PURPOSE: A vibration ear phone is provided to improve efficiency of a sound by outputting the vibration of a mid-bass band through a cylindrical mid-bass transmission unit while outputting the vibration of a high sound band through a mastoid. CONSTITUTION: A vibration unit(210) includes a cover and a basket combining a face plate, a voice coil, and a magnet, and outputs the sound through the vibration. A mid-bass transmission unit(220) outputs the vibration of the mid-bass through an outer wall of the ear by receiving the vibration unit. A mastoid(230) outputs the vibration of the high pitched sound generated from the face plate through a protrusion. The protrusion is inserted and combined in the hole formed in the center of the face plate of the vibration unit while passing through the mid-bass transmission unit. The mid-bass transmission unit includes a partition(221) divided to an inner side of the cylindrical circumference direction. The mid-bass transmission unit receives the vibration unit in one side of the partition and outputs the sound of the mid-bass band in the outer wall of the ear.
