Abstract
A display apparatus comprises at least one speaker and a cathode-ray tube (CRT) secured within an enclosure to a plurality of mounting bosses . The cathode-ray tube has an evacuated envelope with a substantially rectangular-shaped faceplate panel having four corners and a viewing portion extending to a peripheral sidewall . The viewing portion has a luminescent line screen on the interior surface thereof The viewing portion including two orthogonal axes, a major axis, X, parallel to a longer dimension of the viewing portion and a minor axis, Y, parallel to a smaller dimension of the viewing portion. The CRT has therein an electron gun , capable of generating at least one electron beam, aligned along a central longitudinal axis, Z, of the CRT that is perpendicular to the major and minor axes. The CRT also has a color selection electrode in proximity to the interior surface of the viewing portion of the faceplate panel . An implosion protection band extends around the sidewall of the faceplate panel . At least four mounting lugs , each having a base portion and an attachment portion , with a mounting aperture , therethrough, cooperate with the implosion protection band 44 to facilitate securing the CRT within the enclosure . The attachment portion , of each of the mounting lugs , is aligned along the central longitudinal axis, Z, of the CRT and parallel to at least one of the two orthogonal axes, X, Y, to strengthen the attachment portion and reduce microphonics induced by the speaker
