[Industrial applications]

この考案は、脳波増強装置に関し、特に、α波脳波を強化するための脳波増強装置に関するものである。 The present invention relates to an electroencephalogram enhancing device, and more particularly to an electroencephalogram enhancing device for enhancing α-wave electroencephalogram.

[Prior art]

個人の知能活動を活性化するためには、脳波のうちα波を強化することが有効であるといわれている。従来、α波を強化する手段は数多くあるが、大部分は思念、行（ぎょう）、瞑想などにより精神統一を行って内的にα波の強化を図る訓練によるものであった。この方法は体得に時間がかかり、コツをつかむのが困難なことがあり、とくに懐疑的人間には適用し難い欠点があった。 It is said that it is effective to reinforce the alpha wave in the electroencephalogram in order to activate the intelligence activity of the individual. Conventionally, there are many ways to strengthen α waves, but most of them have been based on the practice of strengthening α waves internally by carrying out mental unification through thought, deeds, and meditation. This method takes a long time to acquire, and sometimes it is difficult to grasp the knack, and it has a drawback that it is difficult to apply, especially to a skeptical person.

【０００３】また、α波を強化するアクティブの方法として、約１５０Ｈｚのステレオ信号（音声）の双方に、個人の固有α周波数の周波数差を与え、頭脳内でα周波数のビートを発生させるものがあり、相応の効果が確認されている。この方法は特許第１５９９９６８号により周知である。これは、ステレオ信号の一方を略１５０Ｈｚの正弦波信号とし、他方をα周波数だけ異なった信号として同時に両耳で聴取させる。α周波数は個人差があるが、９〜１３Ｈｚ程度の範囲内にある。上記の両耳聴取により、脳内でα周波数の左右両脳の干渉がおこり、その結果、α周波数の脳波、すなわちα脳波が強化されるとされている。Further, as an active method for strengthening the α wave, there is a method of giving a frequency difference of an individual α frequency of an individual to both of stereo signals (voices) of about 150 Hz to generate a beat of the α frequency in the brain. Yes, and the corresponding effects have been confirmed. This method is known from Japanese Patent No. 1599968. This allows one of the stereo signals to be a sine wave signal of approximately 150 Hz, and the other to be simultaneously heard by both ears as signals differing by the α frequency. The α frequency is within the range of about 9 to 13 Hz, though there are individual differences. It is said that the above-mentioned binaural hearing causes interference between the left and right brains of the α frequency in the brain, and as a result, the electroencephalogram of the α frequency, that is, the α brain wave is strengthened.

[Problems to be solved by the device]

以上のようなビート方式による従来の脳波増強装置は、α脳波強化の効用は認められているが、信号音が１５０Ｈｚの持続信号であって、快適な音色とはいえず、不快や疲労を感じることもあり、飽き易いという問題点があった。また、α 周波数だけ異なる２つの信号を安定して発生させる装置は電子回路がやや高度で、コストが上昇し、電池の消耗も増大するなどの問題点もあった。 Although the conventional electroencephalogram potentiator based on the beat method as described above is recognized to have the effect of enhancing α electroencephalogram, the signal sound is a continuous signal of 150 Hz, which is not a comfortable timbre and causes discomfort or fatigue. There was a problem that it was easy to get tired of because of the feeling. In addition, the device for stably generating two signals differing only in α frequency has a problem that the electronic circuit is rather sophisticated, the cost increases, and the battery consumption increases.

【０００５】この考案はかかる問題点を解消するためになされたもので、快適にα脳波の強化を達成することができ、かつ、低コストで電池の消耗も少ない脳波増強装置を得ることを目的とする。The present invention has been made in order to solve the above problems, and an object of the present invention is to obtain an electroencephalogram enhancer capable of comfortably achieving α electroencephalogram enhancement, low cost, and low battery consumption. To aim.

[Means for Solving the Problems]

この考案にかかる脳波増強装置は、音楽音などのステレオ信号の双方に個人の α波脳波の固有周波数で互いに逆位相の振幅変調をかける１対の変調器と、変調されたステレオ信号を聞かせるためのヘッドホンとを備えており、振幅変調の適用周波数範囲を音声帯域のうら１ＫＨｚ以下としたものである。 The electroencephalogram enhancer according to the present invention allows a pair of modulators that perform amplitude modulation of opposite phases to each other on a stereo signal such as a music sound at the natural frequency of an individual α-wave electroencephalogram and a modulated stereo signal. It is equipped with headphones for use, and the applicable frequency range of amplitude modulation is 1 kHz or less in the back of the voice band.

[Action]

この考案においては、ステレオ信号の相互干渉を活用するものであるが、信号を特定せず、一般のステレオ信号、たとえば音楽音、ナレーションなどをそのまま用いる。これにより対象個人は、自分の聞きたい信号でα波を増強する。 In this invention, mutual interference of stereo signals is utilized, but general stereo signals such as music sounds and narration are used as they are without specifying the signals. As a result, the target individual enhances the α wave with the signal he / she wants to hear.

