Abstract

An object of the present invention is to provide a mobile terminal in which a sound path can be secured around speaker sound holes when the mobile terminal is placed and which can thereby provide stable sound to a user. A mobile terminal according to the present invention is a mobile terminal in which an upper housing including a display unit is connected to a lower housing ( 1 ) including an operation unit in a freely-movable fashion and a speaker sound hole ( 7 ) is formed in a surface of the lower housing ( 1 ) opposite to the operation unit (rear surface), in which the rear surface is configured so as to be inclined with respect to a placing-surface ( 6 ) when the mobile terminal is placed on the placing-surface so that a space ( 9 ) that allows speaker sound to be released is formed between the rear surface and the placing-surface, and a protrusion ( 4 ) is formed near the speaker sound hole ( 7 ). As a result, a sound path is secured around the speaker sound hole ( 7 ), and therefore stable sound can be provided to a user.

Claims (7)

1. A mobile terminal wherein a second housing comprising a display unit is connected to a first housing comprising an operation unit in a freely-movable fashion and a speaker sound hole is formed in a rear surface of the first housing opposite to the operation unit, wherein:

the rear surface is configured so as to be inclined with respect to a placing-surface when the mobile terminal is placed on the placing-surface so that a space that allows speaker sound to be released is formed between the rear surface and the placing-surface,

the speaker sound hole and a protrusion formed near the speaker sound hole are formed in a part which is inclined with respect to the placing-surface,

wherein when the second housing forms a right angle or an acute angle with the first housing, the protrusion is not in contact with the placing surface and the space is maintained by the inclined part,

wherein when a position of the second housing is changed and a center of gravity of the mobile terminal is thereby shifted toward the second housing, the protrusion comes into contact with the placing-surface and the space is thereby maintained; and

wherein the speaker sound hole comprises a plurality of speaker sound holes, and wherein the protrusion is disposed at a center of these plurality of speaker sound holes.

2. The mobile terminal according to claim 1 , wherein when a center of gravity of the mobile terminal is shifted toward the second housing as a result of a movement of the second housing, the protrusion comes into contact with the placing-surface.
