{NOTIFICATION DEVICE FOR THE DEAF PERSON}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a notification device for a hearing impaired person, and more particularly to a notification device for a hearing impaired person who informs a hearing impaired person of the kind of sound.

While entering the 21st century information age, many people have come up with advanced technologies. On the contrary, technologies for social disadvantaged people such as the disabled and the elderly are developing more slowly than those made by the general people.

In particular, hearing-impaired people often perceive situations that are happening in their surroundings with only sight, so they are not aware of what is going on in situations that are beyond their scope.

In addition, even if the situation occurs within the scope of vision, the situation will not be accurately recognized when the situation is static rather than dynamic.

As such, it is a reality that the hearing-impaired person has a remarkable ability to recognize the situation in daily life, but the development of a separate device for recognizing such situation is not performed so much, It is no exaggeration to say that they are living in a situation where they hardly know about the situation in their lives.

In other words, since the hearing-impaired person can not hear the sound well, it is not only impossible to receive TV or telephone, but also can not recognize a fire alarm, a horn sound of a vehicle, a siren sound or a falling sound, .

In particular, there is a concern that a hearing impaired person may not be immediately aware of an emergency situation because of not recognizing a fire alarm that sounds at the time of a fire, which could lead to life-threatening situations.

Therefore, a fire alarm for the hearing impaired has been developed. However, this is a visual alarm which can be used only indoors, and it is installed on the wall of the room where the hearing impaired person resides. Therefore, when the hearing impaired person is not in the room, .

That is, in the case of the conventional technology, since the hearing-impaired person always has to be around the notification device, it can not be used outdoors.

3 is a diagram illustrating an exemplary screen of a portable terminal of a notification device for the hearing impaired according to an exemplary embodiment of the present invention.

Hereinafter, a notification device for a hearing impaired person according to an embodiment of the present invention will be described with reference to the accompanying drawings. In this process, the thicknesses of the lines and the sizes of the components shown in the drawings may be exaggerated for clarity and convenience of explanation. In addition, the terms described below are defined in consideration of the functions of the present invention, which may vary depending on the intention or custom of the user, the operator. Therefore, definitions of these terms should be made based on the contents throughout this specification.

FIG. 1 is a block diagram illustrating a notification device for a hearing impaired person according to an embodiment of the present invention. FIG. 3 is an exemplary view of a screen of a mobile device of a notification device for the hearing impaired according to an embodiment of the present invention. A notification device for a hearing impaired person will be described as follows.

1, a notification device for a hearing impaired person according to an embodiment of the present invention includes a sound sensing unit 10, a storage unit 20, a control unit 30, an output unit 40, and a communication unit 50 ). The output unit 40 includes a vibrating unit 41, a light emitting unit 43, and a display unit 45.

The sound sensing unit 10 includes a microphone (not shown) to receive and sense an external sound. The sound sensing unit 10 senses an external sound, generates a sound signal (sensing signal), and transmits the sound signal to the controller 30.

The storage unit 20 stores in advance a frequency waveform corresponding to a detection sound to be informed to a user of an external sound. At this time, the sensing sound refers to the external sound sensed by the sound sensing unit 10.

In addition, the storage unit 20 may store a rating according to the severity of the emergency situation according to the type of the detected sound.

That is, a sound sample may be stored in advance, and the sound sample may include all types of sensing sounds required by the user. The control unit 30 compares the sound signal input from the sound sensing unit 10 with a sound sample To determine a notification signal.

In addition, the sound sample includes a class according to the degree of emergency according to the type of the detected sound, so that the notification signal according to the class can be determined. At this time, if the controller 30 wants to inform the user of the detected sound by vibration or illumination, it may be difficult for the user to identify the detected sound if the vibration and the illumination are set differently for every detected sound. Therefore, it is desirable to divide the class according to the degree of the emergency situation according to the type of the detected sound so as to be identifiable.

Meanwhile, the sound samples may be stored at the time of manufacture, or may be recorded by a user through a microphone (not shown).

For example, a frequency waveform of each sound, such as a buzzer sound generated when a buzzer is pressed, a fire alarm sound when a fire occurs, a telephone ring sounded by a telephone, a car horn sound generated by a car, And may also include a sound for a situation necessary for the user.

At this time, the grade can be classified according to the degree of emergency. For example, if the grade is set to 3 grade, it is set to 1 grade in case of an emergency such as a fire alarm sound. In case of a situation such as a car horn, it is set to 2 grade. In case of daily life such as a child crying, If it is possible, it can be set to grade 3.

The control unit 30 analyzes the sound signal input from the sound sensing unit 10, converts the sound signal into a corresponding notification signal, and outputs the sound signal to the output unit 40 so that the user can recognize a sound It is possible to judge whether or not the situation exists.

