Patent ID: 8181736

Claim:
An acoustic lens for improving directivity performance of a speaker assembly comprising: a member including a first surface and a second surface; the member further includes a first union of the first surface and the second surface, where the first union forms a continuous internal lip to define a plurality of protrusions surrounding an orifice; the first surface and the second surface further unite to form a perimeter of the member, where the perimeter includes a mounting feature; where the mounting feature includes a foot portion conformed to mate with a speaker to form a substantially air tight seal between the speaker and the foot portion of the member; where each of the protrusions includes an outer contour that intersects with the outer contour of an adjacent one of the protrusions to form a plurality of outer vertices with respect to a central point of the orifice; and where each of the protrusions further includes interiorly located vertices with respect to the central point of the orifice, where the first surface and the second surface unite to form a plurality of perimeters of a plurality of auxiliary apertures, where at least one of the auxiliary apertures is located in a portion of one of the protrusions.
