The invention discloses a noise reduction device based on a propagation path, a noise reduction method and a vehicle, the noise reduction device based on the propagation path comprises a noise sensor, a vibration generator and an electronic control module, the noise sensor is located between a noise propagation main body and a noise source, and the noise sensor is arranged towards the noise source; the noise sensor is used for detecting sound wave vibration of a noise source; the vibration generator is fixed on the noise transmission main body, and reverse vibration generated by the vibration generator can counteract sound wave vibration on the noise transmission main body; the electronic control module is connected between the noise sensor and the vibration generator so as to convert a vibration signal of the noise transmission body into a control signal and transmit the control signal to the vibration generator. According to the noise reduction device based on the propagation path, the influence of the noise outside the vehicle on the environment in the vehicle can be effectively improved, and then the comfort of the environment in the vehicle is better improved.

    本发明公开了一种基于传播路径的降噪装置、降噪方法和车辆,所述基于传播路径的降噪装置包括:噪声传感器、震动发生器和电子控制模块,噪声传感器位于噪声传播主体和噪声源之间,且噪声传感器朝向噪声源布置,噪声传感器用于检测噪声源的声波振动;震动发生器固定在噪声传播主体上,震动发生器产生的反向振动可以抵消噪声传播主体上的声波振动;电子控制模块连接在噪声传感器和震动发生器之间,以将噪声传播主体的振动信号转换为控制信号并传输至震动发生器。根据本发明的基于传播路径的降噪装置可以有效地改善车外噪声对车内环境的影响,进而更好地提升车内环境的舒适性。
