The present invention relates to a brain activation device.

2. Description of the Related Art In general, when the human mind or body is relaxed, the brain is quiet and inactive, but if one focuses on something, the brain is activated. It has been scientifically proved that an electroencephalogram having a frequency of 10 ± 2 Hz is emitted when the brain is actively working.

In other words, placing the brain in an activated state is a suitable state for humans to live, but it is almost impossible to activate the brain at any time when desired, so it is mechanically impossible. Devices have been developed to help with this.

However, the device developed to achieve such an object stimulates the brain by stimulating the visual sense or the auditory sense, but, for example, stimulates the visual sense or the sense of hearing by using weak energy. There are problems that the brain becomes habitually weakened, the surrounding voice cannot be heard when the ear is blocked by the device, and nothing can be seen when the eye is covered by the device.

In order to solve such a problem, a device for stimulating the brain by attaching a coil for generating an electromagnetic field of a specific frequency around the head has been proposed, and FIG. 1 shows its constituent circuit diagram. [Korean Patent Publication No. 96-623]

Referring to FIG. 1, this brain activation device is composed of a voltage control unit 1, an oscillating unit 2, and an output circuit 3.

The voltage control unit 1 includes a transformer T having a primary coil T1, a secondary coil T2, and a tertiary coil T3 having different turns ratios. The third transistor Q3 in the voltage control unit 1 has a base at the output terminal of the primary coil T1,
The collector is connected to the output end of the secondary coil T2. The first transistor Q1 and the second transistor Q2 are connected to the Darlington (Darrington) via the primary coil T1.
n), and drives the third transistor Q3. The output terminal of the tertiary coil T3 is connected to the first diode D.
1, a light emitting diode LED, resistors R1 and R2, and a potentiometer first variable resistor VR1 are connected. The base of the first transistor Q1 is connected to the variable terminal of the first variable resistor VR1 via the first Zener diode ZD1.

In the oscillator 2, the first capacitor C1 charges and discharges the voltage of the voltage controller 1. The second capacitor C2 and the second Zener diode ZD2 are connected in parallel to the first capacitor C1 via the resistor R4 and the second diode D2. Programmable Unijunction Transistor PUT (Programmable Unijunct)
In the ion transistor, the anode thereof is the resistor R5 and the second variable resistor VR2, and the gates thereof are the resistors R8 and R9.
The cathode is connected to the resistor R7 at a common connection point between them.

The output part 3 has a silicon controlled rectifier SCR, the gate of the silicon controlled rectifier is connected to the output end of the oscillator 2, and the anode is connected to a common connection point between the diode D5 and the annular coil L. .

Next, the operation of the brain activation apparatus described above will be described. First, when the power supply voltage is applied, the voltage is applied to the collector of the third transistor Q3 through the secondary coil T2 of the transformer T, and the first transistor Q1
The first transistor Q1 is turned on via the fixed bias resistor R3 connected to the base of the transformer, and a current flows through the primary coil T1 of the transformer T. As a result, the second transistor Q2 is turned on. At this time, the secondary coil T2 of the transformer T1 is
A sine wave of 12 kHz is generated and a counter electromotive force is induced in the tertiary coil T3. As a result, the third transistor Q3 is turned on, and the back electromotive force induced by the first diode D1 reversely charges the first capacitor C1.

On the other hand, when the voltage flowing through the potentiometer first variable resistor VR1 exceeds the threshold voltage set in the first Zener diode ZD1, the first Zener diode ZD1 turns off the first transistor Q1. Further, the electromotive force charged by the first capacitor C1 is stabilized by the second zener diode ZD2 and the second capacitor C2 via the resistor R4 and the second diode D2. Programmable unitransistor PUT
Is the set voltage, the resistance R5, the second variable resistance VR2
And the voltage dropped by the resistors R8 and R9 causes a sawtooth wave (4 to 2) for the silicon controlled rectifier SCR trigger.
0 Hz) signal is generated. At this time, the sawtooth wave signal is adjusted by adjusting the resistance of the second variable resistor VR2. The sawtooth signal is then applied to the gate of the silicon controlled rectifier SCR to turn on the silicon controlled rectifier SCR and bring the annular coil L into resonance, so that the first capacitor C1 is recharged by the electromotive force from the diode D5. To be done.

By such an operation, a predetermined frequency signal is generated in the annular coil L and stimulates brain cells. However, in this brain activation device, an alpha wave cannot be generated, and since the annular coil L is designed to oscillate at a continuous frequency from 1 Hz to 20 Hz, it disturbs the human brain wave. There is a problem of doing. For this reason, conventional brain activation devices have some effects on physical relaxation and regular sleep, but they cannot be expected to improve learning efficiency of students and work efficiency of workers. It was
