摘要:
A computer case having a base (10) incorporating a keyboard (14) which in the closed condition of the case is covered by a lid (12) having its display uppermost, the case opening by a mechanism enabling the lid to slide rearwardly and incline relatively to the base so as to present the display forwardly behind the keyboard.

A vibration dampening speaker mounting assembly includes a flush-mountable frame for mounting to a wall or ceiling, at least one vibration dampening member, and a baffle for supporting a single or multi-driver transducer array. The at least one vibration dampening member is disposed between the baffle and the frame to reduce acoustic distortions coupled to the wall/ceiling from the baffle. Fasteners are provided that permit installation of the baffle to the frame without tools while avoiding significant acoustic coupling between the baffle and the frame through the fasteners.

摘要:
A loudspeaker unit is provided for attachment at an elevated position within a listening space. It has a drive unit for producing a beam of treble sound, and a sound mirror that distributes a beam from the sound unit over a wide angular extent both horizontally and vertically with a generally consistent amplitude of perceptible sound. The unit may further comprise an angled mid range and low frequency drive unit. The unit demountably clips into a support bracket that can be carried by a post or fixed directly to the wall. Signal supply is via connectors in the bracket so that as the unit is clipped in place, the electrical connections are established. The speaker is quadrant shaped when viewed in plan and lends itself to installation in groups and clusters (FIG. 13).
摘要:
Loudspeaker mounting apparatus that permits mounting of a loudspeaker at an angle to a mounting surface. In one embodiment the apparatus comprises an assembly that includes a frame member that is flush mountable in a cutout in the mounting surface. The frame member includes an angled flange that is employed for the mounting of a cooperative baffle. The front of the baffle is recessed behind the mounting surface to permit a flush speaker installation. The baffle mounts to the angled flange of the frame member in one of two possible predetermined orientiations so as to disperse sound around a centerline that is either oriented normal to the mounting surface or at a predetermined angle from normal corresponding to the degree of angle incorporated into the frame and baffle assembly. In an alternative embodiment, a single panel-mount loudspeaker mounting frame is provided that has a speaker mounting surface angled with respect to the mounting surface so as to disperse sound around a centerline angled with respect to the plane of the wall or ceiling in which it is mounted. The speaker mounting surface is recessed within the wall when the the frame member is mounted in its intended mounting position so that the speaker will not extend into the room when the frame member is mounted to the wall or ceiling.
