智能床体感方案常用低频振动同步音乐或处方波形，辅助放松、助眠与轻按摩；需控制振幅与分区，避免影响睡眠连续性。正盛提供睡床体感方案与匹配振子。
Smart beds use LF vibration synced to music or waveforms for relaxation, sleep aid and light massage—amplitude and zoning matter. Zhengsheng supplies bed haptic solutions and matched vibrators.
腰背主振、腿部辅振；功率偏中小（5–18W）更易长时间舒适运行。可配合扩振板扩大床垫传导。
沙发偏「影音冲击」；睡床偏「节律放松」。睡床更强调低噪音、低发热与可调弱档。
