Audio Device Repeat Reproduction Controller
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing audio device technologies face challenges in seamless repeat reproduction of audio files without interruptions or time lags, especially when the repeat reproduction range exceeds memory capacity or when user intent is uncertain, leading to unnecessary data storage and potential noise or silence during transitions.
Innovation Solution
An information processor and audio device with a controller that manages multiple player applications, allowing one player application to set another to a wait state upon completion of its reproduction, enabling seamless switching and repeat reproduction without pre-storing sound data, thus eliminating interruptions and time lags.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If sound data of a predetermined period is stored in memory in advance to prevent interruption during repeat reproduction, then reproduction continuity is improved, but memory usage increases and unnecessary data storage occurs when user intent is uncertain
Solution Approach 1:
The system performs preliminary actions by activating the second player application in advance and setting it to a wait state with reproduction data ready, but does not store predetermined periods of sound data in memory. The second player application is prepared to immediately take over when the first player application completes, eliminating the need for buffer storage while ensuring continuity.
Solution Approach 2:
The system uses a copy approach by having the second player application ready with reproduction data that is essentially a copy or duplicate of what the first player application will play next. This allows seamless switching without requiring large memory buffers, as the second player has the necessary data ready in a wait state.
2Adaptability or versatility
If the repeat reproduction range exceeds memory storage capacity, then more audio content can be repeated, but data connection without noise or silence becomes difficult
Solution Approach 1:
The second player application is activated in advance and positioned at the start point of the repeat range with reproduction data ready. When the first player completes, the second player immediately starts reproduction without needing to connect disparate data segments, eliminating noise or silence issues that would occur with manual data concatenation for ranges exceeding memory capacity.
Solution Approach 2:
The system segments the repeat reproduction function into two independent player applications instead of using a single player with large memory buffers. This segmentation allows each player to handle smaller, manageable data segments while achieving the effect of repeating larger ranges, as the second player is pre-positioned to continue from where the first player ends.
3Reliability
If multiple player applications are activated for seamless switching, then reproduction continuity is improved, but system complexity increases
Solution Approach 1:
The system merges the functionality of multiple player applications under a single controller that manages their activation and switching. The controller coordinates the first and second player applications, setting the second to a wait state and automatically activating it when the first completes, thereby reducing the perceived complexity while maintaining the benefits of multiple players for seamless reproduction.

AI summary
A desired range of an audio file is repeatedly reproduced without a need to store sound data of a predetermined period in a memory in advance and without causing an interruption or a time lag. A CPU of an audio device activates at least two media players A and B for reproducing an audio file. During reproduction of the audio file by the media player A, the media player B is set to a wait state, and, in response to completion of the reproduction of the audio file by the media player A, the wait state of the media player B is automatically released and reproduction of the audio file is started, to achieve repeat reproduction.
