Switching Device for True Diversity Receiver Signal Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional true diversity receivers are limited to single-receiving dual true diversity or dual-receiving single true diversity modes, resulting in restricted effective ranges and interference issues when used outdoors or indoors, respectively.
Innovation Solution
A switching device with a control switch between two microcontrollers of two antennas that switches RF wireless microphone signals to execute either a single-receiving dual true diversity or dual-receiving single true diversity program, allowing simultaneous use of two wireless microphones and enhancing effective receiving distance by eliminating dead spaces through differential antenna positioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If dual-receiving single true diversity mode is used, then the receiving range is increased, but wireless microphones interfere with each other when used indoors
Solution Approach 1:
The patent implements dynamic mode switching between dual-receiving single true diversity and single-receiving dual true diversity modes based on operational requirements. The control switch allows the system to adapt its receiving configuration dynamically, selecting the appropriate mode to either maximize receiving range or eliminate interference depending on the specific application scenario.
2Object-generated harmful factors
If single-receiving dual true diversity mode is used, then interference is eliminated, but the effective receiving distance is limited
Solution Approach 1:
The patent designs the receiving device to perform multiple functions by supporting both single-receiving dual true diversity mode and dual-receiving single true diversity mode. This multi-functionality allows the same hardware configuration to serve different operational needs, whether maximizing receiving distance or eliminating interference, without requiring separate dedicated systems for each mode.
3Adaptability or versatility
If a control switch is added to enable mode switching, then the device complexity increases, but the adaptability to different environments is improved
Solution Approach 1:
The control switch enables dynamic adaptation between different operating modes, allowing the system to adjust its behavior based on environmental requirements. This dynamic capability provides high adaptability to different scenarios (indoor vs. outdoor, single vs. multiple microphones) while maintaining a relatively simple implementation through a straightforward switching mechanism.

AI summary
A switching device is adapted for a true diversity receiver and contains: a control switch defined between two microcontrollers of two antennas and configured to switch RF wireless microphone signals so that the two microcontrollers execute a single-receiving dual true diversity program or a dual-receiving single true diversity program. The RF wireless microphone signals are received by the two antennas and are decoded to sound signals by two digital decoders respectively, and the sound signals are sent to two audio signal processors by a multiplexer which corresponds to the two microcontrollers to switch the sound signals of a single-receiving dual true diversity or a dual-receiving single true diversity. Thereafter, the sound signals are output by a sound signal mixer.
