Working principle: The hand-cranked alarm is manually rotated by the crank handle, accelerated step by step through the transmission of the gear box, and then drives the beeper to run at high speed through the transmission block. In the process of high-speed operation of the nagwheel, the absorbed air produces high-speed and high-pressure resonance that is simultaneously extruded to the fixed window of the fixed wheel, thereby acting as an alarm.
