Display Panel Sound-Generating Device Partition Structure
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional display apparatuses face issues with sound quality due to speakers being positioned below or behind the display panel, leading to sound disruption and interference with surrounding surfaces, which detracts from the user's immersive experience and compromises sound quality.
Innovation Solution
A display apparatus with a sound-generating device integrated into the rear surface of the panel, utilizing a partition structure to direct sound forward, enhancing sound quality by minimizing interference and improving sound directivity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-generated harmful factors
If a speaker is provided in the display apparatus, then sound can be supplied, but the sound advances toward the lower or rear portion instead of the front portion, disrupting user immersion and deteriorating sound quality
Solution Approach 1:
The patent inverts the conventional speaker placement by positioning the sound-generating device on the front surface of the display panel rather than the rear or lower portion. This inversion allows sound to propagate directly toward the user in the forward direction, eliminating the need for sound to travel backward or downward, thereby resolving the contradiction between sound quality and user immersion experience
Solution Approach 2:
The patent changes the spatial dimension of sound propagation by transitioning from rearward or downward sound emission to forward-facing sound emission. The sound-generating device is oriented to emit sound in the forward direction (toward the user) rather than in the traditional rearward direction, effectively utilizing a different spatial dimension for sound propagation to improve both sound quality and user immersion
2Object-generated harmful factors
If a speaker is provided in the display apparatus, then sound can be supplied, but sound quality is deteriorated due to interference with sound reflected on the wall or floor
Solution Approach 1:
The patent extracts the sound-generating device from the conventional rear or lower position and relocates it to the front surface of the display panel. This extraction from the problematic position eliminates the source of sound reflection interference with walls or floor, thereby improving sound quality reliability by preventing the harmful reflection effect at its origin
Solution Approach 2:
The patent applies preliminary anti-action by positioning the sound-generating device to emit sound forward before any potential reflection interference can occur. By directing sound toward the user from the front surface, the system preemptively prevents sound from traveling to walls or floor and reflecting back, thus counteracting the harmful effect before it can manifest
3Object-generated harmful factors
If a speaker is included in a set apparatus, then sound can be supplied, but the speaker occupies space that imposes restriction on design and spatial disposition
Solution Approach 1:
The patent merges the sound-generating device with the display panel by positioning it on the front surface, integrating two functions (display and sound generation) into a unified structure. This merging eliminates the need for separate speaker spaces in the rear or lower portions, thereby reducing space occupation and design restrictions while maintaining both display and audio capabilities
Solution Approach 2:
The patent applies multi-functionality by making the display panel serve dual purposes: as the display surface and as the mounting location for the sound-generating device. The front surface of the display panel becomes a universal interface that supports both visual output and audio generation, reducing the need for additional dedicated spaces and simplifying the overall device design
