Solution Overview

Problem

Existing portable terminals, such as smartphones, often fail to provide optimal sound output when using third-party headphones or earphones, as they are optimized for bundled receivers, leading to suboptimal audio quality due to varying output characteristics among different receiver models.

Innovation Solution

A method and apparatus that store receiver identifications and corresponding sound signal control parameters, allowing users to select their receiver type and adjust sound signal output accordingly, converting digital sound signals into analog signals using specific parameters to match the selected receiver's characteristics.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Manufacturing precision

If the terminal outputs sound signal optimized for bundled receiver, then the sound quality is optimal for bundled receiver, but the sound quality becomes suboptimal for third-party receivers with different output characteristics

Engineering Contradiction:
Improvesound qualityVSAvoidcompatibility with different receivers
Core Design Contradiction:
Manufacturing precisionVSAdaptability or versatility

Solution Approach 1:

The patent implements dynamic sound signal adjustment by allowing the terminal to automatically detect receiver characteristics and adapt the sound signal parameters in real-time. The system transitions from a fixed optimized signal to a dynamically adjustable signal that adapts to different receiver types, resolving the contradiction between optimization for specific receiver and compatibility with various receivers.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent changes the parameters of the sound signal based on receiver characteristics. By detecting receiver output characteristics and adjusting sound signal parameters accordingly, the system maintains optimal sound quality across different receiver models while preserving compatibility with third-party receivers.

Inventive Principle:
Principle #35Parameter changes

2Device complexity

If the terminal provides fixed sound signal output, then the device complexity is low, but the adaptability to different receiver models is poor

Engineering Contradiction:
Improvesound signal processingVSAvoidreceiver compatibility
Core Design Contradiction:
Device complexityVSAdaptability or versatility

Solution Approach 1:

The patent implements self-service by enabling the terminal to automatically detect receiver characteristics and adjust sound signal parameters without requiring manual user configuration. The system autonomously identifies receiver type and optimizes output parameters, reducing user burden while improving adaptability to different receivers.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The patent incorporates feedback mechanisms where the terminal detects receiver output characteristics and uses this information to adjust sound signal parameters. This closed-loop feedback system enables automatic adaptation to different receivers while maintaining relatively simple device architecture.

Inventive Principle:
Principle #23Feedback

AI summary

A method and an apparatus control sound signal output. The method of controlling a sound signal output in a terminal includes: storing receiver identifications and corresponding sound signal control parameters associated with each other by the terminal; providing a receiver selection interface capable of selecting one from a list of the receiver identifications and the receiver identifications included in the list by the terminal; receiving one receiver identification through the receiver selection interface; converting a digital sound signal into an analog sound signal by applying a sound signal control parameter corresponding to the received receiver identification; and outputting the analog sound signal.
