陶瓷白耳機，把內部層次拆清楚

A single unbranded wireless earbud shown in a clean exploded 3D product visualization, ceramic-white outer shell above a small driver, circular magnet, compact circuit board and battery, components aligned on one diagonal assembly axis. Pale blue studio background, soft shadows, physically plausible material distinctions, no text or logos, illustrative concept not a manufacturing drawing. Original generic design, no real brand or fabricated specifications.

單隻無品牌無線耳機的乾淨3D分解產品圖，陶瓷白外殼、微型發聲單元、圓形磁體、小電路板與電池沿同一對角裝配軸分層排列。淺藍棚景、柔影，材料區分可信，無文字品牌，僅概念示意而非製造圖紙。 原創通用設計，不虛構真實品牌引數。
