METHOD AND SYSTEM FOR REDUCING FAN NOISE AS WELL AS ELECTRONIC DEVICE USING THE SAME

摘要

A noise-reducing fan system (1), comprising a motor (11), a fan body (12), a plurality of magnetic-inducing elements (13), a magnetic field generator (14) and a noise-reducing sound source device (15), is provided. The fan body (12) is mounted on the motor (11). The fan body (12) comprises a plurality of blades (121), on which the plurality of magnetic-inducing elements (13) is disposed, respectively. The magnetic field generator (14), which may generate a magnetic field, is employed for driving the plurality of magnetic-inducing elements (13) to vibrate the plurality of blades (121) and generate a vibration sound, so that at least one portion of the noise emitted from the fan body (12) as rotating may be counterbalanced. The noise-reducing sound source device (15) is disposed on a predetermined position and may send out a noise-reducing sound, so that the noise-reducing sound may counterbalance at least the other portion of the noise emitted from the fan body (12) as rotating.
