Abstract

A mobile terminal includes: a case unit including a plurality of case parts; a waterproof member that waterproofs the plurality of case parts; an inner space formed by the plurality of case parts and the waterproof member; a sound output unit in the inner space; an electronic component in the inner space; at least one processor controlling the sound output unit; a resonance space in the inner space that resonates sound from the sound output unit; and a sound hole at one side of the case unit that outputs a first sound. A sound pressure level of a second sound output by vibration of the case unit due to the first sound is higher than that of the first sound in a low-frequency range, and when the case unit is on a mounting surface, a third sound is generated by the mounting surface due to vibration of the second sound.

Dependent claims

A mobile terminal comprising:

a case unit comprising a plurality of case parts defining an outer appearance;
a display unit mounted on a front surface of the case unit;
a waterproof member configured to waterproof a gap between the plurality of case parts;
an inner space formed by coupling of the plurality of case parts with the waterproof member;
a sound output unit mounted in the inner space;
an electronic component mounted in the inner space;
at least one processor configured to control the sound output unit;
a resonance space being remaining space in which the electronic component is mounted in the inner space and configured to resonate sound that is output from the sound output unit;
and
a sound hole provided at one side of the case unit and configured to output a first sound,
wherein the case unit comprises:
a side case covering a lateral surface of the case unit;
a rear case positioned on a rear surface of the case unit and having a flat surface;
