The first radiator includes a feeding end. The second radiator includes a ground end, and a first slot is formed between the first radiator and the second radiator. The conductive member is connected to the first radiator and the second radiator. The first insulating member is disposed in the first slot. The first radiator, the second radiator, the conductive member, and the first insulating member collectively serve as at least a part of a shell of the earphone module.
