Embodiment Construction

[0009] exist figure 1 Among them, the mobile phone anti-theft device is mainly composed of an infrared transmitter (5) and an anti-theft device. The anti-theft device includes a battery (3), a speaker (2), a program processing chip (4) and an infrared receiver (1), and is installed in the mobile phone. . When we need to prevent the mobile phone from being lost, as long as the power switch (6) on the infrared transmitter (5) is pressed, the infrared receiver (1) is powered on, and then the signal transmission switch (7) is pressed, and the chip is processed by the program ( 4) processing, once the signal cannot be received due to exceeding the set distance, the circuit in the anti-theft device will be connected, so that the battery (3) will supply power to the horn (2), and an alarm will sound. This also reminds the user, thereby playing a very good anti-theft effect.

Abstract

The present invention relates to a mobile phone antitheft device which is mainly composed of an infrared transmitter and an antitheft machine, wherein the antitheft machine comprises a cell, a horn, a program processing chip and an infrared receiver, and is placed in a mobile phone. When the mobile phone needs to be prevented to lose, only a powering switch on the infrared transmitter needs to be pressed down; the infrared receiver is used for powering on the electricity, and then, a signal transmitting switch is pressed down; the program processing chip is used for processing; once transmitted signals are not received because the set distance is overstepped, then, circuits in the antitheft machine are communicated, and thus, the cell supplies electricity to the horn to send out alarming sound. Thereof, a user is reminded, so the mobile phone antitheft device has good antitheft function.
