A speaker system for a picture receiver provides for lessening of the casing width of the picture receiver while assuring highly uniform acoustic characteristic at listening points in a sufficiently broad range. The speaker system for picture receiver and its speaker installing method comprises a first speaker for reproducing medium and high range sound at the right and left of the screen of a picture receiver and a second speaker for reproducing medium and low range sound under the screen, wherein the speaker system is set in such place that when a listening point is set at a position a first distance apart from the picture receiver and within a second distance from the front axis at the center of the right and left of the screen, the distance from the first speaker to the listening point is R, the distance from the second speaker to the listening point is R, and the crossover frequency is f, then R, Rand f satisfy the specified relative formula.

Speaker system for picture receiver and speaker installing method

A cathode-ray tube (CRT) holding device holds a CRT from the rear side by a rib section having a shape similar to that of a funnel of the CRT and extending in plural directions. The rib section has a section having shaped in a recessed groove, and a degaussing coil is disposed in the groove. The CRT holding device has a low cost and a raised recycling rate. Without increasing the number of parts, the degaussing coil can be mounted.

Video appliance, holding device, and manufacturing method of holding device

A television receiving apparatus having a video tape recorder unit therein with a function for preventing an electric shock, for preventing a user from inserting his fingers into a cabinet when the video tape recorder unit is removed from the cabinet for repair or the like, includes a locking mechanism for locking a controller door panel at a position where it is closed. The controller door panel is used for operating the video tape recorder unit contained in the apparatus. In order to surely obtain security of the user even when the locking operation is forgotten, the apparatus further includes a mechanism for interrupting supply of electric power to a television receiver when the absence of the video tape recorder unit in the cabinet is detected and when the controller door panel is detected to be opened at and more than a predetermined angle. A possibility that the user will receive an electric shock can thus be eliminated.
