Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing speaker lamps compromise on sound quality and lighting efficiency due to the space occupied by the speaker within the light diffuser, affecting both sound and lighting performance.
Innovation Solution
A speaker lamp design featuring a housing with a cavity divided by a radiator, a circuit board with LED light sources, and a reflector that surrounds the speaker, creating a resonance cavity and improving lighting efficiency while allowing sound transmission through an opening, with a sealed structure to maximize sound cavity volume.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the speaker is installed within the light transmitting diffuser, then the speaker lamp can be formed as a simple combination, but the lighting effect is affected and sound quality is compromised
Solution Approach 1:
The patent divides the internal space into distinct functional zones: the light cavity for LED illumination and the resonance cavity for speaker sound output. The reflector acts as a spatial separator, directing light while allowing sound transmission through the opening, thus resolving the conflict between simple integration and functional performance.
2Volume of stationary object
If the speaker occupies space within the light transmitting diffuser, then the overall structure is compact, but the sound quality and lighting efficiency are compromised
Solution Approach 1:
The patent utilizes the vertical dimension by extending the resonance cavity downward from the speaker, while the light cavity occupies the upper portion. This dimensional separation allows both lighting and sound functions to operate independently without compromising each other, maintaining compact overall size while ensuring sound quality.
3Device complexity
If the speaker occupies space within the light transmitting diffuser, then the structure is integrated, but the lighting efficiency is affected
Solution Approach 1:
The patent extracts the speaker from the light transmitting diffuser space and places it in a dedicated resonance cavity. The reflector with its opening allows the speaker to be positioned below the light cavity, separating the light path from the sound path and eliminating the negative impact on lighting efficiency while maintaining integration.
4Reliability
If a sealed cavity is formed, then the resonance cavity volume is maximized for better sound effect, but the space utilization becomes constrained
Solution Approach 1:
The patent nests the resonance cavity within the overall housing structure, with the light cavity positioned above and the speaker accommodated within the reflector cavity. This nested arrangement maximizes the use of available vertical space, allowing the sealed resonance cavity to achieve optimal volume for sound quality without excessive overall size.
