Mobile Terminal Speaker Control for Interference Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The challenge in mobile terminals is ensuring a consistent and effective sound effect when multiple speakers are used, as they often interfere with each other, leading to a compromised audio experience.
Innovation Solution
A speaker control method that determines the use state of a mobile terminal and adjusts the audio modes of its speakers accordingly, ensuring they cooperate without interference by switching between different audio modes such as mono-channel, mixed-channel, and off modes based on the terminal's state, such as screen folding or display mode.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If more speakers are added to improve sound effect, then audio quality can be enhanced, but speaker interference increases and sound effect deteriorates
Solution Approach 1:
The patent implements dynamic audio mode switching that adjusts speaker operation modes based on real-time use states. The system transitions between mono-channel mode, mixed-channel mode, and off mode depending on whether the terminal is in pocket, on table, or handheld states, thereby dynamically preventing speaker interference while maintaining optimal sound quality for each scenario.
Solution Approach 2:
The system changes operational parameters of speakers by switching between different audio modes (mono-channel, mixed-channel, off). These parameter changes are triggered by detected use states such as pocket mode, table mode, and handheld mode, allowing the speakers to operate in interference-free configurations for each specific usage scenario.
2Ease of operation
If speakers operate in fixed modes, then control is simple, but sound effect is affected when speakers interfere with each other
Solution Approach 1:
The system automatically detects the terminal's use state and autonomously switches between audio modes without requiring manual user intervention. The speaker control mechanism serves itself by monitoring use states (pocket, table, handheld) and independently adjusting speaker configurations to prevent interference, thereby maintaining both ease of operation and sound quality.
Solution Approach 2:
The system implements a feedback mechanism where the detected use state informs the speaker mode selection. The terminal continuously monitors its physical state and uses this feedback to dynamically adjust speaker operating modes, ensuring that speakers operate in configurations that prevent interference for the current usage scenario.
