Problems solved by technology

Even though such speakers may be capable of playing back multi-channel audio content (such as 5.1 surround sound), they are limited in sound dispersion and playback separation so that it is always apparent that the sound is coming from a single small speaker source in the center of the room

Embodiment Construction

[0019] Systems and methods are described for a speaker in a standalone system or smart speaker unit that creates an expansive audio pattern for playback of multi-channel audio content. Aspects of one or more embodiments described herein may be implemented in or used in conjunction with an audio or audio-visual (AV) system that processes one or more processes including the execution of software instructions. Mixing, presentation and playback of source audio information in a computer or processing device.

[0020] Any of the described embodiments may be used alone or in any combination with each other. While the various embodiments may have been motivated by the various deficiencies of the prior art which may be discussed or mentioned in passing at one or more places in this specification, the embodiments do not necessarily address these deficiencies any of. In other words, different embodiments may address different deficiencies that may be discussed in this specification. S...

Abstract

Embodiments are directed to a speaker system that contains an array of multiple dispersion drivers that creates an expansive acoustic pattern to playback multi-channel audio content through a standalone speaker. The speaker system comprises an interface receiving stereo audio; an upmixer generating surround sound formatted audio from the stereo audio including one or more height channels; a virtualizer / downmixer component coupled to the upmixer and generating speaker feeds for two or more loudspeaker output sections, configured to play back the stereo audio, wherein each output section is further configured to play its own dedicated stereo audio signals; and a set of drivers each coupled to a respective output section and configured to project sound in at least two different dispersion patterns.

Description

technical field [0001] One or more implementations relate generally to stereo speaker systems, and more particularly to stand-alone speakers with multiple dispersed drivers. Background technique [0002] The advent of smart speaker technology has greatly increased the use of single, small or portable speakers centrally placed in the home or office. Smart speakers are often embodied in wireless speaker boxes that provide interactive functionality to allow users to use voice commands to access and control various functions, such as home entertainment, appliance control, and information functions. For example, such speakers can provide the main user interface for certain "smart home" devices that allow the user to speak commands to set security / lighting / heating controls, play TV or music content, give answers, provide news Or encyclopedia information and so on. Thus, smart speakers can be integrated into home automation systems that provide compatibility across several servic...
