Abstract

An electronic device is provided. The electronic device includes a housing, an infrared transmitter, a light guide member, and a decorative sheet. The infrared transmitter and the light guide member are both disposed in the housing. The housing is provided with a through hole, and at least a part of the light guide member is disposed in the through hole. The light guide member has a first end and a second end that are opposite to each other. The first end has a curved surface protruding opposite to the second end. The infrared transmitter is opposite to a light inlet surface, and the infrared transmitter emits infrared light toward the light inlet surface. The second end has a light outlet surface. At least a part of the infrared light incident in the light guide member through the light inlet surface emits on the light outlet surface.
