Abstract
An apparatus for reducing noise emitted by an electronic or other device and such devices incorporating the noise reducing apparatus. A mechanism for acoustically filtering undesired noise from an electronic device, particularly noise generated by a cooling mechanism is disclosed. In a preferred embodiment, noise is filtered at least in part with an appropriately dimensioned compressible air space. The noise reducing or filtering mechanism may be utilized with portable and non-portable computers, stereos, entertainment equipment and other devices.
