Human sleep is very closely related to EEG. Depending on the activity of the brain, brain waves can be classified into alpha waves (7-14 Hz), beta waves (14-30 Hz), delta waves (0.5-4 Hz), and theta waves (4-8 Hz). When the arousal level is too high, the beta wave usually appears, when the sleep or sleep is mainly delta wave, and when the awakening level is not too high or too low may appear alpha or theta wave.

According to the type of brain waves, sleep is divided into REM (Rapid Eye Movement) sleep and non-REM sleep, and non-REM sleep is generally divided into four stages according to the depth of sleep. It may be reclassified.

As shown in FIG. 1, the first sensor part S1 and the second sensor part S2 may be disposed on both sides of the cover part 110, but the present invention is not limited thereto. The first and second sensor units S1 and S2 may include an illuminance sensor for measuring illuminance of a user's surrounding environment, a temperature sensor for measuring an external temperature, a humidity sensor for measuring an external humidity, and the user generating during sleep It may include a microphone for measuring sound or external sound, a motion sensor for acquiring a user's movement, and the like. In addition, the first and second sensor units S1 and S2 may further include an acceleration sensor, a gyro sensor, a magnetic sensor, a gravity sensor, and the like.

Referring to FIG. 2, the third sensor unit S3 and the output units 161 and 162 may be disposed on the elastic unit 150 (that is, the inner surfaces of the housing units 110 and 150).

The third sensor unit S3 may be located at the center of the upper end of the elastic unit 150. However, this is only one example and the present invention is not limited thereto.

The first output unit 161 may be located at one side of the elastic unit 150 and output a sound or a light source having a first frequency. The second output unit 162 may be located at the other side of the elastic unit 150 to output a sound or a light source having a second frequency different from the first frequency.

The output units 161 and 162 may include speaker units SP1 and SP2 for outputting sound and light source units L1 and L2 for generating light. However, the present invention is not limited thereto, and the output units 161 and 162 may stimulate at least one of the five senses of the user through at least one of vibration, sound, light, taste, and aroma. For example, the output units 161 and 162 may further include a fragrance output unit for spraying a substance containing fragrance and a vibration output unit for generating vibration.

The speaker units SP1 and SP2 may include a first speaker SP1 that outputs a first frequency and a second speaker SP2 that outputs a second frequency whose difference from the first frequency is a first wavelength. Can be. For example, the first speaker SP1 may be located at the upper left of the housing parts 110 and 150, and the second speaker SP2 may be located at the upper right of the housing parts 110 and 150. However, the present invention is not limited thereto.

In detail, the first speaker SP1 and the second speaker SP2 may simultaneously output sound waves having different frequencies, thereby inducing a brain wave or a sleep state of the user. In general, human audible frequencies range from 20Hz to 20kHz. Human brain waves (for example, alpha waves (7-14 Hz), beta waves (14-30 Hz), delta waves (0.5-4 Hz), theta waves (4-8 Hz)) are all below the audible frequency (<20 Hz). Because of the frequency, the general method cannot deliver the desired frequency to the brain (in contrast, if light is arbitrarily set to the stimulus corresponding to the sleep stage in the case of light, electroencephalogram may occur accordingly).

Therefore, the sleep induction apparatus 100 of the present invention may induce an EEG by using a binaural beat. When the sound waves of different frequencies are delivered to both ears of the human, the brain uses a principle that the frequency corresponding to the frequency difference of the sound waves delivered to each ear is transmitted. Detailed description thereof will be described later with reference to FIG. 9.

In addition, the speaker units SP1 and SP2 may be used to remove external noise. For example, when noise occurs in a room, the speaker units SP1 and SP2 may cancel the noise by providing a sound wave having a frequency opposite to that of the noise.

That is, the first light source L1 may be irradiated to the left eye of the user, and the second light source L2 may be irradiated to the right eye of the user. However, the present invention is not limited thereto. The first light source L1 and the second light source L2 may be composed of one or more LEDs or light emitters.

The first light source L1 may output a light source having a first frequency, and the second light source L2 may output a light source having a second frequency. The light source units L1 and L2 may use the principle of the stereoscopic beat described above. In this case, the light intensity, color change, and illuminance change of the light sources L1 and L2 may be changed based on the first frequency and the second frequency. For example, the volume of the sound may correspond to the intensity of the light of the light sources L1 and L2, and the change in the type of sound may correspond to the change of the color of the light of the light sources L1 and L2. In addition, the light sources L1 and L2 may use a color that has the greatest influence on inducing sleep of the user for output. However, the present invention is not limited thereto.

5 is a graph illustrating an example of a general sleep stage.

Referring to FIG. 5, the general sleep stage may be classified into one to four stages according to the generated brain waves. During the early stages of sleep (e.g., about 3 hours after the start of sleep), you can move between deep and shallow non-remem sleeps step by step, and the amount of REM sleep can increase as sleep time continues. In general, the human being hard to wake up in the middle of the REM sleep state 110 may feel unpleasant, but when waking from the end of the REM sleep 120 may feel a refreshing with relatively little unpleasantness.

