Solution Overview

Problem

Existing earphones fail to cater to individual auditory sensitivities, leading to increased volume adjustment which compromises sound quality and hearing comfort, particularly affecting perception of specific frequency bands.

Innovation Solution

An auditory enhancement method that extracts frequency points from audio data, creates a personalized auditory test environment, collects user feedback, and generates auditory gain values based on identity and test results to enhance sensitivity without altering volume.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the volume of earphones is turned up to hear sounds in certain frequency bands more easily, then the ease of operation is improved, but the sound quality deteriorates and hearing comfort is reduced

Engineering Contradiction:
Improveease of hearing certain frequency bandsVSAvoidsound quality
Core Design Contradiction:
Ease of operationVSManufacturing precision

Solution Approach 1:

The patent applies local quality by creating personalized equalization curves that adjust different frequency bands individually based on user-specific auditory sensitivity characteristics. Instead of uniformly increasing volume, the system identifies specific frequency ranges where each user has reduced sensitivity and applies targeted amplification only to those bands, thereby improving ease of hearing without compromising overall sound quality or causing excessive volume increase.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The patent utilizes parameter changes by measuring user auditory sensitivity across multiple frequency points and using these measurements to dynamically adjust equalization parameters. The system transforms raw sensitivity data into personalized equalization curves that modify audio output parameters in real-time, allowing the earphones to adapt their frequency response characteristics to each user's unique auditory profile.

Inventive Principle:
Principle #35Parameter changes

2Ease of operation

If the volume of earphones is turned up to hear sounds in certain frequency bands more easily, then the ease of operation is improved, but hearing comfort deteriorates

Engineering Contradiction:
Improveease of hearing certain frequency bandsVSAvoidhearing comfort
Core Design Contradiction:
Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The patent applies local quality by creating personalized equalization curves that adjust different frequency bands individually based on user-specific auditory sensitivity characteristics. Instead of uniformly increasing volume, the system identifies specific frequency ranges where each user has reduced sensitivity and applies targeted amplification only to those bands, thereby improving ease of hearing without compromising overall sound quality or causing excessive volume increase.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The patent converts the harmful effect of volume increase into a beneficial solution by using measured auditory sensitivity data to generate compensatory equalization curves. The system takes the 'harm' of reduced sensitivity in certain frequency bands and transforms it into a benefit by automatically applying precise frequency-specific amplification, eliminating the need for users to increase overall volume and thereby protecting hearing comfort.

Inventive Principle:
Principle #22Blessing in disguise (Convert harm into benefit)

3Adaptability or versatility

If personalized auditory enhancement is implemented, then the adaptability is improved, but the device complexity increases

Engineering Contradiction:
Improvepersonalization to user auditory sensitivityVSAvoidcomplexity of auditory test and processing system
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent applies segmentation by dividing the auditory sensitivity measurement process into discrete frequency points (e.g., 250Hz, 500Hz, 1kHz, 2kHz, 4kHz, 8kHz) that are tested independently. This segmentation allows the complex measurement task to be broken down into manageable steps, with each frequency point contributing to the overall sensitivity profile. The segmented data is then used to construct personalized equalization curves through systematic processing.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent utilizes feedback by measuring user auditory sensitivity and using this measured data to automatically adjust equalization parameters. The system creates a closed-loop process where auditory test results feed into the equalization curve generation, which in turn modifies the audio output. This feedback mechanism enables the system to adapt to each user's unique characteristics without requiring manual configuration, thereby managing complexity through automation.

Inventive Principle:
Principle #23Feedback
