Abstract: A mobile terminal is provided that does not have a separate dedicated microphone hole. The mobile terminal preferably includes an ear jack assembly and a microphone unit. The ear jack assembly includes an ear jack plug insert hole. The microphone unit is disposed in a neighborhood of the ear jack assembly. The microphone unit is realized to use a microphone hole for receiving an external note also as an ear jack plug insert hole. Since a microphone hole for a speaker phone is excluded, the microphone unit is advantageous in space utilization, and can contribute to designing an elegance appearance of the mobile terminal. In addition, since the microphone unit is manufactured integrally with the ear jack assembly, manufacturing costs reduce and working efficiency may increase.
