Description

무전원인가 노이즈 캔슬러가 내장된 젠더 장치Gender device with built-in noise canceller
본 발명은 무전원인가 노이즈 캔슬러가 내장된 젠더 장치에 관한 것으로 더욱 상세하게는, 기존에 사용중인 송수화기에 노이즈 캔슬러가 내장된 젠더를 어댑터 형태로 직렬로 연결함으로써, 송수화기의 구조 변경 및 손상없이 연결이 간단하면서 주변의 소음을 제거해 명확한 음성신호 정보만을 전송하는 기술에 관한 것이다.The present invention relates to a gender device with a built-in noise canceller without power, and more particularly, by connecting a gender with a noise canceller built-in to an existing handset in series in the form of an adapter, without changing the structure of the handset and damaging it. It relates to a technology that transmits only clear voice signal information by removing noise from the surroundings while simple connection.
마이크, 무전기, 휴대폰 등으로 말(음성)을 전하려고 할 때에 주변 소음이 심한 장소에서는 전달하려는 송신자의 음성과 주변 소음이 같이 혼입되어 전달된다.When trying to deliver speech (voice) through microphones, walkie-talkies, mobile phones, etc., the voice of the sender to be transmitted and the surrounding noise are mixed and transmitted in a place with high ambient noise.
이에 따라 수신자측에서는 높은 소음레벨로 인하여 송신자의 음성내용이 불명료하게 전달되어 수신자가 정확한 음성내용을 청취할 수 없는 사례가 빈번하게 발생한다.Accordingly, there are frequent cases in which the receiver's voice content is transmitted indistinctly due to the high noise level and the receiver cannot hear the correct voice content.
특히, 소음이 큰 건설현장, 쿵쾅거리는 소음이 심한 공장, 차량의 왕래가 많은 도로, 소음이 큰 굴삭기와 같은 건설장비, 화물트럭의 이동이 빈번한 건설현장, 소음이 심한 군사장비(탱크, 장갑차, 함정 기관실 등)에서 전달자의 음성을 제대로 전달하기보다는 주변소음에 같이 묻혀 수신자가 못 알아듣는 경우가 많다.In particular, noisy construction sites, factories with heavy thumping noises, roads with a lot of traffic, construction equipment such as excavators with high noise, construction sites with frequent freight trucks, and military equipment with heavy noise (tanks, armored vehicles, Rather than properly transmitting the voice of the sender in the ship's engine room, etc.), it is often buried in ambient noise that the receiver cannot understand.
따라서, 송신측에서는 주변의 소음이 혼입되는 과정에서 잡음만을 제거하여 깨끗한 음성정보만을 전달하는 수단이 필요하고, 수신측에서도 소음이 같이 혼입된 음성정보를 소음만을 제거함으로써 깨끗한 음성정보만 들을 수 있는 수단을 강구할 수 있으면 좋을 것이다.Therefore, the transmitting side needs a means to transmit only clean voice information by removing only the noise in the process of mixing the surrounding noise, and the receiving side also has a means to hear only clean voice information by removing only the noise. It would be nice if I could find it.
소음제거의 일반적인 전자적 방법으로는 1) 소음신호와 반대되는 위상의 신호를 발생시켜서 원 소음을 상쇄시키는 방법, 2) 소음 레벨을 전체적으로 낮추는 방법 등이 있겠으나, 주변의 모든 소음을 완전히 주변 소음을 제거하기는 어렵다.Common electronic methods of noise reduction include 1) a method of canceling the original noise by generating a signal of a phase opposite to the noise signal, and 2) a method of lowering the noise level as a whole, but all the surrounding noise is completely eliminated. It is difficult to remove.
시중에 다양한 노이즈 캔슬링 기능이 탑재된 마이크나 이어폰이 판매되고 있지만, 이는 디지털적으로 음성을 가공하기 때문에 음질이 왜곡되어 음성 인식율이 전체적으로 저하되는 문제점이 있고, 외부전원이 필히 인가되어야만 작동하는 전자IC칩 형태로 구성되는 단점이 있다.On the market, microphones or earphones with various noise canceling functions are on the market, but since they are digitally processed, the sound quality is distorted and the overall voice recognition rate is degraded, and an electronic IC that operates only when external power is applied. There is a disadvantage of being configured in a chip form.
