Detailed description of the invention
Understandable for enabling the above-mentioned purpose of the present invention, feature and advantage to become apparent from, below in conjunction with the accompanying drawings and specific embodiment party
The present invention is further detailed explanation for formula.
Embodiment one
As it is shown in figure 1, the present invention provides a kind of audio switching method, including:
Step S1, monitors the intensity of the broadcast singal received in real time whether more than presetting minimum threshold；
If so, step S2, then play broadcast audio according to the broadcast singal received；
If it is not, step S3, then local audio is play in switching.Here, the broadcast singal of real-time reception current selected frequency range, and to this letter
Number carry out strong and weak detection, if more than presetting minimum threshold, then playing out, corresponding broadcast audio if less than equal to described
Preset minimum threshold, then it is assumed that current broadcast signal is the best, and the local audio switched in Play System plays out, as play
What this locality prestored audio frequency, and continue to current broadcast signal as the FM signal of selected frequency range detects, until greatly
In default minimum threshold, just broadcast audio is play in switching, thus avoids occurring in broadcast noise, promotes user and listens to experience.
Preferably, described broadcast singal is FM signal.
Preferably, step S2, play broadcast audio according to the broadcast singal received, including:
The broadcast singal received is filtered, demodulates, amplifies and obtain broadcast audio.
Preferably, step S3, switching broadcasting local audio, including:
The voice message switched over；
Local audio is play in switching.Concrete, before the audio frequency prestored in switching to Play System, it is also possible to include current
When signal is the best, then play by voice message user local audio to be switched to, promote Consumer's Experience.
Preferably, step S3, switching broadcasting local audio, including:
Ask the user whether to be switched to local audio；
If receiving user to select the voice answer-back being, then local audio is play in switching.Concrete, prestore in switching to Play System
Before good audio frequency, it is also possible to include when current demand signal is the best, then whether it is switched to local audio by voice message user and plays,
The choosing of user speech response such as voice answer-back is then to be switched to local audio, promote Consumer's Experience further.
Preferably, step S3, switching broadcasting local audio, including:
Voice asks the user whether to be switched to local audio；
If receiving the title of user speech response local audio, then the local audio of corresponding title is play in switching.Concrete, switching to
Before the audio frequency prestored in Play System, it is also possible to include when current demand signal is the best, then whether pass through voice message user
It is switched to local audio play, user speech response, says the title of local audio, then play and specify audio frequency, make local audio
Broadcasting more personalized.
Step S2, then play broadcast audio according to the broadcast singal received, including:
When play before be local audio time, the voice message switched over；
Broadcast audio is play according to the broadcast singal received.Here, when playing appointment audio frequency, detect that broadcast singal is more than
Presetting minimum threshold, now system can switch back into broadcast audio by audio prompt user, promotes Consumer's Experience.
Step S2, then play broadcast audio according to the broadcast singal received, including:
When play before be local audio time, voice asks the user whether to be switched to broadcast audio；
If receiving user to select the voice answer-back being, then play broadcast audio according to the broadcast singal received.Refer to here, ought play
During accordatura frequency, detecting that broadcast singal is more than default minimum threshold, now whether system can be switched back into by audio prompt user
Broadcast audio, carries out corresponding operating according to the voice answer-back of user, promotes Consumer's Experience further.
Preferably, described response is voice answer-back, to improve safety.
Embodiment two
As in figure 2 it is shown, the present invention also provides for another kind of Audio conversion system, including monitoring modular 1, for monitoring in real time receive wide
Whether broadcast the intensity of signal more than presetting minimum threshold；
Broadcast module 2, for the most then playing broadcast audio according to the broadcast singal received；
Local module 3, for if it is not, then switch and play local audio.
Preferably, described local module 3, for the voice message switched over；Local audio is play in switching.
Preferably, described local module 3, it is used for asking the user whether to be switched to local audio；If receiving user to select the language being
Sound response, then local audio is play in switching.
Preferably, described local module 3, ask the user whether to be switched to local audio for voice；If receiving user speech
The title of response local audio, then the local audio of corresponding title is play in switching.
Preferably, described broadcast module 2, for when play before be local audio time, the voice message switched over；
