Microphone-Based Volume Control for Noise-Canceling Audio Alerts
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users of noise-canceling earphones often fail to receive timely external sound feedback, leading to potential accidents or social misunderstandings due to the isolation from external noise.
Innovation Solution
An electronic device with microphones that intelligently controls volume by extracting external sound content, matching it with a prestored sound template database, and adjusting or turning off the output sound to alert the user through a prompt tone, taking into account the sound source's position and distance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If noise-canceling earphones are used to block external noise, then noise reduction performance is improved, but user awareness of external sounds deteriorates
Solution Approach 1:
The system continuously monitors external sounds through microphones and provides feedback to the user by adjusting music volume or issuing prompts when important sounds are detected, creating a closed-loop information feedback mechanism that compensates for the isolation caused by noise canceling
Solution Approach 2:
The electronic device acts as an intermediary between the external environment and the user, detecting external sounds and translating them into appropriate volume adjustments or prompt tones that alert the user without requiring direct exposure to external noise
2Productivity
If volume of music is continuously played, then user entertainment is maintained, but user safety deteriorates due to inability to hear external sounds
Solution Approach 1:
The music volume is dynamically adjusted based on real-time external sound detection, transitioning between different playback states (continuous play, volume reduction, pause with prompt) according to the detected sound environment and user needs
Solution Approach 2:
The system proactively detects potential safety issues by monitoring external sounds and takes preventive action by adjusting volume or issuing prompts before the user encounters a safety situation
3Loss of information
If prompt tone is generated to alert user, then user awareness of external sounds is improved, but user experience deteriorates due to interruption of music playback
Solution Approach 1:
The system changes the parameter of music playback state (continuous play, volume adjusted, or paused with prompt) based on the importance and characteristics of detected external sounds, providing a graduated response rather than a binary on/off approach

AI summary
The present invention discloses a method and an implementation apparatus for intelligently controlling volume of an electronic device, where the electronic device is installed with microphones. The method includes receiving an external sound picked up by the microphones, extracting content information of the external sound, determining, according to the content information of the external sound, whether a prestored sound template database includes a sound that is matched with the content information of the external sound, and generating a first determining result. If the first determining result is yes, the method includes adjusting volume of a sound that is being output, or generating a prompt tone, turning off a sound that is being output, and outputting the prompt tone. In the present invention, an electronic device is enabled to intelligently control its own volume according to an external sound.
