Solution Overview
Problem
Current microphone attachments fail to effectively reduce background noise during recordings, especially in unprocessed environments, leading to distorted sounds and ambient noise interference, which requires costly and complex room modifications to mitigate.
Innovation Solution
A portable microphone attachment made of high-quality metal with a curved foam structure and hollow cavity design that reduces background noise by attenuating unwanted sounds, allowing for stable microphone positioning and easy transport.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If room processing is implemented to reduce background noise, then noise reduction effectiveness is improved, but cost and complexity increase
Solution Approach 1:
The noise reduction function is extracted from the room environment and concentrated into a portable microphone attachment device. The attachment includes a housing with acoustic absorption material and a windscreen that can be attached to the microphone, removing the need for complex room processing while achieving similar noise reduction effects.
Solution Approach 2:
The microphone attachment acts as an intermediary between the microphone and the noisy environment. The housing with acoustic absorption material and windscreen serves as a mediator that filters out background noise and wind interference before the sound reaches the microphone, resolving the contradiction by providing noise reduction without requiring room modifications.
2Object-affected harmful factors
If room processing is implemented to reduce background noise, then noise reduction effectiveness is improved, but cost increases
Solution Approach 1:
The expensive room processing requirements are extracted and replaced with an affordable portable attachment. The microphone attachment uses cost-effective materials like foam acoustic absorption material and fabric windscreens, providing similar noise reduction functionality at a fraction of the cost of room modifications.
Solution Approach 2:
The microphone attachment uses inexpensive, replaceable components such as foam windscreen covers and fabric windscreens that can be easily replaced if worn or contaminated. This approach provides effective noise reduction without the high cost of permanent room processing installations.
3Object-affected harmful factors
If room processing is implemented to reduce background noise, then noise reduction effectiveness is improved, but appearance changes
Solution Approach 1:
The noise reduction functionality is extracted from the room structure and transferred to a portable microphone attachment. This allows the room to maintain its original appearance and multifunctionality while the attachment provides noise reduction specifically at the microphone level, preserving the room's aesthetic and versatility.
Solution Approach 2:
Instead of processing the entire room, the noise reduction is applied locally at the microphone position. The attachment provides targeted acoustic treatment only where needed, leaving the rest of the room unchanged and maintaining its original appearance and versatility for different uses.
4Measurement precision
If microphone positioning is optimized to reduce noise, then recording quality is improved, but stability decreases due to performer movement
Solution Approach 1:
The microphone attachment is designed to be flexible and adaptable to performer movement. The windscreen and housing can move with the microphone without compromising the acoustic seal or noise reduction effectiveness, maintaining both recording quality and stability during dynamic performance conditions.
Solution Approach 2:
The windscreen uses flexible fabric or foam materials that can bend and move with performer motion while maintaining the acoustic barrier function. This flexibility allows the microphone to be positioned optimally for recording quality while the attachment maintains stability and noise reduction during performer movement.
