Abstract
The utility model introduces anti-theft alarming card. The alarming card seals an alarm sound integrated circuit board, a buzzer connected with the alarm sound integrated circuit board and a battery in a plastic film flaky bag; the sound control electrodes of the electrode of the integrated circuit board are respectively stuck inside the alarming card and partially overlapped; a position of which the inside is provided with a control electrode in the alarming card is pressed by hands; the alarming card can send out alarm sounds. The utility model is especially suitable for being placed among bank notes in pockets for preventing the bank notes from being stolen. The utility model has the advantages of compactness and practicability.
Description
The utility model is established and a kind of alarm, is a kind of burglar alarm card specifically.
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 the people just not effect of this alarm to not using wallet.
The purpose of this utility model just provides a kind of card form alarm that can report to the police during with the bank note in the hand lined dress bag to the thief.
The technical solution of the utility model is: connect piezo, battery on a surface-mounted integrated circuit that can produce chimes of doom, its sounding control electrode is to make with two sheet metals, all element is encapsulated in the sack of a plastic film, for attractive in appearance, in plastic film, enclose two pictures, be the foregoing circuit element between two pictures, adopt the sealing-in of plastic packaging method to become card form.Described control electrode sheet is bonded at an end of picture inboard with double faced adhesive tape, and some is overlapping for two electrode slices, and parallel, does not contact mutually.
When pinching on the control electrode sheet with hand, two electrode contacts have triggered integrated circuit work, emit the sound signal of certain hour, and piezo is just sent chimes of doom.
Below in conjunction with description of drawings embodiment of the present utility model.
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.
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 a cross-sectional schematic of the present utility model.The said elements that welding is good is contained in the plastic film bag 5, and control electrode 4 usefulness double faced adhesive tapes are bonded at the edge in the plastic film.Some is overlapping for two plate electrodes, but does not contact.Three edge plastic packagings of plastic film 5 together.Another side sticks together with transparent rubberized fabric.