【Example】

以下、この考案の一実施例を図１、図２について説明する。図１において、ステレオ信号源（図示せず）から入力Ｒ、Ｌにステレオ信号が与えられる。ステレオ信号としては、一般の音楽音、自然音、ナレーションなどから適宜に選ぶものとする。この入力信号はそれぞれ低域フィルタ（ＬＰ）２０、２１を通して変調器（ＡＭ）１、２に加えられる。一方、入力信号のうち高域フィルタ（ＨＰ）２２、２３を通った信号はそのままミキサ（ＭＩＸ）２４、２５で変調器１、２よりの出力とミクスされ、それぞれベッドホン３、４に加えられて音響出力に変換される。低域フィルタ２０、２１、高域フィルタ２２、２３の遮断周波数は２００Ｈｚから１ＫＨｚの範囲とする。個人のα波脳波固有周波数（９〜１３Ｈｚ）の発振器（ＯＳＣ）５の出力は、一方はそのまま変調器１に加え、他方は位相反転器（ＩＮＶ）６を経て変調器２に加える。 An embodiment of the present invention will be described below with reference to FIGS. In FIG. 1, a stereo signal is applied to inputs R and L from a stereo signal source (not shown). The stereo signal shall be appropriately selected from general musical sound, natural sound, narration, and the like. This input signal is applied to modulators (AM) 1 and 2 through low pass filters (LP) 20 and 21, respectively. On the other hand, of the input signals, the signals that have passed through the high-pass filters (HP) 22 and 23 are mixed as they are with the outputs from the modulators 1 and 2 by mixers (MIX) 24 and 25, and added to the bedphones 3 and 4, respectively. Is converted into acoustic output. The cutoff frequencies of the low-pass filters 20 and 21 and the high-pass filters 22 and 23 are in the range of 200 Hz to 1 KHz. The output of the oscillator (OSC) 5 of the individual α-wave brain wave natural frequency (9 to 13 Hz) is applied to the modulator 1 as it is, and the other is applied to the modulator 2 via the phase inverter (INV) 6.

【０００９】この装置の両出力の波形を図２に示す。変調器１、２によって両出力の波形は振幅変調をうけ大きさが変動するが、その大小関係は両出力間で相補となる。被変調波すなわち両入力信号は主として非定常非周期信号であり、図では母音の場合を示している。The waveforms of both outputs of this device are shown in FIG. The amplitudes of the waveforms of both outputs are varied by the modulators 1 and 2, and the magnitudes thereof are changed, but the magnitude relationship is complementary between both outputs. The modulated wave, that is, both input signals are mainly nonstationary aperiodic signals, and the figure shows the case of vowels.

【００１０】振幅変調の変調度が大きいとき、信号音の高域音、たとえば拍手音、波の音、楽器音などに対して変調効果が耳ざわりで、時には不快を感じることがある。これを解消するため、入力信号をフィルタで分割し、低域フィルタ２０、２１を通った低域音のみに振幅変調をかけ、高域フィルタ２２、２３を通った高域音は変調をかけずにそのまま用いることにする。以上のようにして、どんな音信号を用いても不快感や疲労がなく、また、α波増強効果に有効なのは音信号のうち低域成分のみであるから、α波増強効果は減じることはない。When the degree of modulation of the amplitude modulation is high, the modulation effect is harsh for high-frequency sounds of signal sounds, such as clapping sounds, wave sounds, and instrument sounds, and sometimes the user feels uncomfortable. In order to eliminate this, the input signal is divided by a filter, amplitude modulation is applied only to the low-frequency sound that has passed through the low-pass filters 20 and 21, and the high-frequency sound that has passed through the high-pass filters 22 and 23 is modulated. I will use it as it is without applying. As described above, any sound signal is used without causing discomfort or fatigue, and only the low frequency component of the sound signal is effective for the α-wave enhancement effect, so the α-wave enhancement effect should be reduced. There is no.

[Effect of device]

この考案は、以上の説明から明らかなように、個人のα脳波周波数でステレオ信号の双方に互いに逆位相の振幅変調をかけて聞かせるようにしたので、α脳波の増強が快適のうちに達成される。また、振幅変調の適用周波数範囲を１ＫＨｚ以下とすることにより、どのような音声信号を用いても不快感がなく、α脳波増強効果の大きい装置を得ることができる。さらに、一般的な素子で構成することができるので、市販のポケット型ヘッドホンテープレコーダに容易に内装することもでき、低コストで電池の消耗も少なくできる。 As is clear from the above description, this device is designed to allow both stereo signals to be subjected to amplitude modulation in opposite phase to each other at the individual α brain wave frequency, so that enhancement of α brain wave can be achieved comfortably. To be done. Further, by setting the applied frequency range of amplitude modulation to 1 KHz or less, it is possible to obtain a device that has no discomfort even if any audio signal is used and has a large α brain wave enhancing effect. Further, since it can be configured with general elements, it can be easily installed in a commercially available pocket-type headphone tape recorder, and the cost can be reduced and the battery consumption can be reduced.
