Compared with prior art, the beneficial effects of the utility model are: the utility model alarm appicance for wallet can release chimes of doom when thief touches wallet edge electric pole piece, warns to people, frighten thief away simultaneously, circuit structure is simple, is applicable to various wallet, is applicable to very much promoting the use of.
Accompanying drawing explanation
Fig. 1 is the circuit diagram of alarm appicance for wallet.
Detailed description of the invention
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Refer to Fig. 1, in the utility model embodiment, a kind of alarm appicance for wallet, comprise resistance R1, key switch S, triode VT1, electrode slice, electric capacity C1 and buzzer B, resistance R1 one end is connected with multiple electrode slice, the resistance R1 other end is connecting triode VT1 colelctor electrode respectively, key switch S and triode VT2 base stage, triode VT1 emitter stage connects power supply VCC, triode VT1 base stage connecting triode VT2 colelctor electrode, triode VT2 emitter stage connects electric capacity C1 respectively, resistance R2 and triode VT4 emitter stage, the resistance R2 other end connects electric capacity C2 respectively, electric capacity C3 and triode VT3 base stage, triode VT3 colelctor electrode connecting triode VT4 base stage, triode VT4 colelctor electrode is contact resistance R3 and buzzer B respectively, the resistance R3 other end connects the electric capacity C2 other end, the described buzzer B other end connects the electric capacity C3 other end respectively, triode VT3 emitter stage, the electric capacity C1 other end and the key switch S other end.
Power supply VCC voltage is 6V.
Power supply VCC adopts button cell to power.
Key switch S is located at wallet inside.
Multiple electrode slice is positioned at four end points edges on the square two sides of wallet.
Operation principle of the present utility model is: refer to Fig. 1, triode VT1 and VT2 etc. form analog switching circuit, two pipes are in cut-off state at ordinary times, when there being people to touch electrode slice, two pipe just rapid conductings, triode VT3 and VT4 etc. form complimentary audio oscillator, when VT1 and VT2 pipe ends, the blocking of oscillator, VT1 and VT2 pipe is once conducting, oscillator is starting of oscillation immediately, buzzer B sends continual chimes of doom at once, and key switch S is alarm release switch, after S presses, triode VT1 and VT2 ends, and oscillator also stops oscillation.
To those skilled in the art, obvious the utility model is not limited to the details of above-mentioned one exemplary embodiment, and when not deviating from spirit of the present utility model or essential characteristic, can realize the utility model in other specific forms.Therefore, no matter from which point, all should embodiment be regarded as exemplary, and be nonrestrictive, scope of the present utility model is limited by claims instead of above-mentioned explanation, and all changes be therefore intended in the implication of the equivalency by dropping on claim and scope are included in the utility model.Any Reference numeral in claim should be considered as the claim involved by limiting.
In addition, be to be understood that, although this description is described according to embodiment, but not each embodiment only comprises an independently technical scheme, this narrating mode of description is only for clarity sake, those skilled in the art should by description integrally, and the technical scheme in each embodiment also through appropriately combined, can form other embodiments that it will be appreciated by those skilled in the art that.
