Abstract
An entertainment device has a metal shielding member that covers the CPU and image processing unit and a flexible sheet that is interposed between the CPU and metal shielding member. The metal shielding member contains metal oxide magnetic particles for cutting off electromagnetic radiation generated from the CPU and image processing unit, while the flexible sheet is positioned to radiate heat away from the CPU and image processing unit.
