Abstract

A method of playing back audio content with improved immersiveness can include receiving, at a playback device, audio input including vertical content having a high-frequency portion and a low-frequency portion. The playback device can face along a first sound axis and comprise an up-firing transducer configured to direct sound along a second sound axis that is vertically angled with respect to the primary sound axis and a side-firing transducer or array configured to direct sound along a third axis that is horizontally angled with respect to the first sound axis. The low-frequency portion of the vertical content can be played back via the side-firing transducer or array, while the high-frequency portion of the vertical content can be played back via the up-firing transducer.

Claims (67)

1 . A first playback device comprising:

a transducer orientated in a direction away from a target location;

one or more processors; and

a tangible, non-transitory computer-readable medium storing instructions that, when executed by the one or more processors, cause the first playback device to perform operations comprising:

receiving audio content;

generating, based on the received audio content, first audio data and second audio data, wherein the first audio data comprises a first frequency portion and a second frequency portion, and wherein the second audio data comprises a first frequency portion and a second frequency portion;

determining, based on the target location, a first delay and a second delay;

outputting, via the transducer, the second frequency portion of the first audio data according to the first delay; and

causing, via a second playback device, playback of (i) the first frequency portion of the first audio data according to the second delay, and (ii) the first frequency portion and the second frequency portion of the second audio data.

2 . The first playback device of claim 1 , further comprising one or more microphones, and wherein the operations further comprise:

receiving microphone data from the one or more microphones;

analyzing the microphone data to determine acoustic characteristics of an environment in which the first playback device is positioned; and

dynamically adjusting at least one of: (i) the first delay or the second delay, or (ii) a frequency distribution between the first frequency portion and the second frequency portion of the first audio data, based on the determined acoustic characteristics.

3 . The first playback device of claim 2 , wherein the analyzing comprises:

detecting test tones output by the second playback device via the microphone data; and

determining a position of the second playback device relative to the first playback device based on the detected test tones.

4 . The first playback device of claim 1 , wherein the first playback device comprises a display device having the transducer built in, and wherein the operations further comprise:

outputting the first frequency portion of the first audio data via the built-in transducer of the display device; and

wirelessly transmitting control signals to the second playback device to coordinate the playback of the first frequency portion of the first audio data and the first frequency portion and the second frequency portion of the second audio data.

5 . The first playback device of claim 1 , wherein the first playback device comprises a soundbar device configured for positioning adjacent to a display device.

6 . The first playback device of claim 1 , wherein determining the first delay and the second delay comprises:

calculating a first path length for the second frequency portion of the first audio data output from the transducer to reach the target location;

calculating a second path length for the first frequency portion of the first audio data output from the second playback device to reach the target location; and

determining the first delay and the second delay based on a difference between the first path length and the second path length.

7 . The first playback device of claim 6 , wherein the first path length includes reflection off a first acoustic surface, and the second path length includes reflection off a second acoustic surface different from the first acoustic surface.

8 . A method performed by a first playback device having a transducer orientated in a direction away from a target location, the method comprising:

receiving audio content;

determining, based on the target location, a first delay and a second delay;

outputting, via the transducer, the second frequency portion of the first audio data according to the first delay; and

9 . The method of claim 8 , wherein the first playback device further comprises one or more microphones, and wherein the method further comprises:

receiving microphone data from the one or more microphones;

analyzing the microphone data to determine acoustic characteristics of an environment in which the first playback device is positioned; and

10 . The method of claim 9 , wherein the analyzing comprises:

detecting test tones output by the second playback device via the microphone data; and

determining a position of the second playback device relative to the first playback device based on the detected test tones.

11 . The method of claim 8 , wherein the first playback device comprises a display device having the transducer built in, and wherein the method further comprises:

outputting the first frequency portion of the first audio data via the built-in transducer of the display device; and

12 . The method of claim 8 , wherein the first playback device comprises a soundbar device configured for positioning adjacent to a display device.

13 . The method of claim 8 , wherein determining the first delay and the second delay comprises:

calculating a first path length for the second frequency portion of the first audio data output from the transducer to reach the target location;

calculating a second path length for the first frequency portion of the first audio data output from the second playback device to reach the target location; and

determining the first delay and the second delay based on a difference between the first path length and the second path length.

14 . The method of claim 13 , wherein the first path length includes reflection off a first acoustic surface, and the second path length includes reflection off a second acoustic surface different from the first acoustic surface.

15 . A tangible, non-transitory computer-readable medium storing instructions that, when executed by one or more processors of a first playback device having a transducer orientated in a direction away from a target location, cause the first playback device to perform operations comprising:

receiving audio content;

determining, based on the target location, a first delay and a second delay;

outputting, via the transducer, the second frequency portion of the first audio data according to the first delay; and

16 . The tangible, non-transitory computer-readable medium of claim 15 , wherein the first playback device further comprises one or more microphones, and wherein the operations further comprise:

receiving microphone data from the one or more microphones; analyzing the microphone data to determine acoustic characteristics of an environment in which the first playback device is positioned; and

17 . The tangible, non-transitory computer-readable medium of claim 16 , wherein the analyzing comprises:

detecting test tones output by the second playback device via the microphone data; and

determining a position of the second playback device relative to the first playback device based on the detected test tones.

18 . The tangible, non-transitory computer-readable medium of claim 15 , wherein the first playback device comprises a display device having the transducer built in, and wherein the operations further comprise:

outputting the first frequency portion of the first audio data via the built-in transducer of the display device; and

19 . The tangible, non-transitory computer-readable medium of claim 15 , wherein the first playback device comprises a soundbar device configured for positioning adjacent to a display device.

20 . The tangible, non-transitory computer-readable medium of claim 15 , wherein determining the first delay and the second delay comprises:

calculating a first path length for the second frequency portion of the first audio data output from the transducer to reach the target location;

calculating a second path length for the first frequency portion of the first audio data output from the second playback device to reach the target location; and

determining the first delay and the second delay based on a difference between the first path length and the second path length.
