[0028] See Figure 1 The present invention relates to an adjustable headphone, which consists of an arc-shaped headband 1 and headphone bodies 2 respectively disposed on both sides of the arc-shaped headband 1. The headphone bodies 2 are used to fit with the human ear to provide sound, and the arc-shaped headband 1 is elastic and can clamp and fix the headphone bodies 2 on both sides to the human ear.

[0029] See Figures 1-4To facilitate adjustment of the headphone body 2 and for easy storage, an adjustment component 3 is provided between the arc-shaped headband 1 and the headphone body 2. The adjustment component 3 includes a first rod 31 and a second rod 32 that are hinged to each other. The end of the arc-shaped headband 1 is provided with a first connecting slot 11 that is adapted to the first rod 31. The first rod 31 is axially movable in the first connecting slot 11. The outer wall of the second rod 32 is provided with an arc-shaped groove 33 that is radially opened along its outer wall. The headphone body 2 is provided with a second slot 21 that is adapted to the second rod 32. The second slot 21 is provided with a connecting pin 211 for slidingly engaging with the arc-shaped groove 33. In this embodiment, the headphone body 2 has multiple adjustment modes. By controlling the first rod 31 to slide along the first connecting slot 11, the extension length of the headphone body 2 can be controlled to meet the needs of various head sizes. The first rod 31 and the second rod 32 are hinged together, allowing the headphone body 2 to be flipped away from or closer to the center of the arc-shaped headband 1 around the hinge position. When storage is required, the headphone body 2 can be flipped to a position close to the arc-shaped headband 1 to reduce its volume and facilitate storage. The headphone body 2 can be rotated around the axis of the second rod 32 by cooperating with the second slot 21, making it easy to adjust the angle of the headphone body 2. The headphone of this application has multiple adjustment modes, which can meet various different usage needs and is easy to store.

[0030] See Figure 1 , Figure 2 To facilitate indicating the extension position of the first rods 31 on both sides, the surface of the first rod 31 is provided with an indicator scale 311 arranged along its axial direction. The arc-shaped headband 1 is provided with an indicator area 12 adapted to the indicator scale 311. By observing the indicator scale 311 displayed at the indicator area 12, the extension length of the first rod 31 can be easily indicated, and the relative position of the earphone body 2 and the arc-shaped headband 1 can be easily indicated, making it more convenient to use.

[0031] Example 2:

[0032] See Figure 5 , Figure 6 Based on Embodiment 1, to address the issue of existing headphones compressing the temples of glasses and affecting comfort for users who wear glasses, a ring-shaped soft pad 4 is provided on the side of the headphone body 2 closest to the user. The ring-shaped soft pad 4 has a hollowed-out design at its center to fit the human ear. The headphone body 2 also features a tightening mechanism that engages with the ring-shaped soft pad 4. This tightening mechanism compresses a portion of the ring-shaped soft pad 4 to create a channel for the temples of the glasses to pass through. When the user wears glasses, to prevent the ring-shaped soft pad 4 from compressing the temples and affecting comfort and user experience, the tightening mechanism compresses the ring-shaped soft pad 4, creating a groove that serves as the channel for the temples of the glasses to pass through.

[0033] See Figure 5 , Figure 7 , Figure 8 The tightening mechanism includes a tightening band 5 and a winding member 6 for winding the tightening band 5. The winding member 6 is rotatably disposed on the outside of the earphone body 2. One end of the tightening band 5 is wound around the winding member 6, and the other end passes over one side of the annular soft pad 4 and is fixedly connected to the middle of the earphone body 2. By controlling the winding of the tightening band 5 through the winding member 6, the annular soft pad 4 at the contact position with the tightening band 5 can be compressed. The control is convenient. When the user is not wearing glasses, the tightening band 5 can be unwound through the winding member 6 to restore the annular soft pad 4 to its original shape.

[0034] See Figure 5 , Figure 7 , Figure 8 Specifically, the winding component 6 includes a winding reel 61 and a control panel 62 coaxially arranged with the winding reel 61 and operated by a person. The winding component 6 is located inside the headphone body 2, and one side of the control panel 62 extends outside the headphone body 2. The headphone body 2 is provided with a slot 101 for the tightening strap 5 to pass through.

[0035] To achieve positioning of the take-up member 6, a braking component is also included, which engages with the take-up member 6. The braking component includes a brake disc 7 located on one side of the take-up member 6 and an elastic element 8 for driving the take-up member 6 to move closer to the brake disc 7. The take-up member 6 and the brake disc 7 are respectively provided with a plurality of hemispherical protrusions 63 and hemispherical grooves 71 arranged in a circular array. When the hemispherical protrusions 63 and hemispherical grooves 71 engage, they can limit the relative rotation of the two without external force. When the controller applies external force to the control disc 62, the hemispherical protrusions 63 and hemispherical grooves 71 can be driven to separate, and the take-up member 6 can rotate freely to take up and unwind. After the control disc 62 is released, the take-up member 6 moves towards the brake disc 7 under the action of the elastic element 8, thereby engaging the hemispherical protrusions 63 and hemispherical grooves 71 and locking the two relative to each other.

[0036] Specifically, the tightening mechanism also includes a fixed slide rod 9 fixedly disposed within the headphone body 2, a winding reel 61 slidably disposed on the fixed slide rod 9, and a brake disc 7 and an elastic element 8 respectively disposed at both ends of the fixed slide rod 9.

[0037] The working process of this utility model:

[0038] This utility model discloses an adjustable headphone. During operation, by controlling the first rod 31 to slide along the first connecting slot 11, the extension length of the headphone body 2 can be controlled to meet the needs of various head sizes. The first rod 31 and the second rod 32 are hinged, allowing the headphone body 2 to be flipped around the hinge position towards or away from the center of the arc-shaped headband 1. When storage is required, the headphone body 2 can be flipped to a position closer to the arc-shaped headband 1 to reduce its size and facilitate storage. The cooperation between the second rod 32 and the second slot 21 allows the headphone body 2 to rotate around the axis of the second rod 32, facilitating the adjustment of the headphone body 2 angle.
