Vibrating Subsidiary Area Sound Generator for Display Panel
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional display devices face challenges in providing an unobstructed wider display area while maintaining sound output, as traditional sound generators often require external exposure for functionality.
Innovation Solution
The display device incorporates a sound generator system where multiple sound generators are disposed on the inner surfaces of subsidiary areas of the display panel, connected through connection films, and driven by a single sound driving circuit, allowing for improved sound pressure and reduced circuit complexity, enabling stereo sound without external exposure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If traditional sound generators are exposed to the outside for sound output, then sound functionality is achieved, but the display area is reduced and the design is limited
Solution Approach 1:
The patent merges the sound generator with the display panel structure by disposing the sound generator on the inner surface of the subsidiary area, causing the display panel itself to vibrate for sound output. This integration eliminates the need for separate external sound generators, thereby maximizing the display area while maintaining sound functionality.
Solution Approach 2:
The patent transitions the sound generator from a traditional external component to an integrated component on the inner surface of the display panel. By utilizing the subsidiary area's inner surface and causing the display panel to vibrate, the sound output function is achieved within the existing display structure without requiring external exposure, thus expanding the display area.
2Reliability
If multiple sound generators are used to improve sound pressure, then sound output quality is enhanced, but the device complexity increases
Solution Approach 1:
The patent combines multiple sound generators (first and second sound generators) into a unified system controlled by a single sound driving circuit. The connection films integrate the electrical connections of multiple sound generators to one driving circuit, achieving improved sound pressure and stereo sound while avoiding the complexity of multiple independent driving circuits.
Solution Approach 2:
The single sound driving circuit serves multiple functions by controlling both the first and second sound generators. This universal circuit design enables the system to achieve enhanced sound output quality and stereo sound effects without requiring separate dedicated circuits for each sound generator, thereby reducing overall device complexity.
3Area of stationary object
If sound generators are disposed on subsidiary areas, then the display area is expanded, but the sound pressure may be reduced
Solution Approach 1:
The patent merges multiple sound generators on the inner surface of the subsidiary area to collectively enhance sound pressure. By disposing both the first and second sound generators on the subsidiary area and connecting them through connection films to a single driving circuit, the system achieves improved sound pressure and stereo sound while maintaining the expanded display area.
Solution Approach 2:
The patent utilizes the inner surface of the subsidiary area as a new dimension for sound generator placement. This spatial arrangement allows multiple sound generators to be positioned without occupying additional external space, thereby maintaining the expanded display area while achieving enhanced sound pressure through the combined vibration of multiple generators and the display panel.
