Terminal Audio Control to Prevent Double Sound Quality Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Audio data may be reproduced with unintended sound quality due to double sound quality adjustments performed on both the transmission and reception sides of devices during audio data transmission.
Innovation Solution
A terminal device with a communication unit, a sound quality adjustment unit, and a control unit that determines whether the connected audio reproduction device has a sound quality adjustment function based on a communication protocol, and accordingly enables or disables the sound quality adjustment function to prevent double adjustments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If sound quality adjustment is performed on both transmission side and reception side devices, then sound quality can be optimized at each stage, but double sound quality adjustment occurs causing reproduction with unintended sound quality
Solution Approach 1:
The terminal device performs sound quality adjustment on audio data before transmission to the audio reproduction device. By applying the adjustment in advance on the transmission side, the audio data is pre-optimized for the intended sound quality, eliminating the need for additional sound quality adjustment on the reception side and preventing double adjustment issues.
Solution Approach 2:
The sound quality adjustment function is extracted and concentrated on the terminal device (transmission side) only, rather than being distributed to both transmission and reception devices. This centralization of the adjustment function ensures that only one device modifies the audio data, preventing unintended sound quality changes from multiple adjustments.
2Manufacturing precision
If sound quality adjustment function is always enabled on terminal device, then audio data can be optimized for playback, but unnecessary processing occurs when the audio reproduction device already has sound quality adjustment capability
Solution Approach 1:
The sound quality adjustment function on the terminal device is made dynamic and controllable. The processing unit can selectively enable or disable the sound quality adjustment based on communication results with the audio reproduction device. This dynamic control allows the system to adapt to different scenarios, enabling adjustment only when necessary and avoiding unnecessary processing energy consumption.
Solution Approach 2:
The system changes the operational parameter (sound quality adjustment enable/disable state) of the terminal device based on communication results. By detecting whether the audio reproduction device has sound quality adjustment capability through communication, the terminal device adjusts its own processing state accordingly, optimizing energy usage while maintaining audio quality when needed.

AI summary
Provided is a terminal device including: a communication unit that communicates with an audio reproduction device; a sound quality adjustment unit that performs sound quality adjustment on audio data; and a control unit that determines whether or not the audio reproduction device has a sound quality adjustment function depending on a communication result of communication based on a predetermined protocol, and turns on or off the sound quality adjustment function of the sound quality adjustment unit depending on a determination result.
