[0040] Specifically, the circuit board 3 may be directly placed in the accommodating cavity 11 or may be connected to the cavity wall of the accommodating cavity 11 by snapping or supported in the accommodating cavity 11 by a supporting structure.

[0041] Exemplarily, for ease of description, the first opening 12 is set to be located on the top surface of the middle frame 1, part of the button assembly 2 is located above the middle frame 1, and part of the button assembly 2 can extend into the accommodating cavity 11 through the first opening 12, so that when the user presses down on the button assembly 2, the switch button 4 is triggered, thereby realizing the switching action of the sports earphones.

[0042] Further, refer to Figure 2 As shown, in order to realize the connection between the antenna 5 and the circuit board 3 located in the middle frame 1 to realize the antenna signal transmission function, the antenna 5 can be connected to the key assembly 2 first, and then the part of the key assembly 2 extending into the accommodating cavity 11 can be connected to the circuit board 3, so that the antenna signal can be transmitted to the key assembly 2 through the antenna 5, and then transmitted to the circuit board 3 through the key assembly 2, thereby realizing the connection between the antenna 5 and the circuit board 3, thereby realizing the antenna signal transmission. At the same time, the key assembly 2 that triggers the switch action of the sports earphone is used to transmit the antenna signal to the circuit board 3 to realize the connection of the antenna signal, and there is no need to design an additional transmission structure to realize the connection between the antenna 5 and the circuit board 3, so the structure of the entire sports earphone can be simplified.

[0043] The sports earphones of this embodiment include a middle frame 1, a key assembly 2, a circuit board 3, a switch button 4 and an antenna 5. The middle frame 1 has a receiving cavity 11, and one side of the middle frame 1 has a first opening 12 connected to the receiving cavity 11.
