Abstract
A flat type vibration motor with increased vibration amount comprises a vibrator (1), a hard circuit board (2), a rotor (3), a shaft (5), a lower case (9), a magnet (8), a flexible circuit board (11), a brush (10) and winding coils (a, b). The rotor (3) is formed by injection-molding the vibrator (1). The winding coils (a, b) and the hard circuit board (2) are both mounted on the vibrator (1), thus the outer edge of the vibrator (1) can be extended to the position beyond the winding coils (a, b) and the hard circuit board (2).
