Abstract
In a portable communication apparatus of the invention, an inner wall () of an openable/closable member () faces the front face of a diaphragm of a close-talking microphone () via a sound path (), and an outer sound hole () faces the rear face of the diaphragm of the close-talking microphone () via a sound path (). An inner sound hole () is biasedly located in a position which is close to a free end of the openable/closable member (), and the outer sound hole () is biasedly located in a position which is close to the center position of opening and closing movements of the openable/closable member (), thereby obtaining a speech quality of a very high S/N ratio at a substantially same degree in both the cases where the openable/closable member () is opened, and where the member is closed.
