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.
