Earphone Frequency Modulation for Adaptive Brain Wave Induction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sound providing methods using earphones fail to effectively induce desired brain waves in users due to the use of constant frequency differences, leading to inefficiencies in focus and concentration during non-face-to-face communication.
Innovation Solution
The method involves providing sound waves with a frequency difference that automatically and cyclically changes over time, allowing for multi-segmental or gradual adjustments within specific frequency ranges to induce desired brain waves.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a constant frequency difference is used between left and right ear sound waves, then the device structure is simple, but the brain wave induction efficiency is insufficient and cannot adapt to individual user responses
Solution Approach 1:
The patent implements dynamic frequency difference adjustment where the frequency difference between left and right ear sound waves automatically and cyclically changes over time through a frequency adjuster. This dynamic adjustment allows the system to adapt to individual user responses and maintain effective brain wave induction over longer periods, resolving the contradiction between adaptability and device complexity by automating the adjustment process.
Solution Approach 2:
The patent changes the frequency parameter dynamically by automatically and cyclically adjusting the frequency difference between left and right ear sound waves within specific frequency ranges (0.5-4 Hz, 4-8 Hz, 8-12 Hz, 12-20 Hz, 25-40 Hz). This parameter change enables adaptation to individual user responses while maintaining a relatively simple device structure through automated control.
2Duration of action of stationary object
If a constant frequency difference is maintained, then the control mechanism is simple, but the duration of effective brain wave induction is limited
Solution Approach 1:
The patent employs periodic action by automatically and cyclically changing the frequency difference between left and right ear sound waves over time. The frequency adjuster cycles through different frequency ranges (0.5-4 Hz, 4-8 Hz, 8-12 Hz, 12-20 Hz, 25-40 Hz), which extends the duration of effective brain wave induction by preventing adaptation fatigue while maintaining a controlled adjustment mechanism.
3Productivity
If frequency difference changes are made automatically and cyclically, then brain wave induction efficiency is improved, but the device complexity increases
Solution Approach 1:
The patent implements self-service by enabling the frequency adjuster to automatically and cyclically change the frequency difference without requiring manual intervention. The system serves itself by autonomously adjusting frequencies within predetermined ranges to maintain effective brain wave induction, improving induction efficiency while minimizing the need for complex external control mechanisms.

AI summary
A sound providing method using an earphone set and an earphone set are provided. The sound providing method using the earphone set includes simultaneously providing a first sound wave to a left ear of a user by using a left ear earphone of an earphone set and a second sound wave to a right ear of the user by using a right ear earphone of the earphone set. There is a frequency difference between a first frequency of the first sound wave and a second frequency of the second sound wave. The frequency difference automatically and cyclically changes along with time.
