Abstract:

A loudspeaker system having an enclosure having a narrow opening or slot for radiating high frequency acoustic energy. The loudspeaker system has a cover member defining a slot between the cover member and a boundary of a listening space. The loudspeaker system may also include a fixed or adaptive equalizer for modifying frequency response anomalies resulting from the interaction of the acoustic energy, the narrow opening, and the boundary.

International Classification:

H04R 1/20

US Classification:

381338, 381337, 381339, 381341, 381345, 381351

Abstract:

A loudspeaker assembly, including an acoustic waveguide; an acoustic driver mounted in the waveguide so that a first surface radiates sound waves into the waveguide so that the sound waves are radiated from the waveguide; and an acoustic volume acoustically coupled to the acoustic waveguide for increasing the amplitude of the sound waves radiated from the acoustic waveguide.

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.

Inventors:

John J. Breen - Southborough MA, US
Richard J. Carbone - Sterling MA, US
Eric J. Freeman - Sutton MA, US

International Classification:

H04R 1/02

US Classification:

381387

Abstract:

An audio device incorporates first acoustic driver at least partially overlain by a first acoustic reflector to define a first effective direction of maximum acoustic radiation and a second acoustic driver at least partially overlain by a second acoustic reflector to define a second effective direction of maximum acoustic radiation, wherein when the audio device is positioned in a room such that the direction of maximum acoustic radiation of the first acoustic driver is substantially perpendicular to the direction of the force of gravity, the first effective direction of maximum acoustic radiation is bent more towards a listening position at which a listener is expected to be located than the first direction of maximum acoustic radiation and away from a floor, and the second effective direction of maximum acoustic radiation is bent more towards the listening position than the second direction of maximum acoustic radiation and away from a wall.

International Classification:

G10L 25/84
H04R 25/00

Abstract:

An audio system and method for generating improved augmented hearing effects in real-time. The system includes a wearable audio device arranged to obtain audio that includes a voice signal associated with a user and an environmental signal associated with other audio picked up by the wearable audio device that does not includes the user's voice. In some implementations, at least one processor of the wearable audio device is configured to isolate the voice signal from the environmental signal such that augmented hearing effects can be applied to the voice signal and/or the environmental signal, independently. In some implementations, augmented hearing effects are designated by a signal augmentation profile generated or stored in the wearable audio device such that the total time between receipt of the audio signal and the modifications and/or transformations to the respective audio signals does not exceed 100 ms.

G06F 16/9032

Abstract:

A method of operating a situationally aware speaker associated with a virtual personal assistant (VPA) service provider that comprises receiving an indication of at least one parameter of an environment proximate the situationally aware speaker, and delivering the response to the vocal query to the user formatted as speech through an audio output of the situationally aware speaker, at least one audio parameter of the response set based on the indication of the at least one parameter.
