Loudspeaker Cone Diaphragm 3D Light Pattern
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional loudspeakers have a simple light pattern due to their illumination design, lacking a complex and three-dimensional illumination effect.
Innovation Solution
The loudspeaker incorporates a cone-shaped diaphragm and an LED light source positioned to reflect light at multiple points, creating a complex and three-dimensional light pattern through the interference of light reflections on the diaphragm's surface, with adjustable LED placement and reflective materials enhancing pattern sharpness and brightness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If a conventional illumination part with a light-emitting element is used, then the loudspeaker can be illuminated, but the light pattern is simple and lacks three-dimensional appearance
Solution Approach 1:
The patent applies dimensionality change by utilizing the cone-shaped three-dimensional surface of the diaphragm as a reflective surface. The LED light source is positioned to reflect light at multiple points on the conical surface, creating complex light patterns through the interference of reflections. This transforms a simple illumination into a three-dimensional light pattern that follows the contour of the diaphragm, achieving visual complexity without adding complex illumination structure.
2Illumination intensity
If multiple light-emitting elements are arranged to create complex patterns, then the light pattern complexity increases, but the device complexity and assembly difficulty increase
Solution Approach 1:
The patent extracts the pattern-forming function from the illumination source itself and transfers it to the diaphragm surface. Instead of using multiple light-emitting elements arranged in complex patterns, a single LED is used and the diaphragm's conical surface is utilized as the pattern-generating element through light reflection. This separates the light generation function from the pattern formation function, greatly simplifying assembly while maintaining complex light patterns.
Solution Approach 2:
The patent introduces the diaphragm surface as an intermediary between the LED light source and the observer. The conical surface of the diaphragm acts as a reflective mediator that transforms simple LED light into complex three-dimensional light patterns. This intermediary approach allows a simple light source to produce complex visual effects without requiring complex illumination structure or difficult assembly.
3Illumination intensity
If a ring-shaped illumination part is attached to the front face, then the loudspeaker can be illuminated, but the assembly process adds time and the structure becomes more complex
Solution Approach 1:
The patent merges the illumination function with the existing diaphragm structure. Instead of attaching a separate ring-shaped illumination part to the front face, the LED is integrated with the diaphragm assembly, using the diaphragm's own conical surface as the illumination display surface. This integration eliminates the need for separate attachment processes and reduces assembly time while maintaining the illumination function.
Solution Approach 2:
The patent makes the diaphragm serve multiple functions: it acts as both the sound-producing element and the illumination display surface. The conical surface of the diaphragm is utilized for both acoustic purposes and as a reflective surface for creating three-dimensional light patterns. This multi-functionality eliminates the need for separate illumination components and reduces overall assembly complexity and time.
