Apple has found itself on the wrong side of another patent lawsuit. Lucasfilm-owned THX sued Apple yesterday over a claimed infringed patent relating to the speaker designs found on the new iMacs, iPhones, and iPads.
Patent no. 7433483, filed in 2008 by THX, protects “narrow profile sound systems” that shoot sound out a “narrow sound duct.” The exact patent description reads as follows:
A narrow profile speaker unit comprises at least one speaker outputting sound towards an internal surface and through a duct with an output terminus, such as a slot, having a narrow dimension, effectively changing the cross-section of the speaker’s audio output wave. A pair of speakers may face one another, outputting sound towards a common output slot. Multiple pairs of speakers may be used to form an inline speaker unit for increased sound output. A slotted speaker unit may include multiple speakers facing the same direction, towards a groundplane or reflecting surface, and having parallel apertures for allowing sound radiation. The speaker units may be integral with or attached to electronic appliances such as desktop computers or flatscreen devices, or may be used in automobiles or other contexts.
THX was founded in 1983 as a division of Lucasfilm and was re-booted in 2001 as an independent company. Apple and THX have never had friction in the past, and, just two months ago, THX released ‘THX tune-up’. It’s an app that allows you to adjust your “TV, projector and speakers” all from your iPhone or iPad.
