Solution Overview

Problem

Conventional speaker driver structures are hindered by a thick thickness and poor sensitivity due to the weight of plastic fixers, leading to voice distortion.

Innovation Solution

A driver structure comprising a voice coil, a suspension mechanism with a fixer, diaphragm, and spider, along with at least two wires and a holder with a terminal set, where the magnetic circuit element is integrated to reduce thickness and enhance sensitivity, using materials like aluminum for the diaphragm and metal or non-metallic materials for other components.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If a plastic fixer is used in the driver structure, then the structure is easier to manufacture, but the weight of the suspension system increases causing thick thickness and poor sensitivity

Engineering Contradiction:
Improveease of manufactureVSAvoidweight of suspension system
Core Design Contradiction:
Ease of manufactureVSWeight of moving object

Solution Approach 1:

The patent removes the plastic fixer from the driver structure entirely, replacing it with a metal fixer that is integrated into the suspension system. This extraction of the problematic plastic component directly reduces the weight of the moving object while maintaining manufacturing feasibility through the metal alternative.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The patent changes the material parameter of the fixer from plastic to metal, which fundamentally alters the weight characteristic. This material substitution reduces the weight of the suspension system while preserving the structural and manufacturing advantages of the fixer component.
