Abstract

PURPOSE: A medium playing device having a brainwave playing function is provided to fully play a brainwave signal through an exclusive speaker without increasing a voice signal in order to increase the brainwave signal by subtracting/adding only the brainwave signal depending on a deviation of each person. CONSTITUTION: A media player is equipped with a voice signal processor(140) and a voice amplifier(150) for playing a voice. A brainwave data storage stores the brain wave data generated from a human brain. A brainwave amplifier(170) amplifies the brainwave data. A synthesizer(180) synthesizes an output signal of the brainwave amplifier and the voice amplifier. A controller(200) makes the brainwave data storage apply one brainwave data to the brainwave amplifier by responding to the first control signal from the outside and controls an amplification yield by responding to the second control signal from the outside.

Description

Media player device capable of playing EEG {Media player device capable to play electroencephalogram}

The present invention relates to a medium reproducing apparatus for reproducing audio and video, and more particularly, to a medium reproducing apparatus having a brain wave reproducing function.

Clinical experiments have shown that the human brain generates different frequencies during activity, sleep, and meditation. Such frequencies are commonly referred to as brain waves, and alpha waves (α) having a frequency range of 7 kHz to 11 kHz, beta waves (β) having a frequency range of 15 kHz to 23 kHz, having a frequency range of 4 kHz to 6 kHz Theta waves θ and delta waves δ having a frequency range of 0.4 Hz to 4 Hz are known.

Alpha waves (α) appear mainly when a person meditates or when the state of mind and body is comfortable, beta waves (β) appear mainly when a person is active, and theta waves (θ) appear mainly when a person gets sleepy. Wave (δ) is a waveform that appears mainly when a human is in a sleeping state or a coma. The alpha alpha (α) has been reported to have a predetermined therapeutic effect in the modern man tired of various stress, there have been many attempts to help human activity by artificially generating alpha wave (α). In the domestic market, learning aids such as AMSC are being sold, and a video reproducing apparatus for outputting an alpha wave (α) to a speaker attached to the video reproducing apparatus when viewing a video reproducing apparatus such as a television has been disclosed.

1 is a block diagram of a conventional image display apparatus having an EEG function.

The illustrated image reproducing apparatus includes a tuner 10, an audio signal processor 20, an EEG data storage unit 30, an audio synthesizer 40, an amplifier 41, a headphone 42, and an EEG frequency pattern storage unit. 50, a video signal processor 60, a synthesizer 61, a screen 62, a key input unit 70, and an EEG state receiver 80.

The tuner 10 selects any one of the broadcast signals transmitted from the broadcast station. The voice signal processor 20 generates a voice signal by processing the broadcast signal selected by the tuner 10. The brain wave data storage unit 30 stores frequency information for generating an alpha wave α of 7 Hz to 11 Hz. The voice synthesizer 40 mixes the frequency of the alpha wave α output from the brain wave data storage unit 30 and the voice signal output from the voice signal processor 20. The amplifier 41 simultaneously amplifies the mixed voice signal and the alpha wave α according to a predetermined gain. The headphone 42 reproduces the output of the amplifying unit 41 at an audible frequency, and includes a sensor for detecting brain waves in a portion in close contact with the human brain. Accordingly, the headphone 42 transmits the EEG information obtained from the human brain to the EEG state receiving unit 80.

The EEG frequency pattern storage unit 50 includes a character for displaying the frequency of the EEG to be reproduced in the headphone 42 on the screen 62 when the human brain wave state is out of the alpha wave (α). The image signal processor 60 processes the broadcast signal received from the tuner 10 to generate an image signal. The synthesizing unit 61 synthesizes the OSD signal from the image signal and the EEG frequency pattern storage unit 50 and transmits it to the screen 62. The key input unit 70 receives a setting key (not shown) or a key input signal (not shown) generated by a remote control device (not shown) included in the image reproducing apparatus and transmits it to the microcomputer 90. Here, the key input signal is a signal for adjusting the state or volume of the screen 62 of the video reproducing apparatus. The EEG state receiving unit 80 receives the EEG information transmitted from the headphone 42 and transmits it to the microcomputer 90. The microcomputer 90 adjusts the image quality and the volume of the screen 62 and the headphones 42 according to the key input applied from the key input unit 70, and changes the EEG frequency according to the EEG information applied from the EEG state receiving unit 80. The pattern storage unit 50 is controlled to output the corresponding character among the OSD characters stored in the EEG frequency pattern storage unit 50 to the synthesis unit 61. As described above, the conventional image reproducing apparatus having a brain wave reproducing function synthesizes the voice signal output from the voice signal processing unit 20 and the brain wave (for example, alpha wave) stored in the brain wave data storage unit 30 to the headphone 42. Output As described above, when the sound signal and the brain wave (for example, the alpha wave) are synthesized and output to the headphone 42, when the volume of the brain wave data is increased, the volume of the voice signal also increases. That is, there is a problem in that it is not possible to adjust the reproduced brain waves (for example, alpha waves) according to the characteristics of each individual.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned conventional problems, and an object of the present invention is to provide a media production apparatus capable of applying brain waves of different sizes according to each individual.

