Slim Display Speaker Structure With Chamber Cushion Damping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display devices face challenges in improving sound quality, particularly mid-and high-pitched sound characteristics, and efficiently outputting sound from speakers due to slimming designs.
Innovation Solution
A display device structure incorporating a speaker with a speaker box, a plate covering the speaker unit, a chamber between the speaker unit and the plate, and a cushion occupying a portion of the chamber, which enhances sound output and quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of moving object
If the speaker thickness is reduced to match slim display device design, then the display device can achieve a thinner overall profile, but the sound quality particularly mid-and high-pitched sound characteristics deteriorate
Solution Approach 1:
The patent implements nesting by placing the speaker unit within a chamber formed between the speaker unit and the plate, creating a compact integrated structure. The cushion is nested within the chamber to provide damping without adding external volume, allowing the speaker to maintain thin profile while preserving acoustic performance through internal space utilization.
Solution Approach 2:
The patent applies local quality by introducing a cushion with specific acoustic properties into the chamber at a strategic location. This cushion provides localized damping and resonance control in the chamber space, improving mid-and high-pitched sound characteristics without requiring increased overall speaker thickness.
2Volume of moving object
If the speaker unit is tightly coupled to the speaker box to reduce size, then the display device achieves thinner profile, but sound output clarity and smoothness deteriorate
Solution Approach 1:
The plate serves as an intermediary element between the speaker unit and the speaker box. It provides a structured interface that facilitates controlled sound transmission while maintaining the compact integrated design. The chamber and cushion act as intermediary acoustic elements that smooth sound output without requiring additional volume.
Solution Approach 2:
The patent utilizes parameter changes by modifying the acoustic parameters within the chamber through the cushion material and chamber geometry. These parameter adjustments optimize sound transmission characteristics and clarity while maintaining a compact volume, allowing clear sound output without increased speaker size.
