Description
Technical field
The utility model relates to a kind of anti-stealing device for handset.
Background technology
Fast development along with mechanics of communication, mobile phone has become indispensable communication tool in people's daily life, but mobile phone also is the target that the thief aims at, stolen easily, though people have also taked some as Antistealing measures such as mobile phone chain, cell-phone covers to mobile phone, but in the intensive place of personnel, as on bus and crowded public place, mobile phone still is easy to stolen.
The utility model content
The purpose of this utility model provide a kind of convenient and practical, theftproof performance good, have ornamental anti-stealing device for handset simultaneously.
The utility model is realized above-mentioned purpose by the following technical solutions: a kind of anti-stealing device for handset, comprise the handset shell, the magnetic control anti-theft device that have magnetic part, wherein the magnetic control anti-theft device comprises control chip, control chip is connected with respectively and triggers controlling organization, alarm mechanism, magnetic control trigger mechanism, and wherein the magnetic control trigger mechanism is adsorbed on the magnetic part of handset shell.
The touch pad housing that described triggering controlling organization is a hollow, wherein control chip, alarm mechanism are positioned at the touch pad housing, and the magnetic control trigger mechanism is connected with control chip by connecting line.
The touch pad housing of hollow is the conductive shell that electric conducting material is made.
Described alarm mechanism is a warning circuit, is serially connected with alarm on the warning circuit.
Alarm is loudspeaker.
Described magnetic control trigger mechanism comprises the trigger switch that cooperates with magnetic part, and switch disconnects switch closure when breaking away from magnetic part when trigger switch and magnetic part absorption.
When the magnetic part absorption in the utility model on trigger switch and the handset shell sticks together, trigger switch disconnects, whole system begins standby, when mobile phone is stolen, trigger switch comes off from magnetic part, the trigger switch closure, control chip is connected high voltage, makes loudspeaker work, sends alarm sound, when oneself uses mobile phone, earlier touch the touch pad housing with hand, the touch pad housing sends signal to control chip, and the control chip control circuit is in low-voltage state, loud speaker is not worked, and does not send alarm sound.The utility model cost is low, and is in light weight, easy to carry; Report to the police the most rapidly with simple device realization response; Occupation mode is convenient, understandable; The utility model can be made touch pad different shapes, gives certain ornamentally, and more fashion is easy to be accepted by market.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the utility model circuit block diagram.
Embodiment
As shown in Figure 1, a kind of anti-stealing device for handset, comprise the handset shell 6, the magnetic control anti-theft device that have magnetic part 5, wherein the magnetic control anti-theft device comprises control chip 2, control chip 2 is connected with respectively and triggers controlling organization, alarm mechanism, magnetic control trigger mechanism, wherein the magnetic control trigger mechanism is adsorbed on the magnetic part 5 of handset shell 6, the touch pad housing 1 that described triggering controlling organization is a hollow, the conductive shell that the touch pad housing 1 of hollow is made for electric conducting material; Control chip 2, alarm mechanism is positioned at touch pad housing 1, alarm mechanism is a warning circuit, in circuit, be serially connected with alarm 3, alarm 3 is loudspeaker, emit the bellmouth orifice 8 of alarm sound corresponding setting with loudspeaker from touch pad housing 1, described magnetic control trigger mechanism comprises the trigger switch 4 that cooperates with magnetic part 5, trigger switch 4 is connected with control chip 2 by connecting line 7, trigger switch 4 cooperates the formation magnetic control to trigger with handset shell magnetic part 5, trigger switch 4 disconnected when trigger switch 4 adsorbed with magnetic part 5, switch 4 closures when breaking away from magnetic part 5, trigger switch 4 is made up of conducting film and elastic steel sheet, trigger switch 4 is a prior art, is not described in detail in this.
As shown in Figure 2, touch pad housing 1 connects a pin and the b pin of control chip respectively, the positive pole of power supply, negative pole respectively with the c pin of control chip 2, the f pin connects, trigger switch 4 conducting films are connected the e pin of control chip, elastic steel sheet one end of trigger switch 4 connects the negative pole of power supply, other end elasticity is pressed on trigger switch 4 conducting films, when the elastic steel sheet of trigger switch 4 was adsorbed on the magnetic part 5, elastic steel sheet was adsorbed by magnetic part, leaves conducting film, trigger switch 4 disconnects, when breaking away from magnetic part 5, elastic steel sheet is pressed on the conducting film, trigger switch 4 closures, loudspeaker one end is connected the d pin of control chip 2, other end ground connection.
The course of work: when the magnetic part 5 of trigger switch 4 and mobile phone shell sticks together, trigger switch 4 disconnects, whole system begins standby, when mobile phone is stolen, trigger switch 4 comes off from magnetic part 5, trigger switch 4 closures, IC control d pin is connected high voltage, makes loudspeaker work, when oneself uses mobile phone, earlier touch touch pad housing 1 with hand, touch pad housing 1 sends signal to control chip 2, and IC will control the d pin and be in low-voltage state all the time, then trigger switch 4 is taken off, at this moment trigger switch 4 closures, IC control d pin still is in low-voltage state, and IC is in reset mode, when next trigger switch 4 is attached to magnetic part 5, trigger switch 4 disconnects, and resetting finishes, and whole system begins standby again.
