The beneficial effects of the utility model are:
The utility model is a kind of light control alarm formula luggage case burglar alarm, compared with prior art, the utility model adopts photodiode to be alarm trigger, when there being people illegally to open luggage case, sense extraneous light and send chimes of doom warning, thus effectively play alarm function, and easy to use, there is the value applied.
Accompanying drawing explanation
Fig. 1 is circuit structure schematic diagram of the present utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail:
As shown in Figure 1: the utility model comprises battery GB, first triode VT1 is to the 3rd triode VT3, potentiometer RP, switch S Q, the integrated chip IC of sound, photodiode LD, resistance R and loudspeaker B, the positive pole of battery GB is connected with the first end of switch S Q, the negative pole of battery GB simultaneously with the first end of loudspeaker B, the emitter stage of the second triode VT2, the negative pole of the integrated chip IC of sound, the negative pole of photodiode LD connects, second end of switch S Q simultaneously with the emitter stage of the 3rd triode VT2, the positive pole of the integrated chip IC of sound, the colelctor electrode of the first triode VT1, the first end of potentiometer RP is connected with sliding end, second end of potentiometer RP is connected with the positive pole of photodiode LD and the base stage of the first triode VT1 simultaneously, the emitter stage of the first triode VT1 is connected with the input of the integrated chip IC of sound, the two ends of resistance R connect the reset terminal of the integrated chip IC of sound respectively and reset end, the output of the integrated chip IC of sound is connected with the base stage of the second triode VT2, the colelctor electrode of the second triode VT2 is connected with the base stage of the 3rd triode VT3, and the colelctor electrode of the 3rd triode VT3 is connected with second end of loudspeaker B.
Operation principle of the present utility model is as follows:
During utility model works, under bed of cloth switch S Q being hidden in luggage case or cortical layer, switch S Q is opened time user leaves, when there being people illegally to open luggage case, photodiode LD senses extraneous light, thus make the first triode VT1 conducting and toggle sound integrated chip IC output audio, make loudspeaker B send chimes of doom.
Component parameter of the present utility model is selected as follows:
Battery GB is 3V, the first triode VT1 and the second triode VT2 is NPN type triode, and the 3rd triode VT3 is PNP type triode, potentiometer RP is 500 Ω, the model of the integrated chip IC of sound is KD9561, resistance R is 2k Ω.
More than show and describe general principle of the present utility model and principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; what describe in above-described embodiment and description just illustrates principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
