Abstract
An audio device having a housing including a first loudspeaker disposed in the housing and oriented to emit sound towards a top of the housing, a second loudspeaker disposed in the housing and oriented to emit sound towards a bottom of the housing, and a third loudspeaker disposed in the housing and oriented to emit sound radially outward from the housing of the audio device. Embodiments may include a microphone array disposed proximate the top of the audio device and encircling the first loudspeaker.
Claims20
An audio device comprising:
- a housing including an interior;
- a first cavity disposed within the interior, the first cavity having a first volume;
- a second cavity disposed within the interior, the second cavity having a second volume and acoustically sealed from the first cavity, the second volume being greater than the first volume;
- a third cavity disposed within the interior, the third cavity having a third volume and acoustically sealed from the first cavity and the second cavity, the third volume being less than the first volume;
- a first loudspeaker coupled to the housing and at least partially disposed in the first cavity, the first loudspeaker oriented to emit first sound towards a first side of the audio device;
- a second loudspeaker coupled to the housing and at least partially disposed in the second cavity, the second loudspeaker oriented to emit second sound towards a second side of the audio device, the second side being orthogonal to the first side;
- and
- a third loudspeaker coupled to the housing and at least partially disposed in the third cavity, the third loudspeaker oriented to emit third sound towards a third side of the audio device, the third side being opposite the first side.

A device comprising:
- a housing including an interior surface and an exterior surface, the housing having:
- a first cavity of a first size formed at least in part by the interior surface;
- a second cavity of a second size, different than the first size, formed at least in part by the interior surface, the second cavity being separate from the first cavity;
- and
- a third cavity of a third size, different than the second size, formed at least in part by the interior surface, the third cavity being separate from the first cavity and the second cavity;
- a first loudspeaker coupled to the exterior surface and at least partially disposed within the first cavity, the first loudspeaker oriented to emit first sound outward from the device in a first direction;
- a second loudspeaker coupled to the exterior surface and at least partially disposed within the second cavity, the second loudspeaker oriented to emit second sound outward from the device in a second direction that is different from the first direction;
- a third loudspeaker coupled to the exterior surface and at least partially disposed within the third cavity, the third loudspeaker oriented to emit third sound outward from the device in a third direction that is different from the second direction;
- and
- a cover disposed over at least a portion of the housing, the cover visually concealing the first loudspeaker, the second loudspeaker, and the third loudspeaker.

A device comprising:
- a first loudspeaker oriented to emit first sound outwards from the device in a first direction;
- a second loudspeaker oriented to emit second sound outwards from the device in a second direction that is different from the first direction;
- a third loudspeaker oriented to emit third sound outwards from the device in a third direction that is different than the second direction;
- a unitary housing having an interior surface, wherein the unitary housing includes:
- one or more first sidewalls that extend from the interior surface to at least partially form a first back volume for the first loudspeaker, the first back volume having a first size,
- one or more second sidewalls that extend from the interior surface to at least partially form a second back volume for the second loudspeaker separate from the first back volume, the second back volume having a second size different than the first size, and
- one or more third sidewalls that extend from the interior surface to at least partially form a third back volume for the third loudspeaker separate from the second back volume, the third back volume having a third size different than the second size;
- and
- a seal coupled to the unitary housing, the seal at least partially enclosing the first back volume, the second back volume, and the third back volume at a first location that is spaced apart from a second location at which the one or more first sidewalls, the one or more second sidewalls, and the one or more third sidewalls extend from the interior surface.
