Microphone-Hidden Speaker Structure with Decorative Cover Plate
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current speakers with microphones lack aesthetic appeal due to exposed microphone cavities and pose safety risks as children can easily access and damage the microphones.
Innovation Solution
A microphone-hidden speaker structure featuring a housing with an inwardly extending microphone cavity, a decorative cover plate made of soft or hard material with snap-fitting and magnetic attachment mechanisms, and a flexible buffer pad to securely hide and protect the microphone.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If the microphone accommodating cavity is formed on the housing surface without a decorative cover plate, then the structure is simple and easy to manufacture, but the overall flatness and aesthetics are poor
Solution Approach 1:
The housing surface is segmented into functional areas: the microphone accommodating cavity is separated from the main housing surface by forming it as a distinct recessed structure, allowing independent treatment of aesthetic and functional requirements
Solution Approach 2:
The decorative cover plate is nested over the microphone accommodating cavity, creating a layered structure where the cover plate conceals the cavity while the cavity provides functional accommodation, thus improving aesthetics without compromising simplicity
2Reliability
If the microphone is placed in an open accommodating cavity, then the structure is simple and accessible, but children can easily access, remove, or damage the microphone
Solution Approach 1:
The decorative cover plate serves as an intermediary element between the external environment and the microphone. It provides physical protection and prevents direct access by children, while still allowing authorized users to remove it for microphone access through the detachable connection mechanism
Solution Approach 2:
The detachable connection mechanism (snap-fitting or magnetic) allows the decorative cover plate to transition between fixed and removable states. This dynamic特性 enables the system to switch between protected mode (preventing child access) and accessible mode (allowing user maintenance)
3Strength
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:
A flexible buffer pad is introduced between the hard decorative cover plate and the housing. This flexible element acts as a vibration isolator, absorbing resonance forces and preventing the transmission of vibration from the housing to the cover plate, thus eliminating the harmful resonance noise while maintaining the durability of the hard cover plate material
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
Enhances aesthetics, reduces noise, and provides easy access for users to store or remove the microphone while preventing damage by children through secure and quick attachment of the decorative cover plate.
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 rubber pads protrude from the side edge of the annular snap-fitting stand... such that quick mounting and fixation of the decorative cover plate are realized
Implementation Method 3
the speaker main body further includes a first magnetic attraction piece arranged on a side edge close to the microphone accommodating cavity; the decorative cover plate is provided with a second magnetic attraction piece... and the decorative cover plate is fixed on the housing through the first magnetic attraction piece and the second magnetic attraction piece
