The utility model discloses a portable type electronic device comprising a main body, a plurality of supporting racks, and a plurality of horn bodies. The main body comprises a rear cover provided with at least an accommodation groove, and inner parts of the plurality of the supporting racks are provided with accommodation spaces. Each of the plurality of supporting racks comprises a plurality of sound outlet holes, and the plurality of supporting racks are connected with the rear cover, and can be rotated with respect to the rear cover to form a folding state and an expanding state. In the folding state, the plurality of the supporting racks are accommodated in the at least one accommodation groove, and the plurality of the sound outlet holes face the direction of the outer side of the accommodation groove. In the expanding state, at least a part of the plurality of the supporting racks are extended out of the accommodation groove, therefore the main body can abut against the plane by using one side of each the plurality of the supporting racks, and then the main body can be vertically and inclinedly disposed on the plane. The plurality of horn bodies are respectively disposed in the accommodation spaces of the supporting racks, therefore the sounds can be generated by the vibration. The volumes of the accommodation spaces are larger than the volumes of the horn bodies, therefore the sound resonance can be generated in the accommodation spaces. The portable type electronic device has a better sound effect.
