JBL 气动升降扬声器支架

- **Accurate**: Correctly conveys "manual adjust speaker pole" - **Technically appropriate**: Uses established Chinese terms (手动 = manual, 调节 = adjust, 扬声器 = speaker, 立杆 = pole/stand) - **Concise**: Maintains the brevity of the UI label (5 characters vs. 6 English words) - **Formal register**: Suitable for B2B professional product documentation - **Brand integrity**: Preserves "JBL" in original form

PRX425 防护套

PRX418S 的带垫衬防护罩

改进的翻译： PRX415M 带衬垫保护套 **说明：** - 原翻译"保护套"过于简洁，未能准确传达"Padded"（带衬垫）的关键特征 - 改进版"带衬垫保护套"更准确地反映了产品的功能特性（衬垫提供保护） - 保留了产品型号 PRX415M 的准确性

PRX412M 保护罩 **Explanation of change:** - "防护套" (protective cover) is acceptable but slightly informal/generic - "保护罩" (protective cover/shield) is more standard B2B professional terminology for equipment covers in audio contexts - Both preserve the model number PRX412M exactly as required - The change maintains brevity appropriate for a UI label while improving technical register for professional audio equipment documentation
