Microphone-Hidden Speaker Structure with Recessed Detachable Cover
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current speakers with microphones have poor aesthetics due to exposed microphone accommodating cavities lacking decorative cover plates, and the microphones are accessible to children, posing a risk of damage or misuse.
Innovation Solution
A microphone-hidden speaker structure with an inwardly extending cavity and a detachable decorative cover plate made of soft or hard material, secured via snap-fitting or magnetic attraction, which covers the microphone cavity to enhance aesthetics and prevent access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the microphone accommodating cavity is formed on the housing surface without a decorative cover plate, then the microphone is easily accessible for children to take out or damage, but the overall flatness and aesthetics of the speaker are poor
Solution Approach 1:
The decorative cover plate is embedded into the microphone accommodating cavity, creating a nested structure where the cover plate fits within the cavity opening. This nesting approach maintains the overall flatness of the speaker housing while providing a protective layer over the microphone, resolving the contradiction between protection and aesthetics.
Solution Approach 2:
The microphone accommodating cavity extends inwards from the housing surface with a certain depth, transitioning the microphone placement from a surface-level exposed position to a recessed three-dimensional space. This dimensional change allows the decorative cover plate to flush with the housing surface while the microphone remains protected inside the cavity.
2Strength
If the decorative cover plate is made of hard material, then the structure is durable, but resonance between the cover plate and housing increases when audio plays
Solution Approach 1:
The decorative cover plate is made of soft material with certain elasticity instead of hard material. This flexible property allows the cover plate to absorb vibrations and reduce resonance noise when audio plays, while still maintaining durability through the elastic material properties.
Solution Approach 2:
The solution employs composite material strategy by using soft elastic material for the decorative cover plate, combining the benefits of durability with vibration damping properties. The soft material acts as a vibration isolator between the housing and the external environment, reducing resonance while maintaining structural integrity.
3Ease of operation
If the decorative cover plate is detachably connected to the housing, then users can easily store or retrieve the microphone, but the connection structure becomes more complex
Solution Approach 1:
The connection between the decorative cover plate and housing is achieved through magnetic attraction between magnetic pieces embedded in both components, replacing complex mechanical fastening systems. This magnetic connection provides easy detachability for microphone access while maintaining a simple and clean structural design.
Solution Approach 2:
The magnetic connection system allows the decorative cover plate to be easily attached and detached by users without requiring tools or complex manipulation. The magnetic attraction automatically holds the plate in place during normal use, while allowing simple separation when needed, making the system self-servicing and user-friendly.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The structure improves aesthetics, reduces noise, and ensures easy access to the microphone while preventing damage by covering the microphone cavity with a decorative cover plate that minimizes resonance and is easily removable.
Implementation Method 1
the rubber pads on the side edge of the annular snap-fitting stand are squeezed and deformed to contact with the inner side wall of the microphone accommodating cavity
Implementation Method 2
the decorative cover plate is provided with a second magnetic attraction piece, the first magnetic attraction piece and the second magnetic attraction piece are opposite each other, and the decorative cover plate is fixed on the housing through the first magnetic attraction piece and the second magnetic attraction piece
