Hereinafter, embodiments will be described with reference to the accompanying drawings. However, the described embodiments may be modified in many different forms, and the scope of the present invention is not limited by the embodiments described below. In addition, several embodiments are provided to more completely explain the present invention to those skilled in the art. The shapes and sizes of elements in the drawings may be exaggerated for clarity.

1 is a diagram illustrating an example of application of an EEG-tuned vibrator through a liquid medium according to an embodiment.

When vibrations or waves are introduced into the human body at an appropriate intensity and frequency, positive reactions are often seen.

Referring to FIG. 1, the EEG-tuned vibrator 100 through a liquid medium according to an embodiment is configured inside a water bed or a water mat 10 and can introduce vibration or waves at an appropriate intensity or frequency to the user. there is.

For example, by constructing the EEG-tuned vibrator 100 through a liquid medium inside a water bed, water mat, hydrotherapy device, water pillow, bathtub 10, etc., the liquid medium (eg, water ), a predetermined frequency may be delivered to the user. At this time, various effects may be given to the user according to the provided frequency band.

For example, by improving a normal bed for rest, the user sets the bed height according to his or her physical condition in a comfortable lying position, and the vibration of the brain wave tuning vibrator 100 through the liquid medium provided in the bed By stimulating the body, it can help treat circulatory disorders, stress and insomnia.

On the other hand, the vibrator is not limited to the medium, but when air is used as the medium, the actual transmitted energy is very weak. Therefore, vibrations or waves can be transmitted as in the present embodiment by using a liquid having a higher transmission rate than air as a medium.

That is, embodiments may provide a positive effect by introducing vibrations or waves at an appropriate intensity or frequency to a user using a water bed, a water mat, or the like.

For example, the EEG-tuned vibrator 100 through a liquid medium according to an embodiment generates vibration of an alpha wave band having a low frequency band, so that the user can easily fall asleep. In addition, the brain wave tuning vibrator 100 through a liquid medium according to an embodiment generates vibration of a beta wave band having a higher frequency band than an alpha wave in response to information about a preset wake-up time, so that the user can can be imagined easily.

On the other hand, in the brain wave tuning vibrator through a liquid medium according to an embodiment, the phenomenon that the same wave/frequency as the brain wave is propagated through the water medium can be confirmed as a ripple tank proving Huygens' principle. Since each point of the wave passing through the slit acts as a wave source and creates a spherical wave, the direction of the wave changes at the corner of the obstacle and the wave propagates behind the obstacle. The ripple tank is implemented so that this phenomenon can be easily observed, and the wave phenomena of light and sound can be confirmed as surface waves. For example, a certain frequency of the action point is transmitted along the surface of the water as a square wave through the diffraction phenomenon.

The slit 140 is configured on one side of the module 101 to allow a liquid medium to flow into or out of the module 101 .

The diaphragm 130 is configured inside the slit 140 in the module 101 to separate the liquid medium from the space of the vibrator and the diaphragm. At this time, the diaphragm 130 may be configured and accommodated in the liquid medium up to a predetermined height.
