Solution Overview

Problem

Current microphone array technologies do not provide a clear visual representation of the acoustic signals they pick up, making it difficult for users to distinguish between crystal voice, noise, and echo in real-time.

Innovation Solution

A method that visualizes the original acoustic signal from array microphones into a figure comprising graphic components representing crystal voice, noise, and echo, with varying lengths and colors to distinguish between different sound components, allowing users to understand what sounds are being picked up in real-time.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If array microphones are used to receive sound from a particular direction while suppressing noise and echo, then the quality of crystal voice reception is improved, but the user cannot visually distinguish between different sound components (crystal voice, noise, echo) in real-time

Engineering Contradiction:
Improvesound component differentiationVSAvoidvisual feedback on acoustic signals
Core Design Contradiction:
Measurement precisionVSLoss of information

Solution Approach 1:

The patent applies color changes to different graphic components to represent different sound components. Crystal voice is represented by a first color, noise by a second color, and echo by a third color. This visual differentiation using color allows users to immediately distinguish between various acoustic signals without losing information about what the microphones are picking up.

Inventive Principle:
Principle #32Color changes

Solution Approach 2:

The patent segments the acoustic signal representation into distinct graphic components, each corresponding to a specific sound type (crystal voice, noise, echo). By dividing the visualization into separate graphical elements with different colors and positions, the system enables clear differentiation of sound components while maintaining complete information about the acoustic environment.

Inventive Principle:
Principle #1Segmentation

2Reliability

If hardware or software processing is applied to cancel echo and suppress noise, then communication quality is improved, but users lack real-time understanding of what sounds are being picked up by the microphones

Engineering Contradiction:
Improvecommunication qualityVSAvoiduser understanding of microphone operation
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The patent introduces graphic components as an intermediary between the microphone array and the user. These graphical representations serve as a mediator that translates complex acoustic processing operations into intuitive visual feedback, allowing users to understand what sounds are being picked up without interfering with the echo cancellation and noise suppression processes.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent implements visual feedback by displaying graphic components that represent the acoustic signals picked up by the microphones in real-time. This feedback mechanism allows users to monitor and understand the microphone operation and sound component differentiation without compromising the reliability of communication quality through hardware or software processing.

Inventive Principle:
Principle #23Feedback

3Measurement precision

If multiple graphic components are used to represent different sound components, then sound component differentiation is improved, but the complexity of the visualization system increases

Engineering Contradiction:
Improvesound component identificationVSAvoidvisualization system complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The patent segments the visualization into distinct graphic components, each representing a specific sound component. By dividing the visualization into separate, well-defined graphical elements with consistent visual characteristics (color, position, size), the system achieves precise sound component identification while managing complexity through systematic segmentation rather than a monolithic complex display.

Inventive Principle:
Principle #1Segmentation

AI summary

A method for showing an array microphone effect includes the steps of obtaining an original acoustic signal from array microphones, and visualizing the original acoustic signal to obtain a figure. The original acoustic signal includes a crystal voice, out-beam noises, background noise, and/or an echo. The figure includes a plurality of graphic components representing the crystal voice, out-beam noise, background noise, and/or echo, respectively.
