Provided is an alarm device preventing a storage battery of a vehicle from being stolen. The alarm device comprises an electric circuit part and an air circuit part. The electric circuit part comprises the storage battery and a normally open solenoid valve. The positive electrode end of the storage battery is connected with one end of a horn button, the other end of the horn button is connected with the positive electrode end of the normally open solenoid valve, and the negative electrode end of the normally open solenoid valve is connected with the negative electrode end of the storage battery. The air circuit part comprises an air reservoir and an air horn. The air reservoir is communicated with an air inlet of the normally open solenoid valve, and an air outlet of the normally open solenoid valve is communicated with the air horn. The alarm device further comprises a normally closed solenoid valve. The positive electrode end of the normally closed solenoid valve is connected with the positive electrode end of the storage battery, and the negative electrode end of the normally closed solenoid valve is connected with the negative electrode end of the storage battery; an air inlet of the normally closed solenoid valve is communicated with the air reservoir, and an air outlet of the normally closed solenoid valve is communicated with the air horn. The alarm device not only is good in anti-theft effect but also does not affect normal operation of the vehicle.
