[0040] Optionally, as shown in Figures 2 to 5, the housing 10 includes a bottom wall portion 110 and a side wall portion 120 connected to the bottom wall portion 110. The bottom wall portion 110 and the side wall portion 120 cooperate to form a accommodating space 101. The side wall portion 120 is provided with a support surface 102 on the side facing the accommodating space 101. The support surface 102 is provided with a sound guide hole 103 connecting the accommodating space 101 and the outside of the housing 10. The sealing ring 20 is provided on the support surface 102 and surrounds the sound guide hole 103. The microphone assembly 30 includes a sound guide member 310 and a microphone 320. The sound guide member 310 is used to press the sealing ring 20 on the support surface 102 and is provided with a sound guide channel 301 that guides the sound input from the sound guide hole 103 to the microphone 320. The positioning member 40 is inserted between the housing 10 and the sound guide member 310 so that the sound guide member 310 maintains a pressing state on the sealing ring 20. The number of the sound guide holes 103 can be one or two, for example, two sound guide holes 103 are arranged side by side on the support surface 102. Of course, the number of the sound guide holes 103 can also be three, four, five, etc.

[0043] By setting the first positioning portion 311 and the second positioning portion 130, it is convenient to position and install the positioning member 40, and the positioning member 40 can continue to apply pressure to the first positioning portion 311 under the restriction of the second positioning portion 130, thereby enabling the sound guide 310 to maintain a pressing state on the sealing ring 20, which is beneficial to improving the sealing effect of the sealing ring 20 and thereby improving the usability of the earphone 100.

[0044] Optionally, as shown in FIG. 2 and FIG. 3 , the positioning member 40 is configured to be inserted between the first positioning portion 311 and the second positioning portion 130 from a side of the sound guide 310 facing away from the bottom wall portion 110 .

[0045] By arranging the positioning member 40 to be inserted between the first positioning portion 311 and the second positioning portion 130 from the side of the sound guide 310 away from the bottom wall portion 110, the sealing ring 20 will not be subjected to excessive pressure when the positioning member 40 is not installed, so that when the sealing ring 20 is installed, the sealing ring 20 will not be deformed due to the additional pressure, such as wrinkles or gaps between the supporting surface 102, thereby effectively improving the sealing effect of the sealing ring 20, reducing the difficulty of assembling the sealing ring 20, improving the assembly efficiency of the sealing ring 20, and effectively improving the yield of the earphone 100.

[0046] Optionally, as shown in Figure 3, there are two second positioning portions 130, and the two second positioning portions 130 are arranged on both sides of the sound guide 310 along the perpendicular direction F2 of the pressing direction F1. The middle area of ​​the positioning member 40 abuts against the first positioning portion 311, and the two ends of the positioning member 40 abut against the two second positioning portions 130 respectively.

[0047] By providing two second positioning portions 130 , the positioning and installation of the positioning member 40 is facilitated, and the two second positioning portions 130 are respectively in contact with the two ends of the positioning member 40 , which is conducive to achieving force balance on both sides of the positioning member 40 and improving the service life and usability of the earphone 100 .

[0049] By bending the ends of the positioning member 40 relative to the middle region of the positioning member 40, the two second positioning portions 130 abut against the ends of the positioning member 40, while the middle region of the positioning member 40 abuts against the first positioning portion 311. This makes the internal structure of the earphone 100 more compact, improves the structural integration and tightness, and helps improve the space utilization within the earphone 100. Furthermore, bending the ends of the positioning member 40 relative to the middle region of the positioning member 40 can increase the strength of the positioning member 40, reduce the possibility of damage to the positioning member 40, and thus increase the service life of the earphone.

[0050] Optionally, as shown in Figures 3 and 4, the sound guide 310 further includes a stopping block 313, which is located on the side of the main body 312 away from the bottom wall portion 110, and is spaced apart from the first positioning portion 311 along the pressing direction F1 to cooperate with each other to form a first slot 302, and the middle area of ​​the positioning member 40 is at least partially arranged in the first slot 302.

[0051] By providing the locking block 313 to cooperate with the first positioning portion 311 to form the first locking groove 302, the positioning member 40 is easily installed and fixed, which is beneficial to reducing the assembly difficulty of the earphone 100 and improving the assembly efficiency and yield of the earphone 100.

[0053] By setting the width L1 of the retaining block 313 in the vertical direction F2 to be smaller than the width L2 of the main body 312 and providing the second retaining slot 402 in the central region of the positioning member 40, the positioning member 40 is facilitated for installation, thereby reducing the difficulty of assembling the earphone 100 and improving assembly efficiency and yield. Furthermore, the simultaneous provision of the first retaining slot 302 and the second retaining slot 402 allows for dual positioning of the positioning member 40, effectively improving positioning effectiveness and enhancing assembly accuracy.

[0054] Optionally, as shown in Figures 3 and 5, the microphone 320 is disposed on the side of the main body 312 facing the bottom wall 110, the first positioning portion 311 presses the sealing ring 20 on the side facing the support surface 102, and the sound guide channel 301 extends to the main body 312 via the first positioning portion 311 and the retaining block 313. This arrangement enables sound to be transmitted from the sound guide channel 301 to the microphone 320, effectively ensuring sound transmission, and makes the internal structure of the earphone 100 more compact, improving the structural integration and tightness, and facilitating improved space utilization within the earphone 100.

[0055] Optionally, as shown in FIG. 3 , the microphone assembly 30 further includes a lead wire 330 connected to the microphone 320 , and a lead wire groove 303 is further provided on one side of the main body 312 facing the bottom wall 110 , in which the lead wire 330 is disposed.

[0057] Optionally, as shown in FIG. 3 , the housing 10 further includes a guide portion 140 disposed on the bottom wall portion 110 , and the guide portion 140 is used to guide the sound guide 310 along the pressing direction F1 .

[0058] By providing the guide portion 140 on the bottom wall portion 110 , it is convenient to position and install the sound guide 310 , reducing the difficulty of assembling the sound guide 310 , and effectively ensuring that the sound guide 310 presses the sealing ring 20 along the pressing direction F1 , thereby improving the sealing effect of the sealing ring 20 .

[0059] Optionally, as shown in FIG6 , the guide portion 140 is configured so that the sound guide 310 has a tendency to move toward the support surface 102 and the bottom wall portion 110 simultaneously, or to move away from the support surface 102 and the bottom wall portion 110 simultaneously. This configuration facilitates the positioning and installation of the sound guide 310, helps reduce the difficulty of assembling the sound guide 310, and can further enhance the pressure and holding effect of the sound guide 310 on the sealing ring 20, thereby improving the sealing effect of the sealing ring 20.
