Patent ID: 7991175

Claim:
A speaker system, comprising speaker units mounted in the speaker system, wherein the speaker units are configured into different positions to increase acoustical performance perceived by a user, wherein said speaker system further comprises contains a mechanical structure comprising four members: a first member, wherein said first member has any geometrical shape, wherein said first member has a first surface and defining a circular innermost periphery of said first member; a second member, wherein said second member is arranged within the circular periphery provided on the first member, such that the second member is rotatable around an axis perpendicular to, or close to being perpendicular to, a plane of the first surface of the first member, and with the second member fully or partly having a material surface; a third member being an integrated part of the second member or being a separate object mounted on top of the second member, and wherein said third member includes one or more of the speaker units mounted to deliver acoustical output directed away from a surface of the third member; a fourth member, wherein said fourth member further comprises support structure including a hinge for the third member, and the hinge enables the third member to be tiltable around an axis horizontal to, or close to being horizontal to, a plane of a surface of a second member and with the fourth member attached to the second member, wherein the speaker system further comprises at least one correction filter provided in a signal path of the speaker unit, said at least one correction filter being configured to filter outputs of said speaker units based on a series of filter attributes, wherein a set of said filter attributes are selected based on the positions of the speaker units, and wherein a predefined plurality of individual set of filter attributes related to speaker unit positions for each of the one or more speaker units are replaced with data from an external source.
