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.

Abstract: A method for deformation measurement is provided. When the mobile platform moves to a first monitoring position in an area to-be-measured, a first image is obtained by photographing J1 monitoring points in a first area to-be-measured in the area to-be-measured, and a second image is obtained by J2 monitoring points in a second area to-be-measured in the area to-be-measured. When the mobile platform moves to a second monitoring position, a third image is obtained by photographing the J1 monitoring points, and a fourth image is obtained by photographing the J2 monitoring points. J1 first monitoring points are determined according to the first image and the third image, and J2 second monitoring points are determined according to the second image and the fourth image. A horizontal displacement amount and a vertical subsidence amount of each of the J1 first monitoring points and the J2 second monitoring points are obtained.
