Embodiment 1

[0024] Embodiment 1, a kind of device that realizes the method of the present invention, its circuit principle block diagram is as follows figure 1 As shown, it includes audio signal input, channel separation circuit part, switch circuit, amplifier circuit and output terminal; the input audio signal is sent to the serial connection after being processed by high-pass filter and low-pass filter in the signal input part. The channel separation circuit part, according to the control command of the playback controller, divides the input audio signal into the audio signal of the main channel and the auxiliary channel after frequency difference processing and / or phase processing, and outputs them respectively via the left and right channels To the input end of the switch circuit, at this time, the audio signals on the main and auxiliary channels are respectively high and low frequency and / or audio signals (different in positive and negative polarity), respectively through the switch c...

Embodiment 2

[0026] Embodiment 2 of the present invention, its circuit principle block diagram is as figure 2 As shown, in this embodiment, the method and working principle and process it adopts are basically the same as those in Embodiment 1, the difference is that in this embodiment, the controller controls the stored audio processing The audio files in the built-in memory in the circuit are coded / decoded to generate new audio files, and the separation and phase and frequency processing of the main and auxiliary channels are realized by software, and are saved in a new format, and then connected to the The output circuit on the audio processing circuit and the switch circuit on it output in the same control mode as that of the first embodiment.

Abstract

The present invention discloses a method for inducing brain wave synchronization. Said method includes the following steps: (1), according to the set EEG frequency required for induction making left-right sound channel short-sound reciprocally-stimulated period and working frequency, the reciprocal working frequency is 5-40H2; (2), separating the inputted audio signal into main and auxiliary sound channels; (3), utilizing defined reciprocal working frequency to control main and auxiliary sound channels and respectively alternatively switch them into left ad right sound channels, and alternatively playing the audio signal modulated by step 2. Said invention also provides a device for implementing said method, said device includes the components of sound channel separation circuit, switching circuit and playing controller, etc.

Description

technical field [0001] The invention relates to a brain wave induction technology, and mainly relates to a method and a device for inducing brain wave synchronization by using left and right short sound interactive stimulation methods. Background technique [0002] Modern medicine's scientific research on the auditory drive of brain waves shows that when the brain is stimulated with sound, such as rhythmic ticks, tones or noise vibrations, EEG is used to monitor the brain, and it is found that the brain does increase at the same frequency as the sound. Brain activity in response to rhythmic auditory stimuli. [0003] Researchers have found that when our brain enters the alpha state, our body produces some beneficial substances, blood pressure becomes normal, pulse becomes stable, tense body organs are relaxed, and our body is full of vitality again. And I think this is also the best learning state. Scientists believe: "Using the principles and means of physics to study and...
