An earphone wire take-up device and an earphone using the wire take-up device

Abstract

The invention relates to an earphone wire take-up device and an earphone using the wire take-up device. The earphone wire take-up device includes a disc-shaped upper cover, a disc-shaped lower cover, a spring seat, and a scroll spring, and a central column is arranged in the center of the lower cover; The spring seat is arranged in a ring shape; the earphone cable take-up also includes a stop cover for preventing the spring seat from freely rotating, the earphone cable take-up also includes a scroll spring cover and a slide block that can slide and reset, and the tail of the slide block is set There is a pressing part for pressing the wire; the lower side of the scroll spring cover is provided with a chute suitable for sliding the slider; the center of the scroll spring cover is provided with a center hole suitable for the passage of the center column; Including the slider gland, the center of the slider gland is provided with a central hole suitable for the passage of the center column; automatic winding is realized through the cooperation of the spring seat and the scroll spring; through the cooperation of the slider and the spring seat, it can effectively control The pull-out length of the wire can be flexibly adjusted according to the needs of use.

Description

technical field [0001] The invention relates to the technical field of communication equipment, in particular to an earphone cable retractor and an earphone using the cable retractor. Background technique [0002] At present, the earphones commonly used by people all use longer earphone wires to connect the sound source to the earphones. The disadvantage is that when the earphones are not used, the longer earphone wires are piled up and entangled with each other. The entangled earphone wires are sorted out. For this reason, people have designed and produced earphones with a take-up box, so that when the earphones are not in use, the earphone wires can be put into the take-up box, which solves the problem of long earphones when the earphones are not in use. The problem that the wires are piled up and entangled with each other, taking the Chinese patent ZL200620060847.X as an example, this patent discloses a cable take-up box for earphones, such as figure 1 Shown, comprise ba...

AI Technical Summary

Problems solved by technology

The marble moves between the annular groove and the rectangular groove. When it moves to the connecting part, the marble is stuck, and the limit plate 13 is rotated again to make the marble move into the adjacent annular groove. The marble always moves along the rectangular groove. The groove reciprocates; this kind of earphone with a wire take-up box also has obvious shortcomings. When in use, the length of the outgoing line can only be controlled according to the diameter of the annular groove, and the length of the earphone line cannot be adjusted to any appropriate length according to the needs. After staying, you need to pull the earphone cable out and release it to reset the spring 14, which will easily cause the earphone cable to be deformed or even broken, which will affect the service life of the earphone cable

Other headphone cable winding tools such as fishbone winders and buckle winders are cumbersome to operate, and the length of the wire cannot be flexibly adjusted during use, which makes it inconvenient to use
