Solution Overview

Problem

Conventional audio systems, such as headphones, fail to adapt their audio output effectively to changing environmental conditions, limiting user experience across different environments.

Innovation Solution

Incorporating a sensor system and control system into audio devices, such as headphones, to detect environmental changes and modify audio output in real-time, including adjusting volume, intensity, and content based on user preferences, location, and ambient noise, using a computer-implemented method that integrates with smart devices and audio libraries.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If audio output is increased to overcome ambient noise, then audibility is improved, but interference with ambient sounds increases

Engineering Contradiction:

ImproveaudibilityVSAvoidinterference with ambient sounds

Core Design Contradiction:

Measurement precisionVSObject-affected harmful factors

Solution Approach 1:

The audio system dynamically adjusts output levels based on real-time environmental conditions detected by sensors. The control system continuously monitors ambient noise levels and modifies audio output accordingly, transitioning from static to adaptive operation to resolve the contradiction between audibility and interference with ambient sounds

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The system uses sensor feedback to detect environmental conditions and adjusts audio output based on this information. The control system receives data from sensors about ambient conditions and modifies the audio signal in real-time, creating a closed-loop system that balances audibility with minimal interference to ambient sounds

Inventive Principle:

Principle #23Feedback

2Object-affected harmful factors

If audio output is decreased to allow ambient sounds to be heard, then interference with ambient sounds is reduced, but audibility deteriorates

3Adaptability or versatility

If audio system is made adaptive to different environments, then user experience is improved, but device complexity increases

Engineering Contradiction:

Improveadaptability to environmentsVSAvoidsystem complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The headphone system integrates multiple functions including audio playback, environmental sensing, and automatic adaptation into a single universal device. The control system performs multiple tasks (receiving sensor data, analyzing environmental conditions, modifying audio output) using one integrated system rather than separate dedicated components for each function

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The system automatically detects environmental conditions and adjusts audio output without user intervention. The control system receives sensor data, determines appropriate audio modifications, and implements changes autonomously, eliminating the need for manual user configuration and simplifying the user interface

Inventive Principle:

Principle #25Self-service

AI summary

Various implementations include headphone systems configured to adapt to changes in user environment. In some particular cases, a headphone system includes at least one headphone including an acoustic transducer having a sound-radiating surface for providing an audio output; a sensor system configured to detect an environmental condition proximate the at least one headphone; and a control system coupled with the at least one headphone and the sensor system, the control system configured to: receive data about the environmental condition from the sensor system; and modify the audio output at the at least one headphone in response to a change in the environmental condition, wherein the audio output includes a continuous audio output provided across a transition between environmental conditions and is configured to vary with the change in the environmental condition.
