple soft water absorbing portions 322 are disposed along the circumference of the annular water absorbing portion 321 and contact the first step surface 211 a .

[0055] It should be noted that the baffle body 320 is made of a water-absorbing material, such as water-absorbing cotton. When water enters the gap between the first step surface 211a and the inner wall of the decorative ring 300, the soft water-absorbing portion 322 will drain the water to the annular water-absorbing portion 321, thereby reducing the risk of water entering the ear shell 200 and improving the waterproof effect. In addition, the soft water-absorbing portion 322 is a soft structure, which is in contact with the first step surface 211a. When the ear shell 200 rotates, the soft water-absorbing portion 322 will not hinder the second connection portion 210 from rotating relative to the decorative ring 300, and the second connection portion 210 will not be damaged when it rotates relative to the decorative ring 300.

[0056] In other embodiments, the baffle body 320 is a sealing ring that is sleeved on the outside of the first step surface 211a. The sealing ring is interference fit with the first step surface 211a. The sealing ring can seal the gap between the first step surface 211a and the inner wall of the decorative ring 300. At the same time, the sealing ring can also provide a damping effect when the ear shell 200 rotates relative to the ear hook 100.

[0057] In the open-type earphone of the present invention, the ear hook 100 is used to hang on the ear of the user so as to wear the open-type earphone, and the ear shell 200 can rotate relative to the ear hook 100 by means of the rotating shaft 400. In this way, by rotating the ear shell 200, the angle of the ear shell 200 can be adjusted, which is convenient for the user to use. An annular glue groove 111 is provided on the outer periphery of one of the first connecting portion 110 and the second connecting portion 210, and an undercut portion 310 is provided on the inner wall of the decorative ring 300 and is penetrated in the annular glue groove 111. By applying glue in the annular glue groove 111 and sleeve the decorative ring 300 on the first connecting portion 110 and the second connecting portion 210 so that the undercut portion 310 is buckled into the annular glue groove 111, the decorative ring 300 can be fixed, and the risk of the decorative ring 300 loosening can be reduced. In addition, by inserting the undercut portion 310 into the annular adhesive groove 111, the contact area between the undercut portion 310 and the adhesive layer is large, which can improve the reliability of the fixing of the decorative ring 300 and further reduce the risk of loosening of the decorative ring 300. At the same time, the adhesive layer can also play a sealing role to improve the waterproof effect of the open-type earphone.
