Speaker Mount Structure for Compact Vibration-Isolated Installation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing speaker devices are limited in miniaturization due to support structures that cover the entire circumference, restricting their size when viewed along the central axis.
Innovation Solution
A speaker device with a support mechanism that elastically supports the speaker unit using first and second fixing portions and a support portion, positioned between these, with an orthogonal alignment to the central axis, allowing for miniaturization and reduced vibration transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the speaker unit is supported over an entire circumference, then the speaker unit is stably supported, but miniaturization of the speaker device when viewed in a direction of a central axis is restricted
Solution Approach 1:
The support mechanism is divided into a first support member and a second support member that are positioned at different locations along the central axis direction. This segmentation allows the speaker unit to be supported at discrete points rather than continuously, reducing the overall device size while maintaining stability through distributed support points.
Solution Approach 2:
The support members are arranged in the central axis direction (vertical dimension) rather than only in the radial direction. This dimensional change allows the speaker unit to be compact in the radial direction while achieving stable support through vertical distribution of support members, enabling miniaturization when viewed along the central axis.
2Adaptability or versatility
If the speaker unit is miniaturized, then design flexibility is improved, but vibration and sound leakage may increase
Solution Approach 1:
A dust-proof sheet is introduced as an intermediary component between the speaker unit and the external environment. This thin flexible sheet acts as a barrier that prevents sound leakage and reduces vibration transmission to the mounting structure, while being thin enough to allow compact speaker unit design and not interfering with acoustic performance.
Solution Approach 2:
The dust-proof sheet serves as a flexible thin film that conforms to the speaker unit geometry. This flexible membrane provides acoustic sealing and vibration damping without adding significant volume, enabling miniaturization while controlling harmful vibrations and sound leakage.

AI summary
A speaker device includes a speaker unit, and a support mechanism elastically supporting the speaker unit with respect to an external structure. The support mechanism includes a first fixing portion configured to be fixed to the external structure, a second fixing portion configured to be fixed to the external structure, and a support portion that elastically couples the speaker unit to the first fixing portion and the second fixing portion. The speaker unit is positioned between the first fixing portion and the second fixing portion as viewed in a direction of a central axis of the speaker unit, and a straight line passing through the first fixing portion and the second fixing portion is orthogonal to the central axis of the speaker unit.
