Vibration Motor Elastic Component Damping Integration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional vibration motors compromise on weight and vibration performance due to the need for a damping block, which occupies space and affects the overall weight and functionality of the device.
Innovation Solution
The vibration motor incorporates an elastic component with a damping member integrated into its deforming portion, allowing for adjustable damping characteristics without increasing the weight, using a unique arrangement of magnets and coils to enhance electromagnetic induction efficiency and stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a damping block is arranged between the elastic component and the vibrator, then damping property of the vibrator is adjusted, but total weight of the vibrator increases and installation space is occupied
Solution Approach 1:
The damping member is integrated into the deforming portion of the elastic component, merging the damping function with the elastic support structure. This eliminates the need for a separate damping block, thereby reducing total weight while maintaining damping performance.
Solution Approach 2:
The deforming portion of the elastic component serves multiple functions: it provides elastic support for the vibrator and simultaneously incorporates the damping member to adjust damping characteristics. This multi-functionality reduces the number of separate components needed.
2Reliability
If a damping block is arranged between the elastic component and the vibrator, then damping property of the vibrator is adjusted, but installation space is occupied affecting vibration performance
Solution Approach 1:
The damping member is integrated into the deforming portion of the elastic component, merging the damping function with the elastic support structure. This eliminates the need for a separate damping block, thereby reducing total weight while maintaining damping performance.
Solution Approach 2:
The damping member is nested within the deforming portion of the elastic component, utilizing the existing structural space rather than requiring additional installation space. This nesting approach maintains compact design while achieving damping functionality.

AI summary
A vibration motor, including: a shell having accommodating space, a driving device accommodated in the accommodating space, a vibrator, and an elastic component elastically supporting the vibrator; the elastic component includes a first fixing portion connected with the shell, a second fixing portion connected with the vibrator, and a deforming portion connecting the first fixing portion with the second fixing portion; the deforming portion includes at least two elastic arms and a bending portion connecting two adjacent elastic arms, the fixing portions move close to or away from each other under compression or stretching of the deforming portion, so that the vibrator vibrate along vibrating direction, a damping member is arranged at inner surface of the bending portion close to the two adjacent elastic arms. The present disclosure adopts a new elastic component, which can adjust system damping property while guaranteeing vibrator weight, so as to improve vibration performance.
