Speaker Box Elastic Cushion Fixing Structure
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing speaker boxes in portable devices suffer from poor acoustic performance due to inconsistent adhesive layers and risk of internal component separation during drops, as the speaker is typically fixed to the supporting wall only by adhesive.
Innovation Solution
Incorporating an elastic cushion between the supporting wall and the speaker's frame, which enhances acoustic performance by ensuring consistent engagement and acts as a buffering structure to protect internal components during impacts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the speaker is fixed to the supporting wall only by adhesive, then the device complexity is reduced, but the acoustic performance deteriorates due to poor consistency of the adhesive layer
Solution Approach 1:
The patent introduces an elastic cushion as an intermediary component between the speaker and the supporting wall. This cushion ensures consistent contact and uniform force distribution, resolving the adhesive layer inconsistency problem while maintaining structural simplicity. The elastic cushion acts as a mediator that improves acoustic performance without significantly increasing device complexity.
2Ease of manufacture
If the speaker is fixed only by adhesive, then the manufacturing process is simplified, but the reliability deteriorates during dropping as internal components separate
Solution Approach 1:
The patent applies beforehand cushioning by pre-installing an elastic cushion between the speaker and the supporting wall before assembly. This cushion is designed to absorb impact energy during drops, preventing internal component separation. The cushioning structure is integrated into the manufacturing process, maintaining ease of manufacture while dramatically improving impact resistance and reliability.
3Reliability
If an elastic cushion is added between the supporting wall and speaker, then the acoustic performance and impact resistance are improved, but the device complexity increases
Solution Approach 1:
The patent employs a thin elastic cushion film rather than a bulky cushioning structure. This flexible thin film maintains consistent contact between the speaker and supporting wall, improving acoustic performance while minimizing space occupation and structural complexity. The thin film design allows easy integration into the existing device architecture without significant complexity increase.
4Reliability
If an elastic cushion is added between the supporting wall and speaker, then the impact protection is improved, but the device complexity increases
Solution Approach 1:
The patent changes the physical parameters of the cushioning material to achieve optimal protection with minimal complexity. By selecting specific elastic materials with appropriate hardness, thickness, and damping characteristics, the cushion provides effective impact protection while maintaining a compact design. The parameter optimization allows the buffering structure to be integrated without significantly increasing overall device complexity.

AI summary
The present application discloses a speaker box. The speaker box includes an upper cover, a lower cover forming an accommodation space with the upper cover, and a speaker received in the accommodation space. The speaker includes a frame and a diaphragm positioned by the frame. The upper cover forms a supporting wall extending toward the lower cover for fixing the speaker. The speaker box further includes an elastic cushion arranged between the frame and the supporting wall. A method for assembling the speaker box is also provided. Due to the elastic cushion, the consistency of the speaker is ensured, and the acoustic performance of the speaker box is accordingly improved.
