The PCBA control switch board 3 and the button cover 5 of the utility model are installed on the plastic inner box 1, and do not need to be installed on the wooden outer box 2. The material properties of the plastic inner box 1 are dense and stable, and it is easy to set screw holes for installing the PCBA control switch board 3 and the button cover 5, and the PCBA control switch board 3 and the button cover 5 are installed firmly; on the other hand, the structural position of the button 4 of the plastic inner box 1 is easy to be waterproof. Even if external water vapor can enter the first opening 21 of the wooden outer box 2, it is difficult to enter the interior of the speaker through the plastic inner box 1.

[0019] like Figure 2-Figure 5 As shown, the lower end of the key cover 5 is provided with a cover cavity 52, and the cover cavity 52 is simultaneously covered outside the PCBA control switch board 3 and the key 4. The cover cavity 52 can simultaneously protect the PCBA control switch board 3 and the key 4, and prevent the user from observing or contacting the PCBA control switch board 3 from the first opening 21.
