Abstract
A portable device includes a body including an L-shaped first member including a battery compartment, and a second member hingedly coupled to rear of the first member, the second member including a projection adapted to secure to an AV player, and a well for receiving a plug; a speaker assembly in the first member; a cable interconnected the speaker assembly and the plug, and a magnifying lens mounted on an opening of the first member and having an elevation substantially the same as a screen of the AV player. The plug is adapted to pull out of the well to electrically connect to the AV player. The magnifying lens is adapted to magnify images shown on the screen by 140% to 150% when a distance between the magnifying lens and the AV player is in the range of 40 mm to 50 mm with a TV-distortion less than 1%.
