As it is a hand-cranked siren, the primary speed of the hand-cranked siren determines the sound effect of the siren. Rotation speed is directly proportional to sound effect. Relatively speaking, the higher the speed, the louder the sound. There is a difference between people shaking the alarm. People's height, strength, shaking speed, etc. are all direct factors that affect the sound effect of the siren, so we have made a macro regulation here, the primary speed of shaking cannot be less than 90r/min, otherwise it will not reach the expected sound effect.
