[0042] An embodiment of the present utility model provides a head-mounted earphone 100, the purpose of which is to solve the problem of poor comfort existing in the head-mounted earphone 100 in the related art.

[0043] Referring to Figure 1-7 As shown, for the above purpose, the head-mounted earphone 100 provided by the embodiment of the present utility model includes a headband 10, earphone parts 20, and a connection assembly 30. Among them, the number of the earphone parts 20 is two, and they are respectively connected to both ends of the headband 10. At least one earphone part 20 can rotate relative to the headband 10 between a normal position and a relief position; the connection assembly 30 includes a housing 31, a slider 32, and a connecting rod 33. The housing 31 is provided on the headband 10, and a slider 32 is provided corresponding to the rotatable earphone part 20. The slider 32 is provided in the housing 31 and has a first state and a second state that can be switched with each other. The connecting rod 33 has a first end and a second end that are opposite to each other. The first end extends out of the housing 31 and is connected to the slider 32, and the second end is connected to the earphone part 20 at the corresponding position. When the slider 32 is in the first state, the earphone is in the normal position, and when the slider 32 is in the second state, the earphone is in the relief position.

[0044] Specifically, the headband 10 is arranged in a U shape and is specifically used to fit with the user's head to wear the earphones on the head. The number of the earphone parts 20 is two, and they are respectively connected to both ends of the headband 10. The earphone parts 20 are used to cover the outer sides of the user's ears and transmit audio to the user. In this embodiment, at least one earphone part 20 is hingedly connected to the headband 10 through a pin shaft, so that the earphone part 20 can rotate relative to the pin shaft, and thus can rotate between a normal position and a relief position deflected outward relative to the ear. When the earphone part 20 is in the normal position, the earphone part 20 can cover the outer side of the ear, and thus transmit audio to the ear. When the earphone part 20 is in the relief position, there is a certain angle between the earphone part 20 and the ear, so that a gap can be left to relieve the fatigue of the ear.

[0045] It should be noted that both of the two earphone parts 20 can be set as a rotating structure, or one earphone part 20 is a fixed structure and the other earphone part 20 is a rotating structure. When the earphone part 20 is in the relief position, the earphone part 20 can still be in a working state, that is, it can still output audio externally.

[0046] The connecting component 30 is arranged corresponding to the rotating earphone part 20, that is, a connecting component 30 is provided at each end of the headband 10 corresponding to the connected rotatable earphone part 20. The connecting component 30 includes a housing 31, a slider 32 and a connecting rod 33. The housing 31 is installed on the headband 10, the slider 32 is installed in the housing 31 and has a first state and a second state that can be switched with each other. The first end of the connecting rod 33 is hinged to the slider 32, and the second end is hinged to the earphone part 20. In this way, a rocker-slider 32 mechanism is formed among the headband 10, the slider 32, the connecting rod 33 and the earphone part 20. When the slider 32 switches from the first state to the second state, it can drive the earphone part 20 to rotate, so that the earphone part 20 rotates from the normal position to the relief position. On the contrary, when the earphone part 20 rotates from the relief position to the normal position, the slider 32 can also be switched from the second state to the first state.

[0047] In summary, the head-mounted earphone 100 provided by the present utility model makes the earphone part 20 hinged to the headband 10, sets the connecting component 30 with the slider 32 and the connecting rod 33, and makes the slider 32 have a first state and a second state that can be switched with each other. The first end of the connecting rod 33 is connected to the slider 32, and the second end is connected to the earphone part 20. In this way, a rocker-slider 32 mechanism can be formed among the headband 10, the slider 32, the connecting rod 33 and the earphone part 20, and thus the rotation of the earphone part 20 can be realized by adjusting the position of the slider 32. Furthermore, the earphone part 20 of the head-mounted earphone 100 can rotate a certain angle relative to the ear during use, and there is a certain angle between the earphone part 20 and the ear, so that a gap can be left to relieve the fatigue of the ear.

[0048] In a specific embodiment of the present utility model, a track, a push block 34, and a first elastic member 35 are further provided inside the housing 31. The track includes a first track 315 and a second track 316 arranged in an L shape. The corner position of the track is the first end, the end of the first track 315 is the second end, and the end of the second track 316 is the third end. The slider 32 is slidably installed on the first track 315, the push block 34 is slidably installed on the second track 316, the first elastic member 35 is installed at the second end, and the end is connected to the slider 32. In the first state, the push block 34 is located at the first end, the slider 32 is located at the second end, and the first elastic member 35 is in a compressed state. In the second state, the push block 34 is located at the third end, the first elastic member 35 is reset and pushes the slider 32 to the first end.

[0049] Specifically, when the push block 34 is pushed from the first end to the third end, that is, when the push block 34 no longer occupies the space of the first track 315, the elastic member in the compressed state is reset, and then the slider 32 is pushed to the first end. The slider 32 slides to drive the connecting rod 33 and the earphone part 20, so that the earphone part 20 rotates from the normal position to the relief position. Similarly, when the earphone part 20 is rotated and rotated from the relief position to the normal position, the earphone part 20 can slide the slider 32 from the first end to the second end through the connecting rod 33. At this time, by moving the push block 34 to the first end, the earphone part 20 can be kept in the normal position. In this way, the rotation control of the earphone part 20 can be realized.

[0050] It should be noted that in addition to the above structure, the position of the slider 32 can also be switched through other structures. For example, the position of the slider 32 can be directly switched through a piston cylinder or a lead screw slider 32 mechanism.

[0051] In a specific embodiment of the present utility model, the housing 31 is provided with a first limiting groove 313 parallel to the second track 316. The push block 34 is provided with an adjusting portion that extends from the first limiting groove 313 to the outside of the housing 31. The adjusting portion is adapted to push the push block 34 from the first end to the third end. A second elastic member 36 is further provided inside the housing 31. The second elastic member 36 is installed at the third end, and the second elastic member 36 is used to push the push block 34 from the third end to the first end when resetting.

[0052] Specifically, the slider 32 can be pushed from the first end to the second end through the adjusting portion, so that the push block 34 no longer occupies the space of the first track 315. Since the push block 34 compresses the second elastic member 36 when sliding to the third end, when the slider 32 slides to the second end under the action of the earphone part 20, the compressed second elastic member 36 is reset and can push the push block 34 to the first end, so that the position adjustment of the push block 34 can be realized.

[0053] It should be noted that in addition to the above structure, the position of the push block 34 can also be switched through a piston cylinder or a lead screw slider 32 mechanism.

[0054] In a specific embodiment of the present utility model, the connecting assembly 30 further includes a push block cap 37, and the push block cap 37 covers the adjusting portion. By providing the push block cap 37, the volume of the adjusting portion can be increased by using the push block cap 37, so as to facilitate the user to hold and adjust the push block 34.
