Description

Technical Field

[0001] This utility model belongs to the field of retractable winding, and particularly relates to a retractable winding device and its earphone. Background Technology

[0002] Currently, headphone products on the market suffer from numerous inconveniences in headphone cable storage. Traditional wired headphone cables are often of fixed length, easily becoming tangled and knotted when not in use. This not only wastes time but can also damage the cable due to frequent pulling, affecting the headphone's lifespan. Some existing cable winding devices have complex designs, are inconvenient to operate, and most can only store a single cable, failing to meet the simultaneous extension and retraction and storage needs of dual headphone cables. This makes them unsuitable for use with two headphones, resulting in a poor user experience. Therefore, there is an urgent need for a device with a simple structure, convenient operation, and the ability to simultaneously extend and retract dual headphone cables to solve the current headphone cable storage problem.

[0007] Preferably, the first telescopic component includes a winding reel, a circuit board, and a retaining ring. The winding reel, circuit board, and retaining ring are all installed between the shaft and the cover plate. The shaft passes through the circuit board, the winding reel, and the retaining ring in sequence. The retaining ring cooperates with the limiting hole.

[0008] A retractable earphone includes a first earphone, a first earphone cable, a second earphone, a second earphone cable, a housing, a battery, buttons mounted on a motherboard, a charging port mounted on the motherboard, the motherboard, and a retractable winding device.

[0009] The beneficial effects of this utility model are: Achieving simultaneous extension and retraction of dual headphone cables: This retractable winding device, by setting up a first telescopic component and a second telescopic component with identical structures, can respectively store the first headphone cable and the second headphone cable, realizing independent extension and retraction and simultaneous storage of dual headphone cables, effectively avoiding headphone cables from getting tangled and knotted, and improving ease of use; Simple structure and strong stability: The device adopts a telescopic shell composed of cover plate, shaft and other components, and is equipped with telescopic components such as winding disc and retaining ring. The overall structure is compact and the components are connected by shaft column through, retaining block and mounting hole, etc., which makes the installation firm and the operation stable, and can effectively extend the service life of the device. Highly adaptable and widely applicable: This winding device can be directly integrated into headphone products to form retractable headphones.
