Description

피지티를 이용하여 골도청각을 자극할 수 있는 보청기{The Device for Dumb Person, using PZT}Hearing aid that can stimulate bone conduction hearing using Fijiti {The Device for Dumb Person, using PZT}

일반적으로 선천적 또는 후천적 이유로 인하여 고막의 기능이 비정상적인 경우 소리를 전혀 듣지 못하거나 난청으로 어려움을 격게 된다.In general, if the function of the eardrum is abnormal due to congenital or acquired reasons, it is difficult to hear sound or suffer from hearing loss.

어느 정도의 난청은 소위 보청기를 착용하여 해결할 수 있지만, 난청이 심각한 상태에 대해서 그다지 도움이 될 수 없는 것 또한 사실이다.Some degree of hearing loss can be solved by wearing so-called hearing aids, but it is also true that hearing loss is not very helpful for serious conditions.

현재 상용의 보청기는 (콘덴서) 마이크에 입력되는 시그널을 적절히 증폭하여 마그네틱 이어폰에 출력하는 방식으로 이루어져 있다.Currently, commercial hearing aids consist of amplifying the signal input to the (condenser) microphone and outputting it to the magnetic earphone.

한편 외이와 중이에 손상을 입었어도 골도청각, 즉 귓바퀴 주위의 뼈가 진동하는 경우 소리를 들을 수 있는 의학적 원리에 착안하여, 노인성 난청에 따른 전화 통화의 불편함을 해소할 수 있는 골도전화기가 개발되어 있다.On the other hand, we have developed a bone conduction phone that can resolve the discomfort of phone calls caused by senile hearing loss by focusing on the medical principles that can be heard even when the external ear and middle ear are damaged. It is.

그러나 상기 골도전화기의 핵심이 되는 골도진동자의 구조는 다름아닌 마그네틱 이어폰과 유사한데, 전기신호를 가동코일에 가하여 발생하는 마그네트와의 반발력을 이용하여 기계적 진동을 발생시키고 있기 때문이다.However, the structure of the bone conduction oscillator, which is the core of the bone conduction phone, is similar to the magnetic earphone, because it generates mechanical vibration by using the repulsive force with the magnet generated by applying an electric signal to the movable coil.

본 고안은 보청기에 적용할 경우 상기 골도진동자의 원리 및 구조로 인하여야기될 수 있는 디자인 및 기구적 난점을 원천적으로 해결하기 위하여, 상기 골도진동자를 이용하지 않는 보청기에 관한 것이다.The present invention relates to a hearing aid that does not use the bone conduction vibrator in order to fundamentally solve the design and mechanical difficulties that can be caused by the principle and structure of the bone conduction vibrator when applied to the hearing aid.

구체적으로 본 고안은 디자인 및 기구적 난점을 개선할 수 있도록 하기 위하여, 전기신호를 기계적 진동으로 변환할 수 있는 PZT의 소형박막구조에 주목하고,이에 따라 기존의 골도진동자가 아닌 PZT를 이용하여 골도청각을 자극할 수 있는 보청기에 관한 것이다.Specifically, in order to improve the design and mechanical difficulties, the present invention pays attention to the small thin film structure of the PZT that can convert the electrical signal into mechanical vibration, and accordingly the bone conduction using PZT rather than the existing bone conduction vibrator Hearing aids that can stimulate hearing.

도 1은 본 고안에 따른 PZT를 이용하여 골도청각을 자극할 수 있는 보청기의블록도.1 is a block diagram of a hearing aid capable of stimulating bone hearing using PZT according to the present invention.

본 고안을 첨부된 도면에 의하여 상세히 설명하면 다음과 같다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

마이크(1)에 입력되는 소리는 전기신호로 변환되는데, 이때의 미약한 전기신호를 증폭하기 위한 증폭단(2)가 존재한다.The sound input to the microphone 1 is converted into an electric signal, and there is an amplifying stage 2 for amplifying the weak electric signal at this time.

한편 상기 증폭단(2)의 입력이 너무 커서 출력이 포화되어 왜곡되는 일이 없도록 자동으로 이득을 조절할 수 있는 AGC단(3)이 상기 증폭단(2)의 입출력에 연결되어 있다.On the other hand, the AGC stage 3 which can automatically adjust the gain so that the input of the amplifying stage 2 is so large that the output is not saturated and distorted is connected to the input / output of the amplifying stage 2.

물론 상기 증폭단(2)의 출력에 포함된 노이즈를 제거하지 않으면 안되는 바,상기 증폭단(2)의 출력에는 필터단(4)가 연결되어 있다.Of course, the noise included in the output of the amplifier stage 2 must be removed, and the filter stage 4 is connected to the output of the amplifier stage 2.

더욱 라디오, 핸디폰 등의 출력을 연결할 수 있는 외부 라인짹(5)와 상기 필터단(4)에는 필요에 따른 선택이 가능하도록 라인 절환부(6)이 연결되어 있다.In addition, an external line tweeter 5 capable of connecting an output of a radio, a portable phone, etc., and a line switching unit 6 are connected to the filter stage 4 to enable selection as necessary.

특히 핸디폰의 경우 상기 마이크(1)을 이용하여 통화할 수 있도록 상기 마이크(1)이 상기 외부 라인짹(5)에 연결되어 있다.In particular, in the case of a mobile phone, the microphone 1 is connected to the external line tweeter 5 so that the call can be made using the microphone 1.

전기신호를 기계적 진동으로 변환시키는 PZT(8)는 임피던스 매칭을 위해 상기 라인 절환부(6)에 연결된 PZT 드라이버(7)에 의해 구동된다.The PZT 8, which converts an electrical signal into mechanical vibrations, is driven by a PZT driver 7 connected to the line switch 6 for impedance matching.

본 고안에 의하면 기계적 구조를 갖는 기존의 골도진동자를 이용하지 않으면서 골도청각에 대한 자극이 가능하게 되는 동일한 효과를 얻을 수 있다.According to the present invention, it is possible to obtain the same effect that the stimulation for bone hearing can be achieved without using the existing bone conduction vibrator having a mechanical structure.

물론 본 고안은 난청에 불구하고 라디오, 핸드폰 등을 보다 편리하게 이용할수 있도록 한다.Of course, the present invention allows for more convenient use of radios, mobile phones, etc. despite hearing loss.
