Hereinafter, a helmet having a bone conduction vibrator of the present invention will be described in detail with reference to the accompanying drawings. In the present specification, the same or similar reference numerals are given to different embodiments in the same or similar configurations. As used herein, the singular forms "a", "an" and "the" include plural referents unless the context clearly dictates otherwise.

FIG. 2 is a cross-sectional view of an electroencephalogram measuring electrode unit FIG. 3 is a conceptual diagram illustrating a state in which the user H wears the helmet 100 shown in FIG. 1. FIG.

1 to 3, the helmet 100 includes a body 110, a bone conduction oscillator 120, an electroencephalogram measuring electrode unit 130, and a controller 140.

The body part 110 is formed to be wearable on the head of the user H of the helmet 100. 1, the body 110 may include an endothelial layer 111 and an outer skin layer 112. In addition, For example, the outer skin layer 112 is formed to surround the inner skin layer 111, and may be formed of a material having relatively higher strength than the inner skin layer 111. Although not shown in the figure, the body 110 may be configured to secure the jaws of the user H to prevent unnecessary movement of the helmet 100 while the user H is wearing the helmet 100. [ And a chin strap (not shown).

The bone conduction vibrator 120 is disposed in a certain region of the body 110 to generate vibration in the skull of the user H of the helmet 100. Here, the bone conduction refers to a conduction process of sound that is transmitted to the senses by vibrating the skull of a sound wave. 1 shows an example in which the bone conduction transducer 120 is disposed on the side surface of the body part 110 so as to be adjacent to the ear of the user H when the helmet 100 is worn. However, the position of the bone conduction transducer 120 is not limited thereto, and may be disposed on the front surface or the rear surface rather than on the side surface of the body 110. In addition, the bone conduction oscillators 120 may be arranged in a plurality of different regions of the body 110.

The electroencephalogram measuring electrode unit 130 may measure the electroencephalogram of the user H of the helmet 100 that responds to the vibration generated in the skull of the user H by the bone conduction oscillator 120, And the user H is attached to the head of the user H when the helmet 100 is worn. Here, an electroencephalogram (EEG) refers to an electrogram recorded on a scalp by a potential fluctuation occurring in a brain of a person or an animal, or a brain current caused thereby. In addition, the electroencephalogram measuring electrode unit 130 may be arranged in a configuration according to a 10-20 system, for example, as shown in FIG.

The control unit 140 controls the electroencephalogram vibrator 120 and the electroencephalogram measuring electrode unit 130 so that the electroencephalogram vibrator 120 and the electroencephalogram measuring electrode unit 130 are installed in one area of the body unit 110, And receives information of the electroencephalogram and calculates the intention of the user H at present. The controller 140 may be a micro controller unit (MCU), for example. The controller 140 may also be connected to the bone conduction transducer 120 to control the operation of the bone conduction transducer 120.

At least one of the bone conduction transducer 120, the electroencephalogram measuring electrode unit 130 and the control unit 140 is disposed on the endothelial layer 111 of the body 110 and is formed to be surrounded by the outer skin layer 112 . The outer layer 112 is made of a material having a strength higher than that of the endothelial layer 111 to protect the bone conduction transducer 120, the electroencephalogram measuring electrode unit 130 and the control unit 140 from the external environment.

When the body 110 is worn on the user's head, the endothelial layer 111 is deformed toward the outer layer 112 by the user's head, and then the endothelial layer 111 is stretched. The electroencephalogram measuring electrode unit 130 and the bone conduction transducer 120 can be brought into close contact with the user's head by the restoring force of the elastic material of the user.

According to the structure of the present invention described above, the body 110, the bone conduction transducer 120, the electroencephalogram measuring electrode unit 130, and the controller 140 for BCI implementation are all worn on the head of the user H The helmet 100 is mounted on the body 110 and the brain electrode measuring electrode 130 is attached to the head of the user H when the helmet 100 is worn. And the procedure for using the helmet 100 to which the BCI technology is applied can be greatly simplified compared to the conventional method. In addition, the bone conduction transducer 120, which causes the skull to vibrate, can be effectively used in situations where tightness and quietness are highly required, such as military activities.

The helmet 100 having the bone conduction transducer 120 may further include a pressing unit 150.

The pressing portion 150 is disposed between the inner layer 111 and the outer layer 112 of the body 110 to press the inner layer 111. Here, the electroencephalogram measuring electrode unit 130 may be disposed in the endothelial layer 111 so as to be pressed by the pressing unit 150 and brought into close contact with the head of the user H. Also, although not shown in the figure, the electroencephalogram measuring electrode unit 130 may be arranged in a form fixed to the pressing unit 150 itself, not the endothelial layer 111. [ For example, the pressing portion 150 may be formed of a spring device (not shown) configured to press the endothelial layer 111 toward the head of the user H.

Further, the pressing portion 150 may include the tube 151 and the pump portion 152.

The tube 151 may be formed to correspond to an area where the electroencephalogram measuring electrode unit 130 is disposed, and may be made to expand by a fluid injected into the tube 151. For this purpose, the tube 151 may be made of an elastic material such as rubber and silicone, and may have an internal space (not shown) into which the fluid flows. In this figure, the state before the fluid is injected into the tube 151 is shown.

The pump unit 152 is connected to the tube 151 to adjust the amount of fluid to be filled in the tube. The pump unit 151 may be configured to suck or compress fluid using a pressure action.

Meanwhile, the pressing unit 150 may further include a first sensor unit (not shown) or a second sensor unit (not shown).

For example, the first sensor unit may include a pressure sensor for sensing a pressure. Accordingly, the degree of expansion of the tube 151 can be adjusted by setting a pressure value that is appropriately attached to the head of the user H by the electroencephalogram measuring electrode unit 130.

The second sensor unit may include a sensor for sensing whether the body part 110 is worn on the inside of the body part 110 to detect whether the body part 110 is worn on the head of the user H, A pressure switch may be arranged to sense pressure by the head.

For example, the second sensor unit may be an illumination sensor for sensing intensity or amount of ambient light. Accordingly, when the user H wears the helmet 100, the second sensor unit can automatically detect whether the user H wears the helmet 100 and operate the pump unit 152.

According to the structure of the pressing unit 150 described above, the electroencephalogram measuring electrode unit 130 including at least one electrode is attached to the head of the user H of the helmet 100 without lifting, The reliability of the measurement of the EEG response caused by the EEG can be further improved.
