[0025] As shown in Figures 1-3, a battery-detachable headset includes an earphone assembly 100 and a battery assembly 200, wherein the earphone assembly 100 and the battery assembly 200 are detachably connected via a magnetic conductive assembly 300. The magnetic conductive assembly 300 includes an earphone terminal and a battery terminal; both include a fixed plastic component 310, a magnet 320, and a conductive metal component 330; the fixed plastic component 310 is coated on the magnet 320.

[0026] The conductive metal member 330 is disposed in the fixed plastic member 310 and is exposed at the contact surface between the earphone terminal and the battery terminal. The two conductive metal members 330 are conductive when the earphone terminal and the battery terminal are in contact.

[0027] One of the conductive metal parts at the battery end or the earphone end is a contact type 330a, and the other is a plane contact type 330b. The two can also stably conduct electricity when they rotate relative to each other.

[0028] Two different forms of conductive metal parts are used, one is contact type and the other is plane contact type. Compared with the traditional connection method where both are contacts, it does not require strict angle control and can achieve conduction at any position within a certain range, making it more convenient to use. Due to its simple structure, it is also easier to achieve sealing and has better stability.

[0029] Furthermore, the earphone end and battery end of the magnetic conductive component 300 also include a fixed plastic sheet 340, and the fixed plastic sheet 340 is used to fix the conductive metal part 330 and fix the conductive metal part 330 to the conductive part 100 and the battery component 200.

[0030] Furthermore, the conductive metal member 330 of the contact type 330a is a V-shaped spring with a foot 331 provided at the end;

[0031] The fixed plastic part 310 is provided with a plurality of protrusions 311 , which pass through the fixed plastic sheet 340 and the legs 331 to fix the conductive metal part 330 ;

[0032] The V-shaped portion of the conductive metal member 330 passes through the hole 312 on the fixed plastic member 310 and is exposed on opposite surfaces of the two magnetic conductive components 300 .

[0033] Furthermore, the conductive metal member of the plane contact type 330b is a T-shaped member, which is embedded in the fixed plastic member 310. The larger end of the conductive metal member 330, i.e., the head of the T, is exposed outside the fixed plastic member 310 and is used to contact the conductive metal member 330 on another magnetic conductive component 300, i.e., contact the contact type 330a.

[0034] The smaller end of the conductive metal member 330 , namely the T-shaped leg, cooperates with the fixed plastic sheet 340 , and the distal end protrudes from the fixed plastic sheet 340 for conducting electricity with the battery 400 .

[0035] Furthermore, the earphone assembly 100 is of an in-ear type, a semi-in-ear type or an ear-hook type.

[0036] Furthermore, the battery assembly 200 also includes a shell 210, and the battery 400 is disposed in the shell 210. The magnetic conductive component 300 at the battery end cooperates with the opening of the shell 210 to seal the battery 400 in the shell 210.

[0037] Furthermore, there is a limiting protrusion 350 on the magnetic conductive component 300 of the battery assembly 200. Correspondingly, a limiting groove 110 is provided at the contact portion between the earphone assembly 100 and the battery assembly 200. The limiting protrusion 350 cooperates with the limiting groove 110. The width of the limiting groove 110 is greater than the limiting protrusion 350, so that the battery assembly 200 can rotate within a certain range after being combined with the earphone assembly 100. Its function is to limit the conductive metal part 330 of the plane contact type 330b to always maintain contact with the conductive metal part 330 of the contact point type 330a; in addition, it can also play an anti-mistake role.

[0038] The above is only a preferred specific implementation method of the present application, but the scope of protection of the present application is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes based on the technical solution and application concept of the present application within the technical scope disclosed in the present application, and they should be covered by the scope of protection of the present application.
