Double-Sided Speaker with H-Magnet and Counterweight
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional speakers face challenges in achieving two-way sounding with constant size, as increased low-frequency or voltage leads to diaphragm oscillation, causing cabinet resonance and resulting in noise and distortion.
Innovation Solution
A double-sided vibrating speaker design featuring a magnet member with an H-shaped main magnetic unit, two vibration members, and diaphragms, where each vibration member has a voice coil and diaphragm, and air vents and open pores to offset forces and reduce resonance, allowing for two-way sounding without increasing size.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If the speaker is installed in a cabinet to improve low-frequency performance, then the low-frequency output is improved, but the cabinet resonates with the speaker causing noise and distortion
Solution Approach 1:
The patent extracts the magnet assembly and one vibration member from the traditional cabinet enclosure, creating a self-contained dual-sided speaker unit that eliminates the cabinet resonance problem while maintaining low-frequency performance
Solution Approach 2:
The patent uses the second vibration member as a counterweight to offset the vibration and resonance generated by the first vibration member, reducing noise and distortion while maintaining acoustic output
2Power
If the low frequency or voltage of the speaker increases, then the output volume and bass are improved, but the diaphragm produces large amplitude oscillation causing the entire speaker to vibrate
Solution Approach 1:
The second vibration member acts as a counterweight to the first vibration member, offsetting large amplitude oscillations and preventing the entire speaker from vibrating when low frequency or voltage increases
Solution Approach 2:
The patent combines two vibration members with opposite vibration directions into a single integrated unit, allowing them to counterbalance each other's vibrations while maintaining individual acoustic output
3Power
If a double-sided vibrating speaker is designed to achieve two-way sounding with constant size, then the output volume and bass are increased, but the vibration control becomes more challenging
Solution Approach 1:
The patent merges two vibration members into a single integrated dual-sided speaker unit, allowing them to counterbalance vibrations naturally through their opposite movements, thereby simplifying vibration control despite increased power output
