Abstract
A distance sensing assembly and a mobile terminal including the same are provided. The distance sensing assembly includes: an emitter array, a receiver array and a reflective mirror. The emitter array, the receiver array, and the reflective mirror are located below a cover plate of the mobile terminal. An orthographic projection of the reflective mirror on a plane of the cover plate covers at least a portion of a gap between the cover plate and an earpiece of the mobile terminal. Infrared light emitted by the emitter array passes, after being reflected by the reflective mirror, through the gap to be emitted out. The receiver array receives returned infrared light which is reflected, after passing through the gap, by the reflective mirror.
