Portable electronic device
A portable electronic device having a speaker module is provided. The speaker module includes: a speaker unit; a back chamber; an acoustic region coupled between the speaker unit and the back chamber; and a porous material at least partially filling a portion of the front chamber, the back chamber, or the channel, for improving and extending bass performance and relieving a acoustic effect caused by the acoustic region coupling the speaker unit and back chamber. Moreover, the portable electronic device is advantageously able to compensate a resonance degradation caused by the porous material.
