One end of the neck cord 7 is fixed to the rotating base 3 and wound within the second slot 32. The other end of the neck cord 7 extends out of the housing 1 and is in a ring shape.

[0036] In this retractable earphone device 100, the earphone cord 62 and the neck cord 7 are alternately wound around a rotating base 3. Driven by a power element 4, the rotating base 3 rotates to release and retract the earphone cord 62 and the neck cord 7, while the power supply assembly 5 supplies power to the earphone inlet 61. When wearing the earphones, the neck cord 7 is pulled out and looped around the neck, leaving the earphone inlet 61 in direct use. When not in use, the rotating base 3 rotates to retract the neck cord 7 and the earphone cord 62 into the housing 1, making use and storage very convenient and eliminating the need to constantly wear the earphones around the neck.

[0037] See also Figure 2 and Figure 3 In one embodiment of the housing 1, the housing 1 includes a main body 11 and a rear cover 12. The main body 11 is hollow and open at one end. The rear cover 12 is snap-fitted onto the open end of the main body 11 to seal the main body 11. A charging port 16 is provided on the outside of the main body 11 for electrical connection to the power supply assembly 5.

[0038] See also Figure 3 and Figure 4 In one embodiment, the rotating base 3 is cylindrical, and the first groove body 31 and the second groove body 32 are formed by the inward depression of the circumferential outer side of the rotating base 3, and the first groove body 31 and the second groove body 32 are spaced along the axial direction of the rotating base 3 to facilitate the winding of the headphone wire 62 and the neck hanging wire 7 to avoid mutual interference.

[0039] In another embodiment, the power element 4 may be a spring, disposed within the rotating base 3, with one end fixedly connected to the bracket 2 and the other end fixedly connected to the rotating base 3. When the headphone cord 62 and neck strap 7 are pulled out of the housing 1, the rotating base 3 rotates forward, contracting the spring. When storage is required, the spring's elastic restoring force causes the rotating base 3 to rotate in the reverse direction, winding the headphone cord 62 and neck strap 7 within the housing 1, enabling quick and automatic storage.

[0040] See also Figure 5 In addition to the above embodiment, bracket 2 is positioned in the center of the spring. Bracket 2 defines a fixing slot 21 along the axis of rotating base 3, and a retaining slot 33 is provided within rotating base 3. The spring has an inner and outer end radially connected. The inner end engages with fixing slot 21, and the outer end engages with retaining slot 33, ensuring a secure installation of the spring.

[0041] See also Figure 6, considering that the neckline 7 can be quickly positioned after being pulled out, the retractable earphone device 100 also includes a positioning steel ball 8. One side of the rotating base 3 is recessed along the circumference to provide a locking track 34 and at least two runways 35 with different diameters. The two runways 35 are annular and connected to form an inner and outer ring runway 35 structure. The locking track 34 is relatively short, and the locking track 34 is located between the two runways 35 and is connected to the two runways 35 respectively. A guide groove 13 is provided on the inner bottom wall of the shell 1 extending radially, and the positioning steel ball 8 is provided in the guide groove 13, and the positioning steel ball 8 is partially located in the runway 35 or the locking track 34.

[0042] When the neck cord 7 and the headphone cord 62 can be pulled out smoothly, the positioning steel ball 8 can only move along the guide groove 13, and the two runways 35 can slide along the positioning steel ball 8. When the pulling stops, the rotating base 3 rotates in the opposite direction, and the positioning steel ball 8 enters the locking path 34. Because the locking path 34 is short, the positioning steel ball 8 is stuck with the locking path 34, making the rotating base 3 unable to rotate. At this time, the pulled-out length of the neck cord 7 and the headphone cord 62 is locked. When the neck cord 7 and the headphone cord 62 are pulled out again, the rotating base 3 rotates in the forward direction, and the positioning steel ball 8 exits the locking path 34 and continues to enter the runway 35, completing the automatic storage.

[0043] See also Figure 3 To facilitate storage of the earphone assembly 6's in-ear portion 61, a mounting hole 14 is provided on the outer side of the housing 1, into which the earphone assembly 61 can be inserted.
