<p>PROBLEM TO BE SOLVED: To provide a portable electronic device with a speaker module, capable of securing the quality of sound of speakers and further effectively reducing the total thickness of the portable electronic device.SOLUTION: A portable electronic device comprises: a first housing; a second housing; a circuit board; a speaker module; and an antenna module. Two speakers of the speaker module are mounded on a one side surface of the circuit board corresponding to sound emission holes, respectively, so as to be spaced from each other, and are received in two receiving recessed parts, respectively. The receiving recessed parts communicate the sound emission holes to form a front resonating chamber for the speakers. The circuit board is provided with a third through hole corresponding to the position of a second through hole. The antenna module is mounded on the other side surface of the circuit board corresponding to the speakers. A first through hole, the second through hole, the third through hole, a recessed space of the antenna module and the sound emission holes sequentially communicate with each other to form a back resonating chamber for the speakers.</p> |
