Acoustic noise reduction apparatus for personal computers and electronics
First Claim
1. An apparatus for acoustic noise reduction of noise generated by one or more fans of an electronic device comprising:
- a removably adjustable acoustic barrier member externally attached to the electronic device around the one or more fans, the barrier member having an inner surface;
acoustic absorbing material attached to the inner surface of the barrier member;
a means for stabilizing the barrier member to the electronic device;
wherein the barrier member is adjustable to a width of the device and attached to the device such that airflow loss from the one or more fans is negligible.

Abstract
An acoustic noise reduction accessory apparatus attachable or made integral to a personal computer or other electronics equipment. The apparatus reduces acoustic noise emitted from the rear of the computer and in particular reduces the acoustic noise from circulating fans. The apparatus comprises an acoustic barrier or shielding member. The barrier is shaped in various forms externally of the computer or integrally extending from the back of the computer around one or more fans of the computer; the acoustic barrier member allows for minimum airflow reduction. Acoustic absorbing material is layered upon the acoustic barrier and may be combined with vibration absorbing material. The barrier may be shaped from solid or flexible members to accommodate different sized electronics and formed to include baffles and structures to direct airflow while absorbing noise; and may be made adjustable by one or more slidable members. The apparatus is easily assembled and collapsible for storage.

18. An acoustic noise reduction apparatus for reducing noise generated by one or more fans of a computer tower comprising:
-
a removably adjustable acoustic barrier member externally attached to a rear of a chassis of the computer tower around the one or more fans, the barrier member further comprising a plurality of removable sections, including a firm cantilever section and one or more flexible side sections, wherein each section having an inner surface;
at least one pair of guide rails disposed on the cantilever section for a side section to slide into for adjusting the positioning of a side section to a width of the computer chassis;
acoustic absorbing material attached to the inner surface of the barrier member sections;
a means for attaching the barrier member sections to the computer tower chassis;
wherein the barrier member sections are attached to the chassis such that airflow from the one or more fans is redirected and airflow loss is negligible. - View Dependent Claims (19, 20)
