Preferably, described active fall air purifier of making an uproar, wherein, the rotating shaft of described drainage blower fan be also provided with velocity gauge 8, for gather raw noise information send to described controller board card.
Preferably, described active falling air purifier of making an uproar, wherein, be also provided with pugging between described blast inlet loudspeaker support and blast inlet loud speaker, the opening direction of this pugging is consistent with air current flow direction.
Preferably, described active air purifier of making an uproar falls, wherein, described in go out air port loudspeaker support and go out between the loud speaker of air port, to be also provided with pugging, the opening direction of this pugging is consistent with air current flow direction.
Preferably, described active falling air purifier of making an uproar, wherein, described controller board card comprises the power amplifier module that can drive described loud speaker.
Preferably, described active fall air purifier of making an uproar, wherein, between described cleaner blast inlet and air purifying filter mesh, also it is provided with guide duct.
The beneficial effects of the utility model: this case provides a kind of active falls air purifier of making an uproar, controller board card is utilized to considerably reduce the noise of air purifier, and by the structure design between loudspeaker support and loud speaker so that volume, weight significantly do not increase.
