A plurality of feet 122 are coupled to the lower end of the box body 121 to prevent the box body 121 from slipping.

The main PCB 140 is mounted within the box body 121 of the device box 120. And, the Bluetooth module 151 is connected to one side of the main PCB 140. The Bluetooth module 151 is a device that is connected to the main PCB 140 within the device box 120 and wirelessly connects to personal terminals such as smartphones, laptops, and MP3 players.

The Bluetooth module 151 is paired with the speaker module 153 to become a wireless speaker. The speaker module 153 is connected to the Bluetooth module 151 and is provided in the upper area of the device box 120, and is a means of outputting sound. In this embodiment, the speaker module 153 is coupled to the upper inner wall of the main body cover 123 and connected to the Bluetooth module 151 through the main PCB 140.
