DESCRIPTION:
BRIEF SUMMARY
The invention relates to television receivers having display screens with doors and, more particularly, to such television receivers having loudspeakers in their doors.
BACKGROUND OF THE INVENTION
A portable television receiver particularly suited for the youth market is a concept of the inventors, which television receiver is small enough and light enough to be easily transported by a child of nine or ten years of age and is suited for the playing of video games. In the interest of eliminating battery weight such television receiver, though portable, is normally powered by connection to electric power mains. A portable computer monitor particularly suited for the youth market, which computer monitor is small enough and light enough to be easily transported by a child of nine or ten years of age and is suited for the playing of video games, is a related concept of the inventors. Such a television set or computer monitor is termed "child-transportable" in this specification. Such a "child-transportable" television set or computer monitor is likely to be frequently moved by children apt to be careless when their thoughts are distracted by the prospect of playing video games. Protective covering of the display screen to reduce the likelihood of damage to the kinescope or liquid crystal display device during such moving (and of possible consequent injury to a child) is accordingly contemplated.
Moreover, the doors for closing over the display screen are hinged in order to facilitate the making of a portable television receiver that is "child-transportable", permitting the child to carry the receiver using handles on the left and right sides of the cabinet in a two-handed carry with the closed doors resting against the lower front torso. The portable television receiver designed particularly for the American youth market and for the playing of video games includes a supporting base for the cabinet, and a swivel-and-tilt mechanism, which not only facilitates adjusting the direction of direct viewing to suit a human viewer, but which alternatively facilitates adjusting the direction stereophonic music is radiated from the loudspeakers in the doors to suit a human listener.
U.S. Pat. No. 3,627,392 issued Dec. 14, 1971 to Finley Ruppersburg is entitled STEREO SOUND REPRODUCTION SYSTEM. Ruppersburg describes portable stereophonic-sound reproduction apparatus with a case having left-hand and right-hand swinging doors that open from the front of the case to a spread position. Loudspeakers mounted in the doors are arranged for directing stereophonic sound when the doors are opened to the spread position. The case encloses a swing-down phonograph record player with associated playback electronics.
Portable television receivers and computer monitors have used swiveled cabinets to facilitate adjusting the normal viewing direction. U.S. Pat. No. 5,243,434 issued Sep. 7, 1993 to Takashi Nodama and entitled SWIVEL DEVICE FOR A TELEVISION RECEIVER is evidence of this. The United Kingdom patent application GB 2 252 003 A of Jeong-Seop Lee and Woo-Jin Kim published Jul. 22, 1992 and entitled TURNTABLE FOR TELEVISION RECEIVER describes the use of a motorized turntable for adjusting the normal viewing direction of a television receiver provided with loudspeakers contained within the cabinet body that encloses the kinescope and positioned at the left and at the right of the kinescope viewing screen.
Large console and hutch television receivers of the past have employed doors to hide their display screens when the receivers are shut off; the doors were used primarily for cosmetic reasons, so as not to have to see the dead eye of a rasterless kinescope. At one time roll-front cabinets were common for European television receivers, the roll-front doors taking up less room when opened. Doors have also been used for cosmetic reasons in stereophonic audio systems. In U.S. Pat. No. 5,119,421 issued Jun. 2, 1992 and entitled STEREO SYSTEM CABINET WITH LOUDSPEAKER DOOR ASSEMBLY, Reime describes a stereo system cabinet with front-opening
