Multi-Speaker Volume Offset Control Within Speaker Limits
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems struggle to maintain consistent volume levels across multiple speakers of different manufacturers and models, and adjust volumes within their operational ranges while preserving relative offsets, leading to potential over or under-adjustment.
Innovation Solution
A system that calculates provisional volume levels by summing selected volume levels with speaker-specific offsets, ensuring these levels fall within the operational range of each speaker, and adjusts accordingly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a single volume controller adjusts all speakers simultaneously, then volume adjustment is simple and fast, but it cannot account for different speaker operational ranges and manufacturers, leading to over or under-adjustment
Solution Approach 1:
The patent divides the volume control system into speaker-specific segments, where each speaker has its own operational range parameters and offset settings. The volume controller processes each speaker individually based on its characteristics rather than applying a uniform adjustment to all speakers simultaneously.
Solution Approach 2:
The patent applies local quality by allowing each speaker to have customized volume offsets and operational range settings specific to its manufacturer and model. This enables tailored volume adjustments for each speaker location and type while maintaining overall system coordination through the controller.
2Reliability
If volume offsets are applied to maintain consistent volume relationships, then relative volume balance is improved, but speakers may exceed their operational ranges causing distortion or damage
Solution Approach 1:
The patent implements feedback by continuously monitoring each speaker's operational range and adjusting volume offsets accordingly. The system receives feedback about each speaker's capabilities and constraints, then dynamically adjusts the volume distribution to maintain consistent relationships without exceeding individual speaker limits.
Solution Approach 2:
The patent applies dynamics by making volume offsets adjustable and adaptive rather than fixed. The system can dynamically modify the volume distribution among speakers based on real-time conditions, speaker characteristics, and operational constraints, allowing flexible maintenance of volume relationships.
3Adaptability or versatility
If different volume levels are set for each speaker individually, then speaker-specific optimization is achieved, but system complexity and control difficulty increase
Solution Approach 1:
The patent applies universality by creating a centralized volume controller that handles multiple functions: it manages individual speaker optimization, maintains system-wide volume relationships, monitors operational ranges, and adjusts offsets dynamically. This single controller performs what would otherwise require multiple independent control systems.

AI summary
A system can control volume levels of a plurality of speakers. The system can receive a selected volume level and a plurality of volume offsets corresponding to the plurality of speakers. At least two volume offsets can be different from each other. The system can calculate provisional volume levels for the plurality of speakers. Each provisional volume level can be a sum of the selected volume level and the corresponding volume offset of the speaker. When the provisional volume level is within an operational range of volume levels for the speaker, the system can set a volume level of the speaker to equal the provisional volume level. When the provisional volume level is outside the operational range of volume levels, the system can set the volume level of the speaker to equal a value within the operational range of volume levels for the speaker.
