Multi-mode Microphone with Rotary Switch for Mono Stereo Adaptation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Videographers need to purchase and switch between mono and stereo microphones depending on acoustical requirements, which is inefficient and costly.
Innovation Solution
A multifunction microphone that can be easily switched between mono and stereo modes without removal or replacement, using a mechanism that rotates the microphone assembly to activate either the mono or stereo input/output mode electronically.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a videographer purchases both mono and stereo microphones to meet different acoustical requirements, then the ability to capture sound in different modes is improved, but the cost and device complexity increase
Solution Approach 1:
The patent combines both mono and stereo microphone capsules within a single housing structure. The housing contains a first microphone capsule for mono reception and a second microphone capsule for stereo reception, integrating multiple functions into one device. This merging eliminates the need for separate microphones while maintaining both acoustical capabilities.
Solution Approach 2:
The single microphone device is designed to perform multiple functions by receiving sound in both mono and stereo modes. The switchable configuration allows the same physical device to adapt to different acoustical requirements, making it a universal solution that replaces multiple specialized microphones.
2Reliability
If a videographer uses separate mono and stereo microphones, then each microphone can be optimized for its specific mode, but the ease of operation deteriorates due to the need to switch between microphones
Solution Approach 1:
The microphone incorporates a switchable mechanism that allows dynamic reconfiguration between mono and stereo modes. The housing can be rotated or switched to engage different microphone capsules with the camera interface, enabling the user to change modes without replacing the entire microphone assembly. This dynamic switching maintains optimized performance for each mode while improving operational convenience.
3Adaptability or versatility
If multiple microphones are used to cover different acoustic needs, then the adaptability is improved, but the loss of time increases due to removal and reconnection
Solution Approach 1:
By merging both mono and stereo microphone capsules into a single housing that connects to the camera as one unit, the patent eliminates the time required to physically remove and reconnect different microphones. The switchable mechanism allows mode changes within the connected state, reducing switching time to minimal mechanical adjustment without interruption of the recording setup.

AI summary
A multi-mode microphone assembly includes a mono microphone, a stereo microphone, and a rotary switch contained within a housing. The mono microphone has a mono input/output mode and the stereo microphone has a stereo input/output mode. Only one input/output mode is active depending on the position of the rotary switch within the housing. When the rotary switch is in a first position only the mono input/output mode is activated and when the rotary switch is in a second position the mono input/output mode is deactivated and the stereo input/output mode is activated. The first position of the rotary switch corresponds to a first position of the housing. The second position of the rotary switch corresponds to a second position of the housing. The first and second positions of the housing are offset 180 degrees from one another.
