This corresponds to disposing the elastic member 30 outside the first housing 21, and the elastic member 30 can be prevented from occupying the space in the first housing 21 in which the circuit device is disposed. In addition, in order to ensure that the second housing 22 can better cover the user's ear, the second housing 22 needs to be sized larger. By providing the second housing 22 in the mounting groove 221, the space of the second housing 22 can be fully utilized, which is beneficial to improving the space utilization rate of the ear housing part 20 and improving the structure compactness of the ear housing part 20. In addition, in an embodiment, an offset groove may be provided on the mounting surface 213, so that the elastic element 30 is at least partially disposed in the offset groove to reduce the thickness of the ear shell portion 20 along the arrangement direction of the first shell 21 and the second shell 22.

Specifically, the opening direction of the card slot 223 is substantially perpendicular to the arrangement direction of the two ear shell portions 20, the card slot 223 extends in an arc shape along the circumferential direction of the second housing 22, and the axis of the card slot 223 is substantially overlapped with the rotation axis of the second housing 22. The clip 212 includes a connecting portion connected to the first housing 21 and extending along the arrangement direction of the two ear shell portions 20, and a clip convex portion provided on the connecting portion and protruding toward a side of the clip convex portion. The clamping convex part can be clamped in the clamping groove 223 and can abut against the side wall of the clamping groove 223, so that the second shell 22 is limited to move relative to the first shell 21 along the arrangement direction of the two earphone parts 20. The length of draw-in groove 223 is greater than the length of joint convex part to when guaranteeing joint convex part joint in draw-in groove 223, the joint convex part can slide at draw-in groove 223, thereby makes second casing 22 can rotate with first casing 21 and be connected. With the arrangement, the first shell 21 and the second shell 22 can be connected while the first shell 21 and the second shell 22 are rotationally connected, and the first shell 21 and the second shell 22 are prevented from being separated from each other.

In an embodiment, the locking groove 223 is disposed on a groove wall of the mounting groove 221, and the fasteners 212 and the elastic component 30 are arranged at intervals along a circumferential direction of the first housing 21 to avoid interference between the fasteners 212 and the elastic component 30, which is equivalent to concentratedly disposing the fasteners 212 and the elastic component 30, thereby facilitating improvement of space utilization between the first housing 21 and the second housing 22 and improvement of structural compactness of the ear shell portion 20.

In addition, in order to avoid the interference between the elastic member 30 and the locking groove 223, in an embodiment, the locking groove 212 and the elastic member 30 are arranged at intervals along the extending direction of the rotation axis of the second housing 22, so that the locking groove 223 on the groove wall of the mounting groove 221 and the annular peripheral wall 222 are arranged at intervals along the extending direction of the rotation axis of the second housing 22, and thus, even if the rotation angle of the first housing 21 and the second housing 22 is too large, the interference between the elastic member 30 and the locking groove 223 can be avoided. In another embodiment, a portion of the mounting groove 221 may be used as the annular peripheral wall 222, that is, the annular peripheral wall 222 is in a segment shape, and the locking grooves 223 and the annular peripheral wall 222 are arranged at intervals along the circumferential direction of the mounting groove 221.

In order to improve the connection stability of the first housing 21 and the second housing 22, in an embodiment, the number of the buckles 212 is multiple, and the multiple buckles 212 are uniformly arranged along the circumferential direction of the first housing 21, so that the second housing 22 is uniformly stressed along all parts of the circumferential direction. The clamping grooves 223 may extend in the circumferential direction of the mounting groove 221 in a circular ring shape, or the number of the clamping grooves 223 is also multiple, and the plurality of clamping grooves 223 correspond to the plurality of buckles 212 one to one.

In one embodiment, the slot 223 has two opposite limiting walls 2231, the two limiting walls 2231 are arranged along the length direction of the slot 223, and the clip 212 can move along the length direction of the slot 223 to abut against the limiting walls 2231. That is, the rotation angle of the second housing 22 with respect to the first housing 21 is limited, and the rotation angle of the second housing 22 is less than 360 °. This can prevent the second housing 22 from rotating at an excessive angle to damage the connection circuit with the first housing 21. For example, when one side of the clip 212 abuts against one of the limiting walls 2231, a central angle corresponding to an arc length between the other opposite side of the clip 212 and the other limiting wall 2231 is a maximum rotation angle of the second housing 22. The maximum rotation angle of the second housing 22 can be flexibly set in a range of more than 0 ° and less than 360 ° according to actual conditions.

In addition, in one embodiment, the headset has an initial state that can be used by a portion or a plurality of users, i.e., in the initial state, the headset can be used by the portion or the plurality of users without adjusting the second housing 22. In this initial state, the two limiting walls 2231 of the engaging groove 223 are spaced from the buckle 212, so that the user can rotate the second housing 22 in the counterclockwise direction or in the clockwise direction when the user needs to adjust the relative position between the head-mounted portion 10 and the second housing 22. In other words, when the user wears the headphone, the head mount 10 may be adjusted toward the front side of the user or may be adjusted toward the rear side of the user. The adaptability of the headset is improved, and the adjustment and the use of the headset by a user are facilitated. Wherein, the angle of the second housing 22 rotating in the counterclockwise direction may be smaller than, equal to, or larger than the angle of the second housing 22 rotating in the clockwise direction.

In one embodiment, the second housing 22 is rotated by an angle greater than or equal to 10 ° with respect to the first housing 21. I.e., the maximum angle of rotation of the second housing 22 is greater than or equal to 10 deg., as will be appreciated. The larger the rotation angle of the second housing 22, the larger the adjustment range of the head set 10 and the second housing 22, and the stronger the ability of the headset to adapt to different user requirements. In an embodiment, the rotation angle of the second housing 22 relative to the first housing 21 is 20 °, and when the headset is in the initial state, the second housing 22 can rotate 10 ° counterclockwise or 10 ° clockwise, which can meet the requirement of most users, and can also avoid the situation that the connection circuit between the second housing 22 and the first housing 21 is broken or damaged due to an excessively large rotation angle of the second housing 22. Of course, the rotation angle of the second casing 22 with respect to the first casing 21 is not limited thereto, and the rotation angle of the second casing 22 may also be 10 °, 20 °, 30 °, 40 °, or 60 °, or the like.

In one embodiment, the number of the elastic elements 30 is multiple, and the elastic elements 30 are arranged at intervals along the circumference of the second housing 22. Specifically, the elastic assemblies 30 are arranged along the circumferential direction of the annular circumferential wall 222 at intervals, so that the circumferential directions of the second shell 22 and the first shell 21 are uniformly stressed, and the rotation stability and the rotation effect of the second shell 22 are improved. In order to further ensure uniform stress on the second shell 22 and the first shell 21 in the circumferential direction, a plurality of elastic assemblies 30 are uniformly spaced along the circumferential direction of the second shell 22. For example, in one embodiment, the number of the elastic assemblies 30 is two, and the two elastic assemblies 30 are uniformly arranged along the circumferential direction of the second housing 22. Of course, the number of elastic members 30 may be three or four, etc. In one embodiment, the plurality of snaps 212 and the plurality of elastic members 30 are alternately arranged in sequence along the circumference of the second housing 22. For example, the number of the snaps 212 is two, the number of the elastic assemblies 30 is two, the two snaps 212 and the two elastic assemblies 30 are alternately arranged in sequence along the circumferential direction of the second housing 22, and the two snaps 212 are uniformly arranged along the circumferential direction of the first housing 21. Of course, the number of the buckles 212 can be three or four, and the like.
