The invention discloses an automobile active sound wave device, which is characterized in that in the automobile travel process, an active sound wave controller acquires automobile state signals suchas automobile engine or motor rotating speed, torque, automobile speed, accelerator opening, gears and the like through using a finished automobile CAN signal; and a loudspeaker is used for giving outpre-designed same-amplitude reverse sounds to counteract noise of an engine or a motor in a cockpit, and the acceleration sound quality of the whole automobile is improved. The automobile active sound wave device is compact in structure and small in occupied space, and a vehicle-mounted vehicle machine, a vehicle-mounted power amplifier and a vehicle-mounted loudspeaker can be utilized; the required pure engine surging sound waves with brand features are emitted through the loudspeaker, the sound properties of the engine or the motor is improved, the driving pleasure is improved, and the auditory comfortable feeling is brought to a user; and by means of the active sound wave controller, engine noise of various styles and types can be stored in advance, a user can switch sound styles randomly, and the modern sense and the science and technology sense of the whole vehicle are improved.
本发明揭示了一种汽车主动声浪装置,在汽车行程过程中,主动声浪控制器通过整车CAN信号获取汽车发动机或电机转速、扭矩、车速、油门开度、档位等车辆状态信号,使用扬声器发出预先设计好的同幅反相的反声音实现对驾驶舱内发动机或电机噪声的抵消,提升了整车的加速声品质;本发明结构紧凑,占用空间小,可以利用车载车机、车载功放及车载扬声器;本发明通过扬声器还发出所需要的具有品牌特色的纯洁的发动机澎湃声浪,改善发动机或电机声音的特性,提升驾驶乐趣,给用户带来听觉上的舒适感受;本发明通过主动声浪控制器,可以预先存储多种风格类型的发动机噪声,用户可任意切换声音风格,提升整车现代感和科技感。
