Split-Screen Audio Volume Control Across Display Areas
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electronic devices output audio data based on the volume configured in each application, regardless of the display areas, leading to inconvenience when switching between multiple display areas and a single display area, requiring manual volume adjustments in each application.
Innovation Solution
The electronic device controls audio data output based on the volume configured in each display area, allowing independent volume control for each display area, maintaining consistent volume settings during transitions between multiple and single display configurations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the media player supports multiple functions (audio, video, subtitles, audio book), then the functionality and versatility are improved, but the device complexity increases
Solution Approach 1:
The media player is designed to perform multiple functions including playing audio files, video files, subtitle files, and audio books through a single integrated device. The controller automatically detects the file type and switches between different playback modes, allowing one device to replace multiple specialized devices.
2Adaptability or versatility
If the volume control range is extended to very low levels (e.g., -60dB or -80dB), then the volume control range is improved, but the distortion and noise increase
Solution Approach 1:
The volume control range is divided into multiple discrete levels rather than allowing continuous adjustment to extremely low values. The controller segments the volume range into manageable steps (e.g., from 0dB to -60dB in controlled increments), preventing the system from entering distortion-prone territory while still providing sufficient volume reduction for different listening environments.
3Ease of operation
If the volume is adjusted in real-time during playback, then the ease of operation is improved, but the audio quality deteriorates due to distortion
Solution Approach 1:
The volume control system allows dynamic adjustment during playback through a user interface, enabling users to change volume levels at any time. The controller dynamically processes volume changes by adjusting the gain stages in real-time, balancing user convenience with maintaining acceptable audio quality by preventing excessive volume reduction.
