Audio Device Controller Using Microphone Array for External Speaker Localization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional audio devices require an external microphone for adjusting sound settings, which is inconvenient and necessitates additional equipment and frequent adjustments when the speaker location or direction changes.
Innovation Solution
An audio device equipped with multiple microphones and a controller that determines the external audio device's location and adjusts audio output settings based on received signals, eliminating the need for a separate external microphone.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If an external microphone is used to adjust audio output settings, then the sound quality can be optimized for the installation environment, but the device complexity increases and the ease of operation deteriorates due to requiring additional equipment and frequent adjustments
Solution Approach 1:
The patent merges the audio output function and audio input function into a single audio device. The speaker unit outputs audio signals while the microphone unit receives audio signals, allowing the device to perform both output and environmental assessment functions without requiring external equipment.
Solution Approach 2:
The audio device is designed with multi-functionality, serving as both an audio output device (speaker) and an audio input device (microphone). This universal design eliminates the need for separate external microphones and enables the device to adapt to different installation environments using its built-in microphone.
2Reliability
If an external microphone is used to adjust audio output settings, then the sound quality can be optimized for the installation environment, but the ease of operation worsens due to requiring frequent adjustments when speaker location or direction changes
Solution Approach 1:
The patent implements a feedback mechanism where the microphone unit receives audio signals from the environment, the controller analyzes these signals to determine installation environment information, and then adjusts the audio output settings accordingly. This automated feedback loop eliminates the need for manual repeated adjustments.
Solution Approach 2:
The audio device performs self-adjustment of its output settings based on environmental feedback received through its built-in microphone. The controller automatically determines the installation environment and optimizes audio parameters without requiring user intervention, making the device self-sufficient and easy to operate.
3Reliability
If an external microphone is used to adjust audio output settings, then the sound quality can be optimized for the installation environment, but the ease of operation deteriorates due to requiring additional equipment
Solution Approach 1:
The patent merges the audio output function and audio input function into a single audio device. The speaker unit outputs audio signals while the microphone unit receives audio signals, allowing the device to perform both output and environmental assessment functions without requiring external equipment.

Data Source
AI summary
The present disclosure relates to an audio device and an operation method thereof. The audio device may include a speaker; a plurality of microphones spaced a predetermined distance apart from each other; and controller. The controller controls the plurality of microphones to receive audio output from an external audio device, determines a location of the external audio device on the basis of signals received from the plurality of microphones and adjusts a setting for an audio output from at least one of the external audio device and the speaker, based on the location of the external audio device.
