一体式柱状扩声扬声器

带蓝牙功能的8英寸有源便携式PA音箱 **Explanation of changes:** 1. **扬声器 → 音箱**: In professional B2B audio equipment contexts, "音箱" (cabinet/loudspeaker system) is the more established standard term for a complete powered portable PA unit, whereas "扬声器" (speaker driver) typically refers to individual transducers. Since this is a complete self-contained unit, "音箱" is more precise and professional. 2. **Sentence structure remains natural** and follows proper Chinese technical terminology conventions for audio equipment specifications. All other elements (蓝牙、有源、便携式、PA) are correct and appropriately formal for B2B professional copy.

15英寸有源低音炮 **Explanation of change:** - "超低音音箱" (ultra-low frequency speaker cabinet) is technically correct but slightly verbose for a product name/UI label. - "低音炮" (powered subwoofer) is the established, concise professional term in Chinese audio terminology and matches the brevity of the English source. - The translation maintains formal written Chinese and preserves all technical accuracy while improving naturalness and register alignment for B2B professional copy.

双向音频扩声扬声器系统 **Reasoning:** - "Two-Way" → "双向" ✓ (correct) - "Sound Reinforcement" → "扩声" is adequate, but "音频扩声" is more precise and professional in B2B audio contexts - "Loudspeaker System" → "扬声器系统" ✓ (correct) The improved version uses "音频扩声" (audio sound reinforcement) instead of just "声音扩声" to better reflect professional audio terminology and avoid the slight redundancy in the original ("声音" + "扬声器" creates some semantic overlap). This aligns with formal B2B audio trade language in Simplified Chinese.

18英寸电源供电可吊挂超低音音箱 **Explanation of improvements:** 1. **"电动"** → **"电源供电"**: "电动" (electric/motorized) is imprecise. "电源供电" (powered/mains-powered) is the correct B2B audio terminology for active/powered subwoofers. 2. **"可飞行"** → **"可吊挂"**: "可飞行" (flyable/can fly) is colloquial and imprecise. In professional audio/AV systems, "可吊挂" (rigging-capable/flown) is the established term for equipment that can be suspended from rigging systems. 3. **"低音炮"** → **"超低音音箱"**: While "低音炮" is colloquial/casual Chinese, "超低音音箱" (subwoofer cabinet) is the formal B2B professional terminology. This maintains register consistency with formal written Chinese (书面语). 4. **Overall structure**: More precise
