Abstract
The utility model discloses a theft-proof alarm card and consists of an integrated circuit wafer and a buzzer and batteries that are connected with the integrated circuit wafer. The utility model is connected with the integrated circuit wafer by a pair of metal pieces as the control electrode, the above components are provided within one card, the edge of the card, where the buzzer is places is provided with an sound hole, two control electrodes are stuck in the card with part of the two overlapped without contact. The utility model is used for being clamped in paper money, when the thieve grasp the paper money, the two control electrodes contact to trigger the work of the integrated circuit and to send audio signals within certain time and the buzzer will send out sound alarm.
Description
Technical field
The utility model relates to a kind of burglar alarm card.
Background technology
A kind of burglar alarm that is contained on the wallet is arranged now, and after wallet was stolen, the alarm in the wallet sent chimes of doom.But this alarm complex structure, and invest on the wallet, to the just not effect of people of not using wallet.
Summary of the invention
The purpose of this utility model just provides a kind of burglar alarm card that can report to the police during with the bank note in the hand lined dress bag to the thief.
For achieving the above object, the utility model is taked following technical scheme: comprise surface-mounted integrated circuit and the piezo, the battery that are attached thereto, be wired to respectively on the surface-mounted integrated circuit as control electrode by the pair of metal sheet, above-mentioned whole element is put into a card, there is place's louver the position of placing the beep sheet at the edge of card, two control electrode sheets are bonded in the card, and some is overlapping between the two, but does not contact.
Described card is to be sealed by two picture plastic films, and the pocket type card of an end opening is arranged.
Described surface-mounted integrated circuit be can output audio voltage the special IC plate.
Described battery is put into a battery bag, and its both positive and negative polarity uses wire bonds on the surface-mounted integrated circuit corresponding welding spots.
Described control electrode sheet by elasticity preferably copper sheet make.
Described pair of control electrode is parallel to each other, and has one deck insulating trip to be combined with each other between the one end, and one of them electrode is bonded in described card inboard.
Described two control electrodes are bonded in card two opposed inside respectively.
The utility model is clipped in the bank note, when people's theft is pinched money with hand, two control electrodes is in contact with one another, and triggers integrated circuit work, sends the sound signal of certain hour, drives piezo and sends chimes of doom.
Below in conjunction with description of drawings embodiment of the present utility model.
Description of drawings
Fig. 1 is a used surface-mounted integrated circuit connection layout of the present utility model;
Fig. 2 is a cross-sectional schematic of the present utility model.
Embodiment
Figure 1 illustrates the connection diagram of the utility model circuit component.Audio frequency generation surface-mounted integrated circuit 1 is a universal circuit common on the market, is connected with two copper sheets as control electrode 4 at its trigger end, and battery 3 is slim button cells, and piezo 2 is piezoelectric ceramic pieces.
Fig. 2 is the utility model cross-sectional schematic.The said elements that welding is good is packed in the plastic film bag 5, sticks together with double faced adhesive tape between the end of two control electrodes 4, the outside of an electrode 4 is bonded at the inboard of plastic film bag 5 again.Two plate electrodes do not have an end of double faced adhesive tape to be parallel to each other, but do not contact.Also two electrodes 4 can be bonded at the relative both sides inner face of plastic film bag 5 respectively.Three edge plastic packagings of plastic film 5 together.Another side sticks together with transparent rubberized fabric.
