Patent number: 10327073Abstract: Aspects of the present disclosure provide methods, apparatuses, and systems for closed-loop respiration entrainment based on spatialized audio signals. According to an aspect, based on a determined rate of a subject's respiration, spatialization of a virtual sound source is altered to simulate a distance or directionality to the subject. Simulating the distance, directionality, and/or source characteristics comprises processing sounds of the virtual sound source to generate a perception of the sounds being heard from one or more distances or directions with reference to the subject. The altered virtual sound source attempts to regulate the rate of respiration of the subject. An audio device outputs the sounds of the altered virtual sound source.Type: GrantFiled: August 31, 2018Date of Patent: June 18, 2019Assignee: BOSE CORPORATIONInventors: Dale McElhone, Mikaela Alison Shannon, Daniel Ross Tengelsen, Richard Eli Saffran, John Harlan Wendell

Patent number: 10313808Abstract: An electronic device having a device housing includes a loudspeaker and several microphones within the device housing. A control circuit is electrically coupled to the loudspeaker and microphones. The loudspeaker produces speech and/or music. The control circuit determines a statistical measure for a first data set representing individual impulse responses from the plurality of microphones and compares that to a predetermined statistical measure for a second data set representing individual object-free impulse responses from the plurality of microphones to determine if an object is near the device. The statistical measure may be variance and may be computed in the time domain. Variance may be calculated using differences between the individual impulse responses and a mean impulse response that is a linear combination of the impulse responses for the plurality of microphones. The control circuit may include echo cancellers to mitigate common signals and/or other acoustic sources.Type: GrantFiled: March 10, 2017Date of Patent: June 4, 2019Assignee: Apple Inc.Inventors: Sean A.

Patent number: 10142715Abstract: A small speaker for panel mounting in a hole as small as seventy five millimeters diameter in which access to the rear of the panel is not required. The small speaker uses spring-loaded flip dogs that are actuated by rotating a sound disperser that is connected to a hollow cylindrical mechanism having gear teeth on its external surface which engage flip dog gears on the top surfaces of the flip dogs. Internally, the hollow cylindrical mechanism has an indentation that supports a speaker baffle which, in turn supports a speaker bushing. A loudspeaker is attached to the speaker bushing near the speaker baffle. Two housing sections attach, spaced apart, to an annular frame on opposing sides and receive the hollow cylindrical mechanism rotationally therein.
