Rollable Display Microphone Layout for Directional Recording
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The structural utilization of sound receivers in rollable flexible displays is low due to their stationary nature during unrolling and rolling, limiting the functionality of electronic devices.
Innovation Solution
The flexible display can switch between rolled and unrolled states, with the first sound receiver's position changing based on sound signal detection by the first and second sound receivers, allowing full utilization of the rollable feature and enabling functions like directional recording.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If sound receivers remain stationary during unrolling and rolling of flexible display, then the structure is simple and reliable, but the structural utilization is low and functionality is limited
Solution Approach 1:
The first sound receiver is moved from a stationary position to a movable position on the second housing that can change with the rolling/unrolling state of the flexible display. This dynamic arrangement allows the sound receiver to adapt its position based on the display state, improving structural utilization while maintaining reasonable system complexity through automated position adjustment.
2Adaptability or versatility
If the first sound receiver moves with the second housing, then directional recording and other functions are enabled, but the device complexity increases
Solution Approach 1:
The system uses the flexible display's own rolling/unrolling motion to automatically position the first sound receiver on the second housing without requiring external actuation mechanisms. The display's inherent movement serves the dual purpose of changing display area and positioning the sound receiver, thereby enabling new functions while avoiding additional complexity from separate positioning systems.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This solution enhances the structural utilization of the electronic device by allowing the first sound receiver to move with the second housing, implementing more functions and reducing component complexity and cost.
Implementation Method 1
allowing the sound emitted by the sound emitter to be picked up by both the first sound receiver and the second sound receiver

AI summary
This application discloses an electronic device, a control method and control apparatus therefor, and a readable storage medium. The electronic device includes a first housing, a second housing, a flexible display, a sound emitter, a first sound receiver, a second sound receiver, and a third sound receiver. The second housing is capable of moving relative to the first housing such that the flexible display switches between a rolled state and an unrolled state. The sound emitter is disposed inside the first housing, and the sound emitter is in communication with the outside via a first sound outlet hole. The first sound receiver is disposed inside the second housing, and the first sound receiver is in communication with the outside via a first sound receiving hole. The second sound receiver and the third sound receiver are both disposed inside the first housing, the second sound receiver is in communication with the outside via a second sound receiving hole, and the third sound receiver is in communication with the outside through a third sound receiving hole. In the rolled state, the first housing covers the first sound receiving hole; and in the unrolled state, the first sound receiving hole is exposed, and the first sound receiver is in communication with the outside.
