A seat integrating a loudspeaker system includes a seat having a seat body with a horizontally oriented seat bottom and a seat back secured thereto. The seat back includes an upper end and a lower end, wherein the lower end is positioned adjacent the seat bottom. The loudspeaker system includes a sound assembly mounted within the seat for selective movement between a storage orientation in which the sound assembly is housed and hidden within a support housing mounted along the seat and a use orientation extending from the support housing in which the sound assembly is positioned for use.

The disclosure relates to an audio signal processing apparatus for processing an input audio signal, comprising a filter unit comprising a plurality of filters, each filter configured to filter the input audio signal to obtain a plurality of filtered audio signals, each filter designed according to an extended mode matching beamforming applied to a surface of a half revolution, the surface partially characterizing a loudspeaker enclosure shape, a plurality of scaling units, each scaling unit configured to scale the plurality of filtered audio signals using a plurality of gain coefficients to obtain a plurality of scaled filtered audio signals, and a plurality of adders, each adder configured to combine the plurality of scaled filtered audio signals, thereby providing an output audio signal for producing a sound field having a beam directivity pattern defined by the plurality of gain coefficients.

Systems and methods for providing augmented arrays for audio playback are disclosed. An example playback device includes a first transducer configured to output audio along a first acoustic axis and a second transducer configured to output audio along a second acoustic axis. The playback device is configured to receive a source stream of audio content including at least a first input channel and a second input channel. The device plays back first audio output via the first transducer based on the first input channel and directed along the first acoustic axis, and plays back second audio output via the second transducer based on the second input channel and directed along the second acoustic axis, wherein the second audio output at least partially cancels the first audio output along a first spatial region offset from the first acoustic axis.

A system for facilitating configuration of an audio system tests the existing audio system configuration by playing reference audio clips of various different genres of programming, the audio of which is received by a microphone of a remote control device or other handheld mobile device at various different listening points in the room. The system then compares the audio signal representing audio of the reference audio clip received at the microphone to a reference audio signal representing the reference audio clip and determines other audio characteristics. The system then determines, based on the comparison and other characteristics of the room (e.g., furniture layout, room construction materials, wall treatments and current speaker positioning) suggested changes to a configuration of the audio system to increase audio quality of the audio system for playing audio associated with the various different genres of programming.

Low-latency audio networking is disclosed. In one embodiment, an example playback device includes a processor and memory having stored thereon instructions executable by the processor. The example instructions are to cause the first playback device to perform functions comprising: receiving audio information; selecting a first frequency channel of a first spectrum based on a threshold latency associated with the audio information; transmitting to the second playback device via a second frequency channel of a second spectrum, control information that identifies the first frequency channel of the first spectrum; and transmitting to the second playback device via the first frequency channel of the first spectrum, the audio information to be played by the second playback device.

The aspects disclosed herein are related to providing a stereoscopic audio environment that is based on speaker position and/or orientation. Once the speaker (or groups of speakers) are identified by the above-described techniques, the audio signal uniquely delivered to each of the speakers may be customized to produce an optimal sound environment.

A loudspeaker includes a first sound box, a second sound box, and a connection shaft. The first sound box includes at least one first speaker unit. The second sound box includes at least one second speaker unit. The connection shaft includes a cylinder, at least one first guide ring, and at least one second guide ring. The first guide ring is electrically sleeved on the cylinder and connected to the first speaker unit. The second guide ring is electrically connected to the second speaker unit. The first guide ring and the second guide ring correspond to each other and are electrically connected to each other, so that the first sound box and the second sound box are electrically connected to each other. The first sound box may rotate freely, about the connection shaft, with respect to the second sound box.

Apparatus for supplying sound with first and second loudspeakers including: a control signal generator for generating a first control signal for the first loudspeaker and a second control signal for the second loudspeaker. The control signal generator includes: a mix signal generator stage generating a first mix signal for the first control signal and a second mix signal for the second control signal from a first channel signal or a second channel signal such that the first mix signal and the second mix signal have a phase difference; a mixer stage for mixing the first channel signal with the first mix signal to obtain the first control signal, and for mixing the second channel signal with the second mix signal to obtain the second control signal; and an interface for transmitting the first control signal to the first loudspeaker and for transmitting the second control signal to the second loudspeaker.

Methods and systems are provided for audio devices with enhanced directional operations. A user of an audio system may be prompted to provide an audio input. Once received, the audio input may be processed, and based on processing of the audio input positioning related information associated with the user may be generated. Outputting of an audio output in the audio system may then be controlled based on the positioning related information. Controlling the outputting of the audio output may include configuring at least one audio output related parameter or function for optimizing directionality of the audio output based on the positioning related information.
