Balanced Iron Core Vibration System for Signal Efficiency
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vibration systems, particularly of the moving iron type, suffer from low signal conversion efficiency and energy loss due to unbalanced vibration, resulting in distortion.
Innovation Solution
A balanced vibration system is designed with a magnetic circuit unit, a vibration unit, and a casing, where a balanced iron core, made of magnetically-conductive material, is movably connected to the casing and driven by two magnet groups with opposing magnetic poles, enabling equal magnetic forces to induce vibration in the diaphragm for efficient sound generation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If a balanced iron core with one end fixed and the other end vibrating is used, then the vibrating end can generate vibration by overcoming elastic stress, but this leads to energy loss and distortion
Solution Approach 1:
Instead of fixing one end of the balanced iron core and allowing the other end to vibrate freely (which causes energy loss through elastic stress), the patent inverts the approach by fixing the iron core at its center and allowing both ends to vibrate symmetrically. This inversion eliminates the elastic stress loss mechanism while maintaining vibration generation capability.
Solution Approach 2:
The balanced iron core is segmented into two symmetric halves that can vibrate independently but simultaneously. By treating the core as two separate vibrating sections rather than one fixed-end system, the patent achieves balanced vibration that reduces energy loss and eliminates distortion.
2Use of energy by moving object
If a moving iron type vibration system is used, then the system can generate sound through magnetic field forces, but signal conversion efficiency is low and power consumption is high
Solution Approach 1:
The patent changes the physical parameters of the vibration system by using a balanced iron core with symmetric magnet groups instead of a conventional moving iron configuration. This parameter change optimizes the magnetic field distribution and vibration mechanics, resulting in improved signal conversion efficiency and reduced power consumption.
Solution Approach 2:
While the overall system maintains symmetry for balanced vibration, the patent introduces asymmetric magnet group configurations (with different numbers of magnets at each end) to optimize the magnetic field distribution. This controlled asymmetry in magnet arrangement improves signal conversion efficiency while maintaining the balanced vibration characteristic.
3Device complexity
If single-side vibration is used, then the system structure is simple, but distortion is generated and vibration cannot go on fully
Solution Approach 1:
Instead of implementing a simple single-side vibration system, the patent inverts the approach by creating a dual-side vibration system with symmetric magnet groups. This inversion, while increasing structural complexity, enables complete vibration operation without distortion by allowing both ends of the balanced iron core to vibrate simultaneously.

Function Achieved in This Case
This configuration achieves higher signal conversion efficiency, reduces power consumption, and eliminates distortion by allowing the balanced iron core to vibrate fully, effectively converting electrical signals into sound without single-side vibration issues.
Implementation Method 1
a magnetic circuit coil vibrates to drive a vibrating diaphragm to vibrate so as to generate sound
Implementation Method 2

Implementation Method 4
the balanced iron core drives the vibrating diaphragm to vibrate up and down for sound generation