Media playback apparatus having an EEG playback function shown in the tuner 110, image signal processing unit 120, screen 130, voice signal processing unit 140, voice amplifier 150, EEG signal generator 160, An EEG signal amplifier 170, a synthesizer 180, a speaker 190, a microcomputer 200, and an OSD display unit 210 are provided.

The tuner 110 selects one of the broadcast signals transmitted from the broadcast station. The voice signal processor 120 processes the broadcast signal selected by the tuner 110 to generate a voice signal and sends it to the screen 130 to be reproduced. The voice signal processor 140 generates a voice signal by processing the broadcast signal applied from the tuner 110. The voice amplifier 150 receives the voice signal and amplifies the voice signal according to a predetermined gain and outputs the voice signal to the synthesizer 180. On the other hand, the EEG signal generation unit 160 is a brain wave generated in the human brain, for example, an alpha wave having a frequency range of 7 kHz to 11 kHz, a beta wave having a frequency range of 15 kHz to 23 kHz, and 4 kHz to 6 kHz It has frequency information for theta wave having a frequency range of and generates any one of alpha wave, beta wave, theta wave, and delta wave according to the frequency information selected by the microcomputer 200. The EEG signal amplifier 170 amplifies and outputs the EEG signal generated by the EEG signal generator 160 to the synthesizer 180. Accordingly, the synthesizer 180 mixes the voice signal and the EEG signal output from the voice amplifier 150 and the EEG signal amplifier 170. Here, the voice signal and the brain wave signal mixed in the combiner 180 have different amplification degrees. Description of the degree of amplification will be described together when describing the microcomputer 200 below. The speaker 190 reproduces the voice signal and the EEG signal output from the synthesizer. At this time, since the human audio frequency is 20 kHz to 20000 kHz, the EEG signals are almost inaudible.

The microcomputer 200 controls the EEG signal amplifier 170, the OSD display 210, the voice amplifier 150, and the like in response to a control signal generated from a remote control device or a setting key provided in the media player. . Of course, the microcomputer 200 also has a control function for controlling the image quality of the tuner 110 and the screen 130 for selecting a broadcast signal.

As described above, the thickness of the human skull varies with each individual, and even if the same alpha wave α is applied to each individual, the same effect cannot be obtained. The controller 200 controls the EEG signal generator 160 in response to a control signal (not shown) generated from a remote control device (not shown) or a setting key (not shown) included in the media reproducing device to generate an EEG signal. One of the EEG signals (for example, alpha wave, beta wave, theta wave, and delta wave) stored in the unit 160 is applied to the EEG signal amplifier 170 or adjusts the amplification degree of the EEG signal amplifier 170. .

If the user operating the media player according to the present invention wants to feel relaxed by the alpha wave α, select the alpha wave α by the menu key (not shown) included in the remote control apparatus. Press the volume control key (not shown) to increase the volume of the EEG signal until you feel comfortable. At this time, the volume of the voice signal of the broadcast channel output from the voice amplifier 150 does not increase unless otherwise adjusted. Accordingly, the user can adjust the intensity of the alpha wave α required by the user while adjusting the volume output from the media player to his or her taste.

The OSD display unit 210 receives volume information of the volume of the brain wave signal applied to the microcomputer 200 from the microcomputer 200 and displays it on the screen 130.

The media playback apparatus having the illustrated EEG function includes a tuner 310, an image signal processor 320, a screen 330, an audio signal processor 340, an audio amplifier 350, a speaker 360, and an EEG signal generator. The unit 370, the EEG signal amplifier 380, the low frequency speaker 390, and the microcomputer 400 are provided.

3 is similar to that shown in FIG. 2, except that the synthesizer 180 of FIG. 2 is removed and the output of the EEG signal amplifier 170 of FIG. 2 is removed. Is reproduced by the low frequency speaker 390 as a difference. Therefore, description of the overlapping part with FIG. 2 will be omitted.

In the illustrated media reproducing apparatus having an EEG regeneration function, the EEG signal generator 370 and the EEG signal amplifier 380 for reproducing the broadcast signal and the EEG signal from the tuner 310 are completely separated. Accordingly, the reproduction frequency band characteristic of the speaker 330 has a typical 20 Hz to 20000 Hz, and the low frequency speaker 390 has a reproduction frequency band characteristic of 1 Hz to 30 Hz. As such, by using the low frequency speaker separately, the EEG signal reproduced by the EEG signal amplifier 380 may be more faithfully reproduced than when using the general-purpose speaker.

As described above, the media reproducing apparatus having the EEG regeneration function of the present invention solves the problem of increasing the EEG signal in order to increase the EEG signal by adding or subtracting only the EEG signal according to the deviation of each individual. By using dedicated speakers, EEG signals can be reproduced more faithfully.
