Rockin’ Patent – Bose’s “Portable Audio System Having Waveguide Structure”

August 21, 2020

Rockin’ Patent: US Patent No. 8,103,035
Filed: 22 December 2006
Assignee (owner): Bose Corporation
Title: Portable Audio System Having Waveguide Structure
Abstract: “An apparatus includes a housing. A waveguide is located within the housing. The waveguide includes a first subsection that bends around a first axis and has a first cross-sectional area with an aspect ratio that is substantially different from unity. A second subsection bends around a second axis that is non-parallel to the first axis and includes a second cross-sectional area with an aspect ratio that is substantially different from unity. A third subsection acoustically couples the first subsection to the second subsection. The third subsection includes a third cross-sectional area with an aspect ration that varies between the first aspect ratio and the second aspect ratio”
What’s claimed: “An apparatus comprising: a housing; and a waveguide located within the housing, the waveguide comprising a first subsection that bends around a first axis and includes a first cross-sectional area with an aspect ratio that is substantially different from unity, a second subsection that bends around a second axis that is non-parallel to the first axis and includes a second cross-sectional area with an aspect ratio that is substantially different from unity, and a third subsection that acoustically couples the first subsection to the second subsection, the third subsection comprising a third cross-sectional area with an aspect ratio that varies between the first aspect ratio and the second aspect ratio; wherein at least one of the first, second, and third cross-sectional areas each comprise a long dimension and a short dimension, and wherein the first and the second cross-sectional areas bend around an axis parallel to the long dimension of the respective first and second subsection”
