Abstract: The present application relates to the technical field of electronic devices, and in particular, to an accessory body and an accessory. The height of the accessory body is less than the contour diameter of the projection plane, and a projection of the accessory body on a plane which is perpendicular to a height direction of the accessory body is the projection plane, and the accessory body has at least one first light-emitting element, and light of the first light-emitting element is emitted from a peripheral side of the accessory body. In this way, it can make it easy to put on the accessory body. Moreover, it can make it easy to track and position the accessory body through light of the first light-emitting element, improve the accuracy of positioning and enhance the user experience.
