Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing vibration output apparatuses face challenges in maintaining the strength and stability of the exciter due to the use of soft cushions, which can lead to instability and degradation over time, while hard cushions compromise the quality of low-frequency acoustic vibrations.

Innovation Solution

A vibration output apparatus with a vibration transmission member that integrates a body plate and support portions, where the exciter is supported by the body plate and not directly by the cushion, allowing for a soft cushion to be used without risking instability, and enabling the absorption of unwanted frequency components for improved low-frequency vibration output.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the cushion is formed of a soft material, then the acoustic vibration output quality is improved, but the strength to hold the exciter deteriorates

Engineering Contradiction:

Improveacoustic vibration output qualityVSAvoidstrength to hold the exciter

Core Design Contradiction:

ReliabilityVSStrength

Solution Approach 1:

The support structure is segmented into a vibration transmission member (with body plate and support portions) and a cushion. The exciter is supported by the rigid vibration transmission member while the cushion is positioned separately to absorb unwanted frequency components, allowing each component to perform its specialized function without compromise

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The vibration transmission member acts as an intermediary between the exciter and the cushion. It transmits the exciter's vibrations to the cushion while maintaining secure support of the exciter, allowing the soft cushion to perform its vibration absorption function without compromising exciter stability

Inventive Principle:

Principle #24Intermediary (Mediator)

2Strength

If the cushion is formed of a hard material, then the strength to hold the exciter is improved, but the acoustic vibration output quality deteriorates

Engineering Contradiction:

Improvestrength to hold the exciterVSAvoidacoustic vibration output quality

Core Design Contradiction:

StrengthVSReliability

Solution Approach 1:

The support system is divided into two functional parts: the rigid vibration transmission member that provides structural support and the soft cushion that optimizes acoustic vibration output. This segmentation allows each component to be optimized for its specific function without the trade-offs of a single-material solution

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Different parts of the support structure have different material properties optimized for their specific functions: the vibration transmission member uses rigid material for structural support, while the cushion uses soft material for vibration absorption and acoustic optimization, allowing each location to have the quality needed for its purpose

Inventive Principle:

Principle #3Local quality

3Ease of operation

If the cushion is used to support the exciter, then the ease of mounting is improved, but the stability over time deteriorates due to degradation

Engineering Contradiction:

Improveease of mountingVSAvoidstability over time

Core Design Contradiction:

Ease of operationVSStability of the object's composition

Solution Approach 1:

The vibration transmission member is designed with integrated support portions that provide stable, long-term support for the exciter. The cushion is positioned to absorb vibrations rather than bear the exciter's weight, protecting the mounting system from degradation over time while maintaining ease of assembly

Inventive Principle:

Principle #11Beforehand cushioning (Prior cushioning)

Solution Approach 2:

The vibration transmission member serves as a stable intermediary structure that maintains consistent geometric support for the exciter over time, while the cushion provides vibration isolation. This separation ensures long-term stability is not compromised by cushion material degradation

Inventive Principle:

Principle #24Intermediary (Mediator)

Function Achieved in This Case

This configuration ensures the exciter remains stable and securely mounted, even with soft cushions, and maintains the quality of low-frequency vibrations by isolating the cushion's degradation effects, providing deep and extended bass without distortion.

AI summary

A vibration output apparatus (1) includes a vibration transmission member (20), an acoustic vibration output unit (10), and a cushion (30). The vibration transmission member (20) is formed by integrating a body plate (21) and a support portion (22). The support portion (22) is in contact with a vibration plate (100) and supports the body plate (21). The body plate (21) has an opposite surface (21a) opposite to a vibration surface (100u) of the vibration plate (100) and forms an opposite space (S1) between the vibration surface (100u) and the opposite surface (21a). The acoustic vibration output unit (10) is disposed on a rear surface (21b) of the opposite surface (21a) of the body plate (21) and is configured to output an acoustic vibration. The support portion (22, 23) is not in contact with the cushion (30).
