In some embodiments of the present invention, referring to fig. 1, a first inserting groove 111 is disposed on a wall of the accommodating cavity 11 facing the mounting opening 12, a second inserting groove 21 is disposed on a surface of the cover plate 20 adjacent to the accommodating cavity 11, one end of the circuit board 30 is inserted into the first inserting groove 111, and the other opposite end of the circuit board 30 is inserted into the second inserting groove 21. So set up, apron 20 and the chamber wall cooperation that holds chamber 11 realize the centre gripping to circuit board 30 jointly, when circuit board 30 was dismantled to needs, only need take off apron 20 from casing 10, just can remove spacing to circuit board 30, take out circuit board 30.

It should be noted that, in order to facilitate the electrical connection between the circuit board 30 and other components of the earphone 100, a through hole for passing a power supply line may be further formed on the cavity wall of the accommodating cavity 11 facing the mounting opening 12.

Of course, there are many ways for the cover plate 20 to cooperate with the cavity wall of the accommodating cavity 11 to limit the circuit board 30, for example, a square first clamping block is disposed on the cavity wall of the accommodating cavity 11 facing the mounting opening 12, a square second clamping block is disposed on the surface of the cover plate 20 adjacent to the accommodating cavity 11, a first clamping groove cooperating with the first clamping block is disposed on one side of the circuit board 30, and a second clamping groove cooperating with the second clamping block is disposed on the other opposite side of the circuit board 30; for another example, the cavity wall of the accommodating cavity 11 facing the mounting opening 12 is convexly provided with a cylindrical threaded post, the circuit board 30 is concavely provided with a threaded hole matched with the threaded post, the surface of the cover plate 20 adjacent to the accommodating cavity 11 is convexly provided with two abutting blocks, and the two abutting blocks are respectively abutted against the two plate surfaces of the circuit board 30 to limit the rotation of the circuit board 30, which is not mentioned in a row.

Specifically, referring to fig. 1 and 2, the cover plate 20 is provided with an annular insertion portion 22, and the annular insertion portion 22 is inserted into and matched with the mounting opening 12. So configured, the cover plate 20 is in plugging fit with the mounting opening 12 through the annular plugging portion 22, so as to realize detachable connection of the cover plate 20 and the housing 10. It should be noted that the annular meaning of the annular insertion part 22 may be a hollow circular ring or a circular ring without a hollow, which is not described herein again.

In other embodiments of the present invention, referring to fig. 2 and 3, the cavity wall of the accommodating cavity 11 adjacent to the mounting opening 12 is provided with a clamping protrusion 112; the circuit board 30 is rotatably installed in the accommodating cavity 11, the circuit board 30 is provided with a clamping groove 31, and the clamping groove 31 is matched with the clamping protrusion 112 in a clamping mode after the circuit board 30 rotates by a preset angle. With the arrangement, when the circuit board 30 is installed, the circuit board 30 is placed into the accommodating cavity 11 and then rotated by a certain angle to realize the matching of the clamping groove 31 and the clamping protrusion 112; when the circuit board 30 is disassembled, the circuit board 30 is rotated, so that the clamping groove 31 on the circuit board 30 is separated from the clamping protrusion 112, and the circuit board 30 can be taken out of the accommodating cavity 11.

The preset angle is adjusted according to the relative position of the circuit board 30 and the clamping protrusion 112, the length of the clamping protrusion 112, and the like, and may be any angle between 0 ° and 360 °, specifically, the preset angle may be 5 °, 10 °, 80 °, 180 ° … … 355 °, and the like, and is not limited specifically herein.

Of course, the number of the catching protrusions 112 may be 1, 5, 10, etc., which may be adjusted as needed, and is not particularly limited herein.

It should be noted that the position of the clamping protrusion 112 should be adapted to the position of the clamping groove 31 on the circuit board 30, so as to avoid the situation that after the clamping groove 31 on the circuit board 30 is matched with the clamping protrusion 112, a part of the circuit board 30 still extends out of the mounting opening 12, so that the cover plate 20 cannot close the mounting opening 12.

Further, referring to fig. 2, in order to facilitate rotation of the circuit board 30, the latching protrusion 112 has a first end 1121 and a second end 1122 that are opposite to each other in the circumferential direction of the accommodating cavity 11, and the thickness of the latching protrusion 112 in the axial direction of the accommodating cavity 11 is gradually increased from the first end 1121 to the second end 1122.
