PURPOSE: A mobile terminal is provided to eliminate an extra manipulation key for a terminal body by performing volume control with the manipulation of a plug. CONSTITUTION: A circuit substrate (281) forms a space separated from a support member. The circuit substrate places an electronic element on a surface facing the support member. The circuit substrate includes an opening to expose a speaker. A rib (411) is protruding from the support member. The rib forms a closed loop surrounding the speaker. One or more parts of the rib touch the circuit substrate to block a sound spread to the separated space.
