The speaker body comprises a control chip provided in the speaker body and a digital transmission high frequency module connected to the control chip. A Bluetooth speaker-based sharing system, comprising at least two Bluetooth speakers which are as stated above, and further comprising an external input device. A Bluetooth transceiver unit of one of the Bluetooth speakers is in signal connection with the external input device, and outputs a signal to a microcontroller unit; the microcontroller unit outputs the signal to the digital transmission high frequency module of the Bluetooth speaker; then the digital transmission high frequency module of the Bluetooth speaker outputs the signal to the digital transmission high frequency module of the rest of the Bluetooth speakers. The Bluetooth speaker enables several people to share audio information (such as music), and ensures the sound quality of the shared audio information (such as music).
