The invention discloses a vehicle-mounted alarm device and a vehicle thereof. The vehicle-mounted alarm device comprises an alarm device body; the alarm body comprises a power supply unit, an MCU chip unit, a field effect transistor H-bridge circuit and a loudspeaker. The power supply unit is connected with a vehicle control device through a wire; the MCU chip unit is used for outputting two paths of direct-current square-wave high-low level signals to the field-effect tube H-bridge circuit; and the field-effect tube H-bridge circuit is connected with the loudspeaker, converts the two paths of direct-current square-wave high-low level signals into alternating-current square-wave signals and sends the alternating-current square-wave signals to the loudspeaker, so that the loudspeaker gives an alarm. The vehicle-mounted alarm can work stably for a long time in various environments, the service life is long, the alarm effect is good, the cost is low, and the good working state of the vehicle-mounted alarm is effectively guaranteed.

    本发明公开了一种车载报警器及其车辆,其中的车载报警器包括:报警器本体;报警器本体包括:电源单元、MCU芯片单元、场效应管H桥电路和扬声器;电源单元通过导线与车辆的控制装置连接;MCU芯片单元用于向场效应管H桥电路输出两路直流方波高低电平信号;场效应管H桥电路与扬声器连接,将两路直流方波高低电平信号转换为交流方波信号发送给扬声器,以使扬声器发出警报。本发明能够保证车载报警器在多种环境中长时间稳定工作,使用寿命长,报警效果好,成本低,有效保证车载报警器的良好工作状态。
