The second audio processing circuit 137 is coupled with the second control circuit 135, the second audio playback circuit 172, and the second voice receiving circuit 174. The second audio processing circuit 137 is arranged to operably process the audio data transmitted from the Bluetooth host device 110 (e.g., to encode or decode the audio data, and/or to conduct format conversion on the audio data) according to the instructions of the second control circuit 135, and arranged to operably control the second audio playback circuit 172 to playback contents of the audio data. The second audio processing circuit 137 is further arranged to operably encode the sounds received by the second voice receiving circuit 174 to generate related sound data.
In some embodiments, the first control circuit 125 is further arranged to operably control the first member device 120 to act as a Bluetooth Central in a Bluetooth piconet, and to operably adjust the clock signals employed by the first member device 120, so as to synchronize a piconet clock utilized among the first member device 120 and other Bluetooth devices. In this situation, the second control circuit 135 is further arranged to operably control the second member device 130 to act as a Bluetooth Peripheral in the Bluetooth piconet, and to operably adjust the clock signals employed by the second member device 130, so as to synchronize the piconet clock utilized between the second member device 130 and the first member device 120.
