The invention is further described in connection with the following detailed description, in order to make the technical means, the creation characteristics, the achievement of the purpose and the effect of the invention easy to understand.

As shown in fig. 1 and 2, the sliding conductive headset of the present embodiment includes two headset units 10 arranged on the left and right sides of the split row, a signal processing module, a sound playing module, and the like are provided in the headset units 10, the two headset units 10 are connected by a headband 30, in order to achieve the adjustment of the wearing space between the headband 30 and the headset units 10, a slider 20 is fixedly connected above each headset unit 10, and the end of the slider 20 is inserted into the headband 30 and slidingly engaged with the headband 30, or of course, the end of the headband 30 is inserted into the slider 20 and slidingly engaged with the slider 20, and the embodiment preferably adopts a manner in which the end of the slider 20 is inserted into the headband 30, so that the headband 30 is larger, the slider 20 is smaller, and the wearing comfort is better.

Conduction is achieved between the two earphone units 10 through a conductive unit, as shown in fig. 3 and 4, the conductive unit includes two sliding conductive assemblies respectively located at two ends of the headband 30 and a connecting piece (not shown) located in the middle of the headband 30 and used for conducting the two sliding conductive assemblies, the sliding conductive assemblies include two conductive sliding rails 40 arranged in the headband 30 in parallel and two elastic pieces 50 arranged on the slider 20 corresponding to the two conductive sliding rails 40, and in the sliding track of the slider 20 and the headband 30, the elastic pieces 50 are kept in contact with the conductive sliding rails 40.

The conductive sliding rail 40 is made of copper sheet or other conductive metal sheet, and is embedded or adhered into the headband 30, so that the headband is firmly fixed, and the thickness of the headband can be designed to be relatively thick, so that the elastic sheet 50 can still be conducted with the conductive sliding rail 40 after the elastic sheet 50 repeatedly slides on the conductive sliding rail 40 to cause abrasion of the conductive sliding rail 40. The spring plate 50 is fixed to the slider 20 by a screw, and since the spring plate 50 is easy to replace, it is preferable that the hardness of the conductive rail 40 is higher than that of the spring plate 50 in order to avoid the conductive rail 40 from being worn by the spring plate 50. The connection member may be a connection wire, an FPC board or other conductive member, and in this embodiment, the connection wire is preferably fixed, and the second wire slot 311 into which the connection wire is inserted is formed on the inner peripheral surface of the middle portion of the headband 30 for convenience.

The earphone unit 10 on the right side is a main earphone unit, the earphone unit 10 on the left side is an auxiliary earphone unit, positive and negative two-strand branches of one end of an audio output line 60 fixed on the main earphone unit respectively penetrate through the slider 20 and are welded with the two elastic sheets 50 through spot welding, and the positive and negative two-strand branches of each end of the connecting line are respectively connected with the two conductive sliding rails 40 on the same end of the headband 30.
