For example, the first voltage may be 12V, and the second voltage may be 5V.
Fig. 4 is a schematic structural diagram of another vehicle-mounted alarm device according to an embodiment of the present invention, and referring to fig. 4, optionally, the vehicle-mounted alarm device further includes a first resistor R3, a second resistor R4, a third resistor R5, and a sensitivity adjustment switch Q3;

The exemplary control module in this embodiment includes a first control unit 210 and a second control unit 220, and the second terminal of the first resistor R3 is electrically connected to the input terminal A3 of the first control unit 210. When the sensitivity adjusting switch Q3 is turned off, the control signal generated by the sensing module 100 is divided by the first resistor R3 and the fourth resistor R4 and then transmitted to the input terminal A3 of the first control unit 210, and the voltage value input by the input terminal A3 of the first control unit 210 is the voltage value at both ends of the second resistor R4.

When the customer wants to trigger the first and second prompting units L1 and L2 to send out the prompting signals under a larger vibration force, the sensitivity adjusting switch Q3 may be closed. Since the resistance of the equivalent resistor after the second resistor R4 and the third resistor R5 are connected in parallel is 23.5K Ω, the voltage generated by the sensing module 100 is shared by the equivalent resistor and the first resistor R3 in series. At this time, when the sensing output end of the sensing module 100 outputs 1.94V, the first prompting unit L1 and the second prompting unit L2 can be triggered to send out prompting signals.

The fourth resistor R6, the fifth resistor R7 and the sixth resistor R8 are connected in series between the first power source terminal Vdd and the second power source terminal Vss, the voltage value inputted from the adjustment input terminal D1 of the first control unit 210 is the voltage value inputted from both ends of the fifth resistor R7 and the sixth resistor R8, and the voltage inputted to the adjustment input terminal D1 of the first control unit 210 can be changed by adjusting the size of the fifth resistor R7. And the voltage at the adjustment input terminal D1 of the first control unit 210 is proportional to the set threshold, and the magnitude of the set threshold can be adjusted by adjusting the voltage value input at the adjustment input terminal D1 of the first control unit 210. Furthermore, the user can adjust the set threshold value according to the requirement.
