Loudspeaker Box Floating Display via Translucent Panel
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional loudspeaker boxes with integrated displays face challenges of complex structural assembly, high cost, poor sound quality, large size, and heavy weight due to the coexistence of speakers and display units on the front side.
Innovation Solution
A loudspeaker box design featuring a housing with a first transparent plate on the front and a second transparent plate on the rear, embedding a speaker in the first plate and a translucent liquid crystal panel with a backlight module in the housing, along with a control circuit and rechargeable battery, creating a floating display effect and enhancing sound quality with AI voice control and wireless audio capabilities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the display unit and speaker are both located on the front side of the loudspeaker box, then the display function and sound output function are achieved, but the structural assembly becomes complicated, resulting in high cost, poor sound quality, large size and heavy weight
Solution Approach 1:
The display unit is moved from the front side to the rear side of the loudspeaker box, changing its spatial position from the same plane as the speaker to a different plane. This dimensional repositioning allows the display and speaker to coexist without interfering with each other's performance, simplifying the overall structure while maintaining both functions.
Solution Approach 2:
The loudspeaker box is divided into distinct functional zones: the front side houses the speaker for optimal sound output, while the rear side accommodates the display unit. This segmentation separates the audio function from the visual function, allowing each component to be optimized independently without compromising the other.
2Adaptability or versatility
If the display unit and speaker are both located on the front side of the loudspeaker box, then the display function and sound output function are achieved, but the sound quality deteriorates
Solution Approach 1:
By relocating the display unit to the rear side of the loudspeaker box, the acoustic path of the speaker is no longer obstructed by the display components. This spatial separation in different dimensions ensures that the speaker can operate without interference, maintaining high sound quality while still providing display functionality.
3Adaptability or versatility
If the display unit and speaker are both located on the front side of the loudspeaker box, then the display function and sound output function are achieved, but the size and weight increase
Solution Approach 1:
The display unit is repositioned to the rear side of the loudspeaker box, utilizing the available space in the depth dimension rather than expanding the front surface area. This allows for a more compact overall design that reduces both the size and weight of the loudspeaker box while maintaining dual functionality.

Implementation Method 1
a backlight module matched with a back of the translucent liquid crystal panel at intervals
Implementation Method 2
a translucent liquid crystal panel arranged behind the first speaker
Implementation Method 3
the light guide plate is illuminated from the edge by the light-emitting circuit board, so that the light guide plate forms a surface light source that emits light evenly
Implementation Method 4
a first speaker embedded in the first transparent plate

AI summary
Disclosed is a loudspeaker box with floating display including a housing, a first transparent plate arranged on front side of the housing, a second transparent plate arranged on rear side of the housing, a first speaker embedded in the first transparent plate, and a display module and a control circuit arranged in the housing. The display module includes a translucent liquid crystal panel arranged behind the first speaker and a backlight module matched with a back of the translucent liquid crystal panel at intervals. The display module of the invention displays lyrics and background through a translucent liquid crystal panel arranged behind the first speaker to create a display effect hidden behind the first transparent panel, and the translucent liquid crystal panel is matched with the backlight module at intervals, so that a display content of the translucent liquid crystal panel has a floating three-dimensional effect in naked eye vision.
