Into the reel, at the same time, the headphone cord 12 in the reel can not be loose.

In this embodiment, the shape of the first roller 3 and the second roller 14 may be set to be a circular axis or a semi-circular axis. It is of course to be understood that the specific shapes of the first roller 13 and the second roller 14 are not limited in this embodiment.

Referring to FIG. 2, a schematic structural view of the first roller and the second roller is shown (the first roller 13 and the second roller 14 have the same structure), and FIG. 3 is a cross-sectional view of FIG. 2, in which 1301 is a circular axis. The two ends of the circular shaft 1301 are respectively fixed on the casings 5 and 16, and there is a gap 302 between the roller 1303 and the circular shaft 1301, and the roller 1303 is rotatable relative to the circular axis 30.

When assembled, the two ends of the circular shaft 1301 are respectively fixed to the housings 15 and 16 (as shown in Fig. 1), and when the headphone cord 12 is retracted or pulled, the roller 1303 is rotated along with the headphone cord 12.

FIG. 4 is a schematic structural diagram of a headphone wire take-up device according to an embodiment of the present invention. The earphone wire take-up device includes: a housing, a reel set in the housing, and a driving device for driving the reel And a clutch device disposed between the driving device 1 and the reel, the earphone retracting device further comprising: a first roller 13 disposed in the housing;

The second roller 14 is disposed in the casing, and a gap is formed between the second roller 14 and the first roller 13. The earphone wire 12 can pass through the slit, and when the earphone wire 12 is retracted or pulled, the earphone wire 12 can drive the first The roller 13 and the second roller 14 rotate.

As shown in FIG. 4, the earphone cord take-up device further includes: a shifting device (composed of a plurality of gears) disposed between the driving device 1 and the clutch device.

In the present embodiment, the shifting device is rotated by the gears 2, 3, 4, 5, 6, 7, 8; the gear 8 is at the same time a measuring surface of the reel and connected to the other ft through the central shaft. The baffle plate together constitutes a reel for winding the headphone cable; 1 1 is a plurality of circular tracks of the signal communication device, and is led out to the signal line 9 through the conductive elastic piece or the conductive etched needle 10, in FIG. 2, 15 is the headphone cable take-up device a second gear 6 connected to the reel, the second gear 6 and the first gear 7 are connected by a rotating shaft 7; for controlling the first gear 7 to drive the second gear 6 to rotate or control the first gear 7 and the second gear A separate clutch mechanism is disposed between the first gear 7 and the second gear 6.
