Movable Microphone Mount for Stable Audio During Video Shake
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Microphones in electronic devices, such as smartphones, are prone to changing angles relative to the sound source due to device shaking during video recording, affecting the recording quality.
Innovation Solution
The microphone module is mounted on a movable support that moves in sync with a lens assembly, maintaining a consistent angle with the sound source by using a shake detection apparatus to adjust the movable support based on detected shake parameters.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the microphone is fixed on the motherboard or auxiliary board, then the device structure is simple and easy to manufacture, but the microphone position changes relative to the sound source during device shaking, causing angle changes that affect recording quality
Solution Approach 1:
The patent applies the dynamics principle by mounting the microphone on the movable support that can dynamically adjust its position. The movable support moves synchronously with the lens assembly during optical stabilization, allowing the microphone to maintain a consistent angle with the sound source even when the device shakes, thereby resolving the contradiction between fixed simple installation and stable recording quality
Solution Approach 2:
The patent merges the microphone mounting with the movable support structure that already exists for lens stabilization. By combining these functions, the microphone benefits from the same positional stability mechanisms without requiring a separate fixed mounting system, thus improving recording quality while maintaining manufacturing efficiency
2Device complexity
If the microphone is disposed on the motherboard, then the device structure is compact, but the microphone cannot move synchronously with the lens, resulting in angle changes during shaking that affect sound recording
Solution Approach 1:
The microphone is mounted on the movable support which dynamically adjusts its position to match lens movement during stabilization. This dynamic mounting allows the microphone to maintain reliable, consistent angular relationship with the sound source while preserving the overall compact device structure
Solution Approach 2:
The movable support structure serves multiple functions: it stabilizes the lens optically and simultaneously provides a stable mounting platform for the microphone. This multi-functionality reduces device complexity while ensuring reliable sound recording consistency
