Wax-Coated Speaker Shell for Resonance and Design Flexibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wooden speakers offer advantages in sound quality due to high density and excellent resonance, but they have poor aesthetics, limited shape changeability, and a slow manufacturing process, making them visually unappealing and monotonous.
Innovation Solution
A speaker design utilizing a waxy material as the main shell, which provides excellent resonance and changeability, with a supporting shell structure that includes multiple speaker monomers and a sound source circuit, and is covered with a high-density wax material that enhances sound vibration and allows for easy modification and design customization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If wooden material is used for speaker shell, then sound quality and resonance are improved, but appearance aesthetics and shape changeability deteriorate
Solution Approach 1:
The patent uses a composite structure combining wooden material (for acoustic performance) with other materials (for aesthetic and shaping flexibility). This allows the speaker to maintain the resonant properties of wood while achieving diverse shapes and better appearance through the composite construction.
2Reliability
If wooden material is used for speaker shell, then sound quality is improved, but manufacturing speed deteriorates
Solution Approach 1:
The speaker shell is divided into multiple segments or components that can be manufactured separately and then assembled. This segmentation allows parallel production of different parts, significantly reducing overall manufacturing time while maintaining the wooden material's acoustic benefits in critical areas.
3Ease of manufacture
If low-cost wooden speaker is used, then manufacturing cost is reduced, but appearance quality and shell thickness deteriorate
Solution Approach 1:
Different parts of the speaker shell have different material properties and thicknesses optimized for their specific functions. Critical acoustic areas use thicker wooden sections for resonance, while non-critical areas use thinner materials or different finishes for aesthetic purposes, achieving good appearance without uniformly increasing cost and thickness.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The speaker achieves a beautiful appearance, improved sound quality with enhanced resonance, and rapid manufacturing process, enabling versatile design options and a high-texture finish similar to a real candle.
Implementation Method 1
the wooden material is also superior to the plastic material in the reflection of the sound and the resonance of the sound
Implementation Method 2
the wooden material is also superior to the plastic material in the reflection of the sound and the resonance of the sound
Implementation Method 3
The density of the medium density fiberboard is uniform and its surface is smooth. Thus, the density value of the shell of the wooden speaker is usually large. Therefore, when a sound is spoken from the wooden speaker, the vibration of the wooden speaker is slight.
