VIBRATION MOTOR

摘要

PURPOSE: A vibration motor is provided to widen a frequency band at which resonance occurs by generating electromagnetic force or elastic linearity. CONSTITUTION: A magnet is inserted into a hollow coil unit(130) and generates an asymmetrical magnetic field in a vibration direction. A vibration unit(200) includes the magnet. An elastic unit elastically supports the vibration unit. An elastic unit(400) elastically supports the vibration unit.
