The invention discloses a loudspeaker control method, a loudspeaker control system and a vehicle body domain controller, which are used for realizing adjustment of sound transmission directions of loudspeakers with fixed positions and angles so as to meet different requirements of different elevations for sound fields. The method comprises the steps: when a trigger event of playing media sound is detected, acquiring parameter information of a preset position, the preset position comprising a vehicle cabin seat; determining the ear position of the person at the preset position according to the parameter information of the preset position; adjusting the angle of an overturning structure in the loudspeaker mesh enclosure according to the position of the human ear, and regulating the sound transmission direction of the loudspeaker to correspond to the position of the human ear through the overturning structure, wherein the overturning structure is composed of a plurality of blade structures arranged at intervals. By adopting the scheme provided by the invention, the sound transmission direction can be changed based on the angle of the turnover structure in the loudspeaker mesh enclosure, so that the adjusted sound transmission direction of the loudspeaker corresponds to the position of a human ear.

    本申请公开了一种扬声器的控制方法、系统及车身域控制器,用以实现对固定位置及角度的扬声器的声音传播方向的调节,以满足不同升高用于对于声场的不同需求。所述方法包括:在检测到播放媒体声音的触发事件时,获取预设位置的参数信息,其中,预设位置包括车舱座位;根据预设位置的参数信息确定位于预设位置的人员的人耳位置;根据人耳位置调整扬声器网罩内翻转结构的角度,以通过翻转结构将扬声器的声音传播方向调整为与人耳位置对应,其中,翻转结构由多个间隔排布的叶片结构构成。采用本申请所提供的方案,能够基于扬声器网罩内翻转结构的角度来改变其声音传播方向,使得调整后的扬声器的声音传播方向与人耳位置对应。
