Solution Overview
Problem
The challenge is to design a speaker device that is both thinner and more integrated, as portable electronic devices become thinner and require innovative solutions for integrating electronic components without increasing thickness.
Innovation Solution
The speaker device incorporates a vibration system, magnetic circuit system, and an auxiliary system with an antenna circuit integrated into the centering piece, allowing for antenna functions without adding thickness, achieved through a conductive circuit and pads for electrical connections, and protected by a front cover and housing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If antenna functions are integrated into the speaker device, then device functionality is improved, but device thickness increases
Solution Approach 1:
The patent combines the antenna circuit with the centering piece structure, integrating two previously separate functions (antenna and mechanical centering) into a single component. This merging eliminates the need for separate antenna elements that would increase thickness, while the centering piece's connecting arm provides both structural support and antenna functionality through its conductive circuit.
Solution Approach 2:
The centering piece is designed to serve multiple functions simultaneously: it provides mechanical centering for the voice coil, structural support between the front cover and housing, and antenna functionality through the integrated conductive circuit. This multi-functionality allows the device to gain antenna capabilities without adding dedicated antenna components that would increase thickness.
2Device complexity
If electronic components are integrated into the speaker device, then design integration level is improved, but manufacturing complexity increases
Solution Approach 1:
The antenna circuit is integrated directly into the centering piece, combining multiple electronic and mechanical functions into a single manufacturable component. This reduces the number of separate parts that need to be assembled, thereby reducing manufacturing complexity despite increasing design integration.
Solution Approach 2:
The antenna circuit is nested within the centering piece structure, with the conductive circuit embedded in the connecting arm. This nesting approach allows the antenna functionality to be housed within the existing mechanical structure, reducing the need for additional manufacturing steps and external components.
