Systems and methods for providing audio through or near a headrest are provided. The headrest includes an adjustable surface positioned proximate the head of the occupant in use and an acoustic opening configured to emit acoustic energy from the acoustic transducer within a range of directions expected to be occupied by the ears of the occupant. The position of the adjustable surface gives some indication of the position of the occupant's ear, and various audio signal (driver signal) characteristics may be adjusted based on the position of the adjustable surface.
本发明提供了穿过或靠近头枕提供音频的系统和方法。头枕包括可调节表面和声学开口,该可调节表面被定位成在使用时靠近乘坐者的头部,该声学开口被配置为在乘坐者的耳朵预期占据的方向范围内从声换能器发射声能。可调节表面的位置给出乘坐者耳朵的位置的一些指示,并且可以基于可调节表面的位置来调节各种音频信号(驱动器信号)特性。
