Solution Overview

Problem

Electronic devices with loudspeakers face issues with vibration resonance, which affects sound quality and the operation of other device elements due to the transmission of vibrations from the loudspeaker to the housing.

Innovation Solution

The use of an L-shaped holder with first and second buffer elements, where the loudspeaker is supported by the holder, and the buffer elements are connected to absorb and prevent vibration transmission to the housing, utilizing materials like rubber or foam to absorb vibrations and prolong the transmission path.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If the loudspeaker is directly mounted on the housing, then the structural simplicity is improved, but the vibration transmission to the housing increases causing resonance and affecting sound quality

Engineering Contradiction:
Improvestructural simplicityVSAvoidvibration transmission
Core Design Contradiction:
Device complexityVSObject-affected harmful factors

Solution Approach 1:

The holder serves as an intermediary component between the loudspeaker and the housing. It includes a first buffer element connected to the loudspeaker and a second buffer element connected to the housing, which acts as a mediator to absorb and isolate vibrations, preventing direct transmission from the loudspeaker to the housing while maintaining structural organization.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The buffer elements convert the harmful vibration energy into beneficial damping effects. By using materials with damping properties, the vibrations that would otherwise cause resonance and degrade sound quality are transformed into controlled energy dissipation, improving overall system performance while maintaining a relatively simple structure.

Inventive Principle:
Principle #22Blessing in disguise (Convert harm into benefit)

2Object-affected harmful factors

If buffer elements are added to reduce vibration, then the vibration transmission is reduced, but the device complexity increases

Engineering Contradiction:
Improvevibration transmissionVSAvoidstructure complexity
Core Design Contradiction:
Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The holder is segmented into distinct functional sections: a first section with a first opening for the first buffer element, and a second section with a second opening for the second buffer element. This segmentation allows each buffer element to be independently positioned and optimized for specific vibration frequencies, effectively reducing vibration transmission while keeping the overall structure organized and manageable.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The holder structure serves multiple functions simultaneously: it provides mechanical support for the loudspeaker, positions the buffer elements, and acts as a vibration isolation mechanism. By integrating these functions into a single component, the design reduces the need for additional separate parts, thereby limiting the increase in device complexity while achieving effective vibration reduction.

Inventive Principle:
Principle #6Universality (Multi-functionality)
