Abstract
A speaker unit includes first and second drivers carried by first and second enclosures. A first linkage supports the second driver enclosure relative to the first driver enclosure and provides at least two positional degrees of freedom of movement of the second driver enclosure relative to the first driver enclosure.
Claims27
A speaker system comprising:
- a first driver;
- a second driver;
- a first driver enclosure carrying the first driver;
- a second driver enclosure carrying the second driver;
- and
- a first linkage supporting the second driver enclosure relative to the first driver enclosure and providing at least two positional degrees of freedom of movement of the second driver enclosure relative to the first driver enclosure effective to provide phase alignment adjustment of the first and second drivers not dependent on changes in relative orientation.

A speaker system comprising:
- a first driver;
- a second driver;
- a first driver enclosure carrying the first driver;
- a second driver enclosure camming the second driver;
- and
- a first linkage supporting the second driver enclosure relative to the first driver enclosure and providing at least two positional degrees of freedom of movement of the second driver enclosure relative to the first driver enclosure, and wherein the first linkage comprises an arm having:
- a proximal link
- a first joint coupling the proximal link to the base for relative rotation about a vertical first axis;
- a first intermediate link;
- a second joint coupling the proximal link to the first intermediate link for relative rotation about a horizontal second axis;
- a second intermediate link;
- a third joint coupling the first intermediate link to the second intermediate link for relative rotation about a third axis parallel to and spaced apart from the second axis;
- a distal link holding the second enclosure;
- and
- a fourth joint coupling the distal link to the second intermediate link for relative rotation about a fourth axis parallel to and spaced apart from the third first axis.
