PURPOSE: An air blower for reducing noise is provided to have no need of expensive sound-absorbing/soundproof materials and to implement cost down and light weight by employing a noise reduction structure. CONSTITUTION: An air blower for reducing noise(100) has a resonator structure communicated with an internal air path of blower housing while having a sealed space toward the outside of the blower housing(101) to reduce noise occurring in the rotation of a blade. The resonator structure has an outer housing forming the sealed space while surrounding the outside of the blower housing. |
