Embodiment three
The embodiment of the invention provides a kind of audio-frequency processing methods, applied to terminal described in embodiment two, the terminal
It further include processor.Referring to Fig. 4, Fig. 4 is a kind of flow chart one of audio-frequency processing method provided in an embodiment of the present invention, the reality
The method of example is applied once being triggered by user, then the process in the embodiment passes through terminal automatic running, wherein each step is being transported
Can be when row and successively carried out according to the sequence in such as flow chart, be also possible to according to the actual situation multiple steps simultaneously into
Row, herein and without limitation.As shown in figure 4, method includes the following steps:
Step S301: the first audio signal is acquired by the microphone module in microphone.
In embodiments of the present invention, the microphone module in microphone includes ASIC (Application Specific
Integrated Circuit) chip, circuit board and microphone element.Wherein, microphone element includes MEMS (Micro-
Electro-Mechanical System), diaphragm, the components such as backboard.Extraneous sound is collected in the microphone module
Afterwards, sound wave can cause the variation of air pressure, and diaphragm is bent with the variation of air pressure, and backboard is thicker and porous, as the air flows past,
Backboard is remain stationary, and when diaphragm vibration, the capacitance between diaphragm and backboard will change, and asic chip is by the capacitor of variation
Amount is converted to electric signal, obtains audio signal, i.e. the first audio signal.
Step S302: the first audio signal is handled using the processing module in microphone.
In embodiments of the present invention, processing module is additionally provided in microphone, terminal is using the processing module to the first sound
Frequency signal is pre-processed, and useful audio signal is selected out, for example, the identifiable voice messaging of terminal, call-information etc..
Step S303: by the processor of treated the first audio signal is sent to terminal.
In embodiments of the present invention, processor is configured in terminal, the processing module in microphone believes the first audio
After number being pre-processed, by treated, the first audio-frequency information is sent to the processor of terminal to terminal, then has the processor of terminal
To treated, the first audio-frequency information is further is handled.
Referring to Fig. 5, Fig. 5 is a kind of flow diagram two of audio-frequency processing method provided in an embodiment of the present invention, it is pair
The further refinement of step S302, as shown, method includes the following steps:
Step S3021: the first audio signal is compared with audio signal is prestored using the processing module in microphone.
In embodiments of the present invention, processing module includes processing region and storage region, is previously stored in storage region
Audio signal is prestored, it is the identifiable audio signal of terminal, such as the capable of speech in language assists that this, which prestores audio signal,
The information perhaps speech-controlled information in types of applications program or terminal unlocking control information etc..Processing module gets logical
Cross microphone module acquisition the first audio signal after, processing region by the first audio signal and prestore audio signal it is luxuriant into
Row compares, and screens out in the first audio-frequency information and prestores the consistent audio signal of audio signal.
In other embodiments of the invention, prestore audio signal can also include the voice signal that is identified to terminal into
The sorted audio signal of row, such as audio signal is prestored using voice assistant class as first prestored in audio signal, it will lead to
Class is interrogated as second prestored in audio signal and prestores audio signal etc..Processing module is to the first audio-frequency information and prestores audio
When signal is compared, audio signal can be prestored with first one by one, second the content in audio signal is prestored and is compared, is confirmed
Which kind of audio signal is first audio signal belong to.For example, microphone collects when user uses voice assistant function in advance
Sound be " open Amap ", and be processed into the first audio signal, and first prestore sound in prestoring audio signal
Inquired in frequency signal with the consistent audio signal of the first audio signal " open Amap ", then being confirmed as the audio signal is
Effective audio signal, and be voice assistant class audio frequency signal.
Step S3022: being screened by the processing module in microphone and prestore consistent second audio signal of audio signal,
And the second audio signal is stored to the processing module into microphone.
In embodiments of the present invention, this prestore audio signal be the identifiable audio signal of terminal, processing module pass through by
First audio signal is compared with audio signal is prestored, and the first audio signal of confirmation is effective audio signal, then by this audio
Signal stores the storage region into processing module as the second audio signal.
In other embodiments of the invention, it prestores after audio signal classifies for the voice signal identified to terminal
Audio signal, such as prestore audio signal for voice assistant class as first prestored in audio signal, using communication class as
Second prestored in audio signal prestores audio signal etc..Processing module is by the first audio signal and will prestore audio signal
It is compared, if the audio-frequency information that the first audio signal of confirmation is prestored with first in audio signal matches, this audio is believed
Number the storage region into processing module is stored as the second audio signal plus the first identification information for prestoring audio.
Similarly, if the audio-frequency information that the first audio signal of confirmation is prestored with second in audio signal matches, by this audio signal
In addition second prestores the identification information of audio, as the second audio signal, the storage region into processing module is stored.Example
Such as, when user uses voice assistant function in advance, the collected sound of microphone is " opening Amap ", and is processed into
First audio signal, and first prestore and inquired in audio signal and the consistent sound of the first audio signal in prestoring audio signal
Frequency signal " open Amap ", then the voice assistant class mark that the audio signal prestores audio-frequency information plus first, as the
Two audio signals store the storage region into processing module.
Referring to Fig. 6, Fig. 6 is a kind of flow diagram three of audio-frequency processing method provided in an embodiment of the present invention, it is pair
The further refinement of step S303, as shown, method includes the following steps:
Step S3031: the second audio-frequency information is sent to the processor of terminal.
In embodiments of the present invention, the processing module in microphone will carry out pretreated second audio-frequency information and be sent to
The processor of terminal.
Step S3032: the second audio signal is handled using processor.
It in embodiments of the present invention, can be to the second audio signal after the processor of terminal receives the second audio signal
It skips and judges whether the audio signal is the treatment process of effective audio signal, and be directly further processed, by second
Audio signal is matched with specific operation.
In other embodiments of the invention, if if without identification information in the second audio signal, using processor
Classification searching is carried out to the second audio signal, which kind of phonetic function in its terminal determined, by the second audio signal pair after determining
The feature operation answered is matched, and executes the operational order.If there are identification informations in the second audio signal, can be direct
It is matched with corresponding function operation, executes the operational order.For example, when user uses voice assistant function in advance, wheat
Gram collected sound of wind is " opening Amap ", and is processed into the first audio signal, and in prestoring audio signal
