Solution Overview
Problem
Existing loudspeaker box light effects primarily focus on surface interactions, limiting the audio-visual experience due to weak interaction with the external space.

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If a lampshade on the surface of the loudspeaker box is used to present light effects, then the light source changes are visible on the surface, but the interaction with external space is weak and limited to a specific region
Solution Approach 1:
The patent transitions from surface-level light effects (2D) to spatial light beam projection (3D). By using condensing lenses to project light beams outward, the system extends illumination into the external space, creating light beams that can interact with objects and surfaces beyond the loudspeaker box surface, thereby enhancing spatial interaction and versatility.
Solution Approach 2:
The condensing lenses act as intermediaries between the light sources and the external space. These lenses concentrate and direct the light into focused beams, serving as a mediator that transforms the light output from a diffuse surface effect into a directed spatial projection, enabling enhanced interaction with the external environment.
2Adaptability or versatility
If multiple light sources are arranged in separate chambers with condensing lenses, then light beams can be projected to external surfaces enhancing spatial interactivity, but the device structure becomes more complex
Solution Approach 1:
The patent divides the light-emitting device into multiple independent chambers, each containing a light source and condensing lens assembly. This segmentation allows each chamber to function independently, projecting light beams in different directions or with different characteristics, thereby enhancing spatial interactivity while maintaining modular simplicity in each unit.
Solution Approach 2:
Each chamber module serves multiple functions: it contains the light source, the condensing lens for beam formation, and the partition structure for isolation. This multi-functional design reduces overall device complexity by integrating multiple components into unified modular units that can be replicated and arranged to achieve desired spatial light patterns.
