FIELD OF ART
The present invention relates to a sound diffuser for a ceiling-mounted audio system in which only the sound diffuser is visible below the ceiling. The present invention more particularly relates to a sound diffuser that can be printed upon to match a ceiling surface pattern.
BACKGROUND OF THE INVENTION
Ceiling-mounted speakers are frequently used in office complexes and schools. While a variety of audio systems above the ceiling have been developed, the appearance of ceiling speakers has not changed in decades. While size may vary, typical ceiling speakers still look, from the point of view of people in the room below the ceiling, the same as they have for decades: a frame surrounding a speaker grill. This monotony limits the options of architects and interior designers in creating comfortable spaces.
SUMMARY OF THE INVENTION
Briefly described, the invention includes a sound diffuser having a downward-facing (when installed) flat disc cover plate and a flat barrel flange that assists in clamping a ceiling tile. The downward facing surfaces of the disc cover plate and a flat ring releasably attached to, and covering, the barrel flange are printable surfaces. The ring and the disc cover plate are preferably steel and are held in place with magnets. The ring and the disc cover plate can be rotated to align patterns printed on the ring and the disc cover plate to align to a pattern on the ceiling and to each other. Three-dimensional printing of the ring and/or the disc cover plate is included. The diffuser is preferably used in conjunction with the SMALL CEILING SPEAKER SYSTEM of U.S. patent application Ser. No. 15/710,654, the entire contents of which are incorporated herein by reference.

Diffuser barrel 108 includes a threaded hub 114 supported by arms 112 (one of three labeled) and an inner downwardly extending rim 146. Diffuser barrel 108 includes a flat annular bottom perimeter flange 110 that supports barrel magnet cups 118, 120, and 122 that fixedly receive magnets to retain steel ring 124. Steel ring 124 has an inner perimeter 148 that slidingly engages downwardly extending rim 146 when steel ring 124 is rotated. The bottom surface 126 of steel ring 124 is a printable surface. The bottom side of diffuser body 128 has a central hub 132 with threads 134 that align, during assembly, with threads in barrel hub 114. The bottom side of diffuser body 128 includes a downward perimeter rim 130 and diffuser magnet cups 136, 138, and 140, each of which fixedly receives a diffuser magnet 402 (see FIG. 4) to retain steel disc cover plate 142. Steel disc cover plate 142 includes a printable bottom surface 144.
Acoustic channel shell 102 is preferably made of injection molded plastic. Diffuser barrel 108 and diffuser body 128 are also preferably made of injection molded plastic. The magnets 402 are preferably rare earth magnets 402. While the ring 124 and the disc 142 are preferably made of steel, in various other embodiments, respective other magnetically attractable materials with printable surfaces (including composites) may be used. In various embodiments, respective various materials that meet the functional requirements of the preferred materials may be used.
FIG. 2 is a bottom-side perspective view illustrating the exemplary embodiment of the printable diffuser 100 of FIG. 1, according to a preferred embodiment of the present invention. Steel ring 124 is shown magnetically attached to flange 110. The advantage of the magnetic attachment is that ring 126 can be manually rotated around downwardly extending rim 146 to align a complex pattern on the printable surface 126 to a pattern on the ceiling. Steel disc cover plate 142 is magnetically and releasably attached to diffuser body 128. The advantage of the magnetic attachment is that steel disc cover plate 142 may be manually rotated to align a pattern on bottom surface 144 of the disc cover plate with a pattern on the steel ring bottom surface 126 and/or a pattern on the ceiling.
