Abstract: An example method is performed by a media playback system comprising a plurality of audio drivers having a first radiation pattern. The method includes receiving data representing audio content, where each datum of the data indicates (i) a frequency and (ii) an amplitude corresponding to the frequency. The method further includes, for each audio driver of the plurality of audio drivers, determining a transfer function; processing each datum of the data based on (i) the frequency indicated by the given datum and (ii) the determined transfer function; and providing, to the given audio driver, a respective signal representing the data processed for the given audio driver, thereby causing the plurality of audio drivers to play back the audio content according to a second radiation pattern that is different from the first radiation pattern. An example media playback system and an example non-transitory computer-readable medium related to the example method is also disclosed herein.

Abstract: This disclosure relates to speakers and more specifically to an array speaker for distributing music uniformly across a room. A number of audio drivers can be radially distributed within a speaker housing so that an output of the drivers is distributed evenly throughout the room. In some embodiments, the exit geometry of the audio drivers can be configured to bounce off a surface supporting the array speaker to improve the distribution of music throughout the room. The array speaker can include a number of vibration isolation elements distributed within a housing of the array speaker. The vibration isolation elements can be configured reduce the strength of forces generated by a subwoofer of the array speaker.

Abstract: At least two closely spaced identical or similar loudspeaker assemblies, each loudspeaker assembly comprising at least two identical or similar loudspeakers pointing in different directions so that the loudspeaker assemblies have adjustable, controllable or steerable directivity characteristics. For example, a control module may drive adjust, control or steer the loudspeaker assemblies so that at least one acoustic wave field is generated at least at one listening position.
