Embodiment
For above-mentioned and other purposes, feature and advantage of the present utility model can be become apparent, cited below particularlyly go out specific embodiment of the utility model, and cooperate appended accompanying drawing, be described in detail below.
Below please refer to the electric charge induction schematic representation of apparatus of Fig. 1 about an embodiment of the present utility model.
In the execution mode of the present utility model, electric charge induction device 10 is applicable to mobile communications device 1, with detect mode that electric charge changes learn whether have object near or away from, for example whether human body near mobile communications device 1.Mobile communications device 1 can be mobile phone, personal digital assistant, and (Personal Digital Assistant, PDA), device such as notebook computer or flat computer, but the utility model is not as limit.And being noted that the utility model does not limit electric charge induction device 10 only can be used for mobile communications device 1, electric charge induction device 10 is also applicable to any device with Anneta module.
Except electric charge induction device 10, also comprise processing module 20, power amplifier 30 and remaining application module (figure does not show) in the mobile communications device 1.Processing module 20 electrically connects with electric charge induction device 10 and power amplifier 30, by software collocation hardware structure or firmware collocation hardware structure forms.Processing module 20 is in order to the effect of all the other application modules in the control mobile communications device 1, converses or transmits function such as data for the user.Because utilizing the function of mobile communications device 1 conversation or transmission data is not the topmost purpose of the utility model, so do not repeat them here the type of action of processing module 20.
Power amplifier 30 is by hardware or firmware collocation hardware structure forms, and electrically connects with antenna 11, in order to receive or to transmit wireless communication signals.Power amplifier 30 can come the power of linear amplification wireless communication signals as required.
Electric charge induction device 10 comprises antenna 11, induction module 12 and the module 13 of damming.Antenna 11 can be a microwave antenna, but the utility model is not as limit.Antenna 11 is in order to the required wireless communication signals of transmission mobile communications device 1, and its wireless communication signals is sent to power amplifier 30 carries out subsequent treatment.Antenna 11 can adjust according to the transmission demand of mobile communications device 1, and the utility model does not limit the specification of antenna 11.
Induction module 12 forms by circuit, chip or firmware collocation hardware mode framework, and the utility model is not as limit.Induction module 12 electrically connects with antenna 11, in order to detect the change in electrical charge signal of antenna 11, with the electric charge of learning that antenna 11 is shown.Since object near or during away from antenna 11, the field pattern of antenna 11 can change simultaneously, the charge generation that further allows antenna 11 show changes.Induction module 12 detects the change in electrical charge signal of antennas 11, comprise the electric charge size that detects antenna 11 with and the voltage difference that changes, with the generation sensing signal to processing module 20.Processing module 20 by sensing signal learn whether have object near or away from mobile communications device 1, and can learn the approximate distance of object and mobile communications device 1, to carry out follow-up processing.
For example, when processing module 20 is learnt the user near mobile communications device 1, processing module 20 can further be controlled the screen (figure does not show) of lighting mobile communications device 1, allows the user can operate mobile communications device 1.Perhaps processing module 20 may command power amplifiers 30 reduce the transmitting power of wireless communication signals, to alleviate the influence of electromagnetic wave to human body.Because the subsequent treatment that processing module 20 is carried out not is a main purpose of the present utility model, so do not repeat them here its control mode.
Yet induction module 12 directly detects the modes of the change in electrical charge signal of antennas 11 and has influence on the required wireless communication signals of antenna 11 transmission mobile communications devices 1 easily, so must have the module 13 of damming between induction module 12, antenna 11 and the power amplifier 30 to block signal interference each other.
And the detailed action principle of the module 13 of damming please refer to Fig. 2, the circuit framework figure of the module of damming that Fig. 2 is had for the electric charge induction device of an embodiment of the present utility model.Being noted that the execution mode of Fig. 2 is to be high-frequency signal with the wireless communication signals, be that example describes and the change in electrical charge signal is a low frequency signal, but signal of the present utility model does not just exceed with the above-mentioned frequency of enumerating.
In an execution mode of the present utility model, the module of damming 13 comprises that radio frequency blocks circuit 131 and direct current blocks circuit 132.Radio frequency blocks circuit 131 and comprises first capacitor C 1 and the inductance L.First capacitor C 1 is electrically connected to each other with inductance L, and first capacitor C 1 is connected to earth terminal again.Inductance L electrically connects antenna 11 and induction module 12 simultaneously.When the wireless communication signals of antenna 11 carry high frequency, inductance L can open circuit to block the transmission of high-frequency signal.And part not by the end of high-frequency signal can be because the characteristic of first capacitor C, 1 high frequency short circuit and direct ground connection.Thus, radio frequency blocks circuit 131 can block high-frequency signal between antenna 11 and the induction module 12, makes wireless communication signals can not be transferred to induction module 12.
Direct current blocks circuit 132 and has 2 direct and antenna 11 and power amplifier 30 electric connections of second capacitor C, 2, the second capacitor C.Therefore the change in electrical charge signal flow of the low frequency of antenna 11 is when second capacitor C 2, and second capacitor C 2 can open circuit to block low frequency signal.Thus, direct current blocks the wireless communication signals that circuit 132 can allow carry high frequency between power amplifier 30 and the antenna 11, but the change in electrical charge signal of low frequency then can't transmit.Therefore by the module 13 of damming, 12 of induction modules can detect the change in electrical charge signal of antenna 11, and can not detect mistake because of the wireless communication signals that receives high frequency, and induction module 12 also can not have influence on the characteristic of antenna 11 simultaneously.
By above-mentioned narration as can be known, by electric charge induction device 10 of the present utility model, mobile communications device 1 can not need additionally to increase an induction antenna just can sense object near or away from mobile communications device 1, and can not have influence on the communication of mobile communications device 1.Therefore mobile communications device 1 of the present utility model can dwindle the space of its internal circuit layout, obviously is better than the mobile communications device of prior art.
To sum up institute is old, and no matter the utility model everywhere all shows it totally different in the feature of known technology with regard to purpose, means and effect, earnestly asks the auditor to perceive, and grants quasi patent early, makes Jiahui society, and the true feeling moral just.Only it should be noted that above-mentioned many embodiment give an example for convenience of explanation, the utility model interest field required for protection should be as the criterion so that the scope of claims is described naturally, but not only limits to the foregoing description.
