Wireless Microphone Transmitter Remote Control via External Interface
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless microphone systems for news broadcasts and similar applications face poor operability when used alone, as they require the reporter to physically interact with a camcorder or audio mixer for operations, leading to inefficiencies and increased staff requirements, while attempts to add remote operation capabilities compromise miniaturization and increase operational complexity.
Innovation Solution
A wireless audio transfer system that includes an audio transmitting apparatus with a connection terminal for a human interface device, allowing data corresponding to device operations to be transmitted as radio waves, and an audio receiving apparatus with a data processing unit to output control signals, enabling remote operation of image pickup, recording, or audio mixer devices without adding buttons to the transmitter.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If dedicated operation buttons are added to the transmitter for remote operation, then operability is improved, but the transmitter size increases and miniaturization progress is obstructed
Solution Approach 1:
The patent replaces physical buttons on the transmitter with a connection terminal that accepts external human interface devices (mouse, keyboard, touch panel). This substitution allows remote operation functionality to be added without increasing transmitter size, as the control interface is moved to an external device connected via terminal.
Solution Approach 2:
The connection terminal is designed to accept various types of human interface devices (mouse, keyboard, touch panel), making the transmitter capable of multiple operation modes. This universal interface allows the same terminal to support different input devices, providing versatility without adding dedicated buttons for each function.
2Ease of operation
If dedicated operation buttons are added to the transmitter, then remote operation capability is improved, but the number of operation buttons increases making the operation system more complex
Solution Approach 1:
The patent extracts the operation buttons from the transmitter body and places them on an external human interface device. This separation removes the complexity of multiple buttons from the transmitter, keeping the transmitter design simple while still providing comprehensive remote operation capability through the external device.
Solution Approach 2:
The connection terminal acts as an intermediary between the external human interface device and the transmitter. It receives signals from various types of input devices and translates them into appropriate control commands, simplifying the interface design by providing a universal connection point rather than multiple dedicated controls.
3Productivity
If the reporter walks up to the camcorder or audio mixer for operations, then direct control is achieved, but operability deteriorates and filming efficiency decreases
Solution Approach 1:
The transmitter is equipped with a connection terminal that allows the reporter to connect and operate the camcorder or audio mixer directly from the transmitter location. This self-service capability enables the reporter to control the equipment without leaving their position, improving both operability and filming efficiency.

Function Achieved in This Case
This solution enhances operability by allowing users to remotely control camcorders or audio mixers using common human interface devices like mice or keyboards, maintaining the miniaturization of wireless microphones while simplifying operations and reducing the need for additional staff.
Implementation Method 1
a modulating/transmitting unit that transmits radio waves that have been modulated using an audio signal from the microphone
Implementation Method 2
a receiving/demodulating unit that receives radio waves transmitted from the transmitter and demodulates the audio signal
