Microphone System Master Slave Mode Power Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Connecting multiple microphones to a single information device is complicated, requiring an additional device for sound synthesis, which complicates the setup process.
Innovation Solution
A microphone system with a first microphone connected to an external device via a USB interface and a second microphone connected through a cable, where the system determines operation modes based on power supply availability, allowing the first microphone to operate in a master mode and the second in a slave mode, enabling direct connection and signal synthesis without additional hardware.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a mixer or additional device is used to synthesize sounds from multiple microphones, then sound synthesis capability is achieved, but device complexity and connection complexity increase
Solution Approach 1:
The patent merges the sound synthesis function into the microphones themselves through master-slave mode operation. The first microphone (master) synthesizes sounds from itself and the second microphone (slave) by processing audio signals internally, eliminating the need for external mixers or additional synthesis devices. This combining of functions reduces overall system complexity while maintaining sound synthesis capability.
2Adaptability or versatility
If a mixer or additional device is used to synthesize sounds from multiple microphones, then sound synthesis capability is achieved, but ease of operation deteriorates
Solution Approach 1:
By integrating the sound synthesis function directly into the microphone system through master-slave mode, the patent eliminates the need for separate mixing devices and complex connection setups. Users simply connect microphones in sequence via USB cables, and the system automatically handles sound synthesis, significantly improving ease of operation.
3Adaptability or versatility
If electric power is supplied through the second connection port to the second microphone, then the second microphone can operate independently, but power management complexity increases
Solution Approach 1:
The patent implements dynamic power management where the determination part automatically switches between master mode (supplying power) and slave mode (receiving power) based on real-time detection of power supply conditions. This dynamic adaptation allows the system to provide independent operation capability while keeping power management transparent and automatic, avoiding additional complexity for users.

AI summary
A microphone includes: a first connection port for connecting to an external device; a second connection port for connecting to a second microphone via a cable; and a determination part that determines to be in a master mode, in which electric power is supplied through the second connection port to the second microphone connected via the cable, when the cable is connected to the second connection port in a state where electric power is supplied from the external device through the first connection port, and determines to be in a slave mode, in which electric power is supplied through the second connection port from the second microphone connected via the cable, when the cable is connected to the second connection port in a state where no electric power is supplied through the first connection port.
