Patent ID: 8073513

Claim:
A wireless communication device, comprising: an earphone acting as an internal antenna to receive radio frequency signals; and a frequency modulation integrated circuit (FM IC) operable to receive and demodulate the radio frequency signals and output the demodulated signals; a microphone operable to receive input communication voice signals; an analog switch connected to the FM IC and the microphone, operable to output the demodulated signals or the communication voice signals; and a main processor connected to the analog switch, and comprising a software amplifier operable to amplify the demodulated signals or the communication voice signals and output the amplified demodulated signals or communication voice signals to the earphone; wherein a working mode of the wireless communication device comprises a communication mode and a radio mode, and the analog switch receives the demodulated signals from the FM IC and outputs the demodulated signals to the main processor when the wireless communication device is in the radio mode.
