Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users find it complicated and difficult to manually control the placement position of sound sources in audio systems, especially in environments with multiple speakers, as existing technologies lack automated control mechanisms that adapt to the timing of beats in sound signals.
Innovation Solution
A sound signal processor that automatically controls sound signal processing by detecting beats and adjusting sound source positions and signal processing in real-time, using a CPU with beat detection, sound source position information processing, and position control to distribute sound signals to speakers for dynamic sound image localization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual control methods are used to adjust sound source positions, then the system structure remains simple, but the ease of operation deteriorates due to complexity and difficulty in manual control
Solution Approach 1:
The system automatically detects beats in the audio signal and adjusts sound source positions without requiring manual user input. The beat detection unit identifies beat timings from the audio signal, and the sound source position information changing unit automatically modifies position data based on these detected beats, enabling the system to serve itself rather than requiring continuous manual control.
Solution Approach 2:
The patent replaces manual mechanical control operations with an automated electronic system. The beat detection unit and position control system use electronic signal processing to automatically adjust sound source positions based on detected beat timings, substituting the need for manual user interaction with an automated electronic control mechanism.
2Extent of automation
If automated beat detection and control systems are implemented, then the ease of operation improves, but the device complexity increases due to additional processing units
Solution Approach 1:
The sound signal processor performs multiple functions within a single integrated system: it detects beats in the audio signal, determines sound source positions, and adjusts these positions based on beat timings. This multi-functional approach consolidates what could be separate complex systems into one unified device, achieving high automation while managing overall system complexity.
Solution Approach 2:
The patent combines the beat detection unit, sound source position information processing, and position control functions into a single integrated sound signal processor. By merging these functions that could operate as separate systems, the patent achieves automated control while avoiding the complexity of multiple independent devices working together.
3Adaptability or versatility
If sound source positions are dynamically adjusted based on beat timing, then the adaptability improves for musical expressions, but the processing time and complexity increase
Solution Approach 1:
The system continuously monitors the audio signal for beat timings in real-time and maintains ready-to-adjust sound source position data. When beats are detected, the position adjustments are immediately applied without requiring additional processing or preparation time, as the system is continuously prepared to respond to beat events.
Solution Approach 2:
The beat detection and position adjustment process operates continuously throughout audio playback. The sound signal processor continuously analyzes the audio signal for beats and continuously updates sound source positions based on detected beat timings, ensuring uninterrupted adaptive control without pauses or delays in the useful action.