In detail, the control unit 30 receives a sound signal from the sound sensing unit 10 and compares the sound signal with the sound sample stored in the storage unit 20, and when the sound signal inputted as the comparison result matches the specific sound sample, And transmits a notification signal corresponding to the sample to the output unit 40. At this time, the criterion for judging whether or not the sound signal matches with the sound sample may be based on the characteristic of the specific sound such as the natural frequency characteristic irrespective of the sound size.

That is, when the sound signal matches the specific sound sample, the control unit 30 transmits a notification signal for controlling the vibration unit 41, the light emitting unit 43, and the display unit 45 to identify the detected sound . At this time, the control unit 30 outputs a different notification signal to the output unit 40 according to the class of the sound samples stored in the storage unit 20. Particularly, it is possible to transmit a notification signal according to the rating to the vibration unit 41 and the light emitting unit 43.

The control unit 30 can transmit a notification signal to the vibration unit 41 so that the user can tactually recognize the sound and send a notification signal to the light emitting unit 43 and the display unit 45 so as to visually recognize the sound .

For example, when a fire occurs and a fire alarm sounds, the sound sensing unit 10 receives a fire alarm sound, generates a sound signal for the fire alarm sound, and transmits the sound signal to the control unit 30. The control unit 30 compares the frequency waveform of the fire alarm sound stored in advance in the storage unit 20 with the frequency waveform of the fire alarm sound input from the sound detection unit 10. [ If it is determined that the comparison results match, the control unit 30 not only outputs the notification signal corresponding to the first grade, which is the grade of the fire alarm sound, but also outputs a notification signal indicating the fire through the display unit 45 Can be output.

Thus, the user can recognize that a fire has occurred through vibration, illumination, pictures and characters, and evacuate.

The output unit 40 outputs notification information using at least one of vibration, text, picture, and illumination in accordance with a notification signal transmitted from the control unit 30. [ The output unit 40 includes a vibration unit 41, a light emitting unit 43, and a display unit 45. The output unit 40 vibrates through the vibration unit 41 so that the user can tactilely sense the sensed sound And can display lights, pictures, characters, and the like through the light emitting unit 43 and the display unit 45 so that they can be visually perceived.

The vibrating unit 41 is not limited to a motor-type vibrating unit, but various types of vibrating units having vibrations of a strength that the user can feel are all available.

Under the control of the control unit 30, the vibration unit 41 generates vibration by varying the intensity and time of vibration according to the class of the sound samples stored in the storage unit 20.

For example, when a fire is generated and a fire warning sound is input, the vibration unit 41 can generate vibration with the strongest intensity for 8 seconds under the control of the control unit 30. In addition, when the horn sound of the vehicle is input, the vibration unit 41 can generate the standard intensity vibration for 5 seconds, and when the doorbell sound is input, the standard vibration can be generated for 3 seconds.

Therefore, when the user can not visually confirm (such as sleeping), it is effective because vibration can be used to inform the detection sound. That is, when the hearing-impaired person is faced with an emergency, the user can perceive the detected sound quickly by only the vibration without looking at the light-emitting portion 43 and the display portion 45 which are visually confirmed.

Under the control of the control unit 30, the light emitting unit 43 emits light by changing the color of the light and the light emitting time according to the class of the sound samples stored in the storage unit 20. [ At this time, the light emitting unit 43 may typically include a light emitting diode (LED) device, but the present invention is not limited thereto.

For example, the light emitting unit 43 includes LEDs of red, yellow, and blue, and emits light of a predetermined color required according to a notification signal. When a fire occurs and a fire alarm sound is input, A yellow light can be emitted when a buzzer sound is input, and a blue light can be emitted when a buzzer sound is input.

Therefore, the user can recognize the type of the detection sound by simply checking the color with the naked eye. The light emitting unit 43 may be output simultaneously with the vibration unit 41 and the display unit 45 under the control of the control unit 30. [

Under the control of the control unit 30, the display unit 45 can display different phrases, pictures, and the like depending on the type of the sound samples stored in the storage unit 20. [ At this time, the display unit 45 may typically include an LCD (Liquid Crystal Display) device, but the present invention is not limited thereto.

For example, when a fire is generated and a fire alarm sound is input, the display unit 45 may display a phrase "fire alarm" and a "fire" When a beep sound is input, the display unit 45 can display a phrase "car horn" and a picture "car" Species "shape can be displayed.

Therefore, by displaying characters or pictures set on the display unit 45 in accordance with the type of the detection sound corresponding to the sound sample, the detection sound can be notified as a character so that the detection sound can be recognized more accurately than vibration or illumination.

