Description

Technical Field

[0001] The utility model relates to the technical field of earphones, in particular to an earphone head beam and a head-mounted earphone. Background Art

[0002] A head-mounted earphone, as the name implies, is worn on the head rather than inserted into the ear canal, which is a type of earphone different from in-ear earplugs.

[0003] A head-mounted earphone usually has a head beam. The head beam is worn on the head, and the elasticity of the head beam enables the earphone to cover the ears. Some head-mounted earphones on the market use a single steel bar or steel band as the skeleton to provide elasticity. Since the steel band is single and non-detachable, the elasticity is fixed. For people with a smaller head shape, there may be a problem of discomfort.

[0004] For example, a head-mounted earphone disclosed in Chinese Patent Application No.: CN202220642960.8 has only a single headband steel bar, which is non-detachable at the same time, and the elasticity is fixed. For people with a smaller head shape, there may be a problem of discomfort.

[0005] Another example is a head-mounted earphone disclosed in Chinese Patent Application No.: CN201820488258.4. The sliding steel bar is also non-detachable, and the elasticity is fixed. For people with a smaller head shape, there may be a problem of discomfort. Summary of the Utility Model

[0028] The present application provides a headband for headphones, which includes a headphone bracket 10, a connecting device 20, a first steel band 210, a second steel band 211, and a flexible pad 212; the flexible pad 212 and the first steel band 210 are closely attached together; the connecting device 20 includes a connecting seat 21, an inner cover 25, and an outer cover 26; a first fastener passes through the end of the first steel band 210 and fastens the connecting seat 21 and the inner cover 25 together; the outer cover 26 slidably covers the connecting seat 21, and a connecting port 29 is formed between the outer cover 26 and the connecting seat 21; the end of the second steel band 211 is detachably inserted into the connecting port 29; the headphone bracket 10 is slidably disposed on the connecting seat 21. The first steel band 210 and the second steel band 211 are elastic. The first fastener is preferably a screw. During assembly, the flexible pad 212 and the first steel band 210 are closely attached (e.g., pasted) together, and then the first fastener passes through the connecting seat 21 and the inner cover 25, and the first steel band 210 assembles the three together. The outer cover 26 slidably covers the connecting seat 21, so that a connecting port 29 is formed between the outer cover 26 and the connecting seat 21. The two ends of the second steel band 211 are inserted into the corresponding connecting ports 29 to complete the assembly of the second steel band 211. When the second steel band 211 is not needed, it only needs to be pulled out, which is very convenient. Since the second steel band 211 is detachable, the elasticity can be adjusted to adapt to more users. The headphone bracket 10 includes a frame body 11 and a connecting frame 16.

[0029] Preferably, a first sliding groove 22 is provided on the inner side of the connecting seat 21; a U-shaped portion 12 is formed on the frame body 11 of the headphone bracket 10, and the U-shaped portion 12 slides in the first sliding groove 22. The U-shaped portion 12 of the frame body 11 can slide more smoothly in the first sliding groove 22.
