DEVICE FOR REDUCING NOISE OF A DISK DRIVE, ESPECIALLY CAPABLE OF REDUCING NOISE EFFECTIVELY GENERATED INSIDE THE DISK DRIVE, WHILE FILTERING PARTICLES IN THE AIR

摘要

PURPOSE: A device for reducing noise of a disk drive is provided to absorb a noise generated inside a disk drive by an acoustic absorbing member disposed in a cover member, thereby effectively decreasing the noise generated through the cover member. CONSTITUTION: A noise reducing device(160) is disposed in a cover member(112). The noise reducing device(160) comprises as follows. A groove(162) is formed on an external side(112a) of the cover member(112) in predetermined depth. Plural pierced holes(164) are formed on a bottom side of the groove(162). An acoustic absorbing member(166) absorbs a noise generated inside a disk drive by being received within the groove(162). A cover plate(168) is attached to the external side(112a) of the cover member(112) in order to cover the acoustic absorbing member(166).
