Sound 2 hours, to effectively prevent the case where recording pen leads to not recording because of the not enough power supply of internal battery.
Based on above-mentioned recording pen, the embodiment of the present application also provides a kind of ways of recording.Next, in conjunction with attached drawing 7, to this
The application way of recording is introduced, as shown in fig. 7, this method comprises:
Step S700, when detecting that the fingerprint key is correctly triggered, the microphone array and described fixed is controlled
Start to record to microphone.
Specifically, when user needs to record, can touch by fingerprint key, thus this step can detect fingerprint by
When key is correctly triggered, controls microphone array and shotgun microphone starts to record.
Above-mentioned fingerprint key is by correctly currently collected fingerprint and the application are pre-stored for triggering Characterize fingerprints key
Fingerprint is identical, so that it is lawful acts that characterization, which starts recording based on above-mentioned collected fingerprint,.
Step S710, the analog audio signal that the microphone array and the shotgun microphone acquire is converted to first
Digital audio and video signals.
Specifically, after microphone array starts recording, the short distance voice data of acquisition is analog audio signal, similarly fixed
After starting recording to microphone, the remote voice data of acquisition is also analog audio signal.Then this step can be by microphone
Array and the analog audio signal of shotgun microphone acquisition are converted to the first digital audio and video signals, so that subsequent processing is recorded
Data.Here the first digital audio and video signals are that above-mentioned recording pen sound intermediate frequency coding module 4 is based on microphone array 2 and orientation wheat
The digital audio and video signals for the analog audio signal conversion that gram wind 3 acquires.
Step S720, first digital audio and video signals are handled, recording data is obtained.
Specifically, this step can be handled above-mentioned first digital audio and video signals, to obtain recording data.
The process that this step handles above-mentioned first digital audio and video signals is handled with processing circuit 5 in above-mentioned recording pen
The process of digital audio and video signals is corresponding, can refer to foregoing description in detail, is no longer described in detail herein.
The embodiment of the present application can by microphone array acquire short distance voice data, the short distance voice data for
Noise reduction uses, and the recording data obtained based on the short distance voice data is in subsequent progress speech recognition and text transcription
Accuracy is higher.Further, it is also possible to acquire remote voice data by shotgun microphone, obtained based on the remote voice data
The recording data fidelity arrived is higher, more can clearly restore recording site, while obtained recording data sense of hearing is more preferable.Cause
This, is recorded by microphone array and shotgun microphone, and radio reception effect is more preferable.Further, the application can pass through fingerprint
Key is correctly triggered, and is realized one-key start recording pen and is started the function of recording, so as to more convenient and more pacify
Entirely.
Above-mentioned recording pen may include display screen, so that display uses.Based on this, the embodiment of the present application is to above-mentioned steps
S700 controls the microphone array and the shotgun microphone starts when detecting that the fingerprint key is correctly triggered
The process of recording is illustrated.
Above-mentioned steps S700 controls the microphone array and institute when detecting that the fingerprint key is correctly triggered
Stating shotgun microphone to start the process of recording may include at least one of following two ways:
The first:
When determining that display screen is in black state, if detecting, the fingerprint key is correctly triggered, described in control
Microphone array and the shotgun microphone start to record；
Specifically, display screen may be at black state and bright screen state.Under normal circumstances, display screen is in black state
When, recording pen may be at standby mode, to reduce the power consumption of recording pen；When display screen is in bright screen state, recording pen can be with
It is in running order.
At present in the case where recording pen is in open state and display screen is in black state, when user want by recording pen into
When row recording, it usually needs first display screen is switched to bright screen state from black state, so that recording pen, which is in, to record
Then working condition searches in recording pen and triggers record button and realizes sound-recording function.Compared with the prior art, the application is implemented
Example can be when display screen be in black state, if detecting, fingerprint key is correctly triggered, and controls microphone array and orientation
Microphone starts to record, to realize that the lower key of black state starts the function of recording.It will first be shown since the process eliminates
Screen is converted to the process that bright screen state is recorded again by black state, so that more convenient when user is using recording pen.
Second:
When determining that display screen is in bright screen state, if detecting, the fingerprint key is correctly triggered, described in control
Microphone array and the shotgun microphone start to record.
The embodiment of the present application can be when display screen be in bright screen state, if detecting, fingerprint key is correctly triggered, control
Microphone array and shotgun microphone processed start to record, to realize that the lower key of bright screen state starts the function of recording, user makes
It is more convenient when with recording pen.
Above-mentioned recording pen can also include loudspeaker, which is used for playing audio-fequency data.The application can be by loudspeaking
The analog audio signal that device plays is converted to the second digital audio and video signals, and as echo cancellation reference signal, to eliminate
Echo data in first digital audio and video signals.Here the second digital audio and video signals are above-mentioned recording pen sound intermediate frequency coding module
The digital audio and video signals of the 4 analog audio signal conversions played based on loudspeaker.Based on this, one embodiment of the application is right
Above-mentioned steps S720, handles first digital audio and video signals, and the process for obtaining recording data is illustrated.

To include:
Based on the echo cancellation reference signal, noise reduction is carried out to first digital audio and video signals, after obtaining noise reduction
Recording data.
Specifically, the first digital audio and video signals may include the corresponding digital audio and video signals of echo data, need to this time
The corresponding digital audio and video signals of sound data carry out Processing for removing, to obtain the higher recording data of fidelity.
Based on this, the embodiment of the present application can be based on the corresponding echo cancellor of audio data that loudspeaker plays with reference to letter
Number, noise reduction is carried out to the first digital audio and video signals, to obtain the recording data after noise reduction, the fidelity of the recording data is more
Height, and clearer live recording can be restored.
This step carries out the process of noise reduction to the first digital audio and video signals and processing circuit 5 in above-mentioned recording pen is based on and raises
Digital audio and video signals corresponding with microphone array 2 and shotgun microphone 3 drop in the corresponding digital audio and video signals of sound device
The process made an uproar is corresponding, can refer to foregoing description in detail, is no longer described in detail herein.
