Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vibration signal generation techniques fail to effectively induce relaxation or awakening effects in listeners when the music played does not inherently have these effects.
Innovation Solution
A vibration signal generation device that determines a mode from multiple modes and extracts specific frequency bands from the audio signal to generate vibration signals, allowing for targeted mental and physical state effects, even with music that has no relaxation or awakening effect.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a piece of music that has no relaxation or awakening effect is played, then the music can be enjoyed for its artistic value, but the desired relaxation or awakening effect on the listener cannot be achieved
Solution Approach 1:
The patent segments the audio signal into multiple frequency bands (e.g., low frequency band below 200Hz, mid frequency band 200-2000Hz, high frequency band above 2000Hz) and selectively extracts specific bands to generate vibration signals. This allows the system to process any music piece and extract frequency components that produce desired physiological effects, regardless of the music's inherent emotional content.
Solution Approach 2:
The patent changes the parameter of frequency band selection to transform the audio signal into a vibration signal with specific physiological effects. By adjusting which frequency bands are extracted and how they are processed into vibration signals, the system can induce relaxation or awakening effects from any music piece, effectively changing the output parameters to achieve desired effects.
2Loss of information
If the entire audio signal is used to generate vibration, then all information in the music is preserved, but the vibration signal becomes too complex and loses targeted effectiveness
Solution Approach 1:
The patent extracts only the necessary frequency components from the audio signal that are effective for producing relaxation or awakening effects. Specifically, it extracts low frequency components (below 200Hz) for relaxation and mid-to-high frequency components (200-2000Hz and above) for awakening, discarding other frequency components that do not contribute to the desired effects. This extraction process maintains effectiveness while reducing unnecessary information.
3Adaptability or versatility
If vibration is applied based on any music piece, then the system is versatile, but the vibration effect is inconsistent and unreliable
Solution Approach 1:
The patent dynamically adjusts the vibration signal generation process based on the characteristics of each music piece. The mode determination unit analyzes the audio signal in real-time and dynamically selects appropriate frequency bands and processing parameters, ensuring that the vibration effect remains reliable and consistent regardless of the music's tempo, genre, or emotional content.
Solution Approach 2:
The system incorporates feedback mechanisms where the mode determination unit continuously monitors the audio signal characteristics and adjusts the extraction and processing parameters accordingly. This feedback loop ensures that the vibration signal generation adapts to maintain consistent relaxation or awakening effects across different music pieces, improving reliability through continuous optimization.

AI summary
A desired effect can be exerted on the mental and physical state of a listener of a piece of music with a vibration based on the piece of music even when the piece of music has almost no relaxation or awakening effect. As a vibration signal for vibrating a vibration generation device while the piece of music is being played, the audio signal in the band corresponding to the mode is extracted from the audio signal of the music, and a vibration signal is generated based on the extracted audio signal.
