ABSTRACT:
The present invention relates to a mobile terminal such as a mobile telephone or the like which has a speaker built in, and realizes a sound emission structure for separately extracting the front output and back output of the speaker in a plurality of directions. The construction of this mobile terminal comprises a first sound emission part which is formed in one surface part of a case having a speaker built in, and which conducts the front output of the speaker to the outside of the case, a sound conducting hole which is formed in case internal members disposed inside the case, and which causes the back output of the speaker to pass through the interior of the case, and conducts this output to the other surface of the case, and a second sound emission part which is formed in the other surface part of the case, and which conducts the back output from the sound conducting hole to the outside of the case.
