Abstract
A vibration motor is used for a terminal device. The terminal device is provided with a middle frame having a first avoiding hole. The vibration motor includes a housing. The housing is provided with an accommodating space inside. The housing includes a first wall plate. The first wall plate is provided with a first protruding portion that protrudes outwards. The first protruding portion is hollow inside so that a first accommodating compartment is formed. The first accommodating compartment communicates with the accommodating space. When the vibration motor is mounted on the middle frame, an outer surface of the first wall plate faces the middle frame and the first protruding portion is accommodated in the first avoiding hole.
