Screen-Integrated Speaker Cavity for Thinner Foldable Electronics
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The thickness of electronic devices, particularly foldable-screen devices, is hindered by the speaker modules and dustproof structures, which obstruct further reduction in thickness and impact portability and tactile experience.
Innovation Solution
The speaker module is integrated with the screen's first screen part to form part of its wall plate, eliminating the need for a separate wall plate, and the sound output channel is designed without a wall plate adjacent to the screen, reducing thickness and enhancing sound output efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a separate wall plate is provided for the speaker module, then the speaker module structure is complete and protective, but the thickness of the electronic device increases
Solution Approach 1:
The patent merges the wall plate function with the first screen part by making the screen part itself form the wall plate of the front cavity. This integration eliminates the need for a separate wall plate component, thereby reducing device thickness while maintaining the protective and structural functions.
Solution Approach 2:
The first screen part is designed to serve multiple functions: it acts as both the display component and the wall plate of the speaker module's front cavity. This multi-functionality reduces the number of separate components needed and minimizes overall device thickness.
2Stability of the object's composition
If a wall plate is provided for the sound output channel, then the channel structure is complete, but thickness superimposition occurs and device thickness increases
Solution Approach 1:
The patent merges the sound output channel wall plate function with the first screen part. The screen part forms both the front cavity wall plate and the sound output channel wall plate, eliminating separate wall plate structures and reducing thickness superimposition.
Solution Approach 2:
The patent extracts the wall plate function from separate components and integrates it into the first screen part. This extraction and integration approach eliminates redundant structures while maintaining channel integrity.
3Ease of manufacture
If the speaker module is designed with traditional separate components, then manufacturing is straightforward, but device thickness cannot be reduced further
Solution Approach 1:
The patent combines multiple traditional separate components (front cavity wall plate, sound output channel wall plate) into the first screen part. This merging maintains manufacturing simplicity while achieving significant thickness reduction.
