摘要:
A linear vibration motor wherein the amplitude along the direction of thickness is limited, and wherein vibration is produced with a large thrusting force while securing adequate mass in the weight. The linear vibration motor comprises: a coil that is supported over a bottom plate that faces a top face portion of a case, and that is wound along a plane that is perpendicular to the bottom plate; a magnetic pole portion that is able to produce a thrusting force in the vertical direction through an electric current that flows in the coil; a weight that vibrates integrally with the magnetic pole portion; and an elastic member that supports the weight on the top face portion of the case so as to enable vertical vibration.
