Equal elastic fluids can also transmit sound, and sound is 333 meters per second propagating in air, and when sound passes under water
Sowing time, because Media density becomes larger, the speed that sound is propagated in water is more faster than propagating in air, such as sound
Sound is 1455 meters per second in the speed of light water transmission.
In addition, since spread speed of the sound in different propagation mediums is different, so, sound is situated between in different propagation
It is different that the time used in same distance is propagated in matter.Thus, the embodiment of the present invention, by obtaining a voice signal mobile whole
It holds in the propagation medium being presently in, propagates the propagation time of a pre-determined distance, and then judge movement eventually according to the propagation time
Whether end is in water.Wherein, the pre-determined distance is that the voice signal from the loudspeaker of the mobile terminal is issued to institute
State the distance propagated when the microphone reception of mobile terminal.
Step 102: according to the propagation time, judging whether the mobile terminal is in water.
When propagation distance is identical, the different propagation times corresponds to different propagation mediums, thus, reality of the invention
The propagation time of the pre-determined distance can be propagated according to voice signal in the propagation medium that mobile terminal is presently in by applying example,

Second embodiment
The embodiment provides a kind of mode switching methods of mobile terminal, as shown in Fig. 2, this method comprises:
Step 201: obtaining a voice signal in the propagation medium that mobile terminal is presently in, propagate a pre-determined distance
Propagation time.
Wherein, spread speed of the sound in different propagation mediums is different.For example, in addition to air, water, metal, wood
Equal elastic fluids can also transmit sound, and sound is 333 meters per second propagating in air, and when sound passes under water
Sowing time, because Media density becomes larger, the speed that sound is propagated in water is more faster than propagating in air, such as sound
Sound is 1455 meters per second in the speed of light water transmission.
In addition, since spread speed of the sound in different propagation mediums is different, so, sound is situated between in different propagation
The difference of time used in same distance is propagated in matter, i.e., in the different propagation times, corresponds to different propagation mediums.Thus, this
The embodiment of invention propagates a pre-determined distance by obtaining a voice signal in the propagation medium that mobile terminal is presently in
Propagation time, and then judge whether mobile terminal is in water according to the propagation time.
Wherein, the pre-determined distance be the voice signal from the loudspeaker of the mobile terminal be issued to it is described it is mobile eventually
The distance that the microphone at end is propagated when receiving, i.e., the described pre-determined distance is that the setting position of the loudspeaker on mobile terminals is arrived
The distance between the setting position of the microphone on the mobile terminal.
As shown in figure 3, the transmission of voicefrequency circuit and external agency inside mobile terminal 300 constitutes returning for a closed loop
Sound picks up detection path.It is assumed that the voicefrequency circuit inside mobile terminal is by audio A/D converter, audio processing modules and audio
Three module compositions of codec (specific composition of the audio talk-back circuit inside practical different mobile terminal has difference), then
The voice signal issued by audio processing modules picks up measure loop " reflux " to audio processing modules eventually by this echo,
And there are certain time delays 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, and the when a length of t3 in audio codec, then when mobile terminal be in water, echo, which is picked up, to be detected
The overall delay T1=t1+t2+t3+tw of access, wherein tw be sound in water from loudspeaker 302 travel to microphone 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, wherein ta is sound
The time delay of microphone 301 is traveled to from loudspeaker 302 in air.
Wherein, since the voicefrequency circuit inside mobile terminal does not change, the time delay master of detection path is picked up in echo
The difference wanted is that the speed propagated in sound in external agency is variant.So by detecting mobile terminal external communication medium
Time delay, in conjunction with the spacing of microphone 301 and loudspeaker 302 on mobile terminal and the ratio between the spread speed of sound wave in water,
It can judge transmission medium.
Since the microphone and loudspeaker position of the mobile terminal of each model are fixed, then the pre-determined distance is just
It is fixed, thus only needs to calibrate every mobile terminal when leaving the factory and propagate the propagation time of pre-determined distance in water as mark
Quasi- value, so that it may judge whether mobile terminal is in water.I.e. previously according to the spacing and sound of microphone and loudspeaker
Spread speed in water calculates the standard value in the propagation time of sound in water, and then the actually detected sound arrived is believed
Number it is issued to the received time interval of microphone from loudspeaker, is compared with the standard value, to judge that mobile terminal is
It is no to be in water.
