VIBRATION MOTOR
Document Type and Number:
Japanese Patent JP2016073104
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To solve the problem that vibrations of a vibration part are blocked by deforming a spiral elastic part of a circuit board and tilting the vibration part when vertically vibrating the vibration part in a vibration motor.SOLUTION: The vibration part of the vibration motor comprises a coil part that faces a magnet part in a radial direction, and a mass part that is fixed to the coil part. The circuit board includes: a lower terminal part which protrudes from between a cover part and a base part to the radial outside of the cover part and is fixed onto a top face of a base protrusion; an upper terminal part which is fixed to a lower part of the vibration part and electrically connected to the coil part; and two legs which extend from the lower terminal part to both sides in a circumferential direction inside of the cover part and are connected from both the sides in the circumferential direction to the upper terminal part.SELECTED DRAWING: Figure 6
