Document Type and Number:
WIPO Patent Application WO/2018/216944
Kind Code:
A1
Abstract:
A cold brew coffee extractor for adjusting sonic vibrations on the basis of acoustic signals is disclosed. The cold brew coffee extractor for adjusting sonic vibrations on the basis of acoustic signals, according to one embodiment of the present invention, comprises: a current support unit extendedly formed in one direction such that an alternating current is applied in the tangential direction of an outer peripheral part; a magnetic vibration unit, which accommodates end of the current support unit therein so as to form a magnetic field in the direction of crossing the current support unit, thereby being vibrated in the lengthwise direction of the current support unit by polarity changes of the alternating current; a plate unit coupled with the magnetic vibration unit so as to transmit the vibrations to fluid containing particulate matter; and a vibration adjusting circuit, which adjusts vibrations on the basis of only setting information inputted through a user interface in a first mode, and adjusts vibrations on the basis of the setting information and an external sound source in a second mode.