Preferably, before step 201, the embodiment of the present invention further include: whether detection mobile terminal generates mode knowledge
It does not instruct, and when detecting pattern-recognition instruction, executes and obtain the biography that a voice signal is presently in mobile terminal
The step of broadcasting in medium, propagating the propagation time of a pre-determined distance.I.e. when mobile terminal generates pattern-recognition instruction, just start
Propagation medium locating for mobile terminal is detected, to save electricity.
Specifically, an overboard detection switch can be set on mobile terminals, it is mobile after the overboard detection switch is opened
Terminal generates pattern-recognition instruction；Alternatively, mobile terminal generates when detecting the default slide of user on mobile terminals
Pattern-recognition instruction；Alternatively, when detecting that the predetermined physical key of mobile terminal or default combination button are pressed, mobile terminal
Generate pattern-recognition instruction.
Moreover it is preferred that step 201 includes: to control the loudspeaker sending of the mobile terminal according to prefixed time interval
One voice signal, and tracer signal issues the moment；When the propagation medium that the voice signal is presently in through the mobile terminal
When traveling to the microphone of the mobile terminal, the tracer signal time of reception；The signal time of reception subtracts the signal hair
Moment out obtains the propagation time.
That is, the embodiment of the present invention, is not only to obtain a voice signal to be situated between in the propagation that mobile terminal is presently in
When being propagated in matter the propagation time of the pre-determined distance, but obtaining the primary propagation according to predetermined time interval
Between, i.e., according to prefixed time interval, detected to whether mobile terminal is in water.Wherein, poll detection purpose be for
Power saving.
In addition, control loudspeaker issues a voice signal, and records at this time when reaching whenever the prefixed time interval
At the time of, then, when microphone receives the voice signal, at the time of record again at this time, and then calculates and obtain two
Time interval between at the time of secondary recorded.Calculating the time interval obtained is exactly the voice signal outside mobile terminal
The propagation time propagated in transmission medium.
Step 202: according to the propagation time, judging whether the mobile terminal is in water.
Preferably, step 202 includes: to judge whether the absolute value of the difference of the propagation time and the first standard value is in the
Within one preset range；When the absolute value of the difference of the propagation time and first standard value is in first preset range
Within when, determine that the mobile terminal is in water；Wherein, first standard value is that the predetermined voice signal exists
The propagation time of pre-determined distance described in water transmission.
Wherein, first standard value is predetermined.Specifically, when the pre-determined distance be the voice signal from
The loudspeaker of the mobile terminal be issued to the mobile terminal microphone receive when propagate apart from when, i.e., it is described first mark
Quasi- value be setting the distance between the position and the setting position of loudspeaker on mobile terminals of microphone on mobile terminals with
The ratio between the spread speed of sound in water.That is the first standard value Tw=L/Vw, wherein L is the pre-determined distance, and Vw is that sound exists
Spread speed in water.
In addition, the speed due to sound transmission is influenced by the salinity of water, temperature and pressure, so, according to sound
Signal in the propagation medium outside mobile terminal from loudspeaker pass to microphone used in propagation time Tx and described
One standard value Tw when judging whether mobile terminal is in water, needs to reserve certain fluctuation range, for example, when 80%Tw < Tx <
120%Tw, i.e., | Tx-Tw | when < 20%Tw, it can determine that mobile terminal is in water, whether judge mobile terminal to increase
Accuracy in water.
In addition, voice signal is in actual propagation path, since microphone and loudspeaker are all in mobile terminal inside,
Echo picks up detection path and further comprises the path transmitted by mobile terminal shell itself.Wherein, sound is in solids
Spread speed range between 2km/s to 6km/s, the speed be much larger than the spread speed of sound in water.Specifically, with sound
The spread speed of sound in solids with the 2km/s of most lower limit, counted as follows by taking 1500m/s as an example by spread speed in water
It calculates:
Tx=(L ÷ 2000m/s) ÷ (L ÷ 1500m/s)=75%Tw.
