Description
Technical field
The utility model relates to electricity field, particularly a kind of anti-stealing device for handset.
Background technology
Mobile phone has become important aid and the instrument of people's work, life.In mobile phone, do not only have address list, the important personal information such as communication record, also may have some significant datas, file.Because important communication function, memory function and the data processing function of mobile phone, once forget or lose and may bring very large loss.In prior art, have some anti-stealing device for handset, but these anti-stealing device for handset itself also easily lose, be the problem that those skilled in the art need to solve so a kind of reliable anti-stealing device for handset is provided.
Utility model content
The problem that the utility model solves is in prior art, to lack a kind of anti-stealing device for handset reliably; For solving described problem, the utility model provides a kind of anti-stealing device for handset.
Anti-stealing device for handset provided by the utility model, comprising: master chip and secondary chip; When the distance of described master chip and secondary chip is greater than setting value, described master chip sounds the alarm.
Further, described master chip comprises power supply, signal receiving module, signal comparison module and sounding module; Described secondary chip comprises signal generator module and power supply.
Further, when work, described signal generator module emitting radio frequency signal; Described signal receiving module receives after described radiofrequency signal, be transferred to described signal comparison module, preset signals in the more described radiofrequency signal of described signal comparison module and master chip, in the time that the intensity of described radiofrequency signal is less than described preset signals, described sounding module sounds the alarm.
Further, described master chip also comprises shift knob, volume adjustment knob.
Further, described secondary chip attach is on hand set machine shell, and described master chip is arranged in wrister, and described shift knob and volume adjustment knob stretch out by the opening of wrister side.
Further, described master chip also comprises display module, and described display module calculates the distance between master chip and secondary chip according to the intensity of the radiofrequency signal receiving, and result of calculation is presented on display screen.
Further, described power supply is button cell or solar cell; Described signal receiving module comprises receiving antenna and signal amplifier; Described signal comparison module is comparer; Described sounding module is loudspeaker; Described signal generator module is lc circuit.
Advantage of the present utility model comprises: by master chip and people binding, in the time that the distance between master chip and secondary chip is greater than preset value, master chip sends chimes of doom, thus remind mobile phone everyone.
Further, in the utility model, master chip is arranged in wrister, safe, convenient, comfortable; And shift knob, volume adjustment knob are installed on outdoor outside, be convenient to regulate.
Brief description of the drawings
Fig. 1 is the circuit diagram of the master chip of anti-stealing device for handset provided by the utility model;
Fig. 2 is the circuit diagram of the secondary chip of anti-stealing device for handset provided by the utility model;

Embodiment
Hereinafter, in conjunction with the accompanying drawings and embodiments the utility model is further elaborated.
Anti-stealing device for handset provided by the utility model comprises master chip and secondary chip; When the distance of described master chip and secondary chip is greater than setting value, described master chip sounds the alarm.
Described master chip comprises power supply, signal receiving module, signal comparison module and sounding module; Described secondary chip comprises signal generator module and power supply.As shown in Figure 1, in embodiment of the present utility model, described power supply is battery, such as button cell or solar cell; Described signal receiving module comprises receiving antenna W2, signal amplifier G and rheostat R2, described signal comparison module is comparer D2, the first via of described comparer D2 is input as the preset signals of master chip, intensity regulates by the resistance of rheostat R2, the second tunnel is input as that receiving antenna W2 receives, and amplifies signal after treatment through amplifier G.In the case of the resistance of rheostat R2 is definite, the value of first via input determines, the distance of the first chip and the second chip is larger, and the value of the second tunnel input is less, in the time that the difference of two-way input reaches preset value, and sounding module sound.In the present embodiment, described sounding module is loudspeaker S.For regulating voice signal, can in circuit, access triode P and resistance R 1, resistance R 3.
As shown in Figure 2, described secondary chip comprises power supply, emitting antenna W1 and inductance L, capacitor C.
When work, the signal generator module emitting radio frequency signal that emitting antenna W1 and inductance L, capacitor C form; Described signal receiving module receives after described radiofrequency signal.
In order to prevent to lose because of master chip and secondary chip simultaneously, and lose the anti-theft feature of device provided by the utility model, as shown in Figure 3, in an example of the present utility model, described master chip is installed on wrister 21, and secondary chip 12 is pasted on hand set machine shell 11.
Continue with reference to figure 3, described master chip also comprises shift knob 24, volume adjustment knob 25, and described shift knob 24 and volume adjustment knob 25 stretch out by the opening of wrister 21 sides.
Preferably, described master chip also comprises display module 22, and described display module 22 calculates the distance between master chip 11 and secondary chip 21 according to the intensity of the radiofrequency signal receiving, and result of calculation is presented on display screen 22.
In other examples of the present utility model, described master chip can also be installed on other jewelrys of carrying such as bracelet, school bag shoulder belt.
Although the utility model with preferred embodiment openly as above; but it is not for limiting the utility model; any those skilled in the art are not departing from spirit and scope of the present utility model; can utilize method and the technology contents of above-mentioned announcement to make possible variation and amendment to technical solutions of the utility model; therefore; every content that does not depart from technical solutions of the utility model; any simple modification, equivalent variations and the modification above embodiment done according to technical spirit of the present utility model, all belong to the protection domain of technical solutions of the utility model.
