Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The complexity and cost of speaker manufacturing and assembly are increased by the need for separate washers and conductive sheets in traditional speaker designs, which complicate the formation of a uniform magnetic field.
Innovation Solution
An integral washer conductive sheet is integrated into the speaker structure, combining a washer part for correcting magnetic lines and a conductive sheet part for signal conduction, made of permeable magnetic material, with an insulating material separating the sheet from the magnets to prevent interference, and fixedly coupled with the casing to simplify assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate washers and conductive sheets are used in traditional speaker designs, then magnetic field correction and signal conduction functions are achieved, but device complexity and manufacturing cost increase
Solution Approach 1:
The patent combines the washer structure and conductive sheet into a single integrated component called the 'integral washer conductive sheet'. This unified structure performs both magnetic field correction (through the washer part) and signal conduction (through the conductive sheet part) simultaneously, eliminating the need for separate components and reducing assembly steps.
Solution Approach 2:
The integral washer conductive sheet serves multiple functions: it corrects magnetic lines around the peripheral magnets, conducts electrical signals from the external signal source to the voice coil, and provides structural support. This multi-functional design reduces the total number of components needed in the speaker system.
2Reliability
If separate washers and conductive sheets are used in traditional speaker designs, then magnetic field correction and signal conduction functions are achieved, but manufacturing and assembly costs increase
Solution Approach 1:
The washer and conductive sheet are manufactured as a single integrated part, which simplifies the manufacturing process by reducing the number of machining operations, material handling steps, and quality inspection points. This integration directly reduces manufacturing complexity and associated costs.
3Reliability
If separate washers and conductive sheets are used in traditional speaker designs, then magnetic field correction and signal conduction functions are achieved, but assembly time and production efficiency decrease
Solution Approach 1:
By integrating the washer and conductive sheet into a single component, the assembly process is simplified from installing two separate parts to installing one unified component. This reduction in assembly steps directly improves production efficiency and reduces assembly time.
