Screen-Integrated Speaker Cavity Structure for Thinner Foldables
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 affect 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 due to thickness superimposition
Solution Approach 1:
The patent merges the wall plate function with the first screen part by using the first screen part to form the wall plate of the front cavity. This integration eliminates the need for a separate wall plate, avoiding thickness superimposition while maintaining structural completeness and protective functions.
2Reliability
If a wall plate is provided for the sound output channel, then the sound output channel is enclosed and protected, but the thickness of the electronic device increases
Solution Approach 1:
The patent uses the first wall plate part to form the wall plate of the sound output channel, merging the enclosure function with the existing wall plate structure. This eliminates the need for an additional wall plate while maintaining sound output channel enclosure and protection.
3Adaptability or versatility
If multiple separate components are used for the speaker module, then each component can be optimized independently, but the overall device thickness increases due to stacking
Solution Approach 1:
The patent integrates multiple functions into the first screen part and first wall plate part, including wall plate formation, sound output channel enclosure, and structural support. This integration reduces the number of stacked components while maintaining the ability to optimize each function through careful design of the integrated structures.

AI summary
This application provides an electronic device, and relates to the field of electronic product technologies, to reduce a thickness of the electronic device and improve portability and tactile experience of the electronic device. The electronic device includes a screen and a speaker module. The screen includes a first screen part, and the first screen part includes a first display surface. The speaker module is located at a side that faces away from the first display surface and that is of the first screen part, and the speaker module includes a core. A front cavity of the speaker module is arranged between the core and the first screen part, and at least a part of the first screen part forms a wall plate of the front cavity. The electronic device provided in this application is configured to play voice or music.
