Smart Headphone Automatic Audio Pause via Sound Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional headphones disrupt audio playback when a user needs to engage in conversation, requiring manual removal and affecting user experience.
Innovation Solution
A smart headphone equipped with sensors to detect external information, a memory to store feature information, and a controller to manage audio playback based on comparisons, automatically switching playback states without user intervention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If audio information is continuously played back in the headphone, then the user can enjoy uninterrupted audio content, but the user cannot hear external conversations clearly
Solution Approach 1:
The patent applies dynamics by making the audio playback state changeable based on external conditions. The controller dynamically adjusts the playback state (playing, paused, or stopped) according to the sensor detection results, allowing the system to adapt between continuous playback and conversation modes automatically.
Solution Approach 2:
The patent implements feedback through the sensor that continuously monitors external information and feeds it back to the controller. The controller processes this feedback and adjusts the audio playback accordingly, creating a closed-loop control system that responds to environmental changes.
2Ease of operation
If the user removes the headphone to converse with others, then the user can hear external conversations clearly, but the convenience of wearing the headphone is reduced
Solution Approach 1:
The patent applies self-service by enabling the headphone to automatically detect and respond to conversation scenarios without user intervention. The sensor and controller work together to autonomously determine when to pause or stop playback based on external sound detection, eliminating the need for manual user actions.
Solution Approach 2:
The patent replaces the mechanical action of removing the headphone with an electronic sensing and control system. Instead of physically taking off the device, the sensor detects external sounds and the controller electronically adjusts the playback state, substituting a mechanical user action with an automated electronic system.
3Ease of operation
If the headphone automatically senses and responds to external information, then the convenience for the user is improved, but the energy consumption increases
Solution Approach 1:
The patent applies periodic action by having the sensor detect external information at specific intervals or triggered by certain conditions, rather than continuously monitoring at full power. The controller processes sensor data periodically or event-driven, reducing overall energy consumption while maintaining effective automatic playback control.

AI summary
The present disclosure provides a smart headphone. The smart headphone includes a sensor configured to sense external information, a memory configured to store feature information, and a controller operatively connected to the sensor and the memory, respectively, and the controller is configured to compare the external information sensed by the sensor with the feature information stored in the memory, and to control a playback state of audio information in the smart headphone according to the result of the comparison.
