Switching method of built-in antenna and exposed antenna of FM receiver as well as terminal thereof

The invention provides a switching method of a built-in antenna and an exposed antenna of an FM receiver as well as a corresponding terminal thereof. The terminal comprises an FM receiver, the built-in antenna, the exposed antenna, a CPU, a detection module and an antenna switching module. The CPU detects that the exposed antenna is switched in when the terminal switches in the exposed antenna inthe on-state of the FM receiver; the detection module is used for detecting the RSSI of signals received by the built-in antenna and the exposed antenna; the selection module is used for comparing the RSSI values of the signals received by the built-in antenna and the exposed antenna, which are detected by the detection module. The antenna with the larger RSSI value is selected, and then the CPU controls the antenna switching module to switch in the selected antenna as the current receiving antenna. The switching method performs a switching between the built-in antenna and the exposed antennaaccording to the quality of the signals received by the built-in antenna and the exposed antenna from a station, can realize a seamless switching between the built-in antenna and the exposed antenna,and raises the receiving quality and the effect of the FM receiver.
