Embodiment:
Also the present invention is described in further detail in conjunction with the accompanying drawings below by specific embodiment.
Embodiment one: as Fig. 2 and shown in Figure 5, a kind of battery mouse of exempting from comprises the signal generating circuit 11, power supply processing circuit 12, modulation circuit 13 and the inductive coil that are used for the sensitive mouse displacement, and described inductive coil is an induced emission coil 14; The output terminal of induced emission coil 14 is connected to the input end of power supply processing circuit 12.Signal generating circuit is connected to induced emission coil 14 through modulation circuit 13.
In the foregoing circuit, also can adopt special sender unit, signal generating circuit is connected to sender unit through modulation circuit 13, and signal is sent.
As shown in Figure 1 and Figure 4, a kind of battery mouse/keyboard receiver of exempting from, in order to constitute the signal transmission between mouse 10 and host A, it comprises that microprocessor 21, ac signal circuit 22, driving circuit 23, emission receiving coil 24 and signal amplify demodulator circuit 25 and signal processing circuit 26; The input end of exempting from the signal wire 27 of battery mouse/keyboard receiver 20 directly is connected with host computer A, the power supply signal output terminal of microprocessor 21 or the power lead of host computer are connected to the input end of ac signal circuit 22, the input end of ac signal circuit 22, the output terminal of ac signal circuit 22 are connected to the emission input end of emission receiving coil 24 through driving circuit 23.The reception output terminal of emission receiving coil 24 is connected to microprocessor 21 through signal amplification demodulator circuit 25 and signal processing circuit 26.
With exempt from that the battery mouse is corresponding to be, exempt from battery mouse/keyboard receiver and also can adopt special signal receiving device, the reception output terminal of signal receiving device amplifies demodulator circuit 25 and signal processing circuit 26 is connected to microprocessor 21 through signal.
