A voice coil structure for bone conduction and a bone conduction speaker are provided to implement miniaturization and reduce the weight by integrating a vibrator. A bone conduction speaker(1) includes housings(10, 20), a magnet(50), a voice coil structure, and a virator(70). The housing has an inner space. The magnet is positioned in the bottom of the housing. A voice coil structure includes a bobbin(30), a ferrite core(60), and a voice coil(40). A hollow is formed in the center of the bobbin. The voice coil is wound around an outer circumference of the voice coil. The voice coil structure is positioned on the upper side of the magnet. The vibrator includes a first support unit, an upper portion, and a first lower portion. The upper portion faces the inner side of the upper side of the housing. |
