Solution Overview
Problem
The design of display apparatuses with integrated speakers faces challenges due to space constraints, leading to degraded sound quality from interference with walls and floors, which reduces sound accuracy and immersion experience.
Innovation Solution
An apparatus that includes a vibration member and a vibration apparatus, where a supporting member with holes is used to connect the vibration apparatus to the rear surface of the vibration member, creating a sealed structure with a gas state that enhances vibration characteristics and directs sound forward, improving sound pressure and low-pitched sound band quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If a speaker is integrated into the display apparatus, then the space arrangement is optimized, but the sound quality is degraded due to interference with walls and floors
Solution Approach 1:
The patent extracts the harmful rearward sound propagation by introducing a sound blocking member that prevents sound from traveling backward toward walls and floors. This isolates the harmful sound path while preserving the forward sound output, thereby maintaining space efficiency while eliminating sound interference issues
Solution Approach 2:
The sound blocking member acts as an intermediary element between the speaker and the rear environment (walls/floors). It mediates the sound propagation by blocking harmful rearward paths while allowing the speaker to maintain its integrated position in the display apparatus
2Reliability
If a sealed structure with gas state is created between supporting member and vibration member, then air resistance decreases and vibration characteristics improve, but the structure complexity increases
Solution Approach 1:
The patent changes the physical state parameter of the internal space by maintaining a gas state (vacuum or inert gas) between the supporting member and vibration member. This parameter change reduces air resistance and improves vibration characteristics without requiring complex active control systems
Solution Approach 2:
The patent creates an inert environment (vacuum or gas-filled sealed space) between the supporting member and vibration member to eliminate air resistance. This inert atmosphere allows the vibration member to oscillate with minimal damping, improving sound output characteristics while using a relatively simple sealed structure
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 solution effectively enhances sound quality and sound pressure levels by directing sound forward and reducing air resistance, thereby improving the overall audio experience in display apparatuses.
Implementation Method 1
an internal space provided between a supporting member and a vibration member maintains a vibration state or a gas state which is good in compression/expansion rate, and thus, an air resistance of the internal space may decrease, thereby enhancing a vibration characteristic of the vibration member
Implementation Method 2
a vibration apparatus between the rear surface of the vibration member and the enclosure to vibrate the vibration member... maintains a vibration state or a gas state which is good in compression/expansion rate

AI summary
An apparatus includes a vibration member, a vibration apparatus configured to vibrate the vibration member, a supporting member at a rear surface of the vibration member with a first space therebetween, and an enclosure configuring a second space at a rear surface of the supporting member overlapping with the vibration apparatus. The first space may be connected with the second space.
