Audio Component Ratio Control for Clear Dialogue at Low Volume
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face difficulties in adjusting specific audio components in electronic devices, such as TVs, as existing methods require manual selection of acoustic modes from menus, leading to discomfort and limited control over audio components, especially when reducing volume, which can make it hard to hear important audio elements like performer's lines.
Innovation Solution
An electronic apparatus with an audio processor and controller that separates audio into components and adjusts their gain ratios based on user input, ambient conditions, or previous usage history to emphasize specific audio components, such as voice or background audio, without manual selection, allowing for enhanced user convenience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the user manually selects acoustic modes from a menu to adjust audio components, then the user can control specific audio components, but the operation becomes complex and inconvenient
Solution Approach 1:
The electronic apparatus automatically adjusts audio components based on ambient conditions (lighting, noise levels) and usage history without requiring manual menu selection. The system serves itself by detecting environmental factors and autonomously optimizing audio output, eliminating the need for complex user interactions while maintaining ease of operation
Solution Approach 2:
The system pre-configures audio components based on previously stored usage patterns and environmental conditions. By anticipating user preferences through historical data analysis, the apparatus prepares optimal audio settings in advance, allowing users to simply select presets rather than manually adjusting each component through complex menus
2Object-affected harmful factors
If the user reduces the overall volume of audio, then the audio output is lowered to avoid disturbance, but all audio components including important elements like performer's lines are decreased
Solution Approach 1:
The audio signal is segmented into multiple components (performer's lines, background music, sound effects) that can be independently controlled. When overall volume needs reduction, the system selectively adjusts only the necessary components (e.g., lowering background music) while maintaining critical elements (performer's lines) at adequate levels, preventing information loss while reducing disturbance
Solution Approach 2:
Different audio components are assigned different quality priorities based on their importance. Performer's lines are given higher local quality weight and are preserved even when overall volume is reduced, while less critical components are more aggressively lowered. This localized quality management ensures important information is retained while minimizing disturbance

AI summary
An electronic apparatus and a method for controlling the electronic apparatus are provided. The electronic apparatus includes an audio processor that outputs an audio including a first audio component and a second audio component and a controller that controls the audio processor to change a ratio of the first audio component to the second audio component according to the changed audio level, in response to receiving an instruction to change a level of the output audio.
