Abstract
In recent years, a design where a microphone is not located in a position appropriately facing the oral cavity of an operator has been widely adopted from a viewpoint of convenience of miniaturization and mounting of a mobile telephone. When telephonic communication is made with such a mobile telephone, if a voice of the other party for telephonic communication is hard to hear, the operator necessarily tightly presses his/her face against a front surface of a chassis. Thus, the sensitivity and sound collecting property of the microphone are reduced. In the present invention, when a sound hole as a voice transmission path is formed in the vicinity of a manipulation section, slits are formed in the peripheries of the manipulation section and the sound hole. Hence, even in a situation in which an operator necessarily tightly presses his/her face against a front surface of a chassis, the voice transmission path is ensured to a certain extent, and thus the sound collecting property is ensured to some degree or more.
