To receive the audio signal with a signal switching device, and the audio signal is converted to FM (frequency modulation; FM) broadcast signal by FM radio receiver initial frequency is transmitted to the target; the signal switching device with frequency modulation (FM) receiver to search for alternative frequency is not used, when the initial frequency disturbance signal switching device, automatically switched to FM radio receiver instead of frequency to send the FM signal to the target. The invention also discloses an automatic updating method for the wireless link, which automatically creates another new wireless link when the wireless link between the signal switching device and the target FM broadcast receiver is disturbed.
