Multi-Audio Playback Unit for Simultaneous Format Mixing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional MP3 handsets are unable to simultaneously play and control various audio formats, limiting user experience and failing to meet increasing consumer demands for playing different sound sources.
Innovation Solution
A mobile device with multiple audio-playing units, each corresponding to different audio formats, a processor for handling hardware interrupts, and an output unit for mixing and outputting analog sound signals, along with a volume control interface to manage audio playback.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional MP3 handset architecture is used with single audio-playing unit, then device complexity is reduced, but audio format versatility is limited
Solution Approach 1:
The audio playback system is segmented into multiple independent audio-playing units (first audio-playing unit for MP3 format, second audio-playing unit for WAV format), each capable of handling specific audio formats. This segmentation allows the device to support multiple audio formats simultaneously while maintaining clear functional boundaries for each unit, resolving the contradiction between versatility and complexity.
Solution Approach 2:
The patent implements multi-functionality by enabling the mobile device to play multiple audio formats (MP3, WAV, and other formats) through separate dedicated playing units. Each unit is designed to handle specific formats, yet collectively they provide universal audio playback capability across different format types, allowing the device to adapt to various audio sources.
2Adaptability or versatility
If multiple audio-playing units are implemented, then audio format versatility is improved, but device complexity increases
Solution Approach 1:
The mixing unit serves as an intermediary component that receives analog audio signals from multiple audio-playing units and combines them into a unified output. This mediator component simplifies the overall system architecture by providing a centralized point for signal convergence, reducing the complexity that would otherwise arise from managing multiple independent playback paths.
Solution Approach 2:
The patent merges multiple analog audio signals from different audio-playing units through a mixing unit that combines them into a single mixed audio output. This combining approach allows simultaneous playback of multiple audio formats while consolidating the output path, thereby managing device complexity through signal convergence rather than requiring separate output channels for each format.
3Ease of operation
If simultaneous playback of multiple audio formats is enabled, then user experience is enhanced, but control complexity increases
Solution Approach 1:
The processor monitors the playback status of multiple audio-playing units and dynamically adjusts their operation based on detected conditions. When an audio file playback is detected in one unit, the processor automatically controls the playback state of other units, providing intelligent feedback-based management that simplifies user interaction while enabling simultaneous multi-format playback capability.
Data Source
AI summary
A mobile device playing and outputting audio data having various formats. The mobile device includes a memory storing audio data having different formats; a plurality of audio-playing units, each having a codec that corresponds a respective format and restoring respective analog sound signals from the corresponding audio data; a processor receiving a hardware interrupt from some or all of the audio-playing units to provide corresponding data of the stored audio data to a corresponding audio playing unit; and an output unit mixing the restored analog sound signals in order to be output.