The communication unit 50 receives the notification signal of the control unit 30 and transmits a character string corresponding to the type of the sound sample stored in the storage unit 20 to the predetermined portable terminal. Generally, the predetermined portable terminal may be a smart phone used by a user (a hearing impaired person), or may be a smart phone of a guardian, but the present invention is not limited thereto.

Here, the communication unit 50 can communicate with the portable terminal based on the short-range wireless communication or the long-distance wireless communication. In the present embodiment, it is preferable to use short-range wireless communication such as Bluetooth.

At this time, Bluetooth, Zigbee, Near Field Communication (NFC), or the like can be used for short-range wireless communication. Wireless LAN, Long Term Evolution (LTE), or the like may be used to transmit characters to a mobile terminal based on long distance wireless communication. Of course, the present invention is not limited to the above-mentioned short-distance and long-distance wireless communication, and other wireless communication methods may be adopted.

Meanwhile, the communication unit 50 further includes a Global Positioning System (GPS) module, and when transmitting a character to a protector's mobile terminal, the communication unit 50 may transmit not only the character string but also the position.

For example, as shown in FIG. 3, when a fire occurs and a fire alarm sound is input, the communication unit 50 displays a message "ooo is exposed to fire" under the control of the control unit 30, (Hearing-impaired) can be transmitted together with the character.

In addition, when a horn sound of a vehicle is inputted, a string of "a horn sound is detected" is transmitted according to the user's need, and when a doorbell sound is input, a string of "a doorbell sound is detected" .

On the other hand, when the character is transmitted to the portable terminal of the user (the hearing impaired), the phrase and the picture displayed on the display unit 45 may be outputted in the same manner or may be displayed in more detail.

The notification device is preferably configured in the form of a general personal communication device such as a wristwatch, a necklace, a belt, a rubber band, or the like so that the user (the hearing-impaired person) can carry it. .

FIG. 2 is a view for explaining a control method of a notification device for a hearing impaired person according to an embodiment of the present invention, and a control method of the notification device for a hearing impaired person will be described with reference to FIG.

2, in step S100, the sound sensing unit 10 receives an external sound and generates a sound signal in step S100. That is, the sound sensing unit 10 includes a microphone (not shown) to receive an external sound.

Next, the control unit 30 receives a sound signal from the sound sensing unit 10 (S200).

Next, the control unit 30 compares the sound signal inputted in the step S200 with the sound sample stored in the storage unit 20 in advance (S300). At this time, the criterion for judging whether or not the sound signal matches with the sound sample may be based on the characteristic of the specific sound such as the natural frequency characteristic irrespective of the sound size.

Here, the sound samples may include all types of sound sensed by the user, and the control unit 30 may compare the sound signals input from the sound sensing unit 10 with sound samples to determine the notification signal. In addition, the sound sample includes a class according to the degree of emergency according to the type of the detected sound, so that the notification signal according to the class can be determined.

At this time, it is desirable to divide the class according to the degree of the emergency situation according to the type of the detection sound so as to be identifiable.

On the other hand, grades can be classified according to the degree of emergency of the situation. For example, if the grade is set to 3 grade, it is set to 1 grade in case of an emergency such as a fire alarm sound. In case of a situation such as a car horn, it is set to 2 grade. In case of everyday life If it is possible, it can be set to grade 3.

As a result of the comparison in step S300, if the sound signal matches the specific sound sample, the control unit 30 outputs a notification signal corresponding to the sound sample through the output unit 40 (S400). On the other hand, if the sound signal and the specific sound sample do not match, the process ends.

At this time, the output unit 40 includes a vibration unit 41, a light emitting unit 43, and a display unit 45 to inform the vibration unit 41 that the user (the hearing impaired person) A notification signal can be transmitted to the light emitting unit 43 and the display unit 45 so that the signal can be visually recognized. Thus, the user can perceive the detected sound through vibration, lighting, pictures, characters, and the like.

As described above, the notification device for the hearing-impaired person according to the present embodiment notifies the type of the detected sound through the identification medium for the hearing impaired so that the hearing-impaired person can recognize the detected sound, Make it easy to cope.

In addition, the notification device for a hearing impaired person according to the present embodiment can be miniaturized and carried, so that a person with a hearing impairment can easily recognize the type of a sound regardless of the location where the hearing impaired person is located.

In addition, the notification device for a hearing impaired person according to the present embodiment can improve the user's satisfaction by allowing the user to directly input sound generated mainly in the real life, So that the user can not only know the detected sound correctly but also notify the guardian.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it will be understood by those of ordinary skill in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims. I will understand.
