VACUUM CLEANER AND CONTROL METHOD THEREFOR

摘要

The present invention relates to a vacuum cleaner comprising: a flow pathway for guiding the suction or discharge of air; and a resonator linked to the flow pathway. The resonator is constituted so as to be able to change the resonance frequency to be cancelled out and thus, even if there is a change in the noise generated following a change in the driving mode of the vacuum cleaner, the resonance frequency of the resonator can be changed so as to cancel out same.
