Abstract

(57) [Problem] A conventional electroencephalogram guiding device has a drawback that a state of relaxation cannot be formed because at least one of the five senses of a human has a negative effect. SOLUTION: In the electroencephalogram guiding device of the present invention, two spaced apart directional plane wave speakers driven by means for generating a sine wave of an alpha wave, a theta wave and a delta wave are positioned. The means is positioned so as to be directed at a predetermined distance from the subject's ear.

Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to an electroencephalography device, and more particularly to an electroencephalography device that applies a sine wave such as an alpha wave or a theta wave directly to the brain.

[0002]

[Prior art]

 Conventionally, it has been found from the relationship between brain waves and mental activity that changes in brain wave signals affect the mind and body. That is, a delta wave having a frequency of 4 Hz or less is in a deep sleep state, a 4 to 8 Hz theta wave is in a sluggish state, an 8 to 14 Hz alpha wave is in a relaxed state, and a 14 to 28 Hz beta wave is strained. State, gamma waves above 28 Hertz are excited.

[0003] For example, by making brain waves into an alpha wave state, the memory here also enters the subconscious, and what is learned in this state can be reproduced with the alpha wave, thereby increasing the ability, vitality, Concentration, memory, judgment, creativity, eye, persuasion, expression, thinking, action, etc. are strengthened.

[0004] For this reason, various proposals have conventionally been made to induce brain waves to be alpha waves, or to have theta waves or delta waves.

[0005] As a device for inducing an electroencephalogram, a device in which a speaker or headphones is connected to the output side of a generator for generating a sine wave which is a component of an electroencephalogram signal as disclosed in Japanese Patent Application Laid-Open No. 9-51952 is known. Have been.

[0006]

[Problems to be solved by the invention]

 However, in order to form a so-called relaxation state in which theta, alpha or delta waves flood the brain, one of the five senses of humans, namely, hearing, vision, touch, smell, and taste, is required. But it must be something that does not have a negative effect. For example, headphones are effective at stimulating hearing, but can be fatal to those who experience pressure from their touch.

[0007] In addition, if the sound with the outside world is evacuated with headphones, the subject cannot communicate with the outside world and the sound, and therefore, there is a high possibility that a complaint will be made, for example, from a family member.

[0008] Furthermore, in the case of a front-mounted system such as a general acoustic device such as a TV / radio, sound overflows into a room, which is not a private use.

The present invention has been made to eliminate the above disadvantages.

As a result of various experiments and studies, the inventor of the present invention has found that, in order to eliminate the above-mentioned drawbacks, the directional surface of the loudspeaker is correctly arranged facing the subject's ear, and the distance between the two is set at 10 °. It has been found that the relaxation state can be realized very easily by setting the height to 15 cm.

The present invention has been made based on the above findings.

[0012]

[Means for Solving the Problems]

 The electroencephalogram guiding apparatus of the present invention includes a means for generating sine waves of alpha, theta and delta waves, two directional plane-wave speakers driven by the means, and this loudspeaker. And a positioning means for directing the subject at a predetermined distance from the subject's ear.

[0013]

[Embodiment of the invention]

 Hereinafter, embodiments of the present invention will be described with reference to the drawings.

In the present invention, as shown in FIG. 1, one plane wave speaker 2 for each of right and left having high directivity is provided on the output side of a CR oscillator 1 for generating sine waves of an alpha wave, a theta wave and a delta wave. 2, and the plane wave speaker 2 is attached to, for example, both sides of the tall chair 10 as shown in FIG.

The CR oscillator 1 includes a sine wave generating circuit 3 for arbitrarily selecting and generating a sine wave having a frequency called an alpha wave, a theta wave, or a delta wave; a frequency adjuster 4; , A timer 6.

Reference numeral 7 denotes an external terminal, 8 denotes an external sound source device such as a CD player, and 9 denotes a power supply.

FIG. 3 shows the relationship between the position of the ear of the subject 11 and the plane wave speaker 2. In the present invention, the positioning arm 12 transmits the planes of the left and right plane wave speakers 2 toward the ear of the subject 11. The distance from the ear of the subject 11 to the plane wave speaker 2 is set to 10 to 15 cm.

Since the electroencephalogram guiding device of the present invention has the above-described configuration, when the subject naturally moves his / her neck, no feeling of pressure is felt, and the sound wave from the plane wave speaker 2 is transmitted to the ear of the subject 11 by the ear. It acts strongly in the direction, and becomes extremely low in the front-back direction of the subject 11.

Since the diaphragm of the plane wave speaker moves in a plane, it is easy to keep the sound pressure level within a certain range with respect to the movement of the subject's neck back and forth. When they call, the distance between the speaker and the subject is open, so it can be heard relatively easily and communication can be made.

Note that a bed or the like may be used instead of the chair 10.

[0021]

[Effect of the invention]

 As described above, according to the electroencephalogram guiding apparatus of the present invention, the feeling of pressure coming from the tactile sensation is eliminated, and it is possible for the subject to superimpose sufficient electroencephalogram and effect music to act on the subject. There is no noise.

Since the ears of the subject are not closed by the plane wave speaker 2, they can relatively easily communicate with each other by voice, do not become isolated, do not worry about the subject, sit on a chair or the like, and conduct electroencephalogram induction. Will allow you to enter the meditation frontiers.
