Filed:

Sep 22, 1999

Appl. No.:

09/404451

Inventors:

Brian Cox - Somerville MA
Aaron Linn - York ME
Leif Blackmon - Medfield WA

Assignee:

Boston Acoustics, Inc. - Peabody MA

International Classification:

H04R 2500

US Classification:

381397, 181199

Abstract:

A cooling mechanism is provided for an audio speaker, which mechanism includes a plate of a thermally conductive material mounted between the driver mechanism of the speaker and the speaker basket and extending from the voice coil gap to the outside of the speaker. The spacing between this plate and the voice coil is preferably kept as small as possible. The plate is preferably a vent plate having a plurality of radial vents extending along the width of the plate from the voice coil gap side thereof to the side facing the outside of the speaker. Such a vent plate, in addition to providing radiant cooling, also provides cooling via air flow as well as conduction and convection cooling. The vents are sized and shaped so as to minimize any turbulence, and thus any audible air noise.

Assignee:

Boston Acoustic, Inc. - Peabody MA

International Classification:

H04R 25/00

US Classification:

381182, 381186, 381386

Abstract:

A loudspeaker system designed for ceiling installation. The system includes a woofer, a midrange speaker and a tweeter commonly supported on a rotatable support member which in turn is supported on and is rotatable with respect to an annular rim that is designed to be fixed about an opening in the ceiling. The woofer is aligned at one acute angle and the midrange speaker and tweeter at another acute angle to the annular rim. The mid range speaker and tweeter are partially segregated from the woofer by a baffle.

International Classification:

H04R 1/02

US Classification:

381386, 381387, 381389, 381394, 381395

Abstract:

An audio speaker contains a tweeter capable of continuous rotation, where the audio speaker contains the tweeter and an axis mount assembly. The tweeter is removably connected to the axis mount assembly. The audio speaker also contains a first connection member capable of maintaining electrical communication with the axis mount assembly throughout continuous rotation of the axis mount assembly. The axis mount assembly contains a terminal plate connected to a bottom portion of the tweeter, where the terminal plate maintains electrical communication with the tweeter. The axis mount assembly also contains an axis mount faceplate capable of receiving the terminal plate and tweeter within an indented portion of a top portion of the axis mount faceplate. The axis mount assembly further contains an axis mount spacer and a second connection member that maintains electrical communication with the first connection member throughout continuous rotation of the axis mount assembly.
