Display Assembly Speaker Integration Without Losing Screen Area
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The challenge in gaming machines is integrating audio speakers effectively without obstructing the display devices, particularly when tall video displays or multiple smaller displays occupy the front-facing surfaces, leaving limited space for forward-facing speakers.
Innovation Solution
A display assembly that integrates audio speakers within the display device housing, using a front cover with speaker openings spaced from the peripheral edge and transparent areas, optionally with accent lighting, ensuring the speakers are not visible through the cover.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If forward facing audio speakers are placed in the gaming machine, then audio performance is improved, but the display area is reduced
Solution Approach 1:
The patent combines the audio speaker assembly with the display device housing, integrating the speaker into the display assembly structure. The speaker is positioned within the display housing and oriented to project sound forward through the display device, allowing both display and audio functions to coexist in the same space without conflicting for front-facing real estate.
Solution Approach 2:
The speaker assembly is positioned within the depth dimension of the display housing rather than occupying front-facing surface area. By utilizing the internal volume and positioning the speaker behind the display screen, the design transforms a two-dimensional surface space constraint into a three-dimensional volume utilization, allowing audio components to exist without reducing the visible display area.
2Area of stationary object
If audio speakers are integrated within the display assembly housing, then space utilization is improved, but speaker visibility through the front cover may occur
Solution Approach 1:
The front cover is designed with differentiated optical properties across its surface. Specific regions corresponding to the speaker assembly location are made opaque or translucent to block speaker visibility, while other regions remain transparent to allow display visibility. This local variation in optical quality allows the cover to simultaneously protect the integrated speaker and maintain aesthetic appearance.
Solution Approach 2:
The front cover acts as an intermediary element between the integrated speaker assembly and the external environment. It selectively transmits or blocks light depending on the underlying component, serving as a visual filter that hides the speaker while allowing the display to remain visible through transparent portions of the cover.

AI summary
A display assembly includes a display assembly housing, a display device, a front cover, and a first audio speaker assembly. The front cover is secured over an opening to a display assembly housing volume defined by the display assembly housing. The display device is mounted within the display assembly housing volume and defines a display device area aligning with a first area of the front cover. The display assembly further includes a first speaker opening in the front cover. The first speaker opening is defined by a first speaker opening peripheral edge that lies entirely within the front cover area so that the first speaker opening is spaced apart from the front cover peripheral edge. The first audio speaker assembly is mounted within the display assembly housing volume so that a sound output area of the first audio speaker assembly aligns with the first speaker opening in the front cover.
