Headphone Sound Effect Compensation With Unit-Specific Parameters
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing headphone sound effect compensation methods using universal parameters result in poor sound effect compensation effects due to differences between headphones of different models, serial numbers, or left and right headphones, affecting user experience.
Innovation Solution
Each headphone stores a corresponding sound effect compensation parameter, which it shares with the electronic device for personalized sound effect compensation, and can perform compensation independently if the device lacks this capability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a universal headphone sound effect compensation parameter is used, then the electronic device can maintain simplicity in parameter management, but the sound effect compensation effect deteriorates due to differences between individual headphones
Solution Approach 1:
The patent divides the universal compensation parameter into individual headphone-specific parameters. Each headphone is measured separately to obtain its unique compensation parameter, transforming a single universal parameter into multiple segmented parameters tailored to each headphone unit. This segmentation resolves the contradiction by accepting increased parameter management complexity in exchange for significantly improved compensation precision.
Solution Approach 2:
The patent implements local quality by creating customized compensation parameters for each specific headphone based on its individual characteristics. Instead of applying a uniform compensation standard to all headphones, the system measures and determines unique compensation parameters for each headphone model, serial number, or even left-right headphone pairs, thereby achieving high precision compensation adapted to local (individual) qualities.
2Manufacturing precision
If individual headphone sound effect compensation parameters are stored and used, then the sound effect compensation effect improves, but the device complexity increases due to storing and managing multiple parameters
Solution Approach 1:
The patent applies self-service by enabling the electronic device to automatically measure, determine, and store compensation parameters for each headphone through an automated measurement process. The system performs impulse response measurement, calculates compensation parameters, and stores them in the database without requiring manual intervention. This automation reduces the perceived complexity by making the system self-configuring.
Solution Approach 2:
The patent implements preliminary action by pre-measuring and storing compensation parameters for each headphone before actual audio playback. The measurement and parameter determination process is performed in advance during device pairing or initialization, so that when audio playback occurs, the appropriate compensation parameter is already available in the database, eliminating the need for real-time calculation and reducing operational complexity.
3Manufacturing precision
If different compensation parameters are used for different headphones, then the sound effect compensation precision improves, but the resource consumption increases due to storing multiple parameters
Solution Approach 1:
The patent applies universality by creating a multi-functional compensation parameter database that serves multiple purposes: it stores parameters for different headphone models, different serial numbers, and different left-right headphone pairs. The same database infrastructure and parameter structure are used universally across all these variations, allowing the system to handle diverse compensation needs with a unified storage solution rather than requiring separate storage systems for each scenario.

AI summary
If the electronic device has a headphone sound effect compensation function, the headphone sends first information to the electronic device, where the first information indicates that the headphone has a capability of reporting the headphone sound effect compensation parameter; the electronic device sends second information to the headphone based on the first information, where the second information is used to request the headphone sound effect compensation parameter; the headphone receives the second information, and sends, based on the first information, the headphone sound effect compensation parameter to the electronic device; and the electronic device receives the headphone sound effect compensation parameter; and performs, based on the headphone sound effect compensation parameter in response to an operation of triggering playing audio by a user, headphone sound effect compensation on the audio played by the user.
