Problems solved by technology

There are anti-theft devices that use wireless transmitting and receiving pendants. When the mobile phone exceeds the set distance, it will alarm, but it also brings great inconvenience when using it. The specific transmission and reception codes are very limited, which is not suitable for large-scale promotion. Once it is widely promoted, it is easy to cause interference; there are also mobile phone anti-theft cases, which will alarm when the mobile phone is taken out of the mobile phone case, but this design is very "bad" , It is extremely inconvenient to use; there is also a technology for mobile phone anti-theft tracking cards, which can send information to users after the mobile phone is stolen and the SIM card is replaced, but it needs to

Embodiment Construction

[0022] Below in conjunction with accompanying drawing, the embodiment of the present invention is described in further detail:

[0023] figure 1 The present invention shown includes a mobile phone body, a battery, a light control switch, a magnetic control switch, and an alarm circuit. The light control switch is connected to the alarm circuit, and the alarm circuit is connected to the magnetic control switch.

[0024] The light control switch is mainly composed of a photoresistor, a photodiode, a phototransistor, a combined circuit of a photodiode, a resistor, a triode, and a photosensitive sensor. There are many combinations possible:

[0025] 1. If figure 2 As shown, the photoresistor can be connected with the voltage comparator to set the changing range of the light. When the light intensity is within the set intensity, the comparator outputs a low level to maintain the current state of the circuit; when the light exceeds this range, the comparator outputs a high level...

Abstract

The invention relates to a light-operated pure hardware circuit anti-theft mobile phone, which comprises a mobile phone body, a battery, a light-operated switch, a magnetic control switch and an alarm circuit, wherein the light-operated switch is connected with the alarm circuit, and the alarm circuit is connected with the magnetic control switch. The invention can find that the mobile phone is taken away from the body as soon as possible, adopts light control technology and works stably, a password authentication function protects the alarm function of the mobile phone against easy shutoff, and the magnetic control switch is used to protect the battery against disassembly and ensures that the alarm function can not be shut off.

Description

technical field [0001] The invention relates to a mobile phone, more specifically, to a light-controlled pure hardware circuit anti-theft mobile phone. Background technique [0002] The role of mobile phones in life is becoming more and more important, and it has entered all walks of life and has become a must-have for life and work. Mobile phones bring people a lot of convenience and fun, but they have opened up a shortcut to "profit" for some lawbreakers. Because mobile phones are small and exquisite, easy to carry, and expensive, they are favored by thieves. Although some anti-theft methods have also been done for mobile phones on the market, most of them are unsatisfactory. There are anti-theft devices that use wireless transmitting and receiving pendants. When the mobile phone exceeds the set distance, it will alarm, but it also brings great inconvenience when using it. The specific transmission and reception codes are very limited, which is not suitable for large-sc...
