Marine Piston Electric Whistle
Marine piston-type electric whistle utilizes an electric motor as the prime mover. Through gear transmission, the eccentric shaft rotates at high speed, driving the piston to perform rapid reciprocating motion in the piston cylinder. This compresses the air in the sound-producing chamber, producing the whistle sound.
