Audio playback equipment includes microphones, a loudspeaker, emitter means arranged to emit a sound detection signal, and at least one processor component arranged: to acquire detection audio signals produced by the microphones as a result of picking up the detection sound signal; from the audio detection signals, to detect a run of maskings in which at least two distinct microphones are masked in succession; to analyze a detected run of maskings so as to detect a command slide made by a user on the housing via at least two distinct microphones; and to cause at least one predetermined action to take place as a result of detecting said command slide.

A display device including a display configured to display image content; a wireless communication interface configured to wirelessly connect with a plurality of external speakers spaced a distance from the display; at least one positioning module configured to obtain position information of the plurality of external speakers identifying a spatial relationship between each external speaker and the display; and a controller configured to transmit an audio signal to be output by the external speakers, based on the obtained position information of the external speakers.

Methods and systems are provided for audio devices with enhanced directional operations. An example system may include one or more audio output components; one or more sensors configured to generate sensory data relating to a user; and one or more control circuits configured to control the one or more audio output components based on positioning information associated with positioning of the user. The positioning information may be generated or adjusted based on the sensory data, and the controlling may include providing a three-dimensional audio environment according to the user.

Equipment including a casing wherein are located: a box; a first loudspeaker disposed inside the box, the first loudspeaker being arranged to broadcast sounds outwards from the casing; a main electronic board placed in the casing outside of the box and on which is mounted, at least one power supply module producing a first power supply voltage; a connecting device passing through the wall of the box; a secondary electronic board inside the box on which is mounted, at least one first amplifier connected to the first loudspeaker, the secondary electronic board being connected to the main electronic board via the connecting device to power the first amplifier with the first voltage.

An apparatus and method of rendering audio. A binaural signal is split on an amplitude weighting basis into a front binaural signal and a rear binaural signal, based on perceived position information of the audio. In this manner, the front-back differentiation of the binaural signal is improved.

Various implementations include audio systems and methods for mixed rendering to enhance audio output. Certain implementations include an audio system having: at least one far-field speaker configured to output a first portion of an audio signal; and a pair of non-occluding near-field speakers configured to output a second portion of the audio signal in synchrony with the output of the first portion of the audio signal, where the second portion of the audio signal increases intelligibility of the speech content within the audio signal.

Example techniques relate to audio generation in a media playback system. Based on one or more first functions and first characteristics of an area, the system may generate first audio that includes a first audio signal and a second audio signal. The system provides the first audio signal to at least one first audio driver and the second audio signal to at least one second audio driver, thereby causing a first playback device and a second playback device to play back the first audio synchronously. The system receives second characteristics of the area and based on one or more second functions and the second characteristics, generates second audio comprising a third audio signal and a fourth audio signal. The system provides the third audio signal to the at least one first audio driver and the fourth audio signal to the at least one second audio driver.

A system for guiding a user, comprising a portable computer terminal and a stereophonic audio device that is associated with the head of the user, the terminal and the device communicating with each other wirelessly. The audio device is equipped with inertial sensors and with a binaural rendering engine. The portable computer terminal comprises software that generates guiding-instruction data associating a description of an audio signal to be delivered, and an indication relative to the virtual position of this audio signal. The binaural rendering engine generates a spatialized audio signal, which is delivered to the user by the audio device, depending on the guiding-instruction data, transmitted by the portable computer terminal via wireless communication, and on data of the inertial sensors.

Two speaker units are arranged on the right side from the center of a seat; two speaker units are arranged on the left side from the center of the seat; one of the two speaker units arranged on the right side is arranged at a position closer to the right ear of a user seated on the seat as compared with the other one of the two speaker units arranged on the right side; one of the two speaker units arranged on the left side is arranged at a position closer to the left ear of the user seated on the seat as compared with the other one of the two speaker units arranged on the left side; acoustic signals obtained on the basis of a reproduction target are emitted from the two speaker units arranged on the right side to be opposite in phase to each other; the acoustic signals obtained on the basis of the reproduction target are emitted from the two speaker units arranged on the left side to be opposite in phase to each other; and the acoustic signals are emitted from two speaker units arranged on the positions closer to the ears not to be opposite in phase to each other.

The present disclosure relates to a method and system for calibrating a loudspeaker system in an environment (1). The loudspeaker system comprises an audio device (10) with a first and second loudspeaker arranged with a predetermined horizontal separation. The method comprises the steps of emitting (S2a, S2b) a first and second calibration audio signal from the first and second loudspeaker (11) of the audio device (10), wherein the second calibration audio signal is distinguishable from the first calibration audio signal. The method further comprises receiving (S3a, S3b), with a first external microphone (20) the first and second calibration audio signal, determining (S4) the position of the first external microphone (20) relative to the audio device (10) and calibrating (S8) the loudspeaker system based on the determined position of the first external microphone (20).
