声波电动牙刷 (Sonic Electric Toothbrush) (原型参考：附件111.txt 案例十 | 技术扩充：Sora2视频生成关键词.txt) [00-03s] Sonic Tech Visualization: A sleek pink electric toothbrush floats in a dark tech void. It switches on, and the bristles vibrate at high frequency (blurring slightly). We see water droplets placed on the bristles instantly atomizing into a fine mist due to the sonic speed (slow-motion physics capture). Background graphics show "38,000 VPM". [04-08s] Deep Cleaning Action: Cut to a close-up of the brush head moving against a transparent dental model. The camera uses a "macro see-through" view. The vibrating bristles create micro-bubbles in the toothpaste foam, which are shown rushing deep between the teeth gaps, flushing out debris efficiently. [09-12s] Gentle on Gums: A shot of a model brushing her real teeth. She looks relaxed, not grimacing, indicating the brush is gentle. The pressure sensor light on the handle blinks green to show optimal pressure. [13-15s] Shining Result: The model rinses and smiles broadly at the mirror. Her teeth look sparkling clean and white. She places the brush on a wireless charging base. Text: "Sonic Deep Clean | 100% Plaque Removal". Style: Hygienic, bright, scientific but accessible.
