Speaker Rear Cavity Structure to Reduce Space and Vibration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic devices with semi-open speakers occupy a large space due to their rear cavity, which is not efficiently utilized, and the fast-flowing gas during speaker operation can cause vibrations affecting other components, degrading user experience.
Innovation Solution
The speaker, speaker bracket, and main board bracket jointly create a closed rear cavity, reducing the need for additional components and ensuring good sealing to prevent gas escape, thereby minimizing space occupation and avoiding component vibrations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a semi-open speaker is used to lower costs, then the cost is reduced, but the speaker occupies a relatively large space due to its rear cavity
Solution Approach 1:
The patent merges the speaker rear cavity formation into the existing bracket structure. The speaker bracket and main board bracket jointly create the closed rear cavity with the speaker, eliminating the need for separate rear cavity components. This integration reduces the overall space occupied by the speaker assembly while maintaining the semi-open speaker's cost-effectiveness.
2Reliability
If additional components are added to create speaker rear cavity, then the sealing is improved, but the device complexity increases
Solution Approach 1:
The speaker bracket serves multiple functions: it supports the speaker, forms part of the closed rear cavity structure, and contributes to the sealing system. The main board bracket also serves dual purposes by providing structural support and participating in rear cavity formation. This multi-functionality reduces the need for additional dedicated components while maintaining reliable sealing.
3Ease of manufacture
If the speaker rear cavity is not properly sealed, then the manufacturing is easier, but fast-flowing gas escapes and causes vibrations affecting other components
Solution Approach 1:
By integrating the sealing function into the bracket structures themselves, the patent creates a sealed rear cavity without requiring separate sealing components. The speaker bracket and main board bracket form the sealed enclosure that contains fast-flowing gas, preventing it from escaping and causing vibrations to other components while maintaining relatively simple manufacturing.
