An electronic furniture assembly of the present invention includes: (i) a furniture assembly comprising: (A) a base (e.g., a seat portion), (B) at least one transverse or upright member (e.g., a side, armrest or backrest), and (ii) a speaker system mounted within one or more portions of the furniture assembly. A method of tuning a speaker of an audio-enhanced furniture system includes presenting a user with predetermined tuning profiles corresponding to a plurality of configuration footprint shapes in which the furniture assembly can be assembled and in response to a user selection of a given configuration footprint shape, tuning the speaker system according to the tuning profile selected by the user.

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.

The patent application discloses a personal audio entertainment system, which comprises five major parts: entertainment play equipment, Bluetooth transmitter, gaming chair with audio play devices, Bluetooth receiver with charging function, and audio play equipment with a subwoofer and a Bluetooth receiver integrated in the main speaker. The top of the Bluetooth audio gaming chair is connected with a neck pillow, one end of the neck pillow is fixedly connected with a lace, and one end of the lace is connected with a plug buckle, one end of the gaming chair is provided with a backrest, the bottom end of the backrest is connected with a cushion, the bottom end of the cushion is rotatably connected with a bracket, the bottom end of the bracket is connected with rollers, and one end of the gaming chair is connected with audio play devices; The audio play devices comprise speakers, wire, and a Bluetooth receiver, and the Bluetooth receiver and the speakers are connected by wire; The audio play equipment is composed of a main speaker, a sub-speaker, a subwoofer, wire and a Bluetooth receiver, and the Bluetooth receiver is integrated in the main speaker. The personal audio entertainment system connects the entertainment play equipment with Bluetooth audio gaming chair and Bluetooth audio using Bluetooth transmitter, and have 4-channel stereo surround sound including front left sound, front right sound, rear left sound, and rear right sound. The personal audio entertainment system is highly efficient and convenient. There is no need to put independent speakers in the back of the chair to take up moving space.

A chair system including a main unit and an untethered chair is provided. The main unit includes a wireless transmitter, a subwoofer, an audio stream receiver and a processor. The untethered chair includes a plurality of speakers, a power source and a wireless receiver for receiving a processed audio stream from the main unit.

An electronic furniture assembly of the present invention includes: (i) a furniture assembly comprising: (A) a base (e.g., a seat portion), (B) at least one transverse or upright member (e.g., a side, armrest or backrest), and (ii) a speaker system mounted within one or more portions of the furniture assembly. A method of tuning a speaker of an audio-enhanced furniture system includes presenting a user with predetermined tuning profiles corresponding to a plurality of configuration footprint shapes in which the furniture assembly can be assembled and in response to a user selection of a given configuration footprint shape, tuning the speaker system according to the tuning profile selected by the user.

An audio-enhanced furniture system comprises: a furniture assembly having a partially acoustically transparent material, such as an upholstery fabric or a perforated, rigid structure that is perforated in order to be more acoustically transparent; and a speaker system positioned within the furniture assembly, the speaker system including a speaker covered by the partially acoustically transparent material. The speaker is configured to be tuned to compensate for sound being emitted from the speaker through the perforated partially acoustically transparent material.

Modular equipment includes a main module that has a main speaker, main communication components arranged to implement at least one wireless communication, power supply components arranged to acquire main power supply from the mains, main assembly means arranged to assemble the main module with one or more additional modules, a processor component arranged to detect if the main module is assembled with a first additional module comprising one or more microphones and, if this is the case, to activate at least one additional function implemented by the equipment and using the microphone(s).

An IP speaker system is disclosed that includes an IP speaker connected to one or more external analog speakers. The IP speaker comprises a CPU that provides an audio data stream for transmission to a first amplifier and a second amplifier. The first amplifier outputs a first analog audio signal at a first power level for driving an internal driver of the IP speaker, and the second amplifier outputs a second analog audio signal at a second power level for driving one or more external drivers of the one or more external analog speakers. The CPU supervises the one or more external analog speakers so as to detect any speaker failure, disconnection, short or other change in operational status. The IP speaker also comprises a power circuit that receives electrical power transmitted over a network cable as its input power and provides output power available for consumption by the IP speaker and the one or more external analog speakers. The power circuit measures the input power and decreases the output power if the measured input power exceeds a predetermined power level.

A chair system including a main unit and an untethered chair is provided. The main unit includes a wireless transmitter, a subwoofer, an audio stream receiver and a processor. The untethered chair includes a plurality of speakers, a power source and a wireless receiver for receiving a processed audio stream from the main unit.
