Problems solved by technology
[0003] Due to the relatively small number of wireless broadcasting base stations, the range of wireless broadcasting signals emitted by them can only cover cities and some towns, and cannot cover the wild and high roads, and the wireless broadcasting signals cannot reach the closed space below the ground level. Therefore, the scope of the audio signal corresponding to the broadcast program can be played by the mobile terminal is limited, which affects the normal operation of the broadcast service of the mobile terminal

Embodiments of the present invention provide a method and a device for playing an audio signal. The method comprises: playing a first audio signal converted according to a radio broadcast signal; when a received signal strength indicator (RSSI) is smaller than a preset first threshold value, obtaining address information corresponding to frequency band information of the radio broadcast signal; and playing a second audio signal converted according to a media stream, wherein the media stream is obtained according to the address information. In the present invention, when a mobile terminal plays the first audio signal converted according to the obtained radio broadcast signal, if the RSSI is smaller than the preset first threshold value, the address information corresponding to the frequency band information of the radio broadcast signal is obtained, so that the mobile terminal can play the second audio signal converted according to the obtained media stream corresponding to the address information, thereby enlarging the range in which the mobile terminal can play an audio signal corresponding to a broadcasted program, and ensuring normal operation of broadcasting services of the mobile terminal.
Description
technical field [0001] Embodiments of the present invention relate to communication technologies, and in particular to a method and device for playing audio signals. Background technique [0002] With the continuous development of mobile terminals, it becomes possible to integrate broadcast functions. The mobile terminal obtains the wireless broadcast signal through the integrated FM chip, and plays the audio signal converted according to the above wireless broadcast signal. [0003] Due to the relatively small number of wireless broadcasting base stations, the range of wireless broadcasting signals emitted by them can only cover cities and some towns, and cannot cover the wild and high roads, and the wireless broadcasting signals cannot reach the closed space below the ground level. Therefore, the range in which the mobile terminal can play the audio signal corresponding to the broadcast program is limited, and the normal progress of the broadcast service of the mobile ter...
