机械机芯靠滚轮/气囊；音波体感靠低频振动器阵列营造律动与放松感，结构更轻、噪音可控，适合与影音或疗愈内容联动。正盛提供按摩椅专用体感方案。
Mechanical chairs use rollers/airbags; sonic haptics use LF vibrator arrays for rhythm and relaxation—lighter structure, controllable noise, easy AV/healing sync. Zhengsheng supplies chair haptic kits.
机械按摩偏「揉捏按压」；音波体感偏「节律振动与穿透感」，可随音乐或处方波形变化，适合减压、影音同步与轻理疗辅助，不替代医疗器械宣称。
肩背/腰臀分区布置多颗振子，扩振板提升舒适面，多通道功放独立调幅。可参考正盛「智能按摩椅方案」与 ZSTG 体感套件。
Mechanical massage emphasizes kneading/pressure; sonic haptics emphasize rhythmic vibration that can follow music or programmed waveforms—for relaxation and AV sync, not as a medical device claim.
Zone vibrators across back and seat, expansion panels for comfort area, multi-channel amps for level control. See Zhengsheng smart massage-chair solution and ZSTG kits.
