Headband structure and headphones

Abstract

This application relates to a headband structure and a headset. The headset includes a headband structure, which includes an upper shell assembly and a lower shell assembly. The upper shell assembly includes an upper shell connected to the side of the lower shell assembly opposite to its own arc center. The two ends of the side of the upper shell opposite to the lower shell assembly have a first arc-shaped structure. The first arc-shaped structure is a convex arc shape in the width direction of the upper shell assembly. The top of the side of the upper shell opposite to the lower shell assembly has a flat structure. The flat structure extends straight in the width direction of the upper shell assembly to reduce the clamping force of the headband structure. A support strip is installed on the lower shell to support the upper shell, so that more clamping force is provided through the support strip. With the high toughness of the support strip, the clamping force can be adjusted within a large range, thus improving the wearing comfort when the user wears the headset.

Claims

1. A headband structure comprising an upper shell assembly and a lower shell assembly, the upper shell assembly and the lower shell assembly being respectively arcuate strips in their length direction; the upper shell assembly comprising an upper shell connected to the side of the lower shell assembly opposite to its own arcuate center, and the upper shell having a first arcuate structure at both ends on the side opposite to the lower shell assembly, the first arcuate structure being a convex arcuate shape in the width direction of the upper shell assembly, and the top of the side of the upper shell opposite to the lower shell assembly having a planar structure, the planar structure extending straight in the width direction of the upper shell assembly.

2. The headband structure as described in claim 1, wherein, An installation space is formed between the upper shell and the lower shell assembly. A support strip with higher toughness than the upper shell is provided in the installation space. The two ends of the support strip are respectively connected to the two ends of the lower shell assembly.

3. The headband structure as described in claim 1, wherein, The upper shell assembly also includes an upper protective sleeve and an upper elastic strip. The upper protective sleeve covers the side of the upper shell opposite to the lower shell assembly. The upper elastic strip is disposed between the upper protective sleeve and the upper shell, with one side of the upper elastic strip attached to the upper protective sleeve and the other side attached to the upper shell.

4. The headband structure as described in claim 3, wherein, The upper elastic strip includes a first elastic strip and a second elastic strip that are attached to each other. The hardness of the first elastic strip is less than that of the second elastic strip. The first elastic strip is attached to the upper protective sleeve on the side opposite to the upper shell, and the second elastic strip is attached to the upper shell on the side opposite to the first elastic strip.

5. The headband structure as described in claim 4, wherein, The length of the first elastic strip is greater than the length of the second elastic strip, and the two ends of the first elastic strip facing the upper shell are respectively attached to the corresponding first arc-shaped structure. The side of the second elastic strip facing the upper shell is attached to the planar structure, and the side of the second elastic strip facing away from the upper shell is flush with the first arc-shaped structure.

6. The headband structure as described in claim 1, wherein, The upper shell has a second arc-shaped structure at both ends facing the lower shell assembly. The second arc-shaped structure is concave to the lower shell assembly in the width direction of the upper shell assembly, so that the second arc-shaped structure and the lower shell assembly form a sliding space for accommodating a slider.

7. The headband structure as described in claim 1, wherein, The lower shell assembly includes a lower shell, a lower protective sleeve, and a lower elastic strip. The lower shell is connected to the upper shell. The lower protective sleeve covers the side of the lower shell opposite to the upper shell. The lower elastic strip is disposed between the lower protective sleeve and the lower shell, with one side of the lower elastic strip attached to the lower shell and the other side attached to the lower protective sleeve.

8. The headband structure as described in claim 7, wherein, The lower elastic strip includes a third elastic strip and a fourth elastic strip that are attached to each other. The length of the third elastic strip is shorter than that of the fourth elastic strip, and the hardness of the third elastic strip is greater than that of the fourth elastic strip. The side of the third elastic strip opposite to the fourth elastic strip is attached to the lower shell, and the side of the fourth elastic strip opposite to the third elastic strip is attached to the lower protective sleeve. The surface of the lower shell attached to the lower protective sleeve is flush with the side of the fourth elastic strip opposite to the third elastic strip.

9. The headband structure as described in claim 7, wherein, The lower shell has a mounting hole at each of its opposite ends, and a guide sleeve is embedded in each mounting hole. The guide sleeve is used for a sliding member to pass through, so that part of the sliding member is exposed in the headband structure.

10. A headset comprising a headband structure as described in any one of claims 1 to 9, wherein each end of the headband structure is provided with a slider movable relative to the headband structure, and each slider is connected to an earcup.
