| 20110182440 | Woofer-less and enclosure-less loudspeaker system - A woofer-less and box-less loudspeaker system including a plurality of tweeter drivers is provided. The speaker system includes a plurality of drivers, each driver including a front face and a rear face with an axis of symmetry, each driver configured for propagating sound energy along the axis of each driver from the front face, wherein the sound energy includes low frequency and high frequency components; and a support structure for arranging the plurality of drivers in such a way that the axis extending from the rear face of each of the drivers converge in a single point in space, wherein as the sound is propagated along the axis of each driver from the front face, the high frequency components from each driver are evenly spaced and the low frequency components from each driver are reinforced by the low frequency components of adjacent drivers. | 07-28-2011 |
| 20110182449 | ENCLOSURE-LESS LOUDSPEAKER SYSTEM - A loudspeaker system is provided for uniformly emanating sound waves to a listening area. The loudspeaker system includes a plurality of drivers, where each driver includes a front face, a rear face, and an axis of symmetry extending substantially perpendicularly through both the front and rear face. Each driver is configured to emanate low and high frequency sound waves from its front face substantially along its axis of symmetry. The loudspeaker system also includes a support structure having an inner volume. The support structure is configured to support the drivers in an arrangement such that the front face of each driver is directed toward the inner volume and the axis of symmetry of each driver intersects a relatively small volume near a central point located at the center of the inner volume. A listening area for the loudspeaker system is outside of the inner volume of the support structure. | 07-28-2011 |

| 20110236654 | METHOD OF SURFACE TREATMENT AND SURFACE TREATED ARTICLE PROVIED BY THE SAME - A method of surface treatment and surface treated article provided by the same are disclosed. The method of surface treatment of the present invention comprises: providing a substrate; and forming a ceramic layer on a surface of the substrate by atomic layer deposition (ALD), wherein the ceramic layer has a thickness of 1 nm to 1000 nm. The method of surface treatment of the present invention utilizes an atomic layer deposition (ALD) method to form a ceramic layer on a surface of the substrate, in which the formed ceramic layer has excellent uniformity and is randomly and entirely coated on the surface of the substrate. Therefore, the substrate surface treated by the method of the present invention is able to have a color the same as or different to that of the surface of the substrate and simultaneously prevent oxidation/tarnish occurring. | 09-29-2011 |
