In this embodiment, the side of the boss structure 24 facing the opening structure 25 is sealed and connected with the abutment on the door, so the side of the boss structure 24 facing the opening structure 25 is called the door dry area, and since the side of the boss structure 24 facing away from the opening structure 25 is not connected to any parts, rainwater will fall on this area, so the side of the boss structure 24 facing away from the opening structure 25 is called the door wet area.
[0052] Specifically, in the present embodiment, the connector 26 is disposed in the door stem area, so that the safety of the power supply of the connector 26 can be ensured.
[0053] In some embodiments of the present invention, Figure 5As shown, the end of the first surface 211 away from the second surface 212 is provided with a first boss portion 213 disposed away from the accommodating cavity. In this embodiment, the first boss portion 213 can prevent rainwater falling on the basin frame 21 from sliding onto the first end cover 22, and plays a certain stopping role, thereby preventing rainwater from entering the speaker body through the first sound hole 221 of the first end cover 22, thereby improving the reliability of the speaker body. The end of the second surface 212 away from the first surface 211 is provided with a second boss portion 214 disposed away from the accommodating cavity. In this embodiment, the second boss portion 214 can prevent rainwater falling on the basin frame 21 from sliding onto the second end cover 23, and plays a certain stopping role, thereby preventing rainwater from entering the speaker body through the second sound hole 231 of the second end cover 23, thereby improving the reliability of the speaker body.
[0054] Furthermore, in the present embodiment, the connection between the first surface 211 and the second surface 212 is designed to be recessed toward the interior of the accommodating cavity, which is relatively simple and does not require additional drainage parts, thereby helping to save costs.