In addition, each stage of sleep has its own necessary functions, and mental or physical problems can occur if too few or too many specific stages occur (cardiovascular disease, diabetes, dementia, etc.). Therefore, the quality of sleep can be improved by inducing the sleep stages proportionally and reducing the wake-up during sleep so that the sleep function can be properly performed according to the sleep cycle of the individual. For example, if the ratio of Deep Sleep: REM: Shallow Sleep is 1: 2: 1 (25%: 50%: 25%) is the ideal ratio, the ratio can be maintained while the user is sleeping. , The sleep inducing apparatus of the present invention can induce the sleep stage of the user.

Depending on the stage of sleep, brain waves are different, and changes in the body may also appear in different stages of sleep. Sleep stages include subject's biometric information (e.g., EEG, heart rate, respiration, blood oxygen saturation, retraction, snoring, eye movements, muscle movements, body temperature, etc.) and environmental information (e.g., noise, light, Temperature, humidity, etc.). By measuring the subject's biometric and environmental information, it is possible to find a sleep pattern indicating a change in sleep stage while the subject is sleeping.

In addition, a change in the sleep state may be induced by applying an external stimulus through the sensory organ of the subject. For example, when sound or a light source of a specific frequency is transmitted to the brain through the sensory organs, the sleep state may be changed to the sleep stage corresponding to the specific frequency (brain wave tuning theory).

The sleep induction apparatus 200 of the present invention may induce a sleep state to measure a sleep state of a user and adjust an output frequency according to the sleep state of a user to be close to an optimal sleep pattern. For example, if sleep is difficult, sleep induction may be performed to quickly wake up, or a desired form of sleep brain waves may be continuously induced to prevent waking in the middle of sleep. In addition, the ratio between REM sleep and non-REM sleep can be adjusted. Through this, the sleep induction apparatus 200 of the present invention may allow the user to take a good night's sleep and induce the user to wake up with a refreshing mood.

6 is a graph illustrating a method of maintaining and changing a user's sleep state in a sleep induction device according to some embodiments of the present disclosure.

Referring to FIG. 6, the sleep guidance apparatus according to some embodiments of the present disclosure may determine the sleep state of the user by acquiring the body information and the surrounding environment information of the user detected through the sensor unit. In the graph of FIG. 6, the horizontal axis corresponds to time and the vertical axis corresponds to the depth of the water surface.

First, in order to allow the user to enter the initial sleep state from the awake state, the sleep stage may be reduced (step 310). In this case, the controller 230 may adjust the output signal of the output unit 220 according to the response rate of the brain wave tuning of the user. For example, the EEG signal applied to the user may be reduced in the order of 25 Hz-> 12 Hz-> 5 Hz-> 2 Hz to 0.5 Hz. However, the present invention is not limited thereto.

Subsequently, after the user reaches the deep sleep stage, the stimulus for the corresponding frequency band (eg, delta wave) is continuously maintained (step 320) so as to stay in the deep sleep stage at a preset ratio. The data regarding the ideal sleep pattern and the change in the sleep stage may be stored in the memory 250 in advance. The controller 230 may adjust a ratio between deep sleep (or non-remem sleep) and shallow sleep (or rem sleep) based on the data stored in the memory 250.

If the sleep phase is not continuously induced by the output signal and changes naturally to shallow sleep (or REM sleep) through the EEG, the stimulus may be stopped after a predetermined time or a predetermined number of induction stimuli. Can be. Subsequently, if a shallow sleep (or REM sleep) entry is required, an output signal may be applied to the user to arbitrarily enter a shallow step (step 330).

Subsequently, when the state of reaching the stage of the shallow sleep (or REM sleep) is detected (step 340), the stimulus may be applied again to be guided to the lower deep sleep according to the individual sleep cycle. (350 steps).

In other words, if there is a change to go from a deep sleep state to a shallow sleep state, try additional trials according to a predetermined schedule, and if the effect no longer appears, the stimulus may be temporarily changed to change the sleep stage. Stop. Then, when a point no longer descends into the sleep phase (e.g., REM sleep), it stimulates the frequency band to maintain REM sleep (step 340) or reenters deep sleep. May be applied again (step 350).

If the process is repeated during sleep and wakes up, the user may wake up the user by adjusting the frequency, intensity, color change, temperature, etc. of stimulating the user's sensory organs (step 360). Through this, the sleep guidance device can provide the user with an optimal weather condition. However, the present invention is not limited thereto, and the sleep state change described above is exemplary and may be variously set according to a situation.

7 is a view for explaining an induction technique according to the brain wave tuning method of the sleep induction apparatus according to an embodiment of the present invention.

Referring to FIG. 7, in order to maintain or change the sleep state of the user, the controller 230 controls the output unit 220 to generate an output signal reflecting feedback based on the current sleep state and the desired sleep state of the user. Can be.

