Earphone capable of enhancing low-frequency characteristic

Abstract

The invention discloses an earphone capable of enhancing a low-frequency characteristic. The earphone comprises an earphone plug, in-ear sound-generating parts and an earphone cable connecting the earphone plug and the in-ear sound generating parts. Each in-ear sound-generating part comprises a shell, a loudspeaker single-body, an earphone rear cavity and an extension tube which is communicated with the rear cavity and accommodates the earphone cable. The earphone cable is fixed in the extension tube via a fixing component. The extension tube is internally provided with a low-frequency enhanced sound-guiding tube which is consistent with the extension direction of the extension tube. The rear cavity and the external space of the earphone are communicated via the sound-guiding tube. The earphone cable is provided with zipper teeth which are provided with a zipper head which can be matched with the zipper teeth in use. The zipper teeth are engaged with each other or separated via the zipper head. The low-frequency characteristic of the earphone is enhanced via changing the cavity structure of the earphone so that low-frequency performance of the earphone is obviously enhanced, the low-frequency sound effect of the earphone is enhanced, a phenomenon of winding of the earphone cable is also effectively avoided and thus the service life of the earphone is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of electronic products, in particular to an earphone capable of improving low-frequency characteristics. Background technique [0002] Mid-to-high-end earphones with call function and music appreciation function or only music appreciation function are widely used. While making calls convenient, they can also enjoy high-quality music brought by music software. Users hope that the headset can be used to reproduce various realistic and shocking music effects while having a good call function. Non-enclosed earphones are favored by more and more mobile phone manufacturers and users due to their small size, easy portability, high cost performance, and convenient use with main equipment. However, due to the limitation of its size, there are also certain restrictions on the size of the speaker unit used, and the diameter of the speaker unit is generally between 6mm and 18mm. The small speaker size limits the low-f...

Problems solved by technology

[0003] And usually the earphone wires of the earphones are long, and people tend to roll up the earphone wires and put them in the pockets of their clothes, so that the earphone wires are entangled together, which is prone to knotting, and it will take a long time to sort out the earphones when they are used next time. The headphone cable has brought inconvenience to people

And because the copper wire in the earphone cable is relatively thin, it will shorten the service life of the earphone after being wound many times.
