• a housing;
• a main board inside the housing;
• and
• a speaker module on the main board,
• wherein the speaker module comprises:
• a speaker housing comprising a first speaker housing defining at least one first surface of the speaker module and a second speaker housing defining at least one second surface of the speaker module that is opposite to the at least one first surface;
• a speaker assembly comprising a voice coil and a vibration member, the speaker assembly being accommodated in an interior of the speaker housing;
• a back volume in an interior of the speaker housing and defined by the first speaker housing and the second speaker housing;
• and
• a side surface shield member between an inner surface of the speaker assembly and the back volume, the side surface shield member comprising a ferrite-based magnetic substance, and
• wherein at least one vent hole communicating the speaker assembly and the back volume is in the side surface shield member.
