Flexible Display Voice Calls With Adaptive Microphone Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In terminals with flexible display screens, the distance variation between microphones and the sound source during voice calls affects sound reception quality, particularly when the display is in a roll-up state, leading to poor call quality.
Innovation Solution
A voice call method and apparatus that adjusts the flexible display screen to spread out when in a roll-up state, reducing the distance between the radio microphone and the sound source, and utilizes noise reduction microphones to enhance sound reception and quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the flexible display screen is in a roll-up state during a voice call, then the terminal maintains a compact form factor, but the distance between the radio microphone and the sound source increases, degrading sound reception quality
Solution Approach 1:
The patent applies the dynamics principle by making the flexible display screen changeable between roll-up and spread-out states based on the call mode. During voice calls, the screen automatically spreads out to reduce the distance between the radio microphone and sound source, improving sound reception quality. This dynamic adjustment resolves the contradiction between maintaining a compact form factor and ensuring high sound reception quality.
2Manufacturing precision
If the flexible display screen spreads out during a voice call, then the distance between the radio microphone and the sound source decreases, improving sound reception quality, but the terminal loses its compact form factor
Solution Approach 1:
The patent implements dynamic state adjustment where the flexible display screen automatically transitions between roll-up and spread-out configurations based on detected call modes. When a voice call is detected, the screen spreads out to optimize microphone-to-sound-source distance, thereby improving sound reception quality while temporarily sacrificing compact form factor only when necessary.
Solution Approach 2:
The patent changes the physical parameter of the display screen configuration (roll-up vs. spread-out state) in response to different operating conditions (call modes). This parameter change allows the system to optimize sound reception quality by adjusting the screen state to reduce microphone-to-sound-source distance during voice calls.
3Manufacturing precision
If the terminal uses noise reduction microphone for noise removal, then the sound reception quality improves, but the system complexity increases due to multiple microphones and processing requirements
Solution Approach 1:
The patent applies the multi-functionality principle by using the flexible display screen structure to serve dual purposes: display functionality and acoustic optimization. The screen's ability to change configuration directly impacts sound reception quality, allowing the system to achieve noise reduction and quality improvement without adding separate complex hardware components or processing systems.

AI summary
Provided are a voice call method, an apparatus, a terminal, and a storage medium, relating to the technical field of the terminal. The method includes: obtaining, in response to a voice call instruction, a display screen state of the flexible display screen, the display screen state comprising at least one of a roll-up state and a spread-out state; controlling, in response to the flexible display screen being in the roll-up state, the flexible display screen to spread out, wherein the first housing and the second housing move relative to each other while spreading out the flexible display screen, and wherein a distance between the sound receiving hole and a sound source after the spreading out is smaller than a distance between the sound receiving hole and the sound source before the spreading out; and collecting call voice through the radio microphone.
