Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing information handling systems face challenges in providing high-quality audio output without interference from display components, particularly when using front-firing speakers, which can be obstructed by the display's structure.
Innovation Solution
Incorporation of a halo display system with a first halo that transitions between positions and an exciter component using ceramic materials that contract and expand to generate sound, combined with a reflector plate to enhance sound performance and minimize interference.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-generated harmful factors
If front-firing speakers are used in the display, then audio output is provided, but the display structure obstructs and interferes with the sound
Solution Approach 1:
The display structure is segmented into functional zones: a display area for visual output and a separate audio area for sound generation. The halo component is positioned to define a distinct audio playback region that is spatially separated from the main display panel, allowing sound waves to propagate without interference from display components.
Solution Approach 2:
The audio channels are positioned in a different spatial dimension relative to the display panel. By utilizing the halo component and reflector plate, sound waves are directed through dedicated audio channels that extend away from the display structure, creating a three-dimensional sound propagation path that avoids obstruction from the display components.
2Object-generated harmful factors
If the halo is positioned to enable audio playback, then sound quality is improved, but the display area may be reduced
Solution Approach 1:
Different regions of the display structure are assigned different functional qualities. The halo component and reflector plate create a localized audio playback zone with specific acoustic properties, while the remaining area maintains full display functionality. This local differentiation allows high-quality audio without compromising overall display area.
Solution Approach 2:
The reflector plate acts as an intermediary element that directs and focuses sound waves from the audio channels toward the user. This intermediary component enables effective audio playback without requiring the halo to occupy significant display area, as the reflector plate efficiently channels the sound waves.

Function Achieved in This Case
The solution provides enhanced multi-channel sound quality by directing sound waves through dedicated audio channels, reducing interference from display components and improving overall audio output.
Implementation Method 1
The first exciter component includes first and second electrodes, and a ceramic component is in physical communication with and located between the first and second electrodes. When a voltage is applied to the first and second electrodes, the ceramic component may contract and expand. The contraction and the expansion of the ceramic component may generate sound from the first exciter.
