Description

Technical Field

[0001] The utility model relates to electronic products, in particular to ear-hanging headphones. Background Art

[0002] The headset includes a host and an ear hook. The ear hook is hung on the ear, and the host produces sound. The sound-emitting hole of the host is aligned with the ear hole of the user, so that the user can effectively receive the sound. However, in actual use, since the shape and size of the user's ears are different, when the ear hook is fixed on the ear, the sound-emitting hole of the host may not be aligned with the ear hole of the user. Utility Model Content

[0003] The technical problem solved by the utility model is that since the shapes and sizes of the ears of users are different, when the main unit and the ear hook are fixedly connected, the sound hole of the main unit may not be aligned with the ear hole of the user when the ear hook is fixed on the ear.

[0004] To solve the above technical problems, the utility model provides the following technical solutions: an earphone, comprising a host and an ear hook, the ear hook is fixed with an annular positioning piece, the host is connected with an embedded piece, the embedded piece is fitted in the annular positioning piece, and the outer side of the embedded piece and the inner side of the annular positioning piece are matched to design a positioning structure.

[0005] According to the above technical solution, the ear hook is hung on the ear, and the host makes sound. If the sound hole of the host is not aligned with the user's ear hole, the user can drive the host to rotate it at an appropriate angle relative to the ear hook so that the sound hole of the host is aligned with the user's ear hole, and the user can effectively receive the sound.

[0006] When the host rotates relative to the ear hook, the host drives the embedded component to rotate in the annular positioning component. The positioning structure designed in cooperation with the embedded component and the annular positioning component can make the host stay in the position after rotation. The positioning structure temporarily locks the relative position of the host and the ear hook. The user turns the host with force, and the lock is released.

[0007] The positioning structure comprises a tooth-shaped structure arranged on the inner side of the annular positioning piece, and a positioning protrusion arranged on the outer side of the embedded piece, and the positioning protrusion can be engaged in the tooth-shaped structure.

[0008] The positioning convex point is arranged on the arc structure of the circumference of the embedded part. The arc structure is circumferential and is located outside the embedded part, with a gap between it and the center part of the embedded part. In this way, when the positioning convex point is stressed, the arc structure can be elastically deformed away from or close to the center part of the embedded part. This elastic deformation can make the positioning convex point cooperate with the tooth structure to lock the position of the host, and can also increase the user's hand feeling when turning the host.

[0009] The rotating shaft of the embedded component is positioned on the positioning piece, and the positioning piece is connected to the host. The positioning piece is provided with a positioning hole matched with the rotating shaft.

[0010] The embedded component is connected to the host through the cooperation of the polygonal structure and the polygonal groove, and the polygonal structure is arranged on the rotation center line of the embedded component. As an option, the polygonal structure is arranged on the embedded component, and the polygonal groove is arranged on the host. The cooperation of the polygonal structure and the polygonal groove can enable the host to drive the embedded component to rotate synchronously. The polygonal structure and the rotating shaft are respectively located on both sides of the embedded component.

[0011] The annular positioning member is fixedly connected to the ear hook through the connecting arm. As an option, the annular positioning member and the connecting arm are an integrally formed structure. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] Combination Figures 1 to 3A headset includes a host 10 and an ear hook 20, wherein the ear hook is fixedly provided with an annular positioning member 30, and the host is connected with an embedded member 40, which is matched in the annular positioning member, and the outer side of the embedded member and the inner side of the annular positioning member are matched to design a positioning structure.

[0025] The ear hook 20 is hung on the ear. If the sound hole of the host 10 is not aligned with the ear hole of the user, the user can drive the host 10 to rotate it to a suitable position relative to the ear hook 20, so that the user can effectively receive sound.

[0026] When the host 10 rotates relative to the ear hook 20, the host 10 drives the embedded component 40 to rotate in the annular positioning component 30. The positioning structure designed in cooperation with the embedded component 40 and the annular positioning component 30 can keep the host 10 in the position after rotation. The positioning structure temporarily locks the relative position of the host 10 and the ear hook 20. The user rotates the host 10 with force to release the lock.

[0027] Combination Figure 2 , Figure 5 The positioning structure includes a toothed structure 31 arranged on the inner side of the annular positioning member, and a positioning protrusion 41 arranged on the outer side of the embedded member, and the positioning protrusion can be engaged in the toothed structure.

[0028] Combination Figure 5 , Figure 6 The positioning protrusion 41 is arranged on the arc structure 42 in the circumferential direction of the embedded component. In this way, the positioning protrusion 41 is subjected to force, and the arc structure 42 can be elastically deformed away from or close to the center of the embedded component 40. The elastic deformation of the arc structure 42 can make the positioning protrusion 41 cooperate with the tooth structure 31 to lock the position of the host 10, and can also increase the hand feeling when the user rotates the host 10.

[0029] like Figure 3 , Figure 4 The shaft 43 of the embedded component is positioned on the positioning piece 11 , the positioning piece is provided with a positioning hole 110 that matches the shaft 43 , and the positioning piece is connected to the host 10 .

[0030] The embedded component 40 is connected to the host 10 through the cooperation of the polygonal structure 44 and the polygonal groove 12, and the polygonal structure is arranged on the rotation center line of the embedded component. The polygonal structure 44 is arranged on the embedded component 40, and the polygonal groove 12 is arranged on the host 10. The cooperation of the polygonal structure 44 and the polygonal groove 12 can enable the host 10 to drive the embedded component 40 to rotate synchronously.

[0031] The annular positioning member 30 is fixedly connected to the ear hook 20 via a connecting arm 32, and the annular positioning member 30 and the connecting arm 32 are an integrally formed structure. The connecting arm 32 is inserted at one end of the ear hook 20 and fixed by a locking screw.
