LINEAR MOTOR

摘要

PURPOSE: A linear vibration motor is provided to improve the properties of the motor by installing a PCB to surround a part of the outer surface of a magnet for not contacting the magnet when a vibration part vibrates. CONSTITUTION: A stator part comprises magnets(111a,111b), a case(112), a bracket(113), and a plate yoke(114). The case forms internal space in order to cover the stator part. The stator part comprises a coil(121), a heavy body(122), a PCB(123), a damping member(124), and a circular yoke(126). The coil faces the magnet. The PCB is installed in order to surround at least a part of the outer periphery of the magnet. An elastic member(125) connects the stator part and to the vibration part.
