Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Laptop loudspeakers produce irregular sound fields due to reflections from the display, affecting frequency response and leading to poor sound play effects and reduced user experience across different usage situations.
Innovation Solution
A method and device that utilize a camera to detect user position and device parameters, adjusting audio input signals through equalizer parameters to generate optimized play signals, improving sound quality and user experience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed equalizer response is used, then the equalization process is simple, but the frequency response cannot be flattened in all usage situations
Solution Approach 1:
The patent applies dynamics by transitioning from a fixed equalizer response to a dynamic equalization system that automatically adjusts based on real-time detection of user position and device state. The system continuously monitors camera images to determine listener position and angle, then dynamically modifies equalizer parameters to optimize frequency response for each specific usage situation, thereby achieving adaptability without requiring manual intervention.
Solution Approach 2:
The patent implements feedback by using camera-based detection to continuously monitor the listener's position and the device's state, then feeding this information back to the equalization system. The system processes this feedback to automatically adjust equalizer parameters in real-time, creating a closed-loop control system that adapts the frequency response based on actual usage conditions rather than relying on predetermined fixed settings.
2Object-affected harmful factors
If the sound field is created by the loudspeaker, then the sound output is direct, but the sound field becomes irregular due to reflections from the display
Solution Approach 1:
The patent converts the harmful effect of sound reflections into a beneficial adaptive equalization system. Instead of attempting to physically eliminate reflections, the system uses camera-based detection to understand the acoustic environment created by reflections and adjusts the equalizer parameters accordingly. This transforms the problematic reflected sound field into information that guides the equalization process, resulting in optimized frequency response that compensates for the irregular sound field characteristics.
