Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional large-sized display devices with integrated loudspeakers suffer from poor acoustic fidelity due to lack of resonance and inefficient sound signal transmission, making it difficult to replicate the natural sound production of human voice.
Innovation Solution
A sound system with a partitioned box body containing two chambers, where the loudspeaker's vibration side is connected to one chamber and its opposite side is connected to another, allowing for external communication through sound wave channels and resonance cover plates, enhancing resonance and acoustic fidelity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a loudspeaker is mounted directly on a holder in a simple box body, then the device complexity is reduced, but the acoustic fidelity deteriorates due to lack of resonance
Solution Approach 1:
The box body is segmented into multiple chambers (first chamber, second chamber, third chamber) separated by partition boards, allowing each chamber to function as an independent resonance cavity. This segmentation enables complex acoustic behavior while maintaining a relatively simple overall structure.
Solution Approach 2:
The patent utilizes mechanical vibration principles by creating resonance cavities that vibrate in response to loudspeaker output. The partition boards and chamber designs are specifically configured to produce resonant frequencies that enhance acoustic fidelity, mimicking human voice production mechanisms.
2Ease of manufacture
If a simple box body structure is used, then the ease of manufacture is improved, but the acoustic quality deteriorates
Solution Approach 1:
The internal space is divided into multiple chambers using partition boards, which can be manufactured as separate components and assembled into the box body. This segmentation allows for easier manufacturing of individual parts while achieving complex acoustic functionality through their combination.
Solution Approach 2:
The partition boards serve multiple functions: they separate chambers for resonance, provide mounting surfaces for the loudspeaker, and structure the overall box body. This multi-functionality reduces the need for additional specialized components, simplifying manufacturing.
3Manufacturing precision
If multiple chambers are introduced to improve resonance, then the acoustic fidelity is improved, but the device complexity increases
Solution Approach 1:
The box body is segmented into multiple chambers (first chamber, second chamber, third chamber) separated by partition boards, allowing each chamber to function as an independent resonance cavity. This segmentation enables complex acoustic behavior while maintaining a relatively simple overall structure.
Solution Approach 2:
Multiple resonance chambers are merged within a single box body structure, with partition boards creating distinct acoustic zones that work together. The loudspeaker serves as a common input for all chambers, combining their resonant outputs to achieve enhanced acoustic fidelity.

AI summary
The present disclosure provides a sound system. The sound system includes a box body and a loudspeaker arranged in the box body. An internal space of the box body is partitioned into a first chamber and a second chamber by a partition board in a sounding vibration direction of the loudspeaker. A vibration side of the loudspeaker is intercommunicated with the first chamber, and a side of the loudspeaker opposite to the vibration side is intercommunicated with the second chamber. At least one of the first chamber and the second chamber is intercommunicated with the outside.
