Abstract

PURPOSE: A flat-type vibration motor is provided to improve a vibration characteristic while reducing a size and a thickness and to reduce a power consumption. CONSTITUTION: Permanent magnets are inserted in a circle plate(10), which is formed using an iron plate for preventing flux leakage, so as to be opposite to each other. An eccentric plate is assembled by push fitting a bearing(14) having a shaft-fixed hole and attaching a brush(13) on an electric insulator(11). A pattern is formed on a printed circuit board(21), and a plurality of coils are disposed in the same angle on a circumference. The coils are attached at a lower case(23) where a shaft(24) is press-fitted.
