A Bluetooth device is adapted to be carried on a human body, and includes: a Bluetooth module wirelessly receiving an external audio signal; a loudspeaker module for reproducing the audio signal received by the Bluetooth module; a sensing unit including a sensing circuit for sensing a conductive unit so as to generate a physical characteristic value associated with the conductive unit; and a processing unit receiving the physical characteristic value from the sensing circuit, and outputting a control signal to the Bluetooth module based on the physical characteristic value received thereby. The Bluetooth module is operable, based on the control signal from the processing unit, between one of a power-saving state, where the Bluetooth device is distal from the human body, and a working state, where the Bluetooth device is close to the human. body. |
