Smart Speaker System Adapts Sound Based on Speaker Placement

This patent describes an audio system that intelligently chooses how to play different parts of a sound through different speakers, adapting its method based on where each speaker is placed in a room.

What it covers

The patent describes an audio processing system that receives sound information, including separate sound parts (audio components) and data about where your speakers (audio transducers) are located. A "renderer circuit" then creates the actual sound signals for these speakers. Crucially, a "render controller circuit" picks different ways to play the sound (rendering modes, like stereo or 3D audio) for different speakers or even different sound parts. For example, if one speaker is out of place compared to its ideal spot, the system might use a different rendering mode for that speaker or a group of speakers to make the sound still feel right, as described in claim 1 and 4. It can also adjust based on the type of sound, like speech versus music.

What it doesn't cover

• —Systems that only use a single rendering mode for all speakers and all audio components, without adaptation.
• —Audio systems that do not consider the actual physical position of the speakers when choosing how to render sound.
• —Systems that cannot apply different rendering modes to different *subsets* of speakers simultaneously.
• —Systems that cannot apply different rendering modes to different *audio components* (e.g., a voice track vs. background music).
• —Basic stereo or surround sound systems that do not dynamically adapt rendering based on speaker position deviations.

The clever bit

The novelty lies in dynamically selecting different rendering modes for *subsets* of speakers or even individual *audio components*, based on the actual physical location of the speakers relative to ideal positions. This allows the system to compensate for imperfect setups.

Why it matters

This technology aims to improve the listening experience in real-world setups where speakers might not be perfectly positioned. It allows for more flexible and adaptive audio systems, potentially making advanced audio formats like immersive sound more accessible and enjoyable in various home environments. This could be important for consumer electronics companies developing next-generation soundbars, home theater systems, and smart speakers.

• 2.Soundbars with spatial audio capabilities
• 3.Smart speakers with adaptive sound features
• 4.Immersive audio systems (e.g., Dolby Atmos, DTS:X)
