A portable electronic communication device (110) includes a base (150), a cover (160), and a receiver (118). The base (150) has a front surface (150a). The cover is mounted to the base in such a way that the cover can be folded upon, unfolded from, and turned around the base. The cover has a compartment (180), a front surface (160a) and a rear surface (160b). The front surface and the rear surface of the cover have a number of first apertures (124a) and a number of second apertures (124b) respectively, and the compartment communicates with an outside of the cover through the first apertures and the second apertures. The receiver is deposited in the compartment between the first apertures and the second apertures. Sound generated by the receiver can radiate out of the cover through the second apertures or the first apertures of the cover while the cover is folded upon the base in such a way that the front surface or the rear surface of the cover rests on the front surface of the base.
