An exemplary portable electronic device includes a front cover having a display panel mounted thereon, a rear cover connected to the front cover, and two speakers received between the front cover and the rear cover. The rear cover defines two recesses in two side portions thereof. Each side portion of the rear cover defines sound emission holes communicating with the recess. Each speaker is located adjacent to and faces corresponding sound emission holes. Sound produced by each speaker transmits through the corresponding sound emission holes along a vertical direction perpendicular to the display panel, and spreads to the outside environment through an adjacent recess.
