The invention discloses an audio playing method and system for a vehicle-mounted virtual sound image, and the method comprises the steps: S1, at least one sound region is arranged in a vehicle, and the sound region comprises a directional loudspeaker and a loudspeaker array disposed on a headrest; s2, performing frequency division on the sound source signal, and dividing the sound source signal into a first audio signal higher than a frequency division point and a second audio signal lower than the frequency division point; s3, processing the second audio signal by adopting a virtual sound image algorithm, and playing the processed second audio signal in a virtual sound area except a position behind the listener by a loudspeaker array; the first audio signal is directionally played in the virtual sound area by the directional loudspeaker. According to the method, directional acoustics and a virtual sound image algorithm are combined, and the non-inductive virtual sound image effect in the vehicle and the independent sound area sound effect with the good isolation degree are achieved.
本发明公开了一种车载虚拟声像的音频播放方法及系统,所述方法包括S1,在车内至少设置一个音区,音区包括定向扬声器及设置于头枕上的扬声器阵列;S2,对声源信号进行分频,分为高于分频点的第一音频信号和低于分频点的第二音频信号;S3,对第二音频信号采用虚拟声像算法进行处理,处理后的第二音频信号由扬声器阵列播放于位于除收听者后方位置的虚拟音区;第一音频信号由定向扬声器定向播放于虚拟音区。本发明将定向声学与虚拟声像算法进行结合,实现了车内无感的虚拟声像效果及较好隔离度的独立音区音效。
