Orientation-Responsive Acoustic Driver Selection

US Patent:
2012026, Oct 18, 2012
Filed:
Apr 14, 2011
Appl. No.:
13/086976
Inventors:
John Joyce - Canton MA, US
Eric J. Freeman - Sutton MA, US
International Classification:
H03F 99/00, H04R 1/02
US Classification:
381120, 381387
Abstract:
An audio device incorporates a first acoustic driver having a first direction of maximum acoustic radiation and a second acoustic driver having a second direction of maximum acoustic radiation, where the first and second directions of maximum acoustic radiation are not in parallel, and where the audio device employs the first acoustic driver or the second acoustic driver in acoustically outputting a sound of a predetermined range of frequencies in response to the orientation of the casing of the audio device relative to the direction of the force of gravity.

Switchable Wired-Wireless Electromagnetic Signal Communication

US Patent:
8594569, Nov 26, 2013
Filed:
Mar 19, 2010
Appl. No.:
12/727658
Inventors:
Matthew R. Hicks - Marlborough MA, US
John Joyce - Canton MA, US
Assignee:
Bose Corporation - Framingham MA
International Classification:
H04B 7/00
US Classification:
455 412, 455 413, 455 661
Abstract:
An apparatus include a first electronic component having first interface circuitry configured to generate an electromagnetic signal. The first electronic component is switchable such that in a first mode of operation, the first interface circuitry is configured to transmit the generated electromagnetic signal via a first antenna, and in a second mode of operation, the first interface circuitry is configured to transmit the electromagnetic signal to a second electronic component via a constrained signal path coupling the first electronic component and the second electronic component. The generated electromagnetic signal may be a radio frequency signal or an optical signal.

Orientation-Responsive Acoustic Array Control

US Patent:
2012026, Oct 18, 2012
Filed:
Apr 14, 2011
Appl. No.:
13/087002
Inventors:
Eric J. Freeman - Sutton MA, US
John Joyce - Canton MA, US
Assignee:
BOSE CORPORATION - Framingham MA
International Classification:
H03F 99/00, H04R 1/02
US Classification:
381120, 381387
Abstract:
An audio device incorporates a plurality of acoustic drivers and employs them to form either a first acoustic interference array generating destructive interference in a first direction from the plurality of acoustic drivers or a second acoustic interference array generating destructive interference in a second direction from the plurality of acoustic drivers in response to the orientation of the casing of the audio device relative to the direction of the force of gravity.
