Speaker Magnetic Circuit Limiting Structure for Impact Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Speakers in mobile electronic devices suffer from poor structural stability when subjected to impact forces, leading to inadequate control over the magnetic circuit system's movement, resulting in irreversible tearing or damage to damping components.
Innovation Solution
A speaker design featuring a limiting assembly between the upper clamping plate and damping component, with protrusions and concave grooves, and a magnetic circuit system with specific configurations to limit excessive movement, enhancing structural stability and preventing damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a damping component is connected to a mounting frame and magnetic circuit system, then shock resistance is enhanced, but structural stability deteriorates when subjected to impact forces
Solution Approach 1:
The mounting structure is divided into multiple components: mounting bracket, upper clamping plate, lower clamping plate, and limiting assembly. Each segment performs a specific function - the bracket provides mounting, clamping plates secure the damping component, and the limiting assembly controls movement. This segmentation allows each part to be optimized for its specific function while working together to solve the overall contradiction between shock resistance and structural stability.
Solution Approach 2:
The limiting assembly is pre-installed between the upper clamping plate and the damping component before impact occurs. The protrusions and concave grooves are pre-positioned to engage with each other, creating a predetermined movement limitation mechanism that activates automatically during impact, preventing excessive movement before it can cause structural instability.
2Reliability
If the magnetic circuit system is allowed to move freely during impact, then shock absorption is improved, but component damage increases due to excessive movement
Solution Approach 1:
The limiting assembly acts as an intermediary mechanism between the upper clamping plate and the damping component. It mediates the interaction by providing controlled engagement through protrusions and concave grooves, allowing the magnetic circuit system to move within safe limits during impact while preventing movement that would cause component damage. This intermediary structure enables both impact absorption and component protection simultaneously.

AI summary
A speaker and a speaker box are provided. The speaker includes a frame, a vibration system, and a magnetic circuit system. The vibration system is fixed to the frame, the magnetic circuit system is configured to drive the vibration system to vibrate. The magnetic circuit system includes a damping component, an upper clamping plate, a lower clamping plate, and a mounting bracket. A limiting assembly is disposed between the upper clamping plate and the top portion of the damping component. The speaker improves stability of structural installation between the upper clamping plate and the damping component, thereby improving mounting stability and mounting reliability of the magnetic circuit system and avoiding irreversible tearing or impact damage to components, such as the damping component, etc., due to excessive movement of the magnetic circuit system.
