A communication device includes a first body, a second body, a first audio module, and a second audio module. The second body is rotatably connected to the first body. The first audio module is disposed on the first body. The second audio module is at least partially disposed on the first body. When the second body rotates relatively to the first body to be in a first state to switch the communication device to be in a first operation mode, at least a portion of the first audio module is turned on, and the second audio module is turned off. When the second body rotates relatively to the first body to be in a second state to switch the communication device to be in a second operation mode, the first audio module is turned off, and the second audio module is turned on.
