An automatic ice maker for saving an ice making time. The automatic ice maker has a U-shaped resonator filled up with an inertia gas, a pair of ice trays attached to both ends of the U-shaped resonator in a reverse direction to each other, a pair of speakers attached to both ends of the U-shaped resonator for compressing and expanding parcels of the inertia gas by applying an acoustic pressure to the U-shaped resonator thereby varying a temperature distribution in the U-shaped resonator, a pair of heat exchangers for transferring an inner temperature of the U-shaped resonator to the ice trays, a reversible motor for driving the U-shaped resonator in a forward or a reverse direction at an angle of 180 degrees, and an electric control unit for sequentially operating the speakers and the reversible motor. The automatic ice maker can be adopted to a refrigerator or other refrigeration system. By the automatic ice maker, the ice making time can be saved and the productivity in making the ice increases.
