[0024] The main frame 1 includes a main frame 101, a stabilizing block 102, a sound module 103, an extrusion plate 104 and a magnet 105. The main frame 101 serves as the main structure of the entire headset, carrying other components such as the sound module 103, the stabilizing block 102, the extrusion plate 104, etc. The front side wall of the main frame 101 is fixedly connected with a stabilizing block 102. There are four stabilizing blocks 102, which are symmetrically arranged on the side walls of the sound module 103. The stabilizing blocks 102 are used to fix and support the sound module 103 to ensure that it will not shift or be damaged during exercise or daily use. The stabilizing blocks 102 are used to fix and support the sound module 103 to ensure that it will not shift or be damaged during exercise or daily use. 2 is fixedly connected to the inner wall of the main frame 101 with a sound module 103, which is responsible for converting electrical signals into sound signals and transmitting them to the user's auditory nerves through the bones. The rear wall of the sound module 103 is fixedly connected to an extrusion plate 104. There are four extrusion plates 104, which are arranged in an array on the rear wall of the sound module 103. The extrusion plate 104 cooperates with the limit ring 302 and the extrusion spring 303 to reset the device after the protective cover 2 is pushed out. A magnet 105 is arranged inside the main frame 101, and the magnet 105 is located directly behind the sound module 103.

[0025] The protective cover 2 includes a cover shell 201, a corresponding groove 202, a fixing block 203 and a protective film 204. The cover shell (201) serves as an external protective structure to protect the internal components from damage by the external environment. A corresponding groove 202 is provided at the middle position of the rear side wall of the cover shell 201. There are four corresponding grooves 202, which are symmetrically arranged on the side wall of the cover shell 201. The corresponding grooves 202 are provided correspondingly to the stabilizing block 102 and are engaged with each other to ensure the correct installation and fixation of the protective cover 2 and the main frame 1. The rear end of the cover shell 201 is fixedly connected with the fixing block 203. The bottom end of the fixing block 203 generates a magnetic attraction reaction with the magnet 105 to fix the position of the protective cover 2. A protective film 204 is provided inside the front side wall of the cover shell 201. The protective film 204 further protects the sound module 103 or other sensitive components to prevent the intrusion of dust, moisture, etc. The cover shell 201 is sleeved with the sound module 103.

[0026] The pop-up mechanism 3 includes a movable plate 301, a limiting ring 302, an extrusion spring 303, a connecting plate 304 and a pressing plate 305. The movable plate 301 is the main moving part of the pop-up mechanism 3 and is responsible for moving or popping out when needed. The limiting ring 302 is fixedly connected to the front side wall of the movable plate 301. The limiting ring 302 limits the movement range of the extrusion plate 104 and the extrusion spring 303 to ensure that they move according to a predetermined trajectory. The extrusion spring 303 is sleeved inside the limiting ring 302, and the extrusion spring 303 is fixedly connected to the movable plate 301. The extrusion spring 303 provides power for the movable plate 301 so that it can return to its original position after the external force disappears. The limiting ring 302 and There are four extrusion springs 303, which are arranged in an array on the front side wall of the movable plate 301. The rear side wall of the movable plate 301 is fixedly connected with a connecting plate 304, which connects the movable plate 301 and the pressing plate 305 to transmit the user's operating instructions. The limiting ring 302 is correspondingly arranged with the extrusion plate 104 and is socketed with each other. The rear side wall of the connecting plate 304 is fixedly connected with a pressing plate 305. The pressing plate 305 is a component directly operated by the user and triggers the action of the pop-up mechanism 3 by pressing. The movable plate 301 is socketed with the main frame 101 and is located between the sound module 103 and the magnet 105. The pressing plate 305 is slidably connected with the main frame 101.

[0027] In actual use, when the user needs to replace the protective cover 2, the user can press the pressing plate 305 to move the movable plate 301 inward. Under the action of the extrusion spring 303, the protective cover 2 partially or completely exposes the sound module 103. At this time, the user can remove the protective cover 2 for cleaning or replacement. When the user installs the protective cover 2, the protective cover 2 can be placed at the corresponding position of the main frame 1. Through the magnetic effect of the magnet 105, the protective cover 2 is reset under the action of the magnet 105, and the sound module 103 is re-stored in the protective cover 2. During the whole process, the protective cover 2 cooperates with the stabilizing block 102 on the main frame 1 through the corresponding groove 202 to ensure the stability and safety of the earphones.
