Patent ID: 7589446

Claim:
A surface mount type vibration motor mounted on a board surface of a circuit board comprising: a vibration motor body where an eccentric weight is attached to an output shaft end, a motor holder for holding a barrel of said vibration motor body, pedestals for supporting said motor holder so that an output shaft of said vibration motor body is parallel with said board surface on which said vibration motor body is mounted, and power supply terminals electrically connected by soldering to power supply lands of said circuit board for energizing a drive mechanism inside said vibration motor body, wherein said pedestals of said motor holder are spaced apart along a length of said motor body and are in contact with stationary lands of said circuit board, each of said pedestals are provided with a support plate extending in an axial direction of said output shaft, the ends of said support plates being out of contact with one another along their length and are arranged between a center of gravity of said eccentric weight and an end surface of said eccentric weight along said axial direction, and said support plates are not arranged along their length in a position where a distance between said eccentric weight and said circuit board is a minimum.
