Abstract

A radio device capable of switching play message automatically and a method thereof. The device includes a wireless signal receiving module, a storing module, a speaker module and a processing module. The wireless signal receiving module receives a wireless signal of a broadcasting channel and demodulates an original signal based on the wireless signal. The storing module stores a music file. The speaker module selectively plays a broadcasting message, based on the original signal, or the music file. The processing module calculates a signal strength value based on the original signal, and determines whether the signal strength value is greater than a strength threshold value, if so, the processing module transmits the original signal to the speaker module, such that the speaker module plays the broadcasting message based on the original signal, otherwise, the processing module controls the speaker module to play the music file.
