Acoustic Mode Switching for Electronic Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electronic devices lack the ability to automatically adjust their alert modes based on the surrounding environment, leading to unnecessary disturbances during events like meetings.
Innovation Solution
An electronic device with modules that collect and filter sounds, confirm prominent voices, and switch between silent and ringing modes based on predefined scenarios, using a controlling module to manage these changes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If the electronic device operates in ringing mode, then the user can be notified of incoming calls, but it causes disturbances during meetings or quiet environments
Solution Approach 1:
The patent applies dynamics by making the alert mode changeable based on environmental conditions. The device dynamically switches between ringing mode and silent mode according to the detected acoustic environment, allowing the notification function to adapt to different situations rather than remaining static
Solution Approach 2:
The patent implements feedback by using the acoustic sensor to continuously monitor the surrounding environment and feed this information back to the controller. The controller then adjusts the alert mode based on this feedback, creating a closed-loop system that automatically responds to environmental changes
2Object-affected harmful factors
If the electronic device automatically switches modes based on environment, then disturbances are reduced, but the device complexity increases
Solution Approach 1:
The patent applies self-service by enabling the device to automatically detect environmental conditions and switch modes without user intervention. The acoustic sensor and controller work together to autonomously determine when to activate silent mode or ringing mode, making the system self-regulating
Solution Approach 2:
The patent implements universality by designing a mode switching system that can adapt to various environments (meetings, quiet spaces, normal settings) using the same acoustic detection mechanism. The system handles multiple scenarios through a single unified approach based on acoustic level detection

AI summary
A method for switching modes of an electronic device is presented. The method can collect sound of the predetermined scenario by a collector of the electronic device, and confirm prominent sound from the collected sound. When the duration of the prominent sound is greater than or equal to a first period of time, the method can confirm that the prominent sound is a sample sound, and switch the silent mode to ringing mode of the electronic device when the collector has not collected the prominent sound during a second period of time.
