[0065] Example 2

The WS device module includes a workstation; the headphone module includes headphones; and the external device module includes a USB PC device and device A.

[0067] As an example of this embodiment, see Figure 8, which is a structural diagram of a Bluetooth dual-play mode setting device for hands-free playback (external device and WS module connection mode) provided by one embodiment of the present invention. As shown in Figure 8, when the Workstation is connected to the USB PC device to establish a PCM (Pulse Code Modulation) communication channel, and the Workstation is not connected to the headset, the first peripheral device transmits data via the PCM communication channel to the WS_AUDIO of the Workstation, and is played hands-free through the SPK (Speaker) of the Workstation; the first sound pickup data obtained after processing by the MIC (Microphone) of the Workstation is sent to the USB PC device via the PCM communication channel.

[0068] As another example of this embodiment, see Figure 9, which is a structural diagram of a Bluetooth dual-play mode setting device for headphone playback (external device and WS module connection mode) provided by one embodiment of the present invention. As shown in Figure 9, when the workstation is connected to the USB PC device to establish a PCM communication channel, and the workstation is connected to the headphone to establish a SCO (Synchronous Connection Oriented Link) communication channel and an A2DP (Advanced Audio Distribution Profile) communication channel, the second peripheral transmission data is transmitted to the WS_AUDIO of the workstation via the PCM communication channel, transmitted to the WS_BT via the internal mSBC (modified SubBand Coding) or SBC (SubBand Coding) channel of the workstation, and then sent to the SPK of the headphone via the SCO communication channel or the A2DP communication channel for headphone playback; the second sound pickup data obtained after processing by the headphone MIC is sent to the AUDIO of the headphone, sent to the WS_BT of the workstation via the SCO communication channel, transmitted to the WS_AUDIO via the internal mSBC, and then forwarded to the USB PC device via the PCM communication channel.

The second headphone transmits data from device A via the SCO communication channel or the A2DP communication channel to the SPK of the headphone for headphone playback. The third sound pickup data obtained after processing by the headphone MIC is sent to the AUDIO of the headphone and then sent to device A via the SCO communication channel.

[0070] As another example of this embodiment, refer to FIG11 , which is a structural diagram of a Bluetooth dual-play mode setting device for hands-free playback (wired forwarding working mode) provided by an embodiment of the present invention. As shown in Figure 11, when the Workstation is not connected to the USB PC device, when the Workstation is connected to the headset to establish a wired transmission communication channel, the headset is connected to the device A to establish the SCO communication channel and the A2DP communication channel, and it is determined to enter the wired forwarding working mode. The third peripheral transmission data is transmitted by the device A to the headset through the SCO communication channel or the A2DP communication channel. The headset forwards the third peripheral transmission data to the WS_BT (Bluetooth chip module of the workstation) of the workstation through the wired transmission communication channel, and then transmits it to the WS_AUDIO of the workstation through the internal SBC or mSBC channel, and then is played hands-free by the SPK of the workstation; the fourth sound pickup data obtained after processing by the MIC of the workstation is transmitted to WS_BT through the internal mSBC channel of the WS_AUDIO of the workstation, and then forwarded to the headset, and finally sent to device A through the SCO communication channel.

[0071] As another example of this embodiment, see Figure 12, which is a structural diagram of a Bluetooth dual-play mode setting device for hands-free playback (wireless forwarding mode) provided by one embodiment of the present invention. As shown in Figure 12, when the workstation and the USB PC device are not connected, when the workstation is connected to the headset to establish a wireless transmission communication channel, and the headset is connected to device A to establish the SCO communication channel and the A2DP communication channel, it is determined that the wireless forwarding mode has been entered. The fourth peripheral device transmission data is transmitted by device A to the headset via the SCO communication channel or the A2DP communication channel. The headset forwards the fourth peripheral device transmission data to the workstation's WS_BT via the wireless transmission communication channel, and then transmits it to the workstation's WS_AUDIO via an internal SBC or mSBC channel. The workstation's SPK then performs hands-free playback. The fifth sound pickup data obtained after processing by the workstation's MIC is transmitted to the WS_BT via the workstation's WS_AUDIO via the internal mSBC channel, and then forwarded to the headset via the wireless transmission communication channel. Finally, it is sent to device A via the SCO communication channel.
