Abstract

A brain wave induction method is provided. In the method, a first sound wave to a left ear of a user and a second sound wave to a right ear of the user are simultaneously provided. 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 is automatically changed along with time.

Claims (16)

1 . A brain wave induction method, comprising:

simultaneously providing a first sound wave to a left ear of a user and a second sound wave to a right ear of the user, wherein there is a frequency difference between a first frequency of the first sound wave and a second frequency of the second sound wave, and the frequency difference is automatically changed along with time,

wherein the frequency difference is changed back and forth between 0.5 Hz and 4 Hz, between 4 Hz and 8 Hz, between 8 Hz and 12 Hz, or between 12 Hz and 20 Hz,

wherein the first sound wave and the second sound wave are respectively provided to the left ear and the right ear of the user through an earphone.

2 . The brain wave induction method according to claim 1 , wherein the frequency difference is changed multi-segmentally along with time.

3 . The brain wave induction method according to claim 1 , wherein the frequency difference is remained unchanged for 5 seconds to 120 seconds after each change.

4 . The brain wave induction method according to claim 1 , wherein a change amount of each change in the frequency difference is 0.1 Hz, 0.2 Hz, 0.5 Hz, or 1 Hz.

5 . The brain wave induction method according to claim 1 , wherein a change amount of each change in the frequency difference is between 0.1 Hz and 1 Hz.

6 . The brain wave induction method according to claim 1 , wherein the frequency difference is reduced by 0.1 Hz each time.

7 . The brain wave induction method according to claim 1 , wherein the frequency difference is remained unchanged for 16 seconds after each change.

8 . The brain wave induction method according to claim 1 , wherein the earphone has an active noise cancellation function.

9 . The brain wave induction method according to claim 1 , wherein the earphone is a wireless earphone.

10 . The brain wave induction method according to claim 1 , wherein the earphone is a Bluetooth earphone.

11 . The brain wave induction method according to claim 1 , wherein after respectively providing the first sound wave and the second sound wave to the left ear and the right ear of the user for a predetermined time, provision of the first sound wave and the second sound wave is automatically stopped.

12 . The brain wave induction method according to claim 1 , wherein the first sound wave and the second sound wave are respectively generated after performing a frequency adjustment on a self-selected audio of the user.

13 . The brain wave induction method according to claim 1 , further comprising: providing a first background sound wave to the left ear of the user and a second background sound wave to the right ear of the user while providing the first sound wave and the second sound wave, wherein the frequency difference is provided between a third frequency of the first background sound wave and a fourth frequency of the second background sound wave.
