Based on above-mentioned mobile terminal hardware configuration and communication system, each embodiment of the inventive method is proposed.
The flow chart of whole audio amplifying method one embodiment is moved as it is shown on figure 3, Fig. 3 is the present invention.
The audio amplifying method of the mobile terminal of this enforcement, comprises the steps:
Step S10, receive speakerphone mode trigger signal time, start speakerphone mode.
Specifically, described mobile terminal includes mobile phone, panel computer etc..Specifically say as a example by mobile phone
Bright.The trigger module for triggering speakerphone mode can be provided with in mobile phone；Mobile phone desktop is provided with corresponding institute
State the icon of trigger module；When user needs to use speakerphone mode, then can click directly on mobile phone desktop
On icon, to trigger speakerphone mode.
Step S20, the acoustical signal gathered in environment, and from described acoustical signal, obtain the voice of user
Signal.
Concrete, after user starts speakerphone mode, the transmitter of mobile phone automatically opens up, and starts to adopt
The acoustical signal of collection user, then obtains the voice signal of user from described acoustical signal.
As shown in Figure 4, the step of the described voice signal obtaining user in acoustical signal specifically includes:
Step S21, judge whether described acoustical signal is voice signal.
Concrete, it is judged that described acoustical signal be whether the concrete mode of voice signal can be Application on Voiceprint Recognition,
Frequency spectrum discernings etc., this function can be realized by the CPU of mobile phone, it is not necessary to increases and identifies device, will not
Increase the cost of mobile phone.
If it is, perform step S22, obtain the described acoustical signal voice signal as user, in case
Follow-up it is amplified.
If fruit is the most no, then performs step S23, filter out described acoustical signal, to avoid follow-up amplified
Journey is amplified this acoustical signal, interferes.
Step S30, the voice signal got is amplified, and exports.
Specifically, voice signal is amplified and the pattern at least two kinds that exports: one is to pass through hands
Machine and external audio equipment wireless connections (including bluetooth, WIFI etc.), the signal after amplifying exports extremely
External audio equipment；Another way is at the bigger speaker of embedded in mobile phone power, after directly amplifying
Signal have speaker to export.
The technical scheme of the present embodiment, by after triggering speakerphone mode, gathers the acoustical signal of user,
And obtain the voice signal in acoustical signal, export after being then amplified voice signal processing so that
Mobile terminal achieves sound amplification function so that the mobile terminal carried with can amplify whenever and wherever possible, just
The property taken is good, solves a lot of meeting and leaves behind the embarrassment of mike；Meanwhile, utilize mobile terminal existing capability,
In the case of not increasing cost, it is provided that new use field, bring the lifting of Consumer's Experience.
Further, as it is shown in figure 5, Fig. 5 is the present invention moves whole another embodiment of audio amplifying method
Flow chart.
Based on above-described embodiment, in the present embodiment, the audio amplifying method of described mobile terminal amplifies in startup
After the step of pattern, also include:
Whether step S40, detection mobile terminal are in inversion state.
Specifically, after user triggers speakerphone mode, then can be by detection handss such as gyro sensors
The state that machine is presently in.Wherein, the state that mobile phone is presently in includes just putting (namely the head of mobile phone
Place upward), horizontal (namely mobile phone horizontal positioned) or be inverted (namely the head of mobile phone place down).
When mobile phone slant setting, can according to user angle of inclination etc. arranged correspondence just put, horizontal or
In the range of inversion.
If it is, perform step S20, gather the acoustical signal in environment, and obtain from described acoustical signal
Take the voice signal at family.
Specifically, when mobile phone is in inversion state, then judge that user is currently in use sound amplification function, at this moment,
The transmitter of mobile phone automatically opens up, and starts the acoustical signal number gathering in environment.
If it is not, then perform step S50, stop gathering the acoustical signal in environment.
Specifically, when mobile phone is in non-inverted state (namely just putting or horizontal) state, then hands is closed
The transmitter of machine, stops gathering the acoustical signal in environment.Such as, when classroom or meeting take a break,
Then by mobile phone horizontal or just can put, at this moment, the transmitter of mobile phone is automatically switched off, no longer the sound in environment
Tone signal, namely suspend the sound amplification function of mobile phone so that mobile phone sound amplification function is humanized.
Further, as shown in Figure 6, Fig. 6 is the voice signal collected to be amplified step one in fact
Execute the particular flow sheet of example.
Based on above-described embodiment, in the present embodiment, the described voice signal to getting is amplified,
And the concrete steps carrying out exporting include:
Step S31, the voice signal got is converted to the signal of telecommunication.
Specifically, when after the voice signal getting user, the voice signal that the CPU of mobile phone will get
Carry out translation operation, to convert voice signals into the signal of telecommunication.
Step S32, the signal of telecommunication is amplified process.
Specifically, after the CPU of mobile phone converts voice signals into the signal of telecommunication, by the amplification electricity of mobile phone
The signal of telecommunication is amplified by roads etc..
Step S33, will amplify after the signal of telecommunication be converted to the air analog signal that stereo set can identify.
Specifically, after the signal of telecommunication is amplified by the amplifying circuit of mobile phone, after the CPU of mobile phone will amplify
The signal of telecommunication carry out translation operation, with will amplify after the signal of telecommunication be converted to air analog signal.In mobile phone
Wireless device (such as blue-tooth device, WIFI device etc.) by air analog signal output to the most external sound equipment
Equipment, and then realize the sound amplification function of mobile phone.
Further, as it is shown in fig. 7, Fig. 7 be the voice signal collected is amplified step another
The particular flow sheet of embodiment.
Based on above-described embodiment, in the present embodiment, the described voice signal to getting is amplified
Concrete steps include:
