The power supply voltage is input to a speech generator Ic1 through an overvoltage protection circuit, the wave filtering and the voltage stabilization; the open and close of a delay relay [J] is controlled by a steering square wave signal through a gate circuit and a transistor. A speech signal output by the speech generator Ic1 is amplified through a pre-amplifier and a main power amplifier Ic2, and a speech alarm signal is sent out by a loudspeaker. The overvoltage protection circuit is formed by connecting voltage stabilizing tubes WD1 and WD2 and resistors R15 and R16 with the base of a transistor BG1. A filter circuit is composed of an electronic filter that is composed of a transistor BG3, a resistor R5 and capacitors C2-C4. The alarm has high anti-interference capability and high anti-overvoltage performance, and the alarm can be universally used in vehicles with voltages of 12V and 24 V.
