    摘要： A vibration motor and speaker device includes a speaker excitation magnet around a flat brushless vibration motor which acts as a speaker magnetic pole. the vibration motor has a case constituting motor housing that comprises a magnetic body on a lateral periphery, a ceiling portion made of a nonmagnetic body, and a detent torque generation part disposed on a bracket and receiving the magnetic field of a rotor magnet. The detent torque generation part is separated from the magnetic body portion of the motor housing thus reducing effects of the magnetic field of the speaker excitation magnet.
