Abstract
A sound playing device and a connection establishing method thereof are disclosed. The sound playing device comprises a wireless transmission module, a detection module, and a control module. The wireless transmission module is used for establishing a connection with an electronic device via a first or a second wireless transmission path, wherein the first and the second wireless transmission path are used for receiving an audio signal and a data signal respectively. The detection module detects whether the wireless transmission module is connected to the electronic device via the first or the second wireless transmission path. When the detection module detects that the electronic device is to be connected via the second wireless transmission path, it further detects whether the electronic device is connected via the first wireless transmission path. If yes, then the control module enables the connection via the second wireless transmission path.
