An electronic apparatus is provided. The electronic apparatus includes a communication interface; a display; an internal speaker; and a processor configured to control the internal speaker to generate a first audio signal and control the communication interface to transmit a signal to control an external audio device to generate a second audio signal that is synchronized with the first audio signal. The processor is configured to: obtain a first processing time regarding the first audio signal and a second processing time regarding the second audio signal; and control the internal speaker and the communication interface based on the first processing time and the second processing time so that a difference between a first output timing of the first audio signal and a second output timing of the second audio signal is less than a predetermined value.

To enable multichannel audio data to be transmitted favorably. Multichannel audio data of a predetermined number of channels is acquired. The multichannel audio data has a sampling frequency corresponding to the predetermined number of channels. Audio data of the respective channels configuring the multichannel audio data are sequentially transmitted to a reception side via a predetermined transmission channel for each unit audio data. Information indicating the sampling frequency is added to the transmission audio data.

A speaker for transmitting reflected sound waves off an upper surface down to a listening environment, comprising: a cabinet containing a plurality of audio drivers, direct-firing drivers within the cabinet oriented to transmit sound along a horizontal axis substantially perpendicular to a front surface of the cabinet, and a pair of upward-firing slotted drivers placed proximate to ends of an top surface of the cabinet and oriented at an inclination angle relative to the horizontal axis. The slotted drivers are configured to create an overlapping reflected sound projection for high frequency sound when reflected down to a listening position located at a distance in front of the speaker pair. Such a speaker projects reflected sound that provides wider horizontal or side-to-side dispersion to better cover the listening area.

The present invention discloses an endpoint mixing product having a control module and a speaker system. The speaker system includes speakers in which each speaker is with a 3D coordinate. The speakers communicate with the control module respectively. The control module is configured to deliver sound fragments to the speakers. The sound fragments contain 3D coordinates and correspond to the speakers respectively through the 3D coordinates. The speakers are configured to receive and play the corresponding sound fragments respectively to form an endpoint mixing sound.

An acoustic device including a first passive radiator structure and a second passive radiator structure is provided. The first passive radiator structure includes a passive diaphragm mechanically coupled to a first enclosure member via a first flexible suspension element, and is configured to vibrate relative to the first enclosure member. The second passive radiator structure includes a second enclosure member, and is configured to vibrate relative to the first enclosure member. The second passive radiator structure further includes a second flexible suspension element mechanically coupled to the first enclosure member and the second enclosure member. The second passive radiator structure further includes an active electro-acoustic transducer mechanically coupled to the second enclosure member. The second passive radiator structure moves when the active electro-acoustic transducer vibrates. A first mass of the first passive radiator structure is less than a second mass of the second passive radiator structure. During operation, the first enclosure member experiences substantially no vibrations.

A speaker system is provided having a primary speaker module configured to communicate with an external audio device and having a speaker output face and a back surface, and a secondary speaker module in signal communication with the primary speaker module and having a speaker output face and a back surface. The primary speaker module and the secondary speaker module combine in at least two configurations, a first configuration in which the primary speaker module and the secondary speaker module are connected at their back surfaces and their respective speaker output faces face opposite directions, and a second configuration in which the primary speaker module and the secondary speaker module are side by side and their respective speaker output faces face substantially the same direction.

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.

Disclosed herein are system, apparatus, article of manufacture, method and/or computer program product embodiments, and/or combinations and sub-combinations thereof, for identifying audio characteristics of a room using a spread code. In some embodiments, a first electronic device receives a spread spectrum signal from a second electronic device over an audio data channel. The first electronic device determines a time of receipt of the spread spectrum signal based on despreading. The first electronic device calculates an airtime delay based on the time of receipt and a time of transmission of the spread spectrum signal. The first electronic device determines a direction of the second electronic device based on the spread spectrum signal and beam forming techniques. The first electronic device adjusts playback of audiovisual content at the second electronic device and a third electronic device for a location based on the airtime delay and the direction.

The present subject matter provides a technical solution to the technical problems facing sound localization by separating sounds and reproducing the separated sounds using a set of loudspeakers and a set of headphones. A general soundtrack that is meant to be experienced throughout the room would play through the loudspeakers, and specific sounds that are meant to be experienced near the listener would be played through a binaural representation in the headphones. The headphones may be selected to avoid occluding the ear, allowing sound produced at the loudspeakers to be heard clearly. This separation and reproduction of sounds using a combination of a loudspeaker and headphone provides a technical solution to the technical problem facing typical surround sound systems by localizing sounds for listeners in any location within a room. This improves reproduction accuracy of location-specific audio objects, including audio objects above or below a coplanar speaker configuration.

A noise cancelling soundbar that may be integrated into a piece of furniture, such as a bed, comprising one or more loudspeakers, an integrated power amplifier, one or more microphones, an audio input communication module, and an active noise cancellation module. After receiving an audio input signal from a media source, such as a TV or smartphone, the noise cancelling soundbar may produce an amplified output signal. By using its microphones and active noise cancellation technology, the noise cancelling soundbar may, in addition to reproducing input audio via its loudspeakers, generate negative sound waves which destructively interfere with ambient noise to allow users to listen to audiovisual media without disturbing non-listeners in the area, and without using headphones.
