A cord winding module, comprising a rotary wheel () on which a cord () is wound and a stop button () working cooperatively with the rotary wheel. The cord winding module further comprises a spring wire () working cooperatively with the stop button as an elastic support device, and the stop button automatically brakes the rotary wheel under the action of the elastic force of the spring wire and prevents the rotary wheel from retracting the cord. The spring wire has an arc shape, or exhibits an arc shape when pre-pressed and deformed by the stop button.

Cord winding module

A magnetic attraction type cord winding module, comprising a rotary wheel () on which a cord () is wound and a stop button () working cooperatively with the rotary wheel (). The cord winding module further comprises at least one pair of magnet blocks, and the at least one pair of magnet blocks comprise a first magnet () disposed on the stop button () and a second magnet () disposed on the rotary wheel (). The stop button () automatically brakes the rotary wheel () under the action of an attractive force or a repulsive force of the magnet blocks and prevents the rotary wheel () from retracting the cord (). The magnet block disposed on the stop button () does not protrude from the upper surface of the stop button (), and the magnet block disposed on the rotary wheel () is flattened.

Pull-out type cord winding module

A pull-out type cord winding module, comprising a rotary wheel () which a cord () is wound on and which is connected with a coil spring (), and a stopper mechanism working cooperatively with the rotary wheel () and including a functional rail, a ball () and a rolling assisting device. The functional rail comprises a locking rail, a communicating rail () and annular rails () which are connected, groove-shaped and arranged around an outer circumference of the rotary wheel (). A guide groove () is provided on the rolling assisting device, and two ends of the guide groove () are located at the upper and lower sides of the outer circumference of the rotary wheel () respectively. The guide groove () cooperates with the functional rail to hold the ball (). When the rotary wheel () rotates, the ball () rolls in the functional rail to lock or unlock rotation of the rotary wheel ().

A dual wireless earphones comprise two earphone bodies and a connecting cable assembly. The connecting cable assembly comprises a cable tube and two connectors fixedly connected to both ends of the cable tube respectively, one of the connectors is detachably connected to one of the earphone bodies, and the other connector is detachably connected to the other earphone body. In the dual wireless earphones according to the present disclosure, two earphone bodies are detachably connected by a connecting cable assembly, and when the dual wireless earphones are used, the two earphone bodies can be connected by the connecting cable assembly, thereby effectively avoiding the earphone bodies being dropped and lost when they are worn. Moreover, the user can choose whether to connect the two earphone bodies according to his preferences and usage scenarios, so the use of the dual wireless earphones is greatly facilitated.
