The invention discloses an intelligent cockpit domain sound field multi-sound-area control method and device, the interior of an intelligent cockpit is divided into a plurality of sound areas, each sound area corresponds to at least one sound area loudspeaker, and the method comprises the following steps: in an independent sound field mode, when the sound area loudspeaker corresponding to one sound area provides sound field service according to first sound source information, the sound area loudspeaker corresponding to the sound area provides sound field service according to the first sound source information; the sound area is called as a current sound area, second sound source information opposite to the first sound source information in waveform is obtained, and at least one sound area loudspeaker corresponding to at least one other sound area except the current sound area provides synchronous silencing service according to the second sound source information. Compared with the prior art, when one sound area provides sound field service, the other sound areas play the reverse sound source opposite to the waveform of the sound source of the previous sound area, so that the sound source interference of the previous sound area on the other sound area is prevented, the calculation is simple, the effect is good, and the experience is good.
本发明公开了一种智能座舱域音场多音区控制方法及装置,智能座舱内部划分为若干个音区,每一音区对应至少一个音区扬声器,所述方法包括:在独立音场模式下,一所述音区对应的音区扬声器依据第一音源信息以提供音场服务时,将该音区称为当前音区,获取与所述第一音源信息波形相反的第二音源信息,除当前音区外的其他至少一音区对应的至少一个所述音区扬声器依据第二音源信息提供同步的消音服务。与现有技术相比,本发明在一音区提供音场服务时,其他音区播放与前一音区的音源的波形相反的反向音源,以防止前一音区对另一音区的音源干扰,计算简单,效果好,体验佳。
