Winder and Bluetooth earphone using winder

Abstract

The invention discloses a winder. The winder comprises a shell, a limiting control mechanism, an assembly printed circuit board, a rotating shaft, a rotary part, a springback part, and a conductive part with a prominent contact; the assembly printed circuit board is positioned at the bottom in the shell; the conductive part, the rotary part and the springback part are sequentially superposed on the assembly printed circuit board; the lower end of the rotating shaft sequentially passes through the springback part, the rotary part, the conductive part and the assembly printed circuit board, andis fixed at the bottom in the shell; the limiting control mechanism is arranged in the shell; positive and negative anodes used for being connected to the earphone line are welded on the conductive part; and a slot for containing the earphone line is arranged at the circumferential side of the rotary part. The invention further discloses a Bluetooth earphone. By means of the winder and the Bluetooth earphone in the invention, the volume of the winder can be reduced; and furthermore, the bracing force and length can be controlled.

Description

Technical field [0001] The invention belongs to the technical field of earphones, and particularly relates to a cable winder and a Bluetooth earphone using the same. Background technique [0002] At present, wired headsets and stereo Bluetooth headsets on the market inevitably have the entanglement of the headset cord. Due to the limitation of the cord, when using the headset, you must first arrange the cord before using it. There is no existing technology that automatically retracts the cord when not in use. Plan up. [0003] In the prior art, the winding machine adopts a gear belt motor, which is too complicated in structure, high in cost, and requires a large volume space, which cannot meet the requirements of a small earphone. At the same time, the motor also has unstable factors of electrical performance. [0004] There is also a clockwork type winder, but it is too large or not integrated, and cannot meet the design requirements of the headset. Summary of the invention [0005...

AI Technical Summary

Problems solved by technology

[0003] In the existing technology, the winding machine uses a geared motor, which is too complicated in structure, high in cost, and requires a large volume and space, which cannot meet the small size of the earphone. At the same time, the motor also has unstable factors in electrical performance.

[0004] There is also a clockwork winder, but it is too bulky, or not integrated, and cannot meet the design requirements of the earphone
