Audio Playback Device Dynamic Channel Matching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Modern audio playback systems face distortion issues due to mismatched sound channel numbers between user-adjusted speaker configurations and audio data formats provided by music streaming websites, leading to suboptimal playback quality.
Innovation Solution
An audio playback device and method that dynamically retrieves and plays audio data with a specific sound channel number equal to or greater than the total sound channel number of the device, using a network communication unit and processing unit to ensure compatibility and minimize distortion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the audio playback system uses a fixed speaker configuration, then the device structure is simple, but it cannot adapt to different user requirements and audio formats
Solution Approach 1:
The audio playback device dynamically determines the total sound channel number based on the actual connected speaker configuration rather than using a fixed configuration. The processing unit automatically adjusts the audio data retrieval parameters according to the detected speaker setup, enabling the system to adapt between 2.0, 2.1, 5.1, 7.1 and other channel configurations without requiring manual intervention or complex hardware redesign
Solution Approach 2:
The audio playback system is divided into independent functional modules: a speaker detection module that identifies the connected speaker configuration, a processing unit that determines the total sound channel number, and a network communication unit that retrieves appropriate audio data. This modular segmentation allows each component to perform its function independently while contributing to the overall adaptability of the system
2Reliability
If the audio data channel number does not match the speaker configuration, then the system can play various audio formats, but sound distortion occurs
Solution Approach 1:
The processing unit receives feedback about the total sound channel number from the speaker configuration detection, then uses this feedback to control the network communication unit to retrieve audio data with matching channel numbers. This closed-loop feedback mechanism ensures that the retrieved audio data always corresponds to the actual speaker setup, preventing sound distortion while maintaining compatibility with various audio formats
Solution Approach 2:
Before playing audio data, the system preliminarily determines the total sound channel number based on the connected speaker configuration and uses this information to select and retrieve the appropriate audio data format. This preliminary action ensures that the correct audio data is retrieved before playback begins, avoiding distortion issues that would occur with mismatched channel configurations
3Reliability
If the system retrieves audio data with higher channel numbers, then playback quality is improved, but network bandwidth and decoding resources are wasted
Solution Approach 1:
The system changes the parameter of audio data channel number to exactly match the total sound channel number of the connected speaker configuration. Rather than always retrieving the highest quality audio data or using a fixed channel number, the processing unit dynamically adjusts the channel number parameter based on the detected speaker setup, ensuring optimal playback quality while minimizing network bandwidth consumption and decoding resource usage

AI summary
An audio playback method used in an audio playback device is provided. The audio playback method includes steps outlined below. An audio playback command is received by a processing unit through a network communication unit. A total sound channel number of the audio playback device is determined by the processing unit. A piece of audio data having a specific sound channel number is retrieved by the processing unit through the network communication unit from internet, wherein the specific sound channel number is equal to or larger than the total sound channel number. Audio playback modules are controlled to play an audio by the processing unit according to the audio data.
