In addition, the replaceable outer cover 100 and the inner cover 200 are fixed by buckles and holes, so the replaceable outer cover 100 can be replaced to assemble headphones for use in different scenarios, and it is also convenient for the replaceable outer cover 100 to be removed.

[0042] The antenna 300 can be glued to the antenna connection surface 200a of the inner cover 200, and after the replaceable outer cover 100 and the inner cover 200 are connected, the antenna 300 is maintained between the inner cover 200 and the replaceable outer cover 100. The antenna 300 can be pre-assembled with the inner cover 200, and only the replaceable outer cover 100 is replaced.

[0043] like Figures 1 to 3As shown, the earphone with replaceable outer cover further comprises a shell 400, and the shell 400 is connected to the circuit board connection surface 200b, so that the circuit board is encapsulated between the shell 400 and the inner cover 200. The side of the shell 400 away from the inner cover 200 is the side inserted into the ear canal. The shell 400 and the inner cover 200 bracket can also be connected in a snap-fit ​​manner.

[0044] refer to Figure 3 and Figure 4 , the circuit board connection surface 200b is provided with a plurality of posts 230 for penetrating the circuit board. The posts 230 are connected to the housing 400 so that the circuit board is fixed between the circuit board connection surface 200b and the housing 400.

[0049] The first hook 211 is made of an elastic material, and utilizes the elastic deformation of the first hook 211 to squeeze through the first hole 110 and reach the upper side of the replaceable outer cover 100. At this time, the first hole 110 can restore its shape and abut against the first step 111, so that the first buckle 210 can be buckled on the first hole 110. After the replaceable outer cover 100 is bent upward, the first hook 211 elastically deforms and passes back to the replaceable outer cover 100, so that the first buckle 210 and the first hole 110 are released and disengaged.

[0050] Similarly, the second hole 120 passes through the replaceable outer cover 100, and a second step is provided on the inner wall of the second hole 120; a second hook 221 is provided on the rear side of the second buckle 220, the second buckle 220 passes through the second hole 120, and the second hook 221 abuts against the second step. The connection and disconnection method of the second hole 120 and the second buckle 220 can refer to the first hole 110 and the first buckle 210, and will not be described here.

[0051] The first hook body 221 and the first buckle 210 can be integrally formed, and of course the second hook body 221 and the second buckle 220 can be integrally formed.

[0052] like Figure 1 As shown, the first hook body 211 is located at the front side of the first buckle 210, and the second hook body 221 is located at the rear side of the second buckle 220, so that after the replaceable outer cover 100 and the inner cover 200 are buckled together, the stability of the connection between the two can be improved.

[0053] like Figure 5 As shown, the antenna 300 includes an inner ring portion 310, an outer ring portion 320, and a radial branch portion 330 connected between the inner ring portion 310 and the outer ring portion 320;
