The impact of the second radiating block 33.
On the architecture basics of mobile terminal in the aforementioned embodiment, it is also possible to by certain heat dissipating method to mobile whole
End dispels the heat.Fig. 4 is the schematic flow sheet of the mobile terminal heat dissipating method that the embodiment of the present invention two provides.As shown in Figure 4, originally
The mobile terminal heat dissipating method that embodiment provides, is applied on the mobile terminal in previous embodiment, and specifically includes following step
Rapid:
The duty of the speaker in S101, detection mobile terminal.
Concrete, the speaker in mobile terminal both can carry out normal sound broadcasting, it is also possible to sends and can promote shifting
The sound wave of sound chamber air flowing is gone out before dynamic terminal.During because speaker carries out normal sound broadcasting, if superposition is used for producing again
The audio signal of raw sound wave, can interfere sound result of broadcast, and when normal sound is play, it may have certain promotion is empty
The effect of flow of air, so before sending the sound wave being specifically designed to promotion air flowing, raising one's voice in needing to detect mobile terminal
Whether device is in normal work, if speaker is carrying out the broadcasting of normal sound signal, does not the most send special
Promote the audio signal of air flowing.
S102, when speaker is idle condition, control speaker send audio signal, to go out before promoting mobile terminal
The air flowing of sound intracavity, and take away and produced by the heat source component of mobile terminal and conduct to the heat front going out sound intracavity.
When speaker is positioned at idle condition, when the most not carrying out normal sound playing function, should control in mobile terminal
Speaker sends audio signal, goes out air in sound chamber and produces flowing, then pass through mobile terminal before promoting within mobile terminal
Sender flow out, heat source component is produced simultaneously, and conducts extremely the most front to go out the heat of sound intracavity and take out of inside mobile terminal, for
Mobile terminal plays radiating effect.
The executive agent of said method can be the main control chip within mobile terminal, it is also possible to for being independently arranged or whole
It is combined on the internal mainboard of mobile terminal, for controlling the control device of mobile terminal heat radiation or controlling assembly, its concrete shape
Formula can by those skilled in the art according to practical matter depending on, do not limit.
In order to mobile terminal is ensured stable radiating effect, the audio signal that speaker is sent should be believed for single-frequency
Number.Frequency and the volume of simple signal are the most controlled, to produce different grades of radiating effect.In order to reduce audio signal pair as far as possible
The impact of human body, the frequency of simple signal is relatively low, typically can at 100Hz once, and this frequency human ear is difficult to hear, thus is used for
Human body will not be caused sense of discomfort by the audio signal carrying out dispelling the heat.
In the present embodiment, the first duty of speaker in detection mobile terminal, then when speaker is idle condition,
Control speaker and send audio signal, to go out the air flowing of sound intracavity before promoting mobile terminal, and take away by mobile terminal
Heat source component produce and conduct to the heat front going out sound intracavity.Thus utilize speaker to send audio signal, promote movement
Go out air in sound chamber before terminal inner and produce flowing, and heat source component is produced, and conduct to the heat front going out sound intracavity
Take out of inside mobile terminal, play radiating effect for mobile terminal.
In order to effectively dispel the heat according to the heat condition within mobile terminal, need according to the temperature within mobile terminal
Situation is controlled.Fig. 5 is the schematic flow sheet of the another kind of mobile terminal heat dissipating method that the embodiment of the present invention two provides.Such as figure
Shown in 5, before control speaker sends audio signal, also include,
S201, the temperature of detection heat source component；
Concrete, to mobile terminal internal heat resource parts temperature detection, it is possible to use temperature biography mobile terminal within
Sensor is carried out.Wherein, because heat source component typically has multiple, and the thermal change of heat source component self is more violent, thus warm
Degree sensor should be avoided too close to heat source component, such as baseband chip, power management (Power Management is called for short PM)
Chip and radio-frequency power amplifier (Radio Frequency Power Amplifier is called for short RFPA) etc., in order to avoid detect
Temperature is disturbed by the thermal fluctuation that heat source component self is the most violent.
S202, temperature according to heat source component determine frequency and the level of sound volume of audio signal；
Temperature according to heat source component, it may be determined that the febrile state within mobile terminal.Because speaker is sent
When the frequency size of audio signal and volume change, produced sound wave during speaker sounding, it causes air to flow
Effect is different, so, frequency and the level of sound volume of audio signal according to the temperature of detected heat source component, can be determined,
To adjust the radiating effect of mobile terminal.
Wherein, because the frequency of audio signal and level of sound volume go out the air flowing in sound chamber before all affecting mobile terminal
Effect, so when being specifically controlled, can being a rated value by frequency or sound volume setting, and adjust the big of another parameter
Little.Concrete, determine that the frequency of audio signal and the step of level of sound volume include according to the temperature of heat source component:
In frequency one timing of audio signal, close according to the size between temperature and the preset temperature threshold value of heat source component
System, determines the level of sound volume of audio signal；Or level of sound volume one timing in audio signal, according to the temperature of heat source component with
Magnitude relationship between preset temperature threshold value, determines the frequency of audio signal.
With frequency one timing of audio signal, as a example by adjusting level of sound volume, this step is illustrated:
After mobile terminal real-time monitors temperature value by temperature sensor, can according to real-time temperature values T with set in advance
The fixed relation between temperature threshold values judges.Wherein, temperature threshold values can have multiple, such as, can arrange three not
Temperature threshold values T1 (40 DEG C) together, T2 (45 DEG C), T3 (50 DEG C).
Accordingly, the level of sound volume of the audio signal that speaker is exported, namely the output amplitude of audio signal, permissible
It is divided into the different grades such as V1 (without output state), V2 (amplifying 3dB), V3 (amplifying 6dB) and V4 (amplifying 9dB).And speaker
The frequency of exported audio signal, can be divided into Q1 (10Hz), Q2 (25Hz), Q3 (50Hz).
When the frequency of audio signal is certain, such as when unification is set as Q1,
Such as T < T1, then mobile terminal does not export audio signal；
Such as T1 < T, < during T2, the frequency of the audio signal of speaker is 10Hz, and level of sound volume is V2；
As T2 < T, < during T3, the frequency of the audio signal of speaker is still 10Hz, and level of sound volume is V3；
As T > T3 time, the audio signal frequency of speaker is 10Hz, and level of sound volume is V4.
Frequency or the level of sound volume of the sent audio signal of speaker so according to different temperatures, can be set, from
And reach different specific heat loads.
Accordingly, step S102 specifically includes:
S203, when speaker is idle condition, control speaker according to frequency and level of sound volume and send audio signal, with
Promote the air flowing going out sound intracavity before mobile terminal, and take away the heat source component by front going out in sound intracavity mobile terminal and produced
Raw, and conduct to the heat front going out sound intracavity.
Now, can according to determined by the frequency of audio signal and audio grade, control speaker and send audio signal
Dispel the heat.
Thus, the mobile terminal in the present embodiment, can decide whether to utilize speaker to carry out by self duty
Heat radiation, and determine frequency during speaker output audio signal and level of sound volume by the temperature within mobile terminal, to reach
Different specific heat loads, thus utilize speaker to send audio signal and go out the air flowing in sound chamber also before promoting mobile terminal interior
Take away internal heat, reach radiating effect.
