Abstract: A rotating apparatus for a liquid crystal display comprises: a main body provided with a mounting recess having a predetermined radius of curvature; a liquid crystal display provided, at its bottom surface, with a curved portion corresponding to the mounting recess so that the curved portion rotates in surface contact with the surface of the mounting recess; and an angle regulator for guiding the rotation, in a predetermined direction, of the LCD and setting a position of the LCD when rotated to a predetermined position. The angle regulator includes: a plurality of bosses protruding from the bottom surface of the LCD; guide holes formed along a curvature of the mounting recess so as to form passageways through which the bosses are rotated; guide rails protruding from both sides of the guide holes toward the bottom surface of the mounting recess; and sliders which slide along the guide rails and engage the bosses.

Abstract: A speaker assembly includes a speaker mounted within a housing having a front plate and a base plate. The speaker is inclined with respect to the front plate. The base plate includes one of an inclined type structure, a convex type structure, a radial rib type structure having radial ribs, and an uneven structure having projections. The front plate includes holes of certain shapes such as having two half holes formed on opposite sides of front plate and communicating with each other through a common opening formed between the two half holes.
