Solution Overview

Problem

Conventional speakers face a space constraint due to the need for a thick elastic body to block vibrations, requiring changes in attachment methods and structures, which is not feasible in all scenarios.

Innovation Solution

A speaker design incorporating a thin plate elastic body interposed between the speaker unit and attachment member, aligned with the vibration direction of the diaphragm, allowing for effective vibration isolation without altering the conventional attachment method or structure.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a conventional elastic body is used to block vibration transmission, then vibration-proof effect is achieved, but space is consumed due to required thickness

Engineering Contradiction:

Improvevibration-proof effectVSAvoidspace

Core Design Contradiction:

ReliabilityVSVolume of moving object

Solution Approach 1:

The patent applies this principle by using a thin plate structure elastic body instead of a thick conventional elastic body. The thin plate elastic body maintains vibration isolation functionality while significantly reducing the thickness and space required, directly resolving the contradiction between vibration-proof effect and space consumption.

Inventive Principle:

Principle #30Flexible shells and thin films

Solution Approach 2:

The patent changes the physical parameters of the elastic body by transitioning from a thick compression-based structure to a thin plate bending structure. This parameter change allows the elastic body to achieve comparable vibration isolation performance with dramatically reduced thickness, solving the space problem while maintaining reliability.

Inventive Principle:

Principle #35Parameter changes

2Reliability

If an elastic body is interposed between speaker unit and attachment object, then vibration transmission is blocked, but attachment method and structure must be changed

Engineering Contradiction:

Improvevibration-proof effectVSAvoidattachment method and structure

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent segments the attachment system into three distinct components: the speaker unit, the thin plate elastic body, and the attachment member. This segmentation allows each component to perform its specific function independently, enabling vibration isolation without requiring changes to the speaker unit or attachment object structures.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The thin plate elastic body serves as an intermediary element between the speaker unit and the attachment member. It provides the vibration isolation function while allowing both the speaker unit and attachment member to maintain their conventional structures, thus avoiding the need to change attachment methods or structures.

Inventive Principle:

Principle #24Intermediary (Mediator)

3Volume of moving object

If thin plate elastic body is used, then space is saved, but vibration isolation performance may be compromised

Engineering Contradiction:

ImprovespaceVSAvoidvibration-proof effect

Core Design Contradiction:

Volume of moving objectVSReliability

Solution Approach 1:

The thin plate elastic body utilizes dynamic bending deformation to absorb and dissipate vibration energy. By aligning the plate thickness direction with the vibration direction of the diaphragm, the structure dynamically responds to vibrations, providing effective isolation despite the reduced thickness.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The patent changes the dimension of elastic deformation from compression (thickness direction in conventional bodies) to bending (in-plane direction in thin plates). This dimensional change allows the thin plate structure to achieve comparable vibration isolation performance with much reduced thickness, resolving the contradiction between space and performance.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

AI summary

A speaker includes a speaker unit having a diaphragm, an attachment member attached to an attachment object of the speaker unit, and an elastic body interposed between the speaker unit and the attachment member. The elastic body has a thin plate structure and connects the speaker unit and the attachment member at both ends of the elastic body in a state where a plate thickness direction is aligned with a vibration direction of the diaphragm.
