Abstract: A portable computer is equipped with a sound capability by plugging a personal computer memory card international association (PCMCIA) card having an on-board master speaker module into a PCMCIA slot. A slave speaker module in wireless communication with the master speaker module may also be used to radiate sound.

Abstract: A computer speaker assembly 22 is disclosed and includes a tweeter or high-frequency speaker 72 which may be selectively moved in relation to a mid-range-woofer speaker 30. Such movement is accomplished by means of a gear 64 and detent 62 arrangement.

Abstract: A show bar assembly for attachment to side panels of a pick-up truck or like vehicles capable of being adjusted and mounted on such vehicles of a plurality of different sizes and configurations and support a variety of automotive light accessories and the like at different locations as chosen by the owner. The show bar assembly comprises an upright front bar formed of three tubular members collectively forming an inverted U-shaped first bar unit to extend above the side panels of the truck and a second bar unit also collectively forming an inverted U-shaped angled bracing bar unit with the top section thereof immediately adjacent and paralleling the top section of the first bar unit. Each of these side tube sections of the first and second bar units have a mounting plate at the respective lower ends thereof for fixing the lower end portions thereof to truck side panels in deliberate mechanical tensioned relation minimizing vibration and looseness between component parts.

Abstract: A side bar assembly for attachment to a chassis of a pick-up truck, off-road vehicle or the like capable of being mounted on such vehicles of a plurality of different sizes and configurations, wherein the side bar assembly is formed of a pair of substantially L-shaped tubular members as half-bar tube sections to collectively form a generally U-shaped side bar to extend laterally from a side of the vehicle. A substantially semi-cylindrical connector sleeve defining a concave tube-gripping recess receives the aligned end portions of the tubular members with the connector sleeve partially encircling and gripping the adjacent portions of the tubular members over more than half the circumferential extent of each, and mounting brackets are provided for bolt securement to the vehicle chassis to receive and support end portions of the side legs therein.

Abstract: A side bar assembly for attachment to a chassis of different sizes of pick-up trucks, the side bar assembly including a pair of substantially L-shaped tubular members forming half-bar tube sections to collectively form a generally U-shaped side bar to extend laterally from a side of the vehicle, and a cylindrical connector sleeve having a central bore corresponding substantially to the outer diameter of the tube legs to receive the latter therein in alignment with each other with the connector sleeve encircling the adjacent portions of the tube legs over more than half the circumferential extent of each and a pair of mounting brackets to receive end portions of the side bar legs therein. The connector sleeve also includes a thickened portion defining an upwardly facing flat step surface at the top of the sleeve.

Abstract: A tower-type speaker cabinet assembly for plural speakers of a high fidelity audio system, including a vertically elongated tower cabinet having a pair of front wall segments adjacent the uppermost and lowermost ends of the tower speaker cabinet and an intermediate forwardly opening cavity extending between the upper and lower front wall segments, a pair of vertically spaced large subwoofer speakers in the respective upper and lower front wall segments with associated inner cabinets forming sound boxes therefor, and a swivelled movable center subcabinet spanning the vertical distance between said front wall segments, having a woofer, a mid-bass speaker and a pair of tweeters carried by a front wall portion of the center subcabinet in vertical alignment. The subcabinet has a range of swivel movement horizontally through predetermined angles about a vertical axis located a short distance rearwardly from the front wall of the swivelled subcabinet.

Abstract: A sun roof assembly and seal therefor comprises a flexible ring shaped member having a base with a groove therein for receiving a continuous rigid bead on the frame of the sun roof and a tubular bulb positioned on the upper wall of the base. When the cover of the sun roof is opened the upper wall of the bulb springs upwardly above the level of the roof in which the sun roof is installed, but when the cover is closed, the upper wall of the bulk is compressed against the base above the rigid bead to seal the sun roof against leakage.

Abstract: An adaptor for playing a magnetic tape cassette in a tape player for 8-track endless tape cartridges, including an adaptor housing whose horizontal width and depth dimensions and peripheral shape adjacent the bottom thereof are substantially the same as that of the endless tape cartridge to fit in the cartridge-receiving cavity of the tape player. The housing is shaped to form an upwardly opening well for receiving the magnetic tape cassette, and has a tape driving capstan for driving the cassette tape, and a capstan drive train for selectively driving the capstan from the tape drive of the cartridge player, including a pivoted power takeoff lever and pulley to couple and decouple with the cartridge tape drive, and a pivoted function control lever having an end portion movable relative to the takeoff lever to position the latter at non-driven and release positions.

Abstract: A multirange thin speaker assembly for installation in automobile doors and like constricted space installations in compact automobiles and the like with the front of the assembly facing toward the automobile interior, including a main speaker section having a speaker basket frame provided with mounting ears for receiving front mounting screws to fix the speaker basket frame against an interior wall portion of the automobile door. The main speaker section includes a woofer speaker unit and a bridge member supported from the basket frame carrying a tweeter speaker unit. A front grille panel of unitary plastic material has a pair of transversely spaced arcuate rear snap ring segments forming an interrupted annular ring projecting rearwardly from the panel to interfit in an anchor ring member carried by the basket frame, each having radially outwardly projecting bead formations to snap behind retaining shoulders of the anchor ring to fasten the grille panel to the anchor ring.