It is pre- to be unsatisfactory for first by the echo that mobile terminal shell circuit generates by so Tx-Tw=25%Tw > 20%Tw
If range: | Tx-Tw | < 20%Tw.Thus, the embodiment of the present invention, by the way that first preset range is rationally arranged, Bu Huiyin
For there are voice signals in mobile terminal shell from loudspeaker pass to microphone, and cause to judge by accident.
Further, the interference of mobile terminal shell bring can be also eliminated by way of signal strength detection.Wherein, sound
The intensity that sound is propagated by shell will be much smaller than the intensity of external agency, and certain grade is not achieved in echo intensity, therefore, in wheat
When gram wind receives the voice signal, whether the intensity that can further detect the voice signal that microphone receives reaches default
Intensity threshold could execute step 202 or step 204 when reaching the intensity threshold.
Step 203: when the mobile terminal is in water, the use pattern of the mobile terminal being switched to underwater
Use pattern.
When judging that mobile terminal is in water by step 202, the embodiment of the present invention, automatically by mobile terminal
Use pattern is switched to underwater use pattern, allows user that can directly use mobile terminal under water.
Step 204: according to the propagation time, judging whether the mobile terminal is in air.
Preferably, step 204 includes: to judge whether the absolute value of the difference of the propagation time and the second standard value is in the
Within two preset ranges；When the absolute value of the difference of the propagation time and second standard value is in second preset range
Within when, determine that the mobile terminal is in air；Wherein, second standard value is the predetermined voice signal
The propagation time of the pre-determined distance is propagated in air.
Wherein, second standard value is predetermined.Specifically, when the pre-determined distance be the voice signal from
The loudspeaker of the mobile terminal be issued to the mobile terminal microphone receive when propagate apart from when, i.e., it is described second mark
Quasi- value be setting the distance between the position and the setting position of loudspeaker on mobile terminals of microphone on mobile terminals with
The ratio between aerial spread speed of sound.That is the second standard value Ta=L/Va, wherein L is the pre-determined distance, and Va is sound
Aerial spread speed.
In addition, the speed due to sound transmission is influenced by the temperature, humidity, pressure of air, so, according to voice signal
In the propagation medium outside mobile terminal from loudspeaker pass to microphone used in propagation time Tx and it is described second mark
Quasi- value Ta when judging whether mobile terminal is in air, needs to reserve certain fluctuation range, i.e., exhausted when the difference of Tx and Ta
When to value within the second preset range, it can determine that mobile terminal comes back in air, so that it is mobile eventually to increase judgement
Whether end is in the accuracy in air.
Step 205: when the mobile terminal is in air, the use pattern of the mobile terminal being switched to air
In use pattern.
In an embodiment of the present invention, it can not only detect automatically whether mobile terminal is in water, and can be automatic
Whether detection mobile terminal is in air, so as to which in mobile terminal, from when moving on in air in water, mobile terminal can
The use pattern in air is automatically switched to, the usage experience of user is further promoted.
In conclusion the embodiment of the present invention, by being situated between according to a voice signal in the propagation that mobile terminal is presently in
In matter, the propagation time used in a pre-determined distance is propagated, to judge whether the mobile terminal is currently in water, and then is being judged
When the mobile terminal is in water out, the use pattern of mobile terminal is switched to underwater use pattern, and can also root
Judge whether mobile terminal is in air according to the propagation time, and when judging in air, mobile terminal is cut
Change to the use pattern in air.
It follows that the embodiment of the present invention, does not need additionally to increase other accessories on mobile terminals, and do not need to use
Family is carried out complicated operation and is passed in water in conjunction with transmission path of the voice signal from loudspeaker pass to microphone using sound wave
The speed principle different with spread speed in air is broadcast, media environment locating for mobile terminal is distinguished, enables mobile terminal
Enough automatic detections and to the use pattern corresponded in locating media environment is entered, simplify the operating process of user, are promoted
The usage experience of user carries out the cumbersome problem of pattern switching when solving mobile terminal and entering underwater operation.
