Abstract
본 고안은 자동차용 소음기에 관한 것으로서, 기존의 일반적인 자동차용 소음기는 연소가스가 배기되는데 저항이 있으므로 연료의 낭비를 초래하였다. 이에 본 발명은 상기 저항을 없애는데 그 목적이 있다.The present invention relates to a vehicle silencer, the conventional general silencer for automobile caused a waste of fuel because the resistance to the exhaust gas is exhausted. Accordingly, the present invention has the object to eliminate the resistance.
이런 목적을 달성하기 위하여 본 고안은 배기파이프상에 마이크와 스피커를 설치하고 마이크를 통해 들어온 엔진의 배기소음과 반대 싸이클의 소리를 전자적으로 합성하여 배기파이프상에 설치한 스피커를 통해 배기소음과 만나게 구성한다.In order to achieve this purpose, the present invention installs a microphone and a speaker on the exhaust pipe, and electronically synthesizes the exhaust noise of the engine and the opposite cycle of the engine through the microphone to meet the exhaust noise through the speaker installed on the exhaust pipe. Configure.
상기 구성에 의해 배기가스가 저항없이 배출됨으로써 소음기로 인한 엔진출력의 저하를 막고 소음 또한 없애게 되는 것이다.By the above configuration, the exhaust gas is discharged without resistance, thereby preventing a decrease in engine output due to a silencer and removing noise.
Description
본 고안은 자동차용 소음기에 관한 것이다.The present invention relates to a silencer for automobiles.
일반적으로 자동차용 소음기는 배기가스 압력의 맥동현상을 없애기 위해 배기가스에 저항을 주어 지체시킴으로써 종단에서 배출되는 배기가스의 압력을 일정하게 하였으므로 소음은 줄였으나 저항으로 인한 엔진출력의 저하를 초래하였다.In general, automotive silencers reduce the engine pressure due to resistance, although noise is reduced because the pressure of the exhaust gas discharged from the terminal is made constant by resisting and delaying the exhaust gas to eliminate pulsation of the exhaust gas pressure.
이에 본 고안은 상기의 문제를 해결하기 위해 배기가스가 저항없이 배출되게하고 소음은 반대 싸이클의 소리를 합성하여 음파를 상쇄함으로써 엔진출력의 저하없이 소음을 없애는데 그 목적이 있다.Accordingly, the present invention has the purpose of eliminating the noise without deterioration of the engine output by canceling the sound waves by synthesizing the sound of the opposite cycle to the exhaust gas discharged without resistance to solve the above problems.

1: 엔진 2: 배기파이프1: engine 2: exhaust pipe
3: 반대 싸이클 소리 합성기 4: 마이크3: reverse cycle sound synthesizer 4: microphone
5: 스피커5: speaker
상기의 목적을 달성하기 위하여 본 고안에 따른 소음기의 구조는 배기파이프(2)상의 엔진(1)측에 마이크(4)를 설치하고 종단측에 스피커(5)를 설치하여 마이크(4)를 통해 들어온 소리를 소리 합성기(3)에서 반대 싸이클의 소리를 합성하여 스피커(5)를 통해 원래의 배기소음과 만나게 함으로써 소음을 상쇄시킨다.In order to achieve the above object, the structure of the silencer according to the present invention is to install the microphone 4 on the engine 1 side on the exhaust pipe 2 and the speaker 5 on the end side through the microphone 4. The sound is canceled by combining the sound of the opposite cycle in the sound synthesizer 3 with the original exhaust noise through the speaker 5.
상기한 바와 같이 원래의 배기소음과 반대 싸이클의 소리가 만나 음파가 상쇄됨으로써 소음이 없어지고 배기가스가 저항없이 배출됨으로써 엔진출력의 저하현상을 없애는 효과를 제공한다.As described above, the sound of the opposite cycle meets the original exhaust noise and the sound wave is canceled, and the exhaust gas is discharged without resistance, thereby providing an effect of eliminating the degradation of the engine output.