In detail, the sleep state of the user may be changed by being affected by the wavelength transmitted to the human brain. In this case, in order to transmit the frequency of the wavelength corresponding to the desired sleep state to the brain, the controller 230 may transmit the output signal of the corresponding frequency to the brain through the output unit 220 in a binaural beat method. In this case, the 3D sound beat method uses a principle in which wavelengths corresponding to frequency differences of different sounds transmitted to the left and right ears are transmitted to the brain. Therefore, by transmitting sounds of different frequencies to both ears, it is possible to transmit a signal of the wavelength desired by the user to the brain. For example, a sound of a first frequency (for example, 100 Hz) is output to one ear through the left first speaker SP1, and a second frequency (for example) to the other ear through the second speaker SP2. , By outputting a sound of 110Hz), a signal having a wavelength of 10Hz can be transmitted to the brain. In the case of a light source, it may be applied to achieve brain wave tuning by using a specific wavelength, light intensity, color change of light, or color temperature of light. However, the present invention is not limited thereto.

8 is a view for explaining an operation method of the sleep guidance device according to some embodiments of the present invention.

Referring to FIG. 8, FIG. 8 illustrates a sleep cycle of a user. On the graph, the first sleep pattern, which is a high quality sleep cycle, is indicated by a solid line, and the second sleep pattern, which is a low quality sleep cycle, is shown by a dotted line.

In the second sleep pattern, it takes a long time to reach an initial sleep state, does not reach a deep sleep state, and mainly stays only in a shallow sleep state. In addition, the user frequently wakes up while sleeping, and when the user sleeps in the second sleep pattern, the user wakes up with tiredness.

On the other hand, in the first sleep pattern, the period between the shallow and deep sleep stages is constant, the time taken to reach the deep sleep state is relatively short, and the ratio of the deep sleep state to the shallow sleep state remains constant. do.

The sleep induction apparatus 200 according to the present invention continuously applies an output signal having a constant wavelength to the user, grasps a change in the sleep state of the user, and adjusts the output signal so that the user takes a sleep close to the first sleep pattern. Can be.

In order to achieve more efficient EEG, the response rate of the user's sleep state (ie, EEG response rate) may be measured, and the rate of change of the output signal may be adjusted based on the response rate. For example, a user who has a slow response time in sleep state may apply a wider range of stimulus changes to reach a desired sleep stage in a short time.

In addition, in order to improve the quality of sleep, the user can accurately analyze the change in response to external stimuli and adjust the sleep stage in consideration of this. Specifically, in order to reduce the elevation time (the time it takes to go to sleep after going to bed) and to fall asleep deeply, the individual sleep according to the external stimulus (for example, by adjusting the air conditioner among the peripheral devices to change the temperature, etc.) Analyze trends in phase status. Then, depending on the degree of response of the user to external stimuli, the stage of sleep can be optimized and induced from the low stage (awake state or shallow sleep stage, beta / alpha increase) to the deep stage (deep sleep, delta wave increase). Can be. In other words, through the analysis of the complex correlation of various biological signals, not just the EEG, it is possible to actually improve the sleep state together with the most efficient EEG.

For example, in the case of the control of sound waves, when the current sleep brain wave is induced at a low frequency level of 17 Hz to 2 Hz, the difference is continuously lowered by 1 Hz, and the change of 1 Hz is not induced from the high frequency to the low frequency. The time taken to reach an approximate value (+,-specific value, for example 0.3 Hz) similar to 16 Hz when is given is measured. The degree of stimulation can be adjusted according to the time it takes to reach the set target approximation. In other words, by applying a stimulus to broaden or narrow the change according to the response rate of the EEG, in practice, the overall elevation time is reduced to the minimum that is optimally matched to the individual EEG response rate. Allows you to reach sleep (low frequency range).

The output signal that stimulates the user is not only wide or narrow like sound waves, but also strong or weak intensity such as light, temperature, fragrance, humidity, touch, change of color, change of temperature, degree of pressure, etc. Scheme control pattern may be used. The individual stimulation degree control method according to the EEG response rate can be applied not only to the elevation time, but also to the stimulation method to keep awake and wake up after falling asleep.

In addition, the user may wake up through various alarm types after comprehensively analyzing the bio signal and surrounding environment information to determine an optimal timing for waking up. Light is recommended to be exposed to the time of day necessary for the body's healthy periodic activities (eg, melatonin production), and to emit light in the eye products that are provided even when waking up in the morning (lights, indoor lighting, Stand lighting, etc.) can be a strong exposure to wake up healthy and effective. At this time, the exposed light does not merely expose a single light of uniform brightness uniformly, but the bio signal according to the stimulus in a manner suitable for an individual such as light color (yellow, blue, etc.), brightness, flickering (frequency), etc. The response can be provided in a way that the product determines as it is constantly learning and wakes up most comfortably. In addition, in the case of other stimulation sources (sound, fragrance, touch, temperature, etc.) can be provided in a variety of forms by learning a specific pattern stimulus to enable each user to wake up without most inconvenience. For example, the sound may be provided with a time plan so that the user feels the most preferred and comfortable sound gradually from a small state to a high state and gradually wakes up on a shallow surface. For example, when the user is switched from the sleep state to the awake state, the external stimulus may be gradually adjusted to move to the optimal sleep cycle. However, the present invention is not limited thereto.
