Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing loudspeaker cover plates made of plastic have poor touch and texture, reducing the attractiveness and user experience of sound boxes.
Innovation Solution
A loudspeaker cover plate with a leather appearance piece and substrate, featuring through holes, improves touch and texture by using leather material and a flexible layer, enhancing sound permeability and aesthetic appeal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a plastic material is used for the loudspeaker cover plate, then the manufacturing cost is low and ease of manufacture is good, but the touch feeling and texture are poor
Solution Approach 1:
The patent applies composite materials by combining a plastic substrate with a leather appearance piece. The substrate provides structural support and ease of manufacture, while the leather appearance piece provides superior touch feeling and texture. This composite structure resolves the contradiction by integrating the advantages of both materials.
Solution Approach 2:
The patent applies local quality by using different materials for different parts of the loudspeaker cover plate. The substrate is made of plastic for structural integrity and ease of manufacture, while the appearance piece is made of leather for enhanced touch feeling and aesthetic appearance. Each part is optimized for its specific function.
2Ease of manufacture
If a plastic material is used for the loudspeaker cover plate, then the manufacturing cost is low, but the texture and aesthetics are poor
Solution Approach 1:
The patent uses composite materials to combine the cost-effectiveness of plastic with the aesthetic appeal of leather. The plastic substrate remains economical to manufacture while the leather appearance piece provides the desired texture and visual appeal, achieving a balance between cost and aesthetics.
Solution Approach 2:
The patent applies local quality by restricting the leather material to only the appearance piece where aesthetic properties are needed, while the substrate remains plastic for cost efficiency. This localized application of different materials optimizes both manufacturing cost and texture quality.
3Reliability
If through holes are added to the cover plate, then sound permeability is improved, but the structural strength is reduced
Solution Approach 1:
The patent applies segmentation by dividing the cover plate into a substrate and an appearance piece, with through holes positioned in specific segments. This allows sound to pass through while maintaining structural integrity in other areas, balancing sound permeability and strength.
Solution Approach 2:
The patent applies local quality by strategically positioning through holes in the appearance piece rather than uniformly distributing them throughout the entire cover plate. This localized approach maintains structural strength in critical areas while allowing sound permeability where needed.

AI summary
The present disclosure provides a loudspeaker cover plate, a sound playing apparatus and a terminal. The loudspeaker cover plate includes a substrate and an appearance piece covering the substrate. The substrate is configured to connect to a loudspeaker. The appearance piece is located on a surface of the substrate away from the loudspeaker. A plurality of first through holes are arranged on the substrate, a plurality of second through holes are arranged on the appearance piece, and at least some of the second through holes are opposite to the first through holes. A forming material of the appearance piece is a leather material. The material of the leather appearance piece is soft, so that the hardness of the loudspeaker cover plate may be effectively reduced, and good touch experience may be brought to a user during touch, thereby effectively improving the touch feeling of the loudspeaker cover plate.
