Abstract: A smart laser phone includes a main body with a mobile communication module, a band connected to the main body, an optical member, on a side surface of the main body to which the band is not connected, for projecting a laser image, a speaker on the same side surface as the optical member but separated by a set distance therefrom, a sensor unit on the surface between the optical member and the speaker, and a microphone on the outer side of the optical member. When the smart laser phone is worn on the wrist, the microphone and the optical member, the sensor unit and the speaker are sequentially equipped on the side surface of the smart laser phone main body oriented toward the palm, and thus, as the phone is used with an enlarged image, using the phone is convenient, and communication can be carried out with clear sound.
