Second embodiment
The embodiment provides a kind of mode switching method of mobile terminal, as shown in Fig. 2 the method includes:
Step 201: obtain an acoustical signal in the propagation medium that mobile terminal is presently in, propagate a predeterminable range
Propagation time.
Wherein, spread speed in different propagation mediums for the sound is different.For example, except air, water, metal, wood
Also sound can be transmitted Deng elastic fluid, and sound is propagating in atmosphere as 333 meters per second, and work as sound and pass under water
Sowing time, because Media density becomes big, sound propagates faster, such as sound in the speed of water transmission than in atmosphere
Sound is 1455 meters per second in the speed of light water transmission.
Further, since spread speed in different propagation mediums for the sound is different, so, sound is situated between in different propagation
The time propagated in matter used by same distance is different, i.e. the different propagation time, correspond to different propagation mediums.Thus, this
Inventive embodiment, by obtaining an acoustical signal in the propagation medium that mobile terminal is presently in, propagates a predeterminable range
Propagation time, and then judge according to the propagation time whether mobile terminal is in water.
Wherein, described predeterminable range is that described acoustical signal is issued to described movement eventually from the speaker of described mobile terminal
The distance that the mike at end is propagated when receiving, that is, described predeterminable range is that described speaker set location on mobile terminals arrives
The distance between described mike set location on the mobile terminal.
As shown in figure 3, the transmission of voicefrequency circuit within mobile terminal 300 and external agency constitutes returning of a closed loop
Sound picks up detection path.It is assumed that the voicefrequency circuit within mobile terminal is by audio A/D converter, audio processing modules and audio frequency
Three module compositions of codec (the concrete composition of the audio frequency talk-back circuit within actual different mobile terminal has difference), then
The acoustical signal being sent by audio processing modules picks up measure loop " backflow " to audio processing modules eventually through this echo,
And there is certain time delay in each link.For example, the time delay in audio A/D converter is t1, in Audio Processing mould
Time delay in block is t2, the when a length of t3 in audio codec, then when mobile terminal is in water, echo pickup detection
The overall delay t1=t1+t2+t3+tw of path, wherein, tw be sound in water from speaker 302 travel to mike 301 when
Prolong；When mobile terminal is in air, the overall delay t2=t1+t2+t3+ta of detection path is picked up in echo, and wherein, ta is sound
Travel to the time delay of mike 301 in atmosphere from speaker 302.
Wherein, because the voicefrequency circuit within mobile terminal is not changed in, the time delay master of detection path is picked up in therefore echo
The difference wanted is variant in the speed of outside Medium Propagation in sound.So, by detecting mobile terminal external communication medium
Time delay, in conjunction with the ratio of spacing spread speed in water with sound wave of mike on mobile terminal 301 and speaker 302,
Just can interpolate that out transmission medium.
Because the mike of the mobile terminal of each model and loudspeaker position are fixing, then described predeterminable range is just
It is fixing, thus only need to calibrate the propagation time in water transmission predeterminable range for the every mobile terminal when dispatching from the factory as mark
Quasi- value is it is possible to judge whether mobile terminal is in water.I.e. previously according to the spacing of mike and speaker, and sound
Spread speed in water, calculates the standard value in propagation time in water for the sound, and then the actually detected sound arriving is believed
Number from speaker be issued to mike reception time interval, compare with this standard value, thus judging that mobile terminal is
No it is in water.
Preferably, before step 201, embodiments of the invention also include: detection mobile terminal whether know by generation mode
Do not instruct, and when described pattern recognition instruction is detected, execution obtains the biography that an acoustical signal is presently in mobile terminal
Broadcast in medium, the step propagating the propagation time of a predeterminable range.I.e. in the identification instruction of mobile terminal generation mode, just start
Propagation medium residing for detection mobile terminal, thus save electricity.
Specifically, an overboard detection switch can be set on mobile terminals, after this overboard detection switch is opened, mobile
The identification instruction of terminal generation mode；Or, when user's default slide on mobile terminals is detected, mobile terminal generates
Pattern recognition instructs；Or, the predetermined physical button of mobile terminal is detected or when default combination button is pressed, mobile terminal
Generation mode identification instruction.
Moreover it is preferred that step 201 includes: according to prefixed time interval, control the speaker of described mobile terminal to send
One acoustical signal, and tracer signal sends the moment；The propagation medium being presently in through described mobile terminal when described acoustical signal
Travel to described mobile terminal mike when, the tracer signal time of reception；The described signal time of reception deducts described signal and sends out
Go out the moment, obtain the described propagation time.
That is, embodiments of the invention, are not that the propagation that only acoustical signal of acquisition is presently in mobile terminal is situated between
When propagating in matter the propagation time of described predeterminable range, but obtaining once described propagation according to predetermined time interval
Between, that is, according to prefixed time interval, detect to whether mobile terminal is in water.Wherein, poll detection purpose be for
Power saving.
In addition, when reaching whenever described prefixed time interval, controlling loudspeaker sends an acoustical signal, and records now
Moment, then, when mike receives this acoustical signal, record the moment now again, so calculate acquisition two
Time interval between secondary the recorded moment.Calculating the time interval obtaining is exactly this acoustical signal outside mobile terminal
The propagation time propagated in transmission medium.
Step 202: according to the described propagation time, judge whether described mobile terminal is in water.
Preferably, step 202 includes: judges whether the absolute value of the difference of described propagation time and the first standard value is in the
Within one preset range；When the absolute value in described propagation time and the difference of described first standard value is in described first preset range
Within when, determine that described mobile terminal is in water；Wherein, described first standard value exists for predetermined described acoustical signal
The propagation time of predeterminable range described in water transmission.
