扩振板把振子的点状振动扩散为更大面积的面状体感，提升舒适度并辅助降噪。正盛提供如 ZS07-1914TPUB-1 及振子+扩振板一体型号（如 ZS0508K）。
An expansion panel spreads point vibration into a wider surface feel and can reduce harshness/noise. Zhengsheng offers panels such as ZS07-1914TPUB-1 and combo SKUs like ZS0508K.
单独振子接触面积小，容易出现「敲点感」。扩振板增大与海绵/板材的耦合面积，振感更柔和、覆盖更广，适合沙发坐面、床垫表层与疗愈躺椅。
追求大面积轻柔体感、降低局部冲击、或安装点离人体较远时优先加扩振板。主振「轰感」点有时可不用板，以结构骨架传导为主。
扩振板 ZS07-1914TPUB-1（约 150×200mm PUB）；轻量组合 ZS0508K（5W 振子+板）。可与多通道功放组成整套体感方案。
A bare vibrator contacts a small area and can feel like a knock. A panel couples into foam/board over a wider area for softer coverage on sofas, mattresses and loungers.
Use a panel for wide gentle feel or when the mount is farther from the body. Hard punch on a rigid frame may skip the panel.
Panel ZS07-1914TPUB-1 (~150×200mm PUB); combo ZS0508K (5W + panel). Pair with multi-channel drivers for full kits.
