Abstract

PURPOSE: An electronic muffler for automobile is provided to remove a noise without the degradation of engine output by discharging an exhaust gas with no resistance and offsetting a sound wave against a sound of inverse cycle. CONSTITUTION: A mike(4) is set up on an engine(1) side of an exhaust pipe(2). A speaker(5) is set up on an ending side of the exhaust pipe(2). A sound synthesizer(3) synthesizes a sound of a cycle inverse to a sound from the mike(4). An exhaust noise is offset against the sound of inverse cycle through the speaker(5).

Description

자동차용 전자소음기{Electric muffler for automobile}Electric muffler for automobile

본 발명은 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 저하(1)를 초래하였다.In general, automotive silencers reduce the exhaust gas pressure due to resistance by reducing the pressure of exhaust gas discharged from the terminal by delaying the resistance to exhaust gas to eliminate pulsation of exhaust gas pressure. Caused.

이에 본 발명은 상기의 문제를 해결하기 위해 배기가스가 저항없이 배출되게 하고 소음은 반대 싸이클의 소리를 합성하여 음파를 상쇄함으로써 엔진출력의 저하없이 소음을 없애는데 그 목적이 있다.In order to solve the above problem, the present invention has an object of eliminating noise without degrading engine output by allowing exhaust gas to be discharged without resistance and noise canceling sound waves by synthesizing sounds of opposite cycles.

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 발명에 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 provided with a microphone 4 on the engine 1 side on the exhaust pipe 2 and a speaker 5 on the end side of the silencer 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.
