For example, two sound guide pipes 116 can be arranged on opposite sides of the bass speaker 1122 to facilitate sound wave transmission. One end of the sound guide pipe 116 is connected to the second side plate 117 of the shell 110. Since the first side plate 115 and the second side plate 117 are parallel, the sound guide pipe 116 needs to pass through the functional cavity 111. It can be understood that the sound guide pipe 116 can also be arranged on a side perpendicular to the first side plate 115, and the sound guide pipe 116 can also achieve the purpose of sound wave transmission.

[0034] As shown in Figure 4 , the turntable assembly 170 includes a drive motor 172 arranged on the support plate 152 and a turntable 174 rotationally connected to the support plate 152.
