Abstract
The utility model relates to an optical-sonic alarming wallet which is composed of a wallet, a magnetic body, a control circuit and a switch. The utility model is characterized in that the utility model can give alarm for the owner via sound and flash when the wallet is stolen to prevent the wallet from being stolen. The utility model has the advantages of simple structure, easy use, low cost and high theftproof performance.
Description
The utility model relates to a kind of antitheft wallet, particularly a kind of antitheft wallet with sound, light warning.
The wallet that present people generally use, because not stolen warning device, when the thief steals, owner is not easy to find, after finding that the thief steals wallet, be not easy also to find where wallet is ensconced by the thief, now in people's the wallet, coin and certificate are increasing, lose wallet and tend to cause very big loss to owner.
The purpose of this utility model is to avoid the shortcoming that exists in the above-mentioned prior art and provides a kind of when wallet is stolen, the antitheft wallet of band sound and light alarm.
The utility model can be realized by following measure:
The utility model is by inclusion, magnet, control circuit, switch is formed, it is characterized in that: control circuit is by magnetic induction switch, the low-frequency pulse oscillating circuit, news are rung oscillating circuit, the flashing current amplifying circuit, sound amplifying circuit, flashing component, the news Chinese percussion instrument, battery constitutes, magnetic induction switch is controlled it by magnet and is opened, close action, the output signal input low-frequency pulse oscillating circuit of magnetic induction switch, the output signal one tunnel of low-frequency pulse oscillating circuit is input to the flashing current amplifying circuit, the driving LED luminous tube, another road is input to news and rings oscillating circuit, and the output signal that news are rung oscillating circuit is input to sound amplifying circuit driving news Chinese percussion instrument.
The utility model will be further described below in conjunction with accompanying drawing (embodiment):
Fig. 1 is a functional-block diagram of the present utility model.
Fig. 2 is an electrical schematic diagram of the present utility model.
Fig. 3 is user mode figure of the present utility model.
With reference to Fig. 1,1 is magnet, and 2 is magnetic induction switch, and 3 is the low-frequency pulse oscillating circuit, and 4 are news sound oscillating circuit, and 5 is sound amplifying circuit, and 6 are the news Chinese percussion instruments, and 7 is the flashing current amplifying circuit, and 8 is the LED luminous tube.
With reference to Fig. 2,9,10,11,12 are respectively not circuit.
With reference to Fig. 3,13 is hand switch, and 14 is circuit board, and 15 is inclusion.
With reference to the circuit of Fig. 2, resistance R
1, capacitor C
1, not circuit 9,10 constitutes the low-frequency pulse oscillating circuits; Resistance R
2, capacitor C
2And not circuit 11,12 constitutes news and rings pulse oscillation circuits, and resistance R is leaded up in the signal output of low-frequency pulse oscillating circuit
3Be transported to the flashing current amplifying circuit, the driving LED luminous tube is luminous, and another road is by diode D
1Be transported to news and ring oscillating circuit, news are rung the interruption news of oscillating circuit output and are rung pulse signal, pass through R
4Be coupled to news and ring amplifying circuit, through BG
2And BG
3After signal amplifies, drive electric and magnetic oscillation and sound.
When magnet 1 during near magnetic switch 2, the level of magnetic switch 2 output terminals A points is 0, not circuit 9,10 and resistance R 1, the output signal Q1 level point of the low-frequency pulse oscillating circuit that capacitor C 1 is formed is 0, and D1 also conducting simultaneously makes the B point also be low level 0, and news are rung the oscillating circuit failure of oscillations, the level of its output Q2 also is 0, amplifier BG1, BG2, BG3 all is in stand-by state by entire circuit.
When magnet 1 leaves magnetic switch 2 certain distances, the output terminals A of magnetic switch 2 is a high level, through the low-frequency pulse oscillating circuit, the low frequency pulse signal of base output Q1 output, one the tunnel is luminous through amplifier BG1 amplification driving LED, and another road is cut through diode D1, and news are rung oscillating circuit work, its output oscillation pulse signal is through amplifier BG2, and BG3 amplifies driving electromagnetism news sound and sends intermittent sound.
The utility model is when practical application, circuit lath 14 will be made after the entire circuit cure package, put into inclusion 15 the insides, surface at inclusion 15, hand switch 13 is installed, when not needing to report to the police, just can achieve the goal by hand switch 13, LED flash tube 8 Homeway.com Chinese percussion instruments 6 are also adorned respectively and are opened in the inclusion, in use, put supporting magnet earlier in the pocket and put wallet again into, and pull out logical switch, control circuit when main in the inclusion is in stand-by state, if the thief steals wallet, wallet leaves the magnet certain distance, and the will light warning device on the wallet flashes and sound at once, inform that the wallet of leting others have a look at is stolen, thereby reach the purpose that prevents that wallet from being taken away by the thief.
When not needing to report to the police, only need hand switch 13 is pulled out the position of closing, wallet just can be used as common wallet and equally uses here.
The utlity model has simple in structurely, easy to use, cost is low, antitheft point.
Claims (3)
1, the antitheft wallet of a kind of sound and light alarm, by inclusion, magnet, control circuit, switch is formed, it is characterized in that: control circuit is by magnetic induction switch, and the low-frequency pulse oscillating circuit is interrogated and rung oscillating circuit, the flashing current amplifying circuit, sound amplifying circuit, flashing component, the news Chinese percussion instrument, battery constitutes, magnetic induction switch is controlled it by magnet and is opened, close action, the output signal input low-frequency pulse oscillating circuit of magnetic induction switch, the output signal of low-frequency pulse oscillating circuit, the one tunnel is input to flashing current amplifying circuit driving LED luminous tube, another road is input to news and rings oscillating circuit, and the output signal that news are rung oscillating circuit is input to sound amplifying circuit driving news Chinese percussion instrument.
