The present invention relates to a cold brew coffee extraction device that adjusts sound wave vibration based on an acoustic signal equipped with a dual magnet, and more particularly, by improving the structure for applying the sound wave vibration delivered to a container containing an aqueous coffee solution to the sound wave. It relates to a cold brew coffee extraction device that adjusts sound wave vibrations based on an acoustic signal equipped with a dual magnet that minimizes the loss of vibration generated by the vibration and increases the transmission efficiency to improve the accuracy of adjustment.

In general, cold brew coffee is coffee brewed using cold or room temperature water, and has less bitterness and a softer flavor compared to coffee according to the traditional method. As a result, the number of people who enjoy cold brew coffee is increasing exponentially.

On the other hand, cold brew coffee is divided into point type and leaching type cold brew coffee according to the manufacturing method. Brewed cold brew coffee is produced by dripping water falling by gravity into ground coffee and permeating it, and brewing cold brew coffee is prepared by brewing ground coffee in a container filled with water. However, cold brew coffee has a disadvantage in that it takes a long time regardless of any manufacturing method, so it is difficult to sell it for commercial use.
