Speaker Bend Ring Vertical Extension
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Speakers face a challenge in achieving a large effective vibration area while maintaining a small size, which affects their sensitivity due to the trade-off between size reduction and vibration area.
Innovation Solution
The speaker design incorporates a bend ring structure with an arc portion and outer brim connected to a bracket, where the outer brim extends downward to maximize the effective vibration area without exceeding the outer diameter limit, using materials like rubber or polyurethane, and optionally includes a damper and magnetic circuit system.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the speaker size is reduced to meet consumer demand for lighter, thinner, and smaller speakers, then the portability and aesthetics are improved, but the effective vibration area is reduced leading to decreased sensitivity
Solution Approach 1:
The patent applies dimensionality change by extending the outer brim of the bend ring vertically downward to connect with the bracket, utilizing the vertical dimension to maximize the effective vibration area. This allows the speaker to achieve a larger vibration area without increasing the horizontal footprint, thus resolving the contradiction between small speaker size and large effective vibration area.
2Area of moving object
If the outer brim of the bend ring is extended downward to maximize effective vibration area, then the sensitivity is improved, but the structural complexity increases
Solution Approach 1:
The outer brim of the bend ring serves multiple functions: it extends downward to connect with the bracket, provides structural support, and maximizes the effective vibration area. By making this single component multi-functional, the patent avoids adding separate structural elements that would increase overall complexity while still achieving the goal of maximizing vibration area.
Solution Approach 2:
The patent merges the connection function and the vibration area maximization function into a single structural feature - the downward-extending outer brim of the bend ring. This integration eliminates the need for separate connection mechanisms and maximizes the effective vibration area simultaneously, reducing overall structural complexity.

AI summary
A speaker having a support structure having a bracket, and a vibration structure having a bend ring. The bend ring comprises an arc portion and an outer brim connected to the bracket. The outer brim of the bend ring extends downwardly to abut and connect to an outer brim of the top of the bracket, and the outer brim of the bend ring does not exceed the outermost end of the arc portion in the radial direction. The effective vibration area of a speaker is increased by using the above structure, so that the sensitivity of the speaker is improved.
