    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: A speaker unit includes a speaker housing having a lower portion and an upper portion. A drive unit is housed in the upper portion for producing and outputting sound, with the drive unit having a central axis, and a sound mirror is housed in the lower portion for reflecting the sound output by the drive unit. The mirror has a generally conical surface facing the drive unit for redirecting sound therefrom into a generally horizontal direction and a cone shape, with an apex of the cone being closest to the drive unit. A supporter supports the drive unit in a cantilever type manner above the sound mirror, and the center axis of the drive unit is offset from the apex of the sound mirror, with the drive unit supporter positioned at substantially the opposite side of the apex than the center of the drive unit.
