Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The unbalanced weights in the welding plate structure of micro speakers cause the single-body to swing, affecting sound quality in mobile communication equipment.
Innovation Solution
A micro speaker design that includes a balance component fixed to the skeleton where the voice coil is located, balancing the weight of the welding plate structure and lead wire, ensuring symmetry and stable vibration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the welding plate structure is arranged on one side of the skeleton, then the electrical connection is simplified, but the weight becomes unbalanced causing single-body swing
Solution Approach 1:
A balance component is added to the skeleton structure to counterbalance the weight of the welding plate and lead wire. The balance component has a weight substantially equal to the combined weight of the welding plate and lead wire, positioned to achieve weight balance and prevent single-body swing during vibration.
2Ease of manufacture
If the welding plate structure is arranged on one side of the skeleton, then the assembly process is simplified, but the sound quality deteriorates due to swinging
Solution Approach 1:
The balance component compensates for the asymmetric weight distribution caused by the welding plate structure, eliminating the swinging motion that degrades sound quality while maintaining the simplified one-sided arrangement of the welding plate.
3Ease of operation
If the welding plate structure and lead wire are placed on one side, then the electrical connection is more convenient, but the weight distribution becomes unbalanced
Solution Approach 1:
The balance component is designed to have a weight substantially equal to the combined weight of the welding plate and lead wire, creating a counterbalancing effect that achieves weight distribution balance while allowing the welding plate and lead wire to remain conveniently positioned on one side for electrical connection.

AI summary
The present invention provides a micro speaker, including a frame with a containment space, and a magnetic circuit system and a vibration system contained in the containment space. The vibration system includes a first diaphragm, a circuit board, a skeleton, and a voice coil. The micro speaker further includes a welding plate structure and a balance component. The voice coil includes a lead wire electrically connected with the welding plate structure. By setting the balance component on the skeleton, the present invention can keep the weight balance at both ends of the skeleton, so as to ensure that the skeleton will not sway when the vibration system is working, so that the vibration of the skeleton is stable and the sound quality is improved.
