Double-Voice Coil Moving-Coil Loudspeaker

摘要

A double-voice coil moving-coil loudspeaker comprises a bracket. A U-shaped cup with a circular groove is fixed in the bracket. A vibrating diaphragm is fixed on the bracket at the position of the U-shaped cup. A large voice coil and a small voice coil distributed in a concentric circle are arranged on the vibrating diaphragm. A circular large magnet and a circular small magnet distributed in a concentric circle are arranged in the U-shaped cup. A circular big washer and a circular small washer are respectively arranged on an upper surface of the large magnet and the small magnet. The big voice coil and the small voice coil are respectively arranged in a gap formed by the U-shaped cup and the big washer and a small gap formed between the U-shaped cup and the small washer. The U-shaped cup is provided with air vents. The air vents of the U-shaped cup are communicated with a gap between the big washer and the smaller washer and a gap between the big magnet and the small magnet. The invention has the benefit of improving sound quality while reducing the cost of manufacturing.
