Playback Zone Grouping Through Direct Speaker Interface Control

Solution Overview

Problem

Existing media playback systems with multiple devices often require inefficient control methods, such as using a separate control device for zone management, which can be cumbersome and less efficient.

Innovation Solution

Playback devices can be controlled directly through their own control interfaces or bonded controllers, allowing them to form zones and play media in synchrony with other devices based on detected inputs, without needing a separate control device for multiple devices.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If external control devices are used to manage multiple playback zones, then zone management capability is provided, but device complexity and operational efficiency deteriorate

Engineering Contradiction:

Improvezone management capabilityVSAvoidsystem complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The playback device autonomously performs zone management functions by detecting inputs at its own control interface. The device can independently form zones with other playback devices and initiate synchronized playback without requiring external control devices, thereby eliminating the need for separate controllers and reducing overall system complexity.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The playback device integrates multiple functions including media playback, zone formation, and zone management capabilities within a single device. The control interface on the playback device serves both for basic playback control and for managing zone configurations, consolidating what would traditionally require separate control device functionality into the playback device itself.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Adaptability or versatility

If external control devices are used to manage multiple playback zones, then zone management capability is provided, but ease of operation deteriorates

Engineering Contradiction:

Improvezone management capabilityVSAvoidoperational efficiency

Core Design Contradiction:

Adaptability or versatilityVSEase of operation

Solution Approach 1:

The playback device autonomously performs zone management functions by detecting inputs at its own control interface. The device can independently form zones with other playback devices and initiate synchronized playback without requiring external control devices, thereby eliminating the need for separate controllers and reducing overall system complexity.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The patent combines the control functions and playback functions into a single integrated system. The control interface on the playback device merges zone management capabilities with media playback control, allowing users to manage zones directly from the device itself rather than requiring a separate control device, thus simplifying the operational workflow.

Inventive Principle:

Principle #5Merging (Combining)

3Productivity

If control interface is implemented on playback device, then operational efficiency improves, but device complexity increases

Engineering Contradiction:

AI summary

An example method includes detecting, via a control interface of a first playback device while at least one second playback device is playing media, an input indicating a command for the first playback device to (i) form a zone with the second playback device and (ii) play back the media in synchrony, and based on the detected input, causing the first playback device to carry out the command. A second example method includes detecting, by a control device while at least one first playback device is playing media, an input indicating a command for a second playback device to (i) form a zone with the first playback device and (ii) play back the media in synchrony, wherein the control device is configured to transmit commands to the second playback device; and based on the detected input, causing the second playback device to carry out the command.
