Wireless Speaker Vibration Isolation via Elastomer Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional wireless sound equipment lacks portability and user convenience, as they often require an external terminal for operation and suffer from vibration-induced output deterioration and discomfort due to direct contact with the user's body.
Innovation Solution
A portable sound equipment design featuring a speaker module with an enclosure, separated from the housing to prevent vibration transmission, and a wireless communication unit for independent operation, allowing secure low-pitched sound output and improved user experience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the speaker module is directly mounted on the housing, then the device structure is simple, but vibration is transmitted to the user causing discomfort and output deterioration
Solution Approach 1:
The speaker module is segmented from the housing structure by introducing a vibration isolation component (elastomer) between them. This segmentation allows the speaker module to be mounted on the housing while preventing direct vibration transmission, thus maintaining structural simplicity while eliminating the harmful vibration effect.
Solution Approach 2:
A vibration isolation component made of elastomer is introduced as an intermediary between the speaker module and the housing. This intermediary element absorbs and dampens vibrations, preventing them from being transmitted to the housing and ultimately to the user, while still allowing secure mounting of the speaker module.
2Object-affected harmful factors
If the speaker module is spaced apart from the housing, then vibration transmission is prevented, but the mounting structure becomes more complex
Solution Approach 1:
The mounting structure is segmented into three functional parts: the housing, the vibration isolation component, and the speaker module. This segmentation creates a clear functional hierarchy where the vibration isolation component serves as a dedicated interface element, simplifying the overall design while achieving vibration prevention.
Solution Approach 2:
The vibration isolation component is designed to be self-contained and self-functional, providing both mechanical support for mounting the speaker module and vibration isolation in a single integrated element. This self-service approach eliminates the need for additional complex mounting mechanisms while achieving the desired vibration prevention.
3Ease of operation
If wireless communication unit is added for independent operation, then portability and user convenience are improved, but device complexity increases
Solution Approach 1:
The portable sound equipment is designed with multi-functionality by integrating both wired and wireless operation capabilities. The wireless communication unit enables independent operation without requiring connection to an external terminal, while the device maintains backward compatibility with wired connection options, thus improving user convenience without fully committing to increased complexity.

Function Achieved in This Case
The solution enhances portability and user convenience by providing clear, low-pitched sound without vibration-induced discomfort, enabling wireless operation and stable wearability through adjustable design and vibration isolation.
Implementation Method 1
a speaker module mounted in the main body and adjacent to the speaker hole
Implementation Method 2
the speaker module is secured to an inner surface of an upper case of the main body and spaced apart from the main board... blocking the vibration of the speaker module, not transmitted to the lower structure
