Solution Overview
Problem
Conventional wireless microphone systems face challenges in achieving real-time audio transmission with low latency, maintaining signal integrity over long-term operation, and providing a compact, lightweight design while ensuring secure attachment of windshields and minimizing interference-induced signal drops.
Innovation Solution
A compact wireless microphone system featuring a receiver with connector ports, transmitters with built-in antennas and controllers for real-time audio processing and transmission, and a windshield secured via a bayonet fastener to reduce wind noise. The system includes processing paths for raw and compressed audio recording and transmission, with automatic dropout tagging and peak audio file recording for efficient editing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a conventional windshield is attached to the transmitter, then wind noise dampening is provided, but the windshield may fall off the transmitter
Solution Approach 1:
The windshield attachment system is segmented into multiple components: a mounting structure with mounting arms that extend into recesses, a bayonet fastener with distinct engagement features, and corresponding receptacles. This segmentation creates multiple discrete attachment points and mechanisms, ensuring the windshield remains securely attached while allowing for reliable installation and removal.
2Loss of time
If audio data is transmitted in real-time with low latency, then synchronization with video is improved, but transmission reliability over long-term operation deteriorates
Solution Approach 1:
The audio transmission system dynamically adjusts between real-time transmission modes (for low latency and video synchronization) and reliable transmission modes (for long-term operational stability). The system can switch between transmitting raw audio data for immediate processing and compressed audio data for more robust transmission, allowing optimization based on current operational requirements.
3Weight of moving object
If the system is designed to be compact and lightweight, then portability is improved, but transmission range deteriorates
Solution Approach 1:
The transmitter integrates multiple functions into a single compact unit: the audio recording capabilities, compression encoder, wireless transmission module with antenna, and battery power source are all merged into one housing. This consolidation achieves a lightweight, portable design while maintaining adequate transmission range through efficient use of space and integrated component design.
4Productivity
If audio data is compressed before transmission, then transmission efficiency is improved, but recording quality deteriorates
Solution Approach 1:
The system applies different quality levels to different audio processing paths: raw, uncompressed audio data is maintained at high quality for local recording and immediate use, while compressed audio data is generated for transmission efficiency. This allows the system to preserve audio quality where needed while optimizing transmission performance, with the ability to recover high-quality audio from the uncompressed recording path.

AI summary
The invention relates generally to a wireless microphone system and methods. The system may include one or more antennas, such as a monopole and dipole antennas, arranged within a housing. The housing may include a circuit boarding having a ground plane. The circuit board may be connected to a microphone configured to protrude from an opening of the housing. Further, a windshield including a bayonet-type connector may removably mount with a mount on the housing. Advantageously, the system may be configured to provide noise dampening and facilitate linking with other devices more efficiently and effectively.
