The second through hole 1021 has a connecting groove 1026 on the side facing the outer shell 101. The connecting ring 10141 is clamped between the air vent 200 and the connecting groove 1026.
[0048] The funnel-shaped design of the extension 1014 provides a larger contact area with the outside air, increasing the flow of air between the earmuff module 1000 and the amount of outside air passing through the vent tube 200, thereby improving the ventilation of the earmuff module 1000. Furthermore, the connecting ring 10141 provided on the extension 1014 is positioned between the vent tube 200 and the connecting groove 1026 of the second through hole 1021, further strengthening the sealing performance between the outer shell 101 and the inner shell 102, and enhancing the protection between the outer shell 101 and the inner shell 102 from the influence of dust, water, and other external environments on the internal circuit board 500 and the annular speaker 300.
[0049] Specifically, the connecting ring 10141 is clamped in the connecting groove 1026 of the outer shell 101, which helps to enhance the structural strength of the connection between the outer shell 101 and the inner shell 102, and improve the durability and stability of the earmuff module 1000.
[0050] refer to Figure 4 and Figure 5The earmuff module 1000 also includes a battery 700. A third accommodating groove 1015 is provided on the shell 101. The battery 700 is arranged in the third accommodating groove 1015. The battery 700 is arranged on one side of the circumference of the annular speaker 300 and is arranged opposite to or adjacent to the secondary speaker 600.
[0051] The third accommodating groove 1015 securely holds the battery 700, protecting it from external impact or damage, extending its service life, reducing the risk of short circuits or other safety issues during use, and improving the safety of the earmuff module 1000.
