Abstract

A vibration motor, comprising a base portion which expands perpendicular to a vertical center axis, a magnet portion which is securely mounted on an upper side of the base portion in a vertical direction, a vibrator portion which is disposed around the magnet portion and vibrates vertically, a cover portion which is fixed to the base portion and covers upper and side portions of the magnet portion and the vibrator portion, an elastic member which is disposed between an upper inner surface of the cover portion and a top portion of the vibrator portion, and a circuit board which is flexible and coupled to a top surface of the base portion and a bottom portion of the vibrator portion, wherein the vibrator portion includes a coil portion which faces the magnet portion in a circumferential direction, and a mass portion which is fixed to the coil portion, the base portion includes a base protrusion which protrudes from the cover portion to a radially outer side, and the circuit board includes a lower terminal portion which protrudes outward from between the cover portion and the base portion in a radial direction and is fixed to a top surface of the base protrusion, an upper terminal portion which is fixed to the lower portion of the vibrator portion and electrically connected to the coil portion, and two leg portions which extend from the lower terminal portion to both sides in the circumferential direction inside the cover portion and connected to the upper terminal portion from both sides in the circumferential direction.
