Active noise cancellation apparatus |
摘要 |
Provided is an active noise cancellation apparatus capable of reliably reducing road noise by a technique other than mounting a vibration generator on a floor panel itself or another plate-like interior part itself, while reducing costs and size of the apparatus. A reference signal detector is mounted on a knuckle and the vibration generator is mounted on a wheel housing or a suspension member. An error signal detector detects vibration of the wheel housing or vibration of the suspension member as an error signal, or detects sound in a vehicle interior as an error signal. A controller controls the vibration generator based on the reference signal and the error signal so as to reduce the error signal. |
