Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing earphones do not effectively utilize binaural beats technology to induce specific brainwave states for improved user experience during long-distance mobility.
Innovation Solution
An earphone with integrated left and right speakers, a frequency adjuster, and a wireless communicator that synchronously adjusts audio signals to create frequency differences between the ears, inducing desired brainwave states through binaural beats.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional earphones are used for long-distance mobility, then users can listen to music or audio content without disturbing others, but user fatigue increases and use experience is not improved
Solution Approach 1:
The patent applies parameter changes by adjusting the frequency parameters of audio signals sent to the left and right ears differently. The frequency adjuster modifies the external audio signal to create specific frequency differences (e.g., 4Hz, 8Hz, 12Hz) between the two ears, transforming ordinary audio into binaural beats that can induce specific brainwave states and improve user experience during long-distance mobility
Solution Approach 2:
The patent implements periodic action through the cyclic variation of frequency differences over time. The frequency adjuster automatically changes the frequency difference between the two ears in a cyclic manner, creating dynamic binaural beats that prevent auditory fatigue and maintain user engagement during extended listening periods
2Adaptability or versatility
If frequency adjuster processes audio signals for binaural beats, then brainwave induction is achieved, but device complexity increases
Solution Approach 1:
The patent applies universality by designing the frequency adjuster to handle multiple functions: it processes external audio signals from various sources (wireless communicator, audio connection port), applies different frequency adjustments for binaural beats, and outputs adjusted signals to both ears. This multi-functional design integrates binaural beats capability into the existing earphone structure without requiring completely separate systems
Solution Approach 2:
The frequency adjuster serves as an intermediary component between the audio signal source and the speakers. It receives external audio signals, processes them by creating frequency differences, and then transmits the adjusted signals to the left and right speakers, simplifying the overall system architecture while achieving binaural beats functionality
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enhances concentration, promotes relaxation, and aids in meditation by stimulating specific brainwave patterns, offering improved user experience during travel or audio consumption.
Implementation Method 1
The frequency adjuster adjusts the external audio signal to a first audio signal and then transmits the first audio signal to the left ear speaker, so that the left ear speaker emits the first sound wave. The frequency adjuster adjusts the external audio signal to a second audio signal and then transmits the second audio signal to the right ear speaker, so that the right ear speaker emits the second sound wave. A first frequency of the first sound wave and a second frequency of the second sound wave have a frequency difference.

AI summary
An earphone with binaural beats function includes a left ear speaker configured to provide a first sound wave to a left ear of a user, a right ear speaker configured to provide a second sound wave to a right ear of the user, a wireless communicator, and a frequency adjuster signally connected to the left and right ear speakers via a wire, and signally connected to the wireless communicator. The frequency adjuster receives an external audio signal from the wireless communicator, and adjusts the external audio signal to a first audio signal and a second audio signal to then transmit to the left and right ear speakers respectively, so that the left and right ear speakers emit the first sound wave and the second sound wave respectively. A first frequency of the first sound wave and a second frequency of the second sound wave have a frequency difference.
