海外询盘常混用 haptic transducer、tactile transducer、bass shaker、LF vibrator。本质多为低频体感执行器，差异在功率、行程、安装与配套功放。正盛可 OEM。
Overseas RFQs often mix “haptic transducer”, “tactile transducer”, “bass shaker” and “LF vibrator”. Most are low-frequency haptic actuators; differences are power, excursion, mounting and amp pairing. Zhengsheng supports OEM.
Bass shaker：影音爱好者常用词，强调「跟着低音晃」。Haptic / tactile transducer：偏工业与家具 OEM 用语，强调可复现的体感反馈。LF vibrator：正盛产品线常用名，强调低频机械输出。采购时建议同时给出功率、阻抗、安装孔距与驱动电压。
额定/最大功率、阻抗（如 4–16Ω 可选）、外形与固定方式、散热壳体、是否需要扩振板、通道数、认证与寿命测试。欢迎索取样机对比 ZS0808、ZS2008-06、ZS2508。
宁波正盛音响科技有限公司成立于 2009 年，专注低频振动器与体感系统，服务国内外智能家具整机客户，可配套功放、扬声器与线束，缩短供应链。
Bass shaker: hobby AV term for “feel the bass”. Haptic/tactile transducer: OEM language for repeatable feedback. LF vibrator: Zhengsheng’s catalog term for low-frequency mechanical output. Always specify power, impedance, bolt pattern and drive voltage.
Rated/max power, impedance (e.g. 4–16Ω selectable), envelope & mounting, heatsink housing, expansion panel need, channel count, reliability tests. Ask for samples of ZS0808, ZS2008-06, ZS2508.
Ningbo Zhengsheng Audio Technology Co., Ltd. (founded 2009) focuses on LF vibrators and haptic systems for global smart-furniture OEMs, with matched amps, speakers and harnesses to shorten the supply chain.
