Abstract: An earphone includes a first earphone body, a connecting arm, and a second earphone body, where the connecting arm is connected to the first earphone body and the second earphone body. A center of an outer surface of the first earphone body, a center of an outer surface of the second earphone body, and a center of an outer surface of the connecting arm are connected to each other to form a symmetry plane. First and second vent holes in the earphone are symmetrical with respect to the symmetry plane. A main antenna unit and a parasitic antenna unit in the earphone is symmetrical with respect to the symmetry plane.

Abstract: Embodiments of this application provide an image processing method. The method includes: A plurality of images that meet a first condition are determined, where the first condition includes that a similarity between any two images in the plurality of images is greater than or equal to a first threshold. A first image that meets a second condition is determined from the plurality of images, where the first image includes a first object, and the first object is a to-be-eliminated object in the first image. A second image is determined from the plurality of images, where the second image includes a second object, and a position of the second object in the second image corresponds to a position of the first object in the first image. The first object is covered by or replaced with the second object, to obtain a target image.
