[0020] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0021] like Figures 1 to 4As shown, a retractable clip-on earphone comprises an outer ear component compartment 1, an inner ear speaker compartment 2 and a connecting bridge 3. The connecting bridge 3 is arched and made of any one of soft rubber materials such as silicone, TPE, TPU, etc., and a memory steel wire 4 is arranged inside; the outer ear component compartment 1 and the inner ear speaker compartment 2 are both made of any one of engineering plastics such as ABS, PC, ABS+PC, ABS+PMMA, POM, PA, etc.

[0022] A PCB board 5, a battery 6 and a magnet 16 are installed in the outer ear component compartment 1, a speaker 7 is installed in the inner ear speaker compartment 2, and the speaker 7 is connected to the PCB board 5 after passing through the connecting bridge 3 through a wire 15. The connecting bridge 3 and the outer ear component compartment 1 are fixedly connected through a connector 8. The inner ear speaker compartment 2 is slidably and telescopically connected to the other end of the connecting bridge 3. One end of the connecting bridge 3 connected to the inner ear speaker compartment 2 is connected to a rod-shaped guide rail 9.
