Networked Speaker Tuning Through Remote Sound Profile Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The process of designing and fine-tuning loudspeakers is laborious, requiring repeated adjustments and measurements, which can take days or weeks to achieve the desired sound quality, as existing methods often necessitate physical changes to electrical components and firmware updates within anechoic chambers.
Innovation Solution
A method and system that allow for remote adjustment of loudspeakers via a network, using a graphical interface to tune and configure equalizers, enabling users to adjust and share sound profiles across multiple speakers, utilizing Ethernet or wireless connections to update settings in real-time.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If physical adjustments and firmware updates are performed repeatedly in an anechoic chamber, then manufacturing precision of sound quality is improved, but loss of time increases significantly
Solution Approach 1:
The patent creates virtual copies of the anechoic chamber environment through software simulation and digital signal processing. Instead of physically moving speakers in and out of a real anechoic chamber for each measurement, the system uses acoustic measurement microphones and software to create virtual measurement environments, allowing rapid iteration without physical transport time.
Solution Approach 2:
The patent replaces the mechanical process of physically transporting speakers to and from an anechoic chamber with an automated electronic measurement system. The system uses microphones positioned in the chamber that can measure multiple speaker configurations sequentially, eliminating the need for manual physical handling and setup time.
2Adaptability or versatility
If electrical components are repeatedly changed to generate new equalization, then adaptability of sound profiles is improved, but device complexity increases
Solution Approach 1:
The patent implements software-based equalization that allows dynamic adjustment of frequency response parameters without physically changing electrical components. The system uses digital signal processing to modify equalization parameters, enabling rapid switching between different sound profiles and equalization settings through software configuration rather than hardware modification.
3Adaptability or versatility
If firmware updates are performed to achieve new sound characteristics, then product functionality is improved, but loss of time increases due to repeated updates
Solution Approach 1:
The patent creates virtual firmware updates through software configuration files that define different sound characteristics. Instead of requiring actual firmware flashing operations for each sound profile change, the system loads different configuration parameters and equalization settings from software, providing the effect of firmware updates without the time-consuming update process.
