Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The process of designing and fine-tuning loudspeakers is laborious, requiring repeated adjustments and firmware upgrades, often taking days or weeks to achieve the desired sound, as current methods involve physical measurements in anechoic chambers and manual adjustments.
Innovation Solution
A method and system for adjusting loudspeakers via a network, allowing remote configuration and sharing of sound profiles through a graphical interface, enabling users to tune and customize equalizers, and connect speakers via Ethernet or wireless networks for real-time adjustments and profile sharing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If physical measurements and manual adjustments are performed in an anechoic chamber, then measurement precision is improved, but time consumption increases significantly
Solution Approach 1:
The patent creates a virtual copy of the anechoic chamber environment through software simulation, allowing acoustic measurements to be performed in a virtual space rather than requiring physical presence in a real anechoic chamber. This virtual model replicates the acoustic properties and measurement capabilities while enabling remote access and iteration.
Solution Approach 2:
The patent replaces the mechanical and physical measurement system with a digital/software-based system. Instead of physically moving equipment in and out of an anechoic chamber, the system uses software to perform measurements, simulate acoustic environments, and adjust parameters remotely, eliminating the need for physical manipulation and chamber access.
2Manufacturing precision
If repeated physical adjustments and firmware upgrades are performed, then sound quality is improved, but the complexity of the adjustment process increases
Solution Approach 1:
The patent implements a self-service adjustment system where the software automatically performs measurements, analyzes results, and makes adjustments based on predefined criteria and user preferences. The system guides users through the adjustment process automatically, reducing the need for expert intervention and simplifying the overall complexity while maintaining sound quality improvements.
Solution Approach 2:
The patent incorporates continuous feedback loops where measurement results are immediately analyzed and used to guide subsequent adjustments. The system provides real-time feedback to users about the effects of adjustments and automatically iterates on parameters based on measured performance, creating a streamlined process that manages complexity through systematic feedback-driven optimization.
3Manufacturing precision
If firmware upgrades are performed to achieve new equalization, then sound quality is improved, but the ease of manufacture deteriorates
Solution Approach 1:
The patent replaces static firmware with dynamic, software-based equalization that can be adjusted and updated without physical firmware flashing. The system allows users to modify equalization parameters, load different profiles, and iterate on sound settings through software interfaces, making the manufacturing and adjustment process more flexible and easier to modify compared to fixed firmware solutions.
