[0002] Headphones are a kind of sound transmission device that converts the electrical signal output by the sound source into sound that can be heard by the human ear through the principle of electroacoustic conversion. According to the wearing method of headphones, they are mainly divided into earplug type, ear-hanging type, in-ear type and headphone. Earplug type and in-ear headphones are easy to cause discomfort to the user's ears. Ear-hanging type is not suitable for users who match their eyes. Headphones have a wide range of applicability. Most users have two main requirements for the use of headphones: 1. Since the distance from the ear to the top of the head of each user is different, the position of the speaker arm needs to be extended to meet the wearing comfort requirements of each user. 2. In ergonomics, the ear has a certain angle relative to the head. In order for the headset to fit the user's ear, the speaker part needs to be able to swing to a certain amplitude. Existing headphones can meet the first requirement mentioned above, and can also meet the second requirement mentioned above, but few can meet both the first and second requirements.

[0003] To this end, the applicant believes that it is necessary to provide a headset that can simultaneously meet the first and second requirements mentioned above. Utility Model Content

[0016] The technical solution of the utility model firstly movably installs a connecting arm on the speaker, one end of the connecting arm is in the speaker, and the other end is exposed outside, and the connecting arm can move between a position where the end exposed outside is close to the speaker and a position away from the speaker, and the movement of the speaker relative to the connecting arm is limited by a first positioning structure, and a pivot groove is provided at the end of the ear band, and the end of the connecting arm is rotatably installed in the pivot groove, so that the speaker can swing relative to the ear band, and the speaker is limited to swing relative to the ear band by a second positioning structure. Compared with the traditional one, the utility model can adjust the position between the speaker and the top of the head, and can swing the speaker within a certain range, and the overall structure is simple, which effectively meets the wearing comfort requirements of the user.

[0017] Specifically, the end of the ear strap 1 is detachably locked with a cover body 12 by means of screws, and the pivot groove 11 is formed on the cover body 12 .

[0018] Specifically, the end of the connecting arm 3 exposed to the outside is inserted with a rotating shaft 4, and the pivoting groove 11 has two opposite side walls respectively inserted with the two ends of the rotating shaft 4 so that the connecting arm 3 can be pivotally assembled to the earband 1.

[0019] Specifically, the connecting arm 3 is made of metal or plastic.

[0020] Specifically, the connecting arm 3 is provided with a limiting groove 31 extending along the length direction of the connecting arm 3, and the speaker 2 is formed with a limiting portion 21 that can extend into the limiting groove 31 at the position corresponding to the limiting groove 31. The limiting portion 21 cooperates with the limiting groove 31 to prevent the connecting arm 3 from completely separating from the speaker 2.

[0021] Specifically, the first positioning structure includes an elastic member 32, and the elastic member 32 is arranged at a position of the connecting arm 3 corresponding to the position inside the speaker 2. A plurality of latching positions 22 are arranged inside the speaker 2, and the plurality of latching positions 22 are spaced apart along the length direction of the connecting arm 3. The latching positions 22 can move between positions elastically counteracting and offsetting the elastic member 32 with the movement of the speaker 2. When the elastic member 32 and the latching positions 22 are elastically counteracted and there is no external force interference, the speaker 2 is restricted and cannot move; applying a certain force to the speaker 2 can force the elastic member 32 to deform and offset from the latching positions 22, so that the speaker 2 can move.

[0022] Specifically, the second positioning structure includes a clamping portion 14 directly or indirectly arranged in the pivot groove 11, and a clamping slot 131 suitable for the clamping portion 14 is formed on one side of the connecting arm 3. The clamping slot 131 can move between the position of engagement and offset with the clamping portion 14 as the connecting arm 3 swings.

[0023] Specifically, a reinforcing arm 13 is disposed on one side of the connecting arm 3 , and the clamping groove 131 is formed on the reinforcing arm 13 to strengthen the structural strength of the connecting arm 3 .

[0024] Specifically, when the clamping portion 14 is indirectly provided in the pivoting slot 11, a sheet member 15 is further provided, and the cover body 12 covers the sheet member 15. The sheet member 15 is respectively bent to form a first bending portion 151 with a local protrusion and a bending portion through which the end of the rotating shaft 4 can pass. The end of the rotating shaft 4 is inserted into the side wall of the pivoting slot 11 after passing through the second bending portion. The first bending portion 151 extends into the pivoting slot 11. The local protrusion is the clamping portion 14. When the external force forces the connecting arm 3 to swing, the cooperation between the clamping portion 14 and the slot 131 causes the deformation portion to be deformed in a direction away from the slot 131, so that the slot 131 and the clamping portion 14 can be smoothly staggered. When the clamping portion 14 is located in the slot 131 and there is no external force interference, the connecting arm 3 is restricted and cannot swing; applying a certain force to the connecting arm 3 can force the clamping portion 14 and the slot 131 to stagger so that the connecting arm 3 can swing.

[0025] The above description is only a preferred embodiment of the utility model, and does not limit the patent scope of the utility model. All equivalent structural changes made by using the contents of the utility model specification and drawings under the utility model concept, or directly / indirectly used in other related technical fields are included in the patent protection scope of the utility model.
