When the first shell is opened and the Hall switch cannot detect the magnet, the Hall switch can output another signal to the shell detaching alarm circuit, and the shell detaching alarm circuit gives an alarm under the driving of the other signal. In other embodiments, other detectors, such as infrared or light sensitive, may be used.

In some embodiments of the present invention, the second casing detaching detector may employ a magnetic detector, such as a hall switch, to detect the closed state of the second casing. Two small magnets are arranged at the corresponding positions of the second shell and the Hall switch, and when the Hall switch detects the magnets, corresponding signals can be output to the shell disassembling alarm circuit, so that the shell disassembling alarm circuit cannot give an alarm.

In contrast, when the first cover 20 is opened, the first hall detector or the first microswitch U68(40) outputs a high level, and the high level signal can drive the buzzer J5 to sound an alarm. Therefore, the shell disassembling alarm for the first shell can be realized.
One end of the first capacitor C63 is connected with a signal output end of the first hall detector or the first microswitch U68(40), and the other end of the first capacitor C63 is connected with a reference ground. The signal output by the first hall detector or the first microswitch U68(40) can be filtered through the first capacitor C63, so as to avoid the generation of false alarm due to the interference signal.
The second decapping detector includes: a second switching circuit, the second switching circuit comprising: a second hall detector or a second microswitch U69(50), a second resistor R5151 and a second capacitor C4994, wherein one end of the second resistor R5151 is connected with a power supply + PS _3VSB, the other end of the second resistor R5151 is connected with a signal output end of the second hall detector or the second microswitch U69(50), and the signal output end of the second hall detector or the second microswitch U69(50) is further connected with the shell-disassembling alarm circuit; when the second housing cover 30 is in a closed state, the second hall detector or the second micro switch U69(50) detects the magnet on the second housing cover 30, the pin 2 of the second hall detector or the second micro switch U69(50) is pulled down, and the second hall detection signal output by the second hall detector or the second micro switch U69(50) is output to the buzzer J5, so that the buzzer does not make a sound. Conversely, when the second cover 30 is opened, the second hall detector or the second microswitch U69(50) outputs a high level, and the high level signal can drive the buzzer J5 to sound an alarm. Therefore, the shell disassembly alarm of the second shell can be realized.
One end of the second capacitor C4994 is connected to the signal output end of the second hall detector or second microswitch U69(50), and the other end of the second capacitor C4994 is connected to the reference ground. The signal output by the second hall detector or the second microswitch U69(50) can be filtered by the second capacitor C4994, so as to avoid the generation of false alarm due to the interference signal.

The buzzer driving circuit includes: the source of the first MOS transistor Q7 is connected with a power supply through a third resistor R5152, the source of the first MOS transistor Q7 is further connected with the gate of the first MOS transistor Q7 through a fourth resistor R241 and a fifth resistor R240, the drain of the first MOS transistor Q7 is connected with the buzzer, and the gate of the first MOS transistor Q7 is further connected with the signal output end of the first hall detector or the first microswitch 40, the second hall detector or the second microswitch 50 through the fifth resistor R240. The output signal of the first hall detector or the first microswitch 40, the second hall detector or the second microswitch 50 can be amplified and output through the first MOS transistor Q7. This allows a larger drive current to be passed to the buzzer J5. So that the buzzer makes a larger alarm sound.
The buzzer driving circuit further comprises a transistor driving circuit, and the grid electrode of the first MOS transistor Q7 is connected with the signal output end of the first hall detector or the first microswitch 40, the second hall detector or the second microswitch 50 through the fifth resistor R240 and the transistor driving circuit; wherein the transistor driving circuit includes: a second MOS transistor Q88, wherein the source of the second MOS transistor Q88 is connected to ground, the drain of the second MOS transistor Q88 is connected to the gate of the first MOS transistor Q7 through the fifth resistor R240, and the gate of the second MOS transistor Q88 is connected to the signal output terminal of the first hall detector or the first microswitch 40, the second hall detector or the second microswitch 50 through the sixth resistor R243.

The working process is specifically that when the first hall detector or the first microswitch U68(40) and the second hall detector or the second microswitch U69(50) detect the magnets, the first shell and the second shell are both in a closed state. At this time, the signal output end HALL _ DET1 of the first HALL detector or the first microswitch U68(40) and the second HALL detector or the second microswitch U69(50) all output a low level, the pin Q88S, D of the N second MOS transistor is not conducted, so that the pin D is a high level, the pin Q72-3 of the P first MOS transistor is not conducted, and the buzzer of the J5 is not powered.
