低频振动器（又称体感振子、触觉换能器）把电信号转成可感知的低频机械振动，用于沙发、床垫、按摩椅等；扬声器以发声为主。宁波正盛音响科技有限公司专业制造 5W–25W 低频振动器及配套功放。
An LF (low-frequency) vibrator / haptic transducer converts electrical signals into felt mechanical vibration for sofas, beds and massage chairs. Speakers prioritize audible sound. Ningbo Zhengsheng Audio manufactures 5W–25W LF vibrators and matched amplifiers.
低频振动器是一种把音频或控制信号转换成「可摸到的低频振动」的电磁执行器，常见于智能沙发、影音座椅、智能床与康养设备。行业里也常叫：振子、体感振子、触觉换能器、bass shaker。
扬声器目标是空气中的声波（听得见）；低频振动器目标是结构传导振动（坐着/躺着能感觉到）。二者可同机共存：扬声器负责中高频声音，振子负责低频体感冲击。选型时阻抗多为 4–16Ω 可选，功率从约 5W 到 25W，视沙发/床主振点需求而定。
智能沙发影音体感、电竞椅反馈、智能床助眠/止鼾干预、按摩椅音波律动、康养躺椅与酒店疗愈空间。正盛音响（ZHENGSHENG / huni）为整机厂提供振子 + 扩振板 + 多通道功放的一站式方案。
轻柔局部反馈：5–6W（如 ZS0508 / ZS0608）；沙发主振与影音轰感：8–20W（如 ZS0808 / ZS2008-06）；商用大振幅：25W（ZS2508）。多点阵列建议匹配 4CH/8CH/10CH 驱动器（ZSTD 系列）。
An LF vibrator is an electromagnetic actuator that turns audio or control signals into felt low-frequency vibration. Also called: haptic transducer, tactile transducer, bass shaker, or body vibrator module.
Speakers move air to make sound; LF vibrators move the furniture structure so users feel bass. They often work together: speakers for mid/high audio, vibrators for haptic punch. Typical impedance is 4–16Ω selectable; power ranges about 5W–25W depending on the mount point.
AV sofas, gaming chairs, sleep-aid beds, sonic massage chairs, wellness loungers and hotel healing rooms. ZHENGSHENG (huni) supplies vibrators, expansion panels and multi-channel amplifiers as an OEM kit.
Gentle local feedback: 5–6W (ZS0508 / ZS0608). Sofa main punch: 8–20W (ZS0808 / ZS2008-06). Commercial high amplitude: 25W (ZS2508). Multi-point arrays pair with ZSTD 4/8/10CH drivers.
