Speaker Balance Element Stabilizes Voice Coil
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Speakers with higher power output often experience unstable voice coil movement, leading to horizontal shaking and reduced high-frequency sensitivity, which affects treble quality.
Innovation Solution
A speaker design that includes a frame, magnetic circuit system, balance element, and diaphragm, where the balance element with a deforming portion is connected to the voice coil and bearing surface, compressing or stretching to stabilize the voice coil's movement path and prevent horizontal shaking.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If higher power output is achieved by increasing voice coil displacement range, then power output is improved, but movement stability deteriorates causing horizontal shaking
Solution Approach 1:
The balance element serves as an intermediary component between the voice coil and the frame. It includes a first fixing portion connected to the voice coil, a second fixing portion connected to the frame, and a deforming portion between them. This intermediary structure absorbs lateral forces and stabilizes the voice coil's movement path, preventing horizontal shaking while allowing the voice coil to achieve larger displacement ranges for higher power output.
2Power
If voice coil displacement range is increased for higher power, then power output is improved, but horizontal shaking increases affecting treble quality
Solution Approach 1:
The balance element acts as a mediator that connects the voice coil to the frame structure. Its deforming portion flexes to accommodate the voice coil's larger displacement movements while filtering out harmful horizontal shaking motions, thus allowing high power output without compromising treble quality.
Solution Approach 2:
The balance element's deforming portion changes its physical state by flexing and deforming during operation. This parameter change allows it to dynamically adapt to the voice coil's movement, absorbing lateral forces and maintaining stable motion even at larger displacement ranges required for high power output.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This design stabilizes the voice coil's movement, enhancing high-frequency sensitivity and maintaining treble quality by preventing unexpected horizontal shaking and improving frequency response.
Implementation Method 1
the deforming portion of the balance element may be compressed or stretched with the movement of the voice coil, so as to achieve the effect of stabilizing the moving path of the voice coil
Implementation Method 2
a speaker may make the diaphragm vibrate by the movement of the voice coil under the action of the electromagnetic force to emit sound
