  • Publication number: 20170111728
    Abstract: Disclosed are a bone conduction speaker module and bone conduction earphones having the bone conduction speaker modules. More particularly, the present invention relates to a bone conduction speaker module and bone conduction earphones having the bone conduction speaker modules, wherein the bone conduction speaker modules can accurately output sound, can stably output sound with fewer vibrations, enable a wearer to comfortably use the earphones, can prevent strain to the wearer by minimizing influence of magnetic force, can facilitate wearing of the earphones, and can prevent an accident from occurring by allowing the wearer to hear external sounds. To this end, a bone conduction speaker module used in earphones, headphones, and a hearing aid, includes: a housing including a first casing covering a portion coming into contact with a human body and a second casing covering a side of the first casing; a magnet part; and a voice coil part.
