After the operating mode of the Wi-Fi communication modules of first mobile terminal is switched to talkback mode, it can pass through The physical button (such as Home major keys) of first mobile terminal described in long-press or by being installed on the soft of first mobile terminal Speech talkback virtual key in part interface gathers voice signal to trigger the microphone.The voice letter of the microphone acquisition After number being converted to voice baseband signal through the baseband chip, and then the audio base band is believed by the Wi-Fi transceiver It number is modulated on carrier wave corresponding with the communication channel that the Wi-Fi communication modules are presently in, generates voice radiofrequency signal, and The voice radiofrequency signal is sent to second mobile terminal by the Wi-Fi antennas.

Referring to Fig. 3, in an embodiment of the invention, the method further includes：

Step S14：The Wi-Fi that second mobile terminal is received by the GPS module of first mobile terminal communicates The voice signal that module is sent.

Referring to Fig. 4, the GPS module by first mobile terminal receives the Wi- of second mobile terminal The voice signal that Fi communication modules are sent, including：

Step S141：The Wi-Fi that second mobile terminal is received by the GPS module of first mobile terminal communicates The voice radiofrequency signal that module is sent, and the voice radiofrequency signal is demodulated to obtain voice baseband signal；

Step S142：The voice baseband signal is reduced into voice by the baseband chip of first mobile terminal to believe Number；

Step S143：The voice signal is played by the receiver of first mobile terminal.

Specifically, the Wi-Fi communication modules of second mobile terminal equally may include Wi-Fi mode and talkback mode two Kind operating mode.When the Wi-Fi communication modules of second mobile terminal are in talkback mode, second mobile terminal can Voice signal is sent to first mobile terminal by the Wi-Fi communication modules.Wherein, second mobile terminal is to language Acquisition, processing and the forwarding step of sound signal can refer to the associated description in embodiment illustrated in fig. 2, not repeat herein.It is described The baseband chip of first mobile terminal is also electrically connected with the GPS module and the receiver.When first mobile terminal The Wi-Fi communication modules of GPS module and second mobile terminal when being in same communication channel, first movement is eventually End can receive the voice radiofrequency signal that the Wi-Fi communication modules of second mobile terminal are sent by the GPS module.It is described Voice radiofrequency signal is received through institute's GPS module, and demodulates to obtain voice baseband signal by the baseband chip；The audio base band Signal is further reduced into voice signal by the baseband chip, and then plays the voice signal by the receiver.

Referring to Fig. 5, in an embodiment of the invention, the GPS module by first mobile terminal receives The voice radiofrequency signal that the Wi-Fi communication modules of second mobile terminal are sent, and the voice radiofrequency signal is demodulated To voice baseband signal, including：

Step S1411：The signal received to the GPS module of first mobile terminal is filtered, and is isolated The voice radiofrequency signal of first frequency；Wherein, the first frequency is equal to the corresponding carrier frequency of the communication channel；

Step S1412：Down-converted is carried out to the voice radiofrequency signal of the first frequency, obtains the language of second frequency Sound intermediate-freuqncy signal；Wherein, the second frequency is equal to the carrier frequency of GPS signal；