Wherein, described first standard value is predetermined.Specifically, when described predeterminable range be described acoustical signal from
The speaker of described mobile terminal be issued to described mobile terminal mike receive when propagate apart from when, that is, described first mark
Standard be worth for the distance between mike set location on mobile terminals and speaker set location on mobile terminals with
The ratio of spread speed in water for the sound.I.e. the first standard value tw=l/vw, wherein, l is described predeterminable range, and vw exists for sound
Spread speed in water.
Further, since the speed of sound transmission is affected by the salinity of water, temperature and pressure, so, according to sound
Propagation time tx used by from loudspeaker pass to mike and described in propagation medium outside in mobile terminal for the signal
One standard value tw, when judging whether mobile terminal is in water, needs reserved certain fluctuation range, for example when 80%tw < tx <
120%tw, that is, whether | tx-tw | is < it may be determined that mobile terminal is in water during 20%tw, thus increase judge mobile terminal
It is in the accuracy in water.
Additionally, acoustical signal is in actual propagation path, because mike and speaker are all in mobile terminal inside,
Echo is picked up detection path and be further comprises a path passing through mobile terminal shell transmission itself.Wherein, sound is in solids
Spread speed scope between 2km/s to 6km/s, this speed be much larger than spread speed in water for the sound.Specifically, with sound
Sound spread speed in solids, with the 2km/s of lower limit, is counted in the spread speed in water taking 1500m/s as a example as follows
Calculate:
Tx=(l ÷ 2000m/s) ÷ (l ÷ 1500m/s)=75%tw.
So tx-tw=25%tw > 20%tw, is unsatisfactory for first by the echo that mobile terminal shell loop produces pre-
If scope: | tx-tw | < 20%tw.Thus, embodiments of the invention, by reasonable, described first preset range, Bu Huiyin are set
For there is acoustical signal in mobile terminal shell from loudspeaker pass to mike, and lead to judge by accident.
Further, the interference that mobile terminal shell is brought can also be eliminated by way of signal strength detection.Wherein, sound
The intensity that sound is propagated by housing will be much smaller than the intensity of external agency, and echo intensity does not reach certain grade, therefore, in wheat
When gram wind receives described acoustical signal, can detect whether the intensity of the acoustical signal that mike receives reaches further default
Intensity threshold, when reaching described intensity threshold, could execution step 202 or step 204.
Step 203: when described mobile terminal is in water, the use pattern of described mobile terminal is switched under water
Use pattern.
When judging that mobile terminal is in water by step 202, embodiments of the invention, automatically by mobile terminal
Use pattern switches to use pattern under water so that user can under water can be directly using mobile terminal.
Step 204: according to the described propagation time, judge whether described mobile terminal is in the air.
Preferably, step 204 includes: judges whether the absolute value of the difference of described propagation time and the second standard value is in the
Within two preset range；When the absolute value in described propagation time and the difference of described second standard value is in described second preset range
Within when, determine that described mobile terminal is in the air；Wherein, described second standard value is predetermined described acoustical signal
Propagate the propagation time of described predeterminable range in atmosphere.
Wherein, described second standard value is predetermined.Specifically, when described predeterminable range be described acoustical signal from
The speaker of described mobile terminal be issued to described mobile terminal mike receive when propagate apart from when, that is, described second mark
Standard be worth for the distance between mike set location on mobile terminals and speaker set location on mobile terminals with
The ratio of the aerial spread speed of sound.I.e. the second standard value ta=l/va, wherein, l is described predeterminable range, and va is sound
Aerial spread speed.
Further, since the speed of sound transmission is affected by the temperature of air, humidity, pressure, so, according to acoustical signal
Propagation time tx used by from loudspeaker pass to mike and described second mark in propagation medium outside in mobile terminal
Accurate value ta, when judging whether mobile terminal is in the air, needs to reserve certain fluctuation range, that is, when tx and ta difference exhausted
It may be determined that mobile terminal comes back in the air when being in value within the second preset range, thus it is mobile eventually to increase judgement
Whether end is in the accuracy of in the air.
Step 205: when described mobile terminal is in the air, the use pattern of described mobile terminal is switched to air
In use pattern.
In an embodiment of the present invention, can not only automatic detection mobile terminal whether be in water, and can be automatic
Whether detection mobile terminal is in the air such that it is able to when mobile terminal moves on in the air from water, mobile terminal can
Automatically switch to the use pattern of in the air, lift the experience of user further.
In sum, embodiments of the invention, by being situated between according to the propagation that an acoustical signal is presently in mobile terminal
In matter, propagate the propagation time used by a predeterminable range, to judge whether this mobile terminal is currently in water, and then judging
When going out this mobile terminal and being in water, the use pattern of mobile terminal is switched to use pattern under water, and also being capable of root
Judge whether mobile terminal is in the air according to the described propagation time, and when judging to be in the air, mobile terminal is cut
Change to the use pattern of in the air.
It follows that embodiments of the invention are it is not necessary to additionally increase other accessories on mobile terminals, and do not need to use
Family carries out the operation of complexity, in conjunction with transmission path from loudspeaker pass to mike for the acoustical signal, is passed in water using sound wave
Broadcast the speed principle different with the air spread speed, distinguish media environment residing for mobile terminal so that mobile terminal energy
Reach automatic detection and to entering into corresponding to the use pattern in residing media environment, simplify the operating process of user, lifting
The experience of user, when solving mobile terminal and entering underwater operation, carries out the loaded down with trivial details problem of pattern switching.
