Referring to Fig. 1, Fig. 1 is the module diagram of terminal device 100 in one embodiment of the application, Fig. 1 illustrates institute
State the subelement of terminal device 100.
As shown in Figure 1, the terminal device 100 includes antenna module 1, controller 2 and state detecting unit 3.It is described
State detecting unit 3 is used to detect the current working condition of the terminal device 100.Wherein, the working condition can be logical
Speech phase, standby mode, communications status etc..The talking state includes but not limited to take phone using dialer software, utilize
Call software take phone, using communications applications software, for example, wechat and QQ etc. carry out voice-enabled chat etc..
Wherein, the antenna module 1 includes antenna 11, radiation direction adjusts unit 12 and RF transceiver 13.
The antenna 11 adjusts unit 12 with the RF transceiver 13 and the radiation direction and is electrically connected, the control
Device 2 processed also adjusts unit 12 with the RF transceiver 13 and the radiation direction and is electrically connected.The radiation direction adjusts single
For member 12 for adjusting the radiation direction of the antenna 11, specific is the radiation direction for the aerial signal for adjusting antenna 11.
The controller 2 is used to detect the current working condition of the terminal device 100 in the state detecting unit 3
During for talking state, the radiation direction is controlled to adjust unit 12, the radiation direction of the antenna 11 is adjusted to the first radiation side
To, and the RF transceiver 13 is controlled to increase the operating power of the antenna 11.
The controller 2 is additionally operable to detect the current work shape of the terminal device 100 in the state detecting unit 3
When state is not talking state, the radiation direction is controlled to adjust unit 12, the radiation direction of the antenna 11 is adjusted to the second spoke
Direction is penetrated, and the RF transceiver 13 is controlled to reduce the operating power of the antenna 11.
In some embodiments, the operating power of the antenna 11 refers to that the RF transceiver 13 emits and receive institute
It states the transmitting of the aerial signal of antenna 11 and receives power.
In some embodiments, it when the working condition of the terminal device 100 is talking state, needs to set the terminal
Standby 100 converse in target object pre-determined distance.Wherein, the target object can be human body, for example, for human ear
Wait human bodies.Wherein, the pre-determined distance can be 10CM (centimetre).
Wherein, first radiation direction is to deviate the direction of the target object, that is, does not radiate the target pair directly
The direction of elephant.Second radiation direction is the best radiation direction of the antenna 11, wherein, when the antenna 11 is in best
During radiation direction, under same operating power, the radiance of the antenna 11 is best.
So as to when the current working condition of the terminal device 100 is talking state, show target object very likely
Close to the terminal device 100, the radiation direction of the antenna 11 is adjusted to the first radiation direction for deviateing target object, from
And avoid directly radiating target object, SAR value is reduced, while improve the operating power of the antenna 11, ensure that communication matter
Amount.Further, when the current working condition of the terminal device 100 is not talking state, show that target object is relatively remote
From the terminal device 100, the radiation direction of the antenna 100 is adjusted to the second radiation direction of best radiation direction, and
And the operating power of the antenna 11 is reduced, it equally ensure that communication quality, also reduce energy consumption.
Please also refer to Fig. 2, the terminal device 100 further includes positive S1, side S2 and back side S3.If first spoke
Direction is penetrated as D1, the first radiation direction D1 concretely deviates predetermined angle with the outside vertical direction x1 of the front S1
The direction of more than θ 1 (such as 60 degree).For example, can be the side S2 (deviateing an angle of 90 degrees) or back side S3 to the terminal device 100
The direction of (deviateing 180 degree angle) radiation.
Also referring to Fig. 3, the terminal device 100 further includes display screen 5, and the front S1 refers to the display screen
Face where 5.The back side S3 of the terminal device 100 refers to the another side opposite with the front S1, the terminal device
100 side S2 refers to connecting the face of the front S1 and back side S3, including four side S2 up and down.
Under normal conditions, user is using the terminal device 100, such as during mobile phone, needs the terminal device 100
The majority of case for placing closer human body is to make a phone call, at this point, being all the positive S1 of the terminal device 100 namely described
5 side of display screen is near or adjacent to human body.It tends to cause SAR (specific absorption rate) value exceeded at this time.
In the application, when the state detecting unit 3 detects the current working condition of the terminal device 100 as call
During state, show positive S1 of the target object close to the terminal device 100, by the radiation direction of the antenna 11 be adjusted to
First radiation direction of side S2 or the back side S3 radiation of the terminal device 100, avoids the 11 face human body of antenna
Radiation, so as to reduce SAR value, meanwhile, the RF transceiver 13 is controlled to increase the operating power of the antenna 11, it can be with
Ensure that the intensity of aerial signal is met the requirements, and ensure that communication quality.
When it is not talking state that the state detecting unit 3, which detects the current working condition of the terminal device 100,
Show that the radiation direction of the antenna 11 without the positive S1 close to the terminal device 100, is adjusted to antenna by target object
Second radiation direction of 11 best radiation direction, due to the radiation direction of the antenna 11 it is best when, same power will
There is best communication quality, so as at this point it is possible to reduce the operating power of the antenna 11, reduce power consumption.
Obviously, in some embodiments, the talking state and first radiation direction can also be according to other demands
It is configured.For example, the talking state is talking state of the terminal device 100 under non-hands-free state；It is or, described logical
Speech phase is call of the terminal device 100 in the case where non-hands-free state and the terminal device 100 do not access earphone
State.First radiation direction can also be inclined with the outside vertical direction of the side S2 of the bottom end F1 of the terminal device 100
Direction from more than the 1 predetermined angle θ.Since the bottom end F1 of terminal device 100 is usually provided with the components such as receiver, from
And the effect for reducing SAR value can be also played when being used for user close to the receiver call of bottom end F1.
In further embodiments, first radiation direction is meets the positive S1 with the terminal device 100 simultaneously
Outside vertical direction x1 deviate the direction more than predetermined angle θ 1 (such as 60 degree) and the bottom end with the terminal device 100
The outside vertical direction of side S2 deviate the direction of more than the 1 predetermined angle θ.
So as to which first radiation direction can be to deviate in advance with the positive outside vertical direction of the terminal device 100
If more than angle direction and/or deviateing with the outside vertical direction of the side of the bottom end of the terminal device 100 described default
Direction more than angle.
