Patent number: 9913012Abstract: An acoustic device includes an acoustic assembly that defines a first acoustic volume. The acoustic assembly includes at least one passive radiator in acoustic communication with the first acoustic volume. A first electro-acoustic driver is configured to acoustically energize the first acoustic volume so as to drive the piston in oscillatory motion. The acoustic device also includes a housing within which the acoustic assembly is disposed. The housing has a curved inner surface. The passive radiator has a curvature which conforms to the curvature of the curved inner surface of the housing so as to reduce unused space between the at least one passive radiator and the curved inner surface of the housing.Type: GrantFiled: September 12, 2014Date of Patent: March 6, 2018Assignee: Bose CorporationInventors: Chester Smith Williams, Brandon Westley, Roman N.

Patent number: 9554201Abstract: An audio device includes a housing having first and second support surfaces for supporting the device at different orientations relative to the surface on which the device is placed, a driver to output sound in a radiating pattern associated with a first axis of the driver, and an orientation sensor to detect a direction of a force of gravity. A control circuit coupled to the driver and the orientation sensor determines the direction of the force of gravity relative to the first axis and whether the first axis is oriented to one of a first angle of elevation associated with physically supporting the device by the first surface and a second angle of elevation associated with physically supporting the device by the second surface. The circuit can alters the output by the driver based on the first axis being oriented to the first or second angles of elevation.Type: GrantFiled: March 30, 2015Date of Patent: January 24, 2017Assignee: Bose CorporationInventors: Chester Smith Williams, Roman N.

Publication number: 20160219362Abstract: A balanced acoustic device includes an enclosure defining an acoustic chamber, a first passive radiator diaphragm having an active driver assembly and a second passive radiator diaphragm having a plurality of active driver assemblies that are laterally offset. The moving mass of the first passive radiator assembly is substantially equal to the moving mass of the second passive radiator diaphragm. The lateral offsets of the active driver assemblies in the second passive radiator diaphragm eliminate their interference within the enclosure with the active driver assembly of the first passive radiator diaphragm. Advantageously, a smaller distance between the two passive radiator diaphragms is allowed and therefore a smaller enclosure is possible.Type: ApplicationFiled: January 26, 2015Publication date: July 28, 2016Inventors: Roman Litovsky, Chester Smith Williams
