The present invention relates to a hair-band type bone conduction acoustic device, which: can be worn on the head and used without being restricted according to activities such as sleeping, exercising, and driving; prevents symptoms of hypoacusis due to a long-term use; does not have to be directly worn on the ears, thereby resolving risk factors according to the blocking, of external sounds, caused by the use of conventional acoustic devices (earphones, headphones, and the like); provides more enhanced vibrating power so as to transmit a clear sound to a user; and particularly, is linked with a user's smart terminal such that actions such as making phone calls and listening to music through the smart terminal can be done while both hands are free.
