ABSTRACT:
A low noise optical disk drive includes a top cover, a bottom base, a containing space defined between the top cover and the bottom base, a playing mechanism assembled in the containing space, and a noise absorbing device installed in the containing space. When the playing mechanism is holding the CD ROM and in an operating state, the rotation of the CD ROM generates a main air current within the containing space and therefore produces noise. The noise absorbing device is capable of absorbing the mechanical noise when the playing mechanism is in the operating state, as well, when the main air current flows through the noise absorbing device, the main air current is divided into a plurality of air currents of different directions so as to reduce the noise produced from the main air current.
