Foldable Housing Speaker Hole Configuration for Sound Quality
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Portable electronic devices with flexible housings, such as smartphones, face challenges in maintaining sound quality due to limited internal mounting space, which restricts the volume of the speaker passage, leading to deteriorated sound output.
Innovation Solution
The electronic device incorporates a foldable housing with strategically positioned speaker holes that change configuration based on the device's unfolded or folded state, utilizing the altered structural space to enhance sound passage and quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the speaker volume is increased to improve sound quality, then the sound output quality is improved, but the device volume increases which contradicts the portable design requirement
Solution Approach 1:
The housing transitions between unfolded and folded states to dynamically change the internal space available for the speaker passage. When folded, the housing creates additional volume for the speaker passage, improving sound quality without increasing the device's external dimensions when unfolded.
Solution Approach 2:
The speaker passage is nested within the housing structure itself, utilizing the housing walls and folded configuration to create the passage volume. This eliminates the need for separate dedicated speaker chambers, as the housing structure provides the necessary volume when folded.
2Reliability
If the speaker passage volume is increased to improve sound quality, then the sound output quality is improved, but the mounting space for other internal elements is reduced
Solution Approach 1:
The housing configuration changes between unfolded and folded states to provide adequate space for both the speaker passage and other internal elements. When unfolded, space is optimized for component mounting; when folded, space is optimized for the speaker passage volume.
Solution Approach 2:
Different regions of the housing serve different functions depending on the device state. The housing structure provides mounting space for internal elements in the unfolded state, while creating localized volume for the speaker passage in the folded state.
3Strength
If the housing is made rigid to maintain structural integrity, then the structural strength is improved, but the flexibility to change shape for optimizing speaker passage is reduced
Solution Approach 1:
The housing employs flexible materials and结构设计 that allow it to bend and fold while maintaining structural integrity. The housing can transition between unfolded and folded states, adapting its shape to optimize the speaker passage volume without compromising strength.
Solution Approach 2:
The housing is designed as a dynamic structure that can change its configuration between unfolded and folded states. This adaptability allows the housing to optimize the speaker passage volume when folded while maintaining sufficient structural strength for portability.

AI summary
An electronic device includes a foldable housing including a first surface, a second surface, and a side surface surrounding a portion of a space between the first surface and the second surface, and a speaker disposed inside the housing. The housing further includes a hinge unit, a first speaker hole formed in a partial area of the side surface, which is adjacent to the speaker, and a second speaker hole formed in a partial area of the first surface, which is adjacent to the speaker. The first speaker hole is opened and the second speaker hole is closed in a state in which the housing is unfolded, and the first speaker hole is closed and the second speaker hole is opened in a state in which the housing is folded.
