A multi-channel audio playback system includes a front speaker, a wearable speaker, and a signal processor. The front speaker is configured to receive front sound field signals (FS). The wearable speaker is designed to allow a listener to hear environmental sounds and is configured to receive rear sound field signals (RS). The signal processor is configured to divide a multi-channel signal into a front sound field signal group (FSG) and a rear sound field signal group (RSG); mix FSG (RSG) and generate the FS (RS), wherein the number of the FS (RS) is equal to the number of the drivers of the front speaker (wearable speaker); and perform time delay adjustment on FS or RS, so that a difference between times for sound waves emitted by the front speaker and by the wearable speaker to respectively reach ears of the listener is less than a default value.

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.

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.

The present disclosure relates to loudspeaker devices and configurations. In at least one embodiment, a loudspeaker includes a housing structure having a multi-sided cross-sectional profile, a first speaker configuration coupled to a first face of the housing structure, and a second speaker configuration coupled to a second face of the housing structure. The first face of the housing structure and the second face of the housing structure may be adjacent to each other, and the first face of the housing structure and the second face of the housing structure may be substantially planar, in one or more examples. The loudspeaker may further comprise a controller configured to rotate the housing structure. For example, the housing structure may be rotated about a central axis of the housing structure. Further, the housing may be an elongated triangular structure in at least one example.

A headphone speaker system includes over-the-ear speakers (left and right) and inner-ear speakers (left and right). The left over-the-ear speaker and the right over-the-ear speaker are configured to receive a left surround audio channel of an audio signal and a right surround audio channel of the audio signal, respectively, from a surround sound processor, and are configured to be positioned outside a left ear canal of a user and outside a right ear canal of the user, respectively. The left inner-ear speaker and the right inner-ear speaker are configured to receive a left front audio channel of the audio signal and a right front audio channel of the audio signal, respectively, from the surround sound processor, and are configured to be positioned at least partially within the left ear canal of the user and at least partially within the right ear canal of the user, respectively.

The present invention presents an audio triangular system based in the structure of panning in the stereophonic mix, said audio triangular system uses 2 input audio channels and 3 output mono audio playback systems, also creates an assignment of panning values to obtain the audio signals corresponding to each one of the three mono audio playback systems, it is important to mention that the interaction of the audio signals obtained from the previous assignment of values causes the triangular effect of the present invention, additionally, the previously mentioned 3 mono audio playback systems must be capable of reproduce a full frequency range of treble, mid and bass tones each one, furthermore, said mono audio playback systems should be located at a certain distance and angles from each other and in relation to the listener.

This application provides a method and an apparatus for determining a virtual speaker set. The method for determining a virtual speaker set includes: determining a target virtual speaker from F preset virtual speakers based on a to-be-processed audio signal, where each of the F virtual speakers corresponds to S virtual speakers, F is a positive integer, and S is a positive integer greater than 1; and obtaining, from a preset virtual speaker distribution table, respective position information of S virtual speakers corresponding to the target virtual speaker, where the virtual speaker distribution table includes position information of K virtual speakers, the position information includes an elevation angle index and an azimuth angle index, K is a positive integer greater than 1, FK, and FSK. This application can improve audio signal playback effect.

Provided is a system including at least two robots. A first robot includes a chassis, a set of wheels, a wheel suspension, sensors, a processor, and a machine-readable medium for storing instructions. A camera of the first robot captures images of an environment from which the processor generates or updates a map of the environment and determines a location of items within the environment. The processor extracts features of the environment from the images and determines a location of the first robot. The processor transmits information to a processor of a second robot and determines an action of the first robot and the second robot. A smart phone application is paired with at least the first robot and is configured to receive at least one user input specifying an instruction for at least the first robot and at least one user preference.

To enable channel setting to be performed easily and accurately to speakers. Thus, provided is a speaker system including: N number of speakers, the N being three or more; and a signal processing device capable of communicating with each speaker. The signal processing device performs processing of recognizing two arrangement reference speakers with reception of notification that a designation operation has been received from a user, from two speakers among the N number of speakers, and processing of acquiring distance information between each speaker. The signal processing device recognizes a relative-position relationship between the N number of speakers, with the two arrangement reference speakers and the distance information between each speaker. Then, the signal processing device automatically sets a channel to each speaker, on the basis of the relative-position relationship recognized.
