Linear Vibrator Suspension Design for Rapid Vibration Transmission
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Typical linear vibrators face challenges in rapidly transmitting vibrations to outside components and have an increased height, which affects their efficiency and design.
Innovation Solution
The design includes a suspension system with a flat part, a connecting portion bent downward, and a spring portion extended horizontally, allowing direct connection to outside components and reducing the overall height by dividing the suspension into two parts for improved vibration transmission and support.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If a typical linear vibrator uses a cover directly connected with the outside component and a plate suspension, then the structure is simple, but the vibration transmission speed is slow and the height is increased
Solution Approach 1:
The suspension is divided into multiple functional parts: a flat part for direct connection with the oscillating portion, a connecting portion bent downward to reduce height, and a spring portion for elastic support. This segmentation allows each part to optimize its function, enabling rapid vibration transmission while reducing overall height.
Solution Approach 2:
The connecting portion is bent downward in a vertical direction, transitioning the suspension structure from a purely horizontal layout to a three-dimensional configuration. This dimensional change allows the suspension to connect the oscillating portion directly while reducing the height occupied by the linear vibrator.
2Productivity
If the suspension is designed as a single plate structure, then the manufacturing is simple, but the vibration transmission efficiency is reduced
Solution Approach 1:
The suspension is segmented into distinct functional zones: a flat part for rigid connection and vibration transmission, a connecting portion for spatial transition, and a spring portion for elastic support. This segmentation improves vibration transmission efficiency by optimizing each zone's mechanical properties while maintaining manufacturability.
Solution Approach 2:
Different parts of the suspension have different structural qualities optimized for their specific functions: the flat part provides rigid connection for efficient vibration transmission, the connecting portion provides spatial transition, and the spring portion provides elastic compliance. This local differentiation enhances overall performance without excessive complexity.

AI summary
The linear vibrator includes a base forming a hollow space, a suspension fixed on the base, and an oscillating portion suspended in the hollow space by the suspension. The suspension defines a flat part, a connecting portion bent downward from the flat part, and a spring portion extended horizontally in a direction parallel to flat part from the end of the connecting portion. The suspension is directly connected with the outside component, thereby transmitting the vibration to the outside component rapidly.
